Abstract: Apparatus and methods for cutting a material, especially with low material speed and high cutting torque. In some embodiments, the apparatus is a hand-held device for quietly cutting through an orthopedic cast with little or no generation of debris. In yet other embodiments, there is a method for automatically advancing material past a shearing surface, such that the shearing action occurs at about the same velocity as the advancement. In yet other embodiments, there is a device for cutting material between a foot and a sharp edge, with the bottom of the foot being under the sharp edge to protect the skin of the patient.

Abstract: Apparatus and methods for cutting through a layer of material. Some embodiments pertain to the removal of an orthopedic cast in a manner that is quiet and generates little or no particulate matter. In yet other embodiments there are a pair of toothed wheels that press down and penetrate into the cast and then split the cast by moving it past a sharp edge. In some embodiments the cutting head is reversible for the cutting of material in either of two opposite directions.

Abstract: A bone plating system to aid in tibial rotational osteotomy correction. Also, a method for correcting a long bone that has an angular misalignment.

Abstract: A comprehensive modular implant system is provided that is especially adapted for limb preservation. The modular components of the system can be combined to perform proximal, distal or total long bone replacement. Each replacement component is connected by a Morse taper engagement. The Morse taper engagement can be augmented by interlocking anti-rotation features between adjacent components. Certain components are configured to form part of a skeletal joint, while other components are configured for engagement within existing portions of the long bone. A number of segmental components operate as spacers for spanning the length of a removed section of bone. Certain segmental components are provided in several lengths, with one group of lengths increasing in 5 mm increments. Combinations of the segmental components can accommodate replacement lengths from 25 mm to 170 mm in 5 mm increments.
