A multi-piece intervertebral disc augmentation implant that may be assembled within the annulus fibrosus is disclosed. The implant may be guided into a precise location through a relatively small opening in the annulus fibrosus with the aid of an elongated guide.

A spacer for inserting between vertebral members. The spacer has a non-spherical shape with an anterior section having a first shape and a posterior section having a different shape. An attachment means is positioned within the posterior section, and may include a receiver for attachment with an insertion device, and an anti-rotation mechanism for assistance in removing the spacer from the insertion device. Embodiments of using the spacer is also disclosed which may include inserting the spacer between the vertebral members in a generally posterior approach. Once inserted, the insertion device acts with the anti-rotation device to remove a connection mechanism from the receiver. The spacer remains between the vertebral members and provides relief to the patient.

An intervertebral fusion device for promoting fusion of first and second vertebrae comprises first and second endplate modules. Each endplate module includes an outer surface adapted to interface with vertebral bone and an opposite inner surface. The endplate modules further include an attachment feature. A central module is adapted to extend between the first and second endplate modules and is further adapted for connection with the attachment feature. A through passage extends through the outer and inner surfaces of the each of the first and second endplates and through the central module.

A surgical staple inserter is disclosed and can include a shaft and a staple engagement arm pivotably engaged with the shaft. Further, the surgical staple inserter can include a spring that can be connected to the shaft and the staple engagement arm. The surgical staple inserter can be moved between a straight position and a bent position. In the straight position, the staple engagement arm can be substantially aligned with the shaft. In the bent position, the staple engagement arm can be rotated with respect to the shaft.

A surgical tool and method are provided for positioning an intervertebral device between vertebral members. The tool includes an elongate shaft, an anti-rotation sleeve, and an actuation mechanism. The shaft has proximal and distal ends, with the distal end of the shaft including an engagement member for releasably engaging an intervertebral device. The sleeve includes proximal and distal ends, and is movably mounted to the shaft for reciprocating relative thereto between retracted and extended positions. The distal end of the sleeve includes an anti-rotation member. The actuation mechanism controls positioning of the sleeve between the retracted and extended positions, and locks the sleeve relative to the shaft. When the intervertebral device is releasably engaged by the engagement member, and the sleeve is in the extended position, the anti-rotation member engages the intervertebral device and prevents rotation of the intervertebral device when releasing the engagement member from the intervertebral device.
