Background
The aims of this study were to identify the artery feeding the fifth metatarsal and determine how bunionette osteotomy could injure this vessel.Methods
The nutrient artery entering the fifth metatarsal was investigated in 10 adult cadaveric lower limbs by barium injection and enhanced computed tomography.Results
The nutrient artery entered the medial aspect of the fifth metatarsal around the junction of the middle and proximal thirds obliquely from a distal direction (mean?angle 36°) in the coronal plane in all cases; in the axial plane, the point of entry and direction of the artery was medial-plantar (mean?angle 49°).Conclusions
This report revealed direction and location of the nutrient artery entering the fifth metatarsal. 相似文献2.
Aim
Comparison of unfixed, CRIF, and ORIF of the posterior malleolus fragment (PMF) regarding the frequency of trans-syndesmotic fixation and quality of reduction in trimalleolar (equivalent) fractures.Material and Methods
Retrospective registry study. Patients with a trimalleolar (equivalent) ankle fractures were identified within the departments’ fracture database. General demographics, treatment details, and fracture specific details (CT-scans) were assessed. Patients were grouped per the PMF treatment: not addressed, CRIF, ORIF.Results
236 patients (53.0?±?18.3 (range: 18–100) years), 58.1% female were eligible. The mean size of the PMF was 21.4?±?10.4% (range: 2.7–55.9%), 71.6% were ≤25% of the tibial plafond. PMF fixation: Untreated 48.3%, CRIF 18.6%, ORIF 33.1%. ORIF of the PMF significantly (p?<?0.001) reduced the frequency of trans-syndesmotic fixation (25%) compared to CRIF (61%) or untreated PMF (63%) with no significant influence of the PMF size (≤25%/>25%). ORIF resulted in a significantly (p?<?0.001) better quality of reduction (1.2?±?1.1?mm (range: 0–5?mm)) compared to CRIF (2.5?±?2.1?mm (range: 0–8?mm)) and untreated PMF (2.5?±?2.3?mm (range: 0–20?mm)). Neither the frequency of trans-syndesmotic fixation nor the quality of reduction differed significantly between untreated PMF and CRIF.Conclusion
All posterior malleolus fragments, independent of their size, should be treated by ORIF, as this restores syndesmotic stability significantly more often than untreated PMF or CRIF. 相似文献3.

Background
Fractures of the proximal humerus are often associated with lesions of the long head of the biceps (LHB) tendon. This often leads to prolonged shoulder pain. Hence, many surgeons decide to perform a tenodesis of the LHB tendon simultaneous to ORIF. The purpose of this study was to evaluate the postoperative outcome after interlocking plate fixation and biceps tenodesis for treating proximal humerus fractures.Methods
56 patients (38 females, 18 male) suffering from proximal humerus fractures who underwent surgery were retrospectively included. 26 of these 56 patients (19% Neer II, 38% Neer III, 43% Neer IV) were treated with simultaneous tenodesis of the LHB tendon when ORIF using interlocking plate fixation was performed. 30 patients (17% Neer II, 40% Neer III, 43% Neer IV) served as control group receiving only interlocking plate fixation. The patients were asked to complete the Munich Shoulder Questionnaire (MSQ) for evaluation of postoperative shoulder function. Results of the Disabilities of the Arm, Shoulder and Hand (DASH) Score and Shoulder Pain and Disability Index (SPADI) were calculated from the MSQ. Patients were clinically evaluated for a positive O’Brien test and Popeye sign.Results
The tenodesis group demonstrated significant superior outcome regarding the MSQ (mean 90.47 points vs. 79.41 points, p?=?0.006), DASH Score (mean 4.2 points vs. 16.81 points, p?=?0.017) and SPADI (mean 94.59 points vs. 83.56, p?=?0.045). Flexion, external rotation and the capability of throwing a soft ball were significantly improved in the tenodesis group compared to the control group. The O’Brien test as indicator for lesions of the LHB was positive in fewer patients of the tenodesis group (2/26, vs. 21/30, p?=?0.001). There was no significant difference of a positive Popeye Sign.Conclusion
Our results show evidence of an improved shoulder function when a simultaneous tenodesis of the LHB tendon is performed during treatment of proximal humerus fractures using interlocking plate fixation. 相似文献4.
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

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
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7.

Introduction
In this retrospective study we have analyzed a consecutive series of patients affected by isolated radial head Mason III fractures and treated with bone resection or prosthesis.Patients and methods
This study includes 24 patients affected by fractures mentioned above and treated between July 2009 and November 2015.15 patients (average age 48 y.o.) have been treated with prosthesis. The remaining 9 (average age 573) have been treated with a capitellectomy instead.From a clinical point of view, we have evaluated the patients according to main performance indicators such as range of motion, pain, instability and Mayo Elbow Performance Score as parameters.Results
We have found similar results in both group, with an average MEPS value of 95 in the prosthesis group and 966 in the radial head resection group.The range of motion was similar too: between 1,3° and 1203° in the first group and between 4,4° and 120° in the second one. No significant complication has detected in any patient.Discussion
According to most recent literature, it is not precisely defined how to treat isolated Mason III fractures, contrary to what is defined in more complex pattern, in which prosthesis are now evaluated as the best indication.Due to radial head limited contribution to elbow stability, in absence of other bony or ligamentous lesions both capitellectomy and prosthesis can be good treatment in this kind of fracture.Conclusion
According to our experience and to the most recent literature, we recommend prosthesis in patient younger than 50 y.o., high demanding or manual worker, while in other cases we think that radial head resection can be the treatment of choice. 相似文献8.

Objectives
Improved fixation techniques with optional use of bone cements for implant augmentation have been developed to enhance stability and reduce complication rates after osteosynthesis of femoral neck fractures. This biomechanical study aimed to evaluate the effect of cement augmentation on implant anchorage and overall performance of screw-anchor fixation systems in unstable femoral neck fractures.Methods
Ten pairs of human cadaveric femora were used to create standardized femoral neck fractures (Pauwels type 3 fractures; AO/OTA 31-B2) with comminution and were fixed by means of a rotationally stable screw-anchor (RoSA) system. The specimens were assigned pairwise to two groups and either augmented with PMMA-based cement (Group 1, augmented) or left without such augmentation (Group 2, control).Biomechanical testing, simulating physiological loading at four distinct load levels, was performed over 10.000 cycles for each level with the use of a multidimensional force-transducer system. Data was analysed by means of motion tracking.Results
Stiffness, femoral head rotation, implant migration, femoral neck shortening, and failure load did not differ significantly between the two groups (p?≥?.10). For both groups, the main failure type was dislocation in the frontal plane with consecutive varus collapse). In the cement-augmented specimens, implant migration and femoral neck shortening were significantly dependent on bone mineral density (BMD), with higher values in osteoporotic bones. There was a correlation between failure load and BMD in cement-augmented specimens.Conclusion
In screw-anchor fixation of unstable femoral neck fractures, bone-cement augmentation seems to show no additional advantages in regard to stiffness, rotational stability, implant migration, resistance to fracture displacement, femoral neck shortening or failure load. 相似文献9.

Aims
To assess current national practice in the management of severe open tibial fractures against national standards, using data collected by the Trauma and Audit Research Network.Materials and methods
Demographic, injury-specific, and outcome data were obtained for all grade IIIB/C fractures admitted to Major Trauma Centres in England from October 2014 to January 2016.Results
Data was available for 646 patients with recorded grade IIIB/C fractures. The male to female ratio was 2.3:1, mean age 47 years. 77% received antibiotics within 3?h of admission, 82% were debrided within 24?h. Soft tissue coverage was achieved within 72?h of admission in 71%. The amputation rate was 8.7%. 4.3% of patients required further theatre visits for infection during the index admission. The timing of antibiotics and surgery could not be correlated with returns to theatre for early infection. There were significant differences in the management and outcomes of patients aged 65 and over, with an increase in mortality and amputation rates.Conclusions
Good outcomes are reported from the management of IIIB/C fractures in Major Trauma Centres in England. Overall compliance with national standards is particularly poor in the elderly. Compliance did not appear to affect rates of returning to theatre or early infection. Appropriately applied patient reported outcome measures are needed to enhance the evidence-base for management of these injuries. 相似文献10.

Purpose
Antegrade intramedullary nailing is an alternative for humeral shaft fracture treatment. This surgical technique can be especially demanding in some fracture patterns, leading to problems like malunion and non-union. The purpose of our study is to demonstrate that the use of a nail with cerclage wires could be a safe procedure that facilitate reduction, specially in fractures with abduction of the proximal fragment.Materials and methods
Fifty-six patients were included, from January 2007 to March 2016. In this cohort forty-two patients were females and eighteen males; mean age was sixty-seven (32–89). The fractures were reduced using a cerclage wire through a small lateral or anterior approach, then, antegrade intramedullary nailing was performed. Fracture healing was established by clinical and radiographic evaluation. Shoulder function was assessed using the Constant Score.Results
Fifty-three patients healed (94.6%) adequately. Two patients developed a non-union (3.5%). One patient developed an infection (1.8%). Transient radial nerve palsy was observed in two patients (3.5%). The mean Constant Score at the end of the study was 70 points (range from 34 to 98 points).Conclusions
Surgical treatment of humeral shaft fractures with cerclage wire and intramedullary nailing is a safe technique to improve fracture reduction. The use of cerclage wires leads to better bone contact while minimizing malunions. The rate of non-union in our study is lower than the rate reported in the literature for humeral shaft fractures treated by intramedullary nailing alone. 相似文献11.
Introduction
Multitrauma patients suffering hindfoot fractures, including calcaneal and talar fractures, often result in poor outcomes. However, less is known about the outcomes following midfoot fracture in the mutitrauma population. This study aims to describe the epidemiology of midfoot fractures in multitrauma patients and to compare the outcomes of midfoot and hindfoot fractures in this population.Methods
Data about multitrauma patients (Injury Severity Score >12) sustaining a unilateral midfoot or hindfoot fracture were obtained from the Victorian Orthopaedic Trauma Outcomes Registry (VOTOR) and from retrospective review of medical records at a major trauma centre. Further outcome data were obtained via a survey using the American Academy of Orthopedic Surgeons Foot and Ankle Score (AAOS FAS) and the 12-item Short Form Health Survey (SF-12).Results
122 multitrauma patients were included; 81 with hindfoot fractures and 41 with midfoot fractures. The median ISS (IQR) was 22 (17–29) and 27 (17–24) for the hindfoot and midfoot groups, respectively (p?=?0.23). Hindfoot and midfoot fractures were commonly associated with intracranial injuries (80.3%), spine injuries (60.7%), ipsilateral lower extremity injuries (24.6%) and pelvic injuries (16.4%). The mean (SD) time to follow up was 4.5 (±2.7) years. There were no differences in mean SF-12 physical (37.97 vs 35.22, p?=?0.33) or mental (46.90 vs 46.67, p?=?0.94) component summary scores between the groups. There were no differences in mean AAOS FAS standard scores (69.3 vs 69.1, p?=?0.97) or shoe comfort scores (median 40 vs 40 p?=?0.18) between the groups.Conclusion
Functional outcomes in multitrauma patients with midfoot or hindfoot fractures were comparable. These findings suggest that midfoot fractures should be treated with the same degree of due diligence as hindfoot fractures in the multitrauma patient. 相似文献12.
Introduction
The reported rate of nonunion of distal femoral fractures varies in the literature. Several risk factors for nonunion following lateral locked plating (LLP) have been described. We aimed to study the rate of nonunion, and risk factors thereof, in a Swedish population where fragility fractures are common. A secondary aim was to study risk factors for reoperation for any cause.Patients and Methods
We retrospectively reviewed the hospital files and radiographs of all adult patients admitted to our institution with a distal femoral fracture, from 2004 through 2013. In cases treated with LLP, medical comorbidities, fracture characteristics and implant characteristics were analysed as potential risk factors for nonunion, defined as any surgical intervention to improve healing.Results
There were 8 cases (4%, 95%CI: 1.8–8.1%) of nonunion in 191 fractures treated with LLP. Patients with nonunion were younger: 62 vs. 81 years (p?=?0.009) and more commonly had open fractures: 38% vs. 9% (p?=?0.034). No patient 80 years or older had a surgical intervention for nonunion. Lower age was independently associated with reoperation for any cause, but not for nonunion.Discussion
The low rate of nonunion in this study is probably due to the fact that we present data from a complete cohort from a geographic catchment area. Referral centres with a high proportion of young patients with high-energy injuries, may be better suited for studies on risk factors for nonunion, due to higher statistical power. However, results from such institutions may not be generalizable to the more common low-energy fractures. 相似文献13.

Background
Ankle fractures are extremely common and represent nearly one quarter of all lower-limb fractures. Techniques for fixation of displaced fractures of the lateral malleolus have remained essentially unchanged in recent decades. The current gold standard of treating unstable fractures is with open reduction and internal fixation (ORIF), using plates and screws construct. This study evaluates the use of fibula intramedullary nailing based on minimal invasive surgical approach.Methods
Thirty-nine cases treated with fibula intramedullary nailing between the years 2014–2016 were retrospectively studied. A fibular nail was utilized for the treatment of various ankle fractures either as the sole method of fixation or combined with another method. Patient charts were reviewed for fracture patterns, comorbidities, quality of reduction, complications and additional surgeries.Results
Out of 39 cases in the study cohort, 37 were closed fractures while 2 had an associated medial malleolus open injury. According to Weber classification of lateral malleolus fractures, 20 cases were type B, 18 cases type C, and one case of a pathologic fracture type B like fracture.Quality of reduction was based on previously published criteria. It was determined to be good in 32 cases, fair in 5 cases and poor in 2 cases that were revised intraoperatively to plate fixation.Overall no systemic complications occurred. Eight patients have undergone additional surgeries, namely hardware removals. In two cases, the nail was later revised to a different fixation method: one case to a plate, due to secondary displacement at 2 weeks, and one to an intramedullary tibiotalocalcaneal arthrodesis secondary to hardware failure and Charcot neuroarthropathy.Conclusion
Intramedullary fibular nail offers a satisfactory and safe procedure to establish good reduction and fixation of lateral malleoli fractures. It may be considered as treatment of choice for patients with soft tissue problems due to its minimal invasive approach. The current study shows that while good fracture reduction can be achieved, without major complications, more than fifth of patients, required secondary procedures, mainly hardware removals.Level of evidence: Level IV 相似文献14.
Objective
Symptomatic distal interlocking screws in retrograde femoral nailing are common due the difficulties of imaging the trapezoidal femur. Screws appearing to have appropriate length on imaging may possibly be prominent, creating symptoms. Screw trajectory may influence the degree of this radiographic error. We hypothesize that external rotation of screw trajectory will increase measurement error of screw length.Design
Retrospective.Setting
Urban Level I Tertiary Trauma Center.Participants
283 patients with Computer Tomography (CT) scans of the native knee were retrospectively identified. Simulation was done of the trajectory of an interlock at 20?mm and 40?mm proximal to the nail entry point, which represent common screw positions associated/not associated respectively, with removal. The distance between the radiographic medial cortex and the tip of the transverse screw was calculated (D). The angle (Ψ) between the transverse trajectory and a modified trajectory aimed at the most medial cortex to avoid radiographic measurement error was calculated. Geometric modeling was utilized to calculate the measurement error (D) in the event of accidental external rotation. The angle of the medial slope was also measured (Θ).Intervention
Review of CT imaging of normal distal femora.Main Outcome Measurements
CT measurements of distal femora.Results
The mean distance (D) at 20/40?mm was 4.21 [95%CI 4.02–4.402] and 2.03?mm [95%CI 1.78–2.83], respectively (p?<?0.0001). The mean angle (Ψ) between the transverse and modified trajectory at 20/40?mm was 12° [95%CI 11.5–12.5] and 9.60° [95%CI 9–10.2], respectively (p?<?0.0001). External rotation by a similar amount nearly triples the measured difference (D). The measured medial slope was significantly increased as screws were placed more proximal (Θ20 mm 46.5 vs Θ40 mm: 48.7?°, p?<?0.00001).Conclusion
The distance between the perceived medial cortex and the tip of the most transverse screw is 4.21?mm and could account for painfully prominent screws. In more proximal screws this distance is decreased. Internal rotation of the screw trajectory 12° can reduce this distance (D), which has implications in nail design. External rotation, amplifies this difference nearly three-fold. Surgeons should avoid external rotation of the aiming arm to prevent prominent screws. 相似文献15.

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16.

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18.
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19.

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20.
