Residual hip dysplasia is one of the most common causes of secondary osteoarthritis of the hip joint. It is suggested that excessive hip joint contact stress due to small weight-bearing area is an important precipitating factor for the development of hip arthrosis (Hadley et al., 1990; Hipp et al., 1999; Maxian et al., 1995). Dysplasia of the hip refers to mechanical deformations and deviations...

Between June 1988 and December 1997, we treated 332 babies with 546 dysplastic hips in a Pavlik harness for primary developmental dysplasia of the hip as detected by the selective screening programme in Southampton. Each was managed by a strict protocol including ultrasonic monitoring of treatment in the harness. The group was prospectively studied during a mean period of 6.5 +/- 2.7 years with...

Adult patients with developmental dysplasia of the hip develop secondary osteoarthritis and eventually end up with total hip arthroplasty (THA) at younger age. Because of altered anatomy of dysplastic hips, THA in these patients represents technically demanding procedure. Distorted anatomy of the acetabulum and proximal femur together with conjoined leg length discrepancy present major challeng...

Total hip arthroplasty (THA) for osteoarthritis secondary to development dysplasia of the hip (DDH) is facing increasing levels of complexity with increasing grade of deformity. The dysplastic acetabulum is characterized by diminished bone stock with decreased lateral coverage. Therefore, it is challenging to restore the anatomic center of rotation and ensure adequate acetabular component fixat...

Total hip arthroplasty relieves pain and improves function for many patients with endstage arthritis secondary to developmental dysplasia of the hip. Acetabular dysplasia, however, presents a special problem for total hip reconstruction in these patients. Structural bone grafting with femoral head autografting to the dysplastic acetabulum and cementing acetabular components into the graft provi...

The natural history of an untreated case of a Developmental Dysplasia (Dislocation) of the Hip (DDH) associated with multiple congenital abnormalities is reported in a 55-years-old man. The patient's complaints and the varieties of the typical manifestations emerged in other parts of the body throughout the life are reviewed and discussed as comorbidities of a dysplastic condition. Two-stage bi...

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 ...

This article discusses the treatment approaches and recommendations for canine hip dysplasia. A search of the literature database MEDLINE (1969-1994) was conducted and relevant journal articles regarding the medical and surgical treatment of hip dysplasia were selected and reviewed. Dysplastic dogs can be divided, for treatment purposes, into those with no or minimal osteoarthrosis, and those w...
