This paper introduces a newly designed dynamic traction splint for the management of digital intea-articular fractures. These fractures, particularly when involving comminution of the joint surface, often result in limitation of hand function due to joint stiffness, tendon adhesion, and chronic pain. Fourteen patients with intea-articular fractures were studied. Thirteen cases involved the proximal interphalangeal joint of the finger and one case involved the interphalangeal joint of the thumb. The splint, a compact, lateral-hinge type, was designed to apply dynamic traction to the fracture. Follow-up at 7 months (range 2 to 19 months) demonstrated functional, pain-free movement. The mean total arc of active motion was 80° in the proximal interphalangeal joints of the fingers and 60° in the interphalangeal joint of the thumb. Radiologic examination demonstrated remodeling of the articular surfaces with maintenance of joint space. The results, when compared with those of other treatment methods, support the use of this splint and treatment program for the management of difficult intea-articular fractures.
