 Collateral ligament shortening causes extension contractures of the metacarpophalangeal (MCP) joint, and dynamic flexion splinting (DFS) has been widely used to treat these contractures. However, extension contractures associated with bent MCP joints are not only ineffectively treated using DFS, the treatment may also lead to articular cartilage damage. We developed a novel pneumatic-type dynamic traction and flexion (DTF) splint using an artificial pneumatic muscle and MCP joints and applied it in two cases one day after undergoing surgically released extension contractures. The ROM of the DTF post-operative patients was compared with that of Continuous Passive Motion (CPM) therapy only during exercise and during self-training. The results indicate that as for DTF, the ROM of the DTF patients was equal to or exceeded that of the patients who used only CPM. Furthermore, DTF orthosis reduced the time needed to improve the ROM more than other methods. The results indicate that DTF is a useful splint to improve ROM after surgery.
