摘要: This invention relates to methods and instruments for performing a surgical procedure in a disc space between adjacent vertebrae. The instruments include a distractor and a cutting instrument. In one embodiment the distractor includes a body portion and a pair of flanges extending along opposite sides of the body portion such that a slot is formed between the flanges and the body portion. The cutting instrument is positionable over the body portion and into the slots of the distractor so that the flanges are positioned between the cutting instrument and the adjacent tissue.

摘要: A method and instrumentation for spinal interbody fusion is disclosed. The instruments and methods are particularly adapted for interbody fusion from a posterior approach to the spine. One instrument is a retractor having a lockable pivotally mounted handle. Another instrument is a template for straddling the dura. A modular distractor is also provided and preferably includes a tapered shaft with a visualization window disposed therein. Yet another instrument is a depth gauge to verify bone opening depth and dimension, preferably including a radiopaque portion. A method contemplates the use of these instruments to prepare a disc space to receive an implant.

摘要: An osteogenic material packing device is used to pack osteogenic material onto a spinal fusion device. The packing device has a cavity defined therein, which is adapted to receive the spinal fusion device. The packing device further includes an access port, which intersects the cavity to receive the osteogenic material. A cannula is coupled to the packing device and an inserter is coupled to the fusion device in order to insert the fusion device into the packing device. Osteogenic material is packed through the access port around the fusion device. The fusion device then is slid through the cannula and inserted in the intervertebral space between adjacent vertebrae.

摘要: This invention relates to methods and instruments for performing a surgical procedure in a disc space between adjacent vertebrae. A cannula is inserted to create a working channel through the skin and tissue of a patient using a transformational approach to the disc space. A viewing element is used to visualize working end of the cannula and the disc space. A facetectomy is performed through the working channel to access the disc space. The disc space is prepared with various instruments, such as distractors, shims, chisels and distractor-cutters that extend through the working channel. At least implant is inserted into the disc space. The procedure allows bi-lateral support of the adjacent vertebrae with the at least one implant inserted via a unitary, minimally invasive approach to disc space.

摘要: This invention provides a vertebral implant for impaction in a disc space to restore and/or maintain desired disc space height and spinal orientation. The implant has an elongated basis body having a generally lens-shape provided by convex upper and lower surfaces. Bearing surfaces are provided on the cross-edge surfaces of the endwalls. Grooves are provided in the upper and lower surfaces positioned between the bearing surfaces. The implant can be prepared from a wide variety of materials including metallic materials, synthetic materials, polymeric materials, ceramic materials, and composite materials including reinforced materials i.e. glass, fiber, and/or carbon fiber reinforced materials (CFRP). These preferred materials for fabricating implants in the present invention reduce costs, increase service life and provide excellent physiological compatibility. The non-metallic material can be selected to be either a substantially permanent material, a biodegradable material or a bioerodable material. Further, the implant material can be provided to be radio opaque to facilitate monitoring of bone ingrowth both into the implant and between the opposing endplates of the adjacent vertebrae.

摘要: This invention relates to intervertebral spacers for use in orthopedic treatment of spinal defects. The intervertebral space is formed of a shaped memory polymer material. The spacer can be fabricated into a desired configuration and then deformed into an alternative or deformed configuration. Cooling the deformed spacer effectively freezes the spacer into its deformed conformation. The deformed configuration can be selected to facilitate implantation of the spacer into a prepared disc space between adjacent vertebrae. During operation, the surgeon can heat the spacer to allow it to revert to its original configuration. The spacer in its original conformation is sized to restore and/or maintain the adjacent vertebrae in a desired conformation and disc space height.

摘要: A percutaneous surgical system includes a plurality of tissue retractors configured to maintain a working space within soft tissue. The tissue retractors include a prong on their inner surfaces for engaging a ring member. The ring member maintains the position of the tissue retractors while also defining a number of channels inside the ring member. In one embodiment, the ring member includes concentric inner and outer walls connected by support walls. The inner wall defines an inner bore for supporting a working channel sleeve for the introduction of working instruments. A plurality of outer channels are defined between the inner, outer and support walls for the introduction of ancillary instruments to the surgical site. A manipulation tool is also provided that engages each tissue retractor for positioning the retractor within the patient.

摘要: A plate of biocompatible material is provided having curvature in two planes such that it conforms to the curvature of the L5 vertebral body and to the patient's lordotic curve. Holes are provided receiving screws for anchorage in the vertebral body and sacrum. A flange or foot portion on the plate provides a wider base end area for support in the L5-S1 interspace. The foot portion is also arranged for appropriate entry angle of screws into the sacrum such as to improve anchorage in the sacrum. Anti-backout and low profile features are incorporated. The anterior lumbar plate is situated to maintain the anterior interbody bone graft in compression by resisting tensile forces during extension.
