modified innominata osteotomy in the treatment of severe acetabular dysplasias - 5 years' experience in Kuwait

ABSTRACT

A modified innominate osteotomy for the correction of severe acetabular dysplasia was used between 1992 and 1996 in 15 children for whom there were complete clinical and radiological data up to February 1998. The average age at the time of surgery was 32 months [range 17 to 50]. Congenital dislocation of the hip was bilateral in 8 cases, left-sided unilateral in 4 and right-sided unilateral in 3. The duration of post-surgery follow-up averaged 4 years [range 2 to 6]. Case evaluation for all patients was very good [McKay clinical and radiological classification]. Correction of the acetabulum index angle by this modified pelvic osteotomy was increased up to 40 degrees, as compared with 15 degrees, obtainable in the classical Salter innominate osteotomy
