It is well known that dislocation or subluxation of the hip joint can be produced in young rat by immobilizing the knee joint in extention. In the present study, the left knees of four-week-old Sprague-Dawley rats were immobilized in extension by intramedullary insertion of a pin. Seventeen weeks after operation, bilateral iliopsoas muscles were removed and stained for ATP-ase according to Padikula and Herman method (pH9.4). Histometrical analysis was done by employing a photograph of the cross-sectional area where the distribution of type I fibre was most predominant. The proportion of type I fibre in the psoas minor and iliacus muscle was increased on the immobilized side, but this increase was significant only in the iliacus muscle. Cross-sectional areas of both fibre types in the iliacus muscle were increased in the immobilized side, but those of psoas minor muscle were decreased. Partial distribution of type I fibre in the iliacus muscle and psoas minor muscle was not changed by the treatment, and type I fibre was not found in the psoas major muscle of both sides.
