An apparatus for anchoring one or more tensile members to bone includes: an anchor, including: a housing having a hollow interior, and including a body portion and an extension portion interconnected by a breakaway structure configured to retain structural integrity under a first predetermined tensile load and to separate under a second predetermined tensile load which is greater than the first predetermined tensile load; a collet disposed in the hollow interior, the collet having a peripheral wall defining a central bore for accepting one or more tensile members therethrough; a sleeve having a peripheral wall and being disposed in the hollow interior of the housing, so as to be movable parallel to the central axis; and wherein the sleeve and the collet are arranged such that axial movement of the sleeve will cause the collet to swage radially inwards around and against the one or more tensile members.

This invention relates to a coupling for an orthopaedic device. Also disclosed in an orthopaedic device comprising a coupling of the invention and method for the use of the orthopaedic device. The orthopaedic device finds utility as a bolt apparatus for fixation of bones such as fractures of the femur, although it may be used in any suitable bone.

A method for anchoring one or more tensile members to bone includes: providing an anchor, including: a housing including a body portion and an extension portion interconnected by a breakaway structure which is configured to retain structural integrity under a first predetermined tensile load and to separate under a second predetermined tensile load which is greater than the first predetermined tensile load; a collet disposed in the hollow interior; and a sleeve movable parallel to the central axis between first and second positions; passing one or more tensile members through a central bore of the collet; seating the housing into a bore formed in the bone; and driving the sleeve from the first position towards the second position under the first predetermined tensile load, so as to swage the collet around the one or more tensile members.

An intramedullary bone fixation device is provided with an elongate body having a longitudinal axis and an actuator to deploy at least one gripper to engage an inner surface of the intramedullary space to anchor the fixation device to the bone. Methods of repairing a fracture of a bone are also disclosed. One such method comprises inserting a fixation device into an intramedullary space of the bone to place at least a portion of the fixation device on one side of the fracture, providing rigidity across the fracture, and operating an actuator to deploy at least one gripper to engage an inner surface of the intramedullary space to anchor the fixation device to the bone. Various configurations allow a segmented device body to lock in the intramedullary space before and/or after fixation of the bone.

Provided herein are bone anchor devices including embodiments using adaptive materials, including shape memory materials such as shape memory alloys. Embodiments using shape memory alloys may use super-elastic properties of shape memory alloys to provide forces and deflections that actuate bone anchoring element(s) within bones. Embodiments of bone anchoring elements may be created that actuate with respect to one or more pivot point(s), with the bone anchoring elements on an opposite side of the pivot point from the actuating member composed of, for example, shape memory material. The pivot point(s) of a bone anchor device may be positioned in a central portion of the bone anchor device. The central portion of the bone anchor device may span between two pieces of bone or two separate bones (e.g., two bones of a joint) into which bone anchoring elements may be embedded and fixed.

The present application relates to repair systems, and more particularly to fifth metatarsal repair systems and methods of use. The repair systems described herein can include a fixation device with a threaded section. The repair systems described herein can include one or more grippers designed to be deflected outward to grip the sidewalls of an intramedullary canal of the fifth metatarsal. The repair systems described herein can include an end cap. The end cap can include a fastener including thread designed to engage the threaded section of the fixation device. The end cap can include a cap designed to move relative to the fastener.

A stent is disclosed that has an elongated body composed of a bioabsorbable polymer having a proximal end, a distal end, two open spiral channels formed on the exterior surface of the body to provide fluid communication between the proximal end and the distal end. The stent also has a central lumen open at the proximal and distal ends of the stent for the passage of a guide wire. A method for using the stent and a kit containing the stent are also disclosed.

A bone screw for treating a bone fracture having a detent assembly on a body portion thereof. The detent assembly operative to secure the body from movement relative to a bone nail. The detent assembly includes a detent member, for example, an annular member, movable between a first and second position. Positioning the annular member in the second position operates to secure the body of the bone screw from movement relative to the bone nail.

Provided are tibia stem components of ankle replacement prosthesis that are designed to engage dense tibia bone to reduce implant migration over long term.
