Abstract
Bone implants, assemblies, and methods thereof. The implants may include non-threaded triangular implants configured to promote fixation and fusion of the sacroiliac joint. The implants may have a triangular body configured to prevent or minimize rotational motion of the implant. The implants may include an inner core or an outer shell, which provides structural support for a lattice structure. The structural geometry may be generated through topology optimization software, such as finite element analysis, based on anatomical loading conditions for the implant.
Claims20
An SI joint fusion implant comprising:
- a dowel extending along a central longitudinal axis having a distal tip configured to facilitate insertion into bone for fusing the SI joint and a proximal end configured to be engaged by an insertion instrument, the dowel having a triangular cross-section with three faces and three vertices configured to limit rotational motion about the central longitudinal axis;
- wherein the dowel includes a solid portion for providing structural integrity and a porous lattice portion for facilitating bone growth;
- wherein the distal tip includes a plurality of tapered planar surfaces that meet at the distal end of the implant.
