The Birmingham mid head resection (BMHR) arthroplasty can be used as an alternative to conventional stemmed total hip arthroplasty in young patients unsuitable for hip resurfacing. This study investigated the effect of stem size on femoral neck fracture in the BMHR. Sawbones composite femurs were randomly allocated to one of the following groups: (1) unprepared femur with no prosthesis, (2) fem...

BACKGROUND Questions regarding the distribution of stress in the proximal human femur have never been adequately resolved. Traditionally, by considering the femur in isolation, it has been believed that the effect of body weight on the projecting neck and head places the superior aspect of the neck in tension. A minority view has proposed that this region is in compression because of muscular f...

Background: The hip essentially represents the major weight-bearing joint of the human organism. It is conspicuously characterized by its mobility and complex origination, specific organization and development. The anatomic structures referred to as acetabulum and femoral head arise from the same primitive mesenchymal cells and, by the end of the 11 week of gestation, the hip joint becomes full...

Suppurative arthritis of the hip in infancy and early childhood inflicts permanent damage of variable severity if it is not treated promptly and aggressively (Paterson I 970). Damage is sometimes limited to the articular cartilage alone, but in neonatal infection there is commonly destruction and displacement of the joint. This often follows consistent patterns and presents opportunities for re...

In the treatment of medial fractures of the femoral neck by the Smith-Petersen nail one can distinguish two problems: the first concerns failure to initiate the process of union, as shown by complete separation of the head and the recurrence of the original deformity; the second concerns necrosis and collapse of the femoral head after successful union at the site of the fracture. Complete separ...

INTRODUCTION More than two years delay in the union of fracture neck of femur is a very rare entity.The treatment of an established non union depends on numerous factors including age of the patient, vascularity of the femoral head and other factors. It is timing of intervention that is not clearly defined in the literature. CASE PRESENTATION We report 2 cases where fracture neck of femur in ...

In general practice, short films of the knee are used to assess component position and define the entry point for intramedullary femoral alignment in TKAs; however, whether it is justified to use the short film commonly used in research settings and everyday practice as a substitute for the whole leg view is controversial and needs clarification. In 138 long leg CT scanograms we measured the an...

The Birmingham Mid Head Resection (BMHR) arthroplasty can be used as an alternative to conventional stemmed total hip arthroplasty in young patients unsuitable for hip resurfacing. This study investigated the effect of stem size on femoral neck fracture in the BMHR.

Condylo-cephalic nailing which has been developed by Ender is described. Three elastic pins are inserted at the proximal part of the medial femoral condyle and passed through the femur across the fracture into the head of the femur. The operative procedure is very simple and not hazardous to elderly patients. A special advantage is early weight-bearing. One hundred and three patients with inter...
