Fifty upper extremities from fresh human cadavers age range 20 to 80 years were used in the study of the vascularization of the tendons of the digital extensor muscles. The blood supply to the tendon originates from different sources at different levels. At the level of the musculotendineal junction the tendon receives the blood supply through the arteries of the fleshy part of the muscle. In the synovial sheath the arteries reach the tendon through the mesotendon. In the metacarpal region and on the back of the digits the arteries reach the tendon through the paratenonium and through the branches of the digitopalmar arches. In all cases and at all levels the arterial branches to the extensors divide in a "T" shape manner into an ascending and a descending branch. Some areas of the tendon which are exposed to the less favourable mechanical conditions receive less blood supply.
在对指伸肌肌腱血管分布的研究中，使用了50条来自年龄在20至80岁之间新鲜人体尸体的上肢。肌腱的血液供应在不同水平源自不同来源。在肌腱-肌肉连接处，肌腱通过肌肉肉质部分的动脉接受血液供应。在滑膜鞘内，动脉通过腱系膜到达肌腱。在掌骨区域和手指背面，动脉通过腱旁组织和指掌侧动脉弓的分支到达肌腱。在所有情况和所有水平上，伸肌的动脉分支均以“T”形方式分为升支和降支。肌腱中一些承受不太有利机械条件的区域接受的血液供应较少。
