1
Q

borders of the gluteal region

A

sup - iliac crest

inf - gluteal fold/sulcus

laterally - greater trochanter of femur

2
Q

what lies between the buttocks

A

intergluteal cleft

3
Q

what muscle helps to define the gluteal fold

A

gluteus maximus and superficial fascia overlying it

4
Q

attachments of gluteus maximus

A

proximal: iliac crest, sacrum, sacrotuberus ligament and coccyx
distal: most fibres end up in the iliotibial tract, some fibres insert into gluteal tuberosity

5
Q

gluteus maximus function

A

extensor of the hip

6
Q

gluteus medius and minimus attachments

A

ilium and anterolateral aspect of the greater trochanter of the femur

7
Q

gluteus medius and minimus functions

A

abduct and medially rotate the thigh at the hip joint

8
Q

what spinal nerve roots form the inf and sup gluteal nerve

A

L5, S1 and S2

9
Q

where is the inferior gluteal neurovascular bundle in relation to the gluteus maximus

A

deep

10
Q

where is the superior gluteal neurovascular bundle in relation to gluteus muscles

A

deep to gluteus medius

11
Q

what is the function of the deep muscle layer

A

laterally rotate the lower limb at hip joint

12
Q

describe the iliotibial tract

A

runs from ASIS to anterolateral (Gerdy) tubercule of tibia

the tensor fascia lata is enclosed within the proximal portion of the tract

13
Q

where does the sciatic nerve emerge in the gluteal region

A

inferior to periformis

14
Q

what happens when the sciatic nerve roots are affected by slipped discs

A

symptoms in foot - sciatica

15
Q

what 3 nerves are found in the gluteal region

A

pudendal,s ciatic and PCNT

16
Q

what foramen do the sciatic nerve and PCNT pass through

A

greater sciatic foramen

17
Q

lumbar puncture

A

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

18
Q

describe the lumbar puncture method

A

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

19
Q

why does insertion occur at L3/4 level

A

in adults spinal cord finishes at L1/2 vertebrae

this avoids injury to the terminal part of the spinal cord - conus medullaris
