The neglected traumatic dislocation of hip in children and adults are uncommon. The various treatment modalities in adults include closed reduction, open reduction, heavy traction in abduction, intertrochanteric/subtrochanteric osteotomy, girdlestone excision arthroplasty, arthrodesis, hemiarthroplasty and total hip replacement. The closed reduction can be achieved following injuries less than 3 weeks old. Beyond 3 weeks closed reduction with heavy traction is attempted failing which open reduction is advocated. The presence of associated fracture of acetabulum should also be fixed. Open reduction is required for all dislocation beyond 12 weeks failing which reconstructive procedures such as total hip arthroplasty or arthrodesis are indicated depending on the social need and acceptance by the patients. Those late reconstructive procedures may be technically difficult because of extensive scaring, shortening, avascular necrosis of the femoral head and acetabular disruptions. Neglected traumatic dislocation of hip in children is rare. They occur following a trivial fall hence missed. Closed reduction may be attempted with caution in dislocation less than 3 weeks old. It is difficult to achieve closed reduction with heavy traction if dislocation is more than 3 weeks old. Open reduction is advisable to restore anatomy for neglected dislocation of any length of time knowing fully well that almost all of them will develop avascular necrosis. Still the remodeling and revascularization gives good clinical result.
