Carpal Impaction with the Ulnar Styloid Process: Treatment with Partial Styloid ResectionFrom the Department of Orthopaedic Surgery and the Department of Radiology, University of Pittsburgh Medical Centre, Pittsburgh PA, USA Correspondence: Dr Matthew M. Tomaino, Department of Orthopaedic Surgery, University of Pittsburgh Medical Center, 3471 Fifth Avenue, Suite 1010, Pittsburgh PA, 15213, USA. E-mail: tomainomm{at}msx.upmc.edu Carpal impaction with the ulnar styloid process (stylocarpal impaction) occurs less frequently than with the ulnar head (ulnocarpal impaction), and more commonly develops in wrists with negative ulnar variance. Physical examination, radiographic evaluation, and wrist arthroscopy are all helpful in excluding alternative causes of ulnar wrist pain. When an ulnocarpal stress test elicits pain, and radiographs suggest that this is due to carpal impaction with the ulnar styloid, partial resection of the styloid process provides successful treatment, so long as the insertion of the triangular fibrocartilage at the base of the styloid is not disrupted.
