Apparatus to correct restricted mobility especially at the elbow has sprung carrier disks with flexion and extension stops with a simple and rapid adjustment of their rotating ranges

摘要

The apparatus to correct joint movement deficiencies, and especially at the elbow, has a spring mechanism which acts in the flexion and reduction directions. A rail is attached to each section of the limb flanking the joint, and the apparatus has adjustable limits to set the pivoting area between the rails. A flexion stop carrier disk carries a flexion stop (26), and an extension stop carrier disk (29) has an extension stop (27). Clamping rings (30) define the rotation ranges of the carrier disks (29) in a blocking action. When the system is not blocked, the stops (26,27) can be moved to the required limits of their rotation by a stop carrier.
