人体上肢肌肉的基本解剖学和生理学特性已经阐明了使用一种新的术中肌节长度测量装置结合这些相同的肌肉的定量解剖学和生物力学模型。我们回顾了这些研究的起源，这些研究始于光学工具的发展，使用动物模型的验证，以及在人类上肢手术中的应用。人类的肌肉有一个显着的专业化程度，即使在协同。人类肌腱的机械特性提供了另一个特化来源，使得肌肉-肌腱单元不简单地保留肌肉加肌腱的特性。不同肌肉的操作范围也是一种方法，由此可以在面对改变的力矩臂和肌肉力时保持关节的平衡。这些原则的推导解释沿着与他们的重要性，在外科肌腱转移，其中一个肌肉替代另一个功能。
The basic anatomic and physiologic properties of human upper extremity muscles have been elucidated using a novel intraoperative sarcomere length measuring device in conjunction with quantitative anatomic and biomechanic models of these same muscles. We reviewed the genesis of these studies which began with development of the optical tools, validation using animal models, and application to human upper extremity surgery. Human muscles have a remarkable degree of specialization, even among synergists. Mechanical properties of human tendons provide another source of specialization such that the muscle-tendon unit does not simply retain the properties of a muscle plus a tendon. The operating range of different muscles is also a method whereby the balance of the joint can be maintained in the face of altered moment arms and muscle forces. The derivation of these principles is explained along with their importance in surgical tendon transfers where one muscle substitutes function for another.
