Bone implants, including methods of use and assembly. The bone implants, which are optionally composite implants, generally include a distal anchoring region and a growth region that is proximal to the distal anchoring region. The distal anchoring region can have one or more distal surface features that adapt the distal anchoring region for anchoring into iliac bone. The growth region can have one or more growth features that adapt the growth region to facilitate at least one of bony on-growth, in-growth, or through-growth. The implants may be positioned along a posterior sacral alar-iliac (SAI) trajectory. The implants may be coupled to one or more bone stabilizing constructs, such as rod elements thereof.

A system for performing a fusion procedure on a sacroiliac joint defined between a sacrum and an ilium. The system may include a working cannula including a proximal end, a distal end, a tubular body extending between the proximal and distal ends, a cannula passageway defined within the tubular body and having a cannula axis extending there through, a pair of prongs coupled to the tubular body and extending distally there from, an anchor arm engagement structure coupled to the tubular body, and a pin guide coupled to the tubular body and defining a pin passageway having a guidance axis there through that is generally parallel with the cannula axis.

A bone screw comprises a main body including a shank portion, a head portion attached to the shank portion, and a cap moveably attached to the head portion. The head portion includes a tool interface structure therein having a closed end portion, an open end portion and sidewall extending therebetween. A tool lock recess is provided in at least one of the sidewalls of the tool interface structure. The tool interface structure is accessible through an opening within an exterior surface of the cap.

The present invention relates to a method of inserting an implant comprising providing an expandable vertebral implant. The method further may comprise providing an angling inserter tool. The angling inserter tool comprises a handle portion, a base portion, and a tip assembly, the base portion being disposed between the handle portion and the tip assembly. The method further may comprise distally advancing a central shaft of the tip assembly with rotation into an opening in the expandable vertebral implant to secure the angling inserter tool to the expandable vertebral implant. The method further may comprise positioning the expandable vertebral implant in a patient's spine. The method further may comprise for causing the tip assembly to angulate with respect to a longitudinal axis of the angling inserter tool, wherein the internal shaft is coaxial with an outer cylinder of the base portion.

An expandable screw for orthopedic insertion and expansion between a collapsed state and an expanded state. The screw has an upper externally-threaded body segment, a lower externally-threaded body segment opposite the upper external thread segments, and an expansion member extending along a longitudinal axis thereof. The expansion member connecting the upper externally-threaded body segment to the lower externally-threaded body segment, and configured during the expansion between the collapsed state and the expanded state to separate the upper externally-threaded body segment from the lower externally-threaded body segment.

A disc replacement device including a first body member with a convex articulation surface and a second body member with a concave articulation surface is disclosed. When operably positioned, the convex articulation surface engages the concave articulation surface to provide for movement therebetween. The disc replacement device also includes a first opening in the first body member and a second opening in the second body member, wherein the openings are angled and extends from the front aspects of the body members through the external surfaces. The disc replacement device further includes at least two bone fasteners for insertion into the first and second openings to secure the disc replacement device to a first and second vertebra. An interbody motion device and fusion implant, as well as a surgical method for implantation are also disclosed.

A subtalar joint implant system that includes a first implant component and a second implant component is disclosed herein. An alternative embodiment of a subtalar joint implant system is disclosed and includes a first component that has threads disposed on at least a portion of an exterior surface of the first component and a second component having threads disposed on at least a portion of the exterior surface of the second component. The first and second components are each configured to couple with at least a portion of a talus and a calcaneum of a patient with the first component being configured to couple with at least a portion of a posterior facet of the calcaneum of the patient and the second component being configured to couple with at least a portion of a middle facet of the calcaneum of the patient.
