An implant and method for fusing adjacent spinal vertebrae is disclosed. In an embodiment for a spinal implant of the present invention, the implant includes a spacer body assembly and two retention members. The two retention members each include split fork tangs wherein the tangs of each retention member are simultaneously extendable from the spacer body assembly into the adjacent vertebra. A method of fusing adjacent vertebrae includes the step of inserting an implant between adjacent vertebrae with retention members. The method also includes the step of configuring the retention members wherein a portion of each tang of a retention member simultaneously extends from the implant into one of the adjacent vertebra.

A bone graft delivery system and method for using same to deliver graft material into a surgical site. The system includes an interbody implant having a securing site disposed on a surface of the implant and a holder having an elongated, hollow handle including a distal end. The distal end of the holder is configured to removably engage the securing site of the interbody implant to secure the interbody implant to the distal end of the holder until such time as a user desires to disengage the holder from the interbody implant. The interbody implant may be a cage implant having opposing anterior and posterior surfaces, opposing first and second lateral surfaces, and opposing top and bottom surfaces, wherein the top surface comprises a first aperture and the bottom surface comprises a second aperture, the posterior surface comprising a third aperture, the first, second, and third apertures all linking to a main cavity, the main cavity generally extending between the top surface and the bottom surface.

Devices, systems and methods for surgical treatment of mid-foot disorders such as osteoarthritis, spacing disorders, or alignment disorders, including mid-foot arthroplasty devices and systems for the 2.sup.nd and 3.sup.rd tarsometatarsal (TMT) joint, implants for post-osteotomy spacing and + realignment, arthroplasty articular implants, dowel grafts for TMT arthrodesis or fusion, dowel grafts for navicular cuneiform (NC) arthrodesis, dowel grafts for intercuneiform arthrodesis, and/or locking dowels for joint fusion.

An apparatus including a humeral anchor configured to be mounted to a humerus and configured to receive a humeral component; wherein the humeral anchor includes a central hub having a plurality of fins extending therefrom, wherein the plurality of fins are arranged in an asymmetric pattern.

An expandable implant includes an upper main support, a lower main support, an upper pivoting support, and a lower pivoting support. The upper main support and the upper pivoting support are configured to engage a first portion of bone, and the lower main support is coupled to the upper main support and configured to engage a second portion of bone. The upper main support is adjustable relative to the lower main support to adjust height of the implant. The upper pivoting support is rotatably movable relative to the upper main support. The lower pivoting support is coupled to the upper pivoting support, configured to engage the second bone portion, and is rotatably movable relative to the lower main support. Adjusting the upper main support relative to the lower main support causes adjustment of the upper pivoting support relative to the lower pivoting support.

Novel implants, instruments and surgical techniques are provided for manipulating a spinal disc space in order to one or more of: optimize disc space preparation; optimize the positioning of implants within the disc space; achieve and maintain distraction during interbody placement; and provide sagittal balance during fusion.

An implant for use in a spine includes a body and a plurality of structural members. The plurality of structural members includes outer members that are arranged to contact a vertebra upon implantation and support members that provide reinforcement and stability to the outer members. The outer members may have sections with a generalized helical geometry. The generalized helical geometry provides distal and proximal outwardly facing surface regions and creates a series of protected fusion zones along the superior and inferior surfaces of the implant to foster adjacent bone growth.

A method of fusing a sacroiliac joint including a sacrum, an ilium, and a sacroiliac joint space defined therebetween. The method may include: approaching a posterior aspect of the sacroiliac joint space with a joint implant including a body extending a length between a distal end and a proximal end; and delivering the joint implant into the sacroiliac joint space such that the joint implant passes through an access region defined between the posterior superior iliac spine and the posterior inferior iliac spine. The joint implant may be oriented in the sacroiliac joint space such that a portion of the body of the joint implant is positioned within a joint plane of the sacroiliac joint space, and such that the distal end of the joint implant is positioned posteriorly of an anterior boundary of the sacroiliac joint space.
