Abstract

FROM THE DEPARTMENT OF ORTHOPEDIC SURGERY, MALMO ALLMANNA SJUKHUS, S-214 01 MALMO, SWEDEN. THE SPHERICAL INDEX A measure of the roundness of the femoral head N. FREDENSBORG For the investigation of the results of treatment of congenital dislocation of the hip with the von Rosen splint (FREDENSBORG 1976) it was necessary to design a method for evaluation of the shape of the femoral head. Several methods have been presented. EYRE-BROOK (1936) introduced the epiphyseal index to assess the results in Perthes's disease (coxa plana). Unfortunately, the points of measurement are sometimes difficult to define and in older children and adults the remnants of the epiphyseal plate may be impossible to identify. The 'comprehensive quotient' introduced by HEYMAN & HERNDON (1950) includes measurement of the epiphyseal index and is, therefore, not applicable in older age groups.
