Finger Orthosis – Hand splints are commonly used to immobilize the hand and fingers after injury. Custom splints are made from low-temperature thermoplastic materials. Mechanical principles must be followed when splinting the hand to ensure that the forces and stresses are correct. There are four types of hand splints: static, dynamic, serial static and static progressive. Static splints hold the hand in one position and are typically used during the immobilization phase of healing to decrease pain and prevent movement. Dynamic splints are used to improve motion — or mobilize tissue in the hand. Serial static and static progressive splints hold structures in a stretched position. As flexibility increases, these splints are remoulded to stretch the tissues in the new position.
