Arthroscopic Technique of Wafer Resection

Ulnar impaction syndrome, also called ulnocarpal abutment syndrome, is one of the most common causes of ulnar-sided wrist pain in the presence of a normal or positive variance of the distal ulnar head. Usually, it is associated with degeneration of the triangular fibrocartilage complex. This condition is commonly treated by debridement of the central part of the triangular fibrocartilage complex ligament followed by a wafer resection of the ulnar head. Alternative surgeries are wafer resection preserving an intact triangular fibrocartilage complex ligament and an inverted wafer resection corresponding to a lunate and triquetrum proximal resection with luno-triquetral ligament debridement
