Abstract: An anatomic femoral guide positions bone tunnels corresponding to the AM and PL bundles in ACL repair and reconstruction procedures. A template guide disposed in a surgical field proximate to a surgical member such as a femur or tibia defines a surgical footprint of the resulting bone tunnel. The template includes apertures corresponding to the size of the bone tunnels for the respective (AM or PL) bundles, and allows positioning at the drilling site to identify the size and location of the bone tunnel, as well as the relative distance between tunnels for double bundle procedures. An offset angle in the template provides differing orientations of the template apertures for visualizing the actual bone tunnel placement. The template has an aperture positionable parallel to a tibial plateau formation on the tibia, and the template orients a second aperture angled by the offset angle for positioning the second tunnel.

Abstract: Methods and devices that displace bone or other hard tissue to create a cavity in the tissue. Where such methods and devices rely on a driving mechanism for providing moving of the device to form a profile that improves displacement of the tissue. These methods and devices also allow for creating a path or cavity in bone for insertion of bone cement or other filler to treat a fracture or other condition in the bone. The features relating to the methods and devices described herein can be applied in any region of bone or hard tissue where the tissue or bone is displaced to define a bore or cavity instead of being extracted from the body such as during a drilling or ablation procedure.

Abstract: A cleaning module for cleaning bone stock used in surgical procedures. The cleaning module includes a shell. The shell defines a void space to receive the bone stock. A cutter is rotating mounted in the void space. A shaving tube, also able to rotate, is coaxially disposed about the cutter. The cutter and shaving tube have complementary edges. A drive assembly rotates the cutter and shaving tube at different speeds, at different times or in different directions relative to the cutter. As a result of the rotation of the cutter and shaving tube soft tissue adhering to the bone stock is cut away from the bone stock by the relative rotating of the cutting edges of the cutter and shaving tube.
