Abstract
PURPOSE The distal femur comprises a wide intramedullary cavity and thin cortical bone. Firm internal fixation of comminuted fractures with displacement is challenging. Although many comparative studies have reported retrograde intramedullary nailing (RIN) and distal femoral plating (DFP) as the usual fixation methods for distal femoral fractures, no clear conclusion has been reached. Therefore, a meta-analysis and systematic review of the clinical and radiological results were conducted to determine the appropriate treatment method for distal femoral fractures. METHODS A systematic search of the PubMed, Embase, Scopus, and Cochrane Library databases from their inception to December 19, 2022, was performed using predefined criteria. Studies comparing the effects of RIN and DFP were considered. The analyzed outcome measures included duration of surgery, blood loss, time to union, delayed union, nonunion, malalignment, implant failure, infection, reoperation, limb length discrepancy, range of motion, persistent anterior knee pain, knee stiffness, and functional scores. Meta-analysis of pooled data was conducted using a random-effects model to determine the standard mean difference (SMD) or odds ratio (OR) with 95% confidence intervals (CIs). RESULTS Thirty-three studies with 2,432 patients were included. Compared to DFP, RIN was associated with a shorter time to fracture union (SMD, 1.83 months; 95% CI - 2.76 to - 0.90; P < 0.001) and a lower incidence of postoperative infection (OR 0.54; 95% CI 0.31-0.94; P = 0.03). Pooled analysis revealed no significant differences in other outcome measures between the two treatment modalities. CONCLUSION In distal femoral fractures, RIN had a shorter bone union time and was more resistant to infection than DFP. However, there were no significant differences in the other clinical parameters. Therefore, the characteristics, strengths, and weaknesses of RIN and DFP should be carefully identified, and appropriate treatment should be provided based on the patient's medical condition and fracture pattern.

Abstract
Purpose The fixation method of distal, extra-articular femur fractures is a controversially discussed. To ensure better stability itself, earlier mobilization and to prevent blood loss - all these are justifications for addressing the femur via reamed intramedullary nailing (RIMN). Anatomical reposition of multifragmentary fractures followed by increased risks of non-union are compelling reasons against it. The purpose of this study was to systematically review the literature for rates of non-union and wound infection, as well as blood loss and time of surgery. Methods According to the PRISMA guidelines we conducted this systematic review by searching the Cochrane, PubMed, Ovid, MedLine, and Embase databases. Inclusion criteria were the modified Coleman methodology score (mCMS) >60, age >18 years, and extra-articular fractures of the distal femur. Biomechanical and animal studies were excluded. By referring to title and abstract relevant articles were reviewed independently. In the consecutive meta-analysis, we compared 9 studies and 639 patients. Results There is no statistically significant difference comparing superficial wound infections when RIMN was performed (OR = 0.50; 95% CI: 0.18 - 1.42; P = 0.19) as well as in deep wound infections (OR = 0.74; 95% CI: 0.19-2.81; P = 0.62). However, these results were not significant. We also calculated for potential differences in the rate of non-unions depending on the surgical treatment applied. Data of 556 patients revealed an overall number of 43 non-unions. There was no significant difference in rate of non-unions between both groups (OR = 0.97; 95% CI: 0.51-1.85; P = 0.92). Conclusion No statistical difference was found in our study among RIMN and plate fixation in the treatment of distal femoral fractures with regard to the incidence of non-union and wound infections. Therefore, the indication for RIMN or plating should be made individually and based on the surgeon's experience.

Abstract
OBJECTIVE Intertrochanteric fracture of the femur is a common fracture in older people. Due to the poor systemic condition and prognosis of elderly patients, it is prone to more complications. We introduce the bone-setting concept in the design of the robots, which are used for intertrochanteric fracture of the femur reduction. The purpose of this study is to compare the effect of bone-setting robots and conventional reduction in the treatment of intertrochanteric fracture of the femur (IFF). METHODS From June 2021 to January 2023, 60 patients with IFF who were treated surgically were assigned to bone-setting robots group and conventional reduction methods group in this retrospective study. The reduction time, operation time, total time, intraoperative blood loss, incision length, fluoroscopy time, and the follow-up time were reviewed. The visual analogue scale (VAS) and Harris scores were used for functional assessment. For continuous variables, independent t-tests were applied; for categorical data, the chi-square test was applied. The significance level as p < 0.05. RESULTS Among the 60 patients with IFF, 31 were assigned to the bone-setting robots group, and 29 were assigned to the conventional reduction methods group. Both groups with a similar baseline in the number, gender, age, and classification (p > 0.05). The reduction time, operation time, total time, intraoperative blood loss, and fluoroscopy time were less than those in the bone-setting robots reduction group compared to the conventional reduction group. In the bone-setting robots reduction group, the preoperative VAS score was 6.2 ± 1.3, the Harris score was 35.3 ± 3.1, 1 week after surgery VAS score was 3.3 ± 1.2, the Harris score was 57.3 ± 3.7, and at the last follow-up VAS score was 2.4 ± 0.8, and the Harris score was 88.7 ± 3.4. While in the conventional reduction group, the preoperative VAS score was 6.3 ± 1.3, the Harris score was 35.9 ± 2.9, 1 week after surgery VAS score was 4.8 ± 1.4, the Harris score was 46.8 ± 2.8, and at the last follow-up VAS score was 2.6 ± 0.8, and the Harris score was 87.3 ± 3.3. There were no significant differences between the two groups at the preoperative and 6-month postoperative follow-ups in VAS score and Harris score (p > 0.05, p > 0.05, respectively). But the difference was statistically significant at the one-week postoperative follow-up in VAS and Harris scores (p < 0.001). CONCLUSION The bone-setting robots can better protect the "fracture environment" and have the advantages of being precise, minimally invasive, simple, short time, low radiation, and rapid fracture recovery. The clinical effect of closed repair of IFF is ideal.

Abstract
Distal femur fractures are a common problem in orthopedics. Intramedullary retrograde nails (IRN) and dynamic condylar screws (DCS) are generally used for the treatment of these fractures. In this study, it was aimed to mechanically evaluate and compare these two implants used for the treatment of distal femur fractures. In this study, an AOOTA 33C1.3 fracture was created on the intact femur obtained from computed tomography images. The fractures were fixed with DCS and IRN. Then the created models were imported into the ANSYS Workbench for finite element analysis to determine the most convenient mechanical fixation type. The distal region of the femur was loaded considering 75 kg-f, and the created models were constrained in all directions from the femoral head. The intact femur was also analyzed to compare it with the DCS and IRN fixation models. The von Mises stress, strain, and displacement results were examined to determine the damage risk. According to the results, the risk of damage is lower in the model of fixation with IRN. The normal strain distribution in the model fixed with IRN is closer to the model of an intact femur. For this reason, the risk of stress shielding in IRN fixation is less than in DCS fixation. However, the fracture lines were more stable in the fixation with the DCS. In conclusion, fracture fixation with IRN is mechanically more suitable for distal femur fractures in terms of fracture healing.

Abstract
Intramedullary nailing is a common orthopedic procedure, but current methods for distal screw locking have several limitations. This study introduces and evaluates a novel technique that aims to overcome these challenges. The findings were statistically significant, with P-values set at .05. Compared to the traditional method, the novel technique demonstrated several advantages. Mean operation times were reduced to 1.2 hours for the new method, in contrast to 1.5 hours for the control group. Hospital stays also favored the new technique, with a mean duration of 2 days, while the control group averaged 3 days. A significant benefit was the marked decrease in radiation exposure, with the new technique eliminating radiation entirely, recording 0.0 mSv compared to the control group's 2.5 mSv. The procedure's success, gauged by the accurate positioning of screws, was higher for the new technique at 92% versus the control's 78%. Furthermore, complication rates were notably lower in the new method, with a 6% incidence compared to 16% in the traditional approach. While the data suggest that the new technique holds promising advantages, such as reduced operation times, decreased radiation exposure, and fewer complications, it is essential to conduct more extensive research for comprehensive validation. Despite the optimistic results, the study acknowledges the need for larger-scale trials to solidify these findings.

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.

Comparison of outcomes of retrograde intramedullary nailing versus locking plate fixation in distal femur fractures: A Systematic Review and Meta-analysis of 936 patients in 16 studies. J Orthop 2023; 36:36-48. [PMID: 36591439 PMCID: PMC9800249 DOI: 10.1016/j.jor.2022.12.007] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/22/2022] [Revised: 12/04/2022] [Accepted: 12/12/2022] [Indexed: 12/23/2022] Open
Abstract
Background The surgical treatment for distal femur fractures has evolved over time, and it depends upon certain factors; open or closed fracture type, the pattern of fracture, presence of metaphyseal comminution, intra-articular extension, and the bone quality are some of the crucial ones. Both retrograde intramedullary nails (RIMN) and locking plates (LP) can be used for the fixation of these fractures. However, the optimal method among the two devices is still a topic of debate, the superiority of one over the other being unclear. Hence, this systematic review and meta-analysis was conceptualized to compare the outcomes of RIMN with distal femur LP. Methods The primary electronic search was conducted on Medline (PubMed), Scopus, Embase, Cinahl, and Cochrane Library databases for the published literature from the inception to 25th February 2022. The studies compared outcomes of RIMN versus LP fixation of the acute supracondylar or distal femur fracture (AO/OTA type-33A, B, and C) and reported at least one primary (mean fracture union time, complications, implant-related complications, and re-operation rate) or secondary outcome (duration of surgery, intra-operative blood loss, and knee range of motion), were included. Results Six randomized control trials, 2 prospective and 8 retrospective studies with 936 patients with 8 bilateral cases (467: RIMN; 477: LP) were included. Our analysis demonstrated no statistically significant difference in terms of mean fracture union time, overall complications, implant-related complications, re-operation rates, and duration of surgeries. Although a better knee range of motion was seen in the LP group, however, it also showed more nonunion and infection than the RIMN group. Conclusion The present review shows that there are significantly lesser nonunions and infections, in the RIMN group as compared to LP for distal femur fractures, although a better postoperative knee range of motion was seen in the latter. However, in terms of fracture union time, the overall rate of complications, re-operation rates, and duration of surgeries, there is no difference between the two surgical options.

Results of the surgical treatment of intra-articular fractures of the distal femur using a retrograde intramedullary technique. КЛИНИЧЕСКАЯ ПРАКТИКА 2023.

Abstract
Background: Distal femoral fractures are a widely spread problem in traumatology, which can be caused by both a high-energy trauma and a low-energy trauma in senile patients with osteoporosis. The conservative treatment shows little promise. The surgical treatment of patients is still a challenge for orthopedic surgeons regarding both the technical aspect and a high risk of complications. There are several surgical methods with the use of plates and nails, but there is still no universal conception of the surgical treatment.
Aim: comparative analysis of methods of intramedullary retrograde osteosynthesis and bone osteosynthesis in the treatment of fractures of the distal femur.
Methods: In this study, we evaluated the treatment results of 46 patients who underwent osteosynthesis for intraarticular fractures of the distal femur using an intramedullary retrograde nail. The evaluation was carried out based on such parameters as the duration of the operation and the time from the moment of injury to the operation, the intraoperative blood loss and the function of the knee joint. On average, the operation time using a retrograde femoral nail was 45 minutes. Reducing the duration of the operation improved the functional results of the treatment. Reducing the operation time when installing a retrograde intramedullary nail was achieved with a relatively simple technique for installing this type of a fixator and the use of minimally invasive approaches.
Results: On average, the operation time using a retrograde femoral nail was 45 minutes. Reducing the duration of the operation improved the functional results of treatment. Reducing the operation time when installing a retrograde intramedullary nail was due to a relatively simple technique for installing this type of fixator and the use of minimally invasive approaches. One year after the surgery, the following mean values were achieved: 78 (6485) points according to the KSS knee score, 85 (6889) points according to the KSS function score, 3.1 (1.34.2) cm for the severity of pain syndrome according to the VAS scale, 105 (88120) degrees for the flexion in the knee joint. However, a number of post-op complications were observed: deep vein thrombosis of lower extremities was found in 6 (13.1%) patients, formation of a false-joint was seen in 3 (6.5%) patients, 1st grade arthritis of the knee joint was detected in 36 patients (78.2%), 2nd grade arthritis was observed in 10 patients (21.8%). 3rd grade arthritis was not detected. 3.5 years after the operation, none of the patients needed a knee joint replacement.
Conclusion: Retrograde intramedullary osteosynthesis in type C distal femoral fractures promotes early rehabilitation, a complete recovery of the knee joint function and healing of the fracture, and represents an effective method of treatment.

Abstract
INTRODUCTION Pain and hemorrhage are common in midshaft femoral fractures. Traction splints (TSs) can reduce pain and control hemorrhage, but evidence of their effectiveness in femoral fractures is still lacking. Through a systematic review, we aimed to analyze and discuss the potential role of TSs in the prehospital and emergency department (ED) setting. METHODS The Embase, CINAHL, Cochrane, and PubMed databases were searched up to January 2022. All studies on femoral fractures in the prehospital or ED setting that compared TSs with immobilization or no intervention were included. Articles not written in English, German, or Dutch were excluded. Two authors screened all articles, assessed their quality, and included them if both agreed on their inclusion. The risk of bias was assessed using the modified Methodological Index for Non-Randomized Studies (MINORS). The primary outcome measures were pain and hemorrhage control, while the secondary outcome measures were survivability, morbidity, and complications. RESULTS A total of 1,248 articles matched the search strategy, 24 articles were assessed for eligibility based on their abstracts, resulting in 20 articles being included in the synthesis. Ten articles reviewed the effects of TSs on pain, while five reported that the use of a TS was appropriate. All five articles that reviewed blood loss found benefits from the use of a TS. One study found significantly fewer pulmonary complications in patients who were splinted earlier at the scene of injury (level III). No difference was found in complications or mortality between prehospital patients receiving a TS or no TS (level III). None of the studies noted that TSs were a necessity in the ED setting; however, some argued that a TS is a necessary and useful prehospital tool in rural or military areas. CONCLUSION TS use is associated with a decreased necessity for blood transfusions and fewer pulmonary complications. No favorable effects were found in terms of pain relief. We recommend the use of TSs in situations where one is likely to encounter a femoral fracture as well as when the time to definitive treatment is long. Further well-designed studies are required to validate these recommendations.

Abstract
PURPOSE To assess the outcome of surgically fixated femur shaft and distal femur fractures following low-velocity civilian gunshot injuries over a 4-year period. METHODS A retrospective review was conducted on all patients who sustained femur shaft and distal femur fractures from civilian low-velocity gunshot injuries that required definitive surgical fixation between January 2014 and December 2017. Patient demographics, comorbidities, injury characteristics, duration between injury and surgical fixation and presence of complications were captured. RESULTS A total of 122 patients (mean age, 29.1 ± 9.5 years) were included. Supracondylar femur fractures (AO 33) accounted for 49% of total injuries, followed by femoral shaft (AO 32) and intra-articular distal femur fractures (AO 33 B & C) with 40% and 11%, respectively. Intramedullary nail fixation was the choice of treatment for femur shaft fractures (49.98%) and supracondylar fractures (63%). Intra-articular injuries were predominantly treated with distal femoral locking plates (85%). Arterial and nerve injuries were the most commonly encountered associated injuries occurring in five patients (4.1%) each. Fracture-related infection was diagnosed in two patients (1.6%). No cases of non-union and compartment syndrome were recorded. CONCLUSION Femur shaft and supracondylar fractures fixated with intramedullary nails are associated with low complication rates and perfect union rates. Our study suggests that intra-articular distal femur fractures fixated with locking plates and cannulated screws have a high complication rate and poorer surgical outcomes. Non-union and compartment syndrome are rare complications of gunshot femur fractures fixated with either intramedullary nails or locking plates.

Abstract
Introduction The etiology of Klippel-Trenaunay syndrome (KTS) has a significant impact on the management of patient requiring surgical interventions. We report the strategies employed to address an infected non-union in a patient with KTS. Case Report The patient was transported to an initial treating hospital with femoral shaft fracture after experiencing a fall. The patient was diagnosed with KTS due to vascular malformations identified after severe intraoperative hemorrhaging. An open reduction and internal fixation was performed to stabilize the bone. Nine months after surgery, the patient was transferred to our hospital due to lack of healing with infected non-union. We prioritized treating the infection and plate displacement, and subsequently performed intramedullary nailing. Infection and intraoperative hemorrhaging were successfully controlled and bone union was confirmed 6 months after surgery. Conclusion The key factors to minimize procedural complications are sufficient preoperative evaluation and planning, surgical skill, and perioperative resource management.

Abstract
Interlocking of intramedullary nails is a challenging procedure in orthopedic trauma surgery. Numerous methods have been described to facilitate this process. But they are exposed patient and surgical team to X-rays or involves trial and error. An accurate and non-invasive method has been provided to easily interlocking intramedullary nails. By transferring a safe visible light inside the nail, a drilling position appears which use to drilling bone toward the nail hole. The wavelength of this light was obtained from ex-vivo spectroscopy on biological tissues which has optimal transmission, reflectance, and absorption properties. Moreover, animal and human experiments were performed to evaluate performance of the proposed system. Ex-vivo performance experiments were performed successfully on two groups of cow and sheep samples. Output parameters were procedure time and drilling quality which there were significant differences between the two groups in procedure time (P < 0.05). But no significant differences were observed in drilling quality (P > 0.05). Moreover, an In-vivo performance experiment was performed successfully on a middle-aged man. To compare the provided method, targeting-arm, and free-hand techniques, two human experiments were performed on a middle-aged and a young man. The results indicate the advantage of the proposed technique in the procedure time (P < 0.05), while the drilling quality is equal to the free-hand technique (P = 0.05). Intramedullary nail holes laser indicator is a safe and accurate method that reduced surgical time and simplifies the process. This new technology makes it easier to interlocking the intramedullary nail which can have good clinical applications.
