Abstract:
Retroversion of the adult acetabulum following a previous Legg-Calvé-Perthes disease (LCPD) is found in 30-40% of the patients. It is known that in LCPD there may also be morphologic changes in the nonaffected controlateral acetabulum. We investigated the prevalence of retroversion of the contralateral acetabulum in a group of adult patients with a history of LCPD. We found this morphology in 11 out of 36 patients (31%). The aetiology and its relation to Perthes' disease are discussed.
