Anatomy: Gluteal Region Flashcards
borders of the gluteal region
sup - iliac crest
inf - gluteal fold/sulcus
laterally - greater trochanter of femur
what lies between the buttocks
intergluteal cleft
what muscle helps to define the gluteal fold
gluteus maximus and superficial fascia overlying it
attachments of gluteus maximus
proximal: iliac crest, sacrum, sacrotuberus ligament and coccyx
distal: most fibres end up in the iliotibial tract, some fibres insert into gluteal tuberosity
gluteus maximus function
extensor of the hip
gluteus medius and minimus attachments
ilium and anterolateral aspect of the greater trochanter of the femur
gluteus medius and minimus functions
abduct and medially rotate the thigh at the hip joint
what spinal nerve roots form the inf and sup gluteal nerve
L5, S1 and S2
where is the inferior gluteal neurovascular bundle in relation to the gluteus maximus
deep
where is the superior gluteal neurovascular bundle in relation to gluteus muscles
deep to gluteus medius
what is the function of the deep muscle layer
laterally rotate the lower limb at hip joint
describe the iliotibial tract
runs from ASIS to anterolateral (Gerdy) tubercule of tibia
the tensor fascia lata is enclosed within the proximal portion of the tract
where does the sciatic nerve emerge in the gluteal region
inferior to periformis
what happens when the sciatic nerve roots are affected by slipped discs
symptoms in foot - sciatica
what 3 nerves are found in the gluteal region
pudendal,s ciatic and PCNT
what foramen do the sciatic nerve and PCNT pass through
greater sciatic foramen
lumbar puncture
used to look for evidence of conditions affecring the brain, spinal cod of nervous system
pressure measurements and CSF samples taken from subarachnoid space surrounding the spinal cord
describe the lumbar puncture method
patient on L side and fully flexed (knees to chin)
iliac crests identified (plane L3/4)
spinal pack used to withdraw CSF at this level
why does insertion occur at L3/4 level
in adults spinal cord finishes at L1/2 vertebrae
this avoids injury to the terminal part of the spinal cord - conus medullaris
