摘要:
A tissue extender includes a ring defining a proximal end opening to engage a head of a subcutaneous screw, a first extender portion coupled to the ring at a proximal end of the first extender portion, and a second extender portion coupled to the ring at a proximal end of the second extender portion. The first extender portion includes a first coupling portion disposed at a distal end of the first extender portion, and the second extender portion includes a second coupling portion at a distal end of the second extender portion. The first and second extender portions define two side openings disposed on opposite sides of the tissue extender. The distal ends of the first and second extender portions together define a distal end opening. The first coupling portion engages the second coupling portion when the tissue extender is in an extended state. The distal end opening is larger in the extended state than in an unextended state.

摘要:
A method of conducting a surgical procedure including implanting an anchor into a bone, wherein the anchor comprises a receiving portion and a screw, the screw including a screw head contained within the receiving portion and pivotally engageable with a surface of the receiving portion, and wherein the receiving portion and the screw comprising a different material. The method further includes selecting a rod from a group of rod types and coupling the rod with the receiving portion to stabilize a position of a portion of the spine.

A spinal correction system comprises an elongate member extending between a first end including a first inner surface defining a first cavity and a second end including a collar having a second inner surface defining a second cavity. The second cavity is movable relative to the elongate member in at least one orientation. The second end defining an elongated cavity. A first extender defines a first outer surface and a second extender defines a second outer surface. The elongate member is disposable between a first configuration and a second configuration such that the second cavity is movable in the at least one orientation to a position such that the first inner surface is forcibly disposable in a fixed engagement with the first outer surface and the interior surface is forcibly disposed in a fixed engagement with at least a portion of the collar. Methods of use are disclosed.
摘要:
An adjustable vertebral body elevator is disclosed and can include a handle and a spoon rotatably coupled to the handle by a locking assembly. The handle can rotate with respect to the spoon around an axis or rotation. Further, the locking assembly can be coaxial with the axis of rotation.

Derotation instrument assemblies and systems are provided to facilitate positioning one or more vertebrae of a spinal column into a desired alignment. The instrument assemblies and systems include implant holders engageable to respective implants engaged to vertebrae of the spinal column, transverse bridges to connect implant holders associated with a particular vertebra, and inter-level linking assemblies to connect instrument assemblies associated with different vertebrae. Derotation handles can be provided on the implant holders to facilitate application of the alignment forces, while the assemblies distribute the corrective forces to the connected implants and vertebrae.
摘要:
A staple for stabilizing the attachment of a vertebral screw and a longitudinal member to the spine. The staple has a plate with first and second apertures. All the staple's legs, prongs, or spikes attached to the underside of the staple are located closer to one particular aperture than the other. Preferably, the plate is also “bow-tie” shaped with a groove that separates the wings of the bow-tie. This bow-tie or hour glass shape combined with the groove help the surgeon to more easily conform the plate to the patient's vertebra.
