Abstract: An implement, particularly useful as a medical implement for applying a suture to a body tissue, includes a handle and shaft formed with a pair of channels extending from the proximal end of the handle through the distal end of the shaft and through a pair of jaws carried at the distal end of the shaft. The pair of channels converge towards each other to a cross-over point, and then diverging away from each other where existing at the distal end of the shaft. The channels are dimensioned to enable a piercing instrument to be passed first through one of the channels to pierce the body with a first bore, and then through the other of the channels to pierce the body with the second bore, such that the two bores have entry ends precisely spaced a predetermined distance from each other, and exit ends precisely spaced a larger predetermined distance from each other.

Abstract: An instrument for locating the cutting plane on the head of a long bone in a surgical procedure, wherein the head of the bone is replaced with a joint prosthesis component, includes an axial reference shaft which can be arranged parallel to the axis of the bone and a cutting guide which can be moved relative to the axial reference shaft. The cutting guide has a reference block for location against the bone relative to the edge of the bone at one side and at least one arm which is shaped so that it can extend from the cutting guide over the face of the head. The arm can be located positively with respect to features on the head so that the location of the reference block along the axis of the bone can be set with reference to features on the head of the bone which are contacted by means of the arm.

Abstract: A surgical instrument for use in attaching soft tissue to a bone in a surgical site, includes an elongated shaft carrying, at its distal end, a clamping device having clamping jaws and a piercing device for piercing soft tissue, and further carrying, at its proximal end, manipulatable members for manipulating the clamping device to clamp soft tissue between the clamping jaws, and for manipulating the piercing device for piercing the soft tissue when clamped between the clamping jaws, and for drawing a suture through the pierced soft tissue. The surgical instrument further includes, at its distal end, a socket dimensioned to receive an anchor to be implanted in a bore in the bone, which anchor also has secured thereto a suture to be passed through the pierced soft tissue and to be tied to the bone. The invention is particularly described with respect to a method wherein the tissue to be attached is labrum tissue detached from the glenoid bone in a shoulder joint.

Abstract: The invention relates to a modular humeral prosthesis for an inverse shoulder prosthesis, comprising an anatomical shaft (1) and a separable epiphyseal head (2) which may be angularly orientated by rotation about the longitudinal axis (XX) of the anatomical shaft. The anatomical shaft and the epiphyseal head comprise complementary angular indexing means (11, 28) for relative rotational fixation.

Abstract: A humeral component of a reverse shoulder prosthesis includes a stem part configured for location within the intramedullary cavity of the humerus, the stem part having a stem axis, an epiphyseal part connected to the elongate stem part and having a concave bearing surface defining an epiphyseal axis, and wherein the epiphyseal axis is offset posteriorly relative to the stem axis.

Abstract: A trial implant component for use in a surgical procedure for replacement of a joint prosthesis at a joint between a long bone and another bone includes a metaphyseal part which can be located so that it extends into a cavity at the resected face of the long bone in contact with the internal wall of the cavity in the metaphyseal region. The metaphyseal part has a part of a spigot and socket assembly for engaging a mating component which has the corresponding part of the said assembly. The spigot and socket assembly defines an assembly axis, in which the ratio of the length of the metaphyseal part measured between the superior and inferior faces along the assembly axis to its width at the superior face measured generally along the medial-lateral axis is not more than about 1.0.

Abstract: A method of repairing separations in the capsular labrum structure, in which the head of the humerus bone separates from the glenoid cavity of the glenoid, by: producing a first plurality of anchor points in an anterior face of the rim of the glenoid; producing a second plurality of anchor points in a corresponding anterior face of the neck of the glenoid; and utilizing the first and second plurality of anchor points for attaching the tendons to the glenoid. Also described is an apparatus for use in repairing separations in a capsular labrum structure including a drill guide having a proximal end formed with a handle, and a distal end formed with a surface configured for engaging a posterior face of the neck of the glenoid to properly fix the position of the drill guide with respect to the glenoid.

Abstract: The humeral portion of a shoulder prosthesis includes a diaphyseal component configured for fixation within the humerus, a metaphyseal component, configured for removable implantation within the metaphysis of the humerus, and an engagement mechanism for removably engaging the two components. The metaphyseal component can initially include a convex articulating surface that can be replaced with a concave surface during the shoulder arthroplasty procedure or in a subsequent revision surgery. The metaphyseal component can also include a feature to facilitate removal of the component from the bone once it has been disengaged from the diaphyseal component.
