Hindfoot nailing for displaced ankle fractures in the elderly: A case-control analysis

IntroductionManagement of fragility ankle fractures in the elderly poses a surgical dilemma. An alternative to open reduction and internal fixation (ORIF) with screw and plate construct in selected elderly patients who may be significantly frail and comorbid is a tibio-talo-calcaneal (TTC) or hindfoot nail. Hindfoot nailing potentially reduces the risk of wound infection and increases likelihood of earlier return to function by allowing earlier weightbearing. The aim of this study was to examine the outcomes and complications of patients who received a hindfoot nail compared to patients who underwent an ORIF.MethodsA retrospective review identified patients who underwent hindfoot nailing from Jan 2010 to Dec 2021. Patients aged >65-years who underwent ORIF in the same time period were concurrently identified. The patients in the ORIF group were matched with patients in the hindfoot nail group by age, gender, comorbidity according to their Charlson Comorbidity Index (CCI) and their pre-injury function by Karnofsky Performance Scale (KPS). Clinical Frailty Scale (CFS) was also collected as part of patient demographics. Outcomes examined include mortality, length of stay, operation time, return to previous mobility, wound complications, metalware failure and infections.ResultsTwenty-six patients were identified in the hindfoot nail group and matched to 26 patients who underwent ORIF. Mean age was 84 and 83 years in the nail and ORIF group respectively. Overall, there were 12 and 11 complications from the hindfoot nail and ORIF group respectively with seven and two requiring return to theatre in the nail group and ORIF group (P = 0.07). The hindfoot nail group waited an average of 22 days after the operation for weightbearing compared to 59 days in the ORIF group (P < 0.001). There were no significant differences in length of stay (P = 0.58) and operation time (P = 0.19).ConclusionHindfoot nailing was associated with an increased risk of complications and higher risk of return to the operating theatre. Despite the potential attraction of earlier weightbearing, surgeons and patients need to be aware of these potential pitfalls.     

Distal locking in short hip nails: Cause or prevention of peri-implant fractures?

ObjectivesThe most common cause of femoral fractures after osteosynthesis of trochanteric fractures with short nails is weakening of the femoral cortex via distal locking and stress concentrations at the tip of the nail. The aim of the study was to verify whether the incidence of peri-implant fractures is dependent upon the distal locking technique.MethodsWe prospectively analysed a group of 849 pertrochanteric fractures (AO/ASIF 31-A1 + 2) managed with short nails from 2009 to 2013. Unlocked nailing was performed in 70.1% and distal dynamic locking was performed in 29.9%. The mean age was 82.0 years. Peri-implant fractures were divided into 3 groups according to the height of the fracture in relation to the tip of the nail.ResultsIn total 17 fractures (2.0%) were detected. One peri-implant fracture occurred after locked nailing, whereas 16 cases occurred after unlocked nailing (p = 0.037). Patients without distal locking had an 85.7% greater risk of peri-implant fracture. Fractures of the proximal femur (Type I) occurred significantly earlier than fractures at the tip of the nail (Type II) (p = 0.028).ConclusionUnlocked nails do not guarantee sufficient stability. Distal locking serves to prevent postoperative femoral fractures. We recommend the routine use of distal locking when utilizing short nails.     

High incidence of osteochondral lesions after open reduction and internal fixation of displaced ankle fractures: Medium-term follow-up of 100 cases

BackgroundThe incidence of osteochondral lesions (OCLs) in association with displaced ankle fractures has only been examined in two previous studies. In both studies magnetic resonance imaging (MRI) was performed prior to open reduction and internal fixation (ORIF). Because MRI may overdiagnose or overestimate the extent of OCLs in an acute trauma setting the aim of this study was to determine the incidence of OCLs after ORIF of displaced ankle fractures using MRI at medium-term follow-up, and to analyse if the severity of fracture or the clinical outcome correlates with the incidence of OCLs.Patients and methodsFollowing institutional review board approval a total of 100 patients (mean age, 41.3 years; range, 17.9–64.3 years) with a displaced ankle fracture who had undergone ORIF according to the AO principles were included in this study. The American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot score was used to quantify the clinical outcome and MR images were evaluated for OCLs of the talus and distal tibia after a mean of 34.5 months (range, 17.5–54.1 months).ResultsOCLs were found in 40.4% of the patients. Logistic regression revealed a significant correlation between the severity of fracture and the incidence of OCLs. Patients with a trimalleolar fracture (p = 0.04) or an ankle fracture dislocation (p = 0.003) had a significantly higher risk for developing an OCL compared to those with a type B fracture. Logistic regression also demonstrated a significant correlation between the clinical outcome (AOFAS score) and the incidence of OCLs (p = 0.01). The risk for developing an OCL increases up to 5.6% when the AOFAS score decreases by one point.ConclusionOCLs were frequently found in association with acute ankle fractures at medium-term follow-up, and the severity of fracture was associated with an increased number of OCLs. Considering the disadvantages of MRI including the high cost and limited availability, the results of this study may help to explain why anatomic surgical realignment of displaced ankle fractures may still be associated with poor clinical outcomes.     

Effectiveness of arthroscopically assisted surgery for ankle fractures: A meta-analysis

IntroductionThis meta-analysis was performed to determine whether the arthroscopically assisted open reduction and internal fixation (ORIF) for ankle fractures is more beneficial than the conventional ORIF.MethodsArticles in electronic medial databases were searched between March 1983 and August 2016, including Pubmed and SCOPUS. We included the studies with comparative design comparing the surgical outcomes between the arthroscopically assisted ORIF for ankle fractures and the conventional ORIF. Finally, two RCTs and two retrospective comparative studies were included for analysis. Mean and standard deviation (SD) of postoperative functional scores, number of subjects, and P-values were extracted from the studies. In addition, postoperative follow-up period, fracture type, and study quality were collected.ResultsThe pooled effect size of the four studies 0.535 (95% CI, 0.247–0.823) in Hedges’s g, which favored the arthroscopically assisted ORIF over conventional ORIF. There was no evidence of publication bias in funnel plot and in Egger’s test (p = 0.534).ConclusionThe arthroscopically assisted ORIF for ankle fractures were more beneficial than the conventional ORIF in the current evidences. However, since it needs more medical cost and longer operation time, possible additional complications and cost effectiveness are to be validated in future studies.     

Impact of intermittent pneumatic foot pumps on delay to surgery following ankle fracture

BackgroundAnkle fractures requiring open reduction and internal fixation (ORIF) are common and place considerable burden on inpatient beds. ORIF cannot be performed once the associated swelling is too excessive to permit tension-free wound closure. Where ORIF cannot be performed before the onset of swelling in the first 24–48 h, patients typically require up to 7 days of inpatient bed-rest and elevation to reduce swelling to an acceptable level for ORIF.The primary aim of this study was to determine whether delay to ORIF could be reduced with the pre-operative application of an intermittent pneumatic foot pump (IPF). These devices were designed as anti-embolic adjuncts, but have also been shown to be effective in the reduction of swelling.We compared 12 patients managed with an IPF to 12 matched historical controls who were not.No previous studies have addressed this question in unselected patients requiring ankle ORIF.MethodsWe performed a retrospective, controlled, before and after study of 24 patients who underwent ankle ORIF at our orthopaedic unit. Foot pumps were applied in the Accident and Emergency Department to ankle fracture patients requiring admission, and kept in place until ORIF.Data was collected from patient case notes for all patients.Patients were matched for age, gender, American Society of Anaesthesiologists (ASA) Grade, and pre-injury mobility. The primary outcome measure was time to surgery. We also recorded total hospital stay, and calculated cost savings.ResultsPatients managed with IPFs had a statistically significant 50% reduction in time from presentation to surgery compared to those managed without (p = 0.024), and had a reduced hospital stay (p = 0.116). This resulted in a net saving of £10,480 (£953 per patient).ConclusionsWe conclude that foot pumps reduce the time to surgery and total hospital stay of patients requiring ankle ORIF, and are cost effective.     

External versus internal fixation for arthrodesis of chronic ankle joint infections — A comparative retrospective study

BackgroundArthrodesis of the ankle is a salvage procedure in case of chronic ankle joint infection. External fixation still is the gold standard.We compared the outcome of external fixator versus intramedullary nailing for arthrodesis of the infected ankle joint.MethodsAll patients with ankle joint infection who received arthrodesis with either external fixator or intramedullary nail between 08/2009 and 09/2017 were retrospectively analyzed. Endpoints were the successful control of infection, osseous fusion, and mobilization with full weightbearing.ResultsSeventy-one patients were included. Nineteen patients (27%) suffered reinfection. Patients with intramedullary nailing showed significantly fewer reinfections (p = 0.019), achieved full weightbearing significantly more often (p = 0.042) and faster and developed significantly fewer complications (p < 0.001). Forty-three patients showed bone fusion without significant differences between the groups.ConclusionsAnkle arthrodesis with intramedullary nailing appears to be a successful alternative to the established procedure of external fixation in cases of chronic ankle joint infection.     

A comparison of treatment setting for elderly patients with hip fracture,is the geriatric ward superior to conventional orthopedic hospitalization?

IntroductionHip fractures in the elderly are a major cause of morbidity and mortality. The treatment settings of these patients may change their outcomes. The aim of this study is to compare the outcomes of patients with displaced femoral neck fractures who were admitted to the orthopedic vs. geriatric wards.Patients and methodsA retrospective study was conducted on 217 consecutive older patients with 219 displaced femoral neck fractures admitted either to the orthopedic or the geriatric ward between Jan. 2013 and Jun. 2015. Information regarding demographic, medical history, surgical management, hospitalization, and one year readmissions and mortality data was retrieved from electronic charts.Results102 hemiarthroplasty patients were admitted to the orthopedic ward and 117 to the geriatric ward. Patients' characteristics, including age, living arrangements, mobility status and the Charlson Comorbidity Index were similar between groups. Patients from the orthopedic ward had shorter hospitalization time (9 ± 5.1 vs. 10.8 ± 6.7 days, p = 0.022) and presented a lower in-hospital complication rates (0.6 ± 0.96 vs. 1 ± 1.9, p = 0.022), namely fewer events of urinary retentions, urinary tract infections and pneumonias (8.8% vs. 23.9%, p = 0.004, 3.9% vs. 14.5%, p = 0.010 and 2.9% vs. 12.2%, p = 0.034, respectfully). Readmission rates were similar. Neither in hospital nor one year mortality rates differed between groups.ConclusionsOur study found that geriatric care was not superior to orthopedic directed management in the treatment of elderly patients with hip fractures in terms of in-hospital complications, and hospitalization times.     

Increased risk of adverse events in management of femur and tibial shaft fractures with plating: An analysis of NSQIP data

BackgroundThe management of femoral and tibial shaft fractures has long been among the simplest in orthopaedic trauma. Little data exist on the predictors of complications associated with these fractures. The evolving healthcare system is creating a focus on quality metrics and changing payment models. It is critical that traumatologists develop a better understanding of complication rates associated with these injuries so that they may continue to improve patient care while also reducing overall medical costs.MethodsUsing the ACS-NSQIP database, we evaluated patient demographics, comorbidities and 30-day complications of femoral and tibial fractures. A bivariate analysis was then used to compare rates of minor and major post-operative complications within 30 days. A multivariate logistic regression was performed, assessing the odds of developing a minor and/or major complication up to 30 days post-surgery.Results2891 patients were identified. For femoral fractures, intramedullary nailing (IMN) demonstrated an overall complication rate of 14.9% (n = 151) whereas open reduction and internal fixation (ORIF) with plating showed an overall complication rate of 15.6% (n = 70). Patients undergoing plating of the femur or tibia were 2 times more likely than the IMN patients to demonstrate postoperative complications.ConclusionOur study is the first to demonstrate that plating of femoral and tibial fractures doubles the odds of developing a complication. As our healthcare system shifts to bundled payment plans, it is impertinent for the orthopaedic surgeon to understand the risk factors associated with fracture treatments in order to assess the best treatment plan.     

Displaced ankle fractures in the geriatric population: Operative or non-operative treatment

In the current study we retrospectively reviewed the outcome and complications of 118 patients over 70 years of age, with displaced ankle fractures. Six patients had open ankle fractures, all treated with open reduction and internal fixation (ORIF). The complication rate of these patients was very high: two below knee amputations and one death due to sepsis. From the 112 patients with closed ankle fractures included in the study, 72 were treated with ORIF and 40 patients were admitted for manipulation under anaesthetic (MUA) and application of cast. The latter had 27.5% failure rate (patients requiring surgery at a later stage) and a 17.2% re-intervention rate (patients requiring re-manipulation to maintain fracture reduction).We report a 4.1% minor wound complication rate (delayed wound healing) and a similar rate of major wound complication (one below knee amputation and two wounds breakdown) in the group treated operatively. One patient in this group developed a non-union of the fracture, requiring arthrodesis of the ankle. Return to pre-injury mobility level was higher (72% versus 47%, p < 0.005) for the patients treated with ORIF. The results of our study indicate that open reduction and internal fixation of ankle fractures in geriatric patients is efficacious and safe in selected patients and age alone should not dictate the treatment of the ankle fractures in geriatric population.     

Traction table versus manual traction in the intramedullary nailing of unstable intertrochanteric fractures: A prospective randomized trial

IntroductionThe purpose of this prospective randomized study was to compare traction table with manual traction for the reduction and nailing of unstable intertrochanteric femur fractures.DesignProspective, randomized, two-center trial.Materials and methods72 elderly patients with AO/OTA 31A2 and 31A3 proximal femur fractures were randomized to undergo surgery with either manual traction (MT) or traction table (TT) facilitated intramedullary nailing. The demographics and fracture characteristics, duration of preparation and surgery, total anaesthesia time, fluoroscopy time, blood loss, number of assistants, early post-operative radiological evaluations and 6th month functional and radiological outcomes were evaluated. Data of 64 patients attending 6th month follow-up examination were evaluated statistically.ResultsNo significant differences were observed between groups regarding demographics and fracture characteristics. In the manual traction group, there was a significant time gain in respect of the positioning and preparation period (18.0 ± 1.6 min in MT group, 29.0 ± 2.4 min in TT group) (p < 0.05). In terms of total anaesthesia time (Preparation + surgery) approximately 6 min of difference was observed in favor of MT group (72.8 ± 14.0 min for MT and 78.6 ± 6.5 min for TT, [p < 0.05]). Median number of assistants needed was significantly lower in TT group (2 assistants [1], [2], [3]) in MT group and (1 assistant [1], [2]) in TT group [p < 0.05]). There was no significant difference between two groups regarding other surgical and outcome parameters.ConclusionsManual traction reduced the preparation time and total anaesthesia duration, despite an increase in number of surgical assistant.Level of evidenceLevel II.     

The use of interfragmentary positional screw in minimally invasive plate osteosynthesis for simple distal femur fractures in elderly patients: A retrospective,single-centre pilot study

IntroductionMinimally invasive plate osteosynthesis (MIPO) using locking plates has been used in distal femur fractures, but various problems, such as nonunion, malalignment, and implant failure, have been reported. Simple fractures sometimes have poorer outcomes than complex fractures. We studied elderly patients with simple fracture patterns who underwent open reduction followed by placement of a single positional screw to hold the reduced interfragmentary gap, and compared these cases with patients who underwent surgery using conventional MIPO techniques.Patients and methodsA retrospective analysis was conducted on 80 cases of patients with distal femur fractures and simple fracture patterns (33-A1, A2, and C1). The mean age was 74 (60–90) years, and the mean follow-up period was 14 (12–25) months. Group A included 40 patients who underwent conventional MIPO technique while Group B included 40 patients who had surgery using positional screws. Interfragmentary gaps in Group B were reduced using percutaneous reduction clamps, and cortical screws were inserted to sustain the reduction. Then, locking plates were inserted using conventional MIPO techniques.ResultsBony union was achieved in all 80 cases, mean initial callus formation was observed in 11 weeks (8–13 weeks), and radiological union was observed in 27 weeks (15–54 weeks). Time to initial callus formation was not different, but radiologic union was achieved in 30 weeks (18–54 weeks) for Group A and 25 weeks (15–41 weeks) for Group B (p = 0.006). No differences were seen in clinical function at 1 year (p = 0.580). Five cases of malalignment occurred in Group A (p = 0.021). The rate of union during the 1-year period was significantly higher in group B than in group A (p = 0.002).ConclusionsIn a distal femur fracture with a simple fracture pattern, using positional screws to sustain the reduced interfragmentary gap may achieve a more rapid union by reducing fracture gap. Though functional differences were not seen in follow-ups, patients can be expected to return to their normal lives earlier as union is achieved in a shorter time. Performing MIPO using positional screws to sustain the reduced interfragmentary gap after fracture reduction will be helpful in the treatment of simple femoral fracture.     

Internal fixation versus conservative treatment for elderly patients with a trochanteric hip fracture in conjunction with post-stroke hemiplegia

ObjectiveTo retrospectively evaluated Gamma nail internal fixation in the treatment of elderly patients with post-stroke hemiplegia experiencing trochanteric hip fracture.MethodsThe patients were obtained consecutively from January 2005 to December 2010 with inclusion criteria. The total number was 138 and allocated to two groups: treated with the Gamma nail (n = 72,group A) and continuous skin traction (n = 66,group B). Preoperative variables including patient age, gender, duration of cerebrovascular accident, duration of hypertension, ASA risk score, Harris hip score and fracture type were recorded and compared. After treatment, time of patients activity on the bed, ambulation time, Harris hip score, mortality, complications were recorded and used to compare the outcomes.Results(1) Follow-up was undertaken from 3 to 10 years, with an average of 5.8 years. (2) No statistical difference in preoperative variables was found between the 2 groups. (3) two groups had statistical significance (P = 0.000) in the time of patients activity on the bed and ambulation time and group A can activities on the bed and ambulates earlier. (4) There were significant differences between 2 groups in Harris hip score at 1 and 3 years and group A was significantly higher than group B. (5) there were statistically significant differences in mortality of 3 years, 5 years and 10 years and the group B was significantly higher than the group A. (6) There was a statistical significance in complications between 2 groups and group B was higher than group A. Major complications in group A were pain, lag screw cut out, implant infection and distal femoral fractures caused by fall after the surgery.ConclusionOn elderly patients with trochanteric hip fracture on the hemiplegic lower side, Gamma nail internal fixation treatment can achieve better effect, patients can be early activity, fewer complications, and less mortality.     

Is device-assisted reduction prior to semi-extended intramedullary nailing of distal tibial fractures necessary?

IntroductionTraditional methods of nailing distal tibial fractures have an unacceptable risk of mal-alignment due to difficulty in obtaining and maintaining reduction intra-operatively. Methods to obtain and maintain reduction when nailing these fractures, and therefore reducing the risk of Mal-alignment include modified external fixators, distractors and commercial reduction tools. Semi-extended intramedullary nailing of distal tibial fractures via a supra-patellar approach is now being used more commonly. The aim of this study was to assess whether a commercial reduction device (Staffordshire Orthopaedic Reduction Machine − STORM, Intelligent Orthopaedics, Stafffordshire, UK) is necessary to reduce the risk of mal-alignment in patients undergoing semi-extended nailing for distal tibial fractures.MethodologyA case-control study was conducted in 20 patients who had STORM-assisted reduction of distal tibial fractures prior to intramedullary nailing and 20 controls without STORM. The control group was matched for age, sex, fracture type (AO/OTA), ASA and gender. All patients had an intramedullary nail (IMN) using the semi-extended system. Primary outcome measures were coronal and sagittal mal-alignment. Secondary outcome measure was unplanned return to theatre for complications and problems with fracture healing.ResultsThere was no difference in post-operative mal-alignment in both groups. There was no significant difference in time to union in both groups Both groups had equal number of patients requiring unplanned return to theatre. The STORM group was associated with a significantly increased operative time [p = 0.007, 130.3 min (SD 49.4) STORM vs 95.6 mins (SD 22.9) Control].ConclusionIntraoperative use of STORM significantly increases operative time with no difference in outcome. The superior orthogonal views and manual control obtained during semi-extended nailing via a supra-patellar approach obviate the need for additional methods: of intraoperative reduction for this fracture group.     

Computer-assisted navigation for intramedullary nail fixation of intertrochanteric femur fractures: A randomized,controlled trial

IntroductionLag screw cutout is one of the most commonly reported complications following intramedullary nail fixation of intertrochanteric femur fractures. However, its occurrence can be minimized by a well-positioned implant, with a short Tip-to-Apex Distance (TAD). Computer-assisted navigation systems provide surgeons with the ability to track screw placement in real-time. This could allow for improved lag screw placement and potentially reduce radiation exposure to the patient and surgeon.MethodsBetween Oct 2014 and Jan 2016, patients with intertrochanteric femur fractures being treated with intramedullary nail fixation by one of three fellowship-trained orthopaedic traumatologists were enrolled. Inclusion criteria were low-energy mechanism of injury and fracture class 31-A1/A2. Open fractures and patients with multiple injuries to the lower extremity were excluded. Patients were randomly assigned to computer-assisted navigation or a conventional fluoroscopic technique for lag screw placement. The primary outcomes were TAD, measured by postoperative anteroposterior and lateral x-rays by an independent reviewer, and radiation exposure measured in seconds of fluoroscopy time. Surgical time was also recorded.Results50 patients were randomized, 26 to the computer-assisted navigation group and 24 to the control group. The mean manually-measured TAD in the computer-assisted navigation group was 14.1 mm ± 3.2 and in the control group was 14.9 mm ± 3.0 (p = 0.394). There was no difference between groups in total radiation time (navigation: 58.8 s ± 23.6, control: 56.5 s ± 28.5, p = 0.337) or radiation time during lag screw placement (navigation: 19.4 s ± 8.8, control: 18.8 s ± 8.0, p = 0.522). The surgical time was significantly longer in the computer-assisted navigation group with a mean surgical time of 45.8 min ± 9.8 compared to 38.4 min ± 9.3 in the control group (p = 0.009).ConclusionsComputer-assisted navigation consistently produced excellent TADs, however it was not significantly better than conventional methods when done by fellowship-trained orthopaedic traumatologists. Surgeons with a lower volume trauma practice could potentially benefit from computer-assisted navigation to obtain better TAD.     

Surgical complications following ESIN for clavicular mid-shaft fractures do not limit functional or patient-perceived outcome

Elastic intramedullary nailing (ESIN) has been proposed as an alternative minimal-invasive method for the operative management of mid-shaft fractures of the clavicle. However, a relevant complication rate has been reported in previous cohorts.The present retrospective single-centre study aimed to analyse the complications following ESIN in adult patients with clavicular mid-shaft fractures (Allman type I) and their impact on functional and patient-perceived outcome measures. Results were compared to a control group receiving locking plate osteosynthesis.The clinical course and outcome of operatively managed patients with clavicular mid-shaft fractures were retrospectively analysed. Patients were assigned to group A (ESIN) and group B (plate fixation). Radiological, functional (Constant Murley Shoulder Outcome Score (CS), the Disabilities of the Arm, Shoulder and Hand (DASH) Score, the Oxford Shoulder Score (OSS)), and patient perceived aesthetic and clinical outcome were measured.A total of 47 (33 male, 14 female) operatively managed patients with a mean age of 26.7 ± 14.9 years and a follow up time of 38.1 ± 19.4 months were analysed. 36 patients were treated by ESIN (Group A), whereas 11 patients received open reduction and internal plate fixation (Group B). Patients were operatively treated with a mean delay of 7.4 ± 9.3 days (group A: 6.6 ± 8.7 days, group B: 10.2 ± 11.1 days, p = 0.326) between trauma and the surgical index procedure. There were no significant differences in the functional (CS: p = 0.338, DASH: p = 0.247, OSS: p = 0.434) and patient-perceived (p = 0.346) outcome measures between both groups. Surgical complications were noted in 14 patients (group A: 12, group B: 2) and non-union in 4 patients (group A: 3, group B: 1). There was no correlation between the recorded complications as assessed by the Clavien and Dindo classification and the functional as well as the patient-perceived outcome measures.Despite a relevant incidence rate of surgical complications, ESIN provides good to excellent functional and patient-perceived results in the treatment of clavicular mid-shaft fractures.     

Prognostic risk factors for complications associated with tibiotalocalcaneal arthrodesis with a nail

BackgroundTibiotalocalcaneal (TTC) arthrodesis with a nail can be an effective salvage procedure for several foot and ankle pathologies, but has a relatively high complication rate. The purpose of this study is to investigate risk factors associated with complications after TTC arthrodesis with a nail.MethodsClinical and radiographic outcomes for 82 patients from 2012 to 2016 who underwent TTC arthrodesis with a nail were retrospectivelyevaluated to determine if patient or surgeon specific variables offered prognostic value in predicting negative outcomes.ResultsDiabetes, diabetic neuropathy, high (>2) American Society of Anesthesiologists (ASA) classification, and Charcot neuroarthropathy all were predictive of developing a nonunion in either the subtalar ortibiotalar joints (p < 0.05). Diabetic neuropathy was predictive ofreoperation, and along with HbA1C >7.5 was also predictive of hardwarefailure. The odds ratio (OR) for diabetic neuropathy was 2.99 (p < 0.05)for nonunion in the tibiotalar or subtalar joints, 3.46 (p < 0.05) for reoperation,and 4.11 (p < 0.05) for hardware failure. High ASAclassification had an odds ratio of 3.93 (p < 0.05) for nonunion in the tibiotalar or subtalar joints as well. Diabetes had an odds ratio of 2.57 (p < 0.05) for nonunion.ConclusionsPatients with diabetic neuropathy, Charcot neuroarthropathy, elevated HbA1C, and ASA classification >2 demonstrated a higher complication rate in patients undergoing TTC arthrodesis with a nail.     

The outcomes of pediatric femoral shaft fractures treated surgically by different types of orthopedists

BackgroundThe objective of this study was to compare the outcomes of pediatric femoral shaft fractures treated with titanium elastic nail (TEN) by pediatric orthopedists and non-pediatric orthopedists.MethodsFrom May 2006 to June 2014, 88 children with femoral shaft fractures were randomized to operative stabilization either by pediatric orthopedists (Group A, 44 cases) or by non-pediatric orthopedists (Group B, 44 cases). Demographic data and clinical characteristics (age, sex, weight, fracture side and type, cause of injury, associated injuries and interval from injury to surgery) were comparable between the two groups before surgery. Peri-operative data, clinical and functional outcomes between the two groups were recorded.ResultsThe mean follow-up period was 20.9 ± 4.5 months for Group A and 20.0 ± 3.6 months for Group B (P = 0.356). There was no significant difference in the time to union, length of hospitalization, full weight-bearing time and TEN scores between the two groups (P = 0.785, P = 0.835, P = 0.803, P = 0.940, respectively). However, the mean operating time and radiation time was longer in Group B than in Group A (P = 0.001 and P = 0.047, respectively). Also, there was a trend for patients of Group B to have a higher rate of open reduction (P = 0.047). When comparing the total complications, no significant difference existed between the groups (P = 0.978).ConclusionsThis study indicated that both pediatric and non-pediatric orthopedists provided satisfactory clinical and functional results in treating these common injuries.     

Outcome evaluation of minimally invasive surgery versus extensile lateral approach in management of displaced intra-articular calcaneal fractures: A randomised control trial

BackgroundMinimally invasive surgery has a significant and evolving role in the treatment of DIACFs, but there is limited literature on this topic.ObjectivesTo compare the clinico-radiological outcomes of DIACFs fixed with MIS technique with ORIF.MethodsThis randomised control trial (RCT) included 21 closed Sanders type 2 and 3 DIACFs which were selected from 70 who presented. Extensile lateral approach was used in the ORIF group; while MIS techniques included either percutaneous reduction or small incisions with indirect fragment manipulation.Main Outcome MeasurementAOFAS hindfoot score, pre-operative and postoperative radiology.ResultsThere were 9 fractures in the Extensile group and 12 in the MIS group, with both groups having comparable demography, fracture classification, surgery delay & initial radiology. Bohler′s angle improved after surgery by an average of 18.44 with ORIF and 14.67 with MIS (p = 0.28). Mean AOFAS in the MIS group was 82.58 (66.67% good and 33.33% fair) and was 89.56 (44.44% excellent, 55.56% good, 0 fair/poor) with ORIF (p = 0.034). Two patients who underwent ORIF had a major complication (one deep infection and Sural nerve injury each) while none in the MIS group.ConclusionsMIS methods minimized soft tissue complications and achieved comparable radiological reductions but clinical outcomes were poorer, with percutaneous methods having the worst outcomes.     

Proximal femoral nail antirotation versus hemiarthroplasty in the treatment of senile intertrochanteric fractures: Case report

BackgroundPrimary hemiarthroplasty was recommended by some surgeons as the preferred choice in treating unstable senile intertrochanteric fractures with osteoporosis. However, many studies reported that proximal femoral nail antirotation (PFNA) currently was as an optimal implant for the treatment of different type of intertrochanteric fractures. Which method is better for treating senile intertrochanteric fractures remains controversial due to the insufficient clinical evidences.MethodsWe reviewed all consecutive senile intertrochanteric fractures treated with PFNA or cemented hemiarthroplasty at our institution between July 2010 and March 2015. The primary outcome measures were postoperative complications, reoperation rate and hip function. The secondary outcome measures were intraoperative blood loss, transfusion rate, surgical time, postoperative hemoglobin, hospital stay and 1- year mortality.ResultsSeventy-one patients in PFNA group and 52 patients in hemiarthroplasty group were included for analysis. There were no significant differences between the two groups regarding to the orthopaedic complications, reoperation rate, surgical time and Harris Hip Score at 1 year follow-up. Significant differences were found between PFNA and hemiarthroplasty group in comparison of intraoperative blood loss (P < 0.001), transfusion rate, medical complications (P = 0.037) and hospital stay (P = 0.001). Patients treated with hemiarthroplasty had a trend of higher postoperative 1- year mortality compared to those underwent PFNA but this was statistically not significant (P = 0.134).ConclusionsThese findings indicate that PFNA has obvious advantages over hemiarthroplasty in the treatment of senile intertrochanteric fractures. Hemiarthroplasty in treating these fractures is associated with greater surgical trauma and higher incidence of postoperative medical complications.     

Intra-operative fluoroscopy time and radiation dose during suprapatellar tibial nailing versus infrapatellar tibial nailing

BackgroundFractures of the tibial shaft are routinely managed with intramedullary nailing. An increasingly accepted technique is the suprapatellar extended leg method. The aim of this study was to investigate whether the suprapatellar tibial nailing technique offers shorter intraoperative fluoroscopy times and lower radiation doses when compared to the traditional infrapatellar technique.Study design and methodsData from 200 consecutive intramedullary tibial nailing operations in our level 1 Major Trauma Centre were retrospectively collected from a prospective database (January 2014–December 2017). Only acute diaphyseal nailing procedures were included. The operations were performed by seven senior trauma consultants experienced in both suprapatellar and infrapatellar tibial nailing. The operations were divided into two groups: infrapatellar and suprapatellar. Intraoperative radiation time and dose data were collected.ResultsA total of 90 cases were included and analysed. The majority of the patients were male (82%). 37 operations were infrapatellar and 53 were suprapatellar. Independent samples t-test revealed lower radiation time and dose for the suprapatellar group. The infrapatellar group had a mean radiation time of 129.7 ± 56.6 s versus 94.4 ± 47.9 s for the suprapatellar group. The infrapatellar group had a mean radiation dose (Dose Area Product) 53.6 ± 34.2 cGY cm² versus 38.2 ± 26.7 cGY cm² for the suprapatellar group. The difference in mean radiation time and mean radiation dose were both significant (p = 0.002 and p = 0.02 respectively).ConclusionsSuprapatellar tibial nailing is an increasingly accepted technique in the management of tibial fractures. It is shown here that amongst surgeons experienced in both suprapatellar and infrapatellar nailing techniques, the suprapatellar approach trends towards lower use of intra-operative fluoroscopy as measured by time and dose and thus potentially lower radiation exposure to the operating surgeon, assistants and patient.
