Objective
To analyse whether early post-operative full weight bearing following syndesmotic ankle fixation affected radiographic outcomes suggestive of diastasis.Design
Retrospective comparative cohort study over a two year period.Setting
Level 1 trauma centrePatients/Participants
152 consecutive patients sustaining an unstable ankle fracture requiring syndesmotic stabilisation were included. Exclusions were 49 patients who had trimalleolar fixation without syndesmosis screws, one patient who had concomitant ankle and talar fracture. Five patients were lost to follow up and eleven patients were followed up in other centres. A total of 86 patients were analysedIntervention
Protected or full weight bearing.Main Outcome Measurement
The primary outcome measure was early diastasis. The secondary outcomes were late diastasis, wound complications and re-operation. Analysis of variance was used for the predictor variable of weight bearing status. We assumed a priori that p values of less than 0.05 were significant.Results
Median age was 36 (IQR 30), with 54 males and 32 females. Median follow up was 12 weeks (IQR 6). There was no significant difference when comparing weight bearing status and change in radiographic measurements intra-operatively compared to 6 and 12 week follow up radiographs (tibiofibular clear space p?=?0.799, tibiofibular overlap p?=?0.733 and medial clear space p?=?0.261).Conclusion
After surgical stabilization of an unstable syndesmotic injury, full weight bearing did not lead to syndesmotic diastasis in the early post-operative period. Full weight bearing is recommended following ankle fixation which includes syndesmotic fixation. 相似文献2.
Background
The main purpose of this study is to introduce our surgical technique and report surgical outcomes for percutaneous cable fixation in the treatment of subtrochanteric femoral fractures.Methods
Between May 2013 and April 2017, 51 patients with subtrochanteric femoral fractures treated with closed intramedullary nailing and percutaneous cable fixation were enrolled in this study. Postoperative angulation, union rate, time from injury to union, and femoral shortening were also evaluated to assess radiologic outcomes. Clinical outcomes, including range of hip flexion, walking ability, and Harris hip score at the last follow-up were evaluated.Results
Average coronal and sagittal angulation after surgery were 0.9 (range 0–5) and 0.3 (range 0–5), respectively. There was no postoperative angulation of more than 5°. Average shortening of the femur at 1-year follow-up was 2.7?mm (range 0–15). Bone union was achieved in 50 patients (98.0%) and average time to union was 18.6 weeks (range 12–48). Hip flexion, walking ability and Harris hip score at the last follow up were 115.6° (90–120), 7.9 (5–9), and 88.3 (65–100), respectively.Conclusion
Percutaneous cerclage cable fixation can provide a greater likelihood of achieving anatomical reduction and increased stability of fracture, while preserving biology around the fracture site. Thus, percutaneous cerclage cable fixation can be an effective surgical technique for the treatment of complex subtrochanteric fractures. 相似文献3.

Introduction
Horse racing is a hazardous sport. We analyzed the incidence and characteristics of jockey injuries in a typical horse race.Methods
We analyzed all injuries sustained by 224 jockeys in the last 72 years.Results
It was found that in 96.1% of the races there was at least one fall and in 28.6% of the races 50% or more of the jockeys fell. In 43.4% of the falls, the jockey was taken to the emergency room. Comparing the Palio with traditional races in other countries, a higher injury incidence rate was observed for every 100 falls (109.884 vs 27–59) and a lower concussion rate/100 falls (0.97 vs 1.8-7.4).Conclusion
The Palio is one of the most threatening races that continues today. Jockeys are at greater risk for a fall than any other race in the world. 相似文献4.
Objectives
The purpose of this study is to analyze posteromedial fragment morphology using two-dimensional computed tomography fracture mapping and to compare posteromedial fragment morphology in various Schatzker type tibial plateau fractures.Materials & methods
One hundred twenty-seven consecutive AO/OTA B- and C-type tibial plateau fractures were retrospectively analyzed using 2DCT fracture mapping. The posteromedial articular fracture angle and articular surface areas of all fractures with posteromedial fragments were calculated. Based on biomechanical studies, posteromedial fragments with coronal fracture angles >68° were considered amenable for anterolateral stabilization with standardized plating. Kruskall-Wallis non-parametric test was used for statistical comparison of morphological features of posteromedial fragments between the various Schatzker types.Results
Forty-seven out of 127 tibial plateau fractures included a posteromedial fragment. The mean posteromedial articular fracture angle was 44° (range: 2°-90o, standard deviation: 23°). Forty fragments (85%) had a fracture angle of <68°, increasing the risk for insufficient stabilization with standardized anterolateral plating. The mean articular surface area was 34% of the entire tibial plateau (range: 7%–53%, SD: 12%). There were no significant differences in posteromedial fragment morphology between Schatzker type IV, V, and VI fractures.Discussion and conclusion
Posteromedial fragments commonly occur not only in Schatzker type V and VI, but also in Schatzker type IV tibial plateau fractures. Eighty-five percent of tibial plateau fractures with a posteromedial fragment may benefit from non-standard customized lateral plating, or may require an additional medial or posterior surgical approach for fracture-specific fixation to optimize screw purchase and biomechanical stability. 相似文献5.

Introduction
Young patients with femoral neck fractures are optimally treated with reduction and stable fixation, while patients over the age of sixty-five are often treated with arthroplasty. This study analyzes in-hospital outcomes associated with total hip arthroplasty, hip hemiarthroplasty and internal fixation for treatment of femoral neck fractures in patients aged 45–64.Methods
Records of patients between the ages of 45–64, from 2002 to 2014, sustaining femoral neck fractures and treated with internal fixation, hip hemiarthroplasty or total hip arthroplasty were obtained from the Nationwide Inpatient Sample (NIS). Examined variables were age, sex and Charlson Comorbidity Index (CCI). Outcome measures included hospital length of stay (LOS), complications, and inpatient hospitalization charge.Results
From 2002–2014 74,678 femoral neck fractures were available for analysis. THA use increased from 5.3% of operatively managed fractures in 2002 to 22.3% of operatively managed fractures in 2014 (p?<?0.0001). Patients undergoing THA had higher hospital cost, higher in hospital complication rates and longer length of stay than patients undergoing internal fixation (p?<?0.0001). The in-hospital mortality for patients undergoing a hip hemiarthroplasty was higher (1.2%) than either total hip arthroplasty (0.2%) or internal fixation (0.5%) (P?=?0.007).Conclusion
This study demonstrates that the use of total hip arthroplasty in treatment of femoral neck fractures in patients from the age of 45–64 increased 4.2-fold over the study period. This treatment is associated with increased hospital cost, length of stay and complications. Additionally, as age increased in our study population, there was a stepwise increase in the use of arthroplasty, and it appears that hemiarthroplasty is being used with a different patient population. 相似文献6.
Introduction
Distal femoral fractures have many of the same challenges as hip fractures, but there has been limited research into outcomes following these. The aim of this study was to assess 30 day mortality following distal femoral fractures in comparison to hip fractures presenting to a single institution Secondary outcomes included risk factors for mortality, post-operative complications and union.Methods
A retrospective case series of all distal femoral fragility fractures in patients over 65, and hip fractures over a 5?year period at a single institution.Results
88 distal femoral fractures and 2837 hip fractures fulfilled the inclusion criteria. In the distal femoral fractures there were 80 females and 8 males with a mean age of 82.4 (range 65–103). The mean age of the hip fractures was 83.7 (range 65–106) and there were 2066 females and 771 males.The overall 30 day mortality for hip fractures was 7.7% and was 9.1% for distal femoral fractures. The risk ratio was 1.1777(95% CI 0.6009–2.3080) (p?=?0.6338). There was no significant difference in 30 day mortality between the two fracture types.Of the 88 distal femoral fractures 75 (85.2%) underwent open reduction internal fixation, 5 (5.7%) intramedullary nail and 8 (9.1%) conservative treatment. 11.4% suffered a medical complication. 9.1% patients required at least 1 further surgical procedure. The union rate was 94.3%. The 1?year mortality was 34.1%.Conclusions
There is no significant difference in 30 day mortality between distal femoral and hip fractures. Distal femoral fractures occur in a complex group of patients that is similar to hip fractures. They have high mortality and complication rates. 相似文献7.

Background
Our aim was to determine whether plasma levels of Tissue Factor (TF), Vascular Cell Adhesion Molecule 1 (VCAM-1), Interleukin 6 (IL-6) or D-dimer after foot and ankle injury could predict which patients would develop deep vein thrombosis (DVT).Methods
Patients aged 18–60 years with acute foot and ankle injury had venous blood sample to measure TF, VCAM-1, IL-6 and D-dimer within 3 days of injury. Patients had bilateral lower limb venous ultrasound to assess for DVT on discharge from clinic.Results
21 of 77 patients were found to have DVT (27%). There was no statistically significant association between levels of TF, VCAM-1, IL-6 or D-dimer and subsequent development of DVT.Conclusion
Tissue Factor (TF), Vascular Cell Adhesion Molecule-1 (VCAM-1), Interleukin-6 (IL-6) and D-dimer levels were not associated with development deep vein thrombosis in patients with acute foot and ankle injury. 相似文献8.

Background
The aim of this study was to investigate the postoperative outcomes of cementless Total hip arthroplasty (THA) following failed internal fixation for femoral neck and intertrochanteric fractures.Method
Ninety-six cementless THAs for failed internal fixation after femoral neck fracture (59, group I) and intertrochanteric fracture (37, group II) with a minimum follow-up of 3 years were analyzed. Clinical and radiologic evaluations were performed on all patients.Results
The intraoperative blood loss and operating time were significantly increased in group II (p?=?0.001, p?=?0.001, respectively). Harris hip score at last follow-up was significantly improved in group I (p?=?0.007) but, there were no differences in hospital stay, Koval score at last follow-up, and perioperative complications between both groups. Long femoral stems for diaphyseal fitting were frequently used in group II (32/37, 86%) (p?=?0.001). Radiographically, none of the acetabular cups showed evidence of migration, loosening. All cases showed stable fixation of the femoral stem at last follow-up.Conclusions
Outcomes of cementless THA following failed internal fixation for femoral neck and intertrochanteric fractures were satisfactory; increased intraoperative blood loss, operating time, and requirement of long femoral stem should be considered in the latter type of fracture. 相似文献9.

Background
It is common practice when placing cannulated screws within the femoral head when treating femoral neck fractures to avoid the thread-forms from crossing the fracture line. Despite the widespread use of cannulated screws in internal fixation of femoral neck fractures, there is no study to our knowledge that describes the ideal length of thread-forms.Purpose
The purpose of this study is to determine the thread length that will maximize purchase within the femoral head while minimizing risk of crossing the fracture line. Additional analysis was conducted to identify factors associated with the maximal possible length of treads in minimally and non-displaced femoral neck fractures.Methods
We performed a retrospective study of all patients treated for a minimally or non-displaced femoral neck fracture from April 1, 2004 through December 31, 2017. Only patients who had received a pre-operative CT or MRI scan were included. Fixation was then templated using radiographs and the distance from the subchondral bone to the fracture line was then measured.Results
The study included 127 patients. The average estimated length of lag screw threads was 33.2?±?6.67?mm, with lower quartile of 29.1?mm and higher quartile of 37.2?mm. The median was 32.0?mm and most frequently encountered estimate was 29?mm. Estimated lag screw size did not differ significantly based on age or BMI, but both height (p?<?0.001) and race (0.04) were positively correlated with estimated lag screw size and males had longer measurements compared to females, 37.2?±?7.0?mm vs 31.4?±?5.7?mm (p?<?0.001), respectively.Conclusion
In conclusion, we propose an additional lag screw thread form with length 26.0?mm to capture 90% of femoral neck fractures. 相似文献10.

Introduction
Compression fractures of the cuboid bone in children and adolescents are rare. Fracture morphology, associated lesions, treatment options and long-term outcomes of this very rare injury are published in a few case reports. This study with review of the literature aims to support the understanding of fracture pattern and optimize pathways of decision making.Material and Methods
A retrospective two-center study was performed in a patient cohort treated between 2001 and 2016. All patients aged less than 18 years who sustained a cuboid fracture were included. Age, gender, mechanism of injury, fracture morphology, amount of displacement, associated injuries, and therapy were analyzed. In the follow-up (FU), the AOFAS Midfoot Scale was investigated.Results
Fractures of the cuboid bone were diagnosed in 7 boys and 9 girls. The mean age of the patients was 10 years (range: 2.2–16.1 years). According to the classification of Fenton we detected 11 (69%) type 2, 2 (12%) type 3 and 3 (19%) type 5b fractures. Other fracture types according to Fenton were not observed. All children under 10 years sustained a type 2 fracture. Open reduction and internal fixation was performed in 5 (31%) patients. Bone grafting was not necessary. FU was performed in 14/16 patients on average after 9 years (mean; range: 1.4–16.2 years). The mean AOFAS Midfoot Scale at FU for extra-articular type 2 fractures was 100 points, whereas in intra-articular fractures (Type 3) and fractures associated with mid-tarsal disruption (type 5b) worse results were found (95 and 66 points, accordingly).Conclusion
This rare injury shows inhomogenous morphologies and offers different treatment approaches. Extra-articular Fenton type 2 lesions are the most common type of cuboid fracture in children (69%). A potential loss of length of the lateral column must be considered. In contrast to adults, type 1, 4, and 5a fractures were not found in our cohort of children and adolescents. Lower scores of the AOFAS Midfoot Scale were found with either intra-articular involvement or associated midfoot lesions. 相似文献12.

Introduction
Tibial pilon fractures are often treated with initial external fixation followed by delayed definitive fixation. It has been postulated that the external fixator pin site may correlate with infection risk. The purpose of this study was to determine whether external fixator pin-site distance from definitive implants impacts the risk of deep infection in pilon fractures.Materials and methods
A retrospective cohort study was completed at a single level 1 trauma center. All patients ages 15–65 who underwent open reduction and internal fixation (ORIF) of a distal tibial fracture (AO/OTA Classification 43) from 2007 to 2013 were included. The final study population was 133 patients. The impact of external fixation pin location (relative to the definitive implant location) on postoperative infection was measured.Results
As a continuous variable, the distance between the closest pin site and plate was 62.1 ± 44.1?mm in the infected cohort and 62.2 ± 49.7?mm in the non-infected cohort (p?=?0.991). Further analysis was performed by grouping the distances into less than 0?mm (i.e. overlapping), >0.0 – 25.0?mm, >25.0 – 50.0?mm, >50.0 – 75.0?mm, >75.0 – 100.0?mm, and >100.0?mm of separation. No significant differences were noted with regards to the risk for infection.Conclusions
Staged care has been shown to be an effective treatment strategy for AO/OTA type 43 fractures. There are many variables to consider when placing an external fixator construct. In this cohort, pin site distance from definitive implant location was not associated with an increase in deep infections.Level of evidence

Background
Intramedullary nailing is considered a “gold standard” for treatment of tibial shaft fractures. However, some types of fractures are typically considered as “difficult for nailing”. This group includes the periarticular fractures, fractures of both bones at the same level, comminuted and segmental fractures of the tibia. Fixator-assisted nailing (FAN) is an effective method treatment of these types of fractures. The main requirements for the ideal reduction device are an ease of its installation and an ability of multiplanar fracture reduction. Fixator-assisted nailing (FAN) with the use of two perpendicular to each other monolateral tubular frames perfectly meets these requirements. In this study we present this new surgical technique and the analysis of first 30 cases.Methods
A prospective analysis was conducted for 30 patients with “difficult for nailing” tibial fractures treated with fixator-assisted nailing in our institution between September 1st, 2017, and March 1st, 2018. The duration of surgery and its different stages, the time of fluoroscopy, difficulties encountered during surgery, were analyzed. Clinical and radiological methods were used to evaluated reduction quality.Results
In all 30 cases the acceptable reduction was achieved. The mean duration of the surgical procedure was 73.7?±?3?min. The mean duration of fluoroscopy 85.9?±?4.8?s. In 7 cases we faced with technical difficulties, which were successfully addressed.Conclusion
The described technique of FAN is an effective method for the treatment of “difficult for nailing” tibial fractures. Future multi-centered studies with a larger number of patients are needed to validate our results. 相似文献14.
Background and purpose
The treatment of paediatric distal radius diaphyseal metaphyseal junction (DRDMJ) fractures is a challenge. The purpose of this study was to introduce a new operative approach at the proximal “safe zone” of the posterior interosseous nerve (PIN) to treat paediatric DRDMJ fractures and analyse the safety and efficacy of antegrade elastic stable intramedullary nail (ESIN) fixation.Methods
Thirty paediatric patients with unstable and displaced DRDMJ fractures were treated by antegrade ESIN fixation from November 2015 to September 2017. We created the entrance site at the posterolateral side of the proximal radius and 2?4?cm distal to the articular surface of the radius, using the ESIN to immobilise the fractures. In the study, we reviewed patient demographics, complications, time until removal, and intraoperative time for hardware removal.Results
Complete fracture healing was achieved between 6 and 12 weeks after surgery. Except for 3 patients presenting with irritation of the skin, we did not observe any complications. Radiologically, no secondary displacement, nail migration, loss of fixation, consolidation delay, non-union, or refracture was noted.Conclusions
The antegrade ESIN fixation is a minimally invasive, easy-to-learn, alternative operative method to treat paediatric DRDMJ fractures.Level of evidence

Background
The primary aim of this study was to present the incidence of clinically significant end stage osteoarthritis (cOA) after syndesmotic fixation of ankle fractures. The secondary aim was to and identify independent predictors of cOA.Methods
A retrospective review of consecutive patients presenting to a single University affiliated institution between March 2008 and May 2010 was undertaken. Inclusion criteria were ankle fractures with syndesmotic stabilisation. Patients were excluded if pre or postoperative radiographs were missing or were lost to follow up. Data were gathered regarding demographics, fracture pattern, fixation methods, reduction parameters, screw removal, revision surgery, complications and cOA up to seven years post injury.Results
Data were available for 120 patients (86%). In total, 13 patients (11%) developed cOA. Univariate analysis showed that increasing age, open fracture, malreduction of the syndesmosis, removal of symptomatic screws, revision surgery and complications were predictors of developing cOA. Cox regression analysis revealed increasing age (hazard ratio (HR) 1.09, p = 0.006), and malreduction (HR 45.5, p = 0.001) were independent predictors of developing cOA.Conclusions
Ankle fractures with syndesmotic stabilisation represent a severe injury with a high rate of cOA. The only modifiable risk factor for developing cOA in this large series of patients was radiological malalignment. When syndesmotic stabilisation is required, careful intraoperative assessment should be undertaken to ensure the syndesmosis is reduced. 相似文献16.

Introduction
The annual incidence of proximal femoral fractures is 100–150/100,000 and continues to increase with an aging population. Cut-out of hip screws after fracture fixation has been quoted as 8% in the literature. The tip-apex distance (TAD) is the strongest predictor for cut-out after operative fracture stabilisation.The aim of this study was to evaluate the novel ADAPT system (Adaptive Positioning Technology, Stryker, USA), a navigation device for intramedullary nailing of trochanteric fractures and its effect on optimising the TAD. This is the first clinical study to evaluate this new technology.Methods
The study group of 36 consecutive patients with a pertrochanteric fracture underwent intramedullary nailing for fracture fixation using ADAPT technology, while the matched control group underwent conventional Gamma-3-nailing. Matching criteria included fracture classification, gender and age. We measured the operative time and the postoperative TAD in anteroposterior (AP) and lateral radiographs of the 72 patients.Results
The mean TAD using ADAPT was 16.9?mm (range 8.4–33.7?mm) compared with 24.9?mm (range 14.6–40.2?mm) in the reference group treated without ADAPT. Using the ADAPT system significantly improved (p?<?0.0005) the accuracy of lag screw placement but had no effect on operating time in fixation of femoral pertrochanteric fractures.Conclusion
Working with the novel ADAPT system for positioning the lag screw using the Gamma-3-nail led to a statistically highly significant reduction of the TAD compared to the reference group (p?<?0.001). The ADAPT system proved to be a very useful device in achieving higher surgical standards for the treatment of trochanteric fractures with intramedullary nailing. It enables higher accuracy in screw positioning and therefore better placement of the implant. 相似文献18.
Background
Differing mortality rates according to day of hospital admission is an area of debate, where a supposed increased rate of mortality with weekend admissions has been termed “the weekend effect”. We sought to identify the 30-day mortality rates in major trauma patients attending our Major Trauma Centre (MTC) and the underlying reasons for these.Methods
A retrospective review of data retrieved from the Trauma Audit and Research Network (TARN) database was undertaken for all patients attending between January 2013 and July 2015 with an Injury Severity Score of 9 or higher. 30-day mortality rates were calculated according to day of attendance.Results
1424 patients met the inclusion criteria. There was no significant difference in 30-day mortality between weekend attendances (7.8%) compared to those on a weekday (7.7%). 30-day mortality was highest in patients attending on Fridays (10.8%) and lowest in those attending on Sundays (5.5%). A significantly higher 30-day mortality rate was seen in patients attending on a Friday or Saturday (10.4%) compared to those attending Sunday to Thursday (6.6%) (RR 1.548). Patients with a head injury as their most serious injury on a Friday or Saturday were more likely to have GCS?<?9 (34.7% vs 24.4%) and more likely to die (22.7% vs 12%) than those attending Sunday to Thursday.Conclusion
There is no significant difference in 30-day mortality when directly comparing weekday to weekend attendances. There is a significantly higher mortality on Friday and Saturday compared to remainder of the week which appears to be explained by a greater severity of head trauma.Implications
This study provides no evidence of a "weekend effect" in this MTC but the increased severity of and mortality from head injury identified on Friday and Saturday is a public health concern which warrants further investigation. 相似文献19.
