Description

COLLO-MIS

The Collo MIS short stem is designed for femoral neck conservation, coated with double coating of PoroTI and hydroxyapatite.

The Collo MIS femoral stem is the prosthetic solution for femoral bone preservation. The stems elliptical cross-section design allows primary fixation in the femoral neck without changing the neck-diaphysis angle (CCD angle). Longitudinal fins increase the stems stability even in the presence of torsional loads, the shortened neck reduces the incidence of lengthening of the leg with resultant stretching of muscles and tendons. The medial curvature of the stem varies with varying size to enable a physiological load transmission, the distal tip of the stem is not coated to reduce risk of stress shielding.

The Collo MIS stem is indicated for primary or secondary osteoarthritis and avascular necrosis of the femoral head, in the absence of severe deformity of the femoral neck.
