INTRODUCTION: Dislocation after total hip arthroplasty (THA) is a leading reason for surgical revision. The risk factors for dislocation are controversial, particularly those related to the patient and to the surgical procedure itself. The differences in opinion on the impact of these factors stem from the fact they are often evaluated using retrospective studies or in limited patient populations. This led us to carry out a prospective case-control study on a large population to determine: 1) the risk factors for dislocation after THA, 2) the features of these dislocations, and 3) the contribution of patient-related factors and surgery-related factors...

BACKGROUND: Proper reduction and stable fixation of articular fractures is essential for an early recovery and to avoid late complications. Arthroscopically assisted techniques for minimally invasive fixation have been introduced to reduce local morbidity and improve anatomic reduction of the fragments. However up to date no clear indications for surgery have been given. In addition, the precise rates of functional outcomes and complications are controversial. The hypothesis was the systematic analysis of the available literature would provide precise indications, outcomes and complications of arthroscopically assisted techniques for patellar fracture fixation...

BACKGROUND: Various factors contribute to instability of total hip arthroplasty (THA), with implant orientation being a major contributor. We performed a case-control study with computed tomography (CT) data to determine whether 1) orientation contributes to THA instability and 2) a safer target zone for stability than Lewinnek's classic safe zone can be defined. MATERIAL AND METHODS: We included prospectively 363 cases of THA dislocation that occurred during the calendar 2013 year in 24 participating hospitals...

BACKGROUND: Patellalowering aims to improve quadriceps function as a means of correcting crouch gait in patients with cerebral palsy (PC). Few studies have assessed the effects of patella lowering as a component of multilevel surgery. HYPOTHESIS: Including patella lowering into the components of multilevel surgery is beneficial in patients with crouch gait and patella alta. MATERIAL ET METHODS: In 12 lower limbs with patella alta (Caton-Deschamps index >1...

INTRODUCTION: The laminoplasty has been the most widely used surgical method for OPLL. In recent years, increasing attention has been drawn to the anterior operative approaches for surgical treatment of cervical OPLL. However, which method is the optimum selection for therapy of cervical OPLL is still obscure. Therefore, we performed this prospective nonrandomized clinical studyin patients with multilevelcervical myelopathydue to OPLL and compare thetherapeutic efficiencyof laminoplastyand anterior approach (cervical discectomy and/or cervicalcorpectomy) in the management of multi-level cervical OPLL...

INTRODUCTION: Both the overall shape of the calcaneus and anatomical reduction of joint congruity are important prognostic factors. However, there is a significant lack of biomechanical data supporting the clinical importance of calcaneus height, length and heel width. The objective of this study was to determine the effects of abnormal calcaneus morphology on ankle-hindfoot biomechanics. HYPOTHESIS: The normal biomechanics of the ankle-hindfoot would be severely disrupted by the abnormal calcaneus morphology...

BACKGROUND: Pilon variant posterior malleolar (PVPM) fractures significantly disrupt joint congruency and cause tibiotalar instability. They are often underestimated and inadequately treated. PURPOSE: This study assessed the outcomes of surgical treatment of this subtype of malleolar fracture, and examined the importance of computed tomography (CT) in diagnosis and surgical treatment. MATERIAL AND METHODS: CT images and radiographs of 67 patients with trimalleolar ankle fractures were retrospectively analyzed...

INTRODUCTION: When performing total hip arthroplasty (THA), it is important to maintain the femoral and acetabular offsets to ensure good joint stability and to restore the function of the hip abductor muscles. In our practice, we mainly use a lateralized stem and hollow out the acetabulum to the quadrilateral plate to accommodate a press-fit polyethylene cup. However, the repercussions of this preparation method, which is driven by the cup's design, are not known. We carried out a retrospective study to assess 1) the changes in the femoral and acetabular offset, 2) the height of the center of rotation, and 3) the repercussions on wear...

INTRODUCTION: Overuse, micro-traumas, and impingement, isolated or combined, are the more common etiological factors for rotator cuff tears. Metabolic disorders (diabetes, adiposity, hypercholesterolemia), hypertension, cigarette smoking and a genetic predisposition are considered risk factors. However, no study has compared the prevalence of these risk factors in subjects with bilateral and monolateral tears. HYPOTHESIS: Controlateral tears can be observed in patients with symptomatic monolateral rotator cuff lesions, especially in those with comorbidities...

BACKGROUND: The free vascularised fibular flap (FVFF) is widely used to treat bone defects, although it must be harvested from a healthy site. The objective of this study was to assess clinical morbidity and radiological changes at the FVFF donor site in children. HYPOTHESIS: Distal fibular stabilisation using a tibial strut decreases the prevalence of valgus ankle deformity. MATERIAL AND METHOD: 31 children managed at two centres between 1994 and 2014 were included...

BACKGROUND: Authors have recently proposed the concept of "hip-spine syndrome," however there exists limited evidence available to differentiate whether these concomitant arthritides are due to anatomic/structural causes, or systemic/metabolic effects. Exploring this relationship has important implications during the evaluation and treatment of both spine and hip disorders-a common clinical presentation of many patients. The purpose of this experiment was to investigate the individual contribution of hip arthritis towards the development of spine arthritis, with knee arthritis also being analyzed as a negative(systemic) control...

INTRODUCTION: The French Code of Public Health (CSP) does not explicitly require that patients be given a certain amount of time to think about a procedure, except for cosmetic surgery, where 15 days is required (Art. L 6322-2 CSP). We hypothesized that patients require a waiting period during their decision-making process for scheduled shoulder arthroscopy procedure. MATERIALS AND METHODS: This prospective observational study of 51 patients analysed the concept of a waiting period based on a 10-item questionnaire...

INTRODUCTION: Total hip arthroplasty (THA) requires bone reconstruction in case of severe acetabular injury, with risk of dislocation, especially postoperatively. Dual-mobility cups have proved effective in preventing dislocation in THA revision for instability, but their behavior when cemented in a metal reinforcement has been little studied. OBJECTIVES: The present study assessed results for a dual-mobility cup cemented in a metal reinforcement, in terms of aseptic loosening and postoperative instability...

BACKGROUND: The best method for stabilising supracondylar humeral fractures (SHFs) in children remains unclear. The objective of this study was to compare the outcomes of five different fixation methods for SHFs in children. HYPOTHESIS: Differences in intra-operative and short-term post-operative parameters can be demonstrated across different fixation methods for SHFs in children. PATIENTS AND METHODS: We reviewed the medical files of paediatric patientsmanaged at our centre between 2006 and 2016 for SHFwith major displacement (type 3 or4 in the Lagrange-Rigault classification)...

The treatment for non-displaced (< 2 mm displacement) fractures of the lateral humeral condyle in children is controversial. Most studies recommend non-surgical treatment. However, plain radiographs are not sufficient to evaluate extension of the fracture line through the articular cartilage. This explains the high frequency of secondary displacements and non-unions, despite well-conducted conservative treatment. We hypothesized that MRI could be used to analyse whether the fracture is complete or incomplete...

Orthopedic surgeons are often consulted for diagnosis of MASS (mitral valve prolapse, aortic enlargement, skin and skeletal findings) syndrome, imaging showing periarticular calcification, or joint stiffness. Such presentations in a dialyzed patient should suggest tumoral calcinosis, which is a rare complication of dialysis, often diagnosed wrongly or late. It is often associated with calcium phosphate balance disorder, in which treatment is difficult and must take account of known contributing factors: severe hyperparathyroidism, increased phosphocalcic product, therapeutic calcium and vitamin D overload, and bone turnover slowed for varying reasons...
