BACKGROUND AND PURPOSE Historically, a Schanz osteotomy of the femur has been used to reduce limp in patients with severely dysplastic hips. In such hips, total hip arthroplasty is a technically demanding operation. We report the long-term results of cementless total hip arthroplasty in a group of patients who had all undergone a Schanz osteotomy earlier. PATIENTS AND METHODS From 1988 throug...

BACKGROUND Acetabular bone deficiency, especially proximal and lateral deficiency, is a difficult technical problem during primary total hip arthroplasty (THA) in developmental dysplasia of the hip (DDH). We report a new reconstruction method using a medial-reduced cemented socket and additional bulk bone in conjunction with impaction morselized bone grafting (additional bulk bone grafting meth...

Most osteoarthritis of the hip is associated with chronic abnormal hip mechanics,1 related to potentially treatable anatomic abnormalities.2 The rationale of mechanically-based measures to prevent or treat osteoarthrosis assumes the following: (a) the correctable mechanical abnormality is a major etiologic factor in osteoarthrosis; (b) relief of the mechanical abnormality can prevent or improve...

A case is presented of a woman who developed obstructive jaundice secondary to dysplastic mucinous papillomatosis two years after she had undergone cholecystectomy and exploration of the common bile duct. The gall bladder was dysplastic. It is suggested that the dysplastic glands removed from the common bile duct at the second operation either represented seedlings from dysplastic areas of the ...

The relatively high incidence of labral tears among patients presenting with hip pain suggests that the acetabular labrum is often subjected to injurious loading in vivo. However, it is unclear whether the labrum participates in load transfer across the joint during activities of daily living. This study examined the role of the acetabular labrum in load transfer for hips with normal acetabular...

In order to evaluate the relationship between acetabular and proximal femoral alignment in the initiation and evolution of osteoarthritis of the dysplastic hip, the acetabular and femoral angles were calculated geometrically from radiographs of 62 patients with pre-arthrosis and early osteoarthritis. The sum of the lateral opening angle of the acetabulum and the neck-shaft angle was defined as ...

During pandemic, most common ...

Successful outcomes after psoas tenotomies have been reported and proposed in the setting of recalcitrant internal snapping impingement. However, case reports citing hip flexion weakness iatrogenic instability created concern regarding role for tenotomies. Despite these concerns, some recent studies reporting improved endoscopic breathe further life into this controversial topic. Psoas tenotomy...
