Systems and methods for attaching soft tissue to an implant
An implant has a soft tissue attachment structure, and a surface defining a trough. An ingrowth plate spans a portion of the trough and defines a suture tunnel between the ingrowth plate and the trough for receiving suture. The ingrowth plate bows convexly away from the surface and is perforated to facilitate long-term ingrowth and biologic fixation of soft tissue to the implant.
CONNECTIVE TISSUE TO BONE INTERFACE SCAFFOLDS
Connective tissue-to-bone interface scaffolds (e.g., ligament-to-bone interface scaffolds, tendon-to-bone interface scaffolds, etc.). These scaffolds may be a single integrated implant or may be a modular (e.g., two-part) implant system.
Connective tissue to bone interface scaffolds
Connective tissue-to-bone interface scaffolds (e.g., ligament-to-bone interface scaffolds, tendon-to-bone interface scaffolds, etc.). These scaffolds may be a single integrated implant or may be a modular (e.g., two-part) implant system.
GLENOID BONE GRAFT RETENTION PLATE
A bone graft retention plate for implantation into a human glenoid and provides stabilization and compression of bony graft material is disclosed. The plate includes channels or apertures for suture or polymer retention cerclage that exhibit curved, smooth surfaces within the plate to allow the retention cerclage to pass through the plate while limiting friction and thus protecting the integrity of the retention means. The plate also includes surface features, such as spikes and posts, to provide further stabilization and implantation positioning. The plate features result in the distribution of forces across the surface area of a bone graft and achieve satisfactory compression of the bone graft against the glenoid without using fixation screws. An associated implantation technique uses a cerclage of suture or tape to bind the implant within the glenoid and may be employed in both open and arthroscopic surgical procedures.
Implant system for repair or replacement of tension carrying connective tissue
A link (1) for connecting two loops of a flexible tension-carrying construct (2, 2a). It solves the problem of providing effective means to connect two anchor points (7, 7a), typically on bones articulating at a joint by the flexible tension-carrying construct.
Stemless Shoulder Implant With Button Lock
A system for shoulder repair includes a prosthetic stemless shoulder implant including a base member extending along a longitudinal axis from a first side to a second side. The second side adapted to engage bone of a patient. The base member defines a hole that extends along the longitudinal axis and through the second side of the base member for receiving a flexible member therethrough. The system includes a fixation construct including a first fixation device and a second fixation device, the first and second fixation devices connected by the flexible member. While the first fixation device is positioned outside of the second side of the base member and the second fixation device is positioned within the base member, the flexible member is adapted to tension the first fixation device with respect to the second fixation device.
IMPLANTABLE CONTAINMENT APPARATUS
An implant containment apparatus for use with an implant device that defines a cavity that contains a bone graft material, and an implant tool selectively attached to the implant device, the implant containment includes a sack that defines a compartment and an opening that provides access to the compartment, where the compartment is adapted to contain the implant device with bone graft in the cavity and where the opening is adapted to allow the implant tool to extend out of the sack when the implant device is in the compartment, and a pre-attached closing member surrounding the opening adapted to selectively vary the size of the opening between a size that tightly fits around the implant tool and a size that closes the opening.
SYSTEM AND METHOD FOR REPAIRING ARTICULAR SURFACES
A joint replacement system for repairing an articular surface of a first bone of a joint includes an anchor portion and an implant portion. The anchor portion includes an anchor to be secured to the bone, and an anchor fixation head including a bone-facing surface (BFS) extending radially outward from the anchor and an implant facing surface (IFS) extending from a periphery of the BFS. The implant portion is formed from a material (e.g., CoCr) more dense than the material of the anchor portion (e.g., Ti) and includes a fixation cavity to receive at least a portion of the anchor fixation head (AFH), the fixation cavity includes an anchor facing surface (AFS) configured to form a frictional connection with the IFS, and a load bearing surface having a contour for articulating against a cooperating articulating surface of a second bone of the joint.
Fixation devices and prostheses for soft tissue connection to the same
An orthopedic assembly includes a tibial prosthesis that includes a body that defines an anterior side and a posterior side. The body further incudes a recess in the anterior side of the joint prosthesis and a plurality of openings that extend through the body from the anterior side to the posterior side thereof. At least a first and second opening of the openings are positioned at respective lateral and medial sides of a longitudinal axis of the tibial prosthesis. A modular insert is positioned within the recess of the body such that at least a portion of the modular insert is positioned between the openings of the body. The modular insert is formed separately from the tibial prosthesis and has a porous outer surface to promote tissue ingrowth.
BONE STRUCTURAL DEVICE
A bone structural device including a plurality of bone structural segments, wherein adjacent bone structural segments are pivotally connected to one another about a pivot axis, and the bone structural segments are expandable in height, which is in a direction generally parallel to the pivot axis.
