摘要 |
A femoral component of a hip implant is disclosed. The femoral component may be used specifically in a neck sparing resection (i.e., any process or device that avoids removing the femoral neck) and may include a shortened stem (with respect to a conventional stem) having a terminal flare portion for internally contacting a medial calcar portion of the proximal femur, and a significant curvature on its medial side. Other features of the femoral component include, flat side portions on the anterior and posterior sides of the stem, a lateral fin or a wing or T-back to aid in resisting torsional forces. The femoral component may also include a sagittal slot for proper fitting and placement in the femoral canal. The femoral component may also include a neck component that is modular with respect to the stem component. A head component, whether monoblock or modular with respect to the neck component, may also be utilized as part of the femoral component. |
