手術(shù)后靠自身修復(fù)恢復(fù)率只有百分之二左右,不是傷口靠時(shí)間就能恢復(fù)的。因斷裂的臂叢神經(jīng)手術(shù)吻合只是為神經(jīng)恢復(fù)創(chuàng)造了條件,但不能恢復(fù)神經(jīng),其神經(jīng)吻合術(shù)后神經(jīng)吻合之處會(huì)形成新的神經(jīng)終板,神經(jīng)功能的恢復(fù)關(guān)鍵是神經(jīng)纖維和神經(jīng)細(xì)胞能不能再生穿過此神經(jīng)終板,如吻合后神經(jīng)不能興奮無力穿過此神經(jīng)終板既為手術(shù)失敗當(dāng)然也恢復(fù)無望。
