Hip dislocation without fracture: traction or mobilization after reduction?

In all, 41 patients with traumatic dislocation of the hip, without associated acetabular or femoral fracture, were treated by two different methods after closed reduction, performed on average 2 h after injury. Patients in group A (N = 20) were subjected to skeletal traction for 2 weeks, followed by non-weight bearing for 3 months. Those in group B (N = 21) were mobilized a few days (average 9 days) after injury and allowed partial weight bearing. They were fully weight bearing at 3 months. The 31 patients were followed up for an average of 7.6 years and showed comparable long-term results in both groups. No early complications occurred in group B. There were no cases of avascular necrosis in either group. There were three cases of post-traumatic arthritis in group A and one in group B, and two cases each of heterotopic ossification. Early mobilization was concluded to be a safe and more comfortable method of after-treatment. Earlier return to work was a significant benefit in Group B.
