Close contact between extensor and flexor tendons to the bone structure of the wrist and distal radius shaft implies the possibility of alteration concerning the tendons' slide way and tensile direction in case of osteosynthesis in this region. Even a slightly damaged screw is mechanically capable of irritation and can be made responsible for a scrub-necrosis of an above tendon. The metal implant has to be selected in consideration of both the demands of the fracture and a free and natural tendons pathway. This is discussed by means of two implant-induced scrub necroses of the long pollex extensor and flexor tendon.
伸肌和屈肌腱与腕骨结构及桡骨远端骨干紧密相连，这意味着在此区域进行骨固定时，肌腱的滑动方式和拉伸方向有可能发生改变。即使是轻微损坏的螺钉在机械上也有刺激的能力，并可能导致上述肌腱的摩擦性坏死。金属植入物的选择必须兼顾骨折的需求以及肌腱自由自然的走行路径。本文通过两例因植入物导致的拇长伸肌腱和屈肌腱摩擦性坏死病例对此进行讨论。
