FIELD: medical engineering. ^ SUBSTANCE: device has cotyloid cavity part, head, neck, trochanteric segment and leg. The ellipsoid head has its longer axis being placed at intersection horizontal and frontal planes. One of its short axes is placed at the intersection of sagittal and frontal plane. The second short axis is in the intersection of the sagittal and horizontal planes. Contact surface of the cotyloid cavity is congruent to head surface. ^ EFFECT: reduced probability of contracture recurrence. ^ 6 dwg |
