  1. Clinical Anatomy of the Hip Will Collett Peer Support 2014

  2. Objectives • Avascular necrosis • Superior Gluteal Nerve Injury • Inferior Gluteal Nerve Injury • Thomas Test • Injection Site

  3. Avascular Necrois • What makes the femoral head susceptible to AVN? • Medial and lateral circumflex arteries and ligamentumteres artery • Intracapsular Vs Extracapsular • How can we injure the hip causing AVN? • # NOF • Car crash • What are the signs and symptoms of AVN? • # NOF – shortened and externally rotated • Pain, reduced movement, Weight bearing Diagnosis?

  4. Avascular necrosis

  5. Intracapsular Extracapsular

  6. Superior Gluteal Nerve Injury • Innervates? • Lost ability to? • Abduct the hip • Trendelenburg gait or sign? Gluteus Medius & Minimus (L4-L5) Superior gluteal nerve (L4-L5)

  7. SIGN

  8. GAIT

  9. Inferior Gluteal Nerve Gluteus Maximus (L5-S1) • Innervates? • Lost ability to? • Prevent trunk tipping forwards during gait • Extend the hip • Gait? • lurching backward when the weaker limb is on the floor during walking (heel strike) • Buttock wasting • Hamstring Compensation

  10. Thomas Test

  11. Intramuscular Injection • Method 2 • - Vertical line through highest point of crest • - Line from PSIS to the greater trochanter • Method 1 • - Vertical line through highest point of iliac crest • - Horizontal line midway between ischial tuberosity and highest point of iliac crest
