A novel splint for proximal interphalangeal joint contractures: a case report

Wollstein R, Rodgers J, Ogden T, Loeffler J, Pearlman J. A novel splint for proximal interphalangeal joint contractures: a case report. Proximal interphalangeal (PIP) joint contractures are notoriously difficult to treat. Best results are obtained with early mobilization and splinting, though a high level of adherence is critical for a good outcome. A new roll-on splint that aims to increase motion with minimal difficulty was used. The patient described here with moderate PIP joint contractures (30°-60°) was treated successfully using this splint. The splint design and therapy protocol are described. The patient was treated for 12 weeks with good adherence to therapy and splinting. Total active motion increased by 87% in the index finger and 108% in the ring finger. Grip, pinch, and tip-pinch strengths increased. The Disabilities of the Arm, Shoulder and Hand score improved from 26.7% to 2.5%. At 3 months, the patient returned to work. Though this case illustrates some of the advantages and disadvantages of the new splint, further study is necessary to evaluate the splint and compare it with other existing forms of treatment for PIP joint contractures.
