[Tension force in dynamic splints made of neoprene].
Dynamic splints are the most difficult ortheses to make. Unrestricted finger joint mobility is usually prevented by the size of their components. Ortheses made out of neoprene material have the advantage of being pliable and at the same time can be constructed as dynamic splints. Neoprene material elasticity allows conforming it into a tube that can be fitted over a finger, spreading uniform pressure. A traction slip can be cemented to the neoprene finger tube. With neoprene splints, lever arms are more efficient. Their tubular design applies and spreads traction and countertraction forces in all directions. Neoprene material's elasticity contributes in reducing edema formation as well as distributes forces applied to the finger over a large area. The risk of excessive pressure is the only drawback of an elastic tubular design, it may cause pain and tissue ischemia. A meticulous tailoring prevents this potential risk.
