Triquetral fracture with associated pisiform subluxation.

We herein present a case of right triquetral fracture with associated pisiform and flexor carpi ulnaris subluxation in a 29-year-old man. Initial radiography showed a right triquetral fracture. Computed tomography and magnetic resonance imaging demonstrated a triquetral fracture with a subluxated pisiform. Open reduction and lag screw fixation of the right triquetrum was performed, with good subsequent recovery of function. Although triquetral fracture with subluxation of the pisotriquetral joint is uncommon, attending clinicians should bear in mind the possibility of such an injury when managing traumatic ulnar-sided wrist pain.
