ABSTRACT:
Improved bone cutting guides enable a surgeon to better gauge required resection characteristics. In one embodiment at least a portion of the guide is transparent, thereby enabling the user to optimize cut estimates and to visualize the resection as it is being performed. In another embodiment, at least a portion of the outer surface of the body is shaped to interact with another bone or prosthetic element associated with a joint, thereby enabling the device to function both as a trial and as a cutting guide. In this embodiment as well the guide may be at least partially transparent to improve visualization. Although primarily intended for use in femoral-side knee arthroplasty, the invention is applicable to any procedure which might benefit from improved bone-cutting accuracy.
