摘要： A low profile patient specific cutting block for a knee comprises a plurality of bone interfacing portions and a cutting slot. The plurality of bone interfacing portions are configured to overlie portions of an end of a bone. The bone interfacing portions each have a surface generally a negative of the portion of the bone the bone interfacing portion overlies. The bone interfacing portions are angularly offset from each other such that a first of the bone interfacing portions overlies an anterior portion of the bone and a second of the bone interfacing portions overlies a portion of bone generally perpendicular to the anterior portion of bone. The cutting slot is oriented in a fixed position relative to the bone interfacing portions such that the cutting slot directs a cutting tool at a fixed angle and at a fixed depth from the bone interfacing portions.

摘要： The present invention is directed to a radiolucent aiming guide for locating and drilling through the holes in the distal end of an implanted intramedullary nail. The aiming guide comprises an elongate handle (1) constructed substantially of a radiolucent material, which does not cast a strong image on a monitor when exposed to radiation. The radiolucent handle (1) is used in conjunction with a protection sleeve (20), trocar (30), drill sleeve (40), an drill bit (50), which are used to locate and drill through the hole in the nail. Radiopaque components in the distal end of the protection sleeve (20), trocar (30), and drill bit (50 are used to align the drill over the nail hole. A pair of radiopaque pins (7; 13), located within the handle (1) and lying parallel to its longitudinal axis, aid in ensuring the proper rotational alignment of the aiming guide over the nail hole. The aiming guide may also include a structure to facilitate its alignment over a second hole in the distal end of the intramedullary nail.
摘要翻译：本发明涉及一种用于定位和穿过植入髓内钉远端中的孔的射线可视瞄准引导件。瞄准引导件包括基本上由射线可透射材料构成的细长手柄（1），当暴露于辐射时，它不会在监视器上投射强烈的图像。射线透视手柄（1）与保护套（20），套管针（30），钻套（40），钻头（50）一起使用，该钻头用于定位和钻穿指甲中的孔。保护套管（20），套管针（30）和钻头（50）的远端中的不透射线部件用于将钻头对准钉孔。一对位于手柄内的不透射线销（7; 13）（1）并且平行于其纵向轴线平移，有助于确保瞄准引导件在钉孔上的适当旋转对准。瞄准引导件还可以包括便于其在髓内远端的第二孔上的对准的结构钉。

摘要： Systems, methods and device for tibial resection comprise a first cutting guide and a second cutting guide. The first cutting guide (12) 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 (34) is oriented at an angle to the first cutting guide and configured to extend generally in a posterior direction from the first cutting guide (12). The second cutting guide limits the cutting instrument in the transverse plane from cutting bone.
