The present invention discloses a cable passer device and method for placement of a cerclage cable for internal fixation of bone. The device comprises a cannulated body including a proximal end, a straight portion, an arcuate portion, and a distal end. The straight portion extends from the proximal end, and the arcuate portion extends from the straight portion and ends at the distal end of the cannulated body. A continuous groove extends from the proximal end to the distal end through the straight portion and the arcuate portion of the cannulated body. The groove extends radially along an internal diameter of the cannulated body. An opening of the groove facilitates to receive the cerclage cable therein. The width of the opening remains the same throughout an entire length of the continuous groove. The groove includes varying angle to facilitate unimpeded movement of cerclage cable therethrough.

A fixation mechanism that more effectively limits or prevents relative movement between two adjacent objects includes an elongated tie having a free end and a joined end and a clasp coupled to the joined end of the tie. The clasp includes a housing having an insertion channel in which the free end of the tie is inserted and an exit channel through which the tie exits such that the tie and clasp form a loop that connects the two adjacent objects. The clasp further includes a locking mechanism positioned in the housing between the insertion channel and the exit channel. The locking mechanism includes a locking tine that permits the free end of the tine to pass forwardly through the insertion channel and out the exit channel but grips the tie to prevent it from moving rearwardly out of the housing.

A bone fixation clamp includes first and second clamp members, a stud, and a locking nut. The first member extends along a curve corresponding to an outer surface of a first portion of bone and includes an opening extending therethrough along an axis extending adjacent to the bone. The second member extends along a curve corresponding to an outer surface of a second portion of bone. The stud is receivable within the opening of the first member. The nut includes a threaded channel threadedly engaging a portion of the stud so that, when the first and second members are in the operative configuration, the nut is threadable over the stud to fix the first and second members over bone. The nut includes an anti-loosening feature which, when the nut is threaded over the stud, results in an interference with threading along the stud.

An elbow prosthesis according to the present teachings can include a stem structure and an articulating component. The stem structure can be operable to be positioned in a bone of a joint. The stem structure can include a stem portion that is operable to be positioned in the bone and a C-shaped body portion having a first retaining mechanism formed thereon. The articulating component can have a second retaining mechanism formed thereon. One of the first and second retaining mechanisms can comprise an extension portion and a first anti-rotation portion. The other retaining mechanism can comprise a receiving portion and a second anti-rotation portion. The articulating component can be advanced from an insertion position to an assembled position, such that the first and second mechanisms cooperatively interlock to inhibit translation and rotation of the articulating component relative to the C-shaped body portion of the stem structure.

A crimp cap apparatus includes: a crimp sleeve having a peripheral wall defining an exterior surface and an interior passage sized to receive a tensile member having a predetermined outer diameter, the crimp sleeve being configured such that it can be crimped around the tensile member by an application of mechanical force which reduces its dimensions from a first size to a second, smaller size; and a cap having a bottom surface, a convex top surface, a central bore extending from the bottom surface to the top surface for receiving the crimp sleeve, wherein the cap includes a clamping structure disposed in the central bore and configured to permit elastic deflection in response to being pressed over the crimp sleeve the crimp sleeve and apply a clamping force there-to to secure the cap in place.

A sternum fixation device includes a plate having a first end and a second end, a right lateral edge and a left lateral edge, an inner side configured for placement against the sternum, and an outer side. A first lobe includes a band socket defined as a blind recess in the outer side of the plate. The band socket includes a right lateral stop and a left lateral stop opposite the right lateral stop. A right lateral channel is defined in the first lobe from the right lateral edge to the band socket, the right lateral channel defined above a right side floor in the socket. A left lateral channel opposite the right lateral channel is defined in the first lobe from the left lateral edge to the band socket, the left lateral channel defined above a left floor in the socket.

A method for attaching a flat and flexible band on at least one bone part is disclosed. The band includes two end portions. A rigid base body crossed by an opening, and a retaining part that can be inserted in the opening is employed. The retaining part is at least partially in the shape of a squeezable wedge comprising a central bore for passage of the end portions facing the flexible band, the bore having a transverse cross-section that can be deformed between a first cross-section for free passage of the end portions when the part has not been inserted in the opening and a second cross-section for locking the end portions by compression when the part is entirely or substantially entirely inserted in the opening.
