Figure Legend: Scaphoid nonunion eventually leads to progressive wrist arthritis in many patients.  Uncommonly, nonunion may be the site of infection.  This patient had undergone open reduction of a scaphoid fracture, and by history had a pin tract infection of one of the Kirschner wires used for scaphoid fixation, requiring early removal by the first surgeon.  He presented over a year later with an abscess at the site of the prior pin tract infection, tracking deep to an infected scaphoid nonunion. Infection control involved radical debridement, including a proximal row carpectomy.
