Investigation of compartmentalization on human flexor digitorum longus and their clinical significance
Objective To reveal morphologic features of human flexor digitorum longus (FDL) for clinical application. Methods Muscle architecture skill and modified Sihler's staining were used in this study. Results ①The FDL could be divided into tibial and fibula compartments by the instramuscular tendon; ②The 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 ①The FDL can be divided into tibial and fibula compartments, with independent nerve innervation; ②Two compartments formed by the half pinnate muscle, however, muscle strength of tibial compartment is more strong than that of fibula compartment.
