Abstract
OBJECTIVE To report the outcomes of 15 dogs and two cats with metabone fractures treated with fluoroscopically guided normograde metabone pinning (FGNMP). STUDY DESIGN Retrospective case series. ANIMALS A total of 15 client owned dogs and two cats with 57 metabone fractures. METHODS Description of FGNMP and reporting of the following data: signalment, pre- and postoperative radiographs, intramedullary pin diameter used, anesthesia, surgery and coaptation times, duration to normal weightbearing and bone union, postoperative care and complications. RESULTS Median surgery time was 54 min (range: 26-99), median duration of coaptation was 14 days (range: 1-5 weeks), median time to normal weightbearing was 16 days (range: 2-45) and median time to bone union was 6 weeks (range: 4-12). All cases had at least 12 months of post-surgical follow-up with a median follow-up of 18 months (range: 12-70). No major complications occurred. Mild radiographic changes associated with subchondral bone sclerosis were noted on follow-up radiographs in 13/57 fractures. All cases returned to normal gait and full (15) or acceptable (2) function. CONCLUSION In this study, FGNMP was an effective and safe technique for metabone fracture repair, requiring only short-term external coaptation in most patients. Time to bone union and return to normal function compared favorably to previously reported techniques. CLINICAL RELEVANCE Fluoroscopically guided normograde metabone pinning provides an alternative technique for treatment of metabone fractures.

Abstract
PURPOSE To describe the surgical technique and the outcome of a case series of comminuted intra-articular distal femur fractures (AO/OTA 33C) treated with a nail-plate combination (NPC) implant. METHODS We retrospectively analyzed a case series of 14 patients with comminuted intra-articular distal femur fractures (DFF) treated with an intramedullary retrograde nail in combination with a lateral low-contact condylar locking plate, in a period between June 2020 and January 2023 at a Level 1 trauma center. Baseline demographic and clinical data were recorded. Time to bone healing, function using Schatzker Lambert Score, and complications were documented. RESULTS Fourteen patients, 8 males and 6 females, with a total of 15 NPC implants, were included in this study. Eight out of 14 patients had open fractures, all with a Gustilo Anderson type IIIA exposure. The mean age was 48.5 ± 18.05 years. The median follow-up was 392 days, with only one patient lost to follow-up. 11 out of 15 implants achieved complete radiographic consolidation during follow-up, at a mean of 5.40 ± 1.07 months. At the 12-month follow-up, all patients could fully bear weight painlessly or with mild pain. Schatzker Lambert Score was excellent for 4 patients, good for 2 patients, fair for 5 patients, and failure for 2 patients. The main postoperative complications were rigidity (3 cases), limb shortening (2 cases), and septic non-union (1 case). CONCLUSION This study suggests that the nail-plate combination (NPC) may provide a more effective surgical technique for addressing the challenges associated with comminuted intra-articular distal femur fractures (AO/OTA 33C).

Abstract
INTRODUCTION Fracture reduction and fixation of distal femur fractures are technically demanding. Postoperative malalignment is still commonly reported after minimally invasive plate osteosynthesis (MIPO). We evaluated the postoperative alignment after MIPO using a traction table with a dedicated femoral support. METHODS The study included 32 patients aged 65 years or older with distal femur fractures of all AO/OTA types 32 (c) and 33 (except 33 B3 and C3) and peri-implant fractures with stable implants. Internal fixation was achieved with MIPO using a bridge-plating construct. Bilateral computed tomography (CT) scans of the entire femur were performed postoperatively, and measurements of the uninjured contralateral side defined anatomical alignment. Due to incomplete CT scans or excessively distorted femoral anatomy, seven patients were excluded from analyses. RESULTS Fracture reduction and fixation on the traction table provided excellent postoperative alignment. Only one of the 25 patients had a rotational malalignment of more than 15° (18°). CONCLUSIONS The surgical setup for MIPO of distal femur fractures on a traction table with a dedicated femoral support facilitated reduction and fixation, resulting in a low rate of postoperative malalignment, despite a high rate of peri-implant fractures, and could be recommended for surgical treatment of distal femur fractures.

Abstract
OBJECTIVES The 2 main forms of treatment for distal femur fractures are locked lateral plating and retrograde nailing. The goal of this trial was to determine whether there are significant differences in outcomes between these forms of treatment. DESIGN Multicenter randomized controlled trial. SETTING Twenty academic trauma centers. PATIENTS/PARTICIPANTS One hundred sixty patients with distal femur fractures were enrolled. One hundred twenty-six patients were followed 12 months. Patients were randomized to plating in 62 cases and intramedullary nailing in 64 cases. INTERVENTION Lateral locked plating or retrograde intramedullary nailing. MAIN OUTCOME MEASUREMENTS Functional scoring including Short Musculoskeletal Functional Assessment, bother index, EQ Health, and EQ Index. Secondary measures included alignment, operative time, range of motion, union rate, walking ability, ability to manage stairs, and number and type of adverse events. RESULTS Functional testing showed no difference between the groups. Both groups were still significantly affected by their fracture 12 months after injury. There was more coronal plane valgus in the plating group, which approached statistical significance. Range of motion, walking ability, and ability to manage stairs were similar between the groups. Rate and type of adverse events were not statistically different between the groups. CONCLUSIONS Both lateral locked plating and retrograde intramedullary nailing are reasonable surgical options for these fractures. Patients continue to improve over the course of the year after injury but remain impaired 1 year postoperatively. LEVEL OF EVIDENCE Therapeutic Level I.

Abstract
PURPOSE Nonunion is the most frequent cause of reoperation and is associated with high morbidity after distal femur fracture (DFF). We examined the rates of nonunion requiring reoperation after fixation for DFF using a locking compression plate (LCP) or retrograde intramedullary nail (RIMN). METHODS We included four studies comparing LCP and RIMN and 38 single-cohort studies reporting LCP or RIMN. In total, 2156 femurs were included and 166 non-unions were detected. We conducted a pair-wise meta-analysis (with a fixed-effects model) on the four comparative studies and a proportional meta-analysis on the 38 articles to estimate the nonunion rate. We performed sensitivity analysis by comparing studies using LCP with less invasive surgical systems (LISS) with those that used RIMN. RESULTS The pairwise meta-analysis showed a similar nonunion rate between the groups [odds ratio: 1.02; 95% confidence interval (CI) 0.94-1.11, p = 0.633]. According to proportional meta-analysis, the pooled prevalence of nonunion was 5% (95% CI 4-7) totally, 6% (95% CI 4-8) in the LCP group, and 4% (95% CI 2-6) in the RIMN group (heterogeneity: p = 0.105). According to the sensitivity analysis, there was no difference in the union rate. The pooled prevalence of nonunion from sensitivity analysis was 4 % (95% CI, 3-5); it was 4% (95% CI, 3-6) in LCP with LISS and was 4% (95% CI, 2-6) in RIMN group (heterogeneity: p = 0.941). CONCLUSION Approximately 5% of patients who underwent LCP or RIMN fixation developed nonunion. Therefore, LCP and RIMN are effective DFF techniques and mastering one of them is essential.

Abstract
OBJECTIVE To investigate an association between a surgeon's choice of a cephalomedullary nail (CMN) or sliding hip screw (SHS) with the cost of treating a pertrochanteric hip fracture. DESIGN Multicenter retrospective cohort study. SETTING US Veterans Health Administration Sierra Pacific Network. PATIENTS/PARTICIPANTS Two hundred ninety-four consecutive US veterans admitted for a principal diagnosis of an OTA/AO 31A-type pertrochanteric hip fracture of a native hip from 2000 to 2015. INTERVENTION Internal fixation using a CMN or an SHS. MAIN OUTCOME MEASUREMENTS Veterans Administration Health Economic Resource Center average national cost estimate of combined acute and postacute care episode cost, excluding implant cost, normalized to 2015 US dollars by the Consumer Price Index. RESULTS Median episode cost was $8223 lower with a CMN than an SHS (95% confidence interval, $5700-$10,746, P < 0.001) after matching on a propensity score for treatment with a CMN based on age, sex, body mass index, Charlson Comorbidity Index, fracture characteristics, study site, and admission year. A subgroup propensity-matched analysis excluding reverse obliquity pertrochanteric fractures was not sufficiently powered to detect a difference in episode cost (β = 0.76, P = 0.311). CONCLUSIONS Implant choice significantly affected the episode cost of care of hip fracture at Veterans Health Administration facilities. LEVEL OF EVIDENCE Economic Level IV.

Abstract
IMPORTANCE Surgical management of periarticular knee fractures can be challenging, and adverse outcomes may be severe. Recent literature indicates that the rate of periarticular knee surgical site infection (SSI) may range from 2% to 88% depending on the fracture site. OBJECTIVE To examine the prevalence of deep SSI and the rate of septic arthritis after surgical repair of fractures around the knee. DATA SOURCES The electronic databases MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials were searched from their inception to July 1, 2018. STUDY SELECTION Eligible studies had to specifically report deep SSI rates and include fractures in the distal femur, patella, tibial plateau, or proximal tibia. Risk factors that were associated with increased the risk of deep SSI were also examined. DATA EXTRACTION AND SYNTHESIS This study followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline. Data were extracted by multiple investigators. Comprehensive Meta-Analysis software was used for the pooling of data, using either random-effects or fixed-effects models, with respect to the degree of statistical heterogeneity present. Data analyses were conducted in October 2019. MAIN OUTCOMES AND MEASURES The primary outcome was overall prevalence of deep SSI after periarticular knee fracture repair. The secondary outcomes were the overall prevalence of septic arthritis, risk factors associated with deep SSI, and the most commonly cultured bacteria specimens found periarticular knee infections. RESULTS Of 6928 articles screened, 117 articles met inclusion criteria and were included in analysis. Among 11 432 patients included in analysis, 653 patients (5.7%) experienced deep SSIs, most commonly among patients with proximal tibia fractures (56 of 872 patients [6.4%]). Among studies that included information on septic arthritis, 38 of 1567 patients (2.4%) experienced septic arthritis. The 2 most commonly reported bacteria were methicillin-resistant Staphylococcus aureus, found in 67 SSIs, and methicillin-susceptible S aureus, found in 53 SSIs. Sixty-two studies (53.0%) in the sample received a Coleman Methodological Score of poor (<50 points). CONCLUSIONS AND RELEVANCE Deep SSIs occurred in nearly 6% of periarticular knee fracture repairs, and 2.4% of SSIs were associated with septic arthritis. Surgeons managing these injuries should be vigilant when wounds are not pristine. Efforts should be made to elevate the quality of research conducted not only in this subject but also in orthopedic surgery as a whole.

Abstract
INTRODUCTION The current study aimed to retrospectively analyze locked plating (LP) and antegrade intramedullary nailing (AIN) for the treatment of extra-articular distal femoral fractures. PATIENTS AND METHODS Between January 2000 and March 2015, 97 patients (49 male, 48 female) underwent surgery for extra-articular distal femoral fractures in our clinic. Patients were grouped based on their method of treatment (69 (71.1%) with locked plate (LP group) and 28 (28.9%) with antegrade intramedullary nailing (AIN group)), and the groups were analyzed with regards to fracture types, associated trauma, hospital stay, Injury Severity Score (ISS), nonunion, reoperation rate and Lysholm Functional Knee Score. RESULTS The LP and AIN groups had no significant differences with regards to age and gender. Sixteen patients (16.4%) experienced nonunion; all of these (5 (5.1%) in the AIN group and 11 (11.3%) in the LP group) required a secondary procedure (p = 0.773). ISS was significantly higher in the AIN group (p = 0.033). There were no significant differences between the two groups with regards to hardware failure, postoperative malreduction, reoperation rate, deep infection, and nonunion. However, the AIN group (mean 88) had a significantly higher Lysholm Functional Knee Score than the LP group (mean 75.9) (p = 0.019). CONCLUSION In our study we encountered less nonunion in AIN group. Both fixation methods offer good results; however, functional outcomes in the AIN group were significantly better than those in the LP group.

Abstract
We report a series of seven cases of fractures of the distal end of the femur treated by retrograde centro-medullary nailing in the Orthopedic-Trauma Department at the Hospital Ibn Sina over the period 30/05/2010 - 30/04/2015. The average age of patients was 54 years, with a slight male predominance (57,1%). Road traffic accidents were the main cause of these fractures (71.4%) and they mostly affected the right side of body (57,1%). From a surgical point of view, the mean time between symptom onset and treatment initiation was 2 days. Spinal anesthesia was performed in five cases. The average length of stay in hospital was 5 days. The mean time of consolidation was 4 months in all patients, there was only one case of delayed consolidation (6 months). Patients had good functional outcomes with mean knee flexion 120°, with only one case of limited flexion 90°. There was one case of consolidation delay and one case of pseudarthrosis. No deaths, or superficial or deep sepsis, or thromboembolic complications or fat embolism were registered. In general we had satisfactory outcomes. Our study highlights that retrograde femoral nailing is an essential osteosynthesis technique for the surgical treatment of the distal femur fractures.

Abstract
BACKGROUND The number of elderly patients sustaining long bone fractures is increasing with the rise of elderly population in the western world. Management of distal femur fractures is particularly difficult due to osteoporosis and other associated comorbidities. The key to management would be by surgical stabilization, which allows early mobilization. This study was devised to look into the radiological outcome and complication rate in a series of elderly patients who were treated with retrograde nail using spiral locking blade system for extra articular distal femur fractures. MATERIALS AND METHODS This is a retrospective study of patients who have undergone retrograde nailing with spiral-locking blade for distal femoral fractures (extra articular) above the age of 70 years in a major trauma center from 2001 to 2015. Notes were assessed for postoperative complications; time to union and final postoperative followup radiographs were assessed for alignment using a scoring system. RESULTS Forty one patients with an average age of 80 years and an average followup period of 9 months were included. The mean radiological score at final followup was 10.34 (range 8-12), with no significant shortening in any of the patients. Thirty patients had excellent radiological score (>10) and 11 patients scored good (8-9). The difference in time to union between Group 1 - simple fracture pattern (3.42 months) and Group 2 - complex comminuted fracture pattern (4.74 months) was not statistically significant (P = 0.072). There were five delayed unions but no cutout or metal work failure. CONCLUSION The retrograde femoral nail with distal spiral-locking blade system can be a good surgical option for the treatment of extra articular distal femoral fractures in the elderly with the possibility of early weightbearing.

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
The aim for this review is to present general considerations in relation to malalignment after osteosynthesis with plate fixation and its consequences after fractures in adults in each of the following anatomical locations: humerus, forearm, femur, tibia. Recommendations for accepted malalignment in humerus diaphyseal fracture is varus <20 degrees, valgus <15 degrees, sagittal deformity <5 degrees and rotation <30 degrees. Recommendations when treating fractures of the forearm is anatomical reduction. Varus of ulna leads to loss of pronation. Valgus of ulna leads to loss of both pronation and supination. Recommendations for acceptable malalignment in femoral fractures is rotational deformity <15 degrees, increasing varus deformity in intertrochanteric fractures increases load on implant. Cortical-step-sign, profile of lesser trochanter, evaluation of ipsilateral neck anteversion are intraoperative methods to avoid rotational malalignment. Recommendations for accepted malalignment in the tibia is shortening <10mm, varus/valgus <5 degrees, sagittal deformity <10 degrees. Fixation of fibula leads to less rotational and valgus malalignment, but not enough to affect union rate of tibia, complications rate or functional score at 12 months. To avoid malalignment in plating, pre-contoured anatomical plates are available from most manufactures. Being aware that most such plates fit a 50-percentile Caucasian population is important in pre-surgical planning. Evaluation of the contralateral bone and the characteristics of the plate may help in planning additional bending of pre-shaped plates and bending tools should always be available when applying a plate, even a so-called anatomical one.

Abstract
INTRODUCTION Although minimally invasive plate osteosynthesis (MIPO) is a preferred operative treatment for fractures of the distal femur, malalignment is a significant concern because of indirect reduction of the fracture. The purpose of this study, therefore, was to evaluate radiologic alignment after MIPO for distal femoral fractures. PATIENTS AND METHODS Of the 138 patients with fracture of the distal femur who underwent MIPO, we enrolled 51 patients in whom bilateral rotational alignment could be assessed by postoperative computed tomography (CT). The patients included 32 men and 19 women, with a mean age of 54.3 years. Thirteen patients had femoral shaft fractures (according to the AO/OTA classification: 32-A, n=2; 32-B, n=6; 32-C, n=5), whereas 38 patients had distal femoral fractures (33-A, n=7; 33-C, n=31). Coronal and sagittal alignments were assessed using simple radiography, whereas rotational alignment was assessed using CT. According to the difference between the affected and unaffected sides, we divided the patients into satisfactory and unsatisfactory groups (reference point of 8°, using Handolin's classification). Thereafter, we determined which factors can lead to malalignment, including fracture location (distal femoral shaft fracture or metaphyseal fracture), fracture pattern (simple fracture, n=15; complex fractures, n=36 patients), coronal and sagittal alignments, and combined ipsilateral long bone fractures. RESULTS Coronal and sagittal alignment were satisfactory in 96.2% (average, 2.8°) and 98% (average, 2.2°), respectively, whereas the rotational alignment was satisfactory in 56.9% of patients. Leg length discrepancy was satisfactory in 92.3% of the patients (average, 10.9mm). Concerning rotational malalignment, an unsatisfactory result was obtained in 48.6% of subjects with complex fractures and 26.7% of subjects with simple fractures (p=0.114). No significant correlation was noted between the angular deformity in the coronal and sagittal planes and the degree of rotational alignment (p=0.607 and 0.774, respectively). CONCLUSIONS Regardless of the fracture pattern, rotational malalignment may occur at an extremely high rate after MIPO for fractures of the distal femur.

Abstract
Arthrofibrosis after periarticular fractures can create clinically significant impairments in both the upper and lower extremities. The shoulder, elbow, and knee are particularly susceptible to the condition. Many risk factors for the development of arthrofibrosis cannot be controlled by the patient or surgeon. Early postoperative motion should be promoted whenever possible. Manipulations under anesthesia are effective for a period of time in certain fracture patterns, and open or arthroscopic surgical debridements should be reserved for the patient for whom nonoperative modalities fail and who has a clinically significant deficit.

Biomechanical performance of retrograde nail for supracondylar fractures stabilization. Med Biol Eng Comput 2016; 54:939-52.

Abstract
The study compared the biomechanical performance of retrograde nail used to stabilize supracondylar fracture (three different levels) by means of finite element analysis. Three different nail lengths (200, 260, and 300 mm) of stainless steel and titanium nails were under consideration. Intact femur model was reconstructed from Digital Imaging and Communications in Medicine images of Thai cadaveric femur scanned by computed tomography spiral scanner, whereas geometry of retrograde nail was reconstructed with the data obtained from three-dimensional laser scanner. The retrograde nail was virtually attached to the femur before nodes and elements were generated for finite element model. The finite element models were analyzed in two stages, the early stage of fracture healing and the stage after fracture healing. The finding indicated that purchasing proximal locking screw in the bowing region of the femur may be at risk due to the high stresses at the implant and bone. There were no differences in stress level, elastic strain at a fracture gap, and bone stress between stainless steel and titanium implant. Since the intramedullary canal requires reaming to accommodate the retrograde nail, the length of retrograde nail should be as long as necessary. However, in case that the retrograde nail can be accommodated into the intramedullary canal without reaming, the longer retrograde nail can be used.

Abstract
Background: Postoperative knee soft tissue irritation is a common complication after retrograde nail fixation of femoral fractures. Distal locking screw prominence is one of the causes for soft tissue irritation. This study aimed to determine whether the use of the femoral condyles tangential views improve the diagnostic accuracy compared with anteroposterior (A-P) view in detecting distal locking screw penetrations during retrograde femoral nailing. Methods: The angle between the sagittal plane and lateral aspect of the condyle and the angle between the sagittal plane and medial aspect of condyle were measured on computed tomography (CT) images. After the angles were measured and recorded, cadaveric femurs were used in a simulated surgical procedure. The retrograde femoral nail was inserted into the femur and placed distal locking screws, which were left 2, 4, and 6 mm proud of the medial and lateral condyles for each femur. A-P view, lateral condyle tangential view and medial condyle tangential view were obtained. All fluoroscopic images were recorded and sent to three observers blinded to the experimental procedure to determine whether screws penetrated the condyle cortex or not. Results: According to the results of CT scan, the lateral condyle view was 20.88 ± 0.98° and the medial condyle view was 40.46 ± 3.14°. In the A-P view, we detected 0% at 2 mm penetration, 16.7% (lateral condyle screw) and 25.0% (medial condyle screw) at 4 mm, and 41.7% (lateral condyle screw) and 58.3% (medial condyle screw) at 6 mm. In the lateral tangential view, we detected 91.7% at 2 mm penetration of the lateral condyle and 100% at 4 mm and 6 mm. In the medial tangential view, we detected 66.7% at 2 mm penetration of the medial condyle and 100% at 4 mm and 6 mm. The femoral condyle tangential views provided significant improvement in detecting screw penetrations at all lengths (2, 4, and 6 mm) compared with the A-P view (P < 0.05). Conclusions: The femoral condyles tangential views increased the accuracy of detecting screw penetrations on the medial and lateral condyles. Routine clinical use of the femoral condyles tangential views has the potential to increase accuracy in detecting distal locking screw penetration during retrograde femoral nailing.

Abstract
Fractures of the distal femur, even those with articular extension, are well suited to surgical fixation with modern precontoured anatomic plates and nails. Numerous adjuvant techniques are available to the treating surgeon to obtain and maintain reduction while preserving fracture biology. Yet despite their proven track record and benefits over older implants, technical errors are common and must be overcome with proper preoperative planning and intraoperative attention to detail. This review summarizes the current state of the art regarding distal femur fractures, with an emphasis on relevant modern plate and nail surgical techniques, tempered by our current understanding of implant biomechanics, fracture healing, and long-term outcomes.

Abstract
OBJECTIVE Treatment of distal femoral fracture in post-polio patients is difficult because the bone is usually osteopenic, small and deformed. This retrospective study aimed to investigate the outcomes of distal femoral fracture in post-polio patients treated by locking compression plates (LCP). METHODS The medical records of 19 post-polio patients (mean age 49 years at time of surgery) were reviewed and intraoperative data retrieved. Fracture union and callus formation were evaluated on radiographs taken at each postoperative visit. Functional outcome assessments included range of motion and Hospital for Special Surgery (HSS) score of the ipsilateral knee joint. RESULTS Sixteen femoral fractures occurred in the poliomyelitis-affected limbs. The mean duration of operation was 86 min and mean blood loss 120 mL. All fractures healed (mean, four months) but union was delayed in one. At the final follow-up 2 yrs after surgery, the mean range of knee flexion was 105° (range, 90°-130°), and mean HSS score 76 points (range, 60-93). There were no cases of nonunion, implant cutout, or other complications. CONCLUSIONS LCP provides stable fixation of distal femoral fractures in post-polio patients. Bony union and good functional outcomes are achieved, but delayed union and minimal callus may occur.

Abstract
BACKGROUND The incidence of distal femur fracture in the elderly has been increasing recently, and commonly occurs with osteoporosis. Retrograde intramedullary nailing has been considered a good surgical option for distal femur fracture. The purpose of the present study was to present our surgical results with retrograde intramedullary nailing for distal femur fractures with osteoporosis. METHODS Thirteen patients diagnosed with extra-articular distal femur fracture and osteoporosis and managed with retrograde intramedullary nailing were retrospectively reviewed. Cement augmentation was used in four patients, shape memory alloy was used in eight patients and both were used in one patient. All patients were followed up for more than 2 years. Radiologic alignments were scored and Tegner and the Lysholm activity score was used for a functional assessment. RESULTS The average time to clinical union was 13 weeks (range, 10 to 15 weeks). In 12 of our cases, the total alignment scores were excellent. At the last follow-up, the mean range of motion was 116° (range, 110° to 125°). The average functional score at postoperative 1 year was 2.6 (range, 1 to 5). CONCLUSIONS Retrograde intramedullary nailing is a good surgical option for distal femur fracture with osteoporosis. Cement augmentation and shape memory alloy can also be used for added mechanical stability. This surgical technique is very useful for distal femur fracture with osteoporosis as it promotes fracture healing and early rehabilitation.

Abstract
BACKGROUND Distal femur fractures continue to be a complex surgical problem for which the incidence is increasing. Presently, there is a need for different constructs to address these complex fractures. This study attempts to define the biomechanical properties of several implants. METHODS A novel, prototype locking retrograde intramedullary nail and the Russell-Taylor femoral retrograde nail were tested at non-destructive, physiological, axial mode load strength using a young, synthetic bone model for a medial segmental shaft defect in the supracondylar region of the distal femur (medial gap of 10mm, 65mm proximal to the distal joint and parallel to the knee axis). Each specimen was compressively loaded and unloaded to the peak load for 80,000cycles at a 0.5Hz frequency. These were compared to the results from the same lab of the retrograde Trigen intramedullary nail. Motion and peak displacement were measured across the fracture site as a reflection of construct stability. FINDINGS Previous testing demonstrated that Trigen intramedullary nail had significantly less motion across the gap and increased overall stiffness of the construct (P<0.05) compared to both Russell-Taylor and prototype nails. INTERPRETATION Locking technology used in a nail biomechanically appears to lead to more micro-motion across the fracture gap and to less stiffness in this construct. Further research needs to be invested into intramedullary, locking technology before introducing it into clinical practice.

Abstract
OBJECTIVES In the distal femur, locked plating is efficacious when coronal fractures preclude the use of a conventional fixed-angle device. However, minimal comparative data exist for supracondylar fracture patterns, which could be treated with other devices. The purpose of this study was to compare the 95-degree angled blade plate (ABP) versus the Locking Condylar Plate (LCP) by assessing complications and secondary procedures in fractures amenable to treatment with either implant. DESIGN Retrospective review. SETTING Level 1 trauma center. PATIENTS/PARTICIPANTS Seventy patients with 71 distal femoral fractures (OTA 33-A, 33-C1, 33-C2) amenable to either ABP or LCP with a mean age of 59.5 years (range, 20-92 years) were included. Seventeen fractures (24%) occurred adjacent to a previous knee arthroplasty (10 ABP and 7 LCP). The 2 groups were similar with respect to age, fracture pattern, and the presence of open fracture. Most injuries were the result of high-energy trauma, and 21% were open fractures. INTERVENTION Thirty-two fractures (45%) were treated with an ABP, and 39 (55%) were treated with the LCP. MAIN OUTCOME MEASURES Complications, including infection, nonunion, and malunion, and secondary operations were determined. RESULTS After a mean of 26-month follow-up, 4 patients (6.0%) were treated for infections. Malunions occurred in 11% of LCP patients and in 1 ABP patient (3.4%, P = 0.14). All patients with malunions were older than 55 years. Seven patients (11%) were treated for nonunions. Six of the nonunions occurred after LCP (16% vs. 3.4%, P = 0.11) Complications were more frequent in LCP patients (35%) versus ABP patients (10%, P = 0.001). Complications were not related to fracture pattern, periprosthetic fracture, or open fracture. Mean age of patients with complications was 64 years (vs. 53 years, P = 0.01), and they were more likely to have lower energy mechanisms (P = 0.017). Overall, 18 patients (27%) underwent secondary procedures, including treatment of infection, nonunion, malunion, or prominent implant removal. Secondary procedures were more common after LCP (43%) versus ABP (6.9%, P = 0.0008) patients. Painful prominent implants were removed from 7 LCP patients (18%) and no ABP patients (P = 0.01). CONCLUSIONS Distal femur fractures are often associated with prolonged healing and rehabilitation times, which increase substantially when complications occur. Internal fixation of these fractures may be performed successfully with ABP or LCP. In our review of fractures that could be treated with either implant, patients treated with locking plates had more complications and nonunions, requiring more secondary procedures to treat complications and to remove prominent implants. Furthermore, locking plates are substantially more expensive than conventional fixed-angle devices. Future investigation is needed in the form of a large randomized prospective study to clearly define clinical differences, functional outcomes, and costs of care. LEVEL OF EVIDENCE Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Abstract
Fractures of the distal femur still represent injuries that are difficult to treat as they either affect younger patients after a high-energy trauma with soft tissue damage and osseous comminution or elderly people with impaired local vascularity and a poor bone stock. However, exactly these fractures profit from new, biological principles of treatment, which help to diminish additional surgical trauma by indirect fracture reduction and insertion of stabilizing implants via mini-incisions. Basically, these techniques are represented by retrograde intramedullary nails and submuscularilly inserted plates/internal fixateurs. While intramedullary nails are well suited to fix extramedullary and simple articular fractures (C1), plates can also be used to treat complex articular fractures. Nevertheless, any displaced articular fracture component must still be anatomically reduced by an open approach and fixed with absolute stability. Technical advances as well as demographic changes will continue to represent challenges in the treatment of these fractures.

Abstract
Background One potential complication of retrograde femoral nailing in the treatment of femur fractures is the risk of septic knee. This risk theoretically increases in open fractures as a contaminated fracture site has the potential to seed the instrumentation being passed in and out of the sterile intraarticular starting point. There are few studies examining this potential complication in a relatively commonly practiced technique. Methods All patients who received a retrograde femoral nail for femur fracture between September 1996 and November 2006 at a Level 1 trauma center were retrospectively reviewed. This yielded 143 closed fractures, 38 open fractures and 4 closed fractures with an ipsilateral traumatic knee arthrotomy. Patient follow-up records were reviewed for documentation of septic knee via operative notes, wound culture or knee aspirate data, or the administration of antibiotics for suspected septic knee. Results No evidence of septic knee was found in the 185 fractures examined in the dataset. Utilizing the Wilson confidence interval, the rate of septic knee based on our population was no greater than 2%, with that of the open fracture group alone being 9%. Conclusions Based on these results and review of the literature, the risk of septic knee in retrograde femoral nailing of both open and closed femoral shaft fractures appears low but potentially not insignificant. Funding There was no outside source of funding from either industry or other organization for this study.

Abstract
BACKGROUND A distal femur nail with fixed-angle locking screws intends to combine the advantages of angular stability and intramedullary stabilization in extraarticular distal femur fractures. The goal of this study was to analyze whether the locked compression distal femur nail (LCN) was biomechanically more stable than a conventional standard distal femur nail (CN). METHODS Both nails were compared on a series of 10 matched pairs of human femora. After setting a distal femur defect fracture, the intramedullary stabilized femur was axially loaded starting from 100 N, increasing in steps of 100 N after every 200 cycles with a triangular frequency of 1 Hz, until a predefined point of failure was reached. RESULTS The two types of nails showed no significant difference in terms of maximum tolerated load, maximum number of cycles repeated, or axial deformation of the bone-implant construct. The mean load at failure was 2,954 N for the CN and 2,483 N for the LCN. The mean axial deformation for the conventional (14.8 mm) and locked compression nail (15.3 mm) did not differ significantly. Mode of failure was a bony fracture in all specimens predominantly involving the proximal femur. CONCLUSIONS No significant difference in stability between the two compared implants could be demonstrated. The LCN showed comparable characteristics under cyclic axial loading as the conventional distal femur nail. No migration into the articular space or implant failure was observed.

Abstract
Retrograde femoral nailing is a widely used treatment for fractures involving the distal third of the femur. Angular malunion of these fractures after retrograde intramedullary nailing is a known complication. We report our surgical technique and experience using blocking screws to aid in reduction and augment the stability of the fixation when using a retrograde intramedullary nail for distal femoral fractures.

Abstract
PURPOSE The purpose of this systematic review was to assess the literature evaluating the clinical and radiological outcomes following less invasive surgical stabilisation system (LISS) fixation of distal femoral fractures (AO 32/33). METHODS A review of EMBASE, Medline, CINAHL and AMED from their inception to November 2008, sources of grey literature and a pertinent hand search of specialist orthopaedic journals was undertaken. RESULTS Twenty-one studies assessing 663 patients with 694 fractures were reviewed. The findings suggest that the LISS system may be an appropriate fixation method for the management of distal femoral fractures. However, there remains a high incidence of loss of reduction (n=134; 19%), delayed or non-union (n=40; 6%) and implant failure (n=38; 5%). On analysis, such complications were largely confined to articles published before 2005, therefore during the infancy of the widespread clinical application of this trauma system. On critical appraisal, the evidence-base remains limited by recruiting small, under-powered sample sizes and poorly accounting for confounding variables such as osteoporosis, diabetes, multi-trauma and fracture classification. CONCLUSION Further study is required to assess the outcomes of LISS fixation in specific patient populations, and to compare the outcome of this fixation method to condylar plates and intrameduallary devices, to determine the optimal management strategy for this complex patient group.

Abstract
This study employed both mechanical testing and finite element analysis to compare the stiffness variations among different intramedullary nail constructs used in the treatment of distal femoral fractures. Compressive and torsional experiments were conducted on a transversely, as well as an obliquely fractured sawbone femur restored with the retrograde intramedullary nail. Corresponding finite element models were established to evaluate the stress distributions around screw holes. The results showed that a perifracture screw could increase stiffness by 40% for the obliquely fractured femur, but that it played an insignificant role in stiffness improvement for the transverse fracture groups. Moreover, compared to proximal-screw fixation, distal-screw fixation could improve construct stiffness by 20%. The absence of one of the two distal screws would increase the screw-hole stress by 70%. Therefore, the distal screw around the metaphyseal region has a more important stabilizing effect in the femur-nail construct than does the proximal screw. A twisting stress pattern occurs on the unused screw holes of the metaphyseal region and induces a higher risk for fatigue fracture. The locking screw at the fracture site would be most effective only if it passed through the fracture gap to integrate the separated femoral pieces.

Abstract
BACKGROUND A variety of devices have been used in the treatment of supracondylar femoral fractures. The condylar blade plate relies on the principles of open reduction, absolute stability and interfragmentary compression to achieve union. The technique of retrograde nailing uses indirect reduction of the metaphyseal fracture component, offering relative stability and a less invasive approach. Randomized comparison of these common methods of fixation has not been reported. METHODS Twenty-two patients with 23 supracondylar femur fractures were recruited from two regional trauma centres over a 26-month period and randomized to receive either a retrograde intramedullary nail fixation (IM group, 12 fractures) or a fixed-angle blade plate fixation (BP group, 11 fractures). The groups were followed for 12-36 months. The primary outcome measures were revision surgery and general health. RESULTS Three patients in the IM group required revision surgery for the removal of implant components. No reoperations occurred in the BP group. There was a trend towards greater pain in the IM group, although there was no statistically significant difference in the scores for any of the SF-36 domains. CONCLUSION Both distal femoral nailing and blade plating give good outcomes. There is a trend for patients undergoing retrograde nailing to complain of more pain and to require revision surgery for removal of implants.

Abstract
BACKGROUND Torsional malalignment and mechanical axis deviation (MAD) are worrisome complications after nailing of distal femoral fractures. Variable, sometimes contradictory, reports about these problems have been published. METHODS In a retrospective nonrandomized study, 41 patients (mean age, 44.5 years) with distal third femoral fractures that were operatively treated using either antegrade (20 cases) or retrograde (21 cases) intramedullary nailing during a period of 2 years have been reviewed. Goniometric measurement was done using a navigated ultrasound examination whereas functional evaluation and return to sports were assessed using Merle d'Aubigné functional grading system and Tegner and Lysholm activity score. RESULTS There was no difference in femoral length, torsion, or MAD between patients treated using antegrade nails and those treated with a retrograde nail. There was a greater limitation of knee motion with retrograde nailing and of hip motion with antegrade nailing. The functional grading and activity evaluation showed, however, no difference between both groups. CONCLUSIONS The study cohort showed that no treatment method had proved an advantage over the other regarding limb geometry or the functional outcome. The proper operative indication, intraoperative control, and the surgeon's experience seem to be more important in this regard than the nailing technique.

Abstract
BACKGROUND The incidence of distal femur fractures is approximately 37 per 100,000 person-years. Typically, distal femur fractures are caused by a high-energy injury mechanism in young men or a low-energy mechanism in elderly women. Managing these fractures can be a challenging task. Most surgeons agree that distal femur fractures need to be treated operatively to achieve optimal patient outcomes. The articular fracture component is usually treated with open reduction and internal lag screw fixation or external tension wire fixation (Illizarov). However, there is no consensus on the type of implant for the fixation of the metaphyseal-diaphyseal fracture component. OBJECTIVE The aim of this study is to systematically summarize and compare the results of different fixation techniques (traditional compression plating, antegrade nailing, retrograde nailing, submuscular locked internal fixation, and external fixation) in the operative management of acute nonperiprosthetic distal femur fractures (AO/OTA type 33A and C) and the characteristics of the fractures for each treatment (articular/nonarticular and open/closed). Additionally an attempt was made to evaluate the impact of surgical experience on nonunion rate, fixation failure rate, deep infection rate, and secondary surgical procedure rate. In the context of this article compression plating relates to techniques/implants that require compression of the implant to the femoral shaft-it does not relate to interfragmentary compression.

Abstract
The aim of this analysis has been to evaluate the efficacy of retrograde nailing in the treatment of distal femur and femoral shaft fractures. Articles were extracted from the Pubmed database and the retrieved reports were included in the study only if pre-specified eligibility criteria were fulfilled. Moreover, a constructed questionnaire was administered, aimed at assessing the quality of the outcomes. Twenty-four articles were eligible for the final analysis, reviewing a total of 914 patients (mean age of 48.8 years) who sustained 963 distal and diaphyseal femoral fractures. The overall mortality rate was 5.3%. The incidence of infection was 1.1% and for septic arthritis of the knee was 0.18%. In patients with distal femoral fractures, the mean time to union and rate to union were 3.4 months and 96.9%, respectively. The mean range of knee motion was 104.6 degrees . The rates of knee pain, malunion and re-operations were 16.5, 5.2 and 17%, respectively. Patients with femoral shaft fractures had a mean time to union 3.2 months, whilst the rate of union was 94.2%. The mean range of knee motion was 127.6 degrees . The rates of knee pain, malunion and re-operations were 24.5, 7.4 and 17.7%, respectively. We concluded that retrograde intramedullary nailing appears to be a reliable treatment option, mainly for distal femoral fractures. However, in the management of diaphyseal fractures, retrograde intramedullary nailing is associated with high rates of knee pain and lower rates of fracture union.
