In accordance with one aspect, a spinal implant for fusing vertebral bones is provided that includes a monolithic body for being inserted between bones. The body has a through opening of the body for receiving bone growth material and a wall of the body extending about the through opening. The wall includes nubs extending into the through opening that increase the surface area of the wall available for bone on-growth.

Intervertebral implants, instruments, and methods

In one aspect, a bone anchor assembly is provided having a bone anchor with a head, a resilient locking cap extending about a portion of the bone anchor head, and a cap drive member having a depending annular wall. In another form, a bone plate system is provided including a bone plate having an elongated throughbore and a resilient support member received therein. In another aspect, an insertion device is provided for manipulating and inserting a spinal device at or within a spinal joint. The insertion device is configured to actively pivot the implant about the implant gripping end of the device and to allow manipulation and release of the implant in any pivoted orientation from approximately 0 to 90 degrees.

Instrument for inserting a spinal device

Methods and apparatus for immobilizing a synovial joint, such as a sacroiliac (SI) joint are disclosed. In one form, a multipiece fixation device, such as a dowel, includes multiple expandable fasteners that are configured to fix adjacent bones of a synovial joint with respect to one another. The expandable fasteners include expansion portions that are expanded radially via insertion of another expandable fastener or an expansion device to fix the expandable fasteners to the bone. The fixation device may be configured to provide for compression or distraction of the bones of the synovial joint while at the same time stabilizing the joint.

Apparatus for immobilization and fusion of a synovial joint

In accordance with one aspect of disclosure, an inserter tool is provided for an elongate intervertebral implant. The inserter tool includes a body and a distal end portion of the body configured to be connected to the elongate intervertebral implant to orient the elongate intervertebral implant so that a longitudinal axis thereof extends in a predetermined direction. The inserter tool includes an offset member extending from the body. The offset member has an impact surface support portion spaced apart from the body and configured to position an impact surface in alignment with the implant longitudinal axis to permit the impact surface to receive an impact force directed in the predetermined direction.

Intervertebral implant inserter tool

Intervertebral implant

An implant device is provided that is configured for implantation at multiple locations between adjacent vertebrae. The implant device comprises an implant body, a first portion of the implant body, and a second portion of the implant body adjustably interconnected with the first portion. The implant body has a compact orientation and an extended orientation to allow the implant body to be shifted from one orientation to the other orientation for being positioned in any one of areas between the spinous processes of the adjacent vertebrae, between laminar regions of the adjacent vertebrae, spanning an opening in the annulus between the adjacent vertebrae, and in the intervertebral space between the adjacent vertebrae.

Intervertebral implant devices and methods for insertion thereof

Apparatus and methods for immobilization and fusion of a synovial joint

Systems and tools for inserting and securing an implant within the intervertebral space. An intervertebral disc implant with upper and lower bearing members with an articulation interface between the members for providing relative motion therebetween. The implant may be provided with various securing members for fixing the implant within the intervertebral space. A tool may be used to insert the implant, which includes a plurality of shiftable implant engaging members that are shiftable between non-engaging and engaging configurations to alternatively release or hold the implant.

Intervertebral disc implant

An artificial disc device for replacing a damaged nucleus is disclosed. In one form, the device may be inserted in components such that the device may be assembled within and retained by the natural annulus therein. In another form, the device may be inserted into the natural annulus in a collapsed or compressed state or arrangement and then be expanded within and retained by the annulus therein. In a further form, the device may be provided with a releasable connection so that the device may be connected in an insertion configuration and may be released in an operable configuration. Insertion tools and methods are also disclosed.
