Osteo nd Gluteal Flashcards
what makes the hip bone
ilium, ischium, pubis
what is the acetabulum
meeting point of 3 bones - y shaped
the hip bones are equivalent of what in the UE
clavicle and scapula
articulation of hip bones
post - sacroiliac joint
ant - symphysis pubis
what level is the iliac crest
L4
parts of iliac crest
ASIS - PSIS
iliac tubercle 2 in. behind ASIS
at what level is anesthesia given
L4 - bc if above L1 it will cause paralysis
sit bone
ischial tuberosity
attachment for hamstring musckes
ischial tuberosity
significance of ischial spine
lig attachement - measurement of pelvic oppening - pointed = too narrow for delivery
greater and lesser sciatic notches are converted into greater and lesser sciatic foramina by the presence of
sacrospinous and sacrotuberous ligaments
articulation of superior ramus of symphysis pubis
illium and ischium
articulation of inferior ramus of symphysis pubis
ischial ramus - below obtu for
what is pubic crest
upper border of body of pubis; lat - pubic tubercle
acetabulum contributions
ischium
ilium
pubis
what shape is acetabulum
horseshoe
significance of acetabular notch
passage of nerves nd bv to hip
articulation of sacrum
sacroiliac - plane - glide
what is sacral promontory
S1 - becomes posterior margin of pelvic inlet
what is sacral hiatus
S4/5 fail to meet at midlind
what is fovea capitis
– small depression at the center of the head for attachment of ligamentum teres; contains blood supply to the head of femur coming from obturator artery
normal angle if incline
125 deg
coxa vara vs valga
vara - less than 120
valga - above 135
significance of intertrochanteric line
attachment of iliofemoral lig - separates greater nd lesser trochanter
medial supracondylar ridge
adductor tibercle
attachment off gluteus maximus
gluteal tuberosity
separates lateral and medial condyles
intercondylar notch
largest sesamoid bone
patella
large wight bearing bone of leg
tibia
largest bone of the foot
calcaneum
boundaries of glutes
sup - iliac crest
inf - gluteal fold of the buttock
sensory supp of buttocks
UM - Posterior rami of first 3 lumbar and first 3 sacral n.
LM - Posterior cutaneous n. of thigh ( S1-3)
UL - Lateral branch of iliohypogastric (L1 and T12 – anterior rami)
LL - Lateral cutaneous n. of thigh (L2 & L3)
what supplies the coccyx and cleft
Small branches of sacral and coccygeal nerves
compare the fascia in glutes
Superficial fascia
Thick Large quantity of fat Responsible for prominence of buttock
Deep fascia
Continuous with deep fascia of thigh or fascia lata
Splits to enclose the gluteus maximus
On lateral surface it thickens to form a strong wide band, iliotibial tract (from tubercle of iliac crest to the lateral condyle of tibia)
Iliotibial tract forms the sheath for tensor fasciae latae muscle
what are the branches of lumbrar plexus
Branches:
- L1 – iliohypogastric, ilioinguinal
- L1-2 – genitofemoral
- L2 – 3 – Lateral femoral cutaneous
- L2,3,4 – Obturator nerve
- L2,3,4 – Femoral nerve
branches of lumbosacral plexus
Branches:
*Sciatic nerve (L4-S3)
*Superior gluteal n. (L4-S1)
*Inferior gluteal n.(L5-S2)
*N. to quadratus femoris (L4-S1)
*N. to obturator internus (L5-S2)
*Posterior cutaneous n. of thigh (S1-3)
*Pudendal n. (S2,3,4)
*N. to piriformis (S1-2)
what type of joint is the hip joint
Multiaxial Ball and socket joint
describe the iliofemoral lig
Y lig of bigelow - prevents hyper ex nd lat rot - strongest
describe the pubofemoral lig
triangular - limits ext nd abd
ischiofemoral lig
spiral - limits ext
ligamentum teres
flat and triangular - limits add - pathway for bv to enter head of femur
transverse acetabular lig
bridges acetabular - tunnel where bv nd nerves enter hip joint
muscles for hip flexion
Iliopsoas (strongest flexor), sartorius, rectus femoris, pectineus, adductor longus, adductor brevis, adductor magnus and gracilis
muscles for hip extension
hamstring, adductor magnus, gluteus maximus
muscles for hip abduction
gluteus medius and minimus, assisted by sartorius, tensor fasciae latae and piriformis
muscles for hip adduction
adductor longus, brevis, magnus, assisted by gracilis & pectineus
medial rotation of hip
g. medius and minimus, tensor fascia lata
lat rotation of hips
obturator externus & internus, gemelli, piriformis, quadratus femoris and is assisted by g. maximus
what type of joint is sacroiliac joint
plane
fucntion of sacroiliac joint
shock absorber for the spine above and
converts torque from the lower extremities into the rest of the body
ligs of sacroiliac joint
Anterior sacroiliac Ligament Posterior sacroiliac Ligament Interosseous ligament Sacrospinous and sacroiliac ligament
what nerve passes sacroiliac joint
superior gluteal
what is the func of sacrococcygeal joint
Forward and backward movement
ligs of sacrococcygeal
Anterior Sacrococcygeal Ligament
Posterior Sacrococcygeal Ligament
Lateral Sacrococcygeal Ligament
Interarticular Ligaments wo bones
nerve of sacrococcygeal
pudendal
what are the cartiligenous jints of the hu=ip
sacrococcygeal
symphysis pubis
ligs of symphysis pubis
Anterior pubic ligament Posterior pubic ligament Superior pubic ligament Arcuate pubic ligament
nerve of symphysis pubis
branches from the iliohypogastric, ilioinguinal and pudendal nerves.
what are the movements of symhysis pubis during birth
angulation, rotation and displacement
+ trendelenburgs is weakness of
gluteus medius nd minimus
