Wafer distal ulna resection for triangular fibrocartilage tears and/or ulna impaction syndrome.
Partial resection of the distal ulna (wafer resection) has been used to treat patients with symptomatic tears of the triangular fibrocartilage complex or mild ulna impaction syndrome. In this procedure, the distal 2 to 4 mm of the distal ulnar head is resected while preserving the ulnar styloid process and the ligaments attached to it. The triangular fibrocartilage is debrided, repaired, or partially excised as necessary. The procedure is contraindicated if there is more than 4 mm of positive ulnar variance. Thirteen wafer resections of the distal ulna were performed in 12 patients. All had good to excellent results after a minimum follow-up of 1 year. Wafer resection has specific advantages and avoids many of the potential complications of distal ulna recession and ulnar head resection for patients with the conditions described. The procedure is not indicated if instability or degenerative arthritis of the distal radioulnar joint is present or if there is carpal instability.
