Abstract:
To create a novel kind of orthosis to correct the dysfunction of antebrachium, wrist, metacarpus and digit and to facilitate the protection and functional training after injury of forearm and hand. The orthosis is constituted of a cardinal shelf, a stem shelf of metacarpophalangeal joint, a front bracket, finger ferrules, elastic strings and steel wires. The cardinal shelf is composed of a backplate for dorsal palm and a bracket for wrist with a U-shaped rack fixed in front of it. Ferrules of index finger, middle finger and fourth finger and little finger are connected to the backplate on the cardinal shelf through elastic strings. The thumb ferrule is set outside the ferrule of index finger on the backplate with steel wires. Another ferrule that is used to enclose the wrist and antebrachium is linked to the crossbar of the U-shaped rack through elastic strings. This orthosis plays an effective role in the protection of nerves, tendons, extremity of vascular anastomosis and the prevention of allotopia after fracture due to different trainings. It can improve the range of motion of wrist joint, metacarpophalangeal joint, and articulationes interphalangeae and strengthen the muscle power of pronator teres, pronator quadratus, supinator, wrist extensor, wrist flexor, extensor digitoium, perforans manus and musculus flexor digitorum sublimes. This orthosis could be applied for patients after the operation of antebrachium,wrist and manus to promote the recovery of their functions.
