Abstract
INTRODUCTION The literature lacks a large-scale study investigating the effect of surgical fixation timing on early mortality and morbidity outcomes in distal femur fractures. The aims of this study were to determine the effect of fixation timing on in-hospital mortality and morbidity outcomes for operatively treated distal femur fractures retrospectively using large database data. METHODS This study is a retrospective analysis using data from the National Trauma Data Bank. Patients were stratified into a fragility cohort (age ≥ 60, ISS < 16) and polytrauma cohort (age < 60, ISS ≥16), with both cohorts analyzed separately. Within each cohort, patients were split into three fixation timing groups: within 24 h, between 24 and 48 h, and greater than 48 h from presentation to the hospital. Fixation-timing groups were compared based on the primary outcome of in-hospital mortality rate. Secondary outcomes included hospital length of stay (LOS), ICU length of stay (ICU LOS), days on a ventilator, and complications. RESULTS The fragility and polytrauma cohorts included 22,045 and 5,905 patients, respectively. The in-hospital mortality rate was 1.23 % in the fragility cohort and 2.56 % in the polytrauma cohort. Multivariate analysis of the fragility cohort showed that fixation greater than 48 h from time of presentation was associated with increased mortality compared to fixation within 24 h (OR 1.89, CI: 1.26-2.83, p=0.002) and between 24 and 48 h (OR 1.63, CI: 1.23-2.15, p<0.001). In the polytrauma cohort, multivariate analysis showed no significant mortality differences between fixation timing groups. Multivariate analysis of morbidity outcomes in both cohorts showed that fixation greater than 48 h was associated with increased LOS, ICU LOS, ventilator days, and complications compared to fixation within 24 h. In the polytrauma cohort, fixation between 24 and 48 h was associated with decreased LOS, ICU LOS, and complications compared to the other two timing groups. CONCLUSIONS Fixation of distal femur fractures before 48 h from presentation may lead to improved mortality and morbidity in older, lower injury severity patients. No significant mortality benefit was observed in younger, polytrauma fractures. Further prospective work is needed to validate these findings.

Abstract
INTRODUCTION Fractures of the distal femoral third are an important cause of morbidity and mortality, and their treatment is currently controversial. OBJECTIVES To compare the results between minimally invasive techniques versus exposure of the fracture site. Secondly, to evaluate the relationship between demographic factors, mechanism of injury and surgical delay with patient prognosis. METHOD Retrospective cohort study carried out between 2015 and 2021 in a tertiary hospital. Data collection was performed by reviewing medical histories, measuring demographic and hospital parameters and definitive treatment strategy. One year of follow-up was completed in all patients, assessing the occurrence of surgical complications and mortality. A stratified analysis of the variables of interest was performed among patients over 65 years of age. RESULTS 128 fractures were recorded, with definitive osteosynthesis being performed in 117. Patients who underwent minimally invasive techniques required a shorter hospital stay (9 [7-12] vs. 12 [8.75-16] days) (p=0.007), with no differences in mortality or complications during follow-up. In those over 65 years of age, opening the fracture site was associated with an increased risk of infection compared to minimally invasive techniques (33.3% vs. 2%) (p=0.507). All the deceased were patients over 65 years of age (33.7% at one year). Surgical delay longer than 48hours increased mortality by 10% among those older than 65 years (p=0.3). High-energy trauma had a higher proportion of pseudarthrosis (27.6% vs. 6.1%) (p=0.011). CONCLUSIONS Minimally invasive techniques decreased hospital stay but not complications or long-term mortality. LEVEL OF EVIDENCE IIb.

Abstract
OBJECTIVES To assess the biomechanical differences between linked and unlinked constructs in young and osteoporotic cadavers in addition to osteoporotic sawbones. METHODS Intraarticular distal femur fractures with comminuted metaphyseal regions were created in three young matched pair cadavers, three osteoporotic matched pair cadavers, and six osteoporotic sawbones. Precontoured distal femur locking plates were placed in addition to a standardized retrograde nail, with unitized constructs having one 4.5 mm locking screw placed distally through the nail. Nonunitized constructs had seven 4.5 mm locking screws placed through the plate around the nail, with one 5 mm distal interlock placed through the nail alone. Cadaveric specimens were subjected to axial fatigue loads between 150 and 1500 N (R Ratio = 10) with 1 Hx frequency for 10,000 cycles. Sawbones were axially loaded at 50% of the ultimate load for fatigue testing to achieve runout, with testing performed with 30 and 300 N (R Ratio = 10) loads with 1 Hz frequency for 10,000 cycles. RESULTS In young cadavers, there was no difference in the mean cyclic displacement of the unitized constructs (1.51 ± 0.62mm) compared to the non-unitized constructs (1.34 ± 0.47mm) (Figure 4A), (p = 0.722). In osteoporotic cadavers, there was no difference in the mean cyclic displacement of the unitized constructs (2.46 ± 0.47mm) compared to the non-unitized constructs (2.91 ± 1.49mm) (p =0.639). There was statistically no significant difference in cyclic displacement between the unitized and non-unitized groups in osteoporotic sawbones(p = 0.181). CONCLUSIONS Linked constructs did not demonstrate increased axial stiffness or decreased cyclical displacement in comparison to unlinked constructs in young cadaveric specimens, osteoporotic cadaveric specimens, or osteoporotic sawbones.

Abstract
OBJECTIVE Distal femur fractures remain a significant cause of morbidity and mortality for elderly patients. There is a lack of large population studies investigating short-term outcomes after distal femur c in elderly patients. The purpose of this study is to assess the incidence of and risk factors for various short-term outcomes after distal femur open reduction internal fixation (ORIF) in the geriatric population. METHODS The American College of Surgeons' National Surgical Quality Improvement Program (NSQIP) database was used to identify all primary distal femur ORIF cases in patients 60+ years old between January 1, 2015 and December 31, 2020 using Current Procedural Terminology (CPT) codes 27511, 27513, and 27514. Demographic, medical, and surgical variables were extracted for all patients. Propensity score matching was used to match cases in the two age groups based on various demographic and medical comorbidity variables. Several 30-day outcome measures were compared between the 60-79-year-old and 80+-year-old groups both before and after matching. Subsequent multivariate logistic regression was used to identify independent risk factors for 30-day outcome measures in the matched cohort. RESULTS A total of 2913 patients were included in the final cohort: 1711 patients in the 60-79-year-old group and 1202 patients in the 80+-year-old group. Most patients were female (n = 2385; 81.9%). Prior to matching, the older group had a higher incidence of 30-day mortality (1.9% vs. 6.2%), readmission (3.7% vs. 9.7%, p = 0.024), and non-home discharge (74.3% vs. 89.5%, p < 0.001). Additionally, the older group had a higher rate of blood loss requiring transfusion (30.9% vs. 42.3%, p < 0.001) and medical complications (10.4% vs. 16.4%, p < 0.001), including myocardial infarction (0.7% vs. 2.7%, p < 0.001), pneumonia (2.7% vs. 4.6%, p = 0.008), and urinary tract infection (4.1% vs. 6.1%, p = 0.0188). After matching, the older group consistently had a higher incidence of mortality, non-home-discharge, blood loss requiring transfusion, and myocardial infarction. Various independent risk factors were identified for 30-day morbidity and mortality, including American Society of Anesthesiologists (ASA) classification, body mass index (BMI) status, operative duration, and certain medical comorbidities. CONCLUSION Geriatric patients undergoing distal femur ORIF are at significant risk for 30-day morbidity and mortality. After matching, octogenarians and older patients specifically are at increased risk for mortality, non-home discharge, and surgical complications compared to patients aged 60-79 years old. Multiple factors, such as BMI status, ASA classification, operative time, and certain medical comorbidities, are independently associated with poor 30-day outcomes.

Abstract
PURPOSE This cohort study aimed to describe the functional outcomes, complications, and mortality of patients over 65 with acute distal femur fractures treated with open reduction and internal fixation (ORIF) or distal femoral replacement (DFR). METHODS We retrospectively analyzed all patients older than 65, operated consecutively for a distal femur fracture treated with ORIF or DFR. We included 75 patients (9 33A, 5 33B, and 61 33C AO/OTA fractures), 55 treated with ORIF, and 20 with DFR. We used Parker's mobility index (PMI) to assess functional outcomes at 1, 3, and 12 months and study closure. We analyzed complications, reoperations, and mortality at 30 days, one year, and at the end of the study. RESULTS The PMI was significantly higher in the DFR group at months 1 (p = 0.023) and 3 (p = 0.032). We found no significant differences between cohorts at one year and the end of follow-up. Postoperative complications were significantly more frequent in the ORIF group (38.10% vs. 10%, p = 0.022). Reoperations were similar in both cohorts (p = 0.98). Mortality at one month was 4% and 20% at one year, and at the end of follow-up, there were no significant differences between groups. CONCLUSION The outcomes of this study suggest that DFR offers a faster functional recovery with lower complication rates than those treated with ORIF. Additionally, both options have similar reoperation and mortality rates. Appropriately designed studies are needed to define the best treatment strategy for this type of patient.

Abstract
Objective Through meta-analysis, this study aims to comprehensively evaluate the efficacy of single-plating and double-plating in the treatment of comminuted fractures of the distal femur. Methods Computer searches of PubMed, Cochrane Library, Embase, China National Knowledge Infrastructure (CNKI), China Biology Medicine (CBM), VIP, and Wanfang digital journals were performed, and the timeframe for the searches was from the establishment of each database to July 2023 for each of the databases. Meta-analysis was performed using RevMan 5.4 software provided by the Cochrane Library, and the review process was registered in the PROSPERO database. Results A total of ten studies were included for statistical analysis. One randomised controlled study and nine retrospective cohort studies with a total of 563 patients were included. The double-plate group was superior to the single-plate group in terms of knee mobility at 6 months postoperatively, overall postoperative complications, and the rate of healing of knee deformity. However, it increased the operation time and intraoperative bleeding, and the difference between the two groups was statistically significant (P < 0.05). There was no significant difference between the two groups in terms of excellent knee function rate, fracture healing time, plate fracture, postoperative infection, delayed fracture healing, and non-union (P ≥ 0.05). Conclusion Double plate fixation for comminuted fractures of the distal femur can improve knee mobility at 6 months postoperatively, reduce overall postoperative complications, and decrease the incidence of malunion healing. However, it increases operative time and bleeding. Randomised studies are needed to provide strong evidence in the future.

Abstract
Distal femur fractures (DFFs) are common injuries with significant morbidity. Surgical options include open reduction and internal fixation (ORIF) with plates and/or intramedullary devices or a distal femur endoprosthesis (distal femur replacement [DFR]). A paucity of studies exist that compare the two modalities. The present study utilized a 1:2 propensity score match to compare 30-day outcomes of geriatric patients with DFFs who underwent an ORIF or DFR. The National Surgical Quality Improvement Program data from 2008 to 2019 were utilized to identify all patients who sustained a DFF and underwent either ORIF or DFR. This yielded 3,197 patients who underwent an ORIF versus 121 patients who underwent a DFR. A final sample of 363 patients (242 patients with ORIF vs. 121 with DFR) was obtained after a 1:2 propensity score match. Costs were obtained from the National Inpatient Sample database using multiple regression analysis and validated with a 7:3 train-test algorithm. Independent samples t-tests and chi-square analysis were conducted to assess cost and outcome differences, respectively. Patients who received a DFR had higher transfusion rates than ORIF (p = 0.021) and higher mean inpatient hospital costs (p = 0.001). Subgroup analysis for patients 80 years of age or older revealed higher 30-day unplanned readmission (0 vs. 18.2%; p < 0.001) and 30-day mortality (0 vs. 18.2%; p < 0.001) rates for patients undergoing ORIF compared with DFR. The total number of DFR cases needed to prevent one ORIF-related 30-day mortality for DFR for patients 80 years of age was 6 (95% confidence interval: 3.02-19.9). The mean hospital costs associated with preventing one case of death within 30 days from operation by undergoing DFR compared with ORIF was $176,021.39. Our results demonstrate higher rates of transfusion and increased inpatient costs among the DFR cohort compared with ORIF. However, we demonstrate lower rates of mortality for patients 80 years and older who underwent DFR versus ORIF. Future studies randomized controlled trials are necessary to validate the results of this study.

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.

Distal femoral replacement for the treatment of periprosthetic distal femoral fractures around a total knee arthroplasty: a meta-analysis. Orthop Rev (Pavia) 2024; 16:94574. [PMID: 38666188 PMCID: PMC11043028 DOI: 10.52965/001c.94574] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/12/2023] [Accepted: 02/02/2024] [Indexed: 04/28/2024] Open
Abstract
Background Periprosthetic fracture is a rare complication of arthroplasty but can have devastating consequences for the patient and presents a complex surgical challenge. Locking compression plate and retrograde intramedullary nail are both widely accepted surgical fixation techniques for distal femoral periprosthetic fractures around a total knee arthroplasty. Although there is still a need for further high-quality research into both techniques, there is even less literature concerning the use of distal femoral replacement to treat distal femoral periprosthetic fractures. Interest has been piqued in distal femoral replacements for the treatment of distal femoral periprosthetic fractures due to the theoretical advantages of immediate post-operative weight-bearing and lack of dependence on fracture union, but there are still understandably reservations about performing such an extensive and invasive procedure when an accepted alternative is available. This meta-analysis aims to evaluate the current literature to compare the complication rates and return to pre-operative ambulatory status of distal femoral replacement and locking compression plate. Method A literature search was performed to identify articles related to the management of distal femoral periprosthetic fractures around a total knee arthroplasty in adherence to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist. Methodological quality was assessed using the methodological index for non-randomized studies (MINORS) criteria. Articles were reviewed, and data extracted for analysis. Results Five articles met the inclusion criteria, reporting on 345 periprosthetic fractures. The overall rates of complications for distal femoral replacement and locking compression plate were: re-operation (6.1% vs 12.1%), infection (3.0% vs 5.3%), mortality (19.7% vs 19.3%), and return to pre-operative ambulatory status (60.9% vs 71.8%) (respectively). Conclusion This meta-analysis shows no statistically significant difference in the rates of re-operation, infection, mortality or return to pre-operative ambulatory status when comparing distal femoral replacement to locking compression plate.

Abstract
Background In extra-articular distal femoral fractures (EDFFs), nonunion is a serious complication that occurs rarely. In this study, we examined how longer preservation of initial fracture hematoma by delaying the osteosynthesis (OS) affects the fracture union. Methods In a retrospective cohort study, 98 EDFF patients were included. The OS was done within 2 days of injury in 50 patients (early OS group) and after 2 days of injury in 48 patients (late OS group). Time to callus formation and fracture union, bleeding amount, surgical duration, pain, knee range of motion, knee function, and postoperative complications, including the nonunion, knee deformity, infection, and revision, were compared between the 2 groups. Statistical analyses were done with SPSS. A comparison of the mean between the 2 groups was made with an independent t test or its nonparametric counterpart. A comparison of categorical variables between the 2 groups was made using a chi-square or the Fisher's exact test. P ˂ 0.05 was considered statistically significant. Results The mean time to callus formation was 47.1 ± 17.3 days in the early OS group and 46.9 ± 19.7 in the late OS group (P = 0.950). The mean time to fracture union was 114.9 ± 21 in the early OS group and 117.4 ± 28.8 days in the late OS group (P = 0.630). The mean operation time and bleeding amount between the 2 groups did not differ significantly (P = 0.230 and P = 0.340, respectively). The knee range of motion, pain, and function were not notably different (P = 0.620, P = 0.790, and P = 0.770, respectively). Nonunion occurred in 3 patients of early OS and 2 patients of the late OS group. Other complications were also comparable in the 2 study groups. Conclusion Delayed OA in EDFF patients has no significant effect on bone healing and fracture union. Future standard studies are required to confirm these results.

Early and 1-year mortality of native geriatric distal femur fractures: A systematic review and time-to-event meta-analysis. J Clin Orthop Trauma 2024; 50:102375. [PMID: 38495682 PMCID: PMC10943051 DOI: 10.1016/j.jcot.2024.102375] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/13/2023] [Revised: 12/27/2023] [Accepted: 02/19/2024] [Indexed: 03/19/2024] Open
Abstract
Purpose Distal femur fractures (DFF) account for 6% of all femoral fractures and predominate in females. The current 1-year mortality of DFF is currently reported to be between 10 and 38%, a wide margin, and confounded by multiple factors including age, high energy mechanisms, pathological and periprosthetic fractures. The purpose of this study was to assess and determine all-cause mortality following geriatric native distal femur fractures at 30 days, six months and one year. Methods - The databases Cochrane CENTRAL, MEDLINE, EMBASE and NHS NICE Healthcare Databases Advanced Search Interface were searched in accordance with PRISMA guidelines. Original research articles relevant to mortality outcomes in native geriatric distal femur fractures following low energy trauma were included. A time-to-event data meta-analysis model was used to estimate pooled 30-day, six month and one-year mortality. A random effects meta-regression model was performed to assess potential sources of heterogeneity when studies reported on factors affecting the mortality observed in patients with geriatric distal femur fractures. Results - Thirteen studies were included in the meta-analysis with a mean age of 79.6 years. Eight studies reported the 30-day mortality of distal femur fractures in patients as a pooled estimate of 8.14%. Pooled estimate for 6-month mortality reported was 19.5% and the one-year mortality reported by ten studies was 26.10%. Time-to-event modelling showed that risk of mortality at one year in elderly patients with distal femur fractures was significantly higher HR = 4.31 (p < 0.001). When evaluating prognostic predictors, age and Type C fracture were predictive of highest mortality rates. Conclusions - This study is the first meta-analysis to evaluate the early and long-term mortality observed in elderly patients presenting with native distal femoral fractures. Through our results we have shown the quantifiable impact patient age and fracture configuration has on one-year mortality in this patient cohort.

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

Abstract
BACKGROUND There is a paucity of data comparing periprosthetic hip fracture (PPHFx) outcomes and resource utilization to native fractures. Many surgeons consider periprosthetic hip fractures to be more severe injuries than native fractures. The aim of this systematic review is to characterize the outcomes of PPHFx and assess their severity relative to native hip fractures (NHFx). METHODS A Preferred Reporting Items for Systematic Reviews and Meta-Analysis systematic review was conducted using Medline, Biosis, and Cinahl. Primary outcomes were time to surgery, length of stay (LOS), cost of management, disposition, complication rates, readmission rates, and mortality. RESULTS 14 articles (13,489 patients) from 2010 to 2018 were included in the study. Study quality was generally low. Patient follow-up ranged from 1 month to 3.2 years. LOS ranged from 5.2 to 38 days. US cost of management was best estimated at $53,669 ± 19,817. Discharge to skilled nursing facilities ranged from 64.5 to 74.5%. Time to surgery ranged from 1.9 to 5.7 days. Readmission rates ranged from 12 to 32%. Per Clavien-Dindo classification, 33.9% suffered minor complications; 14.3% suffered major complications. 1 month and 1 year mortality ranged from 2.9% to 10% and 9.7% to 45%, respectively. CONCLUSION Time to surgery and LOS were longer for PPHFx relative to NHFx. Complications' rates were higher for PPHFx compared to NHFx. There is no evidence for differences in LOS, cost, discharge, readmission rates, or mortality between PPHFx and NHFx. These results may serve as a baseline in future evaluation of PPHFx management.

Abstract
PURPOSE This study aimed to estimate the mortality at various post-operative intervals and explore influential variables for these outcomes in elderly patients with distal femur fractures (DFF). METHODS A retrospective observational study was conducted across two tertiary care institutions, between 2014 and 2020. The primary outcomes were mortality rates at 30-day, six month, and one year post-surgery. Secondary outcomes included 1-year readmission and reintervention rates along with their correlated complications. RESULTS A total of 37 DFF in 35 patients was analyzed; average age was 83.6 years (range, 65-98 years). The overall mortality rate at a maximum follow-up of 8.8 years was 74% (26/35 patients). The median survival time was 3.2 years and the survival probability at five years was 27% (95% confidence interval [CI], 13 to 43%). Mortality rates at 30 days, six months, and one year after surgery were 8.6% (3 patients), 23% (8 patients), and 34% (12 patients), respectively. Overall mortality rate was 64% (15/24 patients) for native distal femur fractures, and 92% (13/14 patients) for periprosthetic fractures (p = 0.109). Patients older than 85 years and male gender were identified as risk factors for mortality within the first year post-operatively. CONCLUSION Elderly fractures have a high mortality at eight years of follow-up. Mortality at one year was much higher than in other studies of the same nature. We did not find statistically significant differences when comparing native bone fractures with periprosthetic fractures. Factors that impact mortality were being a man, advanced age, elevated index comorbidity, and dementia. There is no relationship between the time to be taken to the surgical procedure and mortality results.

Abstract
Background and objective Treating geriatric osteoporotic distal femur fractures has always presented challenges, but developing biodegradable materials has brought new opportunities for therapeutic intervention. Despite this progress, there currently needs to be more evidence-based biomechanical guidelines for using dual plate fixation and biodegradable materials in treating osteoporotic comminuted distal femoral fractures.In this study, finite element analysis was conducted to evaluate the mechanical effectiveness of different implant materials (titanium alloys, biodegradable materials, and combinations of both) in the fixation of physiological and osteoporotic distal femoral fractures. Methods We constructed finite element models of 33-C2 fractures and three types of plates: the Lateral Less Invasive Stabilization System (LISS) plate, the titanium-alloy medial plate (TAP), and the biodegradable plate (BP). To evaluate the biomechanical advantages in both physiological femur (PF) and osteoporotic femur (OF) conditions, three scenarios were developed: LISS + TAP, LISS + BP, and double biodegradable plates (DBPs). Five loading conditions were applied to measure structural stiffness, fracture micromotion, and implant stress: medio-lateral four-point bending, antero-posterior four-point bending, axial loading, torsional loading, and sideways falling. Several parameters were examined, including peak Von Mises Stress (VMS) of the femur and lateral plate, maximum displacement, bending angle, torsional angle of fracture, and risk of fracture. Results In four-point bending tests, the lateral plate of the DBPs group exhibited a slightly lower peak VMS compared to the LISS + TAP and LISS + BP groups. When subjected to axial loading, the stiffness values of the LISS + TAP (OF) were 1.42 times and 1.86 times higher than LISS + BP (OF) and DBPs (OF) groups, and the peak VMS of lateral plate of DBPs (OF) construct was approximately 2% and 16% lower than that of the LISS + TAP (OF) and LISS + BP (OF) constructs. Under torsional loading, DBPs (OF) demonstrated rotational stiffness that was respectively 2% and 52% greater than that of LISS + TAP (OF) and LISS + BP (OF). Regarding the peak VMS of femur, the values of DBPs (OF) were almost 8% and 15% lower than those of LISS + TAP (OF) and LISS + BP (OF). Conclusions The use of DBPs at 11.33 GPa facilitated early mobilization of load-bearing joints but exhibited limited ability to support full weight-bearing activities. Though LISS + TAP met practical strength requirements, one should consider the potential biological irritation and stress shielding. Thus, employing a combination of biodegradable and metal internal fixation is a valid approach to effectively treat weight-bearing joint fractures in clinical practice.

Comparison of radiological and functional results in osteoporotic distal femur fractures operated with single plating, lateral incision, and double plating, anterior paramedial incision: A retrospective study. Medicine (Baltimore) 2024; 103:e36904. [PMID: 38306559 PMCID: PMC10843363 DOI: 10.1097/md.0000000000036904] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/15/2023] [Accepted: 12/18/2023] [Indexed: 02/04/2024] Open
Abstract
Treatment of osteoporotic distal femur fractures is often complicated by a high rate of nonunion and varus collapse. For such fractures, lateral plating with lateral incision and double plating with anterior paramedial incision have shown promising results in the recent literature. The hypothesis of this study was that bilateral plating of comminuted distal femur fractures in osteoporotic patients would result in higher union rates and lower revision rates compared to an isolated lateral locking plate. The study included 56 patients (23 males, 33 females) with supracondylar femur fracture. According to the OA/OTA classification, 9 were type A3, 8 were A2, 13 were C1, 16 were C2, and 10 were C3. The mean follow-up period was 12 months, with 29 patients treated using lateral mini-incision, lateral locking plate, and 27 patients treated with anterior paramedial incision, dual plating. The clinical and radiological results were evaluated. The mean duration of radiological union in the studied population was 15 ± 2.1 months (range, 11-21 months) in the single plate group (Group A), and 13.5 ± 2.6 months (range, 9-19 months) in the double plate group (Group B). Mean ROM was 112.3° and flexion contracture 4° in Group A, and ROM 108.3° and flexion contracture 6.7° in Group B. (P = .15). The average Western Ontario and McMaster Universities Arthritis Index (WOMAC) score was 85.6 points in Group A and 83.5 points in Group B (P = .2278). The postoperative anteversion measurement in the operated extremity ranged from -15 to 19 in Group A, and from 5 to 18 in Group B. When the anteversion degrees were compared between the injured and uninjured extremities in the postoperative period, a significant difference was observed within Group A (P = .0018), but no significant difference was observed in Group B (P = .2492). Dual plate fixation using the anterior paramedial approach is an effective operative method for osteoporotic distal femur fractures. This has many advantages such as precise exposure, easy manipulation, anatomic reduction, and stable fixation. However, for surgical indications and medial bone defects > 1 cm, grafting should be performed.

Abstract
OBJECTIVES To compare clinical and radiographic outcomes after retrograde intramedullary nailing (rIMN) versus locked plating (LP) of "extreme distal" periprosthetic femur fractures, defined as those that contact or extend distal to the anterior flange. METHODS DESIGN Retrospective review. SETTING Eight academic level I trauma centers. PATIENT SELECTION CRITERIA Adult patients with periprosthetic distal femur fractures at or distal to the anterior flange (OTA/AO 33B-C[VB1]) treated with rIMN or LP. OUTCOME MEASURES AND COMPARISONS The primary outcome was reoperation to promote healing or to treat infection (reoperation for elective removal of symptomatic hardware was excluded from this analysis). Secondary outcomes included nonunion, delayed union, fixation failure, infection, overall reoperation rate, distal femoral alignment, and ambulatory status at final follow-up. Outcomes were compared between patients treated with rIMN or LP. RESULTS Seventy-one patients treated with rIMN and 224 patients treated with LP were included. The rIMN group had fewer points of fixation in the distal segment (rIMN: 3.5 ± 1.1 vs. LP: 6.0 ± 1.1, P < 0.001) and more patients who were allowed to weight-bear as tolerated immediately postoperatively (rIMN: 45%; LP: 9%, P < 0.01). Reoperation to promote union and/or treat infection was 8% in the rIMN group and 16% in the LP group ( P = 0.122). There were no significant differences in nonunion ( P > 0.999), delayed union ( P = 0.079), fixation failure ( P > 0.999), infection ( P = 0.084), or overall reoperation rate ( P > 0.999). Significantly more patients in the rIMN group were ambulatory without assistive devices at final follow-up (rIMN: 35%, LP: 18%, P = 0.008). CONCLUSIONS rIMN of extreme distal periprosthetic femur fractures has similar complication rates compared with LP, with a possible advantage of earlier return to weight-bearing. Surgeons can consider this treatment strategy in all fractures with stable implants and amenable prosthesis geometry, even extreme distal fractures. LEVEL OF EVIDENCE Therapeutic Level III.

Periprosthetic Distal Femoral Fractures Around a Total Knee Arthroplasty: a Meta-analysis Comparing Locking compression Plating and Retrograde Intramedullary Nailing. Orthop Rev (Pavia) 2024; 16:91507. [PMID: 38765295 PMCID: PMC10807720 DOI: 10.52965/001c.91507] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/27/2023] [Accepted: 12/10/2023] [Indexed: 05/22/2024] Open
Abstract
Purpose The number of total knee replacements (TKRs) performed per year has been increasing annually and it is estimated that by 2030 demand would reach 3.48 million procedures per year in the United States Of America. The prevalence of periprosthetic fractures (PPFs) around TKRs has followed this trend with incidences ranging from 0.3% to 3.5%. Distal femoral PPFs are associated with significant morbidity and mortality. When there is sufficient bone stock in the distal femur and a fracture pattern conducive to fixation, locking compression plating (LCP) and retrograde intramedullary nailing (RIMN) are commonly used fixation strategies. Conversely, in situations with loosening and deficient bone stock, a salvage procedure such as a distal femoral replacement is recognized as an alternative. This meta-analysis investigates the rates of non-union, re-operation, infection, and mortality for LCPs and RIMNs when performed for distal femoral PPFs fractures around TKRs. Method A search was conducted to identify articles relevant to the management of distal femoral PPFs around TKRs in adherence to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist. Articles meeting the inclusion criteria were then assessed for methodological quality using the methodological items for non-randomised studies (MINORS) criteria. Articles were reviewed, and data were compiled into tables for analysis. Results 10 articles met the inclusion criteria, reporting on 528 PPFs. The overall incidence of complications was: non-union 9.4%, re-operation 12.9%, infection 2.4%, and mortality 5.5%. This meta-analysis found no significant differences between RIMN and LCP in rates of non-union (9.2% vs 9.6%) re-operation (15.1% vs 11.3%), infection (2.1% vs 2.6%), and mortality (6.0% vs 5.2%), respectively. Conclusion This meta-analysis demonstrated no significant difference in rates of non-union, re-operation, infection, and mortality between RIMN and LCP and both remain valid surgical treatment options.

Abstract
INTRODUCTION Geriatric fractures including distal femur and hip fractures are associated with high mortality rates. Currently, prognostic factors for in-hospital postoperative mortality are not identified. We aimed to evaluate overall in-hospital mortality and related potential risk factors in elderly patients who underwent distal femur fracture surgery. MATERIALS AND METHODS A retrospective cohort study of patients older than 60 years, who underwent distal femur fracture surgery between January 01, 2003, and December 31, 2021, was conducted. A case-control study was conducted to compare two age-matched groups of elderly patients of equivalent ages at a 1:4 ratio. The in-hospital mortality rate was calculated and potential confounders were compared between groups. RESULTS A total of 170 patients were enrolled; five died during hospital stay after undergoing surgery, yielding a 2.94% in-hospital mortality rate. Twenty patients who did not die were included in the control group. Patients' demographics were similar. The case-control comparison showed that the time from injury to surgery, preoperative hemoglobin level, estimated glomerular filtration rate (eGFR), and white blood cell count were significant factors correlated with in-hospital mortality. DISCUSSION The overall in-hospital mortality rate was 2.94%. Significant risk factors for in-hospital mortality included a longer time from injury to surgery, lower preoperative hemoglobin level and eGFR, and higher preoperative white blood cell count. In conclusion, preoperative comprehensive geriatric assessment, including cognitive, nutritional, and frailty status, should also be considered in the elderly fracture care model.

Abstract
BACKGROUND Due to the increase in hip and knee prosthetic as a result of the demographic changes, with raised levels of activity among older persons with geriatric comorbidities, a continuous increase in periprosthetic fractures can be observed. OBJECTIVE The incidence and causes of periprosthetic fractures, presentation of diagnostic pathways and derivation of a recommendation according to generally accepted classifications. MATERIAL AND METHOD Literature search of basic scientific work, recommendations of experts as well as evaluation of own patient collective. CONCLUSION With a growing number of prosthetic interventions in combination with increasing patient age, an increase in periprosthetic fractures is to be expected. The treatment of periprosthetic fractures is complex and requires detailed analysis of the location of the fracture and its morphology as well as the recognition of possibly loosened prosthetic material. Based on this information, the correct surgical treatment can be determined and scheduled in an appropriate center of care. In geriatric patients with corresponding comorbidities, an individual holistic treatment plan should be developed.

EUROPEAN JOURNAL OF ORTHOPAEDIC SURGERY & TRAUMATOLOGY : ORTHOPEDIE TRAUMATOLOGIE 2023; 33:3215-3223. [PMID: 37106139 DOI: 10.1007/s00590-023-03552-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/21/2023] [Accepted: 04/10/2023] [Indexed: 04/29/2023]
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
Primary arthroplasty for fractures of the femoral neck is a very common procedure and even the gold standard for the geriatric patient. In contrast, primary arthroplasty for perigenicular fractures is a rare event. On the other hand, it can be a therapeutic option, especially for geriatric patients with prior osteoarthritis or complex fractures and severe osteoporosis.The operative procedure can be complex and requires experience in primary and revision arthroplasty as well as suitable implants and good preoperative planning.There are case series reporting primary arthroplasty in a total of approximately 200 cases of both distal femoral and proximal tibial fractures. Complication rates are between 0 and 90% and mostly concern wound healing problems and infections. From a functional point of view, predominantly good results and a range of motion of 100° can be achieved.Primary arthroplasty can be a therapeutic option for selected cases of perigenicular fractures and gives good functional results. The most frequent complications are wound healing problems and infections.

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
BACKGROUND The locking plate is a common device to treat distal femur fractures. Healing is affected by construct stiffness, thus many surgeon-controlled variables such as working length have been examined for their effects on strain at the fracture. No convenient analytical model which aids surgeons in determining working length has yet been described. We propose an analytical model and compare it to finite element analysis and cadaveric biomechanical testing. METHODS First, an analytical model based on a cantilever beam equation was derived. Next, a finite element model was developed based on a CT scan of a "fresh-frozen" cadaveric femur. Third, biomechanical testing in single-leg stance loading was performed on the cadaver. In all methods, strain at the fracture was recorded. An ANCOVA test was conducted to compare the strains. FINDINGS In all models, as the working length increased so did strain. For strain at the fracture, the shortest working length (35 mm) had a strain of 8% in the analytical model, 9% in the finite element model, and 7% for the cadaver. The longest working length (140 mm) demonstrated strain of 15% in the analytical model, and the finite element and biomechanical tests both demonstrated strain of 14%. INTERPRETATION The strain predicted by the analytical model was consistent with the strain observed in both the finite element and biomechanical models. As demonstrated in existing literature, increasing the working length increases strain at the fracture site. Additional work is required to refine and establish validity and reliability of the analytical model.

Abstract
Background Acetabular fractures among the elderly are common. Identification of risk factors predisposing elderly patients to in-hospital complications is critical to mitigating morbidity and mortality. Methods A retrospective cohort study was performed including 195 patients ≥60 years old who sustained acetabulum fractures treated at a single level 1 trauma center. Operative (n=110, 56.4%) or non-operative management was undertaken, and complications during the index hospitalization were defined. Results Seventy-three patients (37%) developed a complication during their hospitalization. Most common complications were acute respiratory failure: 13.3%, pneumonia: 10.3%, urinary tract infection: 10.3%, cardiac dysrhythmia: 9.7%, and acute kidney injury: 6.2%. On multivariable analysis, factors associated with in-hospital complications were increased age (adjusted OR (AOR): 1.06, 95% CI: 1.01 to 1.11, p=0.013), more comorbidities (AOR: 1.69, 95% CI: 1.07 to 2.65, p=0.024), operative management (AOR: 0.3, 95% CI: 0.12 to 0.76, p=0.011), and increased length of stay (AOR: 1.34, 95% CI: 1.2 to 1.51, p<0.001). Conclusions Acetabular fractures in the elderly are associated with high rates of in-hospital complications. Advanced age, more medical comorbidities and longer lengths of stay predicted higher risk of developing complications. Whereas operative management was associated with lower risk of developing complications during the initial admission, it is important to note the selection bias in which healthier patients with improved baseline functionality may be more likely to undergo operative management. Level of evidence Level III therapeutic.

Abstract
Background Restricted weight-bearing is still used after lower extremity fracture surgery in elderly patients. The long-term effect on gait recovery in elderly patients with distal femur fractures (DFF) and their ability to comply with the restrictive weight-bearing regime is unknown. This study aimed to investigate the effect of restricted postoperative weight-bearing on gait recovery (actual weight-bearing and cadence) during a 1-year follow-up. Methods This study evaluated secondary outcomes from a randomized controlled trial (32 patients ≥65 years, with a traumatic DFF). Internal fixation was achieved using an anatomical lateral plate. Patients were allocated to either immediate full weight-bearing (FWB) or partial weight-bearing (PWB) (30% of body weight) for 8 weeks. Pressure-sensitive sensors (F-scan™ system, Tekscan, Massachusetts, USA) were used to measure weight-bearing and cadence postoperatively and at 8-, 16-, and 52-week follow-ups. Twenty-six patients with at least 1 measurement were included. Results There was a statistically significant difference in actual weight-bearing between the PWB and FWB groups postoperatively of 32.3% (95% confidence interval CI, -50.0; -13.0, P < .001) and at the 8-week follow-up of 36.8% (95% CI -61.0; -18.0, P = .01), but not at later follow-ups. The PWB group presented a consistently lower cadence compared to the FWB group, which was statistically significant at the 16-week follow-up with 9.0 steps/min (95% CI -16.2; -1.1, P = .047) and 52-week follow-up with 9.3 steps/min (95% CI -18.0; -3.9, P = .009). Conclusions Restricting postoperative weight-bearing in elderly patients with a DFF had a significant effect on postoperative weight-bearing. The effect lingered with a delayed return to FWB and persistent significantly lower cadence in the PWB group. These findings suggest that even temporary weight-bearing restrictions most likely have negative long-term effects on gait function at 1 year and, therefore, cannot be recommended.

Abstract
OBJECTIVE Comparing outcomes of periprosthetic distal femur fractures treated with open reduction and internal fixation (ORIF) versus distal femoral replacement (DFR). SETTING Three major academic hospitals within one metropolitan area. DESIGN Retrospective. PATIENTS/PARTICIPANTS Three hundred seventy patients >64 years old with periprosthetic distal femur fractures were identified and 115 were included (65 ORIF vs. 50 DFR). INTERVENTION ORIF with locked plating versus DFR. MAIN OUTCOME MEASUREMENT One-year mortality, ambulatory status at 1 year, reoperations, and hospital readmissions. RESULTS No differences were observed between ORIF and DFR cohorts regarding demographics or medical history, including Charleston Comorbidity Index. DFR was associated with longer hospital stay (6.09 days ORIF vs. 9.08 days DFR, P < 0.001) and more frequent blood transfusion (12.3% ORIF vs. 44.0% DFR, P < 0.001). Logistic regression analysis using propensity score matching (PSM) demonstrated no statistically significant difference in reoperation, hospital readmission, ambulatory status at 1 year, or 1-year mortality between the 2 cohorts. Finally, applying Bayesian model averaging using PSM to identify risk factors for 1-year mortality demonstrated that increasing age, length of index hospital stay, and 90-day hospital readmission were significantly associated with 1-year mortality, regardless of type of surgical treatment. CONCLUSION Rehospitalization, reoperation, ambulatory status, and 1-year mortality are no different between ORIF and DFR in the treatment of geriatric periprosthetic distal femur fractures when PSM is applied to mitigate selection bias. Further study is warranted to elucidate functional outcomes, long-term sequelae, and costs of care related to these treatment options to better guide treatment planning.

Abstract
OBJECTIVE Compare mortality and complications of distal femur fracture repair among elderly patients who receive operative fixation versus distal femur replacement (DFR). DESIGN Retrospective comparison. SETTING Medicare beneficiaries. PATIENTS/PARTICIPANTS Patients 65 years of age and older with distal femur fracture identified using Center for Medicare & Medicaid Services data from 2016 to 2019. INTERVENTION Operative fixation (open reduction with plating or intramedullary nail) or DFR. MAIN OUTCOME MEASUREMENTS Mortality, readmissions, perioperative complications, and 90-day cost were compared between groups using Mahalanobis nearest-neighbor matching to account for differences in age, sex, race, and the Charlson Comorbidity Index. RESULTS Most patients (90%, 28,251/31,380) received operative fixation. Patients in the fixation group were significantly older (81.1 vs. 80.4 years, P < 0.001), and there were more an open fractures (1.6% vs. 0.5%, P < 0.001). There were no differences in 90-day (difference: 1.2% [-0.5% to 3%], P = 0.16), 6-month (difference: 0.6% [-1.5% to 2.7%], P = 0.59), and 1-year mortality (difference: -3.3% [-2.9 to 2.3], P = 0.80). DFR had greater 90-day (difference: 5.4% [2.8%-8.1%], P < 0.001), 6-month (difference: 6.5% [3.1%-9.9%], P < 0.001), and 1-year readmission (difference: 5.5% [2.2-8.7], P = 0.001). DFR had significantly greater rates of infection, pulmonary embolism, deep vein thrombosis, and device-related complication within 1 year from surgery. DFR ($57,894) was significantly more expensive than operative fixation ($46,016; P < 0.001) during the total 90-day episode. CONCLUSIONS Elderly patients with distal femur fracture have a 22.5% 1-year mortality rate. DFR was associated with significantly greater infection, device-related complication, pulmonary embolism, deep vein thrombosis, cost, and readmission within 90 days, 6 months, and 1 year of surgery.

Abstract
INTRODUCTION Varus collapse followed by osteosynthesis for distal femoral fractures with conventional implants has been well documented but is seldom mentioned in fractures managed with locking plates. The purpose of this study was to assess the incidence of varus collapse after treating complex supra-intercondylar fractures of the distal femur (AO type C3) using a Single Plate (SP) or Double Plate (DP) fixation technique. MATERIALS AND METHODS We retrospectively reviewed 357 patients with distal femoral fractures who were treated at our hospital between 2006 and 2017. After excluding cases of infection, malignancy, periprosthetic fracture, revision surgery, pediatric fracture, and extra-articular fracture, 54 patients were included in the study. All demographic data and radiological and clinical outcomes were reviewed and analyzed. RESULTS There were 54 patients enrolled into this study with age from 15 to 85 years old (mean 41.6, SD = 19.9), and 32 of them were open fractures (59%). The patients were further divided into either an SP (n = 15) or a DP group (n = 39). Demographics, including age, sex, injury severity score, and open fracture type, were all compatible between the two groups. The overall nonunion rate was 25.9% (n = 14; 6 from the SP and 8 from the DP group; p = 0.175). The varus collapse rate was 9.3% (n = 5; 4 from the SP and 1 from the DP group (p = 0.018). CONCLUSIONS The varus collapse rate after osteosynthesis with a single lateral locking plate could be as high as 26.7% in AO type C3 fractures of the distal femur, which would be decreased to 2.6% by adding a medial buttress plate. Surgeons should consider DP fixation to avoid varus collapse in severely comminuted complete intra-articular fractures of the distal femur.

Abstract
OBJECTIVES To compare fracture incidence, mortality, and patient-reported health outcomes at 6 and 12 months postinjury between primary and periprosthetic distal femur fractures in older adults. METHODS A registry-based cohort study was conducted including all adults 70 years of age or older registered by the Victorian Orthopaedic Trauma Outcomes Registry who experienced a primary or periprosthetic distal femur fracture between 2007 and 2017. Outcomes included mortality and health status (Three-Level European Quality of Life-Five Dimensions Scale [EQ-5D-3L]) collected at 6 and 12 months postinjury. All distal femur fractures were confirmed by radiological review. Multivariable logistic regression was conducted to report associations between fracture type and mortality and health status. RESULTS A final cohort of 292 participants was identified. Overall mortality for the cohort was 29.8%, and no significant differences were found in mortality rate or EQ-5D-3L outcomes between fracture types (ie, primary vs. periprosthetic). A large proportion of participants reported problems across all EQ-5D-3L domains at 6 and 12 months postinjury, with slightly worse outcomes in the primary fracture group. CONCLUSIONS This study reports high mortality and poor 12-month outcomes in an older adult cohort with both periprosthetic and primary distal femur fractures. Given these poor outcomes, fracture prevention and a greater focus on long-term rehabilitation is needed in this cohort. In addition, the involvement of an ortho-geriatrician should be considered as a routine component of care. LEVEL OF EVIDENCE Prognostic Level III.

Abstract
BACKGROUND Supracondylar periprosthetic fractures, when amenable to fixation, can be treated by either retrograde intramedullary nailing (RIMN) or plating. There is paucity of evidence regarding the superiority of one fixation method over the other. This review aims to determine which fixation method leads to better functional outcomes and perioperative complications. HYPOTHESIS Superiority of intramedullary nailing in terms of fracture healing and surgical complications when compared to distal femoral plating. MATERIALS AND METHODS Using PRISMA guidelines, a systematic search was performed. Studies which reported comparative outcome data following the two interventions were included. Qualitative data analysis and narrative synthesis were reported. Pooled comparisons were conducted when similar quantifiable outcomes were reported in a minimum of three studies. RESULTS A total of 151 records were generated by the search. Eight studies met the eligibility criteria so were included in the final analysis. The studies comprised a total of 407 cases, with a follow up period ranging from 1 to 15 years. 252 cases were treated with plate fixation and 155 with RIMN. All studies were mitigated by heterogeneity and methodological limitations. The review showed marked variation in descriptive fracture classifications. Narrative data synthesis was conducted. Although guarded by the methodological limitations of individual studies, outcomes showed that mean time to union was equivalent; 5.88 months for RIMN compared to 6.75 months in plating, standardised mean difference=0.28 (95% CI -0.02-0.58). Similarly, no statistically significant differences were reported between RIMN and plating for deep infection (OR:1.41 95%CI 0.40-5.00) and revision surgery (OR: 0.74, 95%CI 0.39-1.41). DISCUSSION Clinical outcomes showed a tendency that favours intramedullary nailing; however, generalisation of results was not possible. Future priority must be awarded to higher quality research in the form of a collaborative multicentre observational studies to delineate appropriate major diagnostic categories, ultimately informing a large comparative trial using condition specific validated outcome measures.

Abstract
BACKGROUND The United Kingdom has an aging population with nearly 1 in 5 being over the age of 65, and over 0.5 million over the age of 90. The treatment of acute fractures of the lower limb in the nonagenarian cohort of patients poses a technical challenge to orthopaedic surgeons. AIM To report the fracture incidence, survival outcomes of treating acute non-hip lower limb fractures in nonagenarians in Major Trauma Centre. METHODS Thirty Lower limb long bone fractures in patients of age from 90 to 99 years were identified during 12-mo at a Level 1 trauma centre from a computerized database. A retrospective evaluation performed for fracture incidence, treatment, length of hospital duration and mortality at 30-d, 1-year and 2-year. RESULTS Thirty fractures (28 patients) were identified, twenty-four fractures were treated with surgery (mean age 93 years SD ± 2.59) and 6 managed conservatively (mean age 94 years SD ± 2.07). The mean length of the hospital stay was 18.2 d for both groups. The 30-d, 1-year and 2-year mortality risks were 1/23, 6/23 and 9/23 (4%, 26% and 39%) in the surgery group and 0/5, 1/5 and 2/5 (0%, 20% and 40%) in the conservative group, with no evidence for a difference between the two groups at any time point. CONCLUSION Nonagenarians in the surgical group had similar length of hospital stay and mortality risks as those treated conservatively. Patients with fewer comorbidities and admitted from their own home were offered surgery.

Abstract
Introduction The purpose of this study was to identify the timing and nature of complications associated with distal femur fracture surgery in patients aged 65 and older using the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) database. Methods The ACS NSQIP database was queried for adults aged 65 and older who received surgical treatment for a distal femur fracture between 01 January 2015 and 31 December 2021. Cox regression models and risk tables adjusted for baseline clinical characteristics were created for 14 complications (Superficial Surgical Site Infection (SSI), Deep SSI, Organ/Space SSI, Pneumonia, Pulmonary Embolism (PE), Deep Venous Thrombosis (DVT), Urinary Tract Infection (UTI), Stroke/Cerebrovascular accident (CVA), Myocardial Infarction (MI), Renal Failure, Cardiac Arrest (CA), Re-operation, Sepsis, and Death within 30 days of surgery). Model summaries were used to identify significant variables with a Bonferroni correction applied. Results A total of 3956 adults met inclusion criteria and were included in analysis. The most common complications were UTI (5.2%), death (4.1%), and pneumonia (3.4%). Complications typically occurred within 14 days after surgery, except for SSI, which occurred between post-op days 11 and 24. Conclusions Distal femur fractures are a substantial source of morbidity and mortality in the older adult population. Our findings underscore the need for comprehensive preoperative risk assessment and patient management strategies to mitigate the impact of identified risk factors in this vulnerable population.

Abstract
Aims Several previously identified patient-, injury-, and treatment-related factors are associated with the development of nonunion in distal femur fractures. However, the predictive value of these factors is not well defined. We aimed to assess the predictive ability of previously identified risk factors in the development of nonunion leading to secondary surgery in distal femur fractures. Methods We conducted a retrospective cohort study of adult patients with traumatic distal femur fracture treated with lateral locking plate between 2009 and 2018. The patients who underwent secondary surgery due to fracture healing problem or plate failure were considered having nonunion. Background knowledge of risk factors of distal femur fracture nonunion based on previous literature was used to form an initial set of variables. A logistic regression model was used with previously identified patient- and injury-related variables (age, sex, BMI, diabetes, smoking, periprosthetic fracture, open fracture, trauma energy, fracture zone length, fracture comminution, medial side comminution) in the first analysis and with treatment-related variables (different surgeon-controlled factors, e.g. plate length, screw placement, and proximal fixation) in the second analysis to predict the nonunion leading to secondary surgery in distal femur fractures. Results We were able to include 299 fractures in 291 patients. Altogether, 31/299 fractures (10%) developed nonunion. In the first analysis, pseudo-R2 was 0.27 and area under the receiver operating characteristic curve (AUC) was 0.81. BMI was the most important variable in the prediction. In the second analysis, pseudo-R2 was 0.06 and AUC was 0.67. Plate length was the most important variable in the prediction. Conclusion The model including patient- and injury-related factors had moderate fit and predictive ability in the prediction of distal femur fracture nonunion leading to secondary surgery. BMI was the most important variable in prediction of nonunion. Surgeon-controlled factors had a minor role in prediction of nonunion.

Clin Orthop Relat Res 2023; 481:967-973. [PMID: 36728246 PMCID: PMC10097580 DOI: 10.1097/corr.0000000000002516] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/25/2022] [Accepted: 11/14/2022] [Indexed: 02/03/2023]
Abstract
BACKGROUND The outcomes of orthopaedic trauma are not solely determined by injury severity or surgical treatment. Studies of numerous orthopaedic outcomes have found that psychosocial factors are also important. Symptoms of anxiety have been linked to long-term pain and disability. Although the existence of a relationship between psychosocial factors and functional outcomes is accepted across multiple disciplines, quantification of this association in patients who have experienced orthopaedic trauma has remained limited. Measuring the anxiety experienced by these individuals and the association with long-term functional outcomes remain poorly understood. QUESTIONS/PURPOSES (1) Is there an association between early postoperative anxiety symptoms and late recovery of self-reported physical function in patients with orthopaedic trauma? (2) What was the impact of other factors such as demographic variables and comorbidities on late recovery physical function scores, and how did the magnitude of these factors compare with the association with anxiety score? (3) Did patients who presented as trauma activations differ regarding their anxiety symptoms and late-recovery self-reported physical function? METHODS A total of 1550 patients with lower extremity fractures and postoperative Patient-Reported Outcomes Measurement Information System (PROMIS) anxiety and physical function scores treated between January 1, 2014, and January 1, 2021, at an academic Level I trauma center in North America were assessed. We performed a bivariate regression between the initial PROMIS anxiety and physical function, as well as a multivariate regression including age, gender, BMI, and American Society of Anesthesiologists class to control for potential confounding variables. In a subgroup of 787 patients presenting as trauma activations, we performed a separate regression including Injury Severity Score. RESULTS PROMIS anxiety was associated with decreased late-recovery physical function (β = -2.64 [95% CI -3.006 to -2.205]; p < 0.001). The relationship between PROMIS anxiety and physical function remained after controlling for confounding variables in our overall cohort (β = -2.54 [95% CI -2.93 to -2.15]; p < 0.001) and in the trauma activation cohort (β = -2.71 [95% CI -3.19 to -2.23]; p < 0.001). Age and American Society of Anesthesiologists score were associated with worse PROMIS physical function scores, while being a man was associated with better PROMIS physical function scores (age: β= -1.26 [95% CI -1.50 to -1.02]; American Society of Anesthesiologists class: β=-2.99 [95% CI -3.52 to -2.46]; men: β = 0.95 [95% CI 0.16 to 1.75]). There were no differences in initial anxiety symptoms or late-recovery physical function between patients who presented as trauma activations and those who did not. Injury Severity Scores were independently associated with worse function (β = -1.45 [95% CI -2.11 to -0.79]. CONCLUSION Initial patient self-reported anxiety is negatively associated with patient-reported physical function at the final follow-up interval in a broad cohort of patients with orthopaedic lower extremity injuries undergoing surgery. Identifying patients with high initial PROMIS anxiety scores may allow us to determine which patients will report lower functional scores at the final follow-up. Future investigations could focus on the effect of psychosocial interventions such as cognitive behavioral therapy and mindfulness on functional scores.

Abstract
Periprosthetic fractures around a total knee arthroplasty (TKA), comminuted and intra-articular femur fractures, or fracture nonunions in osteoporotic bone represent technically challenging problems. This is particularly true when the fracture involves a loose femoral component or the pattern results in suboptimal fixation potential. These clinical indications often arise in an older and comorbid patient population in whom a principal goal of treatment includes allowing for early mobilization. Limited data indicate that arthroplasty via distal femoral replacement (DFR) is a reasonable alternative to open reduction and internal fixation, allowing for early ambulation with low complication rates. We performed a retrospective review of trauma and arthroplasty surgeries at three tertiary referral institutions. Adult patients treated for the above with a DFR were included. Patients with active infection, open and/or high-energy injuries and revisions unrelated to fracture were excluded. Patient demographics, treatment details, and outcomes were assessed. Between 2002 and 2017, 90 DFR's were performed for the above indications with a mean follow-up of 24 months. Postoperatively, 80 patients (88%) were allowed to weight bear as tolerated, and at final follow-up, 9 patients (10%) remained dependent on a wheelchair. The average arc of motion at final follow-up was 95 degrees. There were seven (8%) implant-related complications requiring secondary surgeries: two infections, one with associated component loosening; one fracture of the hinge mechanism and one femoral component failure in conjunction with a patellofemoral dislocation (both requiring revision); one case of patellofemoral arthrosis in a patient with an unresurfaced patella; one periprosthetic fracture with associated wound dehiscence; and one case of arthrofibrosis. In each of these cases, only modular components of the DFR were exchanged. All nonmodular components cemented into the femur or tibia were retained. DFR provides a viable reconstruction option in the treatment of acute distal femur fractures, periprosthetic femur fractures, and fracture nonunions. We noted that in an elderly patient population with high comorbidities, the complication and secondary surgery rates remained relatively low, while allowing for immediate weight bearing.

Short-term outcomes of periprosthetic compared to native distal femur fractures, a national database study. Arch Orthop Trauma Surg 2023; 143:115-124.

Abstract
BACKGROUND Distal femur fractures (DFFx) are highly morbid injuries with a complication rate comparable to hip fractures. Rising rates of total knee arthroplasty (TKA) have led to increasing rates of periprosthetic DFFx (pDFFx). We sought to determine how pDFFx complication rates differed from native DFFx (nDFFx). METHODS The American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) was used to identify patients who sustained pDFFx or nDFFx between 2012 and 2018. Patients were further stratified by operative treatment: open reduction internal fixation (ORIF) or distal femur replacement (DFR). Multivariate logistic regression was used to compare 30-day complication rates between pDFFx versus nDFFx and, among pDFFx patients, ORIF versus DFR or revision TKA (rTKA). RESULTS 563 patients with pDFFx and 2259 patients with nDFFx were identified between 2012 and 2018. pDFFx patients had significantly lower rates of ORIF than nDFFx patients (36.4 vs 95.4%, p < 0.001). On multivariate analysis, pDFFx were associated with a higher rate of surgical site complications (OR 2.48, p = 0.009) compared to nDFFx. There were no differences in mortality, reoperations, major complications, rate of blood transfusion, venous thromboembolism and disposition. In patients with pDFFx, patients undergoing DFR/rTKA were more likely to be discharged home versus a rehab facility, compared to those undergoing ORIF (OR 2.62, p < 0.001). CONCLUSIONS In this first large registry study comparing pDFFx and nDFFx, we find similar outcomes between these groups in the first 30 days after surgery. Patients with pDFFx did have higher rates of surgical site complications, including infection and dehiscence. In pDFFx patients, those undergoing DFR were more likely to return home post-operatively.

Biomechanical and anatomical considerations for dual plating of distal femur fractures: a systematic literature review. Arch Orthop Trauma Surg 2022; 142:2597-2609.

Abstract
INTRODUCTION Distal femur fractures are challenging injuries historically associated with high rates of nonunion and varus collapse with operative management. As a result, clinical and research interest in dual plating (DP) of distal femur fractures has seen a dramatic increase in recent years. The purpose of this study was to systematically review the literature regarding vascular anatomy and biomechanics of distal femur fractures treated with DP constructs. MATERIALS AND METHODS A systematic literature review of two medical databases (PubMed & Scopus) was performed to identify peer-reviewed studies on the anatomy and biomechanics regarding DP of distal femur fractures. A total of 1,001 papers were evaluated and 14 papers met inclusion criteria (6 anatomy and 8 biomechanics). Methodological quality scores were used to assess quality and potential bias in the included studies. RESULTS In the biomechanical studies, DP constructs demonstrated greater axial and rotational stiffness, as well as less displacement and fewer incidences of failure compared to all other constructs. Vascular studies showed that the femoral artery crosses the mid-shaft femur approximately 16.0-18.8 cm proximal to the adductor tubercle and it is located on average 16.6-31.1 mm from the femoral shaft at this location, suggesting that medial plate application can be achieved safely in the distal femur. The methodological quality of the included studies was good for biomechanical studies (Traa score 79.1; range 53-92.5) and excellent for anatomical studies (QUACs score 81.9; range 69.0-88.5). CONCLUSIONS Existing biomechanics literature suggests that DP constructs are mechanically stronger than other constructs commonly used in the treatment of distal femur fractures. Furthermore, medial distal femoral anatomy allows for safe application of DP constructs, even in a minimally invasive fashion. Dual plating should be considered for patients with distal femur fractures that have risk factors for instability, varus collapse, or nonunion.

One-Year Mortality Rates Following Fragility Femoral Fractures in Patients Presenting to King Saud Medical City in Riyadh, Saudi Arabia: A Retrospective Study. Cureus 2022; 14:e28844.

Abstract
Objective: The objective is to investigate one-year mortality rates following femur osteoporotic fractures, and to investigate factors that are associated with higher mortality rates. Design: A retrospective study was conducted from 2010 to 2021 (11 years) of all patients who presented to King Saud Medical City, Saudi Arabia, and had a fragility fracture of the proximal or distal femur. Patients: One hundred eight patients who sustained a proximal or distal femoral fracture, as a result of low-energy trauma, were included. Results: The majority of our cohort (77.8%) had proximal femoral fractures, whereas only 22.2% had a distal femoral fracture. 55.6% were less than 75 years old, and 44.4% were 75 years or older. All patients had fallen from standing height. Hypertension and diabetes were the most common comorbidities among our cohort at 49.1% and 47.2%, respectively, but neither showed a statistically significant increase in the risk of mortality. When assessing the overall mortality, 21.3% of our patients had passed away. Although this finding was not statistically significant, mortality rates were found to be higher in patients with proximal femoral fractures compared to distal femoral fractures (25% vs. 8.3%, respectively, p=0.095). Patients with a normal bone mass density (BMD) had higher mortality rates as opposed to those with abnormal BMD (p=0.001). Conclusions: Mortality rates are higher in proximal femoral fractures compared to distal femoral fractures. In addition, within our study cohort, patients with normal BMD had higher mortality rates. We recommend prospective studies that compare mortality rates between proximal and distal femoral fractures in patients with osteoporosis, as these studies would provide more accurate data. We also recommend having BMD measured in those patients to avoid further fractures in this patient population.

Abstract
BACKGROUND Necrotizing fasciitis (NF) is a life-threatening and acute progressive soft tissue infection and needs early surgical intervention, that is, debridement or amputation. Surgical strategy or prognosis is influenced by the speed of progression and patients' general condition, which can be calculated by the Charlson Comorbidity Index (CCI). The purpose of this study was to investigate the association between the CCI scores and prognosis of patients with NF of the upper/lower extremities. METHODS In the retrospective cohort study, we analyzed patients with NF of the upper/lower extremities who were determined to undergo surgery by orthopedic surgeons at four tertiary hospitals between August 2003 and April 2016. We divided the patients into two groups, Group L (low CCI scores of 0-2) and Group H (high CCI scores of ≥3). The primary event of this study was defined as death or amputation. Mortality cases were included when amputation was informed with documented certification but patients died while waiting for surgery. We compared the patients' background, laboratory data on admission, the laboratory risk indicator for necrotizing fasciitis (LRINEC) score, and primary outcome between the two groups. RESULTS Of the 56 patients, 28 patients were classified into Group L and the other 28 patients into Group H. The data in this study showed that patients in Group H had lower white blood cell counts and hemoglobin and higher creatinine than Group L, but there was no difference in LRINEC scores between the two groups. Streptococcus pyogenes was the most common infectious agent in Group L (54%) but not in Group H (11%). Poorer outcome was observed in Group H compared with Group L (4 mortality and 16 amputation vs. no mortality and 9 amputation, P = 0.007). CONCLUSIONS Laboratory data and causative microorganisms were different between high CCI and low CCI patients with NF. High CCI scores were associated with limb amputation or death caused by NF of the upper/lower extremities; whereas, low CCI scores were more likely associated with S. pyogenes monoinfection.

Abstract
While fractures of the distal femur are often considered as fragility fractures, detailed knowledge of the bone microarchitecture at this skeletal site is largely unavailable. Initial evaluation of a patient cohort with distal femur fractures showed a markedly increased occurrence in elderly women. The purpose of this study was to determine the extent to which demographic characteristics of distal femur fractures are reflected by general age- and sex-specific variations in local microarchitectural parameters. Fifty cadaveric femora were collected from 25 subjects (12 females, 13 males, age 25-97 years). A volume of interest within 3 cm proximal to the condyles was analyzed using high-resolution peripheral quantitative computed tomography (HR-pQCT), which revealed impaired trabecular and cortical bone microarchitecture in women compared to men as well as in osteoporotic compared to normal or osteopenic subjects, as classified by dual-energy X-ray absorptiometry (DXA) T-score. Linear regression analyzes showed negative associations between age and HR-pQCT parameters in women (e.g., cortical thickness -14 µm/year, 95% CI: -21 to -7 µm/year), but not in men (e.g., cortical thickness 1 µm/year, 95% CI: -12 to 14 µm/year). HR-pQCT parameters showed strong positive associations with areal bone mineral density (aBMD) determined by DXA at the hip in both sexes. Taken together, our findings suggest that female sex, advanced age, and low aBMD represent major risk factors for impaired microarchitecture at the distal femur. Both the diagnostic value of DXA for predicting distal femur fractures and the efficacy of bone-specific agents on fracture risk reduction should be investigated in the future.

[PMID: 33938985 DOI: 10.1007/s00402-021-03892-2] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/06/2021] [Accepted: 03/31/2021] [Indexed: 12/15/2022]
Abstract
INTRODUCTION Regional anesthesia (RA) is sometimes used to decrease pain and opioid consumption in distal femur fractures. However, the real-world impact of RA on inpatient opioid consumption and outpatient opioid demand is not well known. The hypothesis of this study is that RA would be associated with decreased inpatient opioid consumption and outpatient opioid demand. METHODS This study evaluated inpatient post-operative opioid consumption (0-24 h, 24-48 h, 48-72 h) and outpatient opioid demand (discharge to 2 weeks, 6 weeks, and 90 days) in all patients ages 18 and older undergoing operative treatment of distal femur fractures at a single institution from 7/2013 to 7/2018 (n = 230). Unadjusted and adjusted multivariable models were used to evaluate the impact of RA and other baseline patient and operative characteristics on inpatient opioid consumption and outpatient opioid demand. RESULTS Adjusted models demonstrated a small, significant increase in inpatient opioid consumption in patients with RA compared to no RA (4.7 estimated OE's without RA vs 6.2 OE's with RA from 24- to 48-h post-op, p < 0.05) but otherwise no significant differences at other timepoints (6.7 estimated OE's without RA vs 6.9 OE's with RA from 0- to 24-h post-op and 4.5 vs 4.4 from 48- to 72-h post-op, p > 0.05). Estimated cumulative outpatient opioid demand was significantly higher in patients with RA from discharge to 6 weeks and to 90 days (55.8 OE's without RA vs 63.9 with RA from discharge to 2 weeks, p > 0.05; 74.9 vs 95.1 OE's to 6 weeks, and 85 vs 113.1 OE's to 90 days, p < 0.05). DISCUSSION In distal femur fracture surgery, RA was associated with increased inpatient and outpatient opioid demand after adjusting for baseline patient and treatment characteristics. These results call into question the routine use of RA in distal femur fractures. LEVEL OF EVIDENCE Level III, retrospective, therapeutic cohort study.

HSS J 2022; 18:368-375. [PMID: 35846257 PMCID: PMC9247592 DOI: 10.1177/15563316211050884] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/21/2021] [Accepted: 05/19/2021] [Indexed: 02/07/2023]
Abstract
Background: Although total hip arthroplasty (THA) performed through the direct anterior (DA) approach is frequently marketed as superior to other approaches, there are concerns about increased risks of intraoperative and early postoperative femoral fracture. Purpose: We sought to assess patient-specific and radiographic risk factors for intraoperative and early postoperative (90-day) periprosthetic femoral fracture (PPFx) following DA approach THA. Methods: We retrospectively reviewed 1107 consecutive, primary, non-cemented DA THAs, performed between April 2009 and January 2015, for intraoperative and early postoperative PPFx. Patients lost to follow-up before 90 days (63), cemented or hybrid THA (52), or early femoral failure for another indication (3) were excluded, yielding 989 hips for analysis. Demographic variables and patient comorbidities were analyzed as risk factors for PPFx. Continuous variables were initially compared with 1-way analysis of variance (ANOVA) and categorical variables with chi-square test. A demographic matched-paired radiographic analysis was performed for femoral stem canal fill and compared using univariate logistic regression. Results: The incidence of perioperative PPFx was 2.02%, including 10 intraoperative and 10 early postoperative fractures. Sustaining a postoperative PPFx was associated with being 70 years old or older with a body mass index (BMI) of less than 25, or with having either osteoporosis or Parkinson disease. Radiographs demonstrated that intraoperative PPFx was associated with stems that filled greater proximally rather than distally. Conclusion: Our cohort study found older age, age over 70 with BMI of less than 25, osteoporosis, and Parkinson disease were associated with increased risk for early postoperative PPFx following DA approach THA. Intraoperative fractures may occur with disproportionate proximal femoral canal fill. Further study can evaluate whether cemented femoral components may mitigate risk in these patient populations.

Abstract
Surgical fixation of distal femur fractures in geriatric patients is an evolving topic. Unlike hip fractures, treatment strategies for distal femur fractures are ill-defined and lack substantive high-quality evidence. With an increasing incidence and an association with significant morbidity and mortality, it is essential to understand existing treatment options and their supporting evidence. Current fixation methods include the use of either retrograde intramedullary nails, or plate and screw constructs. Due to the variability in fracture patterns, the unique anatomy of the distal femur, and the presence or absence or pre-existing implants, decision-making as to which method to use can be challenging. Recent literature has sought to describe the advantages and disadvantages of each, however, there is currently no consensus on a standard of care, and little randomized evidence is available that directly compares intramedullary nails with plating. Future randomized studies comparing intramedullary nails with plating constructs are necessary in order to develop a standard of care based on injury characteristics.

Lower mortality in distal femoral fractures in the presence of a knee arthroplasty: an observational study on 2,725 fractures from the Swedish Fracture Register. Acta Orthop 2022; 93:684-688. [PMID: 35866693 PMCID: PMC9306289 DOI: 10.2340/17453674.2022.4376] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/13/2022] [Indexed: 01/31/2023] Open
Abstract
BACKGROUND AND PURPOSE Distal femoral fractures (DFF) in older patients have mortality rates comparable to fractures of the proximal femur. An ageing population combined with an increasing number of patients undergoing total knee arthroplasty (TKA) will make periprosthetic distal femoral fractures (pDFF) more common. We investigated whether a pre-existing TKA influences mortality rates. PATIENTS AND METHODS All patients ≥ 60 years registered in the Swedish Fracture Register with a DFF sustained between March 20, 2011 and December 31, 2020 were included. The study cohort comprised 2,725 patients, of which 650 had a pDFF. Unadjusted 90-day and 1-year mortality was estimated via Kaplan-Meier survival curves. A Cox regression model adjusted for age, sex, and treatment modality was used to investigate the association between DFF or pDFF and mortality. RESULTS Mean age was 80 years and 82% were females. The most common injury mechanism was a simple fall (75%). The pDFF and DFF group were similar with regards to age, sex, and trauma mechanism. Unadjusted 90-day and 1-year mortality was 11% (95% CI 10-12) and 21% (CI 19-23), respectively. Kaplan-Meier survival analysis demonstrated a slightly lower mortality for pDFFs, especially in patients ≤ 70 years. The Cox regression model showed a lower hazard ratio (HR) for mortality in the pDFF group (HR 0.82, CI 0.71-0.94). INTERPRETATION In a large cohort of patients ≥ 60 years with a distal femoral fracture, mortality rates at 90 days and 1 year post-injury were 11% and 21%, respectively. Periprosthetic fractures were associated with a lower mortality.

Abstract
Despite the rising prevalence of arthroplasty and aging population, limited data exist regarding differences in periprosthetic fracture clinical outcomes compared with native counterparts. This study compares differences in hospital treatment, morbidity, and mortality associated with periprosthetic distal femur fractures at an urban level 1 trauma center. We retrospectively reviewed all adult AO/OTA type 33 fractures (526) that presented to our institution between 2009 and 2018. In total, 54 native and 54 periprosthetic fractures were matched by age and gender. We recorded demographics, operative measures, length of stay (LOS), discharge disposition, and mortality. We used McNemar's and paired t-tests for analysis where appropriate (p < 0.05) (IBM SPSS Statistics for Windows, Version 26.0. Armonk, NY; IBM Corp.). The average age at injury was 74 years ± 12 (native) compared with 73 years ± 12 (periprosthetic). After 1:1 matching, the groups had similar body mass index (31.01 vs. 32.98, p = 0.966 for native and periprosthetic, respectively) and mechanisms of injury with 38 native and 44 periprosthetic (p = 0.198) fractures from low-energy falls. Both groups had 51/54 fractures managed with open reduction internal fixation with a locking plate. The remaining were managed via amputation or intramedullary nail fixation. Mean operative time (144 minutes (±64) vs. 132 minutes (±62), p = 0.96) and estimated blood loss (319 mL (±362) vs. 289 mL (±231), p = 0.44) were comparable between the native and periprosthetic groups, respectively. LOS: 9 days ± 7 (native) versus 7 days ± 5 (periprosthetic, p = 0.31); discharge disposition (to skilled nursing facility/rehab): n = 47 (native) versus n = 43 (periprosthetic, p = 0.61); and mortality: n = 6 (native) versus n = 8 (periprosthetic, p = 0.55). No significant differences were observed. We found no statistical differences in morbidity and mortality in periprosthetic distal femur fractures treated over 10 years at a level 1 trauma center. Native and periprosthetic AO/OTA type 33 distal femur fractures are serious injuries with similar outcomes at a level 1 trauma center.
