We investigated the relationship between stress applied in several positions of the wrist and pain intensity in triangular fibrocartilage lesions in sixty-one patients who were diagnosed as having triangular fibrocartilage lesions and had a wrist arthroscopy. Before arthroscopy, we stressed the wrist with an axial load applied in four different wrist positions, and the evoked pain was graded into four levels. The patients who had a triangular fibrocartilage lesion on arthroscopy were divided into those with a traumatic tear and those with degenerative changes. While hypersupination and extension of wrist position evoked the most severe pain in patients with a traumatic tear, the intensity of pain did not relate to wrist rotation in patients with degenerative changes.
