Is systematic deltoid ligament repair necessary in bimalleolar equivalent ankle fractures? A bi-centric case-control study.

Background: Bimalleolar equivalent fractures (BEF) represent a particularly challenging subset of ankle fractures, with ongoing debate among ankle surgeons about the necessity of systematic deltoid ligament repair. The present study aims to address this controversy by investigating the radiological and clinical outcomes of deltoid ligament repair in BEF compared to conservative management.

Hypothesis: Systematic deltoid ligament repair in BEF is not necessary.

Study of the release kinetics of dalbavancin from bone allografts.

Bone infections are common and difficult to treat, and secondary bone defects, which are often observed, may require a bone allograft. In this case, the surgeon will add antibiotics (usually vancomycin) in direct contact with the bone graft during the procedure, in order to allow in-situ release after implantation in the operating site. Dalbavancin is a novel antibiotic indicated for treating acute bacterial infections resistant to vancomycin.

Complications of open fractures: Observational study over 4 years, search for risk factors for infection.

Background: Open fractures account for approximately 2.6% of all fractures but continue to pose a significant clinical challenge due to their associated complications and potential impact on limb function. Among these complications, infection remains particularly prevalent.

A comparison of minimally invasive plate osteosynthesis (MIPO) versus open reduction and internal fixation (ORIF) in the management of tibial pilon fractures: A prospective randomized study.

Introduction: The aim of this study was to compare two surgical procedures for the treatment of tibial pilon fractures, i.e. minimally invasive plate osteosynthesis (MIPO) vs.

Is leg-length discrepancy after total hip arthroplasty corrected accurately after revision? : functional outcomes and complication rate in 57 patients.

Aims: The results of revision surgery to correct leg-length discrepancy (LLD) after total hip arthroplasty (THA) are not clear. Only two previous small series have been published dealing with this issue. The aim of this retrospective study of revision THAs for LLD was to determine the postoperative change in LLD, the functional outcomes, and whether obtaining equal leg lengths influenced function, as well as to report the complication rate and survival.

The influence of preoperative methylprednisolone bolus on edema in lower leg fractures: A prospective randomized controlled trial.

Introduction: Lower limb fractures are often associated with significant soft tissue damage, leading to edema and unfavorable conditions for wound healing. This study investigates the efficacy of a preoperative bolus of methylprednisolone (MP) in reducing edema and improving postoperative function in patients undergoing ankle or tibial fracture surgery.

Hypothesis: We hypothesized that the cohort receiving the steroid would experience faster edema reduction and improved functional outcomes.

What is the lower limb length discrepancy after arthroplasty for proximal femoral fracture? A prospective, multicenter observational study of 590 hips.

Introduction: Lower limb length discrepancy (LLD) following hip arthroplasty after proximal femoral fracture (PFFA) is little studied. The aim of this work was to answer the following questions: 1) What are the incidence and mean values ​​of LLD after PFFA? 2) What are the clinical consequences (tolerance) of LLD after PFFA? 3) Can we identify risk factors for LLD after PFFA? 4) Is there a significant difference in terms of LLD after PFFA to treat intra- versus extra-capsular fractures?

Hypothesis: LLD after proximal femoral fracture arthroplasty is rare but has good clinical tolerance, given the low functional demands of the patients.

Patients And Methods: This is a multicenter prospective observational cohort study (15 centers), including 590 patients, operated on for hip arthroplasty for proximal femur fracture between May 2022 and June 2023.

Can we trust the accuracy of the automatic calibration of the EOS system to measure lower limb length inequality after total hip arthroplasty? Comparison of EOS versus manual measurement on 110 calibrated radiographs.

Introduction: Traditionally, to determine a length on a limb radiograph after total hip arthroplasty (THA), calibration is performed manually with the diameter of a ball or the femoral head. More recently, the development of EOS with automatic calibration has called into question the usefulness of manual calibration to highlight lower limb length inequality (LLLI). However, the validation of EOS with automatic calibration without landmarks to measure length inequalities on large images has not been verified against manual measurements on calibrated radiographs (conventional method), which motivated the present work.

Do prospective randomized controlled trials comply with filed protocols? Spin study of 206 trials from 2010 to 2023.

Introduction: Prospective randomized controlled trials (RCT) have a robust methodology, but some distortions may occur during the course of study. Some protocols may not be available at the time an article is reading. Some authors may change the methodology between the time the protocol was submitted and when the trial results are actually published.

What is the clinical detection threshold for lower limb length inequality? In silico study of reproducibility and optimization using a centimeter graduated support.

Introduction: The threshold of a Leg Length Discrepancy (LLD) by clinical examination on a sheet or centimeter paper (CP) is not known precisely whether or not it concerns limbs equipped with a hip prosthesis. We therefore conducted a prospective in silico study in order to: (1) determine the reproducibility and sensitivity of the clinical measurement of the LLD in different ideal and "degraded" clinical situations, (2) determine the threshold from which the human eye is capable of detecting a length inequality in clinic, (3) to determine whether the use of a graduated support (centimeter paper) improves the clinical measurement threshold.

Hypothesis: Our hypothesis was that clinical measurement on a centimeter support would improve clinical measurement accuracy.

Functional outcomes and center of rotation restoration in total hip arthroplasty after acetabular fracture: A review of 367 hips.

Background: Total hip arthroplasty (THA) after acetabular fracture is typically performed months or years later for posttraumatic arthritis after initial conservative treatment. But THA can be performed earlier after open reduction and internal fixation (ORIF) of the fracture. The aim of this study was to determine which strategy is best.

Does a sign restricting operating room access reduce staff traffic in the surgical department?

Introduction: Infections following orthopedic surgery are rare but difficult to treat. Among the prevention measures reviewed during the Musculoskeletal Infection Society's (MSIS) 2023 international consensus meeting, the only strategy to obtain 100% agreement was the control of traffic in and out of the operating room (OR). Although this recommendation makes good sense, to our knowledge, it has not been previously investigated in a comparative study.

Unipolar Hip Hemiarthroplasty in Geriatric Patients: A Prospective Study and Analysis of Clinical and Radiological Outcomes.

Introduction: Femoral neck fractures (FNF) in the geriatric population are commonly treated with hip replacement procedures, such as total hip arthroplasty, unipolar hip hemiarthroplasty (UHA), and bipolar hip hemiarthroplasty (BHA). The optimal treatment remains controversial, considering outcomes and cost-effectiveness, with UHA often being cheaper. This prospective observational study aims to evaluate UHA's clinical and radiological outcomes, safety, and survivorship compared to existing literature.

Epidemiology of limb trauma interventions in France: Current state and future projections.

Context: The distributions and projections of trauma, treated according to the anatomical region, have not been studied in France. The objectives of this study were to obtain French epidemiological data specific to trauma procedures in orthopedic surgery, as well as to establish a statistical trend on the evolution of medical and surgical procedures resulting from this, since 2013 and over the years to come. Our hypothesis was that an increasing trend in trauma procedures since 2013 exists, with an epidemiological forecast of a continuing increase over 50 years, mainly in the context of the management of osteoporotic fractures related to the ageing French population.

Assessment and trends in the methodological quality of the top 50 most cited articles in shoulder arthroplasty.

Introduction: Shoulder arthroplasty is increasingly frequent, and the associated literature is abundant. Citation rate is often considered a good means of assessing impact and scientific value. However, analysis of methodological quality is also essential in evidence-based medicine.

Management of medial femorotibial osteoarthritis: Epidemiology, and survival of unicompartmental knee arthroplasty versus valgus high tibial osteotomy in France. Study of 108,007 cases from the French National Hospitals Database.

Introduction: Unicompartmental knee arthroplasty (UKA) and valgus high tibial osteotomy (HTO) are two options for isolated medial femorotibial osteoarthritis in genu varum. In the absence of registries for osteotomies and for arthroplasty in the knee, epidemiological data are hard to obtain in France. We therefore performed a retrospective study, with the aims of: 1) estimating UKA and HTO survival without revision by total knee arthroplasty (TKA), and 2) assessing risk factors for revision according to treatment group.

Growth progression of anterior cruciate ligament bone grafts in a pediatric population: magnetic resonance imaging analysis.

Background: In children, the incidence of anterior cruciate ligament (ACL) ruptures and reconstructions has significantly risen. Unfortunately, re-rupture rates following surgery are substantially higher in children than adults. Previous research suggests that smaller graft diameters are predictive of re-rupture.

Reasons for delays to orthopaedic and trauma surgery: A retrospective five-year cohort.

Background: Early surgery seeks to decrease peri-operative complication rates and mean hospital stay lengths while also improving patient satisfaction. Few data exist on optimising care before orthopaedic and trauma surgery (OTS), notably regarding delays to surgery after admission. The objective of this study was to identify reasons for OTS delays at a university-hospital OTS centre in France.

In vitro osteoblast activity is decreased by residues of chemicals used in the cleaning and viral inactivation process of bone allografts.

Allograft bone tissue has a long history of use. There are two main ways of preserving allografts: by cold (freezing), or at room temperature after an additional cleaning treatment using chemicals. These chemicals are considered potentially harmful to humans.

Orthopaedic and trauma surgery in France: Do patterns differ across healthcare institution types (public community, public university, private not-for-profit, and private for-profit)?

Background: No studies have evaluated, to our knowledge, potential differences in practices in France according to type of healthcare institution, i.e., university public hospital, community public hospital, or private hospital with or without participation in the public healthcare system.

Does metaphyseal modularity in femoral revision stems have a role in treating bone defects less severe than IIIB? Clinical and radiological results of a series of 163 modular femoral stems.

Introduction: Revision for loosening of femoral stems requires an extensive analysis of bone defects to determine the most appropriate course of action. The drawbacks of using modular stems are that they can break or corrode at their junction. They have rarely been evaluated based on the extent of bone loss and particularly in patients with less severe bone loss.

Results of slotted acetabular augmentation in adults with Crowe stage 1 and 2 hip dysplasia.

To determine the survival of slotted acetabular augmentation in adult dysplasia, we reviewed all cases operated on between 2002 and 2020 with clinical and radiological assessment and a 2.63 year minimum of follow-up. Twenty-three patients were included, with 91% of Crowe 1 hip dysplasia.
