Abstract
Radial head and neck fractures represent up to 14% of all pediatric elbow fractures and can be a difficult challenge in the pediatric patient. In up to 39% of proximal radius fractures, there is a concomitant fracture, which can easily be overlooked on the initial standard radiographs. The treatment options for proximal radius fractures in children range from non-surgical treatment, such as immobilization alone and closed reduction followed by immobilization, to more invasive options, including closed reduction with percutaneous pinning and open reduction with internal fixation. The choice of treatment depends on the degree of angulation and displacement of the fracture and the age of the patient; an angulation of less than 30 degrees and translation of less than 50% is generally accepted, whereas a higher degree of displacement is considered an indication for surgical intervention. Fractures with limited displacement and non-surgical treatment generally result in superior outcomes in terms of patient-reported outcome measures, range of motion and complications compared to severely displaced fractures requiring surgical intervention. With proper management, good to excellent results are achieved in most cases, and long-term sequelae are rare. However, severe complications do occur, including radio-ulnar synostosis, osteonecrosis, rotational impairment, and premature physeal closure with a malformation of the radial head as a result, especially after more invasive procedures. Adequate follow-up is therefore warranted.

Abstract
PURPOSE To determine the effect of native tibia valga on intramedullary nail (IMN) fixation of tibial shaft fractures. METHODS Retrospective comparative cohort analysis of 110 consecutive patients with tibial shaft fractures undergoing IMN fixation at an urban level one trauma centre was performed. Medical records and radiographs were reviewed for demographics, tibia centre of rotation of angulation (CORA), nail starting point, incidence of varus malreduction, and nail/canal proportional fit. RESULTS Tibia valga (CORA of ≥ 3 degrees) was present in 37 (33.6%) patients. The anatomic nail starting point distance (in relation to the lateral tibial spine) was significantly greater in the tibia valga group (12.0 mm vs. 5.0 mm, mean difference: 7.1 mm, 95% CI: 5.8 to 8.3 mm, p < 0.0001). Varus malreduction was more common in the tibia valga group (10.8% vs. 1.4%, proportional difference: 9.4%, 95% CI: - 1.0 to 21.3%, p = 0.04). Varus malreduction in the tibia valga group was associated with a decreased nail width/inner canal width proportion on multivariate analysis (OR = 0.683, 95% CI: 0.468 to 0.995, p = 0.0004). CONCLUSION Native tibia valga is common, and the use of a standard coronal IMN starting point with poor nail fit can lead to iatrogenic varus malreduction. In patients with tibia valga, maximizing nail fit or utilization of a medial starting point should be considered.

Abstract
INTRODUCTION Treatment of severe open femoral fractures with retrograde intramedullary nailing, raises concerns of septic arthritis of the knee due to its intra-articular entrance point. There is little evidence concerning the safety of retrograde femoral nailing (RFN) usage in these cases, and what evidence there is does not necessarily include severe open fractures. Furthermore, the outcome of ballistic injuries treated in this manner and a comparison with antegrade femoral nailing (AFN), is yet to be established. The aim of this study was to examine the outcome of primary retrograde femoral nailing in high-grade open fractures and compare our results with similar fractures treated with AFN. PATIENTS AND METHODS A retrospective analysis of treated high-grade open femoral fractures, was performed at an academic level one trauma centre between 2006 and 2016. Included were all open femur shaft fractures treated with either RFN or AFN as primary fixation. We analysed both patient groups and compared outcomes including the infection rate, non-union rate and secondary interventions. Presence of knee pain and long-term function, was evaluated using the Short-Form 12 (SF-12) questionnaire. RESULTS Forty-nine patients with open femoral shaft fractures whose primary treatment was intramedullary nailing (IMN), were included in the cohort. Thirty patients were treated with RFN and 19 with AFN. No septic arthritis of the knee was detected in either group. One patient in the RFN group and two in the AFN had a deep surgical wound infection. Excluding reoperations for locking screw removal due to local irritation, the reoperation rate was 22% with two patients treated for non-union in the RFN group and two in the AFN. When comparing outcome measures, including SF-12 scores and the reported knee pain rates of AFN and RFN groups, no significant differences were observed. CONCLUSION Our study showed that retrograde femoral nailing as initial definitive treatment in high-grade open femoral shaft fractures, resulted neither in septic arthritis of the knee nor in an unacceptable infection rate. General outcomes regarding complications and reoperations, was similar to antegrade femoral nailing performed in our centre for similar injuries.

Abstract
Purpose Osteosynthesis has been recommended for treatment of Pauwels type III femoral neck fractures in young patients. However, no implant of choice has been reported so far. This study was conducted in order to compare the fixation stability of two conventional fixation methods with three different novel fixed angle devices in this type of fracture. Materials and Methods A total of 25 composite femurs (4th Generation Saw bone; Pacific Research Laboratories, USA) corresponding to human bone were used. Pauwels type III fracture type was uniformly reproduced. Specimens were fixed with a cannulated screw, cannulated screw with cable, and Intertan nail, dynamic hip screw, and IKEY nail. Measurement of failure loads and the rotational change of the femoral head fragment was performed for evaluation of fixation stability. Results All implants were compared with cannulated screw and dynmaic hip screw. No meaningful improvement was observed for the cannulated screw with cable compared with the cannulated screw and dynamic hip screw. Meaningful improvement in load-to-failure and y-rotation and z-rotation was observed for both the Intertan nail and IKEY nail compared with the cannulated screw. However, compared with the dynamic hip screw, only the IKEY nail showed improvement in the same profile but the Intertan nail did not. Conclusion Among novel fixed angle devices, meaningful improvement was observed for the IKEY nail compared with conventional implants. Strengths of this implant include biomechanical stability and simplicity of surgical technique, indicating that it may be another good option for osteosynthesis of Pauwels type III femoral neck fractures.

Abstract
Posterior wall fractures are the most common type of acetabular fractures. Treatment can be conservative or surgical. Operative treatment is indicated for acetabular fractures that result in hip joint instability and/or incongruity, as well injuries with incarceration of fragments of bone or soft tissue within the hip joint. Surgical treatment can range from open reduction and osteosynthesis to hip arthroplasty. Arthroscopy has recently been used as the main surgical technique or as a reduction aid. In this case a 26-year-old male with a fracture of the posterior wall who underwent a posterior miniinvasive approach, followed by hip arthroscopy. This allowed joint wash, removal of the loose body, confirmation of reduction and absence of intra-articular hardware. Excellent clinical and radiological results were obtained. This case demonstrates the advantage of using hip arthroscopy in assessment of fracture reduction, the absence of intra-articular hardware or fragments, as well as a less invasive approach.

Abstract
Objective To retrospectively analyze the short and long-term efficacies of O-arm-navigated percutaneous short segment pedicle screw fixation, with or without screwing of the fractured vertebra. Methods A total of 42 patients who underwent O-arm-navigated percutaneous short segment pedicle screw fixation for the treatment of thoracolumbar fractures from February 2015 to December 2018 were selected for analysis. The patients were divided into two groups according to the surgical intervention they received: Group A received percutaneous short segment pedicle screw fixation with screwing of the fractured vertebra and Group B received percutaneous short segment pedicle screw fixation without screwing of the fractured vertebra. Radiographic analysis included Cobb angles and percentage of anterior vertebral height (AVH%). Clinical functional outcomes were assessed using the visual analog scale (VAS) for back pain and the oswestry disability index (ODI) scores. Results No significant differences were observed in the operation time and intraoperative blood loss between the two groups (P > 0.05). The length of incision was statistically significantly different between the two groups (P < 0.05). There was no significant difference in Cobb angle and AVH% between the two groups before and after the surgery (P > 0.05). However, the Cobb angle and AVH% were both significantly larger in Group A than Group B at the final follow-up (P < 0.05). In terms of clinical outcomes, there were no statistically significant differences in VAS and ODI scores between the two groups (P > 0.05). Conclusion In the short term, both minimally invasive treatments were safe and effective in treating thoracolumbar fracture. Although there was significant difference between the two groups in Cobb angle and vertebral body height at the last follow-up, the difference was small. Therefore, these specific parameters will be an important outcome measure in further investigations.

Abstract
OBJECTIVE The purpose of this study was to retrospectively evaluate patients who had open reduction, external fixation and bone cement implantation of open calcaneal fractures. METHODS The records of 14 patients with open calcaneus fractures from January 2015 to January 2019 were reviewed retrospectively. Clinical evaluations consisting of AOFAS, MFS and EQ-5D VAS scores and radiological evaluations consisting of the height, width and length of the calcaneus as well as Bohler's and Gissane angle performed at 3 months, 1 year and the last follow-up postoperatively. Time to surgery, wound complications were recorded. RESULTS Our study sample consisted of 9 males and 5 females with a mean age of 38.5 ± 9.8 years and a mean follow-up of 31.4 ± 7.7 months. The mean period from injury to surgery was 5.4 ± 1.9 days and the mean duration of hospitalization was 13.2 ± 4.5 days. The AOFAS, MFS and EQ-5D VAS scores were 92.5 ± 10.3, 84.1 ± 9.7 and 86.4 ± 15.1 respectively at the final follow-up. The Bohler's angle increased from (12.9 ± 3.1)° preoperatively to (28.5 ± 6.3)° at the final follow-up (P < 0.001), with the Gissane's angle from (104.5 ± 9.7)° to (116.4 ± 8.9)° (P < 0.001). One patients (7.1%) developed pin infections and one patient (7.1%) suffered from dorso-lateral hindfoot hypoaesthesia. There was complete fracture healing without secondary loss of reduction in all cases. CONCLUSION External fixation with bone cement implantation is a valid alternative treatment for the management of displaced open calcaneal fractures with a low rate of complications.

Abstract
Objective To evaluate clinical and radiological outcomes including hindfoot alignment after plate vs intramedullary nailing (IMN) for distal tibia fracture and to define radiologic parameters that influence changes in hindfoot alignment. Methods Among 92 patients with distal tibia metaphyseal fractures treated from 2002 to 2015, 39 cases of intramedullary nailing and 53 cases of standard plate osteosynthesis were performed. Union rate and complication rate were compared in both groups. Radiographic measurements including hindfoot angulation, moment arm, calcaneal pitch angle, and Meary angle were evaluated at a minimum of 1‐year follow‐up. Hindfoot alignment changes after surgery were compared between both groups using student t‐test. Correlation and regression were analyzed between fracture alignment parameters and hindfoot alignment. Results All patients ultimately healed, with an average union period of 26 weeks in both groups. The AOFAS and VAS scores were not significantly different between the two groups. Complications were similar between the two groups. Hindfoot alignment angle, calcaneal pitch, and Meary angle showed no significant differences between the groups. The hindfoot moment arm increased with valgus in the IMN group. A low correlation was detected between angulation at the fracture site in the coronal view and hindfoot alignment (angulation and moment arm) changes (R = 0.38). A significantly high correlation was noted only between transverse rotation and hindfoot alignment changes (R = 0.79). Conclusions Rotation in the transverse plane notably influenced changes in hindfoot alignment. And this suggests that patients with distal tibia fracture should be closely monitored for hindfoot alignment changes caused by intraoperative transverse rotation regardless of the fixation method.

Abstract
INTRODUCTION The purpose of this study was to evaluate how the hospital course of minimally displaced LC1 fractures, with and without occult instability, compares with that of intertrochanteric femur fractures. PATIENTS AND METHODS Retrospective comparative cohort analysis at an urban level one trauma center of 40 consecutive patients with an isolated LC1 pelvic ring injury and 40 age/sex matched patients with an isolated intertrochanteric femur fracture was performed. Medical records and radiographs were reviewed for patient and injury characteristics, including demographics, displacement, time to surgery, ambulation, physical therapy (PT) clearance, hospital length of stay (LOS), and inpatient morphine milligram equivalents (MME). RESULTS The LC1 pelvic ring injury group included 26 (65%) patients with ≥ 10 mm of displacement on lateral stress radiographs. The unstable LC1 group, compared to the stable LC1 group, had a greater LOS (median difference (MD): 2 days, 95% confidence interval (CI): 1 to 4, p = 0.0004), longer time to ambulate 15 feet (MD: 1 day, CI: 1 to 2, p = 0.0002), longer time to clear PT (MD: 2 days, CI: 1 to 3, p = 0.0003), and more inpatient MMEs (MD: 386 MME, CI: 225.8 to 546.7, p = 0.0002). The unstable LC1 and intertrochanteric fracture groups had no detectable differences in LOS (p = 0.24), days to ambulate 15 feet (p = 0.46), days to clear PT (p = 0.95), and inpatient MMEs (p = 0.06). CONCLUSION Patients with minimally displaced unstable LC1 injuries had worse hospital courses than stable LC1 injuries and similar hospital courses as intertrochanteric femur fractures. These findings emphasize the associated morbidity of unstable LC1 injuries. LEVEL OF EVIDENCE Level III, Retrospective cohort study.

Abstract
Geriatrics continues to evolve as a specialty by adapting itself to increasingly older patients. Musculoskeletal injuries are common in these patients, who can maintain their physical capacities and autonomy for a long time, but whose bone solidness is frequently reduced by osteoporosis. Falls increase with age and because of certain medical conditions. Trauma in the geriatric population involves specific risks; thus, the treatment must be adapted not only to the fracture, but to the local conditions and the patient. Ankle injuries are particularly frequent in general traumatology but even more in geriatric traumatology. They can lead to complete loss of autonomy if the treatment is delayed and/or not adapted to the local conditions or the patient. The functional prognosis is brought into play, along with the patient's life due to loss of autonomy and general complications occurring in patients who are bed-ridden. The treatment of bimalleolar ankle fractures in older adults requires rigorous analysis at all points, which starts by evaluating the cutaneous status and viability of the soft tissues upon admission. The benefit-risk balance of the various treatment options will be assessed with the main goal being that patients recover their autonomy. This article will review this topic by answering 7 questions: 1) What are the distinctive features of elderly? Dependence on others, comorbidities, bone and soft tissue fragility are the main ones, explaining these high-risk situations and frequent complications. 2) When should a bimalleolar ankle fracture be treated surgically? The surgery must be done early, preferably within 8hours of the injury occurring, once the comorbidities have been controlled. The local conditions (skin and soft tissue damage) must be evaluated carefully as they determine the treatment. Errors are not allowed in these patients, who are often fragile and in precarious health. Definitive fixation is preferred if the skin status allows it, but one must keep temporary external fixation in mind as an option. 3) Is there still a role for conservative treatment of displaced fractures? This will produce good results when it is well done; however, the indications are rare and must be selected carefully. The main risks are secondary displacement and skin lesions inside the cast, which are sources of infection. 4) Is fixation with anatomical locking plates an advance? This is definitely an advance for these fragility fractures, which are often comminuted, as it allows return to weight bearing in certain conditions. However, the implantation rules must be followed exactly, and it is preferable to use thinner plates. 5) Does transplantar Steinmann pin fixation still have a role? It has few indications, limited to salvage situations (catastrophic local conditions, very poor general condition). External tibiocalcaneal fixation, alone or in combination, is a better option. 6) Is immediate transarticular fixation with a retrograde or antegrade locked nail a reasonable option? Fixation can be done by retrograde nailing or antegrade nailing. It is proposed to patients who are not very autonomous with a poor cutaneous status and/or severe osteoporosis. It is preferable to transplantar nailing. 7) Is immediate protected weight bearing, with or without fixation, possible? This can be considered on a case-by-case basis depending on the extent of the trauma, patient compliance and treatment carried out. LEVEL OF EVIDENCE: V, Expert opinion.

Abstract
BACKGROUND We report our preliminary results using a single approach, the mirror Judet approach, for patients with both ipsilateral scapula and multiple rib fractures. METHODS Five consecutive patients [median age: 56 years (range: 44 ~ 60)] with ipsilateral scapula and multiple rib fractures that met the surgical indications were retrospectively reviewed. A single approach, the mirror Judet approach, was used for surgical stabilization of the scapula and targeted rib fractures. Thoracoscopic surgery was performed first for management of associated lung lesions and marking the targeted rib. All patients received the same rehabilitation protocol and a minimum 12-month follow-up. RESULTS All surgically-fixed fractures eventually united without malunion. No complaints of intercostal neuralgia, infection, or other complications were seen. The mean range of motion in the injured shoulder returned to at least 90% of the contralateral side range. The mean Disabilities of the Arm, Shoulder, and Hand score at the 12th month was 2.0 (range: 0-7). All patients were able to return to their previous work. CONCLUSION The mirror Judet approach allows for the surgical stabilization of the ipsilateral scapula and multiple rib fractures using the same approach and provides acceptable functional outcomes in well-selected patients.

Abstract
Background Combined medial and lateral plate fixation is recommended for complex tibial plateau fractures with medial fragments or no cortical bone contact. Although such fixation is adequate to resist forces during range of motion, it may be insufficient to support immediate postoperative weightbearing. Here, we analyzed displacement, stiffness, and fixation failure during simulated full weightbearing of bicondylar tibial plateau fractures treated with combined medial and lateral locking plate fixation. Methods We used 10 fresh-frozen adult human cadaveric tibias and mated femurs. Osteotomies were performed with an oscillating saw and cutting template to simulate an AO Foundation and Orthopaedic Trauma Association (AO/OTA) 41-C2 fracture (simple articular, multifragmentary metaphyseal fracture). Specimens were anatomically reduced and stabilized with combined medial and lateral locking plates (AxSOS, Stryker, Mahwah, NJ). Specimens were loaded axially to simulate 4 weeks of walking in a person weighing 70 kg. The specimens were cyclically loaded from 200 N to a maximum of 2800 N. Then, if no failure, loading continued for 200,000 cycles. We measured displacement of each bone fragment and defined fixation failure as ≥5 mm of displacement. Construct stiffness and load at failure were calculated. Categorical and continuous data were analyzed using Chi-squared and unpaired t-tests, respectively. Results Mean total displacement values after 10,000 loading cycles were as follows: lateral, 0.4 ± 0.8 mm; proximal medial, 0.3 ± 0.7 mm; distal medial, 0.3 ± 0.6 mm; and central 0.4 ± 0.5 mm. Mean stiffness of the construct was 562 ± 164 N/mm. Fixation failure occurred in 6 of 10 specimens that reached 5 mm of plastic deformation before test completion. In the failure group, the mean load at failure was 2467 ± 532 N, and the mean number of cycles before failure was 53,155. After test completion, the greatest displacement was found at the distal medial fracture site (2.3 ± 1.4 mm) and lateral fracture site (2.2 ± 1.7 mm). Conclusions Although combined medial and lateral plate fixation of complex tibial plateau fractures provides adequate stability to allow early range of motion, immediate full weightbearing is not recommended.

Abstract
OBJECTIVE Pelvic and acetabular fractures are common orthopedic diseases, and this research was to investigate the therapeutic effects of pararectus and Stoppa approaches in treating complex pelvic acetabular fractures. METHODS The clinical information of patients with pelvic and acetabular fractures treated surgically in Lu'an Hospital of Chinese medicine, China from January 2016 to April 2020 was analyzed. There were 30 cases each in the transabdominal pararectus approach and modified Stoppa approach groups. The operation time, incision length, blood loss, and postoperative complications of both groups were recorded according to the Merle d'Aubigné-Postel hip score. The recovery of hip function was evaluated 6 months after surgery, and the clinical and therapeutic efficacies of the two groups were compared. RESULTS The patients were followed up for 6-7 months (average, 6.5 months). The average operation time, incision length, and blood loss in the pararectus and Stoppa approach groups were 180 ± 41.105 min, 8.667 ± 1.373 cm, 259.667 ± 382 mL and 202.667 ± 32.793 min, 11.600 ± 1.958 cm, and 353.667 ± 590 mL, respectively. The satisfactory rate of fracture reduction, excellent and good rate of hip function score, and incidence of complications were 28/30, 27/30, 1/30 and 25/30, 25/30, 3/30, respectively. There were significant differences in operation time, incision length, and blood loss between the two groups (p < 0.05). However, there was no significant difference in the excellent and good rate of hip function score, fracture reduction satisfaction, and complication rate between both groups (p > 0.05). CONCLUSIONS The pararectus approach can reveal the better anatomical structure of the pelvis and acetabulum, such as the corona mortis and quadrilateral plate, for conducive fracture reduction and fixation. It can also effectively shorten the length of the incision, reduce operative blood loss, and shorten the operation time. It is a better choice for the clinical treatment of complex pelvic and acetabular fractures.

Abstract
INTRODUCTION AND OBJECTIVES New generation cephalomedullary nails are, currently, widely used for the treatment of trochanteric proximal femoral fractures. This study aims to compare the midterm outcomes and complication rates in patients with unstable 31A2 fractures treated with two different lengths of nails. MATERIALS AND METHODS Retrospective study including 123 pertrochanteric proximal femoral fractures 31A2 treated with Gamma3 nail® between January/2017 and January/2019. 19 patients were excluded, resulting in a total of 104 patients with a minimum follow-up of 1 year. Two groups, Long Dynamic Gamma3 Nail (LGN) and Short Static Gamma3 Nail (SGN), with 52 patients each were compared. Mean age was 81 years (range 50-99), being 78% female. Preoperative variables included: age, medical comorbidities, mobility, anesthetic risk, associated fractures, hemoglobin and hematocrit values. Postoperatively, functional and radiological results, quality of life, hemoglobin and hematocrit concentration, transfusion requirements, mobility, and pain were evaluated. Additionally, perioperative complications were also analyzed, such as malunion, non-union, infection rates, cut-outs, and peri-implant fractures. RESULTS A correct radiological fracture reduction was obtained in 73% of the cases (73% SGN/74% LGN). Two patients in LGN group had intraoperative complications (greater trochanter fractures). 38% of the patients with LGN presented nail tip impaction upon the distal anterior femoral cortex, associated with anterior knee pain. Blood loss and operative time was statistically different between groups. Despite the previous, no differences in clinical outcomes and quality of life were found. CONCLUSIONS The present study comparing two lengths of the Gamma3 Nail in 31A2 fractures showed no overall differences in clinical and radiological outcomes, and complication rates. However, the use of LGN was associated with a statistically significant higher blood loss and operative time, and a tendency for increased need for transfusion, and anterior knee pain and reoperation rate. Therefore, we recommend the use of locked SGN in the treatment of 31A2 fractures.

Abstract
Aims Assessment of bone mineral density (BMD) with dual-energy X-ray absorptiometry (DXA) is a well-established clinical technique, but it is not available in the acute trauma setting. Thus, it cannot provide a preoperative estimation of BMD to help guide the technique of fracture fixation. Alternative methods that have been suggested for assessing BMD include: 1) cortical measures, such as cortical ratios and combined cortical scores; and 2) aluminium grading systems from preoperative digital radiographs. However, limited research has been performed in this area to validate the different methods. The aim of this study was to investigate the evaluation of BMD from digital radiographs by comparing various methods against DXA scanning. Methods A total of 54 patients with distal radial fractures were included in the study. Each underwent posteroanterior (PA) and lateral radiographs of the injured wrist with an aluminium step wedge. Overall 27 patients underwent routine DXA scanning of the hip and lumbar spine, with 13 undergoing additional DXA scanning of the uninjured forearm. Analysis of radiographs was performed on ImageJ and Matlab with calculations of cortical measures, cortical indices, combined cortical scores, and aluminium equivalent grading. Results Cortical measures showed varying correlations with the forearm DXA results (range: Pearson correlation coefficient (r) = 0.343 (p = 0.251) to r = 0.521 (p = 0.068)), with none showing statistically significant correlations. Aluminium equivalent grading showed statistically significant correlations with the forearm DXA of the corresponding region of interest (p < 0.017). Conclusion Cortical measures, cortical indices, and combined cortical scores did not show a statistically significant correlation to forearm DXA measures. Aluminium-equivalent is an easily applicable method for estimation of BMD from digital radiographs in the preoperative setting. Cite this article: Bone Joint Res 2021;10(12):830–839.

Abstract
In order for a radiologist to create reports that are meaningful to facial reconstructive surgeons, an understanding of the principles that guide surgical management and the hardware employed is imperative. This article is intended to promote efficient and salient reporting by illustrating surgical approaches and rationale. Hardware selection can be inferred and a defined set of potential complications anticipated when assessing the adequacy of surgical reconstruction on postoperative computed tomography for midface, internal orbital, and mandible fractures.

Abstract
Purpose After intramedullary nailing of tibial shaft fractures using an infrapatellar/transtendinous approach, several patients suffer anterior knee pain. We suspect that the approach is associated with soft tissue scars and the development of a postoperative patella baja. The goal of the study is to investigate whether the development of patella baja is associated with worse subjective outcomes. Methods We retrospectively analyzed all patients in our orthopedic trauma department between 2011 and 2020 who underwent tibial fracture fixation via intramedullary nailing via an infrapatellar/transtendinous approach. Pre- and postoperative lateral knee x-rays were evaluated by measurement of the Insall-Salvati Index, and nail tip position. All patients were asked to answer the self-assessment Kujala questionnaire and Lysholm questionnaire. Results We included 78 patients (age: 44 ± 18 years) with a minimum follow-up of 12 months. Mean follow up was 59 ± 25 months. We included 50 male and 28 female patients. Patella baja detected by Insall-Salvati Index could be observed in 8 (10.3%) patients. Patients with patella baja showed significant worse function measured by the Kujala score 54 ± 18 vs. 80 ± 14 (p < 0.01). Likewise, Lysholm score did show significant differences between both groups (60 ± 24 vs. 86 ± 11; p < 0.01). Nail tip position was not associated with worse subjective function. Conclusions Patella baja in patients after tibial intramedullary nailing via an infrapatellar/transtendinous approach, is associated with worse subjective function and increased pain.

Abstract
INTRODUCTION Although intraoperative imaging is important for assessing the quality of several steps during fracture fixation, most trainees and surgeons have received little formal education on this topic and report they learn "on the job" and "through practice". A planning committee of orthopedic trauma surgeons was established to design a curriculum using "backward planning" to identify patient problems, identify gaps in surgeons' knowledge and skills, and define competencies as a framework for education in order to optimize patient care. MATERIALS AND METHODS The committee defined 8 competencies related to intraoperative imaging, with detailed learning objectives for each one (e.g. select the imaging modality, set up the operating room). An interactive, case-based half-day seminar to deliver these objectives for 2-D and 3-D intraoperative imaging during the fixation of common fractures was designed. The seminar was delivered in several locations worldwide over a 6-year period and evaluation and assessment data were gathered online. A full-day procedures course was added and delivered 6 times to address the skills component of competencies. RESULTS 17 seminars and 6 courses were delivered and attended by an average of 26 and 17 participants respectively (ranges 13-42 and 13-20). Pre-event gap analysis and assessment question scores confirmed needs and motivation to learn in all events. 97% of the 442 seminar participants and 98% of the 100 course participants would recommend the events to colleagues. An average of 88% and 90% respectively learned something new and plan to use it in their practice (range 63%-100%). Commitment to change (CTC) statements showed intended practice improvements related to all competencies. DISCUSSION The large percentages of high impact ratings for all events suggest the content met the needs of many participants. Post-event reduction in gap scores and an increase in the desired level of ability for most competencies suggests the content addressed many gaps. CONCLUSIONS Case-based, interactive seminars and courses addressing knowledge, skills, and attitudes to optimize the use of intraoperative imaging during the fixation of common fractures help address unmet educational needs for trainees and complements existing formal training.

Abstract
BACKGROUND Posterior fixation without fusion can treat thoracolumbar and lumbar traumatic fractures effectively in certain cases. However, whether patients benefit from implant removal and the correlation between the range of motion (ROM) of the involved segments and the removal time have not been determined. METHODS From 2018 to 2020, we retrospectively reviewed data of patients with AO spine type A or B thoracolumbar or lumbar traumatic fractures who underwent implant removal. A total of 17 patients (group A), 21 patients (group B), and 12 patients (group C) underwent implant removal after the index surgery within 12 months, between 12 and 24 months, and over 24 months, respectively. Clinical and radiological outcomes, including visual analog scale for back pain, patient satisfaction, Oswestry disability index, and EuroQol 5 dimensions questionnaire, for quality of life and segmental ROM were analyzed. RESULTS The average follow-up time was 9.1 ± 5.7 months after implant removal. There were no significant differences in visual analog scale and patient satisfaction among the 3 groups at the same observation time point. Among the 3 groups, patients in group A gained the lowest Oswestry disability index and highest EuroQol 5 dimensions questionnaire scores after removal and at the final follow-up. The best ROM was obtained in group A followed by groups B and C (11.5° ± 6.2°, 5.5° ± 1.6°, and 2.4° ± 0.6°, respectively). CONCLUSIONS Immobilization of the involved segments over 24 months may lead to loss of ROM. Regained segmental ROM is correlated negatively with implant removal time, and removal within 12 months promises a better ROM and quality of life.

Abstract
Background The aim of this study is to evaluate the postoperative stability of zygomaticomaxillary complex (ZMC) fractures according to the number of fixation sites and to investigate the direction of postoperative displacement of the unfixed part of the fractured segment. Methods This study was retrospectively performed on 38 patients who were treated by open reduction and internal fixation of ZMC fractures and were taken postoperative computed tomography (CT) between February 2012 and July 2019. The patients were classified into 3 groups: 1-point fixation, 2-point fixation, 3-point fixation according to the number of fixations. The postoperative displacement of the fractured segment was evaluated by the superimposition between postoperative CT and follow-up CT, and the postoperative stability according to the fixation sites was investigated through the amount of postoperative displacement. In addition, it was investigated in which direction the location of the fractured segment was changed in the unfixed fractured segment according to the fixation sites. Results The amount of postoperative displacement of the fractured segment was 0.75 ± 1.18 mm on average. In the postoperative displacement of the distal area according to the number of fixation of the fracture, there was no statistically significant difference in the amount of displacement of the fracture (p = 0.574). As for the direction of the change in the location of the fractured segment, 12 patients among 38 patients with the change in the location of the fractured segment were investigated, and the displacement in the medial direction (n = 11, 91.67%) was the most common in all three fixation methods. Conclusion In patients with a ZMC fracture who were treated by open reduction and internal fixation, the number of fixations did not make the difference in the postoperative displacement of the fracture. In addition, the fractured segment mainly changes in the medial direction after surgery, and this fact can be used as a reference for the reduction direction during surgery for the stable prognosis.

Abstract
OBJECTIVE To compare clinical efficacy between anatomical locking plate (ALP) and ordinary steel plate (OSP) in treating closed calcaneal fractures with SandersⅡ and Ⅲ. METHODS From May 2016 to May 2018, 68 patients with closed Sanders typeⅡ and Ⅲ calcaneal fractures were retrospectively analyzed, and were divided into anatomical locking plate group (ALP group) and ordinary steel plate group (OSP group) according to two kinds of plate fixation, and 34 patients in each group. In ALP group, there were 21 males and 13 females aged from 20 to 63 years old with average of (35.16±8.45) years old; 14 patients were typeⅡand 20 patients were type Ⅲaccording to Sanders classification;treated with ALP. In OSP group, there were 20 males and 14 females aged from 19 to 63 years old with average of (35.05±8.39) years old;19 patients were typeⅡand 15 patients were type Ⅲ according to Sanders classification;treated with OSP. Operative time, intraoperative blood loss and complications between two groups were observed and compared;preoperative and postoperative Böhler angle and gissane angle were also compared;American Orthopaedic Foot & Ankle Society (AOFAS) ankle and hind foot scores, foot and ankle disability index (FADI) scores were applied to evaluate clinical effect. RESULTS All patients were followed up from 11 to 14 months with an average of (12.06±0.81) months. There were no statistical differences in opertive time, intraoperative blood loss, incision infection and refracture rate in complications between two groups (P>0.05);while there was significant difference in the number of screw loosening (P<0.05). Böhler angle and Gissane angle in ALP group at 6 and 12 months after opertaion were higher than that of OSP group (P<0.05), and the degree of improvement of Böhler angle and Gissane angle in ALP group were also higher than that of OSP group (P<0.05). Postopertaive AOFAS score and FADI score at 6 and 12 months in ALP group were higher than that of OSP group (P<0.05), while no statistical difference in AOFAS grading between two groups(P>0.05). CONCLUSION Compared with OSP, ALP in treating SandersⅡ and Ⅲ calcaneal fractures could achieve better therapeutic effect, avoid screw loosening, reduce complications, and improve limb function in further.

Abstract
Injuries to the subaxial cervical spine are increasing and have an increased neurological risk compared to the thoracic and lumbar spines. The current treatment recommendations according to the therapeutic recommendations of the Spine Section of the German Society for Orthopedics and Trauma Surgery (DGOU) as well as the S1 guidelines of the German Trauma Society (DGU) are presented. This second part of the article describes the correct indications and treatment planning for injuries to the cervical spine. Based on the AOSpine classification for subaxial cervical spine injuries, decisions can be made about conservative or surgical treatment as well as individual details of the treatment. The underlying principles of treatment are relief of neurological structures, restoration of stability and reconstruction/preservation of the physiological alignment.

Abstract
Purpose To compare the CFR-PEEK plates with conventional plates in fracture fixation with regards to clinical and radiological outcomes and complications. Methods A systematic literature search was conducted in four online databases independently by two reviewers using the Cochrane methodology for systematic reviews. The identified relevant studies were assessed against predetermined inclusion/exclusion criteria. Independent data extraction and assessment of risk of bias and study quality was carried out. Results Nine studies (patient n = 361) out of 6594 records were included for analysis: 2 RCTs (n = 63), 3 prospective cohort studies (n = 151), and 4 retrospective cohort studies (n = 147). Studies were grouped per anatomic area of fixation. Four studies (n = 200) examined fixation of proximal humerus fractures. Two studies (n = 74) examined fixation of distal radius fractures. Two studies (n = 53) assessed outcomes of fixation of distal femur fractures. One study (n = 87) assessed the outcomes of fixation of ankle fractures. All nine studies reported very high union rates (from 91% in distal femur to 100% in upper limb) for the CFR-PEEK plate groups and low complication rates. There was no significant difference in clinical outcomes, and rate of complications as compared to the conventional plate groups. Conclusion CFR-PEEK plates have high union rates in extremity fracture fixation similar to conventional plates with comparable good clinical outcomes and a very low and comparable rate of complications. Considering their advantages, CFR-PEEK plates seem to be valid alternative to conventional plating.

Abstract
PURPOSE To compare functional and radiological outcomes of transverse patella fractures treated with tension band wiring using either two 4.5 mm cannulated screws or Kirshner wire. METHODS This is a non-blinded prospective randomized study comprising of two groups (n = 30 each) with closed transverse patella fractures treated with tension band wiring using Kirschner wire (K wire group) and two 4.5 mm cannulated screws (CCS group). Outcomes measured were radiological union, Knee Society score, range of motion and post-operative complications. RESULTS The CCS group showed a statistically significant higher range of motion than K wire group for each follow up (p < 0.001 in flexion and p < 0.005 in extension). A statistically significant higher percentage of patients in the CCS group showed signs of union at 6th and 12th post-operative week (p = 0.001 and 0.011 respectively) but no difference at 24th post-operative week (p = 0.313). The rate of hardware complications was significantly higher in K wire group (p = 0.001). No significant difference was noted in in the Knee society score and post-operative complications between the groups. CONCLUSION This study concludes that the fixation of closed transverse patella fractures using two 4.5 mm cannulated screws is allows a faster rate of union, a better knee range of motion and lesser hardware complications as compared to Kirschner wires. However more studies with larger sample sizes and longer follow up are required.

Abstract
BACKGROUND Posterior wall fracture is the most common type of acetabular fracture, the traditional open reduction and fixation through the Kocher-Langenbeck approach required a large incision and extensive muscle and soft tissue dissection, resulting in more blood loss, more complications and delayed recovery after the operation. Hip arthroscopy has been widely used in clinical practice but rarely reported in acetabular fractures. CASE PRESENTATION We present the case of a 14-year-old boy with acetabular posterior wall fracture who was treated with hip arthroscopy reduction and fixation using anchors. He began to walk with partial weight-bearing assisted by double crutches, and returned to school with crutches at 3 days after surgery. Although hip arthroscopy is technically more demanding, it's an optimal choice for selected patients of acetabular fracture with the advantages of less invasive and faster postoperative recovery.

Abstract
BACKGROUND Current implants for clavicle fractures are known to cause poor cosmesis and irritation, which may require implant removal. Low-profile shape-memory staples provide an attractive alternative, but their biomechanical utility in clavicle reconstruction is unknown. We hypothesized that shape-memory reconstructions would be more compliant compared to traditional constructs but would also outperform conventional plates during cyclic loading to failure. METHODS This study was performed with 36 synthetic clavicles and 12 matched pairs of cadaveric specimens. The synthetic study tested four reconstructions: a single superiorly placed staple (n = 6), a single anteroinferiorly-placed staple (n = 6), a 3.5 mm reconstruction plate (n = 12), and two orthogonally placed staples (n = 12). The cadaveric study tested three constructs: reconstruction plate (n = 8), two orthogonal staples (n = 8), and a 2.7 mm reconstruction plate combined with a superior staple (n = 8). Non-destructive 4-point bending, compression, and torsion assays were performed prior to destructive cantilever bending and cyclic torsion tests. FINDINGS The single staple and double staple groups demonstrated significantly decreased resistance to bending (p < 0.001) and torsion (p ≤ 0.027) when compared to reconstruction plate groups. The double staple group sustained significantly fewer cycles to failure than the reconstruction plate group in cyclic torsional tests (p = 0.012). The synthetic models produced higher stiffness and failure mechanisms that were completely different from cadaveric specimens. INTERPRETATION Shape memory alloy implants provided inadequate stiffness for clavicle fixation but may have utility in other orthopaedic applications when used as a supplementary compression device in conjunction with traditional plated constructs. Synthetic bones have limited capacity for modeling fragility fractures.

Abstract
PURPOSE OF REVIEW Fracture fixation aims to provide stability and promote healing, but remains challenging in unstable and osteoporotic fractures with increased risk of construct failure and nonunion. The first part of this article reviews the clinical motivation behind finite element analysis of fracture fixation, its strengths and weaknesses, how models are developed and validated, and how outputs are typically interpreted. The second part reviews recent modeling studies of the femur and proximal humerus, areas with particular relevance to fragility fractures. RECENT FINDINGS There is some consensus in the literature around how certain modeling aspects are pragmatically formulated, including bone and implant geometries, meshing, material properties, interactions, and loads and boundary conditions. Studies most often focus on predicted implant stress, bone strain surrounding screws, or interfragmentary displacements. However, most models are not rigorously validated. With refined modeling methods, improved validation efforts, and large-scale systematic analyses, finite element analysis is poised to advance the understanding of fracture fixation failure, enable optimization of implant designs, and improve surgical guidance.

Abstract
Background The purpose of this study was to compare shoulder outcomes and function after humeral shaft fractures treated with plates and screws vs. antegrade nailing. Methods A group of 27 patients treated with plates and a group of 30 patients (previously published) who had undergone antegrade locked intramedullary nailing, all with acute humeral shaft fractures, were retrospectively compared. Final shoulder range of motion (ROM), full shoulder ROM recovery rate, functional outcomes, residual pain, complications, and elbow flexion-extension range were also analyzed. Results There were a total of 57 patients: 27 cases in the plate (P) group and 30 in the nail (N) group (average age, 41.9 years).There were 66.7% men in group N and 63.0% in group P. The average age was 38 years (interquartile range [IQR] 28) in group N and 37 years (IQR 55) in group P. There were no differences in follow-up between groups, which averaged 28 months (IQR 7) in group P and 30 months (IQR 2) in group N (P = .385). There was no difference in both groups in elbow flexion-extension. Group P had a full shoulder ROM (66.6% vs. 40.0%; P = .02) and excellent Rodríguez-Merchán scoring (66% vs. 40.0%; P < .01), which was significantly higher than in group N. In group P, the Constant score was 95 (IQR 9). Conclusions Treatment with plates in this comparative study led to a better ROM in the shoulder and fewer complications. Loss of shoulder motion may be expected after humeral shaft osteosynthesis. However, the functional scores and the healing index can be good and excellent with both techniques.

Abstract
INTRODUCTION Basicervical femoral neck fracture is associated with high rates of failure due instability patterns, mainly collapse and rotational instability. The purpose of this study was to evaluate the clinical-radiological results of a group of patients with a bascervical proximal femoral fractures treated with Percutaneous Compression Plate (PCCP). MATERIAL AND METHODS Among 5817 patients with a hip fracture who were admitted in our hospital from January 2005 to December 2017, 234 factures (4%) were diagnosed of basicervical femoral fracture. 30 of them were treated with a PCCP, 22 women and 8 men, mean age was 81.2 years (63-94). Demographic and perioperative variables were collected. The patients were followed up at 1, 3 and 6 months clinically and radiologically. RESULTS There were no intra-operative complications and no conversions to open surgery. There was no early implant failure. No surgical wound infection was diagnosed. Crude mortality was 13% the first year and 87% were able to walk at the 6 months. The last follow-up x-rays revealed 97% fracture healing and the collapse at fracture site occurred in 4 hips. No instances of cut-out were observed. In one case, a fatigue failure of the lag screws of a PCCP plate was observed at 3 months from osteosynthesis. CONCLUSION PCCP is an appropriated implant for basicervical femoral neck fractures.

Abstract
AIMS Iatrogenic varus malreduction after intramedullary nailing of intertrochanteric fractures (wedge effect) may be more common than previously reported. The aim of study is to determine its incidence and to define easy fluoroscopic landmarks to recognize it intraoperatively. PATIENTS AND METHODS We included surgical procedures with residual varus malreduction and sufficient intraoperative fluoroscopy images to assess an intraoperative anatomical reduction at the beginning of the procedure. Two intraoperative fluoroscopic landmarks were defined to assess varus in the anteroposterior view: the position of the greater trochanter (GT) related to the femoral shaft (medialized GT sign), and the position (superior, centre or inferior) of the guide wire in both the neck and the head of the femur (cross wire sign). We describe our current method of treatment to avoid this complication. RESULTS A total of 369 extracapsular hip fractures were treated using PFNA and Gamma 3 systems. We found 55 (14.9%) fractures with a varus malreduction. Six were underreduced and fixed in varus. Thirty-five (9.48%) were well reduced by closed reduction but suffered a iatrogenic varus displacement when introducing the nail. 31 were female; mean age was 86.6 (range 70-97). Mean postoperative head-shaft angle was 119,2° range (113°-123°). Mean TAD was 24,37 range (14-36 mm). CONCLUSION Wedge effect (iatrogenic varus displacement of a well reduced intertrochanteric fracture when introducing the nail) could occur in at least 10% of intertrochanteric fractures. The medialized GT and the "crossing wire sign" seem to be good predictors of iatrogenic varus malalignement.

Abstract
INTRODUCTION Open tibial shaft fractures present a challenge to the orthopedic surgeon, because they are common, have a high rate of complications and still have a controversial treatment. As a result of the high incidence of these fractures, the need of a definitive treatment and the unavailability of the intramedullary nail or a well-trained team, we developed this study to compare the effectiveness of the bridge-plating (BP) with the unreamed intramedullary nail (UIMN) in the treatment of open tibial shaft fractures. MATERIALS AND METHODS Eighty patients were included in a prospective, consecutive and random way and then randomized in two groups of treatment: unreamed intramedullary nail and bridge-plating. The primary outcomes were the reoperation rate and the Johner-Wruhs functional criteria. Secondary outcomes were complication rates, partial and total weight bearing time and bone consolidation time. We verified the existence of normality in the quantitative variables for the outcomes using the Kolmogorov-Smirnov test. The Chi-Square test was utilized to compare the methods according to the relative frequencies and the comparison between the methods regarding the average of the quantitative variables was done through the T-Student test. RESULTS Both the reoperation rates and the functional criteria of Johner-Wruhs showed no difference between the two groups. The exposure time and the total surgical time were longer in the UIMN group, however the consolidation time, partial weight bearing time and total weight bearing time did not show significant difference. A significant difference was found between the groups in the implant failure rate, in favor of UIMN, the angular malalignment was another secundary outcome that showed a non significant difference in favor of UIMN. CONCLUSIONS We concluded that both methods were effective for the treatment of open tibia shaft fractures, however, the implant failure rate was higher in the bridge plate group.

Abstract
INTRODUCTION Excellent results have been published in the treatment of the trochanteric fractures in the elderly with cephalomedullary nails or compression hip screws but not free of complications. The perforation of the lag screw through the superior cortex of femoral neck or head followed by rotation and varus collapse of the head-neck fragment, also known as cut-out, is one of them. Probably total hip arthroplasty is the most common solution, but there is no systematic technique for treatment. The objective of this study is to evaluate the results obtained in the treatment of this complication using a variable angle femoral plate. MATERIAL AND METHODS This retrospective study concerns patients over 65 years with peritrochanteric fractures treated with cephalomedullary nail with cut-out failure solved by re-osteosyntesis with variable angle femoral plate between 1st January 2000 and 31 st December 2017. The series includes 29 patients, 26 women and 3 men with average age 87,3. Patients were followed up clinically and radiologically at regular intervals until fracture consolidation at least 9 months. RESULTS No patients died at the first 9 months after surgery. Fracture mean consolidation has occurred in all patients in 14th weeks (6-20). Operative time was 93,2 minutes (62-129) including removal of nail. No intraoperative complications were observed. Five patients experienced medical complications and two had a superficial wound infection. The mean tip-apex distance (TAD) was 5mm (2-7mm). The neck-shaft angle was 127 degrees. The mean valgization achieved was 32 degrees (15-40). Only one patient needed a second revision surgery due to aseptic hip joint subluxation after 8 weeks of the surgery solved with total hip arthroplasty. CONCLUSIONS The use of variable angle femoral plate in the cut-out treatment is an attractive option which allows the valgization of the fracture to virtually physiological limits and the placement of the cephalic screw in the most sutiable position with good outcomes and few complications.

Abstract
INTRODUCTION Fractures of the proximal humerus are frequent and are widely studied with regards to their treatment indications. The aim of this article is to establish a correlation between the size of the epiphyseal fragment in fractures of the proximal humerus and the probability of loss of reduction after a surgical procedure. METHODS A total of 47 surgically treated proximal humeral fractures were reviewed. Preoperative CT scans were used to evaluate the size of the epiphyseal fragment of the fracture. Postoperative X-rays were analyzed to assess complications, especially loss of reductions. Mean age was 61 years old (29-91 years). RESULTS In total, 42 shoulders were evaluated. The average size of the epiphyseal fragment was 38.3 mm (32-50 mm) the largest longitudinal length; and 19.9 mm (12-30 mm) the largest cross-sectional length. The most frequent complication observed was loss of reduction. The statistical analysis showed significance that patients with smaller cross-sectional size of the epiphyseal fragment presented more complications (p = 0.034), and based on the graph and ROC curve, a value of 15.5 mm was considered as the cutoff value for failure. CONCLUSION A cross-sectional length of the epiphyseal fragment of less than 15.5 mm indicates a higher probability of loss of reduction in fractures of the proximal end of the humerus after extra-medullary osteosynthesis.

Abstract
INTRODUCTION The aim of this study was to determine the feasibility of applying the MIPO technique with a helical-shaped plate in the treatment of humeral shaft fractures with proximal extension. PATIENTS AND METHODS We present an observational prospective study of patients with a humeral shaft fracture involving the proximal humerus fixed with a long proximal humerus polyaxial locking plate with an anterior curvature and helical shape (ALPS® Zimmerbiomet, Warsaw, Indianapolis, USA), using a MIPO technique. Between January 2017 and July 2020, 15 patients were treated at our institution. Proximally a 4-5 cm anterolateral transdeltoid approach was made. And distally, a 5-7 cm incision was made 4 cm proximal to the elbow crease. At each follow-up, radiographs were taken to evaluate fracture healing. Funtional scales were applied to evaluate clinical results. RESULTS Ten women and five men were included, with a mean age of 62 yo (range 26-86). All but one fracture healed uneventfully. The mean time to union was 28 weeks (range 12-48 weeks). Two out of 15 patients presented complications (an atrophic nonunion and a peri‑implant distal fracture). None of the patients had a nerve palsy prior neither after the surgery. No other complications, including infection, were registered during follow-up. Shoulder range of motion showed the following means: abduction of 147° (range 50°-180°), anterior flexion of 144° (range 80°-180°), external rotation of 77,5 ° (range 70°-80°) and internal rotation of 54.5° (range 45°-60°). All patients recovered their pre-fracture elbow range of motion. All patients presented less than 10° of angular deviation in varus/valgus or ante/recurvatum after the surgical procedure. At the end of the follow-up, all final functional scores were "good" or "excellent": mean Constant-Murley score was 72 ± 13 (range 38-91), ASES score was 73 ± 12 (range 41-88), UCLA shoulder scale was 30 ± 3,5 (range 10-35), and Q-DASH score was 16.5 ± 0,11 (range 4-57). CONCLUSION When applied correctly, the treatment of diaphyseal humeral fractures involving the proximal humerus using a polyaxial locking helical plate with a MIPO technique is a reliable treatment method. It has high union rates with low complications.

Abstract
BACKGROUND Injuries to the hamstring muscles and tendon complex are among the most frequent muscular injuries with proximal hamstring tendon avulsion being a particularly severe form. The surgical treatment of these injuries is superior to conservative management with respect to patient satisfaction, recovery of muscle strength and function as well as return to sport rates. It is therefore the method of choice. OBJECTIVE Presentation and comparison of the surgical results after treatment with titanium, polyether ether ketone (PEEK) and all suture anchors. MATERIAL AND METHODS A systematic search was carried out in the PubMed medical database and the results are summarized. RESULTS All systems exhibit comparable biomechanical properties regarding elongation and ultimate failure load. Tendon repair with these anchors results in good to excellent clinical outcomes and shows high return to sport and low complication rates. Patient satisfaction after hamstring tendon repair is reported to be over 90% and return to sport rate is 80-100%. The muscle strength recovers to 80-90% in comparison to the contralateral side. CONCLUSION All available anchors systems provide good to excellent clinical outcomes and an explicit advantage for one anchor system could so far not be shown.

Abstract
OBJECTIVE To explore clinical effectiveness and safety of ultrasound-guided closed reduction and K-wires internal fixation in treating of Kilfoyle Ⅱand Ⅲ medial condylar fracture of humerus in children. METHODS Clinical data of 32 children with medial condylar fracture of humerus treated with closed reduction and internal fixation with K-wires under the guidance of ultrasound were retrospectively analyzed from January 2014 to August 2019, including 23 males and 9 females, age ranged from 3.2 to 12.8 years old with an average of (8.3±2.1) years old;According to classification of Kilfoyle, 12 patients classified to typeⅡ and 20 patients were type Ⅲ;5 patients combined with elbow dislocation;the time from injury to operation ranged from 1 to 5 days with an average of (3.1±1.3) days. Radiological evaluation of treatment results and complications were observed. At the final follow up, Mayo elbow performance score(MEPS) was used to evaluate elbow function. And humerus-ulna angle on the affect side and healthy side were measured and compared. RESULTS All patients were followed up from 8 to 26 months with an average of(19.3±5.5) months. All fractures were healed well, the healing time ranged from 4 to 6 weeks with an average of (4.5±0.5) weeks. No infection, vascular and nerve injury, bone nonunion, trochlear necrosis, cubitus varus or valgus deformity were occurred. According to Mayo scoring, all patients were assessed as excellent. There was no significant difference in angle of humerus-ulna between affectedside (9.5±3.6)° and healthy side (9.1±3.5)°, and no difference in MEPS scores between affected side(95.3±2.5) and healthy side(96.3±2.2)(P>0.05). CONCLUSION For Kilfoyle typeⅡand Ⅲ medial condylar fracture of humerus in children, closed reduction and internal fixation with K-wire under ultrasound guidance is a safe and effective method, and could promote in further.

Abstract
BACKGROUND Postoperative management regimes vary following open reduction and internal fixation (ORIF) of unstable ankle fractures. There is an evolving understanding that extended periods of immobilisation and weight-bearing limitation may lead to poorer clinical outcomes. Traditional non-weight-bearing cast immobilisation may prevent loss of fixation, and this practice continues in many centres. The purpose of this trial is to investigate the safety and efficacy of immediate weight-bearing (IWB) and range of motion (ROM) exercise regimes following ORIF of unstable ankle fractures with a particular focus on functional outcomes and complication rates. METHODS A pragmatic randomised controlled multicentre trial, comparing IWB in a walking boot and ROM within 24 h versus non-weight-bearing (NWB) and immobilisation in a cast for 6 weeks, following ORIF of all types of unstable adult ankle fractures (lateral malleolar, bimalleolar, trimalleolar with or without syndesmotic injury) is proposed. All patients presenting to three trauma units will be included. The exclusion criteria will be skeletal immaturity and tibial plafond fractures. The three institutional review boards have granted ethical approval. The primary outcome measure will be the functional Olerud-Molander Ankle Score (OMAS). Secondary outcomes include wound infection (deep and superficial), displacement of osteosynthesis, the full arc of ankle motion (plantar flexion and dorsal flection), RAND-36 Item Short Form Survey (SF-36) scoring, time to return to work and postoperative hospital length of stay. The trial will be reported in accordance with the CONSORT statement for reporting a pragmatic trial, and this protocol will follow the SPIRIT guidance. DISCUSSION Traditional management of operatively treated ankle fractures includes an extended period of non-weight-bearing. There is emerging evidence that earlier weight-bearing may have equivocal outcomes and favourable patient satisfaction but higher wound-related complications. These studies often preclude more complicated fracture patterns or patient-related factors. To our knowledge, immediate weight-bearing (IWB) following ORIF of all types of unstable ankle fractures has not been investigated in a controlled prospective manner in recent decades. This pragmatic randomised-controlled multicentre trial will investigate immediate weight-bearing following ORIF of all ankle fracture patterns in the usual care condition. It is hoped that these results will contribute to the modern management of ankle fractures. TRIAL REGISTRATION ISRCTN Registry ISRCTN76410775 . Retrospectively registered on 30 June 2019.

Abstract
OBJECTIVE To explore clinical effect of locking plate external fixation combined with membrane induction technology in treating open and comminuted tibial fractures with bone defects. METHODS Totally 92 patients of open and comminuted tibial fractures with bone defects were chosen form January 2018 to July 2019, and randomly divided into external fixation group and internal fixation group, 46 patients in each group. In external fixation group, there were 29 males and 17 females, aged from 25 to 62 years old, with an average of (37.45±10.92) years old;according to AO classification, 15 patients were type A, 22 patients were type B and 9 patients were type C;according to Gustilo classification, 21 patients were typeⅡ, 10 patients were type ⅢA, 10 patients were type ⅢB, 5 patients were type Ⅲ C;treated by fracture reduction with locking plate external fixation. In internal fixation group, there were 31 males and 15 females, aged from 23 to 60 years old, with an average of(36.88±10.64) years old;according to AO classification, 18 patients were type A, 20 patients were type B and 8 patients were type C; according to Gustilo classification, 22 patients were typeⅡ, 11 patients were type ⅢA, 7 patients were type ⅢB, 6 patients were type Ⅲ C;treated by traditional open reduction with plate internal fixation. Operation time, intraoperative blood loss, incision length, hospital stay, fracture healing time and lower limb full weight-bearing time and postoperative complications between two groups were observed and compared, bone mineral density, osteocalcin, blood calcium and phosphorus before operation and 1 month after operation. RESULTS All patients were followed up from 12 to 18 months with an average of (14.92±2.46) months. Operation time, intraoperative blood loss, incision length, hospital stay, fracture healing time and lower limb full weight-bearing time of external fixation group were significantly better than that of internal fixation group(P<0.05). Postoperative bone mineral density, osteocalcin, blood calcium and phosphorus at 1 month in external group were higher than that of internal fixation group (P<0.05). Four patients in external fixation group occurred complications, 13 patients in internal fixtaion group, and occurrence rate of complications in external fixation group (8.70%) was lower than that of internal fixtaion group (28.26%)(χ2=4.618, P=0.032). CONCLUSION Locking plate external fixation combined with membrane induction technology in treating open and comminuted tibial fractures with severe post-traumatic bone defects has advantages of less trauma, reliable fixation, shorter fracture healing time, and could improve bone metabolic activity with less postoperative complications.

Abstract
BACKGROUND The posterior plating technique could be used as a clinical alternative to parallel plating for treating comminuted distal humerus fractures (DHFs) successfully with good clinical results. However, the biomechanical characteristics for posterior fixation are still unclear. The purpose of this study is to evaluate the biomechanical properties of the posterior fixation and to make comparisons between the parallel and the posterior fixation systems. MATERIALS AND METHODS We performed a cadaveric biomechanical testing with two posterior plating systems (a posterior two plating and a single posterior pre-contoured Y plating system) and one parallel two plating system to treat AO/OTA type-C2.3 DHFs. Among three groups, we compared construct stiffness, failure strength, and intercondylar width changes after 5000-cycle fatigue loading and failure loads and failure modes after destructive tests in both the axial compression and (sagittal) posterior bending directions. The correlations between construct failure loads and bone marrow density (BMD) were also compared. RESULTS In axial direction, there were no significant differences in the stiffness and failure load between the posterior and the parallel constructs. However, in sagittal direction, the two-plate groups (posterior two plating and parallel plating group) had significant higher stiffness and failure loads than the one-plate group (single posterior Y plating). There was no fixation failure after 5000-cyclic loading in both directions for all groups. Positive correlation was noted between BMD and failure loads on parallel fixation. CONCLUSIONS We found that when using two plates for treating comminuted DHFs, there were no significant differences in terms of most biomechanical measurements between posterior and parallel fixation. However, the single pre-contoured posterior Y plate construct was biomechanically weaker in the sagittal plane than the parallel and the posterior two-plate constructs, although there was no fixation failure after the fatigue test for all groups regardless of the fixation methods. LEVEL OF EVIDENCE Biomechanical study.

Abstract
Objective To compare the clinical efficacy of pararectus and ilioinguinal approach in the treatment of acetabular fractures. Methods A retrospective analysis of the clinical data of 60 patients with acetabular fractures treated by the pararectus approach or the ilioinguinal approach from January 2016 to January 2019 was performed to record all data by comparing the length of the surgical incision, the time to expose the fracture and the amount of blood loss during the operation. Patients were routinely followed up at 1, 6 and 12 months postoperatively. The function of the hip joint after the operation (Improved Merle d' Aubigne and Postel scores) and the complications postoperation were recorded. Results There was a significant difference (mean ± SD) in the length of surgical incision [(11.2 ± 1.5) cm vs.(23.8 ± 2.1) cm], and in surgical exposure time [(10.8 ± 1.7) min vs.(19.9 ± 1.9) min] (P < 0.05) between the two approaches; there was no significant difference (mean ± SD) in intraoperative blood loss [(591.8 ± 131.4) mL vs. (614.6 ± 132.7) mL] or in hip function scores at the last follow‐up between the two groups (P > 0.05). In the pararectus approach group, there was one patient (3.3%) with postoperative wound fat liquefaction, and the wound completely improved by secretion culture, enhanced dressing and effective antibiotics, one patient (3.3%) developed lateral femoral cutaneous nerve injury; One case (3.3%) of postoperative myositis ossificans occurred in the ilioinguinal approach group, and there were no obvious symptoms. Conclusions These data suggest that for patients with acetabular fractures, both the pararectus approach and the ilioinguinal approach can achieve satisfactory surgical results, but the former has relatively simple operation and small incision length, which is in line with the modern concept of the minimally invasive pelvis.

Abstract
Background To investigate the clinical efficacy of locking compression plate fixation for the treatment of femoral intertrochanteric fractures in patients with preexisting proximal femoral deformity. Methods A retrospective analysis was conducted on 37 patients with femoral intertrochanteric fractures combined with preexisting proximal femoral deformity between January 2013 and July 2019. The patients included 24 males and 13 females aged from 23 to 69 years old, with an average age of 47.5 years. The preexisting proximal femoral deformities resulted from poliomyelitis sequela, proximal femoral fibrous dysplasia, malunion and implant failure combined with coxa vara after intramedullary nailing fixation. There were 6 cases of 31-A2.1, 6 cases of 31-A2.2, 20 cases of 31-A3.1, and 5 cases of 31-A3.2, determined based on the AO classification of intertrochanteric fractures. All fractures were managed through open reduction and locking plate fixation. The hip disability and osteoarthritis outcome score (HOOS) was used to assess hip function before injury and at the last postoperative follow-up. The short form 36 (SF-36) Health Survey Questionnaire was used to assess quality of life. Results Thirty-seven patients were followed up for 12 to 27 months (average, 20.7 months). All patients achieved bone healing within 5.1 months on average (range, 3 to 6 months). Postoperative complications included deep vein thrombosis in three patients, bedsores in one and delayed union in one patient. No other complications, such as surgical site infection, fat embolism, nonunion and re-fracture, were presented. There was no significant difference in the HOOS scores and the SF-36 Health Questionnaire outcomes at pre-injury and at the last postoperative follow-up (p > 0.05). Conclusions It is difficult to perform intramedullary fixation of femoral intertrochanteric fractures in patients with preexisting proximal femoral deformity, while locking compression plate fixation is a simple and effective method of treatment.

Abstract
OBJECTIVE Restoring humeral shaft alignment using direct or indirect reduction techniques with subsequent intramedullary stabilisation with an antegrade or retrograde inserted humeral nail. Achieving osseous union and restoration of painfree upper arm function. INDICATIONS Antegrade: Humerus shaft fractures located in the proximal 2/3 of the humerus. Combined fractures of the ipsilateral proximal humerus and humerus shaft. Segmental fractures of the humerus shaft. Pathological fractures or osteolysis (palliative indication). Retrograde: Humerus shaft fractures located in the middle and distal part of the humerus diaphysis. CONTRAINDICATIONS Acute infection in the area of the surgical approach; polytrauma with acute life-threatening haemodynamic instability. SURGICAL TECHNIQUE In the antegrade technique: anterolateral acromial approach. Determination of the correct nail entry point on the humeral head. Incision of the rotator cuff with longitudinal split of the fibres. Closed or semi-open fracture reduction. Insertion of an intramedullary nail with an appropriate length and diameter. Interfragmentary compression when required. Proximal and distal static interlocking with at least 2 bolts on each side. In the retrograde technique, the nail is inserted after opening of the medullary cavity directly proximal to the olecranon fossa. POSTOPERATIVE MANAGEMENT Functional aftertreatment with passive and active-assisted exercises during the first 3 weeks. Subsequent active exercises avoiding forced rotation of the arm. Sports activities and severe stress are avoided for 3 months. Postoperative radiographs as well as after 2, 6 and 12 weeks. RESULTS Very good healing results with excellent clinical and radiological healing are achieved in more than 90% of cases after both antegrade and retrograde nailing. Intraoperative problems that have been reported in up to 40% of cases occurred mainly with former generation nails or were attributable to technical errors. Correspondingly, with the closed reduction technique postoperative infections are rare (< 3%). Undesirable distraction at the fracture site is successfully corrected by intraoperative interfragmentary compression. Success and complication rates after intramedullary nailing and plate fixation are not significantly different. Functional shoulder-related problems may occur after antegrade nailing, whereas elbow problems may occur after retrograde nailing.

Abstract
BACKGROUND Randomized controlled trials have demonstrated that surgical stabilization of rib fractures (SSRF) in selected trauma patients is associated with potential benefits. This study evaluates the real-world outcomes of SSRF since its implementation at Westmead Hospital, Australia. We hypothesize these outcomes to be similar to that reported by best-evidence in the literature. MATERIALS AND METHODS A retrospective analysis of data on all consecutive SSRF performed between January 2013 to December 2018 was completed. RESULTS Sixty-three patients (54 male; average age 55.9 ± 14.1 y) with median ISS 24 (IQR 17;30) underwent SSRF. Thirty-seven patients were admitted to Intensive Care Unit (ICU), with median ICU length of stay (LOS) 10.0 (5.0-17.0) d. Median hospital LOS was 15.5 (10.0-24.8) d. Fifty-five (87.3%) patients did not have any surgery-specific complications. The highest observed surgical morbidity was wound infection (n = 4, 4.7%). There was one mortality after rib fixation that was not related to surgery. SSRF within 3 d of hospital presentation in ventilated patients with flail chest was associated with significantly reduced median ICU LOS (3.0 [2.0;4.0] versus 10.0 [9.3;13.0] d; P = 0.03). Early (2013-2015) versus late (2015-2018) phase SSRF implementation demonstrated no significant difference in outcome variables. CONCLUSION Experience with SSRF demonstrates early outcomes similar to best-evidence in the existing literature. As a quality assurance tool, ongoing evaluation of real-world data is needed to ensure that outcomes remain consistent with benchmarks available from best-evidence.

Abstract
OBJECTIVE The objective of the present paper was to investigate the value of obturator oblique and pubic ramus inlet views in guiding anterior column acetabular screw insertion. METHODS We collected pelvic CT scans at the diagnostic imaging center of our hospital between 2017 and 2019. Virtual three-dimensional (3D) models of the pelvis were created based on the CT scans. Then the transparency was adjusted to 30%. Two identical copies of the 3D model data were made. 3D model replications were divided into a control group and an experimental group. In the control group, the screw was inserted into the anterior acetabular column using obturator-outlet and iliac-inlet views. In the experimental group, the screw was guided under obturator oblique and pubic ramus inlet views. Based on whether the screw penetrated the hip joint and/or exited the pubic ramus, models were divided into three grades. Grade I: the screw travels completely within the anterior column bone corridor; Grade II: the screw exits the superior pubic ramus, but the length of the screw outside the channel does not exceed 1/2 of the anterior column; Grade III: the screw exits the superior pubic ramus and the length of the screw outside the corridor exceeds 1/2 of the anterior column. We compared the screw placement quality of the two groups and analyzed differences between genders. In addition, the distance between the screws and the acetabulum was recorded and compared among the two groups. RESULTS A total of 110 hemipelves were selected, including those of 80 men and 30 women, with an average age of 46.76 ± 14.26 years. In the control group, the screw quality of 64 models (58.2%) was Grade I. In the experimental group, 94 models (85.5%) had Grade I screw placement quality. Grade II screw placement quality accounted for 18.2% of the control group and 7.3% of the experimental group. In the control and the experimental groups, there were 26 and 8 cases with Grade III screw placement quality, respectively. The quality of screw placement in the experimental group was significantly better than that in control group, and the difference between the two groups was statistically significant (P < 0.01). The distance between the screw and the acetabulum in the control group and experimental group was 0.92 ± 0.49 mm and 2.78 ± 1.15 mm, respectively. The difference between the two groups was statistically significant. CONCLUSION Anterior column acetabular screws can be inserted successfully and more accurately using the obturator oblique and pubic ramus inlet views.

Abstract
OBJECTIVES Open reduction and internal fixation of both columns is considered the treatment of choice for displaced anterior column with posterior hemitransverse (ACPHT) fractures in non-geriatric patients. Plate fixation of one column combined with lag screw fixation of the other column allows to decrease operative time and approach-related morbidity compared to conventional both column plating. The aim of this biomechanical study was to evaluate whether single column plate plus other column lag screw fixation confers similar stability to both column plate fixation. Physiological loads were simulated using both the single-leg stance (SLS) as well as the sit-to-stand (STS) loading protocols. METHODS A clinically relevant ACPHT fracture model was created using fourth-generation composite hemipelves. Fractures were stabilized with three different fixation constructs: (1) anterior column plate plus posterior column screw fixation (AP+PCS), posterior column plate plus anterior column screw fixation (PP+ACS) and anterior column plate plus posterior column plate fixation (AP+PP). Specimens were loaded from 50 to 750 N with a ramp of 100 N/s. Fracture gap motion (FGM) and relative interfragmentary rotation (RIFR) between the three main fracture fragments were assessed under loads of 750 N using an optical 3D measurement system. RESULTS STS loading generally resulted in higher mean FGM and RIFR than STS loading in the AP+PCS and AP+PP groups, while no significant differences were found in the PP+ACS group. Compared to conventional both column plate fixation (AP+PP), PP+ACS displayed significantly higher FGM and RIFR between the iliac wing and the posterior column during SLS loading. No significant differences in FGM and RIFR were identified between the AP+PCS and the AP+PP group. CONCLUSION Overall, single column plate plus other column lag screw fixation conferred similar stability to conventional both column plate fixation. From a clinical point of view, AP+PCS appears to be the most attractive alternative to conventional AP+PP for internal fixation of ACPHT fractures.

Abstract
This article explores different nontraditional methods that could be adopted in clinical settings as alternatives to the traditional fibular fixation. Less invasive methods, such as intramedullary nail and screw fixation, might be viable alternatives for managing ankle fractures. These methods might especially benefit patients with poor soft tissue envelopes, low immunity, and poor bone quality. There is minimal soft tissue coverage for most orthopedic implants around the ankle. Various authors have highlighted the importance of minimally invasive surgery as an effective modality for ensuring superior prognosis for ankle fracture surgery or those fractures involving both the distal tibia and fibula.

Abstract
OBJECTIVES This study was conducted to evaluate clinically and radiologically the patients for whom compressive and non-compressive intramedullary nails were applied and to analyse the compression effectiveness in adult femur distal diaphysis fractures. HYPOTHESIS The compressive locked nails shortened the union period in the distal diaphysis fractures, and it was found to be an effective method, as the pseudoarthrosis rate was lower. MATERIAL AND METHODS A retrospective study was conducted among 59 patients for whom the compressive and non-compressive IMNs were applied to treat femur distal diaphysis fractures. Thirty-one for whom the non-compressive IMN was applied were categorised as group I, and 28 for whom the compressive nail was applied were categorised as group II. Finite element analysis was performed using 1.5mm compression, and a mean stress value of 34.67Mpa. RESULTS The mean values of union period were calculated as 13.6±2.4 weeks (range: 11-20 months) and functional score was 79.2, respectively in group I, and they were evaluated as a good grade. In group II, the respective mean values of union period were 11.5±2.6 weeks (range: 10-17 months) and functional score was 86, and they were evaluated as excellent. CONCLUSION Radiological and functional scores were determined to be better with interlocking compressive nails and shortened the fracture union period in the follow-up in adult femur distal diaphysis fractures.

Abstract
Objective The objective of the present paper was to explore the clinical effect of one approach anterior decompression and fixation with posterior unilateral pedicle screw fixation for thoracolumbar osteoporosis vertebral compression fractures (OVCF). Methods This is a single‐center retrospective analysis. A total of six thoracolumbar OVCF patients (four women and two men) with an average age of 65.2 years (58–72 years) who were treated between June 2016 and May 2018 were enrolled in the present study. The lesion segments included: 1 case at T11, 1 case at T12, 3 cases at L1, and 1 case at L2. The six thoracolumbar OVCF patients were treated with one approach anterior decompression and fixation with posterior unilateral pedicle screw fixation. After general anesthesia, patients were placed in the right lateral decubitus position, an approximately 10–15‐cm oblique incision was made along corresponding ribs, and the conventional left retroperitoneal and/or the extrapleural approach was performed for anterior lateral exposure. First, anterior decompression and fixation were performed, and then through the unilateral paraspinal muscle approach, posterior pedicle screw fixation was performed under the same incision. The back pain visual analogue scale (VAS), the Oswestry disability index (ODI), and the MacNab criteria were used to evaluate the clinical outcome. The radiographic analysis included the regional kyphosis angle and the fusion rate. Neurological status, operation time, intraoperative bleeding, the time of ambulation, hospital stay, and surgical complications were also assessed. Results Surgery was successful in all six patients, who were followed up for 31.6 months (range, 23–46 months). The operation time was 125–163 min, with a median of 135 min. The preoperative blood loss was 580–1230 mL, with a median of 760 mL. The time of ambulation was 3–5 days, with a median of 4.2 days. The hospital stay was 8–15 days, with the median of 10.5 days. According to the Frankel classification of neurological deficits, of two patients with grade C preoperatively, one had improved to grade D and one had improved to grade E at final follow up; among four patients with grade D preoperatively, at the final follow up one remained the same and three had improved to grade E. The postoperative back pain VAS score decreased significantly, from 6.17 ± 0.75 preoperatively to 0.83 ± 0.41 postoperatively (P < 0.05). The mean ODI score was 73.7 ± 5.86 preoperatively and reduced to 21.85 ± 3.27 postoperatively (P < 0.05). According to the MacNab criteria, at the final follow up, two patients rated their satisfaction as excellent, three patients as good, and one patient as fair. The mean regional kyphosis angle was 22.17° ± 6.01°before surgery, which improved to 9.33° ± 3.88° at the final follow up (P < 0.05). At the final follow up, there were two patients who had achieved a grade 2 bony fusion (33.3%), three patients grade 3 (50.0%), and one patient grade 4 (16.7%). No incision infections, internal fixation failures or other complications were found during the perioperative and the follow‐up period. Conclusion One approach anterior decompression and fixation with posterior unilateral pedicle screw fixation provides a novel method for thoracolumbar OVCF disease, with a satisfactory clinical outcome.

Abstract
OBJECTIVE Anatomical restoration of the function and anatomy of the talocrural joint, anatomical reduction of fractures of the lateral and medial malleoli and to address ligamentous instability when achieving exercise stability. INDICATIONS Dislocated and intra-articular fractures of the lateral and medial malleoli. CONTRAINDICATIONS Infections, peripheral arterial occlusive disease, critical soft tissue conditions. SURGICAL TECHNIQUE Placement in a supine position, lateral and medial access, reduction of the fractures by manipulation of the fragments with Kirschner wires or use of reduction clamps, control of the joint reduction, definitive fixation with traction screws and plate osteosynthesis of the distal fibula, screw, tension-band or plate osteosynthesis of the medial malleolus, in cases of syndesmosis instability exact restoration of the talocrural joint by implantation of adjusting screws, alternatively dynamic fixation with a suture-button system. POSTOPERATIVE MANAGEMENT Movement exercises of the talocrural joint after postoperative day 1, mobilization with partial weight-bearing of the affected leg with 20kg postoperatively for 6-8 weeks, with implantation of adjusting screws removal after 8 weeks and staged increase of weight-bearing, if necessary postoperative insertion of an orthesis. RESULTS The anatomical reconstruction is decisive. Surgically treated bimalleolar fractures show good to excellent long-term results, the increasing number of affected malleoli correlates with a poorer outcome.
