Abstract: This glenoidal component for a shoulder prosthesis comprises a base which may be immobilized on the glenoid cavity of a shoulder, and an element provided to be mounted on this base and forming a convex surface of articulation centered on an axis of symmetry. This axis of symmetry is non perpendicular to a rear face of the base intended to abut against the glenoid cavity, this making it possible to compensate a defect in parallelism between the resectioned surface of the glenoid cavity and the axis of the patient's spinal column. A surgeon can select the component in which the axes of symmetry of the components are oriented differently with respect to their rear faces.

Abstract: A prosthesis that mechanically couples with both cancellous bone and cortical bone of a glenoid includes a head portion comprising a rear surface and an articular surface, an anchor member, and a plurality of deformable fins extending radially outward from the anchor member. The anchor member includes a distal end and a proximal end connected to the rear surface of the head portion. The plurality of deformable fins extend radially outward from the anchor member and includes at least a first proximal fin adjacent to the rear surface of the head portion positioned to engage with the cortical bone. The anchor member may also include at least one distal fin located proximate the distal end of the anchor member positioned to engage with the cancellous bone.

Abstract: Systems, apparatuses and methods for securing tissue to bone using a bone anchoring system are described. Methods and apparatuses may allow transformation between locked and unlocked states, thereby allowing adjustment of the tension in the suture. The apparatus and/or methods may allow unidirectional movement of a suture, while preventing slippage or movement of the suture and tissue in the opposite direction. Ends of a suture may be individually tensioned to adjust positioning of a tissue with respect to a bone.

Abstract: A glenoid component is provided to reduce glenoid loosening when implanted in orthopedic joint replacement/reconstruction, such for a shoulder. The glenoid component can include pegs or a keel and articulating surface geometry that uses complex, non-spherical geometry to recreate a level of constraint that is adequate, but not excessive, to thereby mitigate loosening of the glenoid component after implantation. In addition, some embodiments provide that peak stresses both within cement and at an interface of the cement and a supportive component can be reduced. Further, geometry of the pegs can allow stresses to be evenly applied to a cement mantle formed in the supportive component. Finally, the pegs can be configured to desired lengths in order to avoid placement in areas of the supportive component, for example, that have insufficient bone stock.

Abstract: Some embodiments of the present invention include a suture anchor with both knotless and knotted suture attachment capabilities, as well as methods for loading the suture in knotless and knotted configurations. Some embodiments of the present invention include a suture anchor with an inner implant body with a spreader that slides in relation to an outer expandable collar, such that pushing the expandable collar distally with an inserter causes the spreader to expand the collar against the surrounding bone to secure the suture anchor in place. Such embodiments may also include a detachment or breakaway feature between the inserter and the suture anchor to permit separation after anchor deployment. Some embodiments of the present invention include methods for deploying such suture anchors and expanding the expandable collars and/or detaching the inserter tools. Embodiments of the present invention may be used in various orthopedic applications such as, for example, shoulder repair.

Abstract: An orthopedic device and method of use are provided that incorporate complex, non-spherical articulating surfaces to allow a greater available range of motion compared with existing artificial shoulder joint and artificial hip joints. According to some embodiments, complex, non-spherical articulating surfaces can be incorporated on a humeral head and/or glenoid of a shoulder prosthesis. In other embodiments, complex, non-spherical articulating surfaces can be incorporated on the acetabulum and/or femoral head of a hip prosthesis. These non-spherical surfaces can be used to adjust constraint, joint thickness, soft tissue tension, moment and arc of motion, and in doing so, influence motion.

Abstract: The device (1) comprises a first snare (10) and a second snare (20), each of these snares comprising a contractable hollow elongated body (11, 21) which defines a longitudinal central axis (X10, X20) and which reduces its cross section when two opposed first (12, 22) and second (13, 23) ends thereof are axially moved away from each other. The first end (12) of the first snare (10) and the first end (22) of the second snare (20) are each open and adapted to be fitted and tightened around, respectively, two stumps (T1, T2) of a soft tissue (T) to be repaired. The second end (13) of the first snare (10) and the second end (23) of the second snare (20) are adapted to the axially pulled so that the second end of each of the two snares is passed alongside or through the body (11, 21) of the other snare.

Abstract: Methods of implanting a prosthesis to repair a joint include displacing a first bone from the joint formed by an intersection between the first bone and a second bone. An end portion of the first bone is resected to define a resected end. A concavity is formed into the resected end using a shaping tool. The bone is compacted to form a support layer lining the concavity. The prosthesis is implanted in the concavity against the support layer without attaching the prosthesis to the support layer. The joint is reformed with the prosthesis such that the prosthesis remains unattached to the support layer and the first and second bones articulate about the prosthesis.
