Abstract
Objective To investigate current practices among orthopaedic trauma surgeons in treating geriatric distal femur fractures and evaluate current postoperative weight-bearing recommendations. Methods A 26-question survey was emailed to Major Extremity Trauma Research Consortium surgeon members to characterize current practice with different fixation methods for distal femur fractures and the surgeon-directed postoperative weight-bearing recommendations for each approach. Results Surveys were completed by 123 orthopaedic trauma surgeons with a response rate of 37% (123/332). Retrograde intramedullary nailing (IMN) was commonly performed by 88% of surgeons, and lateral locked plate was commonly performed by 74% of surgeons. Retrograde IMN with a lateral plate was commonly performed by 51% of surgeons. Dual femoral plating was commonly performed by 18% of surgeons and sometimes performed by 39% of surgeons. Surgeons were significantly more likely to allow immediate postoperative weight-bearing for retrograde IMN (P < 0.001), retrograde IMN with lateral plate (P < 0.001), and dual plate (P < 0.001) as compared with locked lateral plate. Most surgeons (79%) would be interested in participating in a randomized controlled trial (RCT) investigating single implant versus dual implant for distal femur fractures and believe that a trial incorporating immediate weight-bearing is important. Conclusion A variety of implants are commonly used to treat geriatric distal femur fractures. Patients with distal femur fracture commonly have weight-bearing restrictions in the immediate postoperative period. A large proportion of orthopaedic trauma surgeons have clinical equipoise for an RCT to investigate the impact of surgical construct and weight-bearing on geriatric distal femur fracture patient recovery.

Abstract
Dual plating of comminuted distal femoral fractures allows for early patient mobilization. An additional helically shaped medial plate avoids the medial vital structures of the thigh. The aim of this study is to investigate the biomechanical competence of an augmented lateral locking compression plate distal femur (LCP-DF) using an additional straight versus a helically shaped medial LCP of the same length. Ten pairs of human cadaveric femora were instrumented with a lateral anatomical 15-hole LCP-DF. Following, they were pairwise instrumented with either an additional medial straight 14-hole LCP (group 1) or a 90°-helical shape LCP (group 2). All specimens were biomechanically tested under quasi-static and progressively increasing combined cyclic axial and torsional loading until failure. Initial interfragmentary axial displacement and flexion under static compression were significantly smaller in group 1 (0.11 ± 0.12 mm and 0.21 ± 0.10°) versus group 2 (0.31 ± 0.14 mm and 0.68 ± 0.16°), p ≤ 0.007. Initial varus deformation under static compression remained not significantly different between group 1 (0.57 ± 0.23°) and group 2 (0.75 ± 0.34°), p = 0.085. Flexion movements during dynamic loading were significantly bigger in group 2 (2.51 ± 0.54°) versus group 1 (1.63 ± 1.28°), p = 0.015; however, no significant differences were observed in terms of varus, internal rotation, and axial and shear displacements between the groups, p ≥ 0.204. Cycles to failure and load at failure were higher in group 2 (25,172 ± 6376 and 3017 ± 638 N) compared to group 1 (22,277 ± 4576 and 2728 ± 458 N) with no significant differences between them, p = 0.195. From a biomechanical perspective, helical double plating may be considered a useful alternative to straight double plating, demonstrating ameliorated damping capacities during flexion deformation and safer application as the medial neurovascular structures of the thigh are avoided.

Abstract
OBJECTIVE This study was performed to evaluate the effectiveness of intramedullary nailing and a lateral locking plate combined with the reamer-irrigator-aspirator (RIA) bone grafting technique for resistant distal femoral nonunion. METHODS This retrospective observational study was performed from January 2018 to December 2021 and involved five patients who presented with resistant distal femoral nonunion despite undergoing several surgeries. They were treated with intramedullary nailing and a lateral locking plate combined with the RIA bone grafting technique. Postoperative follow-up was performed to observe the healing time, and functional outcomes were evaluated using the Lower Extremity Functional Scale (LEFS). RESULTS After the patients had been monitored for a mean of 17.9 months, complete bone healing was observed in every patient (mean healing time of 4.8 months). Postoperative wound failure in an older patient was successfully treated with resuturing and nutritional assistance. At the last follow-up, the mean LEFS score was 71.2/80 and the mean knee flexion was 109 degrees. CONCLUSIONS Our study demonstrates that combining intramedullary nailing and a lateral locking plate with the RIA bone grafting technique enhances biological properties, provides good structural support, and achieves good union and functional results in the management of resistant nonunion of the distal femur.

Abstract
Background and objective Intra-articular fractures of the distal femur pose a significant surgical difficulty. These fractures are challenging to repair, and surgery is frequently advised for a successful outcome. The distal femoral fractures make up between 4-6% of all femoral fractures and account for less than 1% of all fractures. When compared to the single screw's axial stiffness or pullout resistance, as is the case with unlocked plates, the locking compression plate (LCP) is a single beam construct whose strength of fixation is equal to the sum of all screw-bone contacts. Against this backdrop, the current study was conducted for evaluating the functional outcomes of distal femoral fractures treated with LCP fixation. Methodology We conducted an observational study at a tertiary care facility in Kolar spanning a period of three years, from January 2019 to January 2022. We included all patients aged more than 18 years, who were diagnosed with distal femoral fractures [only those classified as type C according to the AO Foundation/Orthopedic Trauma Association (AO/OTA) classification]. Patients with terminal illnesses, revision of previous surgery, fractures with neurovascular injuries, and those diagnosed with pathological fractures were excluded from the study. The included patients were treated by LCP and discharged on postoperative day 10 after suture removal. The first follow-up was at the first month and subsequent follow-ups were done at three and six months, and the functional outcomes were assessed by using Neer's score for straight leg raises. Radiographs with fading fracture lines and callus formation on three-fourths of the cortices were regarded as indicators of fracture healing. Results Among the 30 study participants, 80% were males. The mean time for the radiological union was 15 weeks. In this study, there were no instances of infection or angular deformity greater than 5 degrees. About 80% of the study participants had ranges of motion (ROM) above 120 degrees at the end of the six-month follow-up period; 12 cases had an excellent score (40%), 15 cases (50%) had a satisfactory score, two cases (6.7%) had an unsatisfactory score, and only one case had poor score. Common complications observed were excessive bleeding, difficulty in reduction, superficial infections, and knee stiffness. Conclusion For patients with distal femoral fractures, the LCP treatment can result in good functional and radiological outcomes with fewer complications.

Abstract
For complex distal femoral fractures, a single lateral locking compression plate or retrograde intramedullary nail may not achieve a stable environment for fracture healing. Various types of double fixation constructs have been featured in the current literature. Double-plate construct and nail-and-plate construct are two common double fixation constructs for distal femoral fractures. Double fixation constructs have been featured in studies on comminuted distal femoral fractures, distal femoral fracture with medial bone defects, periprosthetic fractures, and distal femoral non-union. A number of case series reported a generally high union rate and satisfactory functional outcomes for double fixation of distal femoral fractures. In this review, we present the state of the art of double fixation constructs for distal femoral fractures with a focus on double-plate and plate-and-nail constructs.

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
Knee fractures often require open reduction internal fixation (ORIF) for knee function recovery. More than one fifth of patients with knee fractures subsequently develop posttraumatic arthritis, and over 5% of them need total knee arthroplasty (TKA). We conducted this nationwide retrospective cohort study using the data of 2,000,000 people in the general population who received TKA and were followed up in the 17-year period 2001-2017, through random sampling of the Taiwan National Health Insurance Research Database. We matched the ORIF and non-fracture groups by a propensity score, based on age, sex, index date of surgery, and comorbidities enrolled in CCI calculated at a 1:1 ratio. The average proportion of subjects receiving TKA after ORIF for distal femoral or proximal tibial fractures was 2.0 per 1000 person-years, which was significantly higher than that in the non-fracture group. Patients aged 20-65 years and males represented a significantly higher proportion of subjects receiving TKA after ORIF than that in the non-fracture group. The proportion of subjects receiving TKA for the 20-65-year subgroup of the ORIF group was 4%, and that for the male subgroup was 1.5%; both rates increased over the 17-year follow-up period. More aggressive intraoperative and postoperative adjuvant therapies may be necessary for these subgroups.

Abstract
Background and Objectives: The proximity of the popliteal vessels in the distal femur may increase the risk of iatrogenic vascular injury during cerclage wiring. In this study, the closest location and distance of the popliteal vessels to the femur was examined using magnetic resonance imaging (MRI). The associations between anthropometric factors and the distance that would guide the placement of wires safely during surgery were also identified. Materials and Methods: We reviewed adult knee magnetic resonance images and recorded: (1) the relation and the shortest horizontal distance (d-H) from the femoral cortex to the popliteal vessels in axial images and (2) the vertical distance (d-V) from the adductor tubercle to the axial level of the d-H values in coronal images. The effects of anthropometric factors (sex, age, body height, body weight, body mass index, thigh circumference, femoral length and femoral width) on these distances were analysed. Results: Analysis of 206 knee magnetic resonance images revealed that the closet locations of popliteal vessels were at the posteromedial aspect of the femur. The d-H and d-V were 7.38 ± 3.22 mm and 57.01 ± 11.14 mm, respectively, and were both shorter in women than in men (p < 0.001). Multivariate analysis identified thigh circumference and femoral length as the most influential factors for the d-H and d-V, respectively (p < 0.001). Linear regression demonstrated a strong positive linear correlation between the thigh circumference and the d-H and between the femoral length and the d-V (Pearson’s r = 0.891 and 0.806, respectively (p < 0.001)). Conclusions: The closet location and distance of the popliteal vessels to the femur provide useful information for wire placement during distal femoral fracture surgery while minimising the risk of vascular injury. Given that patients with a smaller thigh circumference and a shorter femoral length are more likely to have a smaller d-H and a shorter d-V, respectively, cautious measures should be taken in such cases.

Abstract
PURPOSE We aimed to determine the efficacy of cerclage wiring by comparing the clinical and radiological results between internal fixation with locking plates after distal femoral fracture reduction with or without cerclage wiring. MATERIALS AND METHODS One hundred and one patients who received open reduction internal fixation for distal femoral fractures of oblique, spiral, and spiral wedge type between 2007 and 2014 were reviewed retrospectively. Only locking plate fixation was performed in 46 patients, and locking plate fixation with additional cerclage wiring was performed in 55 patients (Group CW). Demographic, clinical, and radiologic factors were evaluated in both the groups. Age, gender, bone mineral density, bone graft, and the presence of concomitant fractures were measured as demographic factors. The range of motion of knee joint, Lysholm knee score, visual analog scale score, procedure time, and C-arm time were measured as clinical factors preoperatively and at the final followup. We also evaluated the duration of bone union and knee joint alignment radiologically. RESULTS There were no demographic differences between the two groups. Furthermore, there were no statistically significant differences between the two groups in terms of clinical and radiological parameters. However, the procedure time used was significantly longer in Group LP than in Group CW (108.4 vs. 95.2 min; P = 0.027). The C-arm time was longer in Group LP (2.8 vs. 1.2 s; P = 0.017). CONCLUSIONS Open reduction and locking plate fixation with additional cerclage wiring is a useful method for the reduction of complicated distal femoral fractures, without increased complications such as nonunion. LEVEL OF EVIDENCE Level III, retrospective cohort design, treatment study.

Abstract
There remains a lack of data on the epidemiological characteristics of surgical site infection (SSI) following the open reduction and internal fixation (ORIF) of intra-articular fractures of distal femur, and the aim of this study was to solve this key clinical issue. The electronic medical records (EMRs) of patients who underwent ORIF for distal femoral fracture from January 2013 to December 2017 were reviewed to identify those who developed a SSI. Then, we conducted univariate Chi-square analyses and used a multivariate logistic regression analysis model to determine the adjusted risk factors associated with SSI. A total of 724 patients who underwent ORIF of intra-articular fractures of the distal femur were studied retrospectively, and 29 patients had postoperative SSIs. The overall incidence of SSIs was 4.0% (29/724), with deep SSIs being 1.5% (11/724), and superficial SSIs being 2.5% (18/724). Staphylococcus aureus was the most common causative pathogen (8, 42.1%), followed by mixed bacterial pathogens (5, 26.3%). Open fracture, obesity, smoking, and diabetes mellitus were identified as the adjusted risk factors associated with SSIs. Although modification of these risk factors may be difficult, patients and families should be counselled regarding their increased risk of SSI because these patients potentially benefit from focused perioperative medical optimisation.

Abstract
INTRODUCTION Distal femoral fractures in elderly population had recorded an increase in incidence in the last 2 decades. Lateral distal femoral locking plating is considered one of the best options especially when dealing with comminuted fractures but varus collapse of the medial femoral condyle occurs frequently in patients with osteoporosis. Anatomical reduction of the fracture with stable rigid fixation using double-plating approach allows early mobilization of geriatric population and prevents varus collapse minimizing the comorbidities in such fractures. PATIENTS AND METHODS Between September 2014 and January 2017, a prospective study on 23 patients with comminuted osteoporotic distal femoral fractures managed through the double-plating approach through a single parapatellar approach has been conducted. Only osteoporotic geriatric patients with isolated distal femoral fractures were included. Polytraumatized, open fractures, and fracture type 33-A1, 33-A2, and 33-B were excluded. The mean age was 69.6 years (61-80). All patients have been evaluated as regard duration of procedure, time to union, EQ-5D-5L score, the need of autologous bone grafts, range of knee motion, and presence of complications. RESULTS The average follow-up was 14.1 months. The majority of fractures were type 33-C2 (13 patients). Average procedure time was 148 minutes (117-193 minutes). Mean EQ-5D-5 L score was 83.8 (72-82). Average time to union was 9 months (3-12 months). Four (17.4%) cases needed autologous bone graft after 6 months. No loss of reduction in any of the cases was evident, although 6 (26%) cases had screw breakage or cutout in one of the plate fixation. Two (8.7%) patient developed superficial wound infection and 1 (4.3%) developed DVT. DISCUSSION This study aimed at evaluation of the success of double plating of distal femoral fractures in geriatric population. different fixation methods were studied for reduction and fixation of such a fracture such as external fixation, intramedullary nails and lateral plating. the quality of fracture reduction, functional and radiological outcomes, time to union, the need for bone grafting and complication are the main debatable issues. CONCLUSION Single-incision double-plating approach for distal femoral osteoporotic fractures is effective and provides stable construct without reduction loss allowing early rehabilitation. Delayed union and the need for bone graft are the major drawbacks for this technique.

Abstract
INTRODUCTION The Less Invasive Stabilisation System (LISS) is an angle-stable plate that enables treatment of distal femoral comminuted and periprosthetic fracture. As it is placed through a minimally-invasive lateral approach, lateral knee pain is a commonly described symptom after its application. This study investigates knee lateral collateral ligament (LCL) iatrogenic injury during LISS plate fixation. A cadaver study was performed and a retrospective radiological investigation with the analysis of its clinical application was conducted to evaluate possible knee LCL damage. METHODS The cadaver study included 13 human lower extremities, treated with LISS. After application, lateral knee side was dissected, implants were removed and distances between the drill holes and LCL origin were measured. In the retrospective radiological evaluation, postoperative X-rays for patients treated with distal femoral LISS plate in the University Hospital Regensburg, Germany from January 2010 to December 2015 were examined. Following a protocol described by Pietrini et al., the LCL origin on postoperative X-rays was calculated, both in lateral and anterior-posterior (AP) view, and distances between the plate and its closest locking screw to the LCL origin were measured. RESULTS In the cadaver study, the mean distance between the closest drilling hole and the ligament origin was 14.0mm (range 9-21mm; SD 3.8mm). Twenty-two patients matched the inclusion criteria for the retrospective radiological study. In lateral view, the mean distance between the origin and the closest locking screw was 6.3mm (range 0-16.4mm; SD 4.7mm); the mean distance between the origin and the plate was 3.1mm (range 0-13.9mm; SD 4.1mm). In AP view, the mean distance between LCL origin and the nearest screw was 2.4mm (range 0-7.6mm; SD 2.4mm). The mean distance between the origin and the most distal locking screw was 9.2mm (range 0-17.5mm; SD 4.0mm). DISCUSSION The LISS is a safe option to treat distal femoral fractures in respect to the LCL. Due to close proximity, the LCL might be harmed; therefore, lateral knee pain or lateral instability after implantation should be assessed in further treatment.

Abstract
A computer-aided 3-dimensional (3D) visualization operation simulation system based on computer-aided design (CAD) Unigraphics NX and Mimics software was established to provide orthopedic surgeons with an actual and reliable system in treating of distal femoral fracture.According to the preoperative CT data, 3D reconstruction of the distal femoral fracture could be achieved by the Mimics software. Then, the CAD Unigraphics NX software was used to measure the model function of all the related surgical instruments, including less invasive stabilization system (LISS) and retrograde intramedullary nail fixation.The function of CAD Unigraphics NX and Mimics software was successful in assisting in the treatment of distal femoral fracture with LISS and retrograde intramedullary nail fixation. The operation procedure was actual, visualized, and lifelike. Moreover, the operation effect could be estimated before surgery.The virtual surgery system may improve the reliability and safety of the operative care of distal femoral fracture.

Abstract
BACKGROUND Although the method has been used widely, one of the greatest challenges for intramedullary nailing is to position the distal locking screw. A new technology, the electromagnetic navigation system, is a radiation-free way to locate the position of the drill bit and provide 3-dimensional real-time feedback of location and orientation of the drill bit relative to the locking holes. The purpose of our study was to evaluate the reliability and efficiency of the free-hand technique compared to the new electromagnetic navigation system. METHODS Fifty-four patients with femoral fracture who needed treatment with intramedullary nails were divided into 2 groups. One group including 26 patients underwent distal locking using the standard free-hand method, whereas the electromagnetic navigation system was used with the other 29 patients. Intraoperative fluoroscopy exposure times, screw insertion times, and healing times were recorded; these parameters were used for comparison between the 2 groups. RESULTS There were 17 males and 9 females who had femoral intramedullary nails using the free-hand technique, whereas 21 males and 8 females received intramedullary nails using the electromagnetic navigation system. The mean time of distal locking was 19.5 ± 6.0 minutes in the free-hand (FH) group, whereas the time was 6.1 ± 1.4 minutes in the electromagnetic (ET) group. The exposure time for the FH group was 26.8 ± 13.3 seconds and 2.2 ± 1.1 seconds for the ET group. Healing time proved to be comparable in the FH and ET groups (16.4 ± 3.7 weeks vs 15.1 ± 2.8 weeks). CONCLUSION Under the premise of achieving the same effect, the electromagnetic navigation system has the advantage of less distal locking time and less radiation dose.

Abstract
OBJECTIVE The purpose of this study was to retrospectively evaluate the use of locked plating (LP) and retrograde nailing (RN) for treating extra-articular distal femoral fractures. MATERIALS AND METHODS From January 2004 to March 2009, 36 patients with extra-articular distal femoral fractures were surgically treated at our Trauma Center. The patients were divided into two groups according to the treatment method, with 19 patients being treated by LP (LP group) and 17 patients via RN (RN group). RESULTS The demographics of age (p = 0.460) and gender (p = 0.481) in both LP and RN groups were similar. No differences were found with respect to postoperative malreduction, deep infection, hardware failure, operating time, knee pain, HSS score and range of knee movement. The mean intraoperative blood loss was significantly higher in the RN group (298 ± 65.2 ml, range 200-410) than in the LP group (200 ± 48.9 ml, range 130-300) (p < 0.01). However, a higher rate of union disturbance was observed in the LP group (36.8%) compared to the RN group (5.9%) (p = 0.044). CONCLUSIONS The overall union disturbance rate in the LP group was higher than in the RN group. However, further analysis revealed that clinical outcome may largely depend on surgical technique rather than on the choice of implant. Therefore, correct rules (the same for every procedure) should be strictly adhered to, especially in the application of LP.
