An orthopedic implant screw driver includes drive shaft. A first gear is operably coupled to the drive shaft and in meshing engagement with a hollow gear which rotates in response to rotation of the drive shaft. The hollow gear includes a passage defining an inwardly facing screw engagement periphery configured to receive and drivingly rotate a threaded portion of the screw. A method of securing an orthopedic implant to a bone includes positioning a screw within the passage which is configured to drivingly engage a threaded portion of the screw and rotating a drive shaft in driving engagement with the gear causing the gear to engage the screw along the threaded portion of the screw and rotatably drive the screw via the threaded portion.

Screw driver, combination, and related methods

The present teachings provide one or more surgical implements for repairing damaged tissue, such as in the case of a spinal fixation procedure. A cross connector system for use during a spinal fixation procedure is provided. The system includes at least one bridge defining a coupling bore and having a pair of downwardly extending arms for coupling to a first fastener. The system includes a contoured bar having a first end offset from a second end, and a bore having a central axis. The system includes an expansion ring received within the bore, and a locking device received through the expansion ring and the coupling bore. The locking device is operable in a first state in which the contoured bar is movable about the central axis of the bore and in a second state in which the contoured bar fixed relative to the central axis of the bore.

Curved spacer and inserter

An apparatus for measuring a distance between first and second implanted bone anchors includes a caliper body and first and second caliper arms. The caliper body has a first longitudinal axis. The first caliper arm is slidably coupled to the caliper body and has a second longitudinal axis. The second caliper arm is rotatably coupled to the caliper body and has a third longitudinal axis. The first, second and third longitudinal axes define a plane. The second caliper arm is rotatable within the plane between a first position and a second position.

Apparatus and method for measuring a length between implanted bone anchors

The present teachings provide an implant. The implant can include an implant body partially defining at least one threaded aperture. The implant can also include a bone fastener including a threaded portion threadably engaged with the at least one threaded aperture. The threaded aperture can circumferentially surround no more than 180&#xb0; of the bone fastener.

Implant with semi-enclosed screws

An expandable spinal implant device for supporting vertebral bodies can include first and second body members and first and second expansion mechanisms. The body members can each have a first end positionable toward one of the vertebral bodies and can each define a hollow interior. The expansion mechanisms can be spaced apart from each other and can include a first drive shaft and a second drive shaft, respectively. The first and second drive shafts can each have a gear member fixedly coupled thereto. Each drive shaft can be threadably engaged at a first side to the first body member and at a second side to the second body member. The expansion mechanisms can be operable to effect axial displacement of the first body member relative to the second body member by rotationally driving the gear members of the first and second drive shafts.
