title: A prospective randomized study of conservative versus surgical treatment of unstable palmar plate disruption in the proximal interphalangeal finger joint.
abstract: The aim of this study was to assess the effect of conservative versus operative treatment for unstable palmar plate disruption in the proximal interphalangeal (PIP) joint of the fingers with respect to preservation of joint stability, mobility, and pain. The study was conducted as a prospective study in which 83 patients were randomly assigned into 2 groups: (1) conservative treatment with a rigid splint for 2 weeks, (2) surgical reattachment of the palmar plate in local anesthesia followed by 2 weeks of immobilization in a plaster cast. Both groups were thereafter treated by taping to the neighboring finger for 3 weeks. With regard to hyperextension instability, stiffness, and pain, there is no significant difference in outcome between patients with traumatic palmar plate lesions and hyperextension instability treated with surgical repair and patients treated conservatively with a splint. We do not recommend primary surgical repair of unstable isolated palmar plate lesions in the proximal interphalangeal joints of the 4 ulnar fingers. Type of study/level of evidence Therapeutic, Level II.
