The present invention also relates to methods of manufacturing bioactive composites. The bioactive composite finds utility in a variety of load-bearing clinical applications including spine, orthopaedic and dental procedures.
Abstract:
The disclosure includes a method for providing prosthetic implants for a total knee replacement procedure. This method includes receiving data representative of a knee joint of a patient and determining anatomical parameters from the received data. The method also includes creating a graphical model of the knee joint based on the determined anatomical parameters, and providing a femoral component of a knee joint implant based on at least one of the determined anatomical parameters and the graphical femoral portion. This method also includes providing at least one cutting instrument configured to facilitate removing a portion of the femur of the patient based on at least one of determined anatomical parameters and the graphical model.
Abstract:
A system for treatment of tissue includes a fixation apparatus and a delivery tool releasably carrying the fixation apparatus. The fixation apparatus includes first and second anchors and an adjustable band connecting the anchors. The band includes a cinch line and a tether connected to one of the anchors. The delivery apparatus includes a body, a tubular shaft, a displacement rod within the tubular shaft, and an actuator.
Abstract:
A prosthesis, in particular a shoulder prosthesis, includes a socket part receiving a joint head; an anchoring part anchoring the prosthesis in a bone; and a connecting arrangement securely connecting the socket part to the anchoring part. The socket part is assigned at least one pin and the anchoring part has at least one guide. The guide is designed in such a way that the pin can be held substantially safe from tilting in the guide.
Abstract:
An orthopedic surgical instrument includes a patella trial and drill guide that may be used to both perform a surgical trial of the patellofemoral joint and guide the surgeon in drilling a number of anchor holes in the patella of the patient.
Abstract:
An intervertebral implant is provided. The intervertebral implant comprises a first component comprising an outer tissue engaging surface and an inner surface. A second component is connected to the first component, and is relatively moveable therefrom. The second component comprises an outer tissue engaging surface and an inner surface. The second component includes an actuator. A third component is disposed for engagement and is movable relative to the first and second components. The third component comprises at least a first ramp and a second ramp axially spaced apart from the first ramp. The actuator is engageable with the third component to effect axial translation of the wedge such that the ramps engage the inner surface of at least one of the first component and the second component to move the components between a first, collapsed configuration and a second, expanded configuration. Methods of use are disclosed.
Abstract:
A method and apparatus for stabilizing first and second adjacent bone portions. The method includes the steps of: providing a spacer; providing a stabilizer, with the spacer and stabilizer configured to be movable guidingly, one relative to the other, between a pre-assembly relationship and an operative relationship; and placing the spacer and stabilizer into an operative relationship with the first and second adjacent bone portions. As an incident of the spacer and stabilizer being changed from their pre-assembly relationship into the operative relationship with each other and the first and second bone portions, the spacer, stabilizer and first bone portion cooperate to cause the first bone portion and spacer to be urged towards each other. The method may be carried out by moving the stabilizer and spacer, and all auxiliary parts and handling and assembling instruments, substantially in a single plane along one line or parallel lines.
Abstract:
A bone graft system for providing bone graft material to a site of interest includes a multiple unit bone graft material loading device and a conduit. The multiple unit bone graft material loading device may be configured to accept a plurality of pre-formed bone graft material units and includes a plurality chambers configured to accept a pre-formed bone graft unit. The conduit may include a first opening and second opening. The first opening may be operably connected with the multiple unit bone graft material loading device to accept bone graft material from the multiple unit bone graft material loading device. The second opening may be configured to deliver bone graft material to a site of interest.
Abstract:
The present invention relates to devices and methods for treating one or more damaged, diseased, or traumatized portions of the spine, including intervertebral discs, to reduce or eliminate associated back pain. In one or more embodiments, the present invention relates to an expandable interbody spacer. The expandable interbody spacer may comprise a first jointed arm comprising a plurality of links pivotally coupled end to end. The expandable interbody spacer further may comprise a second jointed arm comprising a plurality of links pivotally coupled end to end. The first jointed arm and the second jointed arm may be interconnected at a proximal end of the expandable interbody spacer. The first jointed arm and the second jointed arm may be interconnected at a distal end of the expandable interbody spacer.
Abstract:
A talonavicular joint prosthesis (1) adapted to replace the natural talonavicular joint that exists between a patient's talus and navicular bones, after appropriate surgical preparation of the joint-related portions of these bones so as to create a new joint space to accommodate this prosthesis, includes talar (2) and navicular (4) components. Each of these have inner (8, 28) and outer (6, 26) surfaces whose average separate distance is defined as the component's average thickness. These components inner (8, 28) surfaces are configured to: (a) generally follow the anatomic contour of the original joint surface to which each component is to be attached, and (b) minimize each component's average thickness, consistent with providing sufficient strength and rigidity for the components, so as to require minimum bone resection in the creation of the new prosthesis-accommodating, joint space.
