Abstract

PURPOSE
To evaluate the clinical and radiologic results of periacetabular osteotomy, for treating acetabular dysplasia through iliofemoral approach.
MATERIALS AND METHODS
We evaluated the results of 17 periacetabular osteotomies performed in 17 patients (12 female, 4 male). The osteotomies were performed through an iliofemoral approach in 17 hips. The mean age of the patients at the time of surgery was 34.7 years (range: 14~61 years). The average follow-up period was 26 months (range: 12~48 months). The D'Aubigine and Postel score was used for clinical evaluation. Radiological changes of acetabular head index, the CE angle (lateral and anterior), and the sharp angle were measured, respectively.
RESULTS
Clinically, the mean D'Aubigine and Postel scores improved from 12.7 preoperatively to 15.1 postoperatively. All four radiological measurements improved significantly after surgery (Wilcoxon Rank Sum test: p< 0.05). The following complications were noted: posterior column fracture in 2 hips and peripheral nerve dysfunction was noted in 5 patients. Of these nerve palsy, lateral femoral cutaneous nerve palsy in 3 patients, 1 patient complained troublesome, transient sciatic nerve palsy and femoral nerve palsy in 1 patient. There were no vascular complications or heterotopic bone formation and conversion to total hip arthroplasty.
CONCLUSION
Periacetabular osteotomy by the iliofemoral approach is an effective surgical treatment for acetabular dysplasia in adults, but should be careful nerve injuries.
