Wrist Arthroscopy-Assisted Coronal Hamate Fracture Treatment.

Objective: We present a case of wrist arthroscopy-assisted fracture treatment in a 39-year-old patient who underwent surgery for a coronal hamate fracture. Methods: We performed intraoperative closed reduction and percutaneous headless screw fixation under arthroscopic guidance in a patient with a coronal fracture of the right hamate body and dislocation of the 5th carpometacarpal joint due to a fall. Dislocation reduction was achieved by applying traction to the fingers on the arthroscopy tower, and the fracture was visualized with a hook during compression under direct arthroscopic visualization. Results: Although arthroscopy-assisted fracture treatments are frequently applied in larger joints, they are less common in smaller joints such as the carpal joints. Wrist arthroscopy, which requires experience, can yield successful results by enabling clear visualization of the joint and the fracture line in cases like coronal fracture-dislocation. Additionally, it encourages surgeons to perform closed fixation in selected cases and minimizes the risks associated with open surgery. Conclusion: Arthroscopy-assisted surgery for coronal hamate fractures provides advantages such as less soft tissue dissection and anatomical reduction, but it requires experience in wrist arthroscopy.
