Nonarthroplasty surgical treatment of hip osteoarthritis

The two conditions that give rise to osteoarthritis of the hip are dysplasia and nondysplasia. Dysplasia, commonly associated with anterolateral acetabular deficiency, may lead to osteoarthritis in 40% of patients in the United States with this condition. In a distinct category of patients with so-called idiopathic arthritis, there is no apparently identifiable cause for osteoarthritis. There is emerging evidence that subtle morphologic abnormalities around the hip, resulting in femoroacetabular impingement, may often be a contributing factor to osteoarthritis in young patients.
