Introduction
We report the short-term outcomes of total hip arthroplasty(THA) in patients previously treated with Schanz osteotomy (SO).
Materials and methods
Eighteen patients [2 male, 16 female; mean age, 55.4 (range, 50–66) years] who had undergone THA after SO were retrospectively evaluated. Clinical evaluation was performed based on the Harris hip score. Radiological evaluation was performed using full-length radiographs of the lower extremities, pelvis, and hip.
Results
The mean follow-up period was 30.8 (range, 18–56) months. Mean femoral shortening was 3.7 (range, 2–5) cm. Perioperative complications occurred in 4 (22.2%) patients. Nonunion was not found at the osteotomy sites. No dislocation was observed. The Trendelenburg sign was positive for five (27.7%) patients, postoperatively. The mean Harris hip score improved from 42.7 to 78.7 (p < 0.05).
Conclusion
THA for hips previously treated with SO is technically demanding. If careful preoperative planning is performed, successful treatment can be achieved.
