Abstract
A hinged limb immobilizer device for setting and securely maintaining a predefined range of motion for a limb, requires no special tools for installation or adjustment. Limit stops are adjusted by simply loosening the appropriate thumbscrew, and moving the limit stop to the prescribed setting. Separate color-coded, labelled scales for flexion and extension match-up with separate color-coded thumbscrews to avoid misunderstandings. Security of adjustment is optimized by limit stops which embody both friction stop and positive stop characteristics, resulting in a unique 'three-point locking' mechanism.
