    • Systems and methods provide patient-specific cutting blocks that allow for bone resurfacing procedures, such as milling or burring, with simplified devices. A computer assisted surgical cutting block is produced having a surface region that matches with the surface region of a patient's bone to be altered. A cutting tool may be provided having a contoured bone mating surface and a contoured and patient-specific shaped cutting guide surface, which is located in a plane above the bone mating surface. One or more channels are provided in the cutting block, and as the surgeon moves the cutting tool (a milling or burring, for example) in the channels the tool cuts the bone both laterally along the surface of the bone and vertically into the bone according to the cutting guide surface and other preselected surface features of the cutting block.
    • 系统和方法提供患者特定的切割块,其允许使用简化的装置进行骨表面修复程序,例如铣削或翻边。 产生计算机辅助外科切割块,其具有与要改变的患者骨骼的表面区域匹配的表面区域。 可以提供具有轮廓骨匹配表面和轮廓和患者特定形状的切割引导表面的切割工具,其位于骨匹配表面上方的平面中。 一个或多个通道设置在切割块中,并且当外科医生将切割工具(例如铣削或毛刺)移动到通道中时,该工具沿着骨的表面横向切割骨,并且垂直地进入骨中,根据 到切割导向面和切割块的其他预选表面特征。
