Using 16 cases of the human gluteus maximus from 8 cadavers, we examined macroscopically the arrangement and insertion of the muscle fibers. The muscle fibers of the gluteus maximus were devided into the superficial and deep groups. The iliotibial ligament also consisted of the superficial and deep layers. In all cases, the superficial fibers inserted into the superficial layer of the iliotibial ligament which attached to the lateral condyle of the tibia. The upper two thirds of the deep fibers (upper deep fibers) inserted into the deep layer of the iliotibial ligament which attached to the femur posterior-inferior to the greater trochanter. In 14 cases, lower one third of the deep fibers (lower deep fibers) inserted into the fascia lata covering the vastus lateralis. But in the other 2 cases, although most of the lower deep fibers inserted into the fascia lata, some inserted into the periostium covering the gluteal tuberosity. The present study demonstrated that the arrangement and insertion of the muscle fibers in the human gluteus maximus were much more complicated than as described in textbooks of anatomy. These results suggest that the gluteus maximus consists of two or more groups of muscle fibers which play different roles in the motion of the hip and knee joints.
