Abstract
Abnormal callus formation around the hip joint were observed roentgenologically in paralysed extremities with injury of the spinal cord, and recognised 35 percent of callus formation among about 100 cases.
Neurogenic arthrosis have been experienced in the roentgenogram in some cases: diffuse destraction and productive change in Bone. In these cases, resection of capsule and bone near the hip joint and covering the operative defect with the total thigh flap for the hip disarticulation, were performed. However, some difficult problems have been found.
