摘　　要：目的 阐明腕管内指浅屈肌4条肌腱的解剖学位置、排列方式和变异,以期丰富国人解剖学资料,为临床应用提供解剖学依据。方法 福尔马林溶液灌注固定的成人上肢标本88侧(左、右侧各44例),对其腕管内结构进行详细剖查,观察记录各结构的位置与排列,绘制模式图,统计分析各种结构排列关系。结果 腕管内指浅屈肌4条肌腱有6种排列方式。第1种:4条肌腱从小指到示指平行排列,约占14%;第2种:中指和无名指肌腱位于示指和小指肌腱上面,约占30%;第3种:中指和示指肌腱位于无名指和小指肌腱表面,约占2%;第4种:中指肌腱和正中神经位于其他手指肌腱的浅层,约占35%;第5种:示指、中指和无名指肌腱位于小指肌腱表面,约占4%;第6种为中指和小指肌腱位于示指和无名指肌腱之间,约占15%。指浅屈肌小指肌腱变异1例(2%)。结论 掌握腕管内指浅屈肌肌腱的解剖学知识,可以更好地理解第2~5指的各种运动,也有利于手外科医师的临床诊断和治疗。Objective To illuminate the topographical anatomy of the four flexor digitorum superficialis(FDS)tendons in carpal tunnel and its variation in Chinese Population.Methods Eighty-eight cases of formalin-fixed upper limbs of forty-four adult cadavers were investigated carefully.The carpal tunnels were dissected in detail,the position and arrangement relationship of each structure were observed and recorded,and illustrations were drawn.The proportion of various arrangement relationships was statistically analyzed.Results Six types of arrange-ments of four FDS tendons were found.The four FDS tendons arranged in parallel from little finger to index finger ac-counted for 14%.The middle and ring finger tendons located on the surface of index and little finger tendons account-ed for 30%.About 2%exhibited the middle and index finger tendons lying on the surface of ring and little finger ten-dons.About 35%were that middle finger tendon and median nerve located superficial to the other finger tendons.The index,middle and ring finger tendons superficial to little finger tendon was observed in 4%.The remaining 15%was that middle and little finger tendons lied between index and ring finger tendons.One case(2%)of tendon varia-tion of the little finger of superficial flexor digitorum.Conclusion Master the anatomical knowledge of the superfi-cial flexor tendon in the carpal tunnel,which can better understand the movement of the second to fifth fingers.And hand surgeons need to understand this anatomical knowledge for clinical diagnosis and treatment.
