The Specialist Shoulder Splint aids people with humeral fractures (or as a support for after removal of internal or external fixation). The Specialist splint is made from a durable, lightweight thermoplastic that provides rigid support. Plus, it has a deltoid extension for extra protection and to prevent distal migration. The Specialist allows the shoulder full ROM. Use it on either arm. Models available for toddlers and adults in four sizes: S, M, L, & XL.
