Abstract
Bone anchor implants, assemblies, systems, instruments, and methods thereof. The bone anchors may be threaded or non-threaded, adjustable or expandable, stackable, or otherwise configured to promote fixation of the sacroiliac joint. The bone anchors may be used independently or may be configured to integrate with long rod constructs, for example, with a tulip or other suitable attachment interface, to fuse the sacroiliac joint.
Claims8
A sacroiliac joint fixation implant comprising:
- an outer sleeve and an inner sleeve extending along a central longitudinal axis, the outer sleeve defining a central channel for receiving the inner sleeve, the inner sleeve defines an opening configured for receiving a spinal rod, and the inner sleeve includes an inner tapered section around the opening;
- a clamp receivable through the inner sleeve, the clamp having a clasp configured for receiving the spinal rod;
- and
- a tightening bolt coupled to the clamp, wherein as the tightening bolt is rotated, the clamp is drawn back proximally into the tightening bolt, and the clasp is retracted into the inner tapered section, thereby locking the spinal rod to the implant,
- wherein the tightening bolt is partially cannulated with a blind hole and a proximal end of the clamp is received therein.
