Abstract
Abstract A bracelet-like appliance for the treatment or prevention of carpal tunnel syndrome includes a C-shaped member having a central portion located over the dorsal side of the wrist and two arms encircling the wrist. Each arm has a pad for engaging the palm near the attachment edges of the carpal ligament at the medial border and the lateral border of the carpal bones. The bracelet also includes a pad attached to the central portion for engaging the dorsal part of the wrist. The member is shaped to cause the pad attached to the central portion to press against the dorsal side of the wrist while the ends of each arm press in the opposite direction on the edges of the palm. The C-shaped member is a single piece of resilient, malleable material, such as aluminum, or is divided into sections interconnected by spring loaded hinges.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
163 words
An orthopedic appliance for the treatment or prevention of carpal tunnel syndrome by slowly and gently stretching the transverse carpal ligament over a period of several hours, said appliance comprising: a C-shaped member having a central portion, a first arm extending in a first direction from said central portion to a free end, and a second arm extending in a second direction, opposite the first, from said central portion to a free end; a first pad attached near the free end on the interior of said first arm; a second pad attached near the free end on the interior of said second arm; a third pad attached to the interior of said central portion; wherein, when said appliance is worn on a wrist, said third pad presses upon a dorsal part of the wrist while said first pad and said second pad press in the opposite direction on the edges of the palm to flatten the palm and stretch the transverse carpal ligament.
