Abstract
Provided is a slot anchor guide that includes a medial portion and a lateral portion, the medial portion includes a medial projection configured to span a slot of a fixation plate, where the slot anchor guide is configured to guide an anchor through a predetermined position of a slot of the fixation plate and to mate with the fixation plate to allow a surgeon to place the fixation plate on a bone face by manipulating the lateral portion. Also provided is a tuberosity fracture plate that includes a tuberosity end having a first portion configured to overlay a first tuberosity and a second portion opposite the first portion, a distal portion coupled with and extending away from the tuberosity portion.
Claims9
A slot anchor guide, comprising:
- a medial portion and a lateral portion;
- the medial portion comprising an oval shaped medial projection wherein the medial projection is configured to mate with an oval shaped slot of a fixation plate establishing an interference fit such that the fixation plate is held on the slot anchor guide and the slot anchor guide can be used to manipulate the fixation plate;
- wherein the slot anchor guide is configured to guide an anchor through a predetermined position in the slot of the fixation plate and to mate with the fixation plate to allow the fixation plate to be configured to engage a bone surface by manipulating the lateral portion;
- and
- wherein the lateral portion includes an elongate cylinder that projects between a terminal lateral end of the slot anchor guide and the medial portion and a lumen therethrough the elongate cylinder that extends from the terminal lateral end through the lateral portion to an arched opening adjacent to the medial portion.
An assembly comprising:
- a slot anchor guide that comprises:
- a medial portion and a lateral portion;
- the medial portion comprising an oval shaped medial projection wherein the medial projection is configured to mate with an oval shaped slot of a fixation plate establishing an interference fit such that the fixation plate is held on the slot anchor guide and the slot anchor guide can be used to manipulate the fixation plate;
- wherein the slot anchor guide is configured to guide an anchor through a predetermined position in the slot of the fixation plate and to mate with the fixation plate to allow the fixation plate to be configured to engage a bone surface by manipulating the lateral portion;
- the fixation plate comprising an anchor aperture and the slot;
- a drill sleeve comprising an elongate cylinder and a lumen disposed therethrough, the drill sleeve including threads disposed on an external surface of a medial portion thereof;
- and
- an anchor trajectory guide that includes a guide groove located in an inferior terminal end and configured to receive a curved free end of the superior-inferior projection of the slot anchor guide so that the slot anchor guide and the anchor trajectory guide nest together when mated to the fixation plate;
- wherein the slot anchor guide can be secured to the fixation plate by engaging the threads of the drill sleeve with threads of the anchor aperture through a superior-inferior projection of the slot anchor guide.
