Summary Netter Plates: 330, 331, 375, 376, 382, 453, 454, 460, 461, 468, 469 Summary Rohen Plates: 329-331, 409-413, 430, 431, 432, 454, 455, 456, 457 The piriformis muscle is the reference for the identification of the vessels and nerves that pass through the greater sciatic foramen, superior and inferior to this muscle.
The fibers of this muscle pass lateral and downward and insert onto the sacrotuberous ligament and the glutealtuberosity of the femur.
Inferior gluteal nerve and vessels and Superior gluteal vessels-on the deep surface of the gluteus maximus The gluteus maximus muscle can be reflected laterally to its attachment on the femur.
Reflect the gluteus medius and examine the superior gluteal vessels and nerve.
Identify on the skeleton: posterior, anterior and inferior gluteal lines, greater and lesser sciatic notches, ischial tuberosity and spine; lesser and greater trochanters, glutealtuberosity, intertrochanteric crest, trochanteric fossa of femur; patella, and the head and neck of the fibula.
Identify the inferior gluteal nerve to the gluteus maximus.
Ischial tuberosities Bony prominences covered by the lower border of the gluteus maximus during extension of the hip (in standing), but is uncovered during flexion so that it bears the weight while in a sitting position.
Gluteal fold and sulcus Gluteal fold — formed by the inferior margin of the gluteus maximus muscle.
When the gluteus maximus is cut and reflected laterally, note the course of the sciatic nerve as it exits the infrapiriform foramen and passes midway between the ischial tuberosity and greater trochanter.
Predict the functional loss and cutaneous areas affected by a given nerve injury to the hip or posterior thigh region; or conversely, given a functional and/or cutaneous loss, be able to predict which nerve or nerves are involved and the probable level of the injury.
The superior gluteal artery originates from the posterior division of the internal iliac artery.
The superior gluteal nerve is from the sacral plexus (L4-S1).
1/4 of the muscle fibers attaches to the glutealtuberosity, between the greater trochanter and the linea aspera.
The gluteus maximus is innervated by the inferior gluteal nerve (L5, S1 and 2) and vascularized by inferior gluteal vessels along with neighboring vessels such as the superficial branch of the superior gluteal artery (Clemente plate 331; Grant p.
