|
The head of the femur inserts into the
|
acetabulum
|
|
|
the hip bone (aka the ____) has 3 gluteal lines. what are they?
|
pelvic bone or ilium
anterior, inferior, posterior lines |
|
|
name the 4 iliac spines
|
anterior superior ASIS
Posterior Superior PSIS Anterior Inferior AIIS Posterior Inferior PIIS |
|
|
what bone do you sit on? what does it look like?
|
the ischium. looks like a curved hook "c-like". posterior
has a 3rd of the acetabulum included in it. |
|
|
3 parts of the pubis bone
|
superior and inferior ramus and obturator foramen
|
|
|
name the 2 important accessory ligaments from the sacrum to the ischium
|
sacrospinous ligament (divides the greater and lesser sciatic foramens)
sacrotuberous ligament |
|
|
abduction of thigh at hip joint is done by what muscle? what else does this muscle do?
|
gluteus medius-also prevents downward tilt of pelvis on opposite side
abduction of thigh also by the gluteus minimus (and prevention of downward tilt) |
|
|
trendelenburg's sign
|
dropped pelvis due to injury of gluteus medius and minimus on opposite side
|
|
|
what muscle crosses over both the hip joint and the knee joint? (laterally)
|
tensor fasciae latae-anything over 2 joints can cause problems clinically
|
|
|
5 muscles of the deep gluteal region superior to inferior
|
superior
(the deep gluteal region appears to form a super gem, in turn, obviously, to an inferior gem, which 4 females love) piriformis (appears to form) superior gemellus (a super gem) obturator internus (in turn, obviously) inferior gemellus (to an inferior gem) quadratus femoris (4 females) inferior |
|
|
Sacral Plexus Nerve
Name all 7 and their vertebrae origins |
L4,L5-S1-S4
superior glut 4,5,1 sciatic 4,5,1,2,3 inferior glut 5,1,2, N to obturator internus 5,1 N to quadratus femoris 5,1 Post. Femoral Cutaneous 1,2,3 Pudendal 2,3,4 |
|
|
arteries in the pelvis
|
abdominal aorta->common iliac->internal iliac (vs external) which divides into 1) superior gluteal artery and 2) inferior gluteal artery and internal pudendal
|
|
|
stuff exiting ABOVE piriformis muscle (in the greater sciatic foramen)
|
superior gluteal nerve (glut med, glut mini, TFL)
superior gluteal vessels |
|
|
stuff exiting BELOW piriformis muscle ( in greater sciatic foramen)
|
8 things (6 are nerves, 2 are vessels)
sciatic nerve inferior gluteal nerve (to glut maximus) inferior gluteal vessels N to Obturator Internus N to Quadratus Femoris post. femoral cutaneous N internal pudendal vessels Pudendal Nerve |
|
|
1 thing exiting the lesser sciatic foramen! what is it?
|
the obturator internus muscle
|
|
|
what structures enter the perineum? what do they pass thru?
|
3 things enter perimeum via passing thru the lesser sciatic foramen
PIN pudendal nerve Internal Pudendal vessels N. to obturator internus |
|
|
interomuscular injection should be given in which quadrant of the gluteal region? why is this?
|
in the superolateral part of upper lateral quadrant.
avoid injecting into or close to the sciatic nerve and other nerves and vessels located in the lower medial quadrant |
|
|
4 parts of the cruciate anastomosis
|
inferior gluteal artery
lateral circumflex femoral artery (transverse branch) medial circumflex femoral artery (transverse branch) first perforating artery |
|
|
piriformis syndrome is what? treatment?
|
the piriformis crosses 2 joints (sacroiliac and hip) with sciatic crossing underneath
sciatica=pain coursing down posterior leg following path of sciatic nerve treatment: biomechanical issue foot orthotics=limits rotation massage, stretching, ice usually due to result of stretching the piriformis muscle due to walking/running in laterally rotated way=tenses up piriformis |
|
|
SI Dysfunction (sacroiliac joint dysfunction)
causes? symptoms? treatments? |
excessive movement in the sacral/ilium joint causes osteoarthritis
pregnancy, additional weight, changes in gait stress the SI joints leg length discrepancies can cause this, along with hip, knee, ankle, foot pain symptoms=pain in lower back, back of hips, groin/thigh pain treatment: anti-inflammatory and PT |
