Dissection 10 Flashcards
Obstetric procedure
Pudendal nerve block
Supplies the skin over the posterior aspect of the thigh
Posterior cutaneous nerve of the thigh
Bony landmark on the skull
External occipital protruberance
Bony landmark on back of sacrum
Median sacral crest
What level are the iliac crests?
L3/L4
What level would you do a lumbar puncture and why?
L3/L4
-avoids injury to the terminal part of the spinal cord (conus medullaris)
What level does the spinal cord end?
L1/L2
Where does the iliotibial tract run to?
From ASIS to lateral tibail condyle at the Gerdy tubercle
What is the tensor fascia lata?
The muscular part of the fascia lata
Where does the gluteus maximus attach?
Proximally: iliac crest, sacrum, sacrotuberous ligament and coccyx
Distally: iliotibial tract
Most powerful extensor of the hip
Gluteus maximus
Muscle needed to get out of chair/climb up stairs
Gluteus maximus
Inferior gluteal neurovascular bundle
This bundle contains the inferior gluteal artery, vein and nerve (L5, S1 and S2)
What supplies the gluteus maximus?
Inferior gluteal neurovascular bundle
What supplies the gluteus medius and minimus?
Superior gluteal nerve bundle
What does the superior gluteal nerve bundle contain?
The superior gluteal artery, vein and nerve (L5, S1 and S2)
Where do the gluteus medius and minimus attach to?
Ilium to greater trochanter of femur
What do the gluteus medius and minimus do?
They abduct and internally rotate the thigh at the hip joint
Nerve supply to the gluteus medius and minimus?
Superior gluteal nerve (L5, S1 and S2)
How could you identify damage to the gluteus medius/minimus?
Trendelenberg test
What type of fibres are carried in the posterior cutaneous nerve of the thigh?
Sensory and sympathetic fibres
Supplies the skin and fascia of the posterior aspect of the thigh
Posterior cutaneous nerve
Pudendal nerve in relation to the posterior cutaneous nerve of the thigh?
Pudendal nerve is medial
Where must you give intragluteal injections and why?
Must be given to the upper outer (superolateral) quadrant of buttock to avoid injury to the sciatic nerve
