HIP JOINT ENDOPROSTHESIS Russian patent published in 2003 - IPC

FIELD: medical engineering. SUBSTANCE: device has acetabular part, head, neck, trochanteric part and pedicle. Aligning cylinders are axially movably mounted in proximal tubular pedicle portion. The cylinders are separated by sealed bellows fixed on their bases and filled with biologically inert gas under pressure. Distal bellows is attached to tubular pedicle portion bottom. Proximal aligning cylinder is connected to cylindrical portion of the trochanteric part axially movably mounted in proximal segment of the tubular pedicle portion by means of rod having square cross-section. The rod is axially movably mounted in matching form of support member separated from proximal aligning cylinder with flexible elastic inlay. EFFECT: enhanced effectiveness of treatment; high stability of prosthesis pedicle position. 1 dwg
