  1. Congenital hip Dislocation (dysplasia)
    • Shallow acetabulum causes femoral head to slide upward. Joint capsule remains intact but stretched
    • 80% of pts are female
    • usually found as infants.
    • easily treatable in newborns, if left untreated, hip will continue to deterioate
    • can lead to OA
    • possibly caused by the increase in hormone during pregnancy, can pass over placenta to baby
  2. Legg-Calve-Perthes (Coxa Plans)
    • Common in boys age 4-10
    • interruption of the blood supply to the femoral head causing it to deteriorate and die
    • within months the blood supply will return and create cells which can begin to rebuild the bone over 2-4 yrs
    • Pt will present with loss of hip motion and limp
  3. Symptoms of Legg-Calve Perthes (Coxa Plana)
    • Knee pain
    • limited hip ROM
    • limp
  4. Angle of Torsion
    • Angle between shaft and neck of femur
    • Normally head and neck rotated outward 15-25 degrees from shaft
  5. Increase Angle of Torsion
  6. Decrease Angle of Torsion
  7. ITBand Syndrome
    • overuse injury that caused lat knee pain
    • repeated friction of the band that slides over that lat femoral epicondyle during knee motion
  8. ITBand syndrome is commonly seen in
    • runners
    • bicyclists
  9. Angle of Inclination
    • Angle between shaft and neck of femur
    • Normally 125 degrees
  10. Coxa Valga
    • neck shaft angle greater than 125
    • tends to make the limb longer, placing hip in adducted position during WB
  11. Coxa Vara
    • Neck shaft angle less than 125
    • makes limb shorter leading to pelvic drop on WB side
  12. Hip Pointer
    • Occurs at pelvis
    • Severe bruise caused by direct trauma to iliac crest of the pelvis
  13. Causes of hip pointer
    • bleeding into abdominal muscles
    • Pain- when walking, laughing, coughing, breathing deeply
