Description

The extension splint for the distal interphalageal (DIP) joint is for use in Mallet Finger injuries. This injury occurs when a force is directed at the distal finger resulting in an avulsion of the extensor tendon from the dorsum of the base of the distal phalanx. Currently there are several splints on the market that are used with this injury. Patient compliance is an issue that greatly effects the outcome after treating these injuries. The splint must be left in place for 6-8 weeks without removal. However, many patients remove these splints before the injury has healed for several reasons, ranging from not knowing that the splint should stay in place for 6-8 weeks to wishing to wash the finger. Early removal may result in failed healing and deformity. This new splint is different than other splints in that it slides on as a ring just proximal to the DIP and attaches to the finder nail by an adhesive connection. This design allows for increased compliance, use of the finger tip sensation, and washing of the finger. In addition, tape is not used to hold the splint on the finger, thus reducing the possibility of allergic reaction.
