To palpate
Greater
Trochanter
• proximal lateral bony projection on the
femur- largest and strongest bone
• larger projection- at the junction of the
shaft and neck
• site of muscle attachment
• connected to lesser trochanter by the
intertrochanteric crest posteriorly and
intertrochanteric line anteriorly
• ITB, TFL
• gluteus medius, gluteaus
minus
• piriformis
• superior gemelli

gluteals and deep 6
Lesser
Trochanter
• bony projection a the proximal medial
femur- (posteromedial)
• smaller trochanter
• site of muscle attachment
• iliacus

• supine- hip into
flexion
Linea Aspera
• raised line on posterior femur
• has a medial and lateral lip
• starts about gluteal tuberosity and
ends at med/lateral supracondylar
lines
• vastus medials (medial lip)
• vastus iateralus (lateral)
• vastus intermedius (lateral)
• bicep femoris (short head)
• adductor longus
• adductor brevis
• adductor magnus (anterior
head)

and quads
• resist leg flexionhamstrings
Lateral Femoral
Condyle
• distal femur, site of muscle attachment
• superior supracondylar lines
• articulates w lateral meniscus
• lateral collateral ligament (w bursa)
• interior ACL and PCL
• medial articulates w patella, bursae,
retinacular fibers
• gastroc
• popliteus

• prone: plantar flexgastroc
• palpate lateral
condyle
Head of the
Fibula
• proximal end of fibula w tibia
• does not articulate with the femur
• not a weight bearing bone
• anterior/posterior/
interosseous ligament
• bicep femoris
• fibularis longus
• soleus
* supine: head of
fibula
* resist plantar flex/
eversion - fib long
* prone: plant flex w
knee bent for soleus
* or knee flex for
bicep femoris
Tibial Tuberosity
• bony projection on anterior proximal
tibia
• superior is tibial plato
• site of osgoode scholtters
• site which patellar ligaments attach
• patellar ligament
• rectus femoris
• vastus intermedius
• vastus lateralis
• vastus medialis
• patellar tendon & retinacular
fibers
• resist leg ext to
palate the quads
Interosseus
Membrane
• membrane spanning the length of the
tibia and fibula (in btw)
• holes for nerve and blood supply
• several muscles attach and pass
superficial to it
• tibialis anterior
• extensor digitorum longus
• fibularis tertius
• extensor hallucis longus
• tibialis posterior
• flexor hallucis longus
• supine: proximal to
distal end of tib/fib
• palate the anterior
compartment
Pes Anserine
Tendon
• goose foot

Muscles
To palpate
Navicular
• tarsal bone located on medial aspect
of the foot
• articulates with all 3 cuneiform
• talus posteriorly & cuboid laterally
• forms talo-calcaneo-navicular joint
(aka anterior subtalar joint)
• allows for inversion/eversion,
pronation/supination
• talo-navicular
• spring ligament
• bifurcate
• plantar/dorsal/
interosseous ligament
• tibialis posterior
• supine: find
navicular &
tuberosity
• prone: resist plantar
flexion/inversion to
tip post to pop up
Calcaneus
• short bone inferior to the talus
• heel bone, largest tarsal bone
• creates the subtalar joint w the talus
• inversion/eversion at this joint
• has shelf like projection that supports
part of the talus- sustentaculum tali
• calcaneal tuberosity touches the floor
• medial: deltoid
• lateral: ATFL, PTFL,
CFL
• lateral/medial/
interosseus/posterior
talo-calcaneal lig
• spring ligament
• bifurcate calcaneonavicular lig
• gastroc & soleus (achilles
tendon)
• plantaris
• quadratus plantea
• tibialis posterior
• extensor digitorum brevis
• extensor hallucis brevis
• abductor hallucis
• abductor digiti minimi pedis
• flexor digitorum brevis
• prone- activate:
gastroc/soleus
Cuboid
• articulates w calcaneus, navicular and
lateral cuneiform, 4/5th MT
• plantar/dorsal/
interosseous ligs
• flexor hallucis brevis
• tibialis posterior
Medial
Cuneiform
• most medial of 3 cuneiform bones
• articulates w 1st MT & navicular
• articulates with
intermediate
cuneiform, navicular,
1st MT
• tibialis anterior
• fibularis longus
• tibialis posterior
• supine: find
navicular then
cuneiform- can resist
tib ant
1st MT
• most lateral metatarsal- big toe
• articulates w medial cuneiform/
proximal phalanx of big toe
• base is free- has sesmoid bonesimpeded in the tendon
• tibialis anterior
• fibularis longus
• dorsal interossei
• supine: find
navicular/ come
anterior
• resist dorsi/inversion
for tib ant
5th MT
• most lateral metatarsal bone- pinkie
toe
• long bone
• articulates w the cuboid posteriorly &
5th phalanx
• fibularis tertius
• fibularis brevis
• flexor digiti minimi pedis
• dorsal interossei
• plantar interossei
• supine: come off of
the 5th MT drops
down
• resist dorsiflexion/
eversion for fib brev/
