Treatment of canine hip dysplasia: a review.
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 with moderate to severe osteoarthrosis. In young animals with joint laxity and pain, but with no or minimal radiographic evidence of osteoarthrosis, the treatment approach is controversial. Conservative management may be effective in the short term, but progressive development of osteoarthrosis occurs and clinical signs may manifest at an older age. Options for surgical treatments in these young dogs include pectineal myectomy, lengthening of the femoral neck, and corrective osteotomies. Corrective osteotomies are advocated to reestablish joint congruency and prevent development of osteoarthrosis. In the mature osteoarthritic dog, effective conservative management depends on the severity of the degenerative joint disease. Proposed surgical treatments for clinically debilitating hip dysplasia include biocompatible osteoconductive/shelf arthroplasty; femoral head and neck excision arthroplasty, with or without muscle sling interposition; and total hip replacement. Although research directly comparing the salvage procedures has not been reported, studies suggest that total hip replacement is more effective in returning large dogs to full functional weight bearing.
