Prosthetic femoral rod for use during hip plastic surgery, has neck forming part including covering region, covered with coating to ensure regrowth of bone, at level of its proximal end, where region is extended on periphery of part

摘要

The rod (2) has an elongated medullary part (4) engaged in a medullary cavity of a femur and including traversing transversal holes (5a, 5b) which house a femur traversing screw. A prosthetic femoral neck forming part (3) with a prosthetic femoral head, is projected from the femur. The part (4) has a covering region (8), covered with a coating to ensure the regrowth of a bone, at the level of its proximal end, where the region is extended on the periphery of the part. The coating is made of resorbable material e.g. tricalcium phosphate and hydroxyapatite.
