An anchor assembly for use in spinal fixation to interconnect a longitudinal spinal rod with a patient's vertebra. The anchor assembly preferably includes a bone anchor, a body with a rod-receiving channel, an insert member (preferably a bushing), and a locking cap. The anchor assembly enables in-situ assembly where the bone anchor may be secured to the patient's vertebra prior to being received within the body of the bone anchor assembly. Accordingly, the anchor assembly enables a surgeon to implant the bone anchor without the body to maximize visibility and access around the anchoring site. Once the bone anchor has been secured to the patient's vertebra, the body may be snapped onto the bone anchor and a spinal rod may be inserted into the rod-receiving channel.

Bone fixation assembly

A spine derotation system includes bone fixation elements, fixture members, clamps and stabilizers. The clamps can collectively lock together multiple proximal ends of bone fixation elements extending from one lateral side of the spine. The stabilizers may include clamp stabilizers that are configured to couple together two or more clamps to each other so as to facilitate derotation and alignment of multiple vertebrae of a patient's spine. The stabilizers may also include fixture stabilizers that are configured to couple together two fixture members on the same vertebra to facilitate derotation.

Spine derotation system

A reduction tool for use in posterior spinal fixation to facilitate insertion of a longitudinal spinal rod into a rod-receiving channel formed in a bone fixation element. The reduction tool preferably includes an outer tube sized and configured to transversely receive the spinal rod therethrough, the outer tube being operatively coupled to the bone fixation element, an inner tube operatively coupled to a locking cap and slidably disposed within the outer tube, and a rotatable sleeve for rotatably advancing the inner tube with respect to the outer tube to advance the spinal rod into the rod-receiving channel formed in the bone fixation element and to couple the locking cap to the bone fixation element to thereby secure the rod within the bone fixation element.
