eSplint Humerus stabilizes the upper arm after humerus fracture. The design of the orthosis makes it easy to apply and adjust around the upper arm. The internal plates around the arm and the circular straps provide compression and pain relief. The plates are stable and compliant for a good fit and can be adjusted with scissors if necessary or partially removed if less stability is desired. If the orthosis is large in circumference, the thin plates can be removed to give less circumference around the arm. The orthosis is comfortable to wear and both arm and chest straps are adjustable. The product is MR compatible.
