BACKGROUND: Children with a tibial shaft fracture often present with valgus malalignment, even when anatomical reduction had been achieved at the fracture site. Pediatric bony structure has more elastic bones than that of adults, it can cause bowing deformity. Therefore, we evaluated pediatric tibial shaft fracture for the presence of bowing deformity, associated risk factors, and its clinical significance. HYPOTHESIS: There is an overlooked bowing deformity in pediatric tibial shaft fracture...

INTRODUCTION: The aim of this study was to investigate orthopaedic lower limb trauma patients' comprehension regarding the affected bone, the surgical implant used, and postoperative instructions, and to evaluate the relationship between sociodemographic features and health literacy. HYPOTHESIS: There is a relationship between health literacy levels, the medical awareness of orthopaedic trauma patients and sociodemographic characteristics. MATERIAL AND METHODS: The cross-sectional survey study was conducted from June to September 2021 in the orthopaedic clinic of a level 1 trauma centre...

Tibial bone defect remains a challenge in revision knee arthroplasty. The present innovative technique combines structural allograft and tantalum metaphyseal cone for treatment of AORI stage 2A and 2B (uncontained peripheral metaphyseal) tibial defect. The aim is to reconstitute bone stock and enhance allograft osseointegration, while limiting stress to the allograft by implanting the metaphyseal cone through the allograft and the original bone. Level of evidence: V (expert opinion).

OBJECTIVE: The current study was to perform an anatomical observation of the volar approach for wrist arthroscopy and to establish the safe zone for this approach. METHODS: Eight preserved specimens and 2 fresh specimens were used to simulate the medial-to-lateral operation and to mark the volar approach. Based on anatomical measurements of the volar approach, the closest distances from the 1/2, 6R, 6U, VR, VR' and VU approaches to the adjacent important structures were established...

INTRODUCTION: The aim of this study is to compare the preservation of bursal tissue and microfracture techniques and to examine the effectiveness of the combination of the two methods in rotator cuff tear healing in the rat shoulder. HYPOTHESIS: Bursal tissue preservation combined with microfracture is more effective in the rotator cuff repair. MATERIALS AND METHODS: Twenty-three Male Sprague-Dawley rats were randomly divided into two groups...

BACKGROUND: Follow-up care including rehabilitation therapy after isolated meniscal repair remains to be standardised. Thus, no standard criteria are available for the return to running (RTR) or return to sport (RTS). The objective of this study was to identify criteria for RTR and RTS after isolated meniscal repair, based on a review of the literature. HYPOTHESIS: Return-to-sport criteria after isolated meniscal repair have been published. METHODS: We performed a scoping review of the literature using the methodology developed by Arksey and O'Malley...

BACKGROUND: A mobile bearing can dislocate when joint laxity is larger than jumping height, the height difference between the bottom and the peak of the bearing (the highest point of the upper bearing surface on each side). Significant laxity due to improper gap balancing should therefore be avoided. However, once the bearing rotates vertically on the tibial component, the bearing can dislocate with smaller laxity than the jumping height. We mathematically calculated the required laxity for dislocation (RLD) and the required rotation of the bearing for dislocation (RRD)...

BACKGROUND: Routine laboratory studies are often performed following total hip arthroplasty (THA). However, lately, their necessity has been challenged and risk factors for postoperative transfusion are still debated. Recently a risk scoring system to single out patients that should have a postoperative blood test has been published by Wu et al. The purposes of this retrospective study were: 1) To validate this recently published risk scoring system to identify patients who should have a postoperative laboratory test, 2) to single out risk factors of postoperative transfusion, 3) to determine if another score can more accurately predict the need for postoperative transfusion...

INTRODUCTION: The use of minimally invasive cerclages at the tibia is not very common. First clinical results of a new operative technique published recently showed no increased complication rate. The aim of this anatomical study was to determine, if it is possible to introduce a minimally invasive cerclage at different levels of the tibia without encasing relevant nerves, vessels or tendons into the cerclage using this technique. HYPOTHESIS: The minimally invasive introduction of a cerclage at the tibia is possible without encasing relevant anatomical structures...

BACKGROUND: The optimal treatment for different types of displaced partial articular radial head fractures is still debatable. Fractures involving the articulating portion of the radial head can be defined also as bi-articular and are often underestimated. Moreover, the complete loss of periosteal contact between fracture fragments is a marker of instability. Available classifications do not emphasize these aspects. The purpose of the present study is to describe two assessment methods to identify fractures involving the articulating portion of the radial head and complete loss of periosteal contact with the help of 2D-3D CT scan...

INTRODUCTION: In France, prescribing pregabalin requires a secure prescription valid for 6 months since the decree of 12 February 2021, based on recommendations of the French Centre for Evaluation and Information on Pharmacodependence and Addiction vigilance (CEIP-A). This led to discontinuation of this treatment as a postoperative analgesic in the French ACL Study (FAST) cohort. We aimed to evaluate the impact of this change on early postoperative pain. HYPOTHESIS: Pregabalin is an important analgesic for reducing early postoperative pain after anterior cruciate ligament (ACL) repair...

Background One issue in total knee arthroplasty (TKA) is management of preoperative flexion contracture, which may be associated with poor functional outcome. Aim The aim of this study was to compare functional results in TKA with or without preoperative flexion contracture, treated according to a standardized algorithm of tissue release and bone cut. Patients and Method A single-center retrospective case-control study was performed on prospectively collected data for the period 1987-2016. Patients with >10° flexion contracture were assigned to the "contracture" group and associated to a selected control group at a ratio of 1:4...

BACKGROUND: In previous studies, good results have been reported after arthroscopic treatment of popliteal cysts and concomitant intra-articular pathology. However, only a few studies have reported the associated factors with residual popliteal cysts. The aim of this study was to examine the clinical and radiographic outcomes and investigate the factors associated with the recurrence of popliteal cyst after arthroscopic cyst decompression and cyst wall resection. HYPOTHESIS: The authors hypothesized that residual popliteal cyst after arthroscopic decompression and cystectomy would be associated with degenerative cartilage lesions...

BACKGROUND: Fractures to the fifth's metatarsal (MT-V) diaphysis are common. These are inconsistently referred to as diaphyseal-, shaft-, or Dancer's fractures. A comprehensive analysis of the MT-V fracture morphology is missing. The aim was to qualitatively and quantitatively analyze fracture patterns of MT-V diaphyseal fractures. HYPOTHESIS: Fractures to the shaft of the fifth metatarsal feature specific fracture morphologies. MATERIALS AND METHODS: Retrospective, radiologic database study...

Introduction Mediolateral shortening is a risk in treatment of clavicle shaft fracture., and can lead to scapular dyskinesis and shoulder dysfunction. Many studies advocated surgical treatment if shortening exceeds 15 mm. Hypothesis Clavicle shaft shortening of less than 15 mm has negative impact on shoulder function at more than 1 year's follow-up. Materials and methods A retrospective case-control comparative study was performed, with assessment by an independent observer. Clavicle length was measured on frontal radiographs showing both clavicles, and the ratio between the healthy and affected sides was calculated...

Introduction In patients who have hereditary multiple osteochondroma (HMO), progressive deformity of the forearm skeleton may lead to radial head dislocation. The latter is permanent, painful and causes weakness. Hypothesis There is a relationship between the amount of ulnar deformity and the presence of radial head dislocation in patients with HMO. Materials and Methods This was a cross-sectional radiographic study comprising an analysis of AP and lateral x-rays of 110 forearms in children having a mean age of 8 years and 4 months who were followed for HMO between 1961 and 2014...

INTRODUCTION: Lumbar discectomy is a frequent procedure performed by surgeons from specialties at risk of patient complaints. The objective of the study was to analyze the causes of litigations following lumbar discectomy to be able to reduce their frequency. MATERIAL AND METHODS: This observational, retrospective study was carried out at a French insurance company (Branchet). All files opened between the 1st of January 2003 and the 31st of December 2020, following lumbar discectomy without instrumentation and without any other associated code, undertaken by a surgeon insured by Branchet, were analyzed...

INTRODUCTION: The relationship between the occurrence of a periprosthetic hip or knee joint infection, a post-surgical hematoma and the time to surgical revision, along with the need to take samples for microbiology analysis has not been clearly defined. This led us to perform a retrospective study to 1) define the rate of infected hematoma and subsequent infection after surgical revision for hematoma and 2) analyze in which time frame the hematoma was likely to be infected. HYPOTHESIS: The more time elapsed before the postoperative hematoma is drained surgically after hip or knee replacement, the higher the hematoma infection rate and the late infection rate...
