Appts. for restoration of hip joint mobility - in which frontal and sagittal planes are yoke connected and fastened through hinged joint to thigh bone

A pelvic yoke (1) is secured on the upper flaring portion of the ilium by means of traction wires (3). A distractor (10) with provision for adjusting movements in two mutually perpendicular planes, the frontal and the sagittal, is connected with the yoke and is fastened through a hinged joint to the thigh bone. The hinged joint is formed by rollers (14) disposed on an arc-like guide (7) situated in the frontal plane and is fastened to the greater trochanter (28) of the thigh bone by nails (8). The hinged joint comprises also a spherical locking joint (15) fastened on the distractor and adjusting screws (21, 22) provide for adjustment in two mutually perpendicular directions. The appts. gives complete support of a hip joint during its healing and may also include a thigh yoke. Selon l'invention, l'appareil comporte un étrier coxal 1 qui se fixe au moyen de broches 3 sur les ailes des os iliaques 2. Un distracteur 10, qui peut effectuer des déplacements de réglage dans deux plans perpendiculaires l'un à l'autre, à savoir le plan frontal et le plan sagittal, est relié à l'étrier coxal; un dispositif articulé Il à 15 permet la fixation du distracteur sur l'os fémoraL L'utilisation de cet appareil assure le soulagement complet de l'articulation coxo-fémorale au cours de sa guérison D'autre part, cet appareil peut assurer la réduction graduelle et dosée de la luxation fémorale, puis la rééducation dosée de l'articulation.
