Background and Aim: Headless cannulated compression screw is often used in scaphoid fracture and nonunion surgery. In the volar and dorsal surgical approach, when adequate fluoroscopic imaging is not performed, the screw may protrude beyond the scaphoid bone and penetrate into the joint. When the length of the screw is too long, and it is noticed intraoperatively, it is replaced with a shorter screw. However, there is no clear consensus in the literature about the way to be followed when screw penetration is noticed in the postoperative period. Materials and Methods: The cases in which cannulated screw penetrated the radioscaphoid, scapholunate, and scaphotrapeziotrapezoid joint on postoperative radiographs were included in this study. Sixteen patients (13 men and 3 women) were included. The mean postoperative follow up time was 35.1 months. There was scaphotrapeziotrapezoid joint penetration in seven cases, scapholunate joint penetration in two cases, and radioscaphoid joint penetration in seven cases. Results: Osteoarthritis developed in the scapholunate joint in two cases and in the radioscaphoid joint in two cases. Early revision surgery or waiting for the fracture to heal and removing the screw, or not performing secondary surgery are among the options. In this study, mid term radiological results of screws penetrating radioscaphoid, scapholunate, and scaphotrapeziotrapezoid joints were examined. It was observed that it may cause osteoarthritis development in radioscaphoid and scapholunate joints, but it did not cause osteoarthritis development in scaphotrapeziotrapezoid joint. Conclusion: In the early postoperative period, revision surgery is recommended to prevent the development of osteoarthritis of screws penetrating the radioscaphoid and scapholunate joint.
