摘要:
Methods and devices are provided for the repair of bone defects. The bone defect repair may be accomplished by minimally invasive means. The bone defect repair may utilize a bone growth promoting substance. The bone growth promoting substance may comprise a carrier material and at least one osteoinductive formulation.

A ball and socket joint prosthesis for use in arthroplasty is provided. The prosthesis includes a body for implantation at least partially within the medullary canal of a long bone. The long bone defines trabeculae in the proximal cancellous bone and lamellae in the cortical bone. The body includes a proximal portion thereof and a distal portion. The proximal portion has a medial periphery and includes surface features on a substantial portion of its proximal portion. The surface features are positioned to optimally transfer load from the prosthesis to the long bone.

The present invention is directed to a textured bone allograft for implantation in a patient, having one or more textured bone surfaces, and methods of making and using the textured bone graft. The textured surface preferably includes a plurality of closely spaced discrete, continuous, or a combination thereof, protrusions. The textured bone allograft is useful for repairing bone defects caused by congenital anomaly, disease, or trauma, in a patient, for example, for restoring vertical support of the anterior column. Implantation of the textured bone allograft results in improved graft stability and osteoinductivity, without a decrease in mechanical strength. The textured bone allograft does not shift, extrude or rotate, after implantation.
摘要:
A variable position bone drilling guide apparatus for aiding a surgeon in preparing a bone site. The guide apparatus includes a template that is formed to include apertures therethrough and drill towers extending form the template in general alignment with the apertures. The first drill tower includes at least one drill passage therethrough and the second drill tower includes two drill passages therethrough. The duel passages in the second tower provide a surgeon with greater than one drill alignment option for a bone plate.
摘要:
The joint implant manufacturer obtains and compiles surgeon-specific surgical and supply preference information in relation to a supplied joint implant prior to surgery. The manufacturer designates and trains at least one surgical team member using the surgeon-specific preference information and then supplies the service of the surgical team member(s) together with the supplied joint implant and supplies. The surgical team member(s) perform surgical procedures on the patient to assist the surgeon in removing a defective joint and replacing it with the supplied implant in accordance with the surgeon's surgical preferences.
摘要:
Allogenic or xenogenic materials are used to provide intervertebral disc nucleus implants and/or annular plugs. The allogenic or xenogenic materials comprise natural disc annulus material, which may have a portion of the anterior longitudinal ligament attached. The tissue may be used “as is” without an additional core or covering, or it may be used in combination with other materials. The material may be rolled, folded, layered and/or sutured, stapled, or glued to provide a solid plug of natural biological material. The implant may be provided as a dehydrated, substantially rod-shaped segment having a diameter less than the diameter of the hydrated material, and may have one or more ends of the dehydrated rod terminate with a further reduced diameter portion, preferably a point.

A ball and socket joint prosthesis (10) for use in arthroplasty is provided. The prosthesis includes a body (32) for implantation at least partially within the medullary canal (24) of a long bone (12). The long bone defines trabeculae (60) in the proximal cancellous bone (22) and lamellae (71) in the cortical bone (65). The body includes a proximal portion (52) thereof and a distal portion (54). The proximal portion has a medial periphery (69) and includes surface features (64) on a substantial portion of its proximal portion. The surface features are positioned to optimally transfer load from the prosthesis to the long bone.

A prosthetic acetabular cup assembly includes a single piece bearing component having an inner bearing surface for receiving a ball attached to a femoral prosthesis and an outer surface. The assembly also includes a shell component for attachment to an acetabulum to replace a natural hip socket includes an inner surface defining a cavity for receiving the bearing component therein. The inner surface of the shell component is formed to include an arcuate groove therein. A formed wire is situated in the arcuate groove of the shell component. The wire is configured so that a portion of the wire extends radially inwardly from the arcuate groove of the shell component to engage an arcuate groove formed in the bearing component to retain the bearing component inside the shell component. Anti-rotation lugs are formed on the inner surface of the shell component to cut into the outer surface of the bearing component as the bearing component is inserted into the shell component to prevent rotation of the bearing component relative to the shell component.
摘要:
An orthopedic device includes a drill guide configured to be mounted on a patient-specific alignment guide for intraoperatively confirming alignment of the patient-specific alignment guide relative to a bone. The patient-specific alignment guide includes first and second referencing holes. The drill guide includes a main body with a first coupling member and a second coupling member. The first and second coupling members are configured to be received within the first and second referencing holes, respectively. The first and second coupling members each include corresponding first and second drill openings configured to align with the first and second referencing holes, respectively. The drill openings each guide a drilling tool toward the bone to drill corresponding holes in the bone. The main body also includes an alignment confirmation feature configured for confirming alignment of the patient-specific alignment guide relative to the bone before drilling holes in the bone.
