Ulnar-sided wrist pain due to isolated disk tear of triangular fibrocartilage complex within the distal radioulnar joint: two case reports.

Abstract
Wrist arthroscopy has been successfully used with many modifications and improvements. However, distal radioulnar joint (DRUJ) arthroscopy is still uncommon. We experienced 2 cases of ulnar-sided wrist pain due to isolated triangular fibrocartilage complex (TFCC) disk tear within the DRUJ. DRUJ arthroscopy in these cases showed horizontal tear and fibrillation of TFCC disk without TFCC tear at the radiocarpal joint. Foveal attachment was intact in both cases. These were treated with debridement, which relieved pain after surgery and achieved good functional recovery. Although DRUJ arthroscopy is technically difficult, it is mandatory for making a diagnosis and treating ulnar-sided wrist pain.
