Abstract: A surgical guide for guiding and steady a saw during surgery, especially adapted to perform at least one, and preferably both, an extended trochanteric osteotomy and a trochanteric slide. The guide includes a linear slot and two slots at opposing oblique angles to the linear slot; the slots are adapted to cooperate with a surgical saw. In a preferred version, the guide is reversible so that it may be used on either a left or right leg depending on which leg the surgery is being performed on. The linear slot may be used for cutting the diaphysis of the femur and one oblique slot may be used for cutting a proximal portion of the femur, while the other oblique slot may be used for cutting a distal portion of the femur. The guide may also include a plurality of anchoring holes through which fixation pins may be inserted to secure the guide to the femur while sawing.
