summary for the Femoral Nerve of Lumber plexus

Femoral Nerve

  1. 1. Femoral Nerve <br />By: Huda Almubarak<br />
  2. 2. Lumber Plexus <br />Is formed insidePsaos Major with root value (L1, L2, L3, L4) <br />Femoral Nerve <br />Obturator Nerve <br />
  3. 3. Psaos Major<br />Origin: side of (T2-L5) vertebra and there’s discs. <br />Insertion: lassertrochanter of femur <br />
  4. 4. Psaos Major<br />Innervations: Anterior rami of lumber nerve (L1, L2, L3) <br />Action: Flexing + stabilizing hip joint<br />
  5. 5. Femoral nerve<br />- Arises from the lumbar plexus<br />- Descends within the groove between the psoasmajor and iliacusmuscles<br />- Lateral to the femoral artery as it enters the thigh<br />
  6. 6.
  7. 7. Femoral Nerve <br />Supply the frontal area of the thigh <br />Branch: <br />Anterior cutaneus branch. <br />Sapheneus nerve. <br />
  8. 8. Anterior cutaneus branch. <br />Sensation of the skin of the anterior and median aspect of the thigh <br />Injury: loss of sensation and sympathetic <br />
  9. 9. Sapheneus nerve<br />Sensation of the skin of patella and median side of the leg and foot <br />Injury: loss of sensation and sympathetic <br />
  10. 10. Sapheneus<br />
  11. 11. The Dermatome of the leg <br />
  12. 12. Femoral nerve injury <br />Paralysis: Quadriceps femoris muscle. <br />Deformity: Flexion of the knee<br />Sensation + Sympathetic: loss of sensation and sympathetic of skin of the anterior and median aspect of the thigh and the skin of patella and median side of the leg and foot <br />
  13. 13. Femoral nerve entrapments<br />Herniation of inter vertebral discs (L2/L3 or L3/L4)<br />At the level of inguinal ligament (femoral nerve neuropathy)<br />This may result in:<br />Weak extension of the knee<br />Weak patellar tendon reflex (L4 level reflex)<br />Cutaneous sensory changes (anterior thigh & L4 dermatome)<br />
