Joining tendon's inextensibility with joint's mobility, a tenodesis fixes on the bones the two ends of a tendon on both sides of one or several joints. A "simple" tenodesis overrides only one joint, whereas a "dynamic" tenodesis crosses two or more joints. A "crossed" dynamic tenodesis crosses the line which joins rotation axes. A "direct" dynamic tenodesis is located on the same side of this line. The "tenodesis effect" is normally produced by the movements of the joint on the neighbouring tendons. Anatomical examples are given by the oblique retinacular ligaments (crossed dynamic tenodesis), and by the tenodesis effects linked to the flexion-extension of the wrist on the extrinsic tendons of the fingers (direct tenodesis effect), or to the flexion-extension of the PIP joints on the intrinsic tendons of the fingers (crossed tenodesis effect). Main tenodesis techniques are used for palliative surgery in paralysis of EDC, intrinsic muscles of the fingers, or extrinsic muscles of the thumb (EPL, FPL, APL and EPB).
通过将肌腱的不可伸展性与关节的可动性相结合，腱固定术将一条肌腱的两端固定在一个或多个关节两侧的骨头上。“单纯性”腱固定术仅跨过一个关节，而“动力性”腱固定术则跨过两个或更多关节。“交叉性”动力性腱固定术跨过连接旋转轴的线。“直接性”动力性腱固定术位于这条线的同一侧。“腱固定效应”通常由关节对相邻肌腱的运动产生。斜支持带（交叉性动力性腱固定术），以及与腕关节屈伸对指外在肌腱的影响（直接腱固定效应），或与近端指间关节屈伸对指内在肌腱的影响（交叉性腱固定效应），都是解剖学上的例子。主要的腱固定术用于治疗指伸肌、指内在肌或拇外展长肌、拇短伸肌、拇长伸肌、拇短展肌麻痹的姑息性手术。
