Project description:IntroductionThe British Orthopaedic Association Standards for Trauma and Orthopaedics (BOAST) guide the optimal management of open lower limb fractures. Adherence of the newly established Orthoplastic service at the Major Trauma Centre covering the Southeast of England was audited in relation to these standards.Materials and methodsAudit standards were produced. Data were collected using hospital records and the Trauma Audit and Research Network database. All open lower limb fractures managed between August 2020-August 2022 were included. Data collected included patient and injury demographics, and information related to initial and definitive management.ResultsOverall, 133 patients were identified, 70 men and 63 women, with an average age of 58 years. Women had a higher average age (69 years) and ASA grade (71% ASA 3 or higher). Low-energy injuries occurred in 69% of women compared to 78% of high-energy injuries in men (p<0.001). Among them, 108 (81%) were debrided within 24 h. The average time to first debridement was 18.78 h, and 95 (75%) were definitively closed within 72 h, 76 with primary closure, 7 with split-thickness skin graft, 7 with local flap and 36 with free flap. Overall, the post-operative infection rate was 13% with 94% of these fractures definitively closed within 72 h.ConclusionMost open lower limb fractures occurred in older women with higher ASA grade, from low-energy mechanisms. Most injuries were definitively managed as per the BOAST guidelines, but further efforts are required to improve the adherence to initial debridement targets, including training, appropriate resource allocation and implementation of procedures and proformas to guide injury management and improve documentation.

Project description:IntroductionIn April 2012 the John Radcliffe Hospital in Oxford became a major trauma centre (MTC). The British Orthopaedic Association and British Association of Plastic, Reconstructive and Aesthetic Surgeons joint standards for the management of open fractures of the lower limb (BOAST 4) require system-wide changes in referral practice that may be facilitated by the MTC and its associated major trauma network.MethodsFrom 2008 to 2013 a multistep audit of compliance with BOAST 4 was conducted to assess referral patterns, timing of surgery and outcomes (surgical site infection rates), to determine changes following local intervention and the establishment of the MTC.ResultsOver the study period, 50 patients had soft tissue cover for an open lower limb fracture and there was a significant increase in the proportion of patients receiving definitive fixation in our centre (p=0.036). The median time from injury to soft tissue cover fell from 6.0 days to 3.5 days (p=0.051) and the median time from definitive fixation to soft tissue cover fell from 5.0 days to 2.0 days (p=0.003). The deep infection rate fell from 27% to 8% (p=0.247). However, in 2013 many patients still experienced a delay of >72 hours between injury and soft tissue cover, primarily owing to a lack of capacity for providing soft tissue cover.ConclusionsOur experience may be relevant to other MTCs seeking to identify barriers to optimising the management of patients with these injuries.

Project description:BACKGROUND/OBJECTIVES:Limited studies suggest lower-extremity (LE) fractures are morbid events for nursing home (NH) residents. Our objective was to conduct a nationwide study comparing the incidence and resident characteristics associated with hip (proximal femur) vs nonhip LE (femoral shaft and tibia-fibula) fractures in the NH. DESIGN:Retrospective cohort study. SETTING:US NHs. PARTICIPANTS:We included all long-stay residents, aged 65 years or older, enrolled in Medicare from January 1, 2008, to December 31, 2009 (N = 1 257 279). Residents were followed from long-stay qualification until the first event of LE fracture, death, or end of follow-up (2 years). MEASUREMENTS:Fractures were classified using Medicare diagnostic and procedural codes. Function, cognition, and medical status were obtained from the Minimum Data Set prior to long-stay qualification. Incidence rates (IRs) were calculated as the total number of fractures divided by person-years. RESULTS:During 42 800 person-years of follow-up, 52 177 residents had an LE fracture (43 695 hip, 6001 femoral shaft, 2481 tibia-fibula). The unadjusted IRs of LE fractures were 1.32/1000 person-years (95% confidence interval [CI] = 1.27-1.38) for tibia-fibula, 3.20/1000 person-years (95% CI = 3.12-3.29) for femoral shaft, and 23.32/1000 person-years (95% CI = 23.11-23.54) for hip. As compared with hip fracture residents, non-hip LE fracture residents were more likely to be immobile (58.1% vs 18.4%), to be dependent in all activities of daily living (31.6% vs 10.8%), to be transferred mechanically (20.5% vs 4.4%), to be overweight (mean body mass index = 26.6 vs 24.0 kg/m2 ), and to have diabetes (34.8% vs 25.7%). CONCLUSIONS:Our findings that non-hip LE fractures often occur in severely functionally impaired residents suggest these fractures may have a different mechanism of injury than hip fractures. The resident differences in our study highlight the need for distinct prevention strategies for hip and non-hip LE fractures.

Project description:PurposeTo estimate the one-year sum of direct costs related to open lower limb fracture treatment in an academic setting in the Netherlands. The secondary objective was to estimate the impact of deep infection and nonunion on one-year total direct costs.MethodsA multi-center, retrospective cost analysis of open lower limb fractures treated in an academic setting in the Netherlands, between 1 January 2017 and 31 December 2018, was conducted. The costing methodology was based on patient level aggregation using a bottom-up approach. A multiple linear regression model was used to predict the total costs based on Fracture-related-infections, multitrauma, intensive care unit (ICU) admission, Gustilo-Anderson grade and nonunion.ResultsOverall, 70 fractures were included for analysis, the majority Gustilo-Anderson grade III fractures (57%). Median (IQR) one-year hospital costs were €31,258 (20,812-58,217). Costs were primarily attributed to the length of hospital stay (58%) and surgical procedures (30%). The median length of stay was 16 days, with an increase to 50 days in Fracture-related infections. Subsequent costs (46,075 [25,891-74,938] vs. 15,244 [8970-30,173]; p = 0.002), and total hospital costs (90,862 [52,868-125,004] vs. 29,297 [21,784-40,677]; p < 0.001) were significantly higher for infected cases. It was found that Fracture-related infection, multitrauma, and Gustilo-Anderson grade IIIA-C fractures were significant predictors of increased costs.ConclusionIn treatment of open lower limb fractures, deep infection, higher Gustilo-Anderson classification, and multitrauma significantly increase direct hospital costs. Considering the impact of infection on morbidity and total healthcare costs, future research should focus on preventing Fracture-related infections.

Project description:ObjectiveLower extremity amputation is often performed in patients where both lower extremities are at risk due to peripheral arterial disease or diabetes, yet the proportion of patients who progress to amputation of their contralateral limb is not well defined. We sought to determine the rate of subsequent amputation on both the ipsilateral and contralateral lower extremities following initial amputation.MethodsWe conducted a retrospective review of all patients undergoing lower extremity amputation (exclusive of trauma or tumor) at our institution from 1998 to 2010. We used International Classification of Diseases-Ninth Revision codes to identify patients and procedures as well as comorbidities. Outcomes included the proportion of patients at 1 and 5 years undergoing contralateral and ipsilateral major and minor amputation stratified by initial major vs minor amputation. Cox proportional hazards regression analysis was performed to determine predictors of major contralateral amputation.ResultsWe identified 1715 patients. Mean age was 67.2 years, 63% were male, 77% were diabetic, and 34% underwent an initial major amputation. After major amputation, 5.7% and 11.5% have a contralateral major amputation at 1 and 5 years, respectively. After minor amputation, 3.2% and 8.4% have a contralateral major amputation at 1 and 5 years while 10.5% and 14.2% have an ipsilateral major amputation at 1 and 5 years, respectively. Cox proportional hazards regression analysis revealed end-stage renal disease (hazard ratio [HR], 3.9; 95% confidence interval [CI], 2.3-6.5), chronic renal insufficiency (HR, 2.2; 95% CI, 1.5-3.3), atherosclerosis without diabetic neuropathy (HR, 2.9; 95% CI, 1.5-5.7), atherosclerosis with diabetic neuropathy (HR, 9.1; 95% CI, 3.7-22.5), and initial major amputation (HR, 1.8; 95% CI, 1.3-2.6) were independently predictive of subsequent contralateral major amputation.ConclusionsRates of contralateral limb amputation are high and predicted by renal disease, atherosclerosis, and atherosclerosis with diabetic neuropathy. Physicians and patients should be alert to the high risk of subsequent amputation in the contralateral leg. All patients, but particularly those at increased risk, should undergo close surveillance and counseling to help prevent subsequent amputations in their contralateral lower extremity.

Project description:Objective:To confirm the role of X-ray exposure in treating infected wound fractures at the lower limb and determine X-ray exposure times. Methods:Fifty-one wound swabs were collected from patients with infected open fractures at the lower limb with grade II, IIIA, B, and C according to the Gustilo and Anderson classification system and then cultured. The bacterial isolates were identified by biochemical tests and the VITEK-2 System and tested against several antibiotics. The X-ray exposure was done for open fractures by radiography (at kV133 and 5 milliambers). Results:The higher isolation rate was recorded for Staphylococcus aureus with 21 (41.2%) isolates, and most of them (20, 95.2%) were isolated from grade II fractures. The isolation rate of Gram-negative bacteria was 25.5% for Escherichia coli with 13 isolates, 19.6% for Pseudomonas aeruginosa with 10 isolates, and 13.7% for Klebsiella pneumoniae with 7 isolates, most of which were isolated from grade III fractures. The isolation rate of P. aeruginosa was 60% (6 isolates) from grade IIIA and 71.4% (5 isolates) from grade IIIB for K. pneumoniae, while for E. coli it was 69.2% (9 isolates) from grade IIIC. All the bacterial isolates recorded high levels of antibiotic resistance against most tested antibiotics. Wound cultures of grade II fractures appeared sterile after the first X-ray exposure, and these wounds were infected with S. aureus or P. aeruginosa. However, cultures of grade IIIA and IIIB fractures appeared sterile after the second X-ray exposure for all isolated bacteria, except for S. aureus (grade IIIA fractures) (after the third X-ray exposure). Grade IIIC fractures showed sterile culture after the third X-ray exposure for wounds infected with P. aeruginosa and E. coli. Conclusions:The study concluded that X-ray exposure showed high effectiveness in treating infected open fractures.

Project description:Lower limb fragility fractures require long-term rehabilitation and are also very expensive to treat. Clinically, early weight bearing and walking stability were reported as key measures of fracture restoration. This study introduces methods to numerically quantify these performance indices for a range of ankle and knee joint fractures. As a follow-up of initial treatment, experimental data was collected using force plates from 367 subjects divided into seven groups: ankle fracture (AF), lower leg ankle fracture (AL), calcaneus foot fracture (CF), knee tibia fracture (KF), knee patella fracture (KP), kneecap rupture (KR), and normal limb (NL). For each joint, data was analysed to evaluate intralimb and interlimb weight-bearing and walking stability for all fracture conditions. These thresholds were statistically compared with normal subjects. Some advantages of evaluating fracture restoration indices over the others include:•to quantify fracture restoration (weight-bearing, walking stability, and gait symmetry) using minimum setup and signal requirements.•to provide comprehensive tools to assess and overcome fracture-associated complications through a detailed preview of fractured limb functionality during subphases of a gait cycle.•in clinical research, such assessments are important as a reference to evaluate existing or new rehabilitative interventions.

Project description:Lower extremity open revascularization is a treatment option for peripheral artery disease that carries significant peri-operative risks; however, outcome prediction tools remain limited. Using machine learning (ML), we developed automated algorithms that predict 30-day outcomes following lower extremity open revascularization. The National Surgical Quality Improvement Program targeted vascular database was used to identify patients who underwent lower extremity open revascularization for chronic atherosclerotic disease between 2011 and 2021. Input features included 37 pre-operative demographic/clinical variables. The primary outcome was 30-day major adverse limb event (MALE; composite of untreated loss of patency, major reintervention, or major amputation) or death. Our data were split into training (70%) and test (30%) sets. Using tenfold cross-validation, we trained 6 ML models. Overall, 24,309 patients were included. The primary outcome of 30-day MALE or death occurred in 2349 (9.3%) patients. Our best performing prediction model was XGBoost, achieving an area under the receiver operating characteristic curve (95% CI) of 0.93 (0.92-0.94). The calibration plot showed good agreement between predicted and observed event probabilities with a Brier score of 0.08. Our ML algorithm has potential for important utility in guiding risk mitigation strategies for patients being considered for lower extremity open revascularization to improve outcomes.

Project description:Post traumatic lymphedema (PTL) is a known complication of extremity trauma that is detrimental to limb form and function, healing, and quality of life. In cases of complex lower extremity trauma with vascular and extensive soft tissue injury, the risk of PTL is increased. However, many trauma patients are lost to follow-up, making the risk and potential management of these patients' lymphedema difficult to characterize. The purpose of this report is to describe the successful surgical management of PTL secondary to significant lower extremity trauma requiring complex limb salvage reconstruction. A 43-year-old woman involved in a motorcycle accident presented with a Gustilo IIIB right tibial fracture and single-vessel leg. She underwent successful limb salvage with serial debridement, bony fixation, creation of an arteriovenous loop with a contralateral saphenous vein graft, and a chimeric latissimus dorsi-serratus anterior muscle flap. At the 5-month follow-up, she presented with significant right lower extremity lymphedema. She underwent lymphovenous bypass surgery guided by preoperative indocyanine green lymphography, which resulted in a 62% improvement in functional outcome measures, eliminated her prior need for compression garments and inability to wear regular shoes, and sustained improvement at two years follow-up. This case illustrates a near circumferential traumatic defect reconstructed with a muscle flap and successful delayed lymphatic reconstruction with lymphovenous bypass in the same patient.
