摘要： An implantable bone anchor assembly for fixing an elongated member such as a spinal rod may include a bone anchor, a coupling head configured to receive the bone anchor and the elongated member, and a locking mechanism. The locking mechanism may provide compressive force to simultaneously fix the position of the elongated member and lock out polyaxial rotation of the bone anchor relative to the coupling head. The locking mechanism may include an engagement member with an oblique surface configured to slide along an oblique surface of the coupling head into engagement with the elongated member. The bone anchor may comprise a head portion and a threaded portion which may be coupled with the coupling head and joined together during manufacture. The assembly may further include a pin and/or a collar to retain the bone anchor. The bone anchor may be side-loaded into the coupling head.

摘要： A surgical instrument and method are provided for removal of a spinal implant from the intervertebral disc space. The instrument includes a carriage body for interfacing with the implant, a housing for interfacing with the vertebrae, and a handle portion having a first portion rotatably coupled with a proximal end of the housing and a second portion rotatably engageable with a proximal attachment portion of the carriage body. A central passage of the housing extends between the proximal end and a distal engagement surface of the housing. The central passage is dimensioned to mate with the carriage body. Rotation of the handle portion about an axis causes translational movement of the carriage body along the axis. A modular inserter/distractor apparatus and method and an anchor remover and method are also provided.

摘要： A total hip femoral prosthesis provides a shortened neck and more proximal coating level. Additionally, a means for strengthening the neck may be incorporated to increase stress transfer to the native bone. A method for reducing potential impingement that results from a high neck resection level includes instrumentation for cutting chamfered surfaces into the bone surrounding the proximal end of the implant. Instrumentation and methods of creating chamfered cuts are disclosed.

摘要： Methods and instrumentation for implantation of an intervertebral disc prosthesis are provided. A guide tool with sagittal and coronal reference features guides placement of guide pins relative to a sagittal plane and a coronal plane of the vertebrae. A retainer lockable to the guide pins has a ratcheting mechanism providing distraction or compression. A rasp, planer or other tools may be aligned to the retainer and inserted into the intervertebral space to prepare the vertebral endplates. An interoperatively adjustable trial is alignable to the retainer and measures an angularity of the intervertebral space. A prosthesis with keying features may be mounted to a prosthesis inserter with complementary features, held by pivotable arms and compressed between prongs. The inserter may be aligned to the retainer and advanced to implant the prosthesis in the intervertebral space. A prosthesis remover may grip one prosthetic end plate and extract the entire prosthesis.

摘要： A system for accessing a spine from a curved postero-lateral approach may include a curved cannula positioned along a curved path from an opening in the skin to a location proximate the spine. The location may be at the L4-L5 vertebral level, and the curved path may lie in a plane oblique to the transverse, coronal and sagittal planes of the spine, and avoid the iliac crest. A targeting post may be inserted adjacent the spine to determine the location, and a guide member may be inserted to establish the curved path. A micrometer assembly may adjust a cephalad-caudal displacement between the post and the guide member. One or more intermediate cannulas may be inserted over the guide member to dilate tissues prior to insertion of the main cannula. An interbody device may be implanted into an intervertebral space through the cannula.

摘要： A system for accessing a spine from a curved postero-lateral approach may include a curved cannula positioned along a curved path from an opening in the skin to a location proximate the spine. A guide member may be first inserted to establish the path between the tissues and fascia, and one or more intermediate cannulas may be temporarily inserted over the guide member to dilate the tissues prior to insertion of the main cannula. An interbody device may be implanted in an intervertebral space through the cannula. The system may include a guide bar removably coupled to a targeting post. The targeting post may be inserted adjacent the spine to provide a target, and the guide bar may be removably attached to the guide member, to guide it along the path to the target location. An external support arm may be secured to any other component of the system.

摘要： The present invention provides artificial disc prostheses, methods and instrumentation for implantation and revision thereof. Each prosthesis may comprise superior and inferior end plates and a nucleus positioned between articular surfaces of the end plates. The end plates may have planar bone engagement surfaces with a plurality of self-cutting teeth. The articular surfaces of the end plates may be planar or include a flattened portion. The nucleus includes superior and inferior articular surfaces which may comprise flattened portions such that when the articular surfaces of the nucleus and the end plates are placed in cooperation in a preferred orientation, the flattened and/or planar portions are aligned. Each prosthesis may provide flexion/extension, anterior/posterior translation, lateral bending, and/or axial rotation degrees of freedom. One embodiment comprises a prosthesis with a first joint providing flexion/extension and anterior/posterior translation, and a second joint providing lateral bending and axial rotation.

摘要： Facet fixation implants include a cap member with a circular base portion and an eccentric raised portion. The raised portion includes first and second lobes and is smoothly contoured to provide an unobtrusive profile when implanted. Beveled teeth project from the implant to provide fixation and compression across the facet joint. The cap member includes an offset aperture which receives a fastener. Tools, guiding instruments and methods for implantation of the implants are disclosed.

摘要： A soft tissue repair device can include a housing having a handle, a deployment system having an actuation member, and an insertion system having an inserter and a slider. The slider can be coupled to the actuation member and movable relative to the inserter between deployed and retracted positions. First and second anchors can be carried on an external surface of the slider such that the anchors are spaced apart and portions of the anchors are coaxial with the slider and each other. A flexible strand can couple the anchors. The insertion system can cooperate with the deployment system to move the slider to the deployed position to deploy the first anchor upon activating the actuation member a first time, and to move the slider to the deployed position from the retracted position to deploy the second anchor upon actuating the actuation member a second time after the first time.
