Modified kloen approach treatment for acetabular fractures.

To evaluate the feasibility and efficacy of modified Kloen approach for the treatment of ace tabular fractures through lateral window exposure beneath fascia iliaca with superior ramus of pubis exposure by internal small incision. Matta radiological criteria was employed to evaluate the post operation recovery, and modified D'Aubigne-Postel evaluation system was adopted for demonstration of hip joint function condition. There is no incision infection, neurovascular trauma or postoperative lymphorrhagia. 42 patients cooperated with the following up of 11.2 months. The average bone healing time was 13 weeks. Matta radiological criteria was to evaluate the postoperative fracture quality, 18 case with excellent recovery, 16 cases with good recovery, 4 cases with normal recovery and 1 case with bad recovery. Modified D'Aubigne-Postel evaluation was taken 6 months after surgery, 17 cases with excellent recovery, 22 cases with good recovery, 2 cases with normal recovery and 1 case with bad recovery. There was no internal fixation loosening, breakage or inguinal hernia. The modified Kloen approach can improve iliofemoral vascular activity, expense exposure range for restoration and fixation. Besides, the exposure of articular surface could ensure the condition of restoration quality, and avoid the incidence of postoperative hernia.
