    1. 1. Chapter 21: The Thigh, Hip,Groin, and Pelvis
    2. 2. Anatomy of the Thigh
    3. 5. Nerve and Blood Supply <ul><li>Tibial and common peroneal are given rise from the sacral plexus which form the largest nerve in the body the sciatic nerve complex </li></ul><ul><li>The main arteries of the thigh are the deep circumflex femoral, deep femoral, and femoral artery </li></ul><ul><li>The two main veins are the superficial great saphenous and the femoral vein </li></ul>
    4. 6. Fascia <ul><li>The fascia lata femoris is part of the deep fascia that invests the thigh musculature </li></ul><ul><li>Thick anteriorly, laterally and posteriorly but thin on the medial side </li></ul><ul><li>Iliotibial track (IT-band) is located laterally serving as the attachment for the tensor fascia lata and greater aspect of the gluteus maximum </li></ul>
    5. 7. Functional Anatomy of the Thigh <ul><li>Quadriceps insert in a common tendon to the proximal patella </li></ul><ul><li>Rectus femoris is the only quad muscle that crosses the hip </li></ul><ul><ul><li>Extends knee and flexes the hip </li></ul></ul><ul><li>Important to distinguish between hip flexors relative to injury for both treatment and rehab programs </li></ul>
    6. 8. <ul><li>Hamstrings cross the knee joint posteriorly and all except the short of head of the biceps crosses the hip </li></ul><ul><li>Bi-articulate muscles produce forces dependent upon position of both knee and hip joints </li></ul><ul><li>Position of the knee and hip during movement and method of injury (MOI) play important roles and provide information to utilize w/ rehab and prevention of hamstring injuries </li></ul>
