肘关节动脉的应用解剖

APPLIED ANATOMY OF ARTERIES OF ELBOW JOINT

成人上肢标本30例,动脉灌注红色乳胶和常规固定后,解剖、观察和测量。肘关节囊动脉供应,后壁优于前壁,动脉支在囊前壁和后上壁内多纵行,其余部分多横行。肱骨下端骨外动脉均来源于肘区动脉网;外侧髁的后外侧面血供最丰富;在滑车内侧面常有呈半环形行走的滑车内侧唇动脉。尺骨上端主要由尺侧和骨间返动脉分支供应。分布于桡骨上端的动脉支,形成紧贴骨面上行的颈升动脉,该动脉分支稀疏,吻合不良。根据观测结果,讨论了肘关节动脉分布的临床应用要点。

30 adult fresh upper limb specimens injected arterily with red emulsin were dissected, observed and measured under the operating microscope. The blood supply of the anterior wall of the joint capsule is more dominanter than the posterior wall. Arteries is longitudinal in the anterior and postersuperior walls of the elbow joint capsule and is transversal in the other parts of capsule. The arteries of the lower end of humerus all originate from the elbow asterial network; the blood supply of the posterlateral part of the lateral condyle is the richest and there is a semicircular trochlea medial labium artery in the medial surface of trochlea. The bone arteries outside of the upper end of ulna mainly derived from the branches of the ulnar recurrent artery and the cervical ascending artery, which ascends near the bone and distributes sparsely and anatomoses badly, is the only outside bone artery of the upper end of the radius. Based on the results, the clinical value of the main applied points of the elbow joint arterres were discussed.
