ENDOPROSTHESIS OF THE HIP JOINT Russian patent published in 2003 - IPC

FIELD: medical engineering. SUBSTANCE: device has head, neck, trochanteric part and lateralized pedicle. The trochanteric part has proximal and distal portion controllably joined by means of dovetail connection to allow moving each of them relative to the other. Cylindrical canal is produced in distal portion of the trochanteric part. The canal is open with its longitudinal groove towards the proximal portion. Tail screw is rotatably mounted in the canal, the buttress thread of the screw projects via longitudinal groove and is arranged finds place in response groove of proximal portion thread of the trochanteric part. The lead screw ends have restrictors. The lead screw tail is deflected from pedicle axis by an angle exceeding 90 deg. EFFECT: enhanced effectiveness of treatment; eliminated muscle unbalance. 4 dwg
