Devices, implements and methods for the treatment of a multi-axis joint |
摘要 |
A system, devices and methods for performing an osteotomy on a bone of a multi-axis joint are provided. A cutting guide system is provided for performing one or more cuts to the bone, using the articular surfaces of the articulating bones as a reference. If desired, a prosthesis can be used to emulate the osteotomy and substitute for a damaged articular surface of a bone of a multiaxis joint. |

1. A prosthesis for a first bone of a joint, comprising:
a head portion adapted to articulate with a second bone of the joint, said head portion including an articular surface emulating a native post-osteotomy articular surface of the first bone, said articular surface including a saddle shaped articular surface that is circularly concave in a dorsal-palmar plane and circularly convex in a lateral-medial plane; the head portion including a dorsal lip and a palmar lip, the palmar lip protruding beyond the dorsal lip such that a line tangent to a most proximal point on the dorsal lip that is also tangent to a most proximal point on the palmar lip will be inclined at an angle of more than 270 degrees relative to a longitudinal axis through the prosthesis; a stem portion adapted for insertion into the medullary cavity of the first bone; and a keel portion extending from a palmar side of said stem. |
