For the extrinsic hand flexors (flexor digitorum profundus, FDP; flexor digitorum superficialis, FDS; flexor pollicis longus, FPL), moment arm corresponds to the tendon's distance from the center of the metacarpalphalangeal (MP), proximal interphalangeal (PIP), or distal interphalangeal (DIP) joint. The clinical value of establishing accurate moment arms has been highlighted for biomechanical modeling, the development of robotic hands, designing rehabilitation protocols, and repairing flexor tendon pulleys (Brand et al., 1975; An et al., 1983; Thompson and Giurintano, 1989; Deshpande et al., 2010; Wu et al., 2010). In this study, we define the moment arms for all of the extrinsic flexor tendons of the hand across all digital joints for all digits in cadaveric hands.
对于外在手部屈肌（深指屈肌、FDS；浅指屈肌、FPL；拇长屈肌、FPL），力臂对应于肌腱距掌指（MP）、近指间（PIP）或远指间（DIP）关节的距离。建立准确力臂的临床价值已在生物力学建模、机器人手的开发、康复方案设计和修复屈肌腱滑车（Brand 等人，1975 年；An 等人，1983 年；Thompson 和 Giurintano，1989 年；Deshpande 等人，2010 年；Wu 等人，2010 年）方面得到了强调。在这项研究中，我们定义了尸体手上所有手指的所有外在屈肌腱在所有手指的所有数字关节上的力臂。
