INTRODUCTION Management of developmental dysplasia of hip in adult is challenging problem. Management protocols are not well defined in terms of operative technique. Patient may present very late. Usually they consult orthopaedic surgeons when osteoarthritic changes set in, leading to pain. Operative management is difficult because of difficult exposure, altered anatomy of soft tissue structure...
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...
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...
The Ganz periacetabular osteotomy (PAO) is currently the most popular hip-sparing procedure in adults with acetabular dysplasia. If this procedure fails and a total hip arthroplasty is necessary, spatial reorientation of the acetabulum alters the conditions of implanting the acetabular component of the prosthesis. In our study, we present two cases of total hip arthroplasty in patients who had ...
Hip dysplasia is an important and complex genetic disease in dogs with both genetic and environmental influences. Since the osteoarthritis that develops is irreversible the only way to improve welfare, through reducing the prevalence, is through genetic selection. This study aimed to evaluate the progress of selection against hip dysplasia, to quantify potential improvements in the response to ...
I n 1967, Bachman described a ‘‘hereditary peripheral dysostosis’’ which affected a mother and her two children. What was later considered as multiple epiphyseal dysplasia combined with phalangeal cone shaped epiphyses was renamed angel shaped phalangoepiphyseal dysplasia (ASPED) and considered as a genetic bone marker. ASPED represents a further variety of multiple epiphyseal dysplasia and is ...
Orthopaedic treatment of congenital hip dysplasia does not always give the desired result. With the present model, prediction of the effects of various treatments on the force direction in the hip joint could help to improve and select treatment (the force direction is presumed to control the collum growth direction). The model contains three-dimensional mathematical descriptions of all muscles...
We have determined the natural history of hip development in 42 patients with multiple epiphyseal dysplasia (MED). Premature osteoarthritis was a frequent outcome and was almost inevitable before the age of 30 years in those with incongruent hips. There were two types of immature hips: type I, the more severe form, had a fragmented and flattened ossific nucleus and acetabular dysplasia, was mis...
Ventrodorsal pelvic radiographs were made of 32 adult dogs under general anaesthesia. The hip joints were evaluated according to the severity of osteoarthritic changes graded as 0, 1, 2 or 3. The dogs were euthanased, the hip joints opened and the ligamentum capitis femoris dissected out in toto. The volume of each ligament was determined using a water displacement technique and the mean volume...
OBJECTIVE : To determine ethnic variations of acetabular morphology, and to delineate their relationship with hip osteoarthritis (OA). METHODS : Radiographs of 283 French men, 118 French women, 414 Japanese men and 368 Japanese women, aged 20-79 yr, who underwent intravenous urography were assessed by a single observer for morphometric measurement and hip OA scoring. RESULTS : The standardi...
