title: Open reduction for neglected traumatic hip dislocation in children and adolescents.
abstract: Neglected traumatic dislocation of the hip is extremely rare in children, and the preferred treatment remains unclear. This retrospective case series includes 8 children treated by open reduction. The mean age was 7.5 years (range, 2-16 years), and the mean follow-up was 7 years and 7 months (range, 4 month-16 years). Presenting complaints included pain (5/8) and gait disturbance (8/8). Traction failed to achieve a reduction in all cases. At follow-up, 6 hips remained reduced, and 2 achieved a non concentric reduction. All patients had evidence of avascular necrosis. Two patients, in whom a non concentric reduction was achieved, developed progressive flattening and joint space narrowing. Two patients had mild pain at follow-up, and 6 patients were able to squat. Range of motion was restricted both before and after open reduction, most notably in abduction and rotation. Postoperative improvement was seen in abduction (4 cases). Leg lengths were within 2 cm in 7 of 8 cases, and only 1 patient had a discrepancy greater than 2 cm. The results according to Garrett et al were good in 3, fair in 3, and poor in 2. The mean Harris hip score was 89. Patients with a concentric reduction had an adequate functional outcome despite evidence of avascular necrosis. The prognosis remains guarded, and we expect that a subset of patients will develop premature degenerative joint disease. However, we continue to offer patients an operative reduction, which we feel is preferable to other methods. A failed open reduction does not preclude options for salvage.
