    Study Notes

    Gluteal Region Anatomy

    • The gluteal region encompasses the posterior aspect of the pelvis, crucial for movement and stability.
    • Includes major muscles: gluteus maximus, medius, minimus, and others aiding hip extension and abduction.

    Iliac Crest

    • The superior border of the ilium part of the pelvis; important for muscle attachment and landmark for injections.

    Gluteal Fold

    • The crease formed between the buttocks and thigh; significant in anatomical positioning and aesthetics.

    Greater Sciatic Foramen

    • Opening for nerves and vessels, including the sciatic nerve; crucial for lower limb innervation.

    Lesser Sciatic Foramen

    • Smaller opening below the greater sciatic foramen; allows passage for the obturator internus tendon.

    Iliolumbar Ligament

    • Connects the ilium to the lumbar vertebrae, providing stability to the lumbosacral junction.

    Iliofemoral Ligament

    • Strong ligament of the hip joint that prevents hyperextension; shaped like an inverted "Y".

    Ischiofemoral Ligament

    • A ligament supporting the hip joint, located posteriorly; helps stabilize the hip during movement.

    Sacrotuberous Ligament

    • Connects the sacrum to the ischial tuberosity; provides stability to the sacroiliac joint.

    Sacrospinous Ligament

    • Attaches the sacrum to the ischial spine; plays a role in pelvic stability.

    Posterior Sacroiliac Ligament

    • Connects the posterior surfaces of the sacrum and ilium; aids in sacroiliac joint stability.

    Gluteus Maximus

    • The largest gluteal muscle, primarily responsible for hip extension and lateral rotation.

    Trochanteric Bursa

    • Bursa located near the greater trochanter of the femur; reduces friction between the gluteus maximus and the femur.

    Gluteofemoral Bursa

    • Positioned between the gluteus maximus and the femur; assists in reducing friction during hip movement.

    Ischial Bursa

    • Located over the ischial tuberosity; cushions the area against pressure during sitting.

    Gluteus Medius

    • Positioned laterally on the pelvis; crucial for hip abduction and stabilization during walking.

    Gluteus Minimus

    • A smaller muscle located beneath the gluteus medius; assists in hip abduction and internal rotation.

    Piriformis

    • A deep muscle in the gluteal region, involved in lateral rotation of the hip; can affect sciatic nerve pathways.

    Obturator Internus

    • A muscle aiding hip lateral rotation; located deep within the gluteal region.

    Obturator Externus

    • A muscle that assists in lateral rotation of the hip and is located externally to the obturator internus.

    Gemellus Superior

    • A small muscle located above the obturator internus; aids in lateral rotation of the hip.

    Quadratus Femoris

    • A flat, quadrilateral-shaped muscle involved in lateral rotation of the hip joint.

    Suprapiriformis Hiatus

    • Opening above the piriformis muscle; allows passage for the superior gluteal nerve and vessels.

    Infrapiriformis Hiatus

    • Opening below the piriformis; permits passage for the inferior gluteal nerve and sciatic nerve.

    Superior Gluteal Nerve

    • Nerve responsible for innervating the gluteus medius, minimus, and tensor fascia latae.

    Inferior Gluteal Nerve

    • Innervates the gluteus maximus muscle; essential for hip extension and stabilization.

    Safe Area for Intragluteal Injection

    • Identified as the upper outer quadrant of the gluteal region to avoid sciatic nerve damage.

    Iliotibial Tract

    • A thick band of connective tissue along the outside of the thigh; stabilizes the knee during activities.

    Tensor Fascia Latae

    • A muscle located at the lateral side of the hip; aids in hip flexion and abduction, contributing to the stability of the knee through the iliotibial tract.
