Abstract
BACKGROUND This cohort study aimed to estimate incidence rates of femoral shaft fracture in patients who were treated with antiresorptive drugs. METHODS We used data from the National Database of Health Insurance Claims of Japan from April 2009 and October 2016. All patients with new use of an antiresorptive drug, prescription-free period of ≥3 months, and no prior femoral fractures were included. Femoral shaft fractures were identified using a validated definition based on International Classification of Diseases, 10th revision (ICD-10) codes. Incidence rate ratios were estimated using Poisson regression, with adjustment for sex, age, and the Charlson Comorbidity Index. RESULTS We identified 7,958,655 patients (women: 88.4%; age ≥75 years: 51.2%). Femoral shaft fractures were identified in 22,604 patients. Incidence rates per 100,000 person-years were 74.8 for women, 30.1 for men, 30.1 for patients aged ≤64 years, 47.7 for patients aged 65-74 years, and 99.0 for patients aged ≥75 years. Adjusted incidence rate ratios in patients taking versus not taking each type of antiresorptive drug were 1.00 (95% confidence interval [CI], 0.98-1.03) for bisphosphonates, 0.46 (95% CI, 0.44-0.48) for selective estrogen receptor modulators, 0.24 (95% CI, 0.18-0.32) for estrogens, 0.75 (95% CI, 0.71-0.79) for calcitonins, and 0.93 (95% CI, 0.84-1.03) for denosumab. The adjusted incidence rate ratio for alendronate was 1.18 (95% CI, 1.14-1.22). CONCLUSION The incidence rates of femoral shaft fracture varied across patients treated with different antiresorptive drugs. Further research on a specific antiresorptive drug can increase understanding of the risk of femoral shaft fracture.

Abstract
Femoral shaft fractures are increasingly common due to various traumatic injuries. Intramedullary nail (IMN) is considered the gold standard treatment for these fractures, but comorbidities often require thorough trauma life support and intensive care. The primary goal of treatment is rigid fixation, early mobilisation, and long-term functional recovery. This article reviews current concepts in the treatment of femoral shaft fractures, including the effects of early or delayed operation, differences between antegrade or retrograde intramedullary nailing, alternative methods to using a fracture table, methods to predict nail length before operation, assessing femoral rotation during an operation, and complications.

Abstract
BACKGROUND The operation object of robot-assisted fracture reduction surgery is the musculoskeletal tissue with rigid-compliance coupling characteristics. It is necessary to improve the interactive compliance and safety between the reduction robot and the musculoskeletal tissue. METHOD An adaptive variable impedance position/force tracking control strategy based on friction compensation is proposed. The stiffness of the reduction robot can be adaptively adjusted according to the contact force between the end-effector and the environment. The Stribeck friction force model of the branch chain electric cylinder is derived to improve the motion control performance. RESULTS The fracture reduction experiment is completed. The experimental results show that the adaptive variable impedance position/force control strategy can realize position and force tracking in fracture reduction. CONCLUSION A safety control strategy is proposed and applied to robot-assisted fracture reduction surgery, which improves the coordination and compliance of the human-robot interaction between the reduction robot and the patient.

Abstract
Gluteal compartment syndrome is a rare disorder and no definitive treatment has yet been established. Fasciotomy is often the treatment of choice for gluteal compartment syndrome, but there have been only a few cases that have improved with conservative therapy. A 26-year-old male with a body mass index of 40.5 who underwent femoral nail extraction surgery had severe pain in the right buttock and numbness in the right lower extremity. Initially, we suspected transient pain due to prolonged exposure to the same posture, but muscle weakness in the lower extremities and worsening of renal function appeared over time. Orthopedic evaluation revealed physical examination findings and MRI imaging findings consistent with gluteal compartment syndrome. Conservative treatment with temporary dialysis was chosen instead of fasciotomy because of the time required for diagnosis. Dialysis was started on postoperative day 3, renal function and muscle weakness recovered over time, and the patient was discharged home on postoperative day 37. At six months post-op, the patient was walking without pain and he had no changes in his peripheral neurologic examination compared to his preoperative baseline. Orthopedic surgeons should always be aware of the possibility of gluteal compartment syndrome when especially obese patients with prolonged operation times appeal to acute buttock pain. Diagnosis should be made as early as possible to get a good prognosis.

Abstract
Background and objective Intramedullary femoral nailing (IMN) is the gold standard for managing femoral shaft fractures (FSFs). Though good clinical outcomes and union rates have been reported following this procedure, it has also been commonly associated with perioperative complications. Positioning the patient in lateral decubitus, avoiding a fracture table, or using manual traction have been touted as possible techniques to reduce perioperative complications in IMN. However, given the scarce availability of comparative research, the decision to employ any of the techniques mentioned above is often guided by surgeon preference alone. In light of this, the purpose of this study was to determine whether the use of free-leg draping using either supine or direct lateral positioning with manual traction reduces perioperative complications among trauma patients undergoing an anterograde femoral nailing surgery when compared to using a fracture table. Methods Consecutive adult patients from a level-one trauma center undergoing unilateral antegrade femoral fixation surgeries between 2016 and 2020 were retrospectively evaluated for possible inclusion in the study. Relevant perioperative and postoperative data, including length of hospital or ICU stay and perioperative complications, were included in the analysis. This study received research ethics board approval before data collection began. Results A total of 91 patients were ultimately included in the final analysis: 61 patients were included in the free-leg draping with manual traction group (FL) and 30 patients were included in the traction table group (TT). Patients in the FL group had a similar operative and fluoroscopy time, blood loss, length of stay, and time on the ventilator. Subgroup analysis comparing positioning within the FL group revealed non-significant differences in fluoroscopy time (p=0.59) and length of stay (p=0.20) between the lateral and supine groups. Moreover, no differences in operative time, blood loss, and time on the ventilator were observed between lateral and supine groups. Conclusion Based on our findings, there were no significant differences in terms of operative or fluoroscopy time, perioperative complications, or length of time in the hospital or on the ventilator between the groups. Our study was limited by its small sample size and incomplete data. Further prospective randomized research is required to reach definitive conclusions on the appropriate manner to treat patients with these complex and morbid injuries.

Abstract
To investigate the effect of dexmedetomidine (DEX) on hemodynamics and recovery period after femoral shaft fracture surgery. Fifty-two patients, aged 3 to 7 years, who underwent femoral shaft fracture reduction surgery in our hospital in 2019 were randomly divided into the experimental group (n = 26) and the control group (n = 26). Both groups were given routine propofol combined with remifentanil by intravenous anesthesia. The experimental group was continuously pumped with DEX after induction of anesthesia, while the control group was continuously pumped with the same volume of normal saline. The mean arterial pressure (MAP) and heart rate (HR) were recorded before anesthesia induction (T0), when laryngeal mask was inserted (T1), when skin was cut (T2), when intramedullary needle was inserted (T3), and when laryngeal mask was removed (T4). Extubation time after anesthesia withdrawal was recorded in the 2 groups. According to the Pediatric Anesthesia Emergence Delirium score, the agitation and the incidence of agitation were recorded immediately after extubation (T5), 10 minutes after entering the recovery room (T6) and 30 minutes after entering the recovery room (T7). There was no significant difference in MAP and HR between the 2 groups at T0 and T1 time points (P > .05). The MAP and HR of the experimental group at T2 to T4 were significantly lower than those of the control group (P < .05). The extubation time of the experimental group was longer than that of the control group (P < .05), but the Pediatric Anesthesia Emergence Delirium score and the incidence of agitation in the recovery period of the experimental group were lower than those of the control group (P < .05). In femoral shaft fracture surgery, intravenous anesthesia combined with continuous pumping DEX can effectively stabilize the hemodynamics of patients, and the incidence of postoperative agitation during anesthesia recovery is low.

Abstract
Femoral shaft fracture occurs through the diaphyseal region of the femur. The intertrochanteric (IT) fracture is an extracapsular fracture that occurs through the proximal metaphyseal area of the femur. The ipsilateral femoral shaft and IT fractures happen in rare cases following high-energy trauma. These fractures are difficult to manage due to their complexity. They are usually managed surgically and require prompt physiotherapeutic management postoperatively. The postoperative complications involve pain, stiffness, reduced muscle strength, deep vein thrombosis, muscular weakness, and atrophy. These complications occur primarily due to immobilization. In our case, the 30-year-old male patient was a known case of schizophrenia for three years. He met with a road traffic accident (RTA) while driving a car and acquired ipsilateral femoral shaft and IT fractures. He presented with the chief complaints of pain, swelling, deformity over the right thigh, and unable to bear weight over the right lower limb. X-rays revealed a right-side ipsilateral IT fracture and a femoral shaft fracture. The patient underwent an operation that involved open reduction and internal fixation with a proximal femoral nail under spinal epidural anesthesia. We started physical therapy management on postoperative day three. On clinical evaluation, there was a decrease in the range of motion and muscle strength of the right lower limb. This case posed us with a challenge to deliver postoperative physiotherapeutic intervention without elicitation of the symptoms associated with schizophrenia. The physiotherapy protocol involved virtual reality-based (VR-based) interventions in adjunct to conventional therapeutic interventions like strengthening exercises, range of motion exercises, application of electrical modality, balance training, gait training, VR-based relaxation, and aerobic exercises. We used the Lower Extremity Functional Scale, Manual Muscle Testing, Range of Motion, Brief Psychiatric Rating Scale, and the Numerical Pain Rating Scale as outcome measures. The comparison of pre-and post-outcome measure scores demonstrates a significant improvement.

Abstract
Background: Femoral shaft fractures (FSFs) are a frequent injury in traumatology for which intramedullary nailing (IMN) is considered the gold standard treatment. Nonunion (NU) is one of the most frequent complications in FSF treated with IMN, with a percentage from 1.1% to 14%. Plate augmentation (PA), the addition of a compression plate and screws, with or without bone graft has been described as an effective option for the treatment of NU, improving the biomechanical conditions at the fracture site. The aim of this review was to analyze the literature relating to the use of PA in NU after IMN in FSFs to assess the efficacy of the technique. Methods: An electronic search on PubMed, Google Scholar, and Web of Science was conducted to search for all studies concerning PA of femoral shaft NUs after IMN. Results: Twenty-four studies were included in the review comprising a total of 502 patients with a mean age of 39.5 years. Of these, 200 hundred patients had atrophic pseudoarthrosis and 123 had hypertrophic pseudoarthrosis, while in 179, the type of pseudoarthrosis was not reported. The most frequently used plate for PA was the dynamic compression plate (DCP); in 87.1% of the cases, the authors added a bone graft to the plate fixation. In 98.0% of the patients, a complete bone union was achieved in a mean time of 5.8 ± 2.12 months. Conclusion: The patients treated with PA included in this review showed a good rate of consolidation in the femoral shaft NUs, with good functional recovery and a low incidence of complications.

Abstract
Objective To compare the biomechanical behaviors of the spatial bridge locking fixator (SBLF), single locking plate (SP), and double locking plate (DP) for AO/OTA 32‐A3.2 fractures using finite element analysis and biomechanical tests. Methods Axial loading of 700 N was conducted on the AO/OTA 32‐A3.2 model via finite element analysis. The von Mises stress and the interfragmentary movement (IFM) were comparatively analyzed in the three configurations above. On the mechanical tester, axial and torsional loading of 30 synthetic femurs (five specimens of each configuration for each test at random) was performed, and the interfragmentary movement, torsion angle, stiffness, and ultimate load were recorded and analyzed. Results The finite element analysis (FEA) results showed that the von Mises stress of the spatial bridge locking fixator (SBLF) was lower than that of the single locking plate (SP) and higher than that of the double locking plate (DP). At 700 N, the axial IFMs were 0.15–0.38 mm (SBLF), 0.03–0.84 mm (SP), and 0.02–0.07 mm (DP). The biomechanical experiment indicated that the axial interfragmentary movements (IFMs) were 0.44 ± 0.23 mm (SBLF), 1.02 ± 0.40 mm (SP), and 0.07 ± 0.07 mm (DP) (p < 0.001). The axial IFM of the SBLF group had the highest probability (79.26%) of falling within the ideal range (0.2–0.8 mm), and the SP and DP groups had probabilities of 27.10% and 3.14%, respectively. The axial stiffness in the SBLF group (1586 ± 130 N/mm) was significantly lower than that in the DP group (10,264 ± 2671 N/mm) (p < 0.001) but greater than that in the SP group (725 ± 178 N/mm) (p = 0.396). The range of axial loads to ultimate failure was 3385–4527 N (SBLF), 3377–4664 N (SP), and 3780–4804 N (DP). The shear motion of the fracture end was 0.35 ± 0.14 mm (SBLF), 0.16 ± 0.10 mm (SP), and 0.08 ± 0.04 mm (DP) (p < 0.001). The torsional stiffness was 1.68 ± 0.14 Nm/degree (SBLF), 2.32 ± 0.29 Nm/degree (SP) (SBLF&SP, p < 0.001), and 3.53 ± 0.73 Nm/degree (DP) (SBLF&DP, p < 0.001). Conclusions The SBLF structure may exhibit a better biomechanical performance compared with the SP and DP in providing the best quantity and more symmetrical interfragmentary movement for AO/OTA 32‐A3.2 fractures.

Abstract
Objective Our study compared the results of wedge‐shaped femoral shaft fracture following intramedullary (IM) nailing with or without fixation of the third fragment. Methods We retrospectively reviewed patients presenting with femoral shaft fracture with AO/OTA type 32‐B from 2011 to 2016. Patients were divided into two groups: closed reduction without touching the third fragment and open reduction with fixation of the third fragment. The fragment ratio, fragment length, nail size, dynamization or not, mRUST scores, union rate, and union time were compared between the two groups. Risk factors of non‐union were also investigated, including sex, age, fracture pattern, fracture location, dynamization, nail size, fragment ratio, fragment size, and postoperative fragment displacement. Results A total of 80 patients met inclusion criteria, 20 patients with wedge‐shaped shaft femoral fracture were managed with IM nailing and open reduction with fixation of the third fragment. Sixty patients were treated with IM nail without touching the third fragment. The union rate for the fixation and non‐fixation groups were 60.0% and 81.7%, respectively. The mean union time for the fixation group was 19 months vs 14 months for the non‐fixation group. Multi‐regression analysis showed larger nail size (odds ratio: 2.26) and fixation of the third fragment (odds ratio: 0.18) influenced fracture healing. Conclusions Fixation of the third fragment in wedge‐shaped shaft femoral fracture results in a longer union time and lower union rate. In the management of femoral fracture with a third fragment, a larger nail size is recommended and fixation should be performed in a closed manner. Fixation of the fragment may achieve better fracture reduction. However, disruption of the vasculature and surrounding structures may further result in nonunion of the fracture site.

Abstract
BACKGROUND A novel-design femoral nail (FN) with distal talon deployment (Talon-FN) has emerged in the market to cope with problematic distal locking. We aimed to compare the radiological and functional outcomes of the Talon-FN with a conventional FN (Con-FN) for the treatment of femoral shaft fracture (FSFs). METHODS This retrospective study included 85 patients (57 men, 28 women; mean age: 46.8±23.9 years) with FSFs (AO types 32-A and B) who were treated with FNs (Talon-FN: 41, Con-FN: 44) during October 2014-2018. Knee injury and Osteoarthritis Outcome Score Physical Function Shortform, Hip injury and Osteoarthritis Outcome Score Physical Function Shortform, Short musculoskeletal function assessment bother and dysfunction indexes were used for functional assessment. RESULTS The mean follow-up time was 25.8±6.7 months. The complication rates were 19.6% and 20.5% for Talon-FN and Con-FN, respectively (p=0.92). Malunion was the most common complication for each FN type (Talon-FN: 9.8%, Con-FN: 9.1%). All of the Talon-FN group's malunions were axial (shortening and malrotation) and happened gradually. In contrast, the Con-FN group's malu-nions were angular (varus and valgus) and caused by initial malreduction. The Talon-FN group's two patients with shortening (4.9%) had AO 32-B type fractures, and the other two with malrotation (4.9%) had AO 32-A3 type fractures, all of four fractures were localized distal to the femoral isthmus. The post-operative functional outcomes were similar between the groups (all p>0.05). The mean op-eration/fluoroscopy time and the mean blood loss were lower in the Talon-FN group, while the mean union time was shorter in the Con-FN group (all p<0.01). No nonunion was noted in either group. The reoperation rates were similar at approximately 5% (p=0.95). CONCLUSION Our study results revealed that the Talon-FN shortens the operation/fluoroscopy time and decreases the intra-operative blood loss with similar functional outcomes. However, the Con-FN seems to offer a more stable construct against axial malunion with a shorter bone union time. The Talon-FN should not be used in FSFs distal to the femoral isthmus with certain types of fractures prone to shortening and malrotation.

Abstract
INTRODUCTION Proximal peri-implant femoral fractures occur following intramedullary nailing (IMN) fixation for trochanteric, femoral shaft, and distal femoral fractures. However, analyses of secondary hip fractures (SHFs) using large clinical samples are lacking. Therefore, we aimed to report the incidence and clinical outcomes of SHF after nailing fixation (IMN or cephalomedullary nailing [CMN]) for overall femoral fractures. In addition, we focused on IMN for femoral shaft fractures and investigated the risk factors for SHF. METHODS This multicenter, retrospective, cohort study included 2,293 patients aged > 60 years who underwent nailing fixation for femoral fractures. The primary outcome was the incidence of SHF. In the assessment of clinical outcomes, we evaluated reoperation and the regaining of walking ability following SHF management. In addition, we conducted multivariable logistic regression analyses to examine the association between risk factors and SHF. RESULTS Seventeen (0.7%) patients had SHFs, including 12 femoral neck fractures and 5 trochanteric fractures. Antegrade IMN was the most common type of nailing fixation. Multivariable analysis demonstrated that the absence of femoral head fixation was significantly associated with the incidence of SHF following IMN for femoral shaft fractures (odds ratio, 17.0; 95% confidence interval, 1.9-2265.7; p=0.006). In the assessment of clinical outcomes, there were two reoperations (16.7%) in the secondary femoral neck fracture group. Patients with secondary trochanteric fractures tended to have a lower probability of regaining walking ability than those with secondary femoral neck fractures (20% vs. 50%). CONCLUSIONS In this multicenter study, the incidence of SHF after nail fixation for femoral fractures was 0.7%. The absence of femoral head fixation was significantly associated with SHF, and the clinical outcomes were poor. Therefore, femoral head fixation at the initial IMN fixation for femoral fractures may be a fixation option for surgeons to consider as an SHF prevention measure.

Abstract
Despite the advantages of anterolateral thigh (ALT) flaps, many surgeons are hesitant to choose a thigh with ipsilateral femoral fracture and internal fixation as the flap donor site. To cover the right mid-upper leg wound, a free ALT flap was harvested from the left thigh of a 55-year-old man who initially underwent closed retrograde intramedullary fixation for a left distal third femoral shaft fracture. The flap was based on a musculocutaneous perforator located in the mid-thigh, which was approximately 10 cm above the proximal fracture level. No adhesion or scar formation between the fascia and adipose tissue was noted when the flap was raised suprafascially, and the adipose tissue surrounding the trunk of the descending branch of the lateral circumflex femoral artery was found to have mild edema. The patient regained good aesthetic outcomes and a complete range of active motion in both lower extremities. Based on current evidence of the vascular anatomy of the ALT flap in the literature and our experience, an ipsilateral thigh with distal third femoral shaft fracture and closed retrograde intramedullary fixation should not be considered an absolute contraindication to ALT flap harvesting.

Abstract
BACKGROUND Closed intra-medullary nailing fixation is a method for treating fractured femurs with minimal invasiveness. However, this method lacks safety and precision. To avert prevailing problems such as extended cracks in the already broken bone, the design of a vibration damping robot and force evaluation system is essential. METHODS This paper presents a sensor-based clamping robot system embedded with a regulated pressurised air balloon. Drilling forces were monitored by a force sensor attached to the end robot effector, while the reduced vibration result was measured by a non-contact laser displacement sensor. A 2 degree-of-freedom (2DOF) model was developed. RESULTS Force and vibration data were obtained using a data acquisition module (EMS 309) and analysed using MATLAB software (Version R2015b). The results obtained show that both the frequencies and amplitudes of the vibration is reduced at 6 bar with effector's spindle speed of 1500 rpm. CONCLUSIONS This proposed concept shows that drilling force and vibration can be reduced simultaneously using a robot effector coupled with a damper.

Abstract
A bent intramedullary (IM) nail becomes challenging and technically demanding to the orthopaedic surgeon for nail extraction. A broken nail can be easily removed through the fracture site. However, a bent nail has to be broken before it can be removed. Several studies and case reports outline the strategies and techniques for removing a bent IM nail. However, there is a paucity of guidelines and standard protocol describing the best and inexpensive strategy. We report a case where two years following surgery for intramedullary nailing of the right femur, the IM mail was bent following secondary trauma. We used a technique based on the principles of an ability to fully cut the nail and extract it in two pieces by using a Jumbo cutter which is available in the orthopaedic armamentarium. This technique is simple yet economical, with the likelihood of causing less soft tissue damage and thermal necrosis.

Abstract
BACKGROUND Elastic stable intramedullary nailing has become the treatment of choice for femur shaft fractures in school-age children in developed world. However, in the sub-Saharan Africa, this management is still challenging because of the lack of fluoroscopy in more hospitals. We performed either primary open reduction and intramedullary K-wire fixation (PORIKF) or conservative treatment. The aim of this study was to compare the clinical and functional outcomes of these two procedures employed. PATIENTS AND METHODS This retrospective study included 62 children with 64 fractures (10 years on an average; range: 6-15 years) treating for femoral shaft fractures either by PORIKF (n = 21; 23 fractures) or skin traction followed by spica cast (n = 41) between 2008 and 2017. Outcomes were assessed using Flynn criteria. Comparisons were made by Fisher and Student's t-test with a significant P < 5%. RESULTS Outcomes were satisfactory in 21 cases (91%) in the PORIKF group compared with 32 (78%) in the conservative group (P = 0.3012). The average hospital stay was 18.6 days in the PORIKF group, whereas it was 20 in the conservative group (P = 0.0601). The mean time for bone union was 13.9 weeks in the PORIKF group and 13.2 weeks in the conservative group, (P = 0.4346). There was a statistically significant difference between the two groups in terms of major complications (P = 0.0177). One patient had osteomyelitis in the PORIKF group. Unacceptable shortening >2 cm was observed only in the conservative group. The average time to return to daily activities was 30 days shorter in the PORIKF group when compared to conservative group (P < 0.05). CONCLUSION PORIKF provides better results than conservative treatment. Open reduction did not increase the rate of infectious complication.

Abstract
RATIONALE Pediatric femoral shaft combined with ipsilateral femoral neck fractures are very rare but challenging injuries fraught with the development of avascular necrosis, coxa vara, and leg length discrepancy. Majority of the previous reports indicated the neck femur fracture was fixed with cannulated screws or/and pins, femoral shaft fracture was stabilized with a plate and screws. However, we used cannulated screws combined with elastic stable intramedullary nails to minimally invasive procedures treat this type of injury and achieved good follow-up results. PATIENT CONCERNS A 7-year-old boy (Case 1) was hospitalized due to a traffic accident resulting in swelling and deformity of the right thigh accompanied by limited mobility of hip and knee. A 5-year-old male child (Case 2) presented with pain and swelling in the bilateral lower limb after fall from approximately 12 feet. DIAGNOSES Physical examination, X-ray film, and computed tomography were performed. Both patients were diagnosed with ipsilateral femoral neck and shaft fracture. INTERVENTIONS The fractures were reduced closed by image-intensifier imaging. Two partially threaded cancellous screws were used to fix femoral neck fracture, and elastic intramedullary nails were performed to stable the femoral shaft fracture. Postoperatively, the patients were immobilized in a one-and-a-half hip spica cast for six weeks. The internal fixations were removed after one year. OUTCOMES Case one was follow-up at 14 months and the other one was followed up for 3 years. And at the last follow-up showed a normal and painless hip function. No clinical complications were found during follow-up visit, including head penetration, implant failure, fracture nonunion, avascular necrosis and hip varus deformity. LESSONS Clinician should carefully check and read relevant imaging data to avoid missed diagnosis. And the internal fixation method described in this paper may be more minimally invasive.

Abstract
BACKGROUND Locking plate (LP) is a good choice in the treatment of length-unstable femoral shaft fracture in children. Monolateral external fixator (EF) has been reported for this condition for decades. This study aims to compare the clinical outcomes of school-aged children with length-unstable femoral shaft fracture treated with LP vs. EF. METHODS Patients aged 5-11 years old with length-unstable femoral shaft fractures treated at our institute from January 2014 to January 2018 were retrospectively reviewed and categorized into LP and EF groups. The preoperative data, including baseline information of the patients, radiographic parameters, and types of surgical procedure, were collected from the hospital database, and postoperative data, including complications, were collected during the follow-up visits. RESULTS Overall, 36 patients (average, 8.2 ± 2.1 years; male, 20; female, 16) in the LP group and 35 patients (average, 8.3 ± 2.3 years; male 20, female 15) in the EF group were included. There was significantly less operative time for EF (45.4 ± 7.8 min) compared with LP (67.8 ± 11.3 min) (P < 0.001). As for the frequency of fluoroscopy, there was a significant difference between the EF (13.9 ± 2.4) and LP (16.5 ± 3.2) groups (p < 0.001). The rate of major complications was not significantly different between these two groups. There was a significant difference between the EF group (11.2 ± 5.8 mm) and the LP group (7.5 ± 1.6 mm) group concerning limb length discrepancy (P < 0.001). CONCLUSION Both LP and EF produce satisfactory outcomes in school-aged children with length unstable femoral shaft fractures. External fixation remains a viable choice without the necessity of secondary surgery for hardware removal.

Abstract
Femoral shaft fracture is one of the most common types of fracture encountered in the clinic. For certain complex femoral shaft fractures, the traditional intramedullary nail may not provide sufficient stability. Therefore, novel intramedullary nail systems are required. The femur 3D model and the internal fixation model were designed using Mimics 17.0 (Materialise), Geomagic Studio 2012 (Raindrop) and Solidwork 2016 (Dassault) software. The validity of the models was verified through comparison with previous data in silico. To further simulate the comminuted femoral shaft fracture, the novel and traditional type of intramedullary nail system were included in the finite element analysis with the software. The displacement and stress distribution of the two internal fixations were compared using Abaqus 6.14 (Dassault) software. The effectiveness of the model was verified. The stress at the fixed end of the novel intramedullary nail system was greater than that at the fixed end of the traditional intramedullary nail system. However, the displacement of the novel intramedullary nail method was smaller than that of the traditional intramedullary nail. The novel intramedullary nail system features good stability and stress stimulation at the broken end, which is beneficial for bone healing. The present study may provide a theoretical basis for the selection of a means of internal fixation in the clinic.

Abstract
OBJECTIVE In this study, a new type of reduction device for femoral shaft fractures was developed and designed. The reduction procedure was also standardized and is expected to be useful in clinical practice. METHODS A bone traction retractor that consisted of a special traction needle, a resistant sleeve, a crossbar and an arc-adjusting bar was designed. Forty-eight patients (32 males and 16 females, mean age 33.21±7.03 years old) with femoral shaft fractures treated in our hospital from January 2016 to December 2017 were selected. According to the AO classification, there were 15 patients with type A, 24 patients with type B and 9 patients with type C fractures. All patients were treated with transverse bone traction for closed reduction of femoral shaft fractures and femoral reconstruction with intramedullary nails for final fixation. The injured side, preoperative delay time, reduction and operative times, operative blood loss, drilling frequency, number of open reduction cases, hospitalization days, fracture healing time, postoperative HSS function score and complications were recorded. RESULTS All 48 patients were treated with transverse bone traction using our novel device to obtain reduction. The average time needed for reduction was 19.98±4.66 min. The operating time was 60-100 min, with an average of 78.65±16.81 min, and the average intraoperative blood loss was 131.91±30.22 ml. Open reduction was performed in 8 patients: 1 patient in the experimental group and 7 patients in the control group. The average hospitalization days was 7.78±2.81 days, the fracture healing time was 10 to 15 weeks, with an average of 12.44±2.63 weeks, and the postoperative HSS score was 80-95 points, with an average of 86.52±6.03 points. None of the patients had coxa vara, nonunion, internal fixation failure, infection, nerve injury, limb length discrepancy or other complications. CONCLUSION In this study, the transverse bone traction reduction technique and the design of a proprietary reduction device system were proposed, with high clinical application. The transverse bone traction reduction technique has the advantages of simple operation, reliable reduction and limited intraoperative fluoroscopy in the minimally invasive treatment of femoral shaft fractures.

Abstract
OBJECTIVE To explore the effectiveness of Ilizarov external fixation without bone graft in the treatment of atrophic femoral shaft nonunion. METHODS The clinical data of 12 patients with atrophic femoral shaft nonunion admitted between October 2010 and January 2017 were retrospectively analyzed. There were 8 males and 4 females, aged from 24 to 61 years, with an average age of 41.7 years. The nonunion sites located in the middle and upper femur in 7 cases and in the distal femur or supracondylar in 5 cases. The disease duration ranged from 1 to 9 years, with an average of 3.7 years. Previous operations ranged from 1 to 9 times, with an average of 2.8 times. The original fixator was removed, the fracture end of nonunion was debrided, and Ilizarov external fixator was installed. In patients with the length of bone defect less than 4 cm, direct compression fixation was performed during operation; in patients with limb shortening more than 2.5 cm, proximal femoral osteotomy and bone lengthening components were required to prepare limb lengthening after operation; all patients did not receive bone graft. The wearing time of external fixator, clinical bone healing time of nonunion fracture end, and complications were recorded. The effectiveness was evaluated by Paley's nonunion evaluation criteria. RESULTS All patients were followed up 24-50 months, with an average of 30 months. Bony union was achieved in all 12 cases with a healing time of 6.0-23.5 months (mean, 11.5 months). The wearing time of external fixator ranged from 7 to 25 months, with an average of 13.5 months. At last follow-up, according to Paley's nonunion evaluation criteria, the results were excellent in 6 cases, good in 4 cases, and fair in 2 cases, with an excellent and good rate of 83.3%. Sagittal angulation deformity of femur more than 7° occurred in 4 cases, with no significant effect on knee extension function, and no special treatment such as osteotomy was performed. Two patients had shorter limbs (>2.5 cm) after operation and were replaced by high shoes; 4 patients with trans-knee fixation lost knee joint mobility of 10-30° after operation; 10 cases of needle tract infection occurred, of which 4 cases with infection and loosening of fixed needle were replaced and re-fixed after needle extraction, the remaining 6 cases of infection without loosening of fixed needle were controlled by local dressing change, needle nursing, and oral cephalosporin anti-inflammatory drugs. No complications such as deep infection and vascular nerve injury occurred. CONCLUSION Ilizarov external fixation has a high healing rate for atrophic femoral shaft nonunion, which is relatively minimally invasive and can avoid bone grafting. Its preliminary effectiveness is exact, and it is also effective for patients who have experienced multiple failed operations. It is necessary to pay attention to the nursing and rehabilitation training after external fixation.

Abstract
Background This study retrospectively evaluated the clinical outcomes of intramedullary nailing of femoral shaft fractures with third fragments and analyzed the risk factors for delayed union. Methods Retrospective analyses involving 51 patients who underwent intramedullary nailing of femoral shaft fractures with third fragments (AO classification type B, 35 cases; type C, 16 cases) were conducted. Delayed union was defined as either more than 10 months required for callus formation in more than three of the four cortical bone surfaces observed in the frontal and lateral radiographic views or the requirement for additional surgery such as nail conversion or bone transplantation. Seventeen patients developed delayed union (D group). Thirty-four patients achieved bony union within 9 months (U group). The following background variables were compared between groups: age at the time of the injury; AO classification; ratio of open fracture; waiting period before surgery; rate of the infraisthmal fracture; diameter of the intramedullary nail; ratio of the intramedullary nail to the femur; length and displacement of the third fragment; and use of open reduction, poller screws, or dynamization. Results Significant differences were found between the D and U groups for age (32.2±14.1 vs. 25.3±9.6 years), open fracture ratio (35.3% vs. 11.8%), and displacement of the third fragment (13.7±6.4 vs. 9±6.3 mm). Multiple logistic regression analysis only identified displacement of the third fragment as a risk factor for delayed union (p=0.03; OR 1.13; 95% CI 1.01 to 1.26). Discussion Delayed union was observed in 17 cases (33.3%) after intramedullary nailing of femoral shaft fractures with third fragments. Displacement of the third fragment influenced delayed union. Level of evidence Level III.

Abstract
BACKGROUND/OBJECTIVES Limited studies suggest lower-extremity (LE) fractures are morbid events for nursing home (NH) residents. Our objective was to conduct a nationwide study comparing the incidence and resident characteristics associated with hip (proximal femur) vs nonhip LE (femoral shaft and tibia-fibula) fractures in the NH. DESIGN Retrospective cohort study. SETTING US NHs. PARTICIPANTS We included all long-stay residents, aged 65 years or older, enrolled in Medicare from January 1, 2008, to December 31, 2009 (N = 1 257 279). Residents were followed from long-stay qualification until the first event of LE fracture, death, or end of follow-up (2 years). MEASUREMENTS Fractures were classified using Medicare diagnostic and procedural codes. Function, cognition, and medical status were obtained from the Minimum Data Set prior to long-stay qualification. Incidence rates (IRs) were calculated as the total number of fractures divided by person-years. RESULTS During 42 800 person-years of follow-up, 52 177 residents had an LE fracture (43 695 hip, 6001 femoral shaft, 2481 tibia-fibula). The unadjusted IRs of LE fractures were 1.32/1000 person-years (95% confidence interval [CI] = 1.27-1.38) for tibia-fibula, 3.20/1000 person-years (95% CI = 3.12-3.29) for femoral shaft, and 23.32/1000 person-years (95% CI = 23.11-23.54) for hip. As compared with hip fracture residents, non-hip LE fracture residents were more likely to be immobile (58.1% vs 18.4%), to be dependent in all activities of daily living (31.6% vs 10.8%), to be transferred mechanically (20.5% vs 4.4%), to be overweight (mean body mass index = 26.6 vs 24.0 kg/m2 ), and to have diabetes (34.8% vs 25.7%). CONCLUSIONS Our findings that non-hip LE fractures often occur in severely functionally impaired residents suggest these fractures may have a different mechanism of injury than hip fractures. The resident differences in our study highlight the need for distinct prevention strategies for hip and non-hip LE fractures.

Abstract
Well leg compartment syndrome (WLCS) is a rare complication which can occur following urological, gynecological, general surgical or orthopedic surgeries carried out with the lower limb in the hemilithotomy position. WLCS is associated with significant morbidity and mortality because delay in diagnosis and treatment can lead to loss of function and even life-threatening complications. During orthopedic surgeries on a traction table, such as femoral nailing, the contralateral “well leg” is often placed in the hemilithotomy position, thus facilitating the use of fluoroscopy. This position (also named the Lloyd-Davis position) consists of hip flexion, abduction, external rotation and knee flexion. We present the cases of two teenaged patients who underwent femoral nailing on an extension table of a femoral fracture and developed WLCS. We also present a review of the literature and a discussion of the pathophysiology, risk factors and treatment of this condition. Clinicians need to be aware of the risk factors for WLCS and have high index of suspicion. Further studies looking at the risks, benefits and feasibility of ways to reduce this risk are required.

Abstract
PURPOSE Intramedullary nailing (IMN) is a popular method in the management of femoral shaft fractures (FSFs). However, whether the association of IMN with pulmonary fat emboli can compromise the pulmonary and nervous systems is debatable. The purpose of this study is to compare IMN with the locked dual plating (LDP) method by assessing the clinical outcomes of FSF patients with head or chest injury. METHOD A total of 126 FSF patients were included in this study between January 2010 and July 2016 and divided into LDP and IMN groups. Patient demographic characteristics, operative time, blood loss, Harris Hip Score, Lysholm Knee Score, radiological outcomes, and systemic complications were collected and compared between the two treatment groups. Patients were followed up for at least 12 months. RESULTS The LDP group performed better than IMN in terms of operative time, estimated blood loss amount, and malunion rate. Differences in function scores, fracture union rate, overall pulmonary complication rate, and in-hospital mortality between the two groups were not significant. Average radiographic union time was significantly longer in the LDP group (36.3 weeks) than in the IMN group (32.5 weeks). One case of fixation failure occurred postoperatively in the LDP group, whereas one case of fracture nonunion took place in the IMN group. CONCLUSION Our findings suggest that dual-plating fixation is a promising method for FSFs with multiple injuries. However, the retrospective nature of this study necessitates high-quality trials to be performed to assess the clinical efficiency of dual plating.

Abstract
To evaluate the biomechanical stability of femoral shaft fracture fixation using different locking plates combined with different screw layout, for two different fracture settings, we build six groups different length locking plate combined with different screw number and different screw layout, fix with the fracture models respectively, and use the biomechanical finite element method to analysis the models. Then we attain the axial displacement and equivalent stress distribution of the internal fixation system under the action of axial load. The research shows that filling relatively softer material in femoral fracture can guarantee the stability of the internal fixation system, the long plate combined with less screw layout is obviously better than the short plate combined with the all screw layout, the same length plate combined with the selective screw layout is more effective than combined with the all screw layout. And plate combined with screws fixed in four threaded hole of distal fracture make the screw system stress disperse, and avoiding screw fixed in proximal fracture can alleviate the stress concentration of screws.

Abstract
AIMS While use of large national clinical databases for orthopaedic trauma research has increased dramatically, there has been little study of the differences in populations contained therein. In this study we aimed to compare populations of patients with femoral shaft fractures across three commonly used national databases, specifically with regard to age and comorbidities. PATIENTS AND METHODS Patients were identified in the Nationwide Inpatient Sample (NIS), National Surgical Quality Improvement Program (NSQIP) and National Trauma Data Bank (NTDB). RESULTS The distributions of age and Charleston comorbidity index (CCI) reflected a predominantly older population with more comorbidities in NSQIP (mean age 71.5; sd 15.6), mean CCI 4.9; sd 1.9) than in the NTDB (mean age 45.2; sd 21.4), mean CCI = 2.1; sd 2.0). Bimodal distributions in the NIS population showed a more mixed population (mean age 56.9; sd 24.9), mean CCI 3.2; sd 2.3). Differences in age and CCI were all statistically significant (p < 0.001). CONCLUSION While these databases have been commonly used for orthopaedic trauma research, differences in the populations they represent are not always readily apparent. Care must be taken to understand fully these differences before performing or evaluating database research, as the outcomes they detail can only be analysed in context. TAKE HOME MESSAGE Researchers and those evaluating research should be aware that orthopaedic trauma populations contained in commonly studied national databases may differ substantially based on sampling methods and inclusion criteria.

Abstract
BACKGROUND AND OBJECTIVE Intramedullary nailing is commonly used for treating femoral shaft fractures, one of the most common long bone fractures in adults. The reamed intramedullary nail is considered the standard implant for femoral fractures. This meta-analysis was performed to verify the superiority of reamed intramedullary nailing over unreamed intramedullary nailing in fractures of the femoral shaft in adults. Subgroup analysis of implant failure and secondary procedure was also performed. METHODS Electronic literature databases were used to identify relevant publications and included MEDLINE (Ovid interface), EMBASE (Ovid interface), and the Cochrane Central Register of Controlled Trials (CENTRAL; Wiley Online Library). The versions available on January 30, 2016, were utilized. Only human studies, which were designed as randomized controlled clinical trials, were included. Two authors independently evaluated the quality of original research publications and extracted data from the studies that met the criteria. RESULTS Around 8 randomized controlled trials involving 1078 patients were included. Reamed intramedullary nailing was associated with shorter time to consolidation of the fracture (SMD = -0.62, 95% CI = -0.89 to -0.35, P < 0.00001), lower secondary procedure rate (OR = 0.25, 95% CI 0.10-0.62, P = 0.003), lower nonunion rate (OR = 0.14, 95% CI = 0.05-0.40, P < 0.01), and lower delayed-union rate (OR = 0.19, 95% CI = 0.07-0.49, P < 0.01) compared to unreamed intramedullary nailing. The 2 groups showed no significant differences in risk of implant failure (OR = 0.50, 95% CI 0.14-1.74, P = 0.27), mortality risk (OR = 0.94, 95% CI 0.19-4.68, P = 0.94), risk of acute respiratory distress syndrome (ARDS; OR = 1.55, 95% CI 0.36-6.57, P = 0.55), or blood loss (SMD = 0.57, 95% CI = -0.22 to 1.36, P = 0.15). CONCLUSION Reamed intramedullary nailing is correlated with shorter time to union and lower rates of delayed-union, nonunion, and reoperation. Reamed intramedullary nailing did not increase blood loss or the rates of ARDS, implant failure, and mortality compared to unreamed intramedullary nailing. Therefore, the treatment of femoral fractures using reamed intramedullary nailing is recommended.

Abstract
PURPOSE To explore the possible surgical factors related with nonunion in femoral shaft fracture following intramedullary nailing. METHODS We retrospectively analyzed totally 425 patients with femoral shaft fracture in level I urban trauma center, including 254 males and 171 females, with an average age of 37.6 (ranging from 21 to 56) years old. The inclusion criteria included: (1) traumatically closed fracture of femoral shaft, with pre- operative films showing non-comminuted fracture, such as transverse fracture, oblique fracture or spiral fracture; (2) closed reduction and fixation with interlocking intramedullary nail at 3-7 days after trauma; (3) complete follow-up data available. The relationship between the following factors (fracture site, reduction degree, direction of nail insertion and nail size) and nonunion was studied. RESULTS The incidence of femoral nonunion was 2.8% in patients with closed simple fracture undergoing interlocking intrameduallary nailing, including 11 cases of hypertrophic nonunion. Nonunion was related significantly to distal fracture, unsatisfactory reduction and unreamed nail (p < 0.05). There was no significant difference between antegrade nail and retrograde nail (p > 0.05). CONCLUSIONS Nonunion in femoral shaft facture following interlocking intramedullary nailing is related to fracture site, fracture reduction and nail diameter. The choice of reamed nails or unreamed nails depends on the fracture site and reduction degree.

Abstract
Periosteal osteosarcoma (POS) is a rare primary malignant bone tumor arising from the surface of long bones. In addition, Marfan's syndrome (MFS) is an infrequent hereditary autosomal dominant connective tissue disorder with high penetrance and variable phenotypes, which primarily affects the ocular, skeletal and cardiovascular systems. The present study reported a case of POS and MFS co-occurring in a child. A 6-year-old girl with MFS presented with pain, swelling and deformity in the right thigh following a fall. The patient was diagnosed with a right femoral shaft fracture and underwent open internal fixation surgery at a local hospital. At 2 weeks following surgery, the patient's parents observed increased swelling in the right thigh and thus, revisited the clinic. X-ray examination revealed extensive osteotylus around the fracture site and the clinician decided to remove the internal fixation. Following removal of the implant, aggravated swelling and superficial venous engorgement were observed. The patient was then admitted to Nanfang Hospital, where magnetic resonance imaging was performed, which identified symptoms of an abnormal periosteal reaction with bone erosion, indicating POS. The patient underwent a wide resection of the tumor and the histopathological examination confirmed the diagnosis of POS. No recurrence was identified at 9 months postoperatively. In conclusion, the present case report may result in increased awareness of the possibility of malignant bone tumors in a hereditary patient with osteotylus overgrowth following fracture surgery; in addition, the present case indicated a possible correlation between POS and MFS.

Abstract
BACKGROUND The treatment for length-unstable diaphyseal femur fractures among school-age children is commonly intramedullary elastic nails, with or without end caps. Another possible treatment is the semi-rigid pediatric locking nail (PLN). The purpose of this biomechanical study was to assess the stability of a length-unstable oblique midshaft fracture in a synthetic femur model stabilized with different combinations of intramedullary elastic nails and with a PLN. METHODS Twenty-four femur models with an intramedullary canal diameter of 10.0 mm were used. Three groups with various combinations of titanium elastic nails (TEN) with end caps and one group with a PLN were tested. An oblique midshaft fracture was created, and the models underwent compression, rotation, flexion/extension, and a varus/valgus test, with 50 and 100 % of the forces generated during walking in corresponding planes. RESULTS We present the results [median (range)] from 100 % loading during walking. In axial compression, the PLN was less shortened than the combination with two 4.0-mm TEN [by 4.4 (3.4-5.4) mm vs. 5.2 (4.8-6.6) mm, respectively; p = 0.030]. No difference was found in shortening between the PLN and the four 3.0-mm TEN [by 7.0 (3.3-8.4) mm; p = 0.065]. The two 3.0-mm TEN did not withstand the maximum shortening of 10.0 mm. In external rotation, the PLN rotated 12.0° (7.0-16.4°) while the TEN models displaced more than the maximum of 20.0°. No model withstood a maximal rotation of 20.0° internal rotation. In the four-point bending test, in the coronal and the sagittal plane, all combinations except the two 3.0-mm TEN in extension withstood the maximum angulation of 20.0°. CONCLUSIONS PLN provides the greatest stability in all planes compared to TEN models with end caps, even though the difference from the two 4.0-mm or four 3.0-mm TEN models was small.

Abstract
PURPOSE Rigid interlocking nailing for femoral shaft fracture is ideal for use in adolescents in terms of stability of the fracture and convenience for the patient. However, numerous authors have reported that rigid interlocking nailing has some limitations in this age group due to the risk of complications. We evaluated the results of intramedullary nailing for femoral shaft fractures with an interlocking humeral nail in older children and adolescents. MATERIALS AND METHODS We retrospectively reviewed records of patients treated with an interlocking humeral nail. Radiographs were examined for proximal femoral change and evidence of osteonecrosis. Outcomes were assessed by major or minor complications that occurred after operative treatment. RESULTS Twenty-four femoral shaft fractures in 23 patients were enrolled. The mean age at the time of operation was 12 years and 8 months and the mean follow- up period was 21 months. Bony union was achieved in all patients without any complications related to the procedure such as infection, nonunion, malalignment and limb length discrepancy. All fractures were clinically and radiographically united within an average eight weeks. No patients developed avascular necrosis of the femoral head and coxa valga. CONCLUSION Intramedullary nailing through the greater trochanter using a rigid interlocking humeral nail is effective and safe for the treatment of femoral shaft fractures in older children and adolescents.

Abstract
This is a prospective study to evaluate the efficacy of the Perkins traction in the treatment of adult femoral shaft fractures from October 1, 2007, to the present at the Black Lion Hospital in Addis Ababa University Hospital in Ethiopia. All femur fractures admitted to the hospital were reviewed and evaluated for treatment. Black Lion Hospital (Tikur Anbessa) is the university hospital in Addis Ababa and the highest tertiary teaching hospital in a country of 85 million inhabitants. A 67-bed orthopedic department offers the main ground for teaching to the undergraduate medical students. The hospital is also the pivotal center for the formation of the orthopedic residents. Patients from different parts of the country are referred to this institution for orthopedic care. A total of 68 adult (older than 16 years) patients with 69 femoral shaft fractures were considered for treatment during the study period. Consent was obtained and prospective treatment initiated. A standard Perkins traction was applied by an orthopedic team composed of consultants, orthopedic residents, physical therapists, and nurses. A protocol was developed for patients undergoing such traction. The physiotherapists will supervise all individual or group therapy sessions. Progressive knee range of motion to facilitate quadriceps and hamstring muscle strengthening exercises were implemented four times a day and recorded. Demographic information, fracture patterns, duration of traction, thigh circumference leg length discrepancy, and pin sites were routinely monitored and charted. Data were computerized and analyzed weekly, and appropriate adjustments were made accordingly. Clinical evidence of a competent callus and confirmation by radiographic studies will influence the cessation of traction to allow gait training with toe-touch crutch ambulation. Progress will be monitored during the following outpatient visits in the fracture clinic. A total of 68 consecutive patients with 69 femoral shaft fractures were treated with the Perkins traction. There were 60 men (88.2%) and only 8 women (11.8%), for a ratio of 8 men to 1 woman. The age of the cohort patient varied between 18 and 28 years. The mechanisms of injury for most of the fractures were motor vehicle accidents, resulting in an isolated femoral shaft fracture in 49.2% of the patients. Half of the fractures were by means of closed injury (n = 44; 64.7%). One patient with a bilateral femoral shaft fracture was also added to the study. The right side was more often involved, with 41 fractures (60%), than the left, with 28 fractures (40%). Most of the fractures involved the proximal third of the femur (n = 34; 50%), but the most common fracture pattern was transverse (n = 29; 42.6%), followed by a comminuted pattern (n = 18; 26.5%). Three segmental fractures were also encountered. The mean hospital stay was 45 days (33 patients; 48.5%), with the length of time in traction varying from 30 to 40 days. Only 2 patients remained in traction for a period of 60 days. At the end of the traction period, 8 patients (11.8%) showed a decrease in the quadriceps mass, and 7 patients (10.3%) showed stiffness of the knee with a range of motion limited to 0° to 90°. Most patients were discharged after about 8 months of treatment. One patient suffered a nonunion, and one was malunited. Superficial pin care infections were noted in 8 patients (11.8%) and treated appropriately. The conservative treatment of 69 femoral shaft fractures using the Perkins traction at Black Lion University Hospital in Addis Ababa, Ethiopia, has been proven to be a safe and effective method. It should be encouraged in countries like ours where it is a luxury to have a C-Arm in the operating room and where the hardware often is not available to perform a stable stabilization of the long bone fractures.
