INTRODUCTION: The presence of a damaged labrum is one of many factors influencing the outcomes of Chiari pelvic osteotomy. However, there are few previous papers describing the long-term outcomes of Chiari pelvic osteotomy with labrectomy. The purpose of this study was to evaluate the long-term clinical and radiological outcomes of Chiari pelvic osteotomy for dysplastic hips with labral tears. We compared outcomes between labrectomy (+) and labrectomy (-) groups. PATIENTS AND METHODS: Chiari pelvic osteotomies were performed by one surgeon on 34 dysplastic hips with labral tears between 1983 and 1996, in which labrectomy was performed on 23 hips but not on 11 hips. Three patients undergoing labrectomy were lost to follow-up evaluation within 5 years after surgery. The average age of the remaining 31 patients was 35.5 years (range, 16-54 years). The clinical and radiographic surveillance averaged 16.0 years (range, 10-23.3 years). RESULTS: In all patients, pain disappeared after the operation. At the end of the study, 8 of the 31 patients displayed clinical deterioration. Progression of osteoarthritis (OA) was observed in 11 hips. Patients with poor results have not opted for revision surgery except for one patient. In the labrectomy (+) group, 10 of the 20 hips showed progression of OA and the clinical outcomes of 6 patients deteriorated. In the labrectomy (-) group, 1 of the 11 hips showed progression of OA and 2 patients deteriorated clinically. Radiological outcomes differed significantly between the two groups. CONCLUSION: Labrectomy accompanying Chiari pelvic osteotomy is an acceptable procedure for relieving pain caused by the damaged labrum, but the outcomes have a tendency to deteriorate after 10 or more years postoperatively.
