This report describes the surgical treatment for an unreduced traumatic dislocation of the hip with 3-dimensional (3D) replica construction and implantation of a total hip arthroplasty (THA).
A 63-year-old male patient, was referred to our hospital because of right hip pain related to a motorbike accident for which he had undergone conservative treatment of a right lower leg fracture 42 years previously. At three months post-fracture, the patient underwent a radiographic review of the hip joint because of ongoing pain in his right hip. A dislocation fracture of the right hip was identified, but it was subsequently neglected.
When the patient visited our hospital radiographs and computed tomography scanning showed a posterosuperior dislocation of the right hip with severe post-traumatic arthritis. Because of the severely abnormal anatomy, we constructed a 3D replica for pre- and intraoperative planning. By using 3D replica, we were able to examine installation position of cup and resection range of soteophyte before operation. Additionally, we performed a THA without complications even as for the limited view using 3D replica as intraoperative navigator. At 18 months postoperatively, the short term result indicated a good functional result.
