Abstract
The recurrent dislocation of hip in adult can be uncommonly induced by neuromuscular disease or dysplasia of hip. But in the case of traumatic dislocation of hip with acetabular fracture, the possibility of recurrent dislocation can be decreased if treated with accurate fixation or traction. We have experienced a case of hip dislocation with comminuted acetabular fracture, which was treated only with soft tissue suture and without fixation because of severity of the acetabular fracture. An inappropriate conservative management was done during the post operation period, eventually result in recurrent dislocation and degeneration of posterior wall and head of femur which resembled bony Bankart lesion of the shoulder. The reduction was not able to be maintained, as a result THRA was done. A year after the operation, good prognosis was found in replaced hip without any recurrent dislocation.
Figures and Tables
Fig. 1
(A) Anteroposterior radiograph of the both hip and (B) CT scans show intraarticular osteochondral fragment and posterior wall fracture of acetabulum.
Fig. 2
Preoperative axial CT scans show 30-40% bony defect of posterior wall of acetabulum and intraarticular osteochondral fragment.
Fig. 3
(A) This photography shows bone and soft tissue fragments after operation. Fixation could not be done due to severe comminuted fracture. (B) Immediate postoperative anteroposterior radiograph shows satisfactory reduction.
Fig. 4
Anteroposterior radiograph of the right hip shows fracture-dislocation and defect of posterior wall of the acetabulum.
