Abstract
Traumatic dislocations of the hip joint are high energy and uncommon injuries. Traumatic anterior dislocation accounts for about 10% of all hip dislocations and is classified into superior and inferior types. We experienced 3 cases of superior type anterior hip dislocation. The average age was 33 years and the follow-up period ranged from 3 to 12 months, averaging 7 months. Secondary osteoarthritis and avascular necrosis (AVN) of the femoral head are reported as complications of anterior hip dislocation. The prevalence of AVN may be higher when reduction is delayed for more than 24 hours. All our patients took early reduction, averaging 2.5 hours, post injury one open reduction and the others closed reduction. Good ROM was achieved and pain disappeared. No arthritis and AVN of the femoral head were seen. After reduction, all our cases were inhibited with weight bearing for more than 3 weeks. All achieved good clinical results, but further follow-up is required.
