Abstract: The invention provides for a spinal fixation support device to be used in conjunction with spinal fixation instrumentation. The invention further provides for methods of using the spinal fixation support device. In addition, the invention provides for a spinal fixation system that includes a spinal fixation support device of the invention and can further include spinal fixation instrumentation.

Abstract: A spinal fixation system and methods are provided that includes a plurality of pillars each positioned through a compromised vertebra and into the lower or upper endplates of the neighboring healthy vertebrae.

Abstract: Disclosed is a method and apparatus for repeatably positioning a forearm at a plurality of angular positions for medical analysis. A forearm of a patient is positioned in a support channel within reach of a rotatable handle. The handle can be locked in a number of angular positions, providing a counteractive force as the handle is rotated. The patient rotates and applies a torque force to the handle at selected rotational angles. The forearm and wrist can be scanned in these locked position, and applied torque can be measured to evaluate joint stability.

Abstract: A prosthesis for the radius bone in the arm of a patient includes a head shaped for engagement with the capitellum of a humerus bone and the radial notch of the ulna. It also has a curved stem that extends from the head and is tapered with a distally decreasing cross section for insertion into the medullary canal of the radius. A system for implanting the prosthesis requires a resection guide for placing the forearm of the patient in a precise anatomical orientation for resection of the radius bone. The resection guide includes a notched alignment rod attached to an adjustable flange and a reference flange for aligning the forearm for a cut of the radius bone perpendicular with the axis of rotation of the radius bone about the ulna, and for measuring the size of the resection and prosthesis.
