Carpometacarpal Thumb Arthritis is a disease caused by different factors and attacks mainly woman older than 50 years. The signs and symptoms consist in pain, swelling, joint instability, deformity and loss of motion. Some evidence has shown that splinting of the thumb may be of benefit. There are two methods of splinting: The first is Standard Neoprene wrap-on thumb support (in which the finger is kept in the same position with in a standard Neoprene thumb splint). The second is Thermoplast Short Opponens splint (This splint is custom-made and the thumb is use as a template to design the splint). The purpose of this study is to test and evaluate these two protocols of splinting and assess which one helps or works better in patients with thumb arthritis.
