An expandable spinal implant includes a distal projection extending from only one side of the implant, ending in an anterior tip, the anterior portion and anterior tip defining an elongated distal end hook, which is wider than the proximal end. The distal end hook rotates around the spinal cord, aligning the implant with a desired pathway, then inserts into place in the disc space between the vertebrae. The elongated widened distal end hook provides a TLIF approach, distributes loads, provides anterior rim engagement, and creates lordosis.

Expandable spinal implant system and method of using same

A surgical instrument comprises a member being engageable to a spinal implant configured for connection to a bone fastener shaft. An actuator is connected to the member. A latch is connected to the actuator and the connection is configured to change between at least one non-locked orientation such that the actuator is movable relative to the member and a locked orientation such that the actuator is fixed relative to the member. Systems, spinal constructs, implants and methods are disclosed.

Surgical instrument and method

Expandable spinal implant system with a biased tip and method of using same

A surgical instrument having a first member engageable with a first end of a fastener having a second end configured to penetrate tissue. A second member includes an expandable member configured for engaging the first end. Systems and methods are disclosed.

A method for treating a spine is provided. The method includes the steps of: disposing an interbody implant adjacent a posterior portion of an intervertebral disc space; connecting a surgical instrument with at least one fixation element fastened with tissue adjacent the posterior portion; and manipulating the surgical instrument such that tissue adjacent the posterior portion engages the interbody implant and one or more vertebra rotate about the interbody implant. Spinal implants; surgical instruments and systems are disclosed.

Spinal implants, surgical instruments and systems are disclosed.

A method for treating vertebrae comprises the steps of: connecting at least one fastener with portions of vertebrae; providing a fastener comprising a first portion including a receiver defining an implant cavity and a member disposable with the implant cavity and movable relative to the receiver, and a second portion defining a longitudinal axis and being configured to penetrate vertebral tissue, wherein the receiver is non-pivotable relative to the longitudinal axis and connecting the fastener to the vertebrae; providing a longitudinal element; connecting a first portion of the longitudinal element with the at least one fastener; derotating the vertebrae to a selected orientation; and connecting a second portion of the longitudinal element with the fastener to substantially maintain the vertebrae in the selected orientation. Systems are disclosed.

Spinal correction system and method

An instrument is provided for reduction of a rod or other elongated member into an implant, such as a bone screw. In one embodiment, such an instrument includes a rod adjusting assembly pivotably attached to an implant holding assembly. The implant holding assembly can be pivotably connected to an implant, and the rod adjusting assembly is operable to move a rod toward or away from the implant holding assembly. In that embodiment, several motions are possible by the instrument so that relatively small or large movements of a rod with respect to an implant may be made.

Reducing instrument for spinal surgery

Embodiments of the invention include implants and methods for connecting devices to bones, such as one or more endplates of vertebrae. Devices may include mechanisms for connecting to one or more vertebrae by extending portions of the devices through an aperture in a vertebral implant and expanding the implant within the one or more vertebrae. A fill material may be used to drive the expansion in some embodiments.
