This study is to determine function following simulated thumb metacarpophalangeal (MP) and thumb interphalangeal (IP) joint fusion. The investigators want to determine the functional limitation created by MP and IP joint fusion. 20-30 volunteers will be fitted for custom molded orthoplast splints immobilizing either the MP or IP joint. The volunteers will then be taken through multiple tests including lateral pinch strength, tip pinch, grip strength, grooved pegboard test time, and Jebson Taylor test. Each patient will be tested without a splint, with their MP joint immobilized and with their IP joint immobilized. The results of this study can be used for patient education before surgery in order to help them make informed decisions as well as manage expectations. It can also serve as a decision aid in pinch restoration in the context of ulnar nerve palsy.

consists of seven test items, which are felt to represent various hand activities. These test items include: writing a short sentence; turning over 365 inch cards; picking up small objects and placing in a container; stacking checkers; simulated eating; moving empty large cans; and moving weighted large cans.
Measured in every splint position using a standard dynamometer
Time will be measured and compared between control, MP splint and IP splint
