System for stabilization of fractures of convex articular bone surfaces including subchondral support structure
View Patent ↗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.
1. 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.
2. A proximal humeral fracture fixation system according to claim 1 , further comprising:
a second rigid cross support extending through a distal portion of said second post.
3. A proximal humeral fracture fixation system according to claim 1 , wherein:
said first and second posts extend in an anterior-posterior plane.
4. A proximal humeral fracture fixation system according to claim 1 , wherein:
said first and second posts extend in a proximal-distal plane.
5. 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.
6. A proximal humeral fracture fixation system according to claim 5 , wherein:
wherein said cross peg extends in an anterior-posterior plane.
7. A proximal humeral fracture fixation system according to claim 5 , wherein:
said post includes a plurality of peg holes, and said rigid cross peg can extend through any of said peg holes.
