Iliopsoas
O:
• Psoas major: T12 vertebral body, L1-L5 vertebral
bodies, IVD and transverse processes
• Iliacus: iliac crest, iliac fossa, anterior SI ligaments
I: lesser trochanter
A: flex hip, *most likely externally rotates when hip is flexed
N:
• Psoas major: Femoral n/ L1-L3, (L4) anterior rami
• Iliacus: Femoral n
• V: iliolumbar a
Sartorius
O: ASIS
I: Proximal medial anterior tibial shaft (at
pes anserine)
A: Flexes , abducts, externally rotates hip.
Flexes knees. Contributes to medial rotation
of knee when flexed
N: Femoral n
V: profunda femoris a
Pectineus
O: superior ramus of pubis
I: pectineal line of femur- inferior to lesser
trochanter
A: adduct, flex thigh. Assist medial rotation
of thigh
N: Femoral n (2/3 of time) Obturator (1/3 of
time)… possible dual innervation • V: Medial femoral circumflex
P: Deep to femoral triangle. A great
opportunity to model and inform patient of
where you are palpating! • * sometimes included as part of medial
compartment
Rectus femoris
O: AIIS and superior acetabulum
I: tibial tuberosity (via patellar tendon and
The rectus femoris is the only quadriceps muscle to cross the hip and the knee
knee vs. Flexing extending hip Rectus femoris may attach at the superior acetabular labrum and could be implicated during some labral tears
patellar ligament)
A: flexes hip, extends knee
N: Femoral n
V: Lateral femoral circumflex a
P: Feel intermuscular septum separating rectus femoris from vastus lateralis and vastus
medialis. Feel muscle while flexing/extending
Intrinsic back, deep layer
Semispinalis capitis
Multifidi
Short rotators
Long rotators
Interspinalis
Intertransversarii
Vastus lateralis
O: greater trochanter, upper lateral lip of
linea aspera (on posterior femur)
I: Tibial tuberosity
A: extend knee
N: Femoral n
V: Lateral femoral circumflex
P: Deep to IT band. Feel in supine position
with leg hanging over table or in side-lying
position moving the knee into flexion and
extension
Vastus medialis
O: Intertrochanteric line, medial lip of linea
aspera
I: tibial tuberosity
A: extend knee
N: Femoral n
V: Femoral, profunda femoris, medial
superior genicular aa
P: Medial quad. Fibers run obliquely nearer
insertion
Vastus intermedius
O: proximal 2/3 of anterior and lateral shaft
of femur
I: tibial tuberosity
A: extend knee
N: Femoral n
V: Lateral femoral circumflex a
P: Deep to intermuscular septum of vastus
muscles and rectus femoris- begin deep
palpation by moving rectus femoris lateral
or medial and increasing pressure to feel VI
