The role of acetabulum geometry and femoral head-neck ratio in the development of osteoarthritis in young men.
We studied the role of acetabulum geometry and head neck ratio in the development of osteoarthritis of the hip in young men. Contrary to previous studies we evaluated the significance of the anterior, posterior and total coverage of the femoral head, the influence of the femoral neck and the consequence of acetabular retroversion on standardized x-rays. Men aged 26-55 years who earlier had a total hip arthroplasty were included in the case group. This group was compared to a control-group of men treated as trauma patients. The study indicates that acetabular dysplasia and retroversion and a relative decreased head neck ratio are associated with osteoarthritis of the hip in young men.
