第四趾主要动脉与神经断层的解剖观测

Observation of blood vessels and nervers on sections of the fourth toe

目的为断趾再植及断层解剖学提供断层参考资料。方法用30例成人第四趾(男16例、女14例),经组织学处理切片,在显微镜下观测。结果趾跖腓侧固有动脉和神经纵径和横径的平均值分别大于0.43 mm和0.65 mm,趾跖胫侧固有动脉和神经纵径和横径的平均值分别为0.55 mm和0.58 mm。结论神经与同名动脉基本上位于同一区内伴行。

Objective To provide anatomical data of the fourth toe sectional area for sectional anatomy and replantation of severed toes.Methods The fourth toes were sectioned by histological method and observed under microscope.Results The fibular proper plantar arteries and nerves longitudinal and transversal sectional average diameters were longer then 0.43mm and 0.65mm respectively.Those of the tibial proper plantar arteries and nerves longitudinal and transversal sectional average diameters were 0.55mm and 0.58mm respectively.Conclusion The arteries and nerves with same name are in the same area.
