Abstract:
Vessels and nerves within the medial arm flap were studied in 40 upper limbsof adult cadavers.The chief results are as follows:1.The medial arm cutaneous arteries may arise from the superior ulnar colla-teral artery(45.3%?4.09),the brachial artery(25.0%?3.50),the deepbrachial artery(8.7%?2.32),the axillary artery(5.4?1.86%),or others(thesubscapular,the posterior circumflex humeral,the inferior ulnar collateral artery andmusculo-cutaneous arteries of the triceps,the biceps and the teres major).Thecaliber of its origin from the superior ulnar collateral artery is 1.73?0.06mm.Itaccompanies the ulnar nerve and the muscular branch of the radial nerve whichpasses to the medial head of the triceps.2.The medial arm cutaneous arteries may be divided into four types accordingto their number of sources:one-source type——10.0%?4.74;two-source type——52.5%?7.9;three-source type——32.5%?7.41;five-source type——5.0%?3.45.The chief cutaneous vein of the medial arm flap is the basilic vein and its tributa-ries.The caliber at the terminal end of the basilic vein is 4.76?0.25mm.3.The blood vessels within the medial arm flap anastomose into networks whichdrain from the whole flap.4.The diameter of upper part of the medial arm cutaneous nerve is 1.24mm.The diameter of upper part of the posterior arm cutaneous nerve is 0.5～1.0mm.The diameter of upper part of the medial forearm cutaneous nerve is 2.26mm.5.The blood vessels and the clinical applications of the medial arm flap werediscussed in this article.
