手関節ＴＦＣＣ損傷：鏡視下手術の成績 （第２報）

Abstract

Ten patients with traumatic TFCC perforations and six patients with degenerative TFCC perforations (ulnocarpal abutment syndrome) were treated with arthroscopic partial TFCC resections, and five patients with ulnocarpal abutment syndrome were treated with arthroscopic ulnar head resection. All patients with traumatic TFCC perforations and small degenerative perforations, which were early phase of ulnocarpal abutment syndrome, had good result by arthroscopic partial TFCC resection. They acquired almost full ROM and grasping power, and had no wrist pain. In the cases with arthroscopic ulnar head resection, the patients whose ulnar variance were less than 2mm had good result, but in the more advanced cases, the wrist pain did not decrease.The arthroscopic surgery is a less invasive thchnique, and produces good results in the case of TFCC perforations and ulnocarpal abutment syndrome.
