Tibialis Posterior - of the deep posterior compartment of lower leg

We are still covering muscles of the "deep posterior compartment of the lower leg"
-deep meaning closest to the bone
-posterior meaning on the back of the leg

Tibialis Posterior is aka "Tom" of  Tom, Dick & Harry
,a group of 3 deep posterior lower leg muscles that share the same actions. These three
are often tight and need a good massage (especially runners!)

So deep that they live underneath the gastroc & soleus muscle (the more popular calf muscles we see) 'Tom' is also the largest of the three: 

Tibialis: refers to its attachment point on the Tibia (leg bone)
Posterior: on the back


ORIGIN:  the proximal 2/3 of the posterior tibia, fibula and interosseus membrane*

*a connective tissue that stretches between the tibia & fibula (lower leg bones)

INSERTION:   navicular, cuneiforms, cuboid, and bases of 2nd thru fourth metarsals

*you can see why we include your foot as part of a lower leg treatment - many clients come in with a lower leg injury but say that foot massage is not necessary, 

Let's take a closer look at those insertion points on the Bottom of the foot!


1- plantar flexion of the foot at the ankle joint:

2- inversion of the foot at the subtalar joint:

kinda similar eh? I think you can help but invert a lil' whilst you plantar flex ;)

Next week we'll cover ' DICK' of
Tom Dick & Harry

Tom = Tibialis Posterior
Dick = Flexor Digitorum Longus
Harry = Flexor Hallucis Longus

'gangs all here' 

....speaking of.... remember that 90s comedy  3rd rock from the sun?

ever notice that the 3 guys names are
Tom, Dick and Harry ?!?!
Because they're aliens and just trying to fit in...

like every other 'Tom Dick & Harry' ! 

Haha Harry was the weird one..
