Orthotic interventions for restoring proximal interphalangeal joint motion for patients with hand injuries or conditions: A systematic review and meta-analysis

•Various types of orthotic intervention exist to recover PIPJ range of motion.•Orthoses appear to be beneficial for managing traumatic PIPJ FFDs.•Orthoses do not appear to be beneficial for managing post-op Dupuytren’s release.•Limited RCT evidence exists examining “exercise orthoses” to regain PIPJ motion.•There is an absence of RCT evidence evaluating orthoses to recover PIPJ flexion.
