To assess clinical and radiological results of combined pelvic osteotomy (CPO) for deformed dysplastic acetabula.
Methods.
Nine girls and 3 boys, aged 28 to 54 months, underwent CPO (combination of innominate osteotomy and Lance acetabuloplasty) to restore both the original shape and the mal-alignment of the acetabulum. They were followed up for at least 5 years.
Results.
All patients attained concentric stable reduction with good acetabular cover.
Conclusion.
CPO corrected both deformed and dysplastic acetabula and prevented postoperative subluxation.
