It occurs when the aponeurosis of the adductor pollicis muscle becomes interposed between the ruptured ulnar collateral ligament (UCL) of the thumb and its site of insertion at the base of the proximal phalanx. No longer in contact with its insertion site, the UCL cannot spontaneously heal. ==Gamekeeper's thumb: history and mechanism of injury== (詳細はgamekeeper's thumb in 1955, after he observed this condition in a number of Scottish gamekeepers.〔Campbell CS. Gamekeeper's thumb. J Bone Joint Surg Br. Feb 1955;37-B(1):148-9.〕 The injury appeared to occur as a result of the particular manner in which they killed small animals such as rabbits. Specifically, the animals were placed on the ground, and their necks were broken as the gamekeeper exerted downward pressure with the thumb and index fingers. This maneuver would place a valgus force upon the abducted metacarpophalangeal (MCP) joint. Over time, this would lead to insufficiency of the ulnar collateral ligament of the thumb, a condition which Campbell referred to as ''gamekeeper's thumb''. In 1962, Bertil Stener described a lesion which he observed to occur in a subset of patients suffering from gamekeeper's thumb. In these patients, the distal attachment of the UCL was traumatically avulsed from its site of insertion at the base of the proximal phalanx of the thumb. The severed end of the ligament would become trapped under the aponeurosis of the adductor pollicis muscle and therefore be unable to return to its proper anatomic position. Consequently, the severed ligament would fold on itself and thus be prevented from healing and restoring stability to the MCP joint.〔Stener B. Displacement of the ruptured ulnar collateral ligament of the metacarpophalangeal joint. J Bone Joint Surg Am. Nov 1962;44B(4):869-79.〕 For a Stener lesion to occur, both the proper and accessory collateral ligaments of the thumb must be completely ruptured. The Stener lesion is present in more than 80% of complete ruptures of the UCL of the thumb. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Stener lesion」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
