摘　　要：目的探讨趾长屈肌的亚部划分,为临床外科"半肌"移位手术提供解剖学基础。方法大体解剖法、肌构筑法、改良Sihler’s染色法。结果①可依劈开趾长屈肌肌内腱板,把该肌分为胫侧和腓侧两个亚部;②胫侧亚部各构筑学值大于腓侧亚部;③两亚部存在单独神经支配。结论①趾长屈肌可分为胫侧亚部和腓侧亚部,两亚部有独立的神经支配;②趾长屈肌的两个亚部均为半羽肌,胫侧亚部产生的肌力大于腓侧亚部。Objective To reveal morphologic features of human flexor digitorum lougus （FDL） for clinical application. Methods Muscle architecture skill and modified Sihler＇s staining were used in this study. Results ① The FDL could be divided into tibial and fibula compartments by the instramuscular tendon; ② The values of muscle architecture of tibial compartment of FDL were bigger than those of the fibula compartment; ③Tibial compartment and fibula compartment were innervated respectively. Conclusions ① The FDL can be divided into tibial and fibula compartments, with independent nerve innervation; ② Two compartments formed by the half pinnate muscle, however, muscle strength of tibial compartment is more strong than that of fibula compartment.
