A composite for osteochondral defect repair includes a porous scaffold and a periosteal graft secured to a surface of the scaffold. The composite provides cartilage growth from autologous periosteum chondrogenesis. Biological resurfacing of large osteochondral defects, or a complete joint is feasible using the porous scaffold/autologous periosteal composite. The use of this composite eliminates the necessity of using normal cartilage surface as a donor site and its respective associated morbidity. In one form, the strong bone integration capacity of a porous metal (e.g., tantalum) scaffold and the high grade of integration observed from periosteal chondrogenesis into the normal cartilage eliminates the lack of chondral-chondral integration observed in the autologous osteochondral graft technique.

A method of bone fixation. A guide device may be disposed such that a first portion of the guide device is disposed longitudinally in a medullary canal of a bone and such that a second portion of the guide device is disposed outside the bone and defines a transverse path across the bone and intersecting the medullary canal. A transverse hole may be formed in the bone along the transverse path, and a fastener may be disposed in the transverse hole. A rod may be placed longitudinally in the medullary canal such that a threaded portion of the rod enters an aperture of the fastener and engages the fastener at the aperture to lock the rod to the fastener. The first portion of the guide device may be removed from the medullary canal after the step of forming a transverse hole and before the step of placing a rod.

An ancillary tool for fitting a humeral component of a total or partial elbow prosthesis, comprising a guiding tool () for boring a humeral trochlea (T) along a geometric axis (X-X') of bend of a joint to be equipped with said prosthesis. The guiding tool () includes a stirrup element () and means () for securing said stirrup element on the humeral trochlea (T) so that said guiding tool defines a guiding zone that is aligned in the geometric axis of bend for the introduction (F) of a drill (), a punch or the like, in the humeral trochlea (T) along said geometric axis of bend. This ancillary tool also comprises at least one stepped template () for determining an anterior offset of said geometric axis of bend (X-X&#x2032;) with respect to a humeral diaphyseal axis (Y-Y&#x2032;).

An ancillary tool () comprising a trial humeral trochlea () that is representative of an anatomical humeral trochlea when the trial humeral trochlea is in place with respect to corresponding cubital (S) and/or radial (S) articular surfaces and a cut-out guide () for cutting an ulna (C) and/or a radius (R), wherein the cut-out guide () is adapted to be positioned with respect to the trial humeral trochlea (). The cut-out guide () is also adapted to be positioned with respect to an ulna (C) and/or to a radius (R) equipped with the trial humeral trochlea ().

Systems for replacement of the ends of bones with prostheses, and methods of using the systems for bone replacement.

Systems for bone replacement

A multi-functional brace for a joint includes a releasable locking mechanism that allows the brace to be set for static stretch of the joint in either flexion or extension, and a range of motion assembly that allows for free movement of the joint through its natural axis over a controlled range of motion when the locking mechanism is released.

A prosthesis for the radius bone in the arm of a patient includes a head shaped for engagement with the capitellum of a humerus bone and the radial notch of the ulna. It also has a curved stem that extends from the head and is tapered with a distally decreasing cross section for insertion into the medullary canal of the radius. A system for implanting the prosthesis requires a resection guide for placing the forearm of the patient in a precise anatomical orientation for resection of the radius bone. The resection guide includes a notched alignment rod attached to an adjustable flange and a reference flange for aligning the forearm for a cut of the radius bone perpendicular with the axis of rotation of the radius bone about the ulna, and for measuring the size of the resection and prosthesis.
