Abstract
There are disclosed systems and methods for safely and effectively removing the articular cartilage and cortical bone layers from an articular surface of a human cadaveric femoral head. One embodiment includes an osseous-sanding accessory system installed upon a conventional band saw having a motor and a cabinet that houses a pulley coupled with a primary drive shaft rotated by the motor. The accessory system may include a threaded drive shaft coupled with the primary drive shaft, a grinding disk having an abrasive surface and affixed about a distal end of the threaded drive shaft, and a removable accessory table mounted to the band saw below the grinding disk. When the motor rotates the primary drive shaft, and thus the threaded drive shaft, the grinding disk rotates relative to the accessory table and abrades osseous tissues introduced to the abrasive surface of the grinding disk. Other embodiments are also disclosed.
