US 5,743,912 A · Upper femoral epiphysis osteosynthesis implant

Abstract

A longitudinal revascularization conduit is formed in the body of an implant. It is blind at the distal end of the body to be implanted in one bone fragment, such as the trochanter, and open via transverse orifices and at the proximal end of the body to be implanted in another bone fragment, such as the femoral head. At least one self-tapping section situated at the distal end of the body immobilizes the body in the bone, or an anchor end-piece is slidably mounted on the body and contains a damping device adapted to push the end-piece in the proximal direction and the body in the distal direction in order to maintain the fracture in compression. The distal end of the body may be mounted in a cylindrical portion of a plate secured on the diaphysis of the femur.

Dependent claims

An implant for osteosynthesis of a fracture between first bone fragment and a second bone fragment, comprising:

(a) an elongate implant body having a proximal end and a distal end, said implant body containing a longitudinal conduit extending from an opening in said proximal end toward said distal end, said body also containing a plurality of longitudinally spaced through openings extending radially outwardly from said conduit, said body proximal end being adapted for insertion within alined bores formed in the first and second bone fragments on opposite sides of the fracture;
and
(b) first self-tapping means arranged at one end of said body for connecting said body one end with the associated bone fragment.
