Kuwait has a very high incidence of all types of developmental dysplasia of the hip. One of the most complicated forms is the deformed dysplastic acetabulum, which has not only abnormal orientation but it also has lost its shape by the pressure of the subluxed femoral head. The outer part of the socket involves the upper part of the original acetabulum, thus giving it a bipartite appearance. Cl...

We have divided Severin group-V severely dysplastic hips with a false acetabulum into three subtypes, based on the height and shape of the socket. We performed rotational acetabular osteotomy (RAO) in 19 hips in 17 young adults with a type-1 'low' false acetabulum which had direct contact with the true acetabulum. This is a periacetabular osteotomy which gives acetabular coverage with articular...

INTRODUCTION Revision acetabulum arthroplasty is one of the common procedures, which has been on the rise recently. Many implants are available in the market with variable results. Aseptic loosening is the most common indication for revision acetabulum arthroplasty. Birmingham dysplasia cup has been used occasionally in these complex procedures. We know that these implants have provided good re...

The acetabular rim syndrome is a pathological entity which we illustrate by reference to 29 cases. The syndrome is a precursor of osteoarthritis of the hip secondary to acetabular dysplasia. The symptoms are pain and impaired function. All our cases were treated by operation which consisted in most instances of re-orientation of the acetabulum by peri-acetabular osteotomy and arthrotomy of the ...

The hips of twenty full-term African neonates have been examined in detail to determine any anatomical factors which might explain the difference in the incidence of congenital dislocation of the hip in the African and in the Caucasian. Measurements included the degree of anteversion of the femoral neck and the acetabulum and the diameter and depth of the acetabulum. The acetabulum tended to be...

CASE REPORT A 79-year-old woman sustained a left anterior column acetabulum fracture after falling on ice. On initial presentation to the emergency room she was placed in femoral pin traction. The reduction of the acetabulum in traction was not concentric and the femoral head began to migrate centrally. Treatment options, including primary THA after the acetabulum fracture healed, were discusse...

Osteonecrosis in isolated fractures of the acetabulum without dislocation of hip seems to be a known complication, but to our knowledge it has not been reported adequately. The causative nature of post-traumatic femoral head osteonecrosis has not been studied critically. The pathophysiology of osteonecrosis in this case also eludes us. Striking evidence points towards the intra-operative blood ...

conclusions we recognized this type of fracture and treated it similarly to both column fractures. we recommend that the classification of acetabular fractures be modified to include this type of fracture. introduction acetabular fractures are a common problem among young males. an acetabular fracture with disruption of the joint surface, if untreated, will rapidly lead to post-traumatic osteoa...
