Due to the widespread use of surgical interventions that help preserve hip function in hip disease, the number of arthrodesis - traumatic interventions involving dislocation of the femoral head from the articular socket and resection of the articular surfaces - has decreased. As a rule, joint locking is now performed only in cases where there is no alternative, i.e., when there is minimal rocking motion in the joint. In such cases, the traumatic open resection arthrodesis is replaced by the less traumatic so-called closed periarticular arthrodesis. However, since closed arthrodesis is performed without dislocating the femoral ball head, the subsequent fixation of the femoral ball head in the socket is difficult.
