One of the most common causes for revision surgery following total hip arthroplasty (THA) is dislocation.Dislocation is associated with a considerable amount of suffering and risks for the patient, and extra costs for the health care system.Compared with degenerative arthritis, the dislocation rate is doubled for avascular necrosis and multiplied by three times for congenital dislocation, four ...

Two patients are described, each with a fracture-dislocation of the hip combined with a fracture of the neck of the same femur. Open reduction combined with internal fixation was performed in both cases. Eight years later one patient had developed avascular necrosis of the femoral head; no signs of avascular necrosis or associated arthritis have appeared in the other patient after four years. A...

When fracture of the femoral shaft and dislocation of the hip occur in the same limb the dislocation is often missed. In this paper we offer a way to avoid this diagnostic pitfall. It has been estimated that combined femoral shaft fracture and hip dislocation occur once in every 100,000 cases of fracture (Wiltberger, Mitchell and Hedrick 1948). In a century and a half a total of eighty-one such...

Highly cross-linked polyethylene liners are widely used in total hip arthroplasty because they experience lower wear rates than conventional polyethylene liners. However, the cross-linking process does decrease the resistance of polyethylene to fatigue failure and fracture. This report describes 2 cases of highly cross-linked polyethylene liner fracture occurring in association with hip disloca...

BACKGROUND Delay to surgery for patients with hip fracture is associated with higher incidence of post-operative complications, prolonged recovery and length of stay, and increased mortality. Therefore, many health care organisations launch improvement programmes to reduce the wait for surgery. The heterogeneous application of similar methods, and the multifaceted nature of the interventions, c...

INTRODUCTION clinical guidelines recommend to identify and treat people at high risk of fracture. METHODS we have carried out a simulation concerning pharmaco-economic issues in the treatment of severe osteoporosis and particularly those people with previous femoral fragility fractures, assuming that only 13.1% of hip fractured patients had started a proper antifracture therapy, as shown by t...

BACKGROUND AND PURPOSE Recent studies have shown that compared to the posterolateral approach, the anterolateral approach reduces the risk of dislocation after hip arthroplasty in patients with femoral neck fractures. We have therefore started to use the anterolateral approach on these patients and we now report the consequences of this change for the dislocation rate. PATIENTS AND METHODS We...

Hip fractures are one of the most common injuries which present to an orthopaedic surgeon. Most of these cases are unilateral .Bilateral simultaneous femur neck fracture is a rare occurrence. We report a case of a bilateral neck femur fracture in a 30 year male following a generalized tonic clonic seizure in view of its rarity and also to increase the awareness of such rare injuries. The patien...

Failure of total hip arthroplasty through septic or aseptic loosening, periprosthetic fracture, or recurrent dislocation is well recognized and understood. We present an unusual cause of failure of total hip replacement which occurred on a 79 year old gentleman: that of prosthetic loosening secondary to malignant infiltration around components. Our aim is to highlight the fact that malignant in...
