Abstract: An instrument for aligning an x-ray beam relative to an x-ray film and a target tooth of an animal patient. The instrument orients the beam relative to the film, to produce dental radiographs of the target tooth in accordance with the bisecting-angle technique. More specifically, the instrument includes an alignment tool configured to align a longitudinal axis of the x-ray beam orthogonal to a bisecting plane lying approximately midway between a target plane defined by the target tooth, and an x-ray film plane defined by the x-ray film. In some embodiments, the instrument may also include an x-ray film holder and an x-ray film holder support, allowing the film to be conveniently positioned and held in proper alignment during an x-ray procedure.

Abstract: A veterinary appliance for use on a selected front leg of a small animal, such as a canine or feline, to isolate the leg includes a brace detachably mountable on the leg for limiting the extent to which the ulnar portion of the leg may be bent toward its associated humeral portion. The brace nonetheless permits substantially unconstrained movement of the leg to an extended position. Additionally, the brace includes a first section which is mountable on the ulnar portion and a second section connected thereto which is configured to engage the humeral portion and transfer a reactive force to the first section and correspondingly to the ulnar portion to prevent further bending toward the humeral portion after bending to a predetermined angular position has occurred.
