Abstract
A method and device for attaching with compression artificial joint implants to the ends of bone by means of an independent anchor and dead man (1).
Claims1
An apparatus for retaining a joint implant comprising:
- an anchor implantable within a bone, said anchor defining a longitudinal axis and having a lower proximal end and upper distal end, the upper distal end being widened relative to the lower proximal end and defining at least two, spaced, threaded apertures, the lower proximal end defining a single aperture, with said single aperture being angled with respect to said longitudinal axis;
- two threaded countersunk bolts connectably engaging two of said apertures in said anchor and extending above the edge of said bone for retaining the implant on the bone edge;
- a dead man bolt having a head portion and a threaded portion, said dead man bolt extending through said single angled aperture so that said head and threaded portion of the dead man bolt engage outer cortical portions of the bone and retain the anchor within the bone.
