Abstract: The orthopaedic endoapparatus designed to grow a new live shoulder and hip joint, to reconstruct a deformed joint or to restore a pathologically dysplastic and congenitally luxated joint, contains a figured hinge, consisting of a spherical knob engaged with a curved guiding member. The spherical knob is linked by an expandable connecting turnbuckle with an anchor-like pair of curved rods to secure the fixation of the endoapparatus to the hip or shoulder bone, while the guiding member is connected with an anchor-like member fastening the endoapparatus to the pelvis or to the scapula and clavicula.
