MUSCLES OF THE HIP JOINT
Name: Iliopsoas
MUSCLES OF THE HIP JOINT
The following muscles
cross ONLY the Hip joint
Origin:
- sides of lumbar vertebrae
- anterior sacrum
- inner ilium
Insertion:
lesser trochanter
Function:
flex hip
outward/lateral rotation of hip
(soccer)
Name: Pectineus
Origin:
Pubic crest
Insertion:
pectineal line of femur
Function:

outward rotation hip
'Deep Six' lateral rotators of the leg;
Gemellus Superior and Inferior,
Obturator Internus and Externus,
Quadratus Femoris,
Piriformis.
Origin:
sacrum
posterior ischium
obturator foramen
Insertion:
greater trochantor
Function:
outward rotation hip
tarsals
One of the Deep Six, the Piriformis muscle, is particularly important
because of its tendency to cause sciatica pain. Sciatica pain starts in
the lower back or the butt and often travels down the back or side of
the leg or around the hip depending on the individual situation.
Piriformis Syndrome is caused by pressure on the sciatic nerve where
it exits the pelvis through the sciatic notch. If the Piriformis is tight and
knotted then the nerve gets pinched between it and the hipbone. Often
people will have one leg or the other that they tend to hitch up on.
Some may sit for hours at a desk every day causing the entire pelvic
girdle to be tight. Often truck drivers will get Piriformis Syndrome
simply by driving long hours with a wallet in their hip pocket. By
keeping the Piriformis and the Deep Six loose you can reduce the
chance of lower back and sciatica pain and increase mobility.
