Surgical clamp for fixation of bone fragments
First Claim
1. An implantable surgical buttressing means for fixation of one or more bone fragments to an adjacent stable bone, said buttressing means comprising a first part of U-shape including a U portion and two legs extending from said U portion to bear along an extraosseous surface of a stable bone, a bone screw for securing said first part against said stable bone, said legs having bends to pass through a fracture space between adjacent bone fragments and respective distal ends shaped to bear against an intraosseous surface of at least one said bone fragment and provide a buttressing action thereagainst without drilling into said at least one bone fragment.

Abstract
The present invention relates to an implantable clamp for fixation of one or more bone fragments (82, 85) to a stable bone (81). The clamp has two basic functions, namely a buttress function and a clamp function. Either function or both may be employed depending on the fracture picture. The clamp has a first part (71) having a front part bent into a buttress (79) and/or into a lower part (77) of a clamp. Further, the clamp may comprise a second part (72) constituting the upper part (73) of the clamp. A screw (74) is used to secure the clamp to the stable bone (81). The buttress (79) of the clamp is utilized to press an intra-articular fragment (85) against an adjacent joint surface. The clamp (73, 77) is utilized to capture and secure a bone fragment (82).

- 11. An implantable surgical clamp means for fixation of one or more bone fragments to an adjacent stable bone, said clamp means comprising a first part for bearing along an extraosseous surface of a stable bone, a bone screw for securing said clamp means against said stable bone, a second part supported from said first part, said first and second parts having distal ends spaced from one another so that the distal ends of said parts can respectively bear against the extraosseous and intraosseous surfaces of at least one bone fragment to sandwich said at least one bone fragment between the distal ends of the first and second parts, one of said parts being of U-shape and including a U portion and two legs extending in spaced relation from said U portion and means for securing said first and second parts together.
