摘　　要：目的为桡神经浅支切取后供区功能重建提供解剖学基础。方法成人前臂防腐标本30侧,测量桡神经浅支分支点与前臂外侧皮神经及正中神经尺侧缘的垂直距离;取6侧新鲜尸体与此水平分别将上述神经作病理切片,观察神经束数目。结果桡神经浅支浅段分支点到前臂外侧皮神经及正中神经尺侧的垂直距离分别为(6.0±1.5)mm及(35.7±2.8)mm。其在此平面附近桡神经浅支内有6～10个神经束;前臂外侧皮神经神经束数目为1～3束;正中神经神经束数目为19～27束。结论可通过端侧吻合的方式将桡神经浅支远断端与正中神经或前臂外侧皮神经吻合,以重建供区的感觉功能。Objective To provide anatomic basis after cutting superficial radial nerve to repair peripheral nerve defect and functional reconstruction of donor site.Methods 30 adult cadaveric upper limbs（15 left limbs and 15 right limbs） were fixed by formaldehyde.The vertical dimension from bifurcation of superficial radial nerve to lateral antebrachial cutaneous nerve and the vertical dimension to the median nerve were measured.The six fresh cadaveric upper limbs were made pathological section to count nerve-tract numbers of the same horizontal of cutaneous antebrachii lateralis nerve and median nerve under microscope.Results The vertical dimension from bifurcation of ramus superficial radial nerve to lateral antebrachial cutaneous nerve was（6.0±1.5）mm,and the vertical dimension to the median nerve was（35.7±2.8）mm.At the same horizontal,the nerve-tract counts of superficial radial nerve were 6～10;cutaneous antebrachii lateralis nerve was 1～3;median nerve was 19～27.Conclusion The sensory function of the donor by way of end-to-side anastomosis between far broken ends of superficial radial nerve and median nerve or lateral antebrachial cutaneous nerve can be reconstructed.
