Isolated lesions of the radio-ulnar disk treated with excision.

Twelve patients with isolated lesions in the radio-ulnar disk are reviewed. In the traumatic cases, where peripheral ruptures were found at operation, the results after excision were satisfactory, whereas patients with no evident traumatic etiology, where a degenerated disk was found, did not benefit from the excision. Resection of capitulum ulnae is recommended in such cases.
