伸指肌腱与屈指肌腱在手的功能上其重要性相同 [1 ] 。国内外对屈指肌腱血液供应的解剖研究较多 ,但对伸指肌腱血液供应的解剖研究的报道尚不多见。本文对 2 0例伸指肌腱的血液供应情况进行初步的解剖研究。1　材料与方法选用新鲜尸体上肢 2 0例 ,其中 17例经挠动脉灌注碳素墨 Extensorial tendon and flexor tendon in the hand function of the same importance [1]. There are many anatomical studies on the blood supply of flexor tendon at home and abroad, but the anatomic study on the blood supply of extensor finger tendon is still rare. This article 20 cases of extensor tendon blood supply preliminary anatomical study. 1 Materials and Methods 20 cases of fresh corpse upper limbs, of which 17 cases of infiltration of carbon ink by the flexible artery
