SLAC wristに対してfour-corner fusionを施行した2例

SLAC Wrist Treated by Scaphoid Excision and Four-Corner Fusion : Report of Two Cases

　抄録：Scapholunate advanced collapse（以下SLAC）wristに対して舟状骨切除とfour-corner fusionを施行した報告は少ない．今回，われわれは2例のSLAC wristに対して本術式を施行した．症例は51歳の男性と70歳の男性である．それぞれ右手関節痛および左手関節痛を主訴に当科を受診し，Krakauerの分類で2期および3期のSLAC wristと診断した．2例とも舟状骨切除とfour-corner fusionを併用した術式を施行し，痛みは消失して本人は満足している．舟状骨切除とfour-corner fusionを組み合わせた術式は，2期および3期のSLAC wristに対して選択し得る方法と考えられる．

　We report two cases of scapholunate advanced collapse (SLAC) wrist treated by scaphoid excision and four-corner fusion. Case 1：A 51-year-old man presented with a 1-year history of right wrist pain. Radiographs showed SLAC wrist, stage 2, and scaphoid excision and four-corner fusion were performed. Twenty-four months after surgery, the patient had no wrist pain and was satisfied with the results. Case 2：A 70-year-old man presented with a several-year history of left wrist pain. Radiographs showed SLAC wrist, stage 3, and scaphoid excision and four-corner fusion were performed. Ten months after surgery, the patient had no wrist pain and was satisfied with the results. Scaphoid excision with four-corner fusion seemed to be a valid option for surgical treatment of stage 2 and 3 SLAC wrist.
