Abstract
A fracture fixation system is provided for a fracture of a head portion of a long bone which has subchondral bone defining a convex articular surface. The system includes a plate element positionable on the long bone substantially opposite the head portion of the long bone and on a first side of the fracture, and a post coupled to the plate and into the head portion of the bone and across the fracture. A cross peg is coupled to the post to provide support of the subchondral bone.
Claims7
A proximal humeral fracture fixation system, comprising:
- a) a plate including first and second post holes;
- b) a firstpost mechanically coupled in said first post hole in a rotationally fixed manner;
- c) a first rigid cross support extending through a distal portion of said first post;
- and
- d) a second post mechanically coupled in said second post hole.
A proximal humeral fracture fixation system, comprising:
- a) a proximal humeral plate including a head portion with a post hole and a shaft portion with at least one bone screw hole;
- b) a post insertable into said post hole and including a peg hole;
- c) first means for rotationally fixing said post in said a post hole such that said peg hole is in a predetermined orientation;
- and
- d) a rigid cross peg extending through said peg hole.
