Abstract:

Systems, methods and device for tibial resection comprise a first cutting guide and a second cutting guide. The first cutting guide () is configured to overlay a portion of the tibia and to direct a cutting instrument in a plane. The first cutting guide has a length extending from a generally medial portion of the tibia to a generally lateral portion of the tibia. The first cutting guide has a depth extending in a posterior direction generally perpendicular to the length and a groove extending along the length and depth of the first cutting guide such that the groove extends along a generally transverse plane. The second cutting guide () is oriented at an angle to the first cutting guide and configured to extend generally in a posterior direction from the first cutting guide (). The second cutting guide limits the cutting instrument in the transverse plane from cutting bone.

International Classification:

A61B 17/58

US Classification:

606 96

Abstract:

A drill guide for aligning a guide pin. In an embodiment, the drill guide comprises a base having a concave inner surface, an outer surface, and a central axis perpendicular to the inner surface. In addition, the drill guide comprises a drilling template extending axially from the outer surface of the base along the central axis. The drilling template includes a plurality of through-bores. Further, the drill guide comprises a first curved member extending along a central longitudinal axis from a fixed end integral with the base to a free end distal the base, and a second curved member extending along a central longitudinal axis from a fixed end integral with the base to a free end distal the base. The first curved member and the second curved member are angularly spaced about 180 apart relative to the central axis and include an elongate locking slot.
