Dislocation is one of the most common complications of total hip arthroplasty (THA). To the authors' knowledge, late recurrent dislocation of a THA with a ceramic-on-ceramic coupling secondary to fatigue fracture of the ceramic liner has never been described. A 76-year-old woman with right hip osteoarthritis underwent cementless modular THA with a ceramic-on-ceramic coupling. Approximately 10 y...

BACKGROUND Hip dislocation after arthroplasty for femoral neck fractures remains a serious complication. The aim of our study was to investigate the dislocation rate in acute femoral neck fracture patients operated with a posterior approach with cemented conventional or dual articulation acetabular components. METHODS We compared the dislocation rate in 56 consecutive patients operated with c...

There are situations which the tomographic exam is done on the affected hip or situations where the contralateral hip presents abnormalities that make it impossible to compare. In this study we aimed to evaluate a tomographic index that does not require comparison between the both hips. Twenty two patients with unilateral acetabular fracture dislocation with fracture of posterior wall were stud...

Avascular necrosis (AVN) of femoral head is a recognised complication of fracture dislocation of the hip joint but is not studied frequently in relation to acetabulum fractures. The aim was to establish the relationship between obturator externus and piriformis muscle morphology in acetabulum fractures and potenital development of AVN of the femoral head. Twenty-five fractures were included in ...

<p>Traumatic hip dislocation associated with an ipsilateral femoral fracture is a rare injury. It occurs in high-energy traumatic context. The classic mechanism consists of fall landing on the hip, which initially dislocates and femur secondarily by adduction proximal fragment. diagnosis difficult front whose signs mask vicious attitude dislocation. We reported case passenger motorcycle w...

OBJECTIVE To evaluate the efficacy of the use of retentive cup primary total hip replacement (THR) in high-dislocation risk subcapital fracture patients. METHODS During the years 2008 to 2012, 354 patients with displaced subcapital fracture were operated at our institute. The patients were selected to undergo primary constrained THR according to the following criteria: (1) a preinjury grade 4...

A 11 year old boy was brought to the accident and emergency department with a painful left hip after having been injured it in a tackle in a casual game of rugby. On examination the hip was found to be flexed, adducted and internally rotated with no distal neurovascular deficit. All movements of that hip were extremely painful. Posterior dislocation of hip was confirmed by radiograph (fig 1).Th...
