Method and system for attaching a plate to a bone
A guide tool having a through bore and at least one distal locating feature is provided. The distal locating feature of the guide tool is placed into a predetermined relationship with the plate. A fastener is engaged with a distal end of a driver shaft of a fastener driver. The fastener driver has a driver orientation means associated with the driver shaft. The fastener is inserted into the through bore of the guide tool with the fastener driver. The driver orientation means is mated with a guide orientation means located in the through bore of the guide tool. At least a portion of the fastener is inserted through the fastener hole. The fastener is secured into the bone through actuation of the fastener driver. The fastener driver is withdrawn from the guide tool, which is withdrawn from the plate.
1. A system for attaching a plate to a bone, the system comprising:
a plate having at least one fastener hole extending from a proximal face of the plate and through a plate body to a distal face of the plate;
a fastener;
a guide tool having a through bore defining a longitudinal axis therethrough, a guide orientation means located in the through bore, and at least one distal locating feature, the distal locating feature being selectively placed in a predetermined contacting relationship with the plate to place the guide tool in a particular orientation with respect to the plate;
a fastener driver having a driver shaft and being adapted to engage the fastener for insertion into the through bore of the guide tool, the fastener driver having a driver orientation means associated with the driver shaft, the driver orientation means being a stud-type protrusion adapted for mating with the guide orientation means; and
an elongated plate holder having a distal end adapted for insertion and frictional engagement with the fastener hole, the plate holder being manipulable to move the plate into a desired placement with respect to the bone, and wherein the plate holder is adapted for at least partial insertion into the through bore of the guide tool;
wherein at least a portion of the fastener is inserted through the fastener hole with the fastener driver, the fastener driver being actuatable to secure the fastener into the bone;
wherein the distal locating feature remains in contact with the plate during at least a portion of the insertion of the fastener into the bone; and
wherein a predetermined fastener rotational insertion orientation with respect to the longitudinal axis of the guide tool is guided through the mating of the stud-type protrusion and the guide orientation means when the guide tool has achieved the particular orientation with respect to the plate via placement of the distal locating feature in the predetermined contacting relationship with the plate.
