DIP and PIP joint injuries, resulting from hyperextension or dorsal fracture dislocation, present a significant challenge in assessment and treatment. The potential for irreparable damage emphasizes the critical need for precise and effective treatment strategies. The proposed study aims to investigate dynamic splinting techniques and their clinical outcomes for DIP and PIP joint injuries, with a focus on optimizing patient outcomes and minimizing long-term consequences. A literature search in Medline, Cochrane, PubMed, Embase, and Scopus databases was conducted using terms like ‘PIP injuries’, ‘DIP injuries’, ‘Dynamic Splints’, ‘Extension Block Splint’, ‘Finger Injuries’, and ‘Hand Injuries’. Full-text analysis was performed on 11 articles. Dynamic splinting approaches, including assist and extension splints, have been demonstrated to enhance range of motion (ROM) and facilitate rehabilitation in a variety of DIP and PIP joint ailments, such as fracture subluxation, dislocation, and hyperextension. Active motion exercise, combined with splinting, consistently produced positive results. The proposed study examined the challenges associated with assessing and treating hand joint injuries, specifically those resulting from hyperextension or dorsal fracture dislocation, and the importance of dynamic splinting techniques in addressing these challenges. Overall, this review seeks to enhance the understanding of dynamic splinting’s contributions to the rehabilitation of finger injuries.
