A novel approach to managing closed mallet finger injuries: The addition of a relative motion extension orthosis to a mallet orthosis in patients with proximal interphalangeal joint hyperextension

Disruption of the extensor tendon at the distal interphalangeal joint (DIPJ) is referred to as a mallet finger.1 Mallet finger injuries are common, with an incidence of 5.6% of all tendinous lesions in the hand and wrist.2 Whether managed surgically or non-surgically, up to 10% of cases have a poor outcome with a DIPJ extension lag greater than 10 °.3 Chronic extensor tendon lag may lead to DIPJ pain, cosmetic deformity, and functional impairment.4
