[PMID: 38804115 DOI: 10.1002/jor.25908] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/10/2023] [Revised: 04/07/2024] [Accepted: 05/08/2024] [Indexed: 05/29/2024]
Abstract
The purpose of this study was to assess the biomechanical contributions of the nail and the plate individually to a complete nail-plate construct in the setting of comminuted distal femur fractures. For this biomechanical study, comminuted extra-articular distal femur fractures were created in 24 synthetic osteoporotic femur models. These were then split into three groups: the nail-only group, the plate-only group, and the nail-plate group. After fixation, each specimen underwent sequential axial and torsional loading, and axial and torsional stiffness were calculated and compared. The addition of a nail to a plate-only construct increased axial stiffness by 19.7% and torsional stiffness by 59.4%. The plate-only group and nail-plate group both demonstrated significantly greater axial and torsional stiffness than the nail-only group at all levels of axial and torsional load. (p < 0.001) At 1000 and 2000 N of cyclic loading, the nail-plate group demonstrated significantly greater axial stiffness than the plate-only group (p ≤ 0.018). The nail-plate group demonstrated greater torsional stiffness than the plate-only groups at all levels of torsional loading (p < 0.001). In osteoporotic comminuted distal femur fracture models, most of the axial stiffness in a nail-plate construct comes from the plate. While the combination of the two constructs is not fully additive, the plate contributes the majority of the axial and torsional stiffness in a nail-plate construct. The supplementation of the plate with a nail primarily helps to increase resistance to rotational forces. Level of Evidence: III.

Abstract
BACKGROUND Demographics of patients who sustain geriatric distal femoral fractures (DFF) match those of patients with neck-of-femur fractures but have limited evidence with which to support post-operative weightbearing protocols. PURPOSE This systematic review sought to identify any difference in outcomes for elderly patients with DFF who were allowed early versus delayed weightbearing postoperatively. METHODS DATA SOURCES: PubMed, Medline, Embase and The Cochrane Library, reference lists of retrieved articles. STUDY SELECTION English language papers published between January 2010 and February 2023 with AO-OTA type 33A, B and C femoral fractures as well as Lewis and Rorabeck Type I and II periprosthetic DFF surgically treated with either a lateral locking plate or retrograde intramedullary nail and an average patient age of ≥ 60 years. DATA EXTRACTION Studies were assessed for inclusion by two authors and quality was assessed using the MINORS tool. DATA SYNTHESIS Sixteen studies were included, Meta-analysis of non-union, malunion, infection, delayed union and implant complications was performed using Microsoft Excel and the MetaXL extension. The data on return to mobility were presented in narrative form. The analyses demonstrated no difference between the early and delayed weightbearing groups. CONCLUSIONS There are no significant differences in complication rates between early versus delayed weightbearing after surgery for DFF in an elderly population. The study results are limited by high heterogeneity and low-quality studies. High quality, prospective studies are needed to determine the ideal postoperative weightbearing protocol.

Total femoral spanning for distal femur "fragility" fractures utilising nail-plate fixation "short-term experience of a district general hospital". EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY & TRAUMATOLOGY : ORTHOPEDIE TRAUMATOLOGIE 2024; 34:2003-2013.

Abstract
PURPOSE Our primary objective was to investigate the time to radiological union following linked nail-plate fixation of distal femur "fragility" fractures. Secondary objectives were to evaluate all-cause reoperations, 90-day mortality, rate of blood transfusion and the impact on quality of life. METHODS In this retrospective study of all adults (≥ 65 years) with native or periprosthetic distal femur fragility fractures, underwent a linked nail-plate fixation, data were retrieved on fracture classifications, clinical frailty score, blood transfusion, length of hospital stay, 90-day mortality, time to radiological union, overall complication rates and EuroQoL-5D. RESULTS In total, 18 out of 23 patients completed sequential follow-up. Radiological union was observed in 14 patients (median 143 days; range 42-414). Three patients underwent reoperations. There were no implant failures or a subsequent periprosthetic fractures. Ninety-day mortality was 17.4%. Eighteen patients required blood transfusion. The QoL was significantly lower after index surgery (0.875 vs. 0.684; p < 0.01). CONCLUSION Based on our observation, with short-term follow-up, the linked nail-plate yields optimal stability to allow immediate weight bearing, in a cohort with moderate frailty. It is reproducible, with variable radiological union rates. The concept of "total femoral spanning" reduces the risk of subsequent periprosthetic fractures. The additional intervention has increased the rates of allogenic blood transfusion. There is significant impact on overall QoL, with almost 50% being more dependent in self-care.

Retrograde intramedullary nailing with supplemental plate and lag screws allows early weight bearing following distal end-segment femur fractures (AO/OTA 33) in a low-resource setting.

Abstract
PURPOSE To underline the feasibility of achieving early weight bearing in patients with distal end-segment femur fractures (AO/OTA 33) treated with retrograde intramedullary nailing and supplemental plate or lag screws in the absence of C-arm. METHODS 41 distal end-segment femur fractures (DFFs) included in the study were treated with SIGN nails with or without a side plate in a center that lacked intraoperative fluoroscopy and fracture table. A medial or lateral para-patellar incision was used for fracture reduction, nail insertion and side plate placement. Follow-ups were done at six weeks, 12 weeks, and six months post-operatively. RESULTS Distal end-segment fractures constituted 13.2% of all femur fractures treated. The patients' mean age and range were 49.6 and 23-83 years respectively. They were mostly injured in road traffic accidents. 27 were daily-income earners. By the 12th week post-operatively, 82.1% of them could flex their knee beyond 90°, all of them could bear weight fully, and 71.8% could squat & smile. CONCLUSION The study highlighted the procedure for retrograde nailing of DFFs in a setting without the requisite facilities for minimally-invasive surgeries. The findings demonstrated the feasibility of achieving an expedited weight bearing for the predominantly daily-income-earning victims to ensure early return to work and poverty reduction. While the small sample size is a limitation, the study does provide information that could serve as a basis for future randomized controlled trials in low-resource settings.

Abstract
INTRODUCTION The selection of the most optimal fixation method for fractures of the distal femur, whether intramedullary nail (NL), lateral locking plate (PL), or nail/plate (NP) is not always clear. This study retrospectively evaluates surgical patients with distal femur fractures and introduces a pilot study using cluster analysis to identify the most optimal fracture fixation method for a given fracture type. METHODS This is a retrospective cohort study of patients 18 years and older with an isolated distal femur fracture who presented to our Level-1 trauma center between January 1, 2012, and December 31, 2022, and obtained NL, PL, or NP implants. Patients with polytrauma and those without at least six months of follow-up were excluded. A chart review was used to obtain demographics, fracture classification, fixation method, and postoperative complications. A cluster analysis was performed. The following factors were used to determine a successful outcome: ambulatory status pre-injury and 6-12 months postoperatively, infection, non-union, mortality, and implant failure. RESULTS A total of 169 patients met inclusion criteria. No statistically significant association between the fracture classification and fixation type with overall outcome was found. However, patients treated with an NP (n = 14) had a success rate of 92.9% vs only a 68.1% success rate in those treated with a PL (n = 116) (p = 0.106). The most notable findings in the cluster analysis (15 total clusters) included transverse extraarticular fractures demonstrating 100% success if treated with NP (n = 6), 50% success with NL (n=2), and 78.57% success with PL fixation (n=14). NP constructs in complete articular fractures demonstrated success in 100% of patients (n = 5), whereas 77.78% of patients treated with NL (n = 9) and 61.36% of those treated with PL (n = 44). CONCLUSIONS Plate fixation was the predominant fixation method used for distal third femur fractures regardless of fracture classification. However, NP constructs trended towards improved success rates, especially in complete intraarticular and transverse extraarticular fractures, suggesting the potential benefit of additional fixation with these fractures. Cluster analysis provided a heuristic way of creating patient profiles in patients with distal third femur fractures. However, a larger cohort study is needed to corroborate these findings to ultimately develop a clinical decision-making tool that also accounts for patient specific characteristics.

Abstract
PURPOSE Distal femoral fractures account for 4-6% of fragility fractures. These may be managed using a combined nail-plate construct (NPC). The use of NPCs is gaining traction. Whilst several theoretical advantages exist, there is little evidence reporting on binary or patient-reported outcomes. The aim of the current study was to perform a systematic review of the available literature pertaining to NPCs and their treatment of native distal femoral fractures, appraising the outcomes and focusing on the rationale for their increasing uptake in recent literature. METHODS A comprehensive search of MEDLINE, EMBASE, Clinical Key, PubMed and Cochrane library was performed from date of inception up to in August 9, 2022. All study languages were included initially. A further Google Scholar search review was performed to identify any other studies not identified in the database interrogation. Studies were eligible if they reported on the use of nail-plate constructs in managing distal femoral fractures. Any outcome metric was permitted. The study was conducted in accordance with PRISMA guidelines. Risk of bias was assessed using the Methodological Index for non-randomised Studies tool. Quantitative analysis was performed using a log odds ratio random effects model. The Knapp-Hartung adjustment was utilised if the total number of included studies was < 5. Study effect sizes and appropriate plots were constructed to illustrate the outcomes data. RESULTS A total of four studies were eligible for inclusion. Study data was extracted and summarised with their relevant outcomes presented. The literature review demonstrated that the use of NPCs led to significantly earlier full weight bearing (p < 0.001) and had reduced non-union rates over a single construct, without affecting infection rates (12.5% vs. 5.6%; p = 0.289) and significantly lower implant failure rates (10.5% vs. 0%; p = 0.011). A meta-analysis is performed of available studies and Forrest plots presented. CONCLUSION The use of NPC in the management of native osteoporotic DFFs is gaining traction but the available evidence is of low grade with significant heterogeneity in small cohorts of patients. We suggest that a large-scale, multicentre prospective study should be performed, with agreed functional and radiological outcome metrics, to provide a more robust evidence base.

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
OBJECTIVES Distal femoral fractures are a significant injury sustained by low- and high-energy trauma. Common treatment practices are lateral locking plate or intramedullary nail fixation, with disadvantages including risk of non and malunion and limited post-operative weightbearing status. Combining both techniques as a nail-plate construct (NPC) theoretically achieves enhanced fixation to allow immediate weightbearing. The aim of this study is to examine radiographic union, malunion and patient-reported outcomes in distal femur NPC fixation. METHODS Single-center retrospective study including all patients >18 years who sustained distal femur fractures treated with NPC. Primary outcomes were radiographic union, malunion and patient reported outcome measures at minimum 1-year follow-up. Secondary outcome measures included post-operative mobility, length of stay and complications. Relevant variables of normality are reported as mean with standard deviation. Subgroup analysis of patients aged <65 and ≥65 years are provided. RESULTS Sixteen patients were included in the study. Rate of radiographic union was 100%. There was no case of malunion. All patients were allowed to bear full weight immediately post-operatively. Mean length of stay was 9.50 days, with 37.5% of patients discharged directly home. The majority (85.7%) of patients returned to pre-injury mobility. Early post-operative complications occurred in three patients. Three patients returned to theater. The mean EQ-5D-5L index value was 0.713, with 71.4% describing no problems with self-care and 85.7% reporting no or slight problems with usual daily activities. CONCLUSION The NPC provided stable fixation permitting full weightbearing post-operatively with no cases of non or malunion. Return to pre-injury mobility and activity are encouraging. Based on these results we support the use of nail-plate construct fixation in the management of distal femur fractures.

Abstract
PURPOSE OF REVIEW The purpose of this review paper is to summarize current weight-bearing guidelines for common geriatric fractures, around weight-bearing joints, of the upper and lower extremities. RECENT FINDINGS There is an increasing amount of literature investigating the safety and efficacy of early weight-bearing in geriatric fractures, particularly of the lower extremity. Many recent studies, although limited, suggest that early weight-bearing may be safe for geriatric distal femur and ankle fractures. Given the limited data pertaining to early weight-bearing in geriatric fractures, it is difficult to establish concrete weight-bearing guidelines in this population. However, in the literature available, early weight-bearing appears to be safe and effective across most injuries. The degree and time to weight-bearing vary significantly based on fracture type and treatment method. Future studies investigating postoperative weight-bearing protocols should focus on the growing geriatric population and identify methods to address specific barriers to early weight-bearing in these patients such as cognitive impairment, dependence on caregivers, and variations in post-acute disposition.

Abstract
OBJECTIVES To (1) report on clinical, radiographic, and functional outcomes after nail-plate fixation (NPF) of distal femur fractures and (2) compare outcomes after NPF with a propensity matched cohort of fractures treated with single precontoured lateral locking plates. DESIGN Multicenter retrospective cohort study. SETTING Ten Level 1 trauma centers. PATIENTS/PARTICIPANTS Patients with OTA/AO 33A or 33C fractures. INTERVENTION Fixation with (1) retrograde intramedullary nail combined with lateral locking plate (n = 33) or (2) single precontoured lateral locking plate alone (n = 867). MAIN OUTCOME MEASUREMENTS The main outcomes of interest were all-cause unplanned reoperation and presence of varus collapse at final follow-up. RESULTS One nail-plate patient underwent unplanned reoperation excluding infection and 2 underwent reoperation for infection at an average of 57 weeks after surgery. No nail-plate patients required unplanned reoperation to promote union and none exhibited varus collapse. More than 90% were ambulatory with no or minimal pain at final follow-up. In comparison, 7 of the 30 matched lateral locked plating patients underwent all-cause unplanned reoperation excluding infection (23% vs. 3%, P = 0.023), and an additional 3 lateral locked plating patients were found to have varus collapse on final radiographs (10% vs. 0%, P = 0.069). CONCLUSIONS Despite a high proportion of high-energy, open, and comminuted fractures, no NPF patients underwent unplanned reoperation to promote union or demonstrated varus collapse. Propensity score matched analysis revealed significantly lower rates of nonunion for NPF compared with lateral locked plating alone. Larger studies are needed to identify which distal femur fracture patients would most benefit from NPF. LEVEL OF EVIDENCE Therapeutic Level III.

Abstract
OBJECTIVES To determine the effect of linking the intramedullary nail and the laterally applied locking plate to treat comminuted distal femur fractures and allow for immediate weight bearing. METHODS Comminuted extra-articular distal femur fractures were created in 16 synthetic osteoporotic femurs and split into 2 groups: linked versus unlinked. In the linked construct, in addition to standard plate fixation and proximal locking of the nail, 2 nonthreaded locking bolts (prototypes) were placed through both the plate and the nail. In the unlinked construct, the same number of screws affixed the plate to the bone but were directed around the nail, and separate distal interlocking screws were placed for nail fixation. Each specimen underwent sequential axial and torsional loading, and axial and torsional stiffness were calculated and compared. RESULTS On average, the unlinked constructs demonstrated a greater axial stiffness at all levels of axial loading, and linked constructs demonstrated greater average rotational stiffness. However, there were no statistically significant differences ( P > 0.189) between the linked and unlinked groups at any axial or torsional load. CONCLUSION In distal femur fractures with metaphyseal comminution, there were no significant differences in axial or torsional stiffness when linking the plate to the nail. Linking the construct seems to provide no significant mechanical advantage compared with the unlinked environment, but it may be a useful strategy to reduce nail "traffic" in the distal segment with no significant disadvantage.

Abstract
Background and objective A non-union distal femur fracture is a challenging fracture to treat. Common treatment modalities for non-union distal femur fractures include dual plating, intramedullary nails, ilizarov, and hybrid fixators. Despite the availability of a wide armamentarium of constructs, the clinical and functional outcome of these modalities is often complicated by significant morbidity, joint stiffness, and delayed union. The augmentation of the intramedullary nail with a locking plate results in a robust architecture, improving the likelihood of union. The use of this nail plate construct improves biomechanical stability and restores limb alignment, which enables early rehabilitation and weight bearing and lowers the likelihood of fixation failure. Methodology A prospective study was conducted at the Government Institute of Medical Science, Greater Noida, from January 2021 to January 2022 on 10 patients with non-union of the distal femur. All the patients were operated on with nail plate construct. The minimum follow-up period was 12 months. Results A total of 10 patients with a mean age of 55 years were included. Six were earlier treated with an intramedullary nail and four with extramedullary implants. All patients were managed with implant removal and fixation with nail plate construct and bone grafting. The average duration of the union was 10.3 months. The International Knee Documentation Committee (IKDC) score improved from 30.6 preoperatively to 67.3 postoperatively. Only one patient developed a superficial infection, which was managed by wound debridement and targeted antibiotic therapy. Conclusion In our experience, this relatively novel technique of combining nail plate constructs offers encouraging outcomes in the management of non-union of distal femur fractures, especially in elderly and osteopenic patients.

Abstract
Distal femoral fractures in elderly or osteoporotic patients constitute a challenging injury, especially in the settings of fracture comminution or periprosthetic fractures. A recent trend in the treatment of these difficult injuries is the double fixation with a nail and a plate, a strategy that comes with advantages including faster weight-bearing and lower risk for non-union. Although biomechanical studies have demonstrated the superiority of nail-plate constructs, there is a paucity in the literature regarding the indications and results of treatment. A review of the literature to date was carried out to identify which group of patients would benefit the most from this type of reconstruction and to evaluate the clinical outcomes.

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
BACKGROUND Periprosthetic supracondylar femoral fractures (PSFs) present a challenge in terms of optimizing fixation in patients with poor bone quality. Surgical treatment and peri-operative management of PSFs in the elderly remain a burden for orthopedic surgeons. Among different treatment options, locking plate (LP) and retrograde intramedullary nail (RIMN) have shown favorable results. However, reduced mobility and protected weight-bearing are often present in the postoperative older population. With a purpose of allowing for early weight-bearing, a modified nail plate combination (NPC) was redesigned for PSF management.
CASE SUMMARY In our cases, two elderly osteoporotic female underwent total knee arthroplasty (TKA), and then suffered from low energy trauma onto their knees after falling to the floor. Plain radiographs or computed tomography scans demonstrated oblique or transverse PSFs, both of which occurred at the distal femur above TKA. The modified NPC technique was performed for treatment of PSFs. The patient was made foot flat weight bearing in 1 wk. At 6-mo follow-up, the union was ultimately achieved using modified NPC with satisfactory implant outcomes.
CONCLUSION Neither LP nor RIMN alone may provide adequate support to allow for union in circumstances where the patient has severely osteopenic bone. Therefore, developing a modified implant offer an alternative choice for treating PSFs. These two cases revealed that this technique is a viable option for the geriatric osteoporotic PSFs, offering safe, early weight bearing and favorable clinical outcomes.
