ABSTRACT:
The device is a diagnostic tool for the determination of the functional loss of the collateral ligaments of the elbow. The device serves to position and to stabilize the arm of a subject and to position the elbow in a predetermined fixed position to allow for X-raying of elbow joints under graded pressure. A first part of the device is a unit for receiving a hand and securing the wrist in a predetermined position. The hand receiving member has a planar upright support section which has a plurality of spaced holes. Preferably, the spaced holes are arranged in a plurality of parallel rows. The first part includes a first rod shaped member or roller positioned in a hole such that it is contacted by the palm of the hand, with the palm upward in supination. The wrist is secured to a second rod or roller mounted in another of the holes, to hold the wrist in a predetermined position relative to the second roller. A third roller is provided such that the wrist is locked in position between the second and third rollers. Each of the plurality of hand securing rollers are positionable in the spaced holes so as to be adjustable relative to each other so as to receive a hand and wrist and to secure the hand and wrist in a predetermined supination position. A vertical post is provided for bracing the shoulder and a pressure mechanism applies pressure to the radiohumeral joint to elicit widening of the medial joint space.
