A method of inserting an intervertebral disc implant into a disc space includes accessing a spinal segment having a first vertebral body, a second vertebral body and a disc space between the first and second vertebral bodies. The method includes securing a first pin to the first vertebral body and a second pin to the second vertebral body, using the first and second pins for distracting the disc space, and providing an inserter holding the intervertebral disc implant. The method also desirably includes engaging the inserter with the first and second pins, and advancing the inserter toward the disc space for inserting the intervertebral disc implant into the disc space, whereby the first and second pins align and guide the inserter toward the disc space.

A minimally invasive method of correcting a bunion includes performing an osteotomy to divide the metatarsal into first and second portions, creating a pocket in the first portion implanting a nail in the pocket, securing a suture to the joint capsule, tensioning the suture to align the great toe with the metatarsal, attaching the suture to the nail, and fastening the nail to the second portion. The nail includes an anchor portion for anchoring in the first portion, a head for attachment to a second portion, a passage for attachment of the suture, a first aperture for a fastener to attach the head with the first portion, and a second aperture for a fastener to attach the head with the second portion.

A bone resection guide for removal of a portion of a bone of a patient. The bone resection guide includes a resecting section and a drilling section. The resecting section has a bone-facing surface, an extension engaging surface, opposed to the bone-facing surface, and at least one resecting slot extending therethrough between the bone-facing surface and the extension engaging surface. The drilling section has a connecting surface, a tool engaging surface, opposed to the connecting surface, and a plurality of guiding bores extending therethrough from the tool engaging surface to the connecting surface. The drilling section is engageable with the resecting section with the connecting surface of the drilling section facing the extension engaging surface of the resecting section and the plurality of guiding bores being aligned with the at least one resecting slot when the drilling and resecting sections are engaged and secured together.

A patient specific guide for hip replacement for patients undergoing hip replacement surgery. The guide works for correction of the acetabulum defects based on a finite element model, which detect the bone quality and guide the surgeons for the optimum screws trajectories. The guide surface reflects the acetabular morphology which provide a correct posting of the cup, especially for the complex case as bone loss, severe fractures and tumors. CT-scan images are used to construct the 3D model of the acetabulum bone, therefore a finite element and virtual surgery planning methods are applied to create the electronic file of the patient specific guide. In final step, the 3D printers are used to produce the patient specific guide.

A guide apparatus for a surgical cutting tool includes a plurality of plates arranged in parallel with a guide plane. The plates form opposing bearing surfaces spaced apart over a clearance distance that defines an opening. A sheath includes a cylindrical portion that extends along a longitudinal axis and forms an interior passage extending through cylindrical portion along the longitudinal axis. The cylindrical portion of the sheath slidably engages the opening through the clearance distance, and the interior passage of the sheath receives a rotary cutting head of the surgical cutting tool in an operating configuration.

A targeting guide is disclosed includes a handle extending substantially along a longitudinal axis. The longitudinal handle defines one or more burr holes extending from a first side of the handle to a second side of the handle. A head is coupled to a distal end of the longitudinal handle. The head defines a plurality of guide holes sized and configured to receive a k-wire therethrough.

A spinal joint distraction system for treating a facet joint including articular surfaces having a contour is disclosed and may include a delivery device including a generally tubular structure adapted to engage a facet joint, an implant adapted to be delivered through the delivery device and into the facet joint, the implant comprising two members arranged in opposed position, and an implant distractor comprising a generally elongate member adapted to advance between the two members of the implant causing separation of the members and distraction of the facet joint, wherein the implant is adapted to conform to the shape of the implant distractor and/or the articular surfaces of the facet upon being delivered to the facet joint. Several embodiments of a system, several embodiments of an implant, and several methods are disclosed including a method for interbody fusion.

A method of inserting an intervertebral disc implant into a disc space includes accessing a spinal segment having a first vertebral body, a second vertebral body and a disc space between the first and second vertebral bodies. The method includes securing a first pin to the first vertebral body and a second pin to the second vertebral body, using the first and second pins for distracting the disc space, and providing an inserter holding the intervertebral disc implant. The method also desirably includes engaging the inserter with the first and second pins, and advancing the inserter toward the disc space for inserting the intervertebral disc implant into the disc space, whereby the first and second pins align and guide the inserter toward the disc space.

A resection guide includes an anchor having bone anchoring features, a cutting block having a cutting guide defined therein, and a linkage flexibly connecting the cutting block to the anchor. The flexibility of the linkage provides the cutting block with six degrees of freedom of motion relative to the anchor.

The present invention relates generally to a prosthetic spinal disc for replacing a damaged disc between two vertebrae of a spine and methods for inserting said discs. The intervertebral prosthetic discs are provided with connections for facilitating implantation and removal and features which enhance primary and secondary stability over time.
