The tendon inserts on the greater trochanter of the proximal femur. The femur (thigh bone) has a pronounced anterior trochanter. The iliopsoas muscle joins to the femur at the lesser trochanter. The iliac subtendinous bursa lies between the lesser trochanter and the attachment of the iliopsoas. Each true leg has seven segments&colon; coxa, trochanter, femur, patella, tibia, metatarsus, and tarsus. Middle gluteal&colon; originates on the ilium and inserts on the greater trochanter. Ilipsoas&colon; originates on the ilium and inserts on the lesser trochanter. Distally the coxa bears an anterior and a posterior articulation with the trochanter. In parasitic Hymenoptera the base of the femur has the appearance of a second trochanter. Deep gluteal&colon; originates on the ischiatic spine and inserts on the greater trochanter. In Micropterigidae, the legs are three-segmented, as the coxa, trochanter, and femur are fused. A bursa is interposed between the tendon and the greater trochanter. These pierce the aponeurosis of the greater trochanter. A bursa is often found between the front of this muscle and the lesser trochanter. The minimus has similar functions and both muscles are inserted onto the greater trochanter.
