Low Profile Extension Splint for Active Extensor Lag of the Proximal Interphalangeal Joint

Typically when treating digit injuries, the focus is on flexion. This is the desired motion needed for most activities of daily living. However, when a digit does not have full extension patients will frequently complain that their finger catches on things such as when reaching in a small drawer, getting into their purse, and or reaching into a pocket. When we attempt to correct this loss with a high profile splint the same situation can occur. Thus, the patient once again is not using his or her finger during functional activities. This author has designed a low profile splint that helps to improve proximal interphalangeal joint extension lag and to encourage functional use of the hand.— Peggy Fillion, OTR, CHT, Practice Forum Editor
