Orthotic Management of CMC Osteoarthritis

This study will investigate the effectiveness of 3D printed splints for the treatment of thumb osteoarthritis (CMC OA). Currently, these splints are made by Occupational Therapists and Physical Therapists out of low temperature plastic, and formed on the patient's hand. 3D printed splints involve taking a photographic scan of the hand and creating a digital file of the splint. This is then printed and fit on the patient. This study will compare the effectiveness of these methods of splint fabrication. Our outcomes will include measurements of pain relief, adherence, patient satisfaction, muscle contraction and CT imaging during pinch tasks to measure the ability of these splint types to support the CMC joint.
