摘要: A tensioner system for use in tensioning graft strands in a knee reconstruction procedure can include a handle assembly, a tensioner assembly coupled relative to the handle assembly, and a drive shaft slidably received through and supported by the handle assembly. The tensioner assembly can include an arm support member rotatably coupled to the handle assembly and first and second arm members each rotatably coupled to lateral sides of the arm support member. Each arm member can include at least one graft attachment area adapted to be coupled to a graft strand. The arm support member can be configured to rotate about an axis perpendicular to a longitudinal axis of the tensioner system and perpendicular to an axis of rotation of each of the arm members. The drive shaft can include proximal and distal ends that extend beyond respective proximal and distal ends of the handle assembly.

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.

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: 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: 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: 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.
