Abstract
The invention provides a coronoid process fracture fixation device having an elongate body and a stop piece attached to one end. The elongate body is adapted for passing through the proximal ulna, across the fracture, and through the coronoid process. The stop piece, once it passes through the bone, deploys to an extended position approximately perpendicular to the elongate body and prevents the fixation device from backing out of the bone. Once inserted and the stop piece is deployed, the fixation device is fixed in place by a removable retaining device.
Claims22
A coronoid fracture fixation device, comprising:
- an elongate body having a first end and a second end;
- and
- a deployable stop piece attached at a first end of the elongate body;
- wherein said elongate body is sized and configured of a length at least sufficient to pass through a proximal ulna, across the fracture, and through the coronoid process of the proximal ulna.
A method of stabilizing a fracture of a coronoid process of the proximal ulna, comprising:
- at least temporarily reducing the fracture and holding in place with K-wire, or the like;
- making a hole through the ulna, across the fracture and through the coronoid process;
- placing a fixation device into the hole through the ulna, across the fracture and through the coronoid process;
- and
- attaching a retaining device to the fixation device.
