CUSTOMIZED UNICOMPARTMENTAL TIBIAL CUTTING GUIDE

摘要

A customized unicompartmental tibial cutting guide for orthopedic surgery is provided. The tibial cutting guide includes a first mating surface having a customized patient-specific negative contour to match a corresponding contour of an anterior region of a tibia of a patient and a second mating surface extending transverse to the first mating surface to a midpoint of a tibial plateau of a medial or lateral condyle of the tibia. The second mating surface includes a customized patient-specific negative contour to match a corresponding contour of a mid-region of the tibial plateau of the medial or lateral condyle. The second mating surface is limited to a region between an intercondyloid eminence and a lateral or medial edge of the tibial plateau. The tibial cutting guide also includes a first cutting guide surface and a second cutting guide surface positioned transverse to the first cutting guide surface.

1. A customized unicompartmental tibial cutting guide for orthopedic surgery comprising:
a first mating surface including a customized patient-specific negative contour to match a corresponding contour of an anterior region of a tibia of a patient; a second mating surface extending substantially transverse to the first mating surface to about a midpoint of a tibial plateau of a medial condyle or a lateral condyle of the tibia, the second mating surface including a customized patient-specific negative contour to match a corresponding contour of a mid-region of one of the tibial plateau of the medial condyle or the tibial plateau of the lateral condyle, wherein the second mating surface is limited to a region between an intercondyloid eminence and a lateral or a medial edge of the tibial plateau; a first cutting guide surface positioned distal to the second mating surface; and a second cutting guide surface positioned substantially transverse to the first cutting guide surface and adjacent a medial side of the first mating surface.
