Capitate Fracture with Scapholunate Ligament Rupture: A Case Report

Capitate fractures are rare, accounting for 1-2% of all carpal fractures, and are frequently associated with high-energy trauma. When accompanied by scapholunate ligament rupture, the injury becomes significantly more complex with increased risk of instability, non-union, chronic instability. We report the case of a 36-year-old male police officer who sustained a high-energy wrist injury following a motorcycle accident. Imaging revealed a displaced transverse capitate fracture (AO 73A) with an associated scapholunate ligament rupture. The patient underwent open reduction and internal fixation (ORIF) of the capitate using a headless screw with ligament repair and dorsal capsular imbrication. Early postoperative rehabilitation was initiated with a structured and progressive program. At 10 weeks post-surgery, the patient demonstrated near-normal wrist function, range of motion, and grip strength. Radiographic follow-up confirmed fracture union and maintained carpal alignment. The patient successfully resumed full occupation duties without functional limitations. This case highlights the importance of timely diagnosis and comprehensive surgical management in complex carpal injuries involving both bony and ligamentous structures. Early mobilisation and a structured rehabilitation program played a pivotal role in achieving excellent functional outcomes, emphasising the critical integration of surgical and post-operative care in managing such injuries.
