三角肌攣縮手術治療對肩關節肌力之影響

The Effect of Surgical Intervention for Deltoid Contracture on Isokinetic Shoulder Muscle Strength

摘要


肩關節三角肌攣縮造成肩關節活動的內收與前屈受到限制,其原因來自於三角肌經重複肌肉注射而產生的病變纖維化。治療處理上以手術為主,方法分為近位縱切、近位橫切、遠端切除等。手術處理主要可解除使肩關節活動限制的纖維化組識,進一步也解除因活動受限所導致的肩痛現象。由於手術切除的組織為肩三角肌,因此有影響肩關節外展肌力之虞。本研究的目的為以等速肌力測試來評估遠端切除之手術方法對肩關節肌力的影響。結果顯示後伸於低速測驗以及前屈於快速測驗中在術後1年有明顯進步,其餘動作則皆未有明顯影響。

Deltoid contracture is a disorder which may result from repeated intramuscular injections. The clinical manifestations consist of restriction of shoulder adduction, shoulder pain, and wing scapula. Surgical intervention is a most utilized way to resolve the problem of limited range of motions, which includes proximal transverse incision, proximal longitudunal incision, and distal release technique developed by Dr. Chen, one of the authors. Objective isokinetic muscle testing proved the distal release of deltoid contracture did not affect the shoulder muscle strength.
