Comparison of the effect of combined usage of povidone-iodine irrigation and topical vancomycin powder to the use of povidone-iodine irrigation alone on the periprosthetic joint infection incidence rate in patients undergoing primary total hip and knee arthroplasty: a protocol for multicenter prospective randomized clinical trial.

BACKGROUND: With the increasing number of joint replacement surgeries, periprosthetic joint infection (PJI) has become a significant concern in orthopedic practice, making research on PJI prevention paramount. Therefore, the study will aim to compare the effect of combined usage of povidone-iodine and topical vancomycin powder to the use of povidone-iodine alone on the PJI incidence rate in patients undergoing primary total hip (THA) and total knee arthroplasty (TKA). METHODS: The prospective randomized clinical trial will be conducted in two independent voivodeship hospitals with extensive experience in lower limb arthroplasties. The studied material will comprise 840 patients referred to hospitals for primary THA or TKA. The patients will be randomly allocated to two equal groups, receiving two different interventions during joint replacement. In group I, povidone-iodine irrigation and consecutively topical vancomycin powder will be used before wound closure. In group II, only povidone-iodine lavage irrigation will be used before wound closure. The primary outcome will be the incidence rate of PJI based on the number of patients with PJI occurrence within 90 days after arthroplasty. The occurrence will be determined using a combined approach, including reviewing hospital records for readmissions and follow-up phone interviews with patients. The infection will be diagnosed based on Musculoskeletal Infection Society criteria. The chi-square test will be used to compare the infection rates between the two studied groups. Risk and odds ratios for the between-groups comparison purposes will also be estimated. Medical cost analysis will also be performed. DISCUSSION: A randomized clinical trial comparing the effect of combined usage of povidone-iodine irrigation and vancomycin powder to the use of povidone-iodine irrigation alone in preventing PJIs after primary arthroplasty is crucial to advancing knowledge in orthopedic surgery, improving patient outcomes, and guiding evidence-based clinical practices.

Diagnostic Value of Neutrophil-Lymphocyte Ratio in Predicting Post-Operative Infection after Orthopedic Surgery: A Systematic Review and Meta-Analysis.

Objective: This study aims to evaluate the predictive value of neutrophil-lymphocyte ratio (NLR) in determining infection after orthopedic surgery. Methods: A comprehensive search was conducted in PubMed, EBASE, CNKI, and Wanfang databases to identify relevant studies. The quality of the included studies was assessed using QUADAS-2. Data extraction was performed to calculate sensitivity, specificity, and other indicators. Bivariate mixed-effects meta-analysis was conducted using Stata software. The sources of heterogeneity were evaluated, and a summary receiver operating characteristic curve was generated. Results: A total of 16 literatures comprising 18 studies involving 3737 patients were included in this analysis. NLR demonstrated moderate sensitivity (0.77) and specificity (0.69) in diagnosing orthopedic post-operative infection, with an area under the curve of 0.80 and diagnostic odds ratio of 7.76. Significant heterogeneity was observed among the studies, primarily due to variations in surgical type, infection type, blood test timing, and NLR cutoff value. Fagan nomogram indicated that NLR could increase the positive posterior probability to 72% and decrease the negative posterior probability to 25%. The pooled effect of the likelihood ratio dot plot for diagnosis fell in the lower right quadrant. Deek funnel plot suggested no publication bias in this study. Conclusion: NLR holds certain value in diagnosing infection after orthopedic surgery and can provide additional information to assess the risk of infection. However, its predictive performance is influenced by various factors, and it cannot be used as a sole criterion for confirming the diagnosis. Prospective studies should be conducted in the future to optimize the diagnostic threshold and explore its combination with other indicators.

A Systematic Review of Human Amnion Enhanced Cartilage Regeneration in Full-Thickness Cartilage Defects.

Cartilage defects present a significant challenge in orthopedic medicine, often leading to pain and functional impairment. To address this, human amnion, a naturally derived biomaterial, has gained attention for its potential in enhancing cartilage regeneration. This systematic review aims to evaluate the efficacy of human amnion in enhancing cartilage regeneration for full-thickness cartilage defects. An electronic search was conducted on MEDLINE-PubMed, Web of Science (WoS), and the Scopus database up to 27 December 2023 from 2007. A total of 401 articles were identified. After removing 125 duplicates and excluding 271 articles based on predetermined criteria, only 5 articles remained eligible for inclusion in this systematic review. All five eligible articles conducted in vivo studies utilizing rabbits as subjects. Furthermore, analysis of the literature reveals an increasing trend in the frequency of utilizing human amnion for the treatment of cartilage defects. Various forms of human amnion were utilized either alone or seeded with cells prior to implantation. Histological assessments and macroscopic observations indicated usage of human amnion improved cartilage repair outcomes. All studies highlighted the positive results despite using different forms of amnion tissues. This systematic review underscores the promising role of human amnion as a viable option for enhancing cartilage regeneration in full-thickness cartilage defects, thus offering valuable insights for future research and clinical applications in orthopedic tissue engineering.

A rare variation in popliteal artery branching: anterior tibial artery and fibular artery from the common tibiofibular trunk.

The popliteal artery is a continuation of the femoral artery and is the main arterial supply to the lower leg and foot. Variation in the branching of the popliteal artery typically occurs proximal or distal to where the vessel crosses the popliteus muscle. In the case of a routine dissection of a 92-year-old female cadaver, a variation of the popliteal artery was found where the branches are a posterior tibial artery and a common tibiofibular trunk. It is important to recognize the vascular variations that exist in the popliteal fossa to prevent any unforeseen complications during surgeries or procedures to the knee or lower leg.

Investigation and Management of Lower Limb Septic Arthritis in Children: An Update Using the Latest British Orthopaedic Association Standard for Trauma (BOAST) Guidelines.

Septic arthritis is a serious condition in children, with the hip and knee joints most typically affected. Patients typically present with pain, joint swelling, fever, and an inability to bear weight. Early recognition and treatment are crucial, as untreated septic arthritis can lead to serious complications, including sepsis, irreversible joint damage, growth problems, and early-onset arthritis. Clinical signs, inflammatory markers, and imaging are used for the diagnosis of septic arthritis. The mainstay of management includes antibiotic therapy and surgical washout. Long-term follow-up is essential to monitor for complications.

Evaluation of Community Involvement and Development in an Orthopedic Hospital.

Improving healthcare requires appropriate community involvement supported by appropriate partner engagement methods. This research aims to develop a complex tool for evaluating the social responsibility of health facilities regarding community involvement and development. We developed areas of a new reference framework for the sustainability of healthcare organizations, which includes the area of community involvement and expansion. It is made up of nine indicators. These were designed using the most representative activities reported by hospitals around the world. Their testing was conducted in an orthopedic emergency hospital. The designed indicators are community engagement actions; the interventions' content adapted to the community; partnership and networking; the involvement of volunteers and training networks; the involvement and participation of professional associations; community-involved local opinion leaders; satisfaction with partnerships; initiatives together with the community; and educational visits. The testing and validation of health practices of the indicators highlighted their adequacy with the proposed purpose of the research and the promotion of sustainable development. We have also verified their compatibility with the requirements of national hospital accreditation legislation and the European framework for quality assurance in hospitals.

The Relevance of Implanted Percutaneous Electrical Nerve Stimulation in Orthopedics Surgery: A Systematic Review.

Background: Percutaneous peripheral nerve stimulation (PNS) is a form of neuromodulation that involves the transmission of electrical energy via metal contacts known as leads or electrodes. PNS has gained popularity in orthopedic surgery as several studies have supported its use as a pain control device for patients suffering from pain due to orthopedic pathologies involving the knee, shoulder, and foot. The purpose of this systematic review is to summarize the literature involving peripheral nerve stimulation in orthopedic surgery. The existing body of literature provides support for further research regarding the use of PNS in the management of knee pain, hip pain, shoulder pain, foot pain, and orthopedic trauma. Notably, the evidence for its efficacy in addressing knee and shoulder pain is present. Methods: This study was conducted following PRISMA guidelines. Seven hundred and forty-five unique entries were identified. Two blinded reviewers assessed each article by title and abstract to determine its relevance and categorized them as "include", "exclude", and "maybe". After a preliminary review was completed, reviewers were unblinded and a third reviewer retrieved articles labeled as "maybe" and those with conflicting labels to determine their relevance. Twenty-eight articles were included, and seven hundred and seventeen articles were excluded. Articles discussing the use of PNS in the field of orthopedic surgery in patients > 18 years of age after 2010 were included. Exclusion criteria included neuropathic pain, phantom limb pain, amputation, non-musculoskeletal related pathology, non-orthopedic surgery related pathology, spinal cord stimulator, no reported outcomes, review articles, abstracts only, non-human subjects. Results: A total of 16 studies analyzing 69 patients were included. All studies were either case series or case reports. Most articles involved the application of PNS in the knee (8) and shoulder (6) joint. Few articles discussed its application in the foot and orthopedic trauma. All studies demonstrated that PNS was effective in reducing pain. Discussion: Peripheral nerve stimulation can be effective in managing postoperative or chronic pain in patients suffering from orthopedic pathology. This systematic review is limited by the scarcity of robust studies with substantial sample sizes and extended follow up periods in the existing literature.

Impact of delayed presentation and surgical management on radiologic and clinical outcomes of pediatric septic hip.

Background: Septic arthritis of the hip joint (septic hip) is the bacterial infection of the hip. Delayed treatment increases the risk of extensive joint damage, systemic infection, prolonged recovery, higher healthcare costs, and long-term disability. This study explores the repercussions of delayed surgical treatment in pediatric septic hip. Methods: In this observational study, pediatric patients diagnosed with septic hip between 2012 and 2021 were retrospectively selected from a major referral center in Shiraz, Iran. We collected clinical and radiological data, including Kocher score and determined Choi classification in follow-up radiographs. Multivariate logistic regression analysis was used to assess the impact of delay to surgery on the development of clinical sequelae and radiological deformities in the presence of potential confounders of age and Kocher criteria. Results: Out of 49 children with delayed presentation, 46 survived and entered the study. Mean delay from symptom presentation to admission was 12.67 ± 10.51 days, and mean delay from admission to surgery was 5.33 ± 6.47 days. Of the 46 patients, 28.26% developed clinical sequelae. The Choi classification revealed that 54.35% of patients developed no residual deformity. A multivariate logistic regression analysis indicated a statistically significant association between delay to surgery and the development of radiological deformities (adjusted odds ratio: 1.36, 95% CI: 1.14-1.64, p = 0.001). Additionally, a separate analysis revealed that each additional day of delay was associated with a 12% increase in the odds of clinical sequelae (adjusted odds ratio: 1.12, 95% CI: 1.03-1.22, p = 0.006). Sensitivity analyses confirmed the relationship of delay from admission to surgery in developing both outcomes. Conclusion: Delay in medical care and surgical management remains the most important factor affecting the outcomes of septic hip. The study underscores the critical role of timely surgical intervention in reducing complications in pediatric septic hip patients.

Analysis of the diversity pipeline for the orthopedic trauma surgeon workforce in the United States.

INTRODUCTION: There is a lack of research on the state of racial, ethnic, and gender diversity in the emerging orthopedic trauma workforce. The purpose of this study was to analyze the training pathway for diverse candidates in orthopedic trauma as it relates to race, ethnicity, and sex. METHODS: Self-reported demographic data were compared among allopathic medical students, orthopedic surgery residents, orthopedic trauma fellows, and the general population in the United States (2013-2022). Race categories consisted of White, Asian, Black, and Native American/Alaskan Native (NA/AN), and Native Hawaiian/Pacific Islander (NH/PI). Ethnicity categories were Hispanic/Latino or non-Hispanic/Latino. Sex categories were male and female. Representation was calculated at each stage of accredited training. Participation-to-prevalence ratios (PPRs) quantified the equitable representation of demographic groups in the emerging orthopedic trauma workforce relative to the US population. PPR thresholds were used to classify representation as overrepresented (PPR > 1.2), equitable (PPR = 0.8-1.2), and underrepresented (PPR < 0.8). RESULTS: Relative to medical school and orthopedic surgery residency, fewer female (48.5 % vs 16.7 % vs 18.7 %, P < 0.001), Hispanic (6.1 % vs 4.5 % vs 2.6 %, P < 0.001), Black (6.9 % vs 5.0 % vs 3.1 %, P < 0.001), and Asian (24.0 % vs 14.3 % vs 12.2 %, P < 0.001) trainees existed in orthopedic trauma fellowship training. In contrast, more male (51.5 % vs 83.3 % vs 81.3 %, P < 0.001) and White (62.8 % vs 79.1 % vs 84.0 %, P < 0.001) trainees existed in orthopedic trauma fellowship relative to earlier training stages. There were zero NA/AN or NH/PI trainees in orthopedic trauma (PPR = 0). Relative to the US population, Hispanic (PPR = 0.14), Black (PPR = 0.25), and female (PPR = 0.37) trainees were underrepresented in orthopedic trauma. In contrast, Asian (PPR = 2.04), male (PPR = 1.64), and White (PPR = 1.36) trainees were overrepresented in orthopedic trauma. CONCLUSION: Women, racial, and ethnic minorities are underrepresented in the emerging orthopedic trauma workforce relative to the US population, and earlier stages of training. Targeted recruitment and guided mentorship of these groups may lead to greater interest, engagement, and diversity in orthopedic trauma.

Establishing surgical volume benchmarks for Orthopaedic Trauma Association (OTA)-accredited fellowship training.

INTRODUCTION: Case volumes of trauma centers and surgeons influence clinical outcomes following orthopaedic trauma surgery. This study quantifies surgical volume benchmarks for Orthopaedic Trauma Association (OTA)-accredited fellowship training in the United States. METHODS: This was a retrospective cross-sectional study of orthopaedic trauma fellows graduating between 2018 and 2019 to 2022-2023. Case volume percentiles were calculated across categories and variability defined as the fold-difference between 90th and 10th percentiles. Temporal trends were assessed with linear regression. RESULTS: 446 orthopaedic trauma fellows were included in this study. Mean reported case volume increased from 898 ± 245 in 2018-2019 to 974 ± 329 in 2022-2023 (P = 0.066). Mean case volume was 924 over the study period and mostly consisted of other (418 cases, 45 %), subtrochanteric/intertrochanteric femoral neck (84 cases, 9 %), open fracture debridement (72 cases, 8 %), pelvic ring disruption / fracture (55 cases, 6 %), acetabular fracture (41 cases, 4 %), tibial shaft fracture (39 cases, 4 %), and femoral shaft fracture (38 cases, 4 %) cases. Overall variability in total reported case volume was 2.0. Variability was greatest in distal radius fracture (14.8), amputation (9.5), fasciotomy (8.0), and proximal humerus repair (5.0). CONCLUSION: Graduates from OTA-accredited fellowship training perform 924 cases on average, which exceeds the current minimum requirement of 600 cases. Case volume benchmarks can assist trainees and faculty align training goals with fellowship program strengths. More research is needed to determine evidence-based case minimum requirements for core competency training in orthopaedic trauma surgery.

Six-Degree-of-Freedom Freehand 3D Ultrasound: A Low-Cost Computer Vision-Based Approach for Orthopedic Applications.

In orthopedics, X-rays and computed tomography (CT) scans play pivotal roles in diagnosing and treating bone pathologies. Machine bulkiness and the emission of ionizing radiation remain the main problems associated with these techniques. The accessibility and low risks related to ultrasound handling make it a popular 2D imaging method. Indeed, 3D ultrasound assembles 2D slices into a 3D volume. This study aimed to implement a probe-tracking method for 6 DoF 3D ultrasound. The proposed method involves a dodecahedron with ArUco markers attached, enabling computer vision tracking of the ultrasound probe's position and orientation. The algorithm focuses on the data acquisition phase but covers the basic reconstruction required for data generation and analysis. In the best case, the analysis revealed an average error norm of 2.858 mm with a standard deviation norm of 5.534 mm compared to an infrared optical tracking system used as a reference. This study demonstrates the feasibility of performing volumetric imaging without ionizing radiation or bulky systems. This marker-based approach shows promise for enhancing orthopedic imaging, providing a more accessible imaging modality for helping clinicians to diagnose pathologies regarding complex joints, such as the shoulder, replacing standard infrared tracking systems known to suffer from marker occlusion problems.

Post-Arthroplasty Spatiotemporal Gait Parameters in Patients with Hip Osteoarthritis or Developmental Dysplasia of the Hip: An Observational Study.

Total hip arthroplasty (THA) is a preferred treatment for primary osteoarthritis (OA) or secondary degenerative arthropathy due to developmental hip dysplasia (DDH). Gait analysis is considered a gold standard for evaluating post-arthroplasty walking patterns. This study compared post-THA spatiotemporal gait parameters (SGPs) between OA and DDH patients and explored correlations with demographic and clinical variables. Thirty patients (15 per group) were recorded during gait and their SGPs were analyzed. Functionality was evaluated with the Oxford Hip Score (OHS). The OA patients were significantly older than DDH patients (p < 0.005). Significant and moderate to strong were the correlations between SGPs, age, and four items of the OHS concerning hip pain and activities of daily life (0.31 < Pearson's r < 0.51 all p < 0.05). Following THA, both groups exhibited similar levels of the examined gait parameters. Post-arthroplasty SGPs and OHS correlations indicate limitations in certain activities. Given the absence of pre-operative data and the correlation between age and SGPs and OHS, ANCOVA testing revealed that age adjusts OHS and SGP values, while pre-operative diagnosis has no main effect. These findings indicate that hip OA or DDH do not affect postoperative SGPs and patients' functionality. Future studies should examine both kinematic and kinetic data to better evaluate the post-THA gait patterns of OA and DDH patients.

Identification of osteoblastic autophagy-related genes for predicting diagnostic markers in osteoarthritis.

The development of osteoarthritis (OA) involves subchondral bone lesions, but the role of osteoblastic autophagy-related genes (ARGs) in osteoarthritis is unclear. Through integrated analysis of single-cell dataset, Bulk RNA dataset, and 367 ARGs extracted from GeneCards, 40 ARGs were found. By employing multiple machine learning algorithms and PPI networks, three key genes (DDIT3, JUN, and VEGFA) were identified. Then the RF model constructed from these genes indicated great potential as a diagnostic tool. Furthermore, the model's effectiveness in predicting OA has been confirmed through external validation datasets. Moreover, the expression of ARGs was examined in osteoblasts subject to excessive mechanical stress, human and mouse tissues. Finally, the role of ARGs in OA was confirmed through co-culturing explants and osteoblasts. Thus, osteoblastic ARGs could be crucial in OA development, providing potential diagnostic and treatment strategies.

Physician Workforce in Kansas: Where are the Orthopedic Surgeons?

Introduction: Rural patients have greater need but less access to orthopedic surgical care than their urban counterparts. Previous studies have investigated rural surgical care, but this is the first to assess the Kansas orthopedic surgery workforce to identify changes over time and rurality and inform thinking about future workforce composition. Methods: The authors analyzed 2009 and 2019 AMA MasterFile and Area Health Resource File (AHRF) data. Using frequencies, percentages, and calculations of orthopedic surgeons per capita, we assessed workforce changes by rurality (Rural Urban Continuum Codes). Results: The dataset included 307 orthopedic surgeons; 197 were in both 2009 and 2019. Of these, 165 were in active practice in 2009 and 244 in 2019, an increase of 79 (47.9%). Kansas had smaller proportions of surgeons in rural (non-metro) versus urban (metro) counties in both years. Orthopedic surgeons per capita grew throughout the state, but the increase was smaller in rural counties. There were 11 women orthopedic surgeons in both years, 3.6% of the total 307. Among the 197 surgeons in both years, four (2.0%) were women. No women orthopedic surgeons were in non-metro counties either year. Conclusions: Although the Kansas orthopedic surgery workforce grew from 2009 to 2019, rural Kansas remains a surgery desert based on orthopedic surgeons per capita. Further studies could determine whether this trend is similar to that in other rural states and how to attract orthopedic surgeons to rural practice.

Three-Headed Biceps Brachii Muscle: A Rare Site of Proximal Median Nerve Entrapment.

The biceps brachii muscle is a highly variable muscle in the anterior compartment of the arm, and the most common variants include additional heads or slips. The median nerve courses with the brachial artery in the medial arm near the biceps brachii muscle, crosses the elbow, and enters the forearm deep to the bicipital aponeurosis. While entrapment of the median nerve in the carpal tunnel is one of the most common neuropathies, more proximal entrapments by the bicipital aponeurosis or other variants have been reported. In a 94-year-old embalmed female cadaver received through the Humanity Gift Registry of Pennsylvania, a biceps brachii muscle with an additional slip that arose from the coracoid process was found, which bridged over the median nerve and blended with the investing fascia of the forearm flexors via aponeurosis. Because of the course of this muscular slip in the arm and its relationship to the median nerve, this may be an additional site of proximal entrapment of the median nerve. It is important to consider these rare sites of nerve entrapment when diagnosing patients with median nerve neuropathy.

Gait analysis of patients undergoing knee endoprosthesis: functional differences between tibia and femur resections.

With the improvement in survival of patients undergoing knee reconstructive surgeries, the functional parameter became widely studied heading optimize and minimize motor sequelae. In patients undergoing knee endoprosthesis, proximal tibial or distal femoral resections affect the functioning of the knee extensor mechanism, with possible repercussions on gait. Seventeen patients were selected, divided into two groups, undergoing distal femoral or proximal tibial resection, and gait analysis examination was performed. Changes in gait velocity, cadence, step length, and alterations in the support and balance phase were observed. No major statistically significant differences were found in the kinetic and kinematic parameters between the operated groups. The study corroborates that although tibial resections have a higher theoretical risk of compromising the extensor mechanism, such data were not observed in the analyzed sample.

Incidence of Upper Extremity Neuropathies at a Single Tertiary Care Institution in the United States: Trends in Recent Years, Including the COVID-19 Pandemic.

OBJECTIVE: This study examined trends in upper extremity (UE) neuropathies at a large urban tertiary care center in the Northeastern United States over the past five years, including the period of the COVID-19 pandemic. METHOD: A retrospective medical record review was conducted from 2018 to 2022. We collected data from unique patient records identified using International Classification of Diseases, Tenth Revision (ICD-10) codes for UE neuropathies. We characterized subjects by age, demographics, and duration of symptoms.  Results: This study included 288 pediatric patients and 51,997 adult patients newly diagnosed with UE neuropathy. Most patients were aged 55+; 0.4% of all patients diagnosed with UE neuropathy were children. Across all ages, there was an overall increase in UE neuropathy diagnoses in the past five years, with the most noticeable increases from 2018 to 2019 (+5,761 diagnosed individuals, or +122%) and from 2020 to 2021 (+2,769 diagnosed individuals, or +28.8%). CONCLUSION: Our institution's UE neuropathy diagnoses have increased in the past five years. Of note, there was a significantly increased rate of UE neuropathy diagnoses from 2020 to 2021. This increase coincides with the COVID-19 pandemic, which is leading to a changing environment for many Americans. These societal changes will likely become indelible after the pandemic; safety practices should be enacted to avoid these debilitating neuropathies.

Diet influences knee osteoarthritis osteophyte formation via gut microbiota and serum metabolites.

Osteophyte formation, a key indicator of osteoarthritis (OA) severity, remains poorly understood in its relation to gut microbiota and metabolites in knee osteoarthritis (KOA). We conducted 16S rDNA sequencing and untargeted metabolomics on fecal and serum samples from 20 healthy volunteers, 80 KOA patients in Guangdong, and 100 in Inner Mongolia, respectively. Through bioinformatics analysis, we identified 3 genera and 5 serum metabolites associated with KOA osteophyte formation. Blautia abundance negatively correlated with meat, cheese, and bean consumption. The 5 serum metabolites negatively correlated with dairy, beef, cheese, sugar, and salt intake, yet positively with age and oil consumption. Higher Blautia levels in the gut may contribute to KOA osteophyte formation, with serum metabolites LTB4 and PGD2 potentially serving as biomarkers. KOA patients in Inner Mongolia exhibited lower Blautia levels and reduced expression of 5 serum metabolites, possibly due to cheese consumption habits, resulting in less osteophyte formation.

Comparing clinical outcomes of patients with severe lower limb trauma undergoing orthoplastic and orthopedic surgeries: A long-term study protocol.

This long-term study protocol aims to compare the clinical outcomes of patients with severe lower limb trauma undergoing orthoplastic and orthopedic surgeries, focusing on their physical and psychological status. Patients with lower limb injuries and open fractures have been recruited since October 2019 and will be followed up until October 2024. The patients will be divided into two groups: (1) Orthoplastic group, where single-stage debridement, fixation, and soft tissue repair will be performed, and (2) Orthopedic group, where soft tissue repair will be done in a delayed-stage. The follow-up period will be one year, during which clinical data, limb function recovery, psychological scores, and health-related quality of life (HRQOL) will be evaluated to assess postoperative recovery and clinical outcomes. Additional clinical data, such as socio-demographic information, baseline features, Enneking score, Visual Analogue Scale (VAS) score, two-point discrimination score, and blood test parameters will also be collected. The 36-Item Short Form Health Survey (SF-36) will be used to evaluate HRQOL, while the Post-traumatic Stress Disorder Checklist (PCL) will assess the severity of self-reported post-traumatic stress disorder. The results of this study will provide valuable insights into prognostically relevant targets and contribute to improving the management and outcomes of patients with lower limb injuries and open fractures, who often face challenges related to limb disability and potential amputation postoperatively, significantly impacting their psychological and physical well-being.
