AbstractThe aim of this prospective study was to determine whether peripheral tears of the triangular fibrocartilage complex (TFCC) in patients younger than the osteoporotic age (males,<60 years; females, <50 years) were related to chronic distal radioulnar joint (DRUJ) instability. Fifty-one patients (27 women) with displaced distal radial fractures were included in the study. The median age was 41 years (range, 20-57 years). Arthroscopy at the time of fracture showed complete or partial TFCC tears in 43 patients (24 had only peripheral tears, 10 had only central perforations, and 9 had combined tears). The 1-year (range, 11-27 months) follow-up period included an interview, physical examination, and radiographic evaluation. Ten of the 11 patients with complete peripheral TFCC tears had DRUJ instability at the follow-up examination compared with 7 of the 32 patients with only partial or no peripheral tears. Patients with instability of the DRUJ had a worse Gartland and Werley wrist score. Instability was not associated with any radiographic finding either at the time of fracture or at the follow-up examination. Initial fracture or nonunion of the styloid was even slightly more common in stable patients.
