【摘要】：一、研究的目的及意義 臂叢神經(jīng)根性撕脫傷一直是創(chuàng)傷骨科臨床的難題，尤其全臂叢或下臂叢根性撕脫傷，，目前尚無(wú)行之有效的修復(fù)方法以恢復(fù)有用的手內(nèi)肌功能。借鑒吻合血管、神經(jīng)的(?)、趾短伸肌皮瓣移植重建嚴(yán)重火器性手部損傷后拇對(duì)掌及內(nèi)收功能的成功經(jīng)驗(yàn)，應(yīng)用吻合血管、神經(jīng)的(?)、趾短伸肌移植重建臂叢根性撕脫傷，尤其是陳舊性損傷手內(nèi)在肌功能可能是一種有效的治療方法。但由于臂叢根性撕脫傷的特殊性，在手腕部受區(qū)缺乏可供直接縫接的運(yùn)動(dòng)性移位神經(jīng)支，而可供縫接的運(yùn)動(dòng)性移位神經(jīng)支的平面在上臂部或肘部(如下臂叢根性撕脫傷)。因此，研究(?)、趾短伸肌的運(yùn)動(dòng)神經(jīng)支在腓深神經(jīng)中的定位及其可逆行分離的最大長(zhǎng)度等相關(guān)解剖學(xué)基礎(chǔ)，有助于確立行選擇性運(yùn)動(dòng)性神經(jīng)支(束)移位直接縫接或經(jīng)神經(jīng)移植縫接(?)、趾短伸肌的運(yùn)動(dòng)神經(jīng)支，這也是(?)、趾短伸肌移植重建臂叢根性撕脫傷后手內(nèi)在肌功能這一新術(shù)式能否取得良好療效的關(guān)鍵。 二、材料和方法 1、顯微解剖研究： 采用完整的中國(guó)成人尸體進(jìn)行研究(由南方醫(yī)科大學(xué)解剖學(xué)研究所提供)，尸體經(jīng)甲醛防腐固定、紅色乳膠動(dòng)脈灌注。共采用尸體下肢標(biāo)本30側(cè)，其中男性20側(cè)，女性10側(cè)。于(?)、趾短伸肌起止點(diǎn)對(duì)其進(jìn)行完整解剖，進(jìn)行神經(jīng)血管修潔，充分清除肌表面的脂肪和筋膜，對(duì)(?)、趾短伸肌的大體形態(tài)——長(zhǎng)度、厚度及寬
[Abstract]:The purpose and significance of the researchBrachial plexus root avulsion is always a difficult problem in orthopedic trauma, especially in total brachial plexus or lower brachial plexus root avulsion.The successful experience of reconstruction of thumb palmar and adductive function after severe firearm injury was studied by using vascular anastomosis, nerve anastomosis and transplantation of extensor digitorum brevis musculocutaneous flap for reconstruction of brachial plexus root avulsion injury by anastomosis of blood vessels and nerve, transplantation of extensor digitorum brevis muscle to reconstruct root avulsion of brachial plexus.In particular, old injury of the intrinsic muscle function of the hand may be an effective treatment.However, because of the particularity of brachial plexus root avulsion, there is a lack of motor transposition nerve branch in the recipient region of wrist, and the plane of motor transposition nerve branch can be sutured in upper brachial part or elbow (as follows, brachial plexus root avulsion injury.Therefore, the location of motor nerve branch of extensor digitorum brevis in the deep peroneal nerve and the maximum length of retrograde separation were studied.It is helpful to establish the motor nerve branch of the extensor digitorum brevis muscle by selective transposition of motor nerve branch (bundle) or through nerve graft suture.This is also the key to the success of the new method of reconstruction of the intrinsic muscle function of the hand after brachial plexus root avulsion injury by the transplantation of extensor digitorum brevis.II. Materials and methods1. Microanatomical study:The complete cadavers of Chinese adults were studied (provided by the Institute of Anatomy, Southern Medical University). The cadavers were fixed with formaldehyde and infused with red latex artery.A total of 30 cadaveric lower extremities were collected, including 20 males and 10 females.At the beginning and ending point of extensor digitorum brevis, complete dissection was carried out, nerve and blood vessels were cleaned up, fat and fascia on muscle surface were removed fully, and the gross morphology, length, thickness and width of extensor digitorum brevis were studied.
