Perthes disease and relief of weight bearing

: Authors compare in two different groups of treatment the results of varus derotation osteotomies in Perthes' patients treated on the Department of Orthopaedics of the Pecs University of Medicine in 1974-1984. In 30 cases running was allowed after the osteotomy whereas in 52 cases an apparatus to relieve of weight bearing was used. It is stated after the comparison of results, considering also the role of the "risk" factors, influencing the results that the relieve of weight bearing does not influence the end result.
