Abstract
Orthopedic fixation devices and methods of installing the same. The orthopedic fixation device may include a coupling element and a bone fastener, whereby the bone fastener can be loaded into the coupling element through the bottom of a bore in the coupling element.
Claims18
A method of installing an orthopedic fixation device comprising:
- inserting a locking clamp assembly into a bore in a coupling element, wherein the locking clamp assembly comprises a wedge element and a clamp element secured to the wedge element;
- moving the locking clamp assembly through the bore in the coupling element until a recessed surface on the wedge element engages a protuberance on an interior surface of the coupling element to secure the locking clamp assembly in the coupling element;
- inserting a head of a bone fastener into the clamp element such that the clamp element engages the head;
- and
- moving the wedge element downward past the protuberance on the interior surface of the coupling element such that exterior surfaces of the clamp element engage the interior surface of the coupling element forcing the clamp element to clamp onto the head of the bone fastener to secure the bone fastener in the coupling element.

A method of installing an orthopedic fixation device comprising:
- implanting a bone fastener into a vertebrae;
- securing the bone fastener to a tulip element, the tulip element containing a locking clamp assembly within a bore in the tulip element, wherein the locking clamp assembly comprises a wedge element and a clamp element secured to the wedge element, wherein a recessed surface on the wedge element engages a protuberance on an interior surface of the tulip element to secure the locking clamp assembly in the tulip element;
- rotating the tulip element to a desired position with respect to the bone fastener;
- and
- locking the position of the tulip element relative to the bone fastener by moving the wedge element downward past the protuberance on the interior surface of the tulip element such that exterior surfaces of the clamp element engage the interior surface of the tulip element forcing the clamp element to clamp onto the bone fastener.
