Spinal implant

A spinal implant may be used to stabilize a portion of a spine. The implant may promote bone growth between adjacent vertebrae that fuses the vertebrae together. An implant may include an opening through a height of a body of the implant. The body of the implant may include curved sides. A top and / or a bottom of the implant may include protrusions that contact and / or engage vertebral surfaces to prevent backout of the implant from the disc space. A variety of instruments may be used to prepare a disc space and insert an implant. The instruments may include, but are not limited to, a distractor, a rasp, and one or more guides. The implant and instruments may be supplied in an instrument kit.

Instruments and methods for adjusting separation distance of vertebral bodies with a minimally invasive spinal stabilization procedure

A spinal stabilization system may be formed in a patient. In some embodiments, a minimally invasive procedure may be used to form a spinal stabilization system in a patient. Bone fastener assemblies may be coupled to vertebrae. Each bone fastener assembly may include a bone fastener and a collar. Extenders may be coupled to the collar to allow for formation of the spinal stabilization system through a small skin incision. The extenders may allow for alignment of the collars to facilitate insertion of an elongated member in the collars. An elongated member may be positioned in the collars and a closure member may be used to secure the elongated member to the collars. An adjuster may be used in conjunction with the extenders to change a separation distance between the bone fastener assemblies.

Artificial spinal disc, insertion tool, and method of insertion

An artificial spinal disc is provided for unilateral insertion from the posterior side of the patient and includes a pair of plate members with a bearing associated with one plate member and a depression associated with the other for permitting limited flexibility of patient movement. An outrigger is provided which includes rods extending through the pedicles on one side of each of two adjacent vertebrae and posts connected to the rods which provide an artificial facet joint. A method of insertion of the artificial spinal disc hereof includes cutting channels for receiving longitudinally extending ribs on the plate members and removing the natural facet joint in order to permit insertion of the artificial spinal disc. A tool for insertion of the artificial spinal disc acts as a drill guide for creating a passage through the pedicles.

Packable ceramic beads for bone repair

Adherent packed beds of ceramic beads, each comprising a ceramic body coated with a biodegradable polymer, and fabric bags containing such beads in a packed, self-supporting configuration. The polymeric coating provides some resilience to a packed bed of the ceramic beads, and prevents the beads from moving with respect to each other when placed under stress, leading to reduced breakage. The ceramic beads desirably are osteoconductive, and preferably are formed of a ceramic material that is resorbed during bone growth, such as hydroxyapatite, tricalcium phosphate, or mixtures of these materials. The beads may contain, either internally or on their surfaces or both, a bone morphogenic protein, and the latter may also be included in the biodegradable polymer coatings on the beads.

Expandable spinal implant apparatus and method of use

ActiveUS20100286779A1Decrease patient riskIncrease success rateBone implantSpinal implantsEngineeringCam
A spinal implant apparatus that is an expandable spacer including features to minimize or eliminate spacer cant or offset during and after completing the expansion process. The spacer includes a top component, a base component in engagement with the top component, and an expansion mechanism arranged to change the top component's position with respect to the base component. The mechanism for causing expansion may be a screw, a cam, a wedge or other form of distracting device. In one embodiment, the expandable spacer includes a base component with a set of towers and a top component with a set of corresponding silos, where the towers and silos are configured to minimize or eliminate tilt of the top component as it extends upwardly from the base component. In another embodiment, the spacer may include a stepped arrangement around the perimeter of the top component and the base component for engagement during height expansion with minimal canting or slippage. In another embodiment, the spacer may include texturing modification at the opposite ends of the longitudinal axis of the spacer to prevent tilting, slipping, or canting. Additionally, a portion of one or more exterior surfaces of the spacer may be textured, sawtoothed, dovetailed or the like to increase frictional intervertebral contact. The spacer may contain one or more passageways of selectable shape / dimension for bone growth through the spacer.

Pedicle screw with expansion anchor sleeve

A bone anchor for use in conjunction with orthopedic spinal fixation comprising a pedicle screw having a threaded proximal tip for threaded insertion into a hole prepared into a vertebral body through the pedicle of the vertebra from the posterior approach. The shank of the anchor is of smaller diameter than the proximal tip so as to receive a sleeve after insertion into the bone. The tubular sleeve is provided with a plurality of longitudinal slots evenly arranged about the longitudinal axis of the sleeve to forming a plurality of longitudinal. A tubular compression collar for insertion over said shank portion is provided on the shank and driven toward the proximal tip compression the sleeve and causing the ribs to expand radially into a star pattern securing the anchor in the bone. A tubular collar of natural or synthetic bone growth promoting material may be inserted to promote bone growth, close the hole and further stabilize the anchor. An elastomeric collar may also be inserted over the shank and extend beyond the end of the shank to flexibly receive a rod seat for receiving an orthopedic rod affixed to said elastomeric collar.

Graft fixation system and method

A graft fixation device, system and method are disclosed for reconstruction or replacement of a ligament or tendon preferably wherein a soft tissue graft or a bone-tendon-bone graft is received and implanted in a bone tunnel. The graft fixation system includes a fixation device comprising a threaded body which is rotatably connected to a graft interface member. One embodiment of the implant / graft interface member includes an enclosed loop for holding a soft tissue graft. Another embodiment of the interface member includes a bone cage comprising a cage bottom and removable cage top to hold a bone block at one end of a bone-tendon-bone (BTB) graft. An additional embodiment of the interface member includes a one-piece bone cage which may be crimped or stapled to a bone block. The fixation device holds a graft in centered axial alignment in a bone tunnel. The body portion of the fixation device may be turned without imparting substantial twist to a graft attached to the device, due to the rotatable coupling between the threaded body and the interface member. The fixation device may be installed using a driver tool that has a shaft and an outer sleeve, wherein the driver may be used to twist the fixation device and independently exert a pushing or pulling force thereto. The graft fixation method may be used to install a fixation device by pulling or pushing it into a prepared bone tunnel while minimizing the possibility of abrasion or other damage to a graft attached to the fixation device.
