Very well observed Kay Warren. Misinformation like this can also cause faulty management. Probably they should have gotten another illustration for this. Netter illustrations are my favorite.

So, the plantar Fascitis is tearing the tendon away from the bone because it is so tight and the POD goes in and surgically snips the plantar fascitis so it no longer does that? Is this correct?

This illustration leaves a few things out. For instance:

#1 It makes the band look quite small and narrow, which is inaccurate. The attachment at the heel is about as wide as your thumb. At it's phalangeal end, it attaches to each toe. So it's 3-4 inches wide at that point.

#2 & #3 location of pain and growth of spur: It is VERY hard to damage a tendon. Tendons have very little in the way of pain receptor cells. The tendon is actually tearing AT THE BONE, and pulling off little bits of bone. It's called a "micro-avulsion fracture". How do we know this? Because bone only adds calcification (grows) when it's being damaged. A tendon that tears in the tendon itself will not cause bone growth, therefore you would have no spur. A tendon that tears at the bone itself will. Just ask a knee surgeon.

#4 incorrect placement of the attachment toward the toes. The plantar fascial band actually attaches to the phalanges, (the toes) NOT the metatarsals. This is a critical anatomical fact, and it has everything to do with the immense level of pull generated by the simple act of walking.

#5 Illustration completely leaves out the action of the toes. The pre-tensioning of the plantar fascial band by weight is rough, but it's not the whole story, by far. What really creates the huge level of pull it takes to pull tendon away from bone is the action of the toes. As you roll off your toes the tendons wrap around the ball of the foot cranking it down even tighter, and increasing the pull of the band at the heel. What, you don't believe me? Sit down, put one ankle on one knee. With the foot relaxed, press gently into the arch of the foot, feel it yield? Now with the other hand, take the toes, and pull them back, as if you were rolling off them, and press again into the arch. Feel the difference?
