1st MTP Pain? The Biomechanics of the Big Toe...

Remember the rockers? We have done a series on this in the past. Remember there are three: heel, ankle and forefoot. We are going to concentrate on the forefoot today.

As a reminder, forefoot rocker occurs at the 1st metatarsal phalangeal joint (big toe knuckle) as the tibia progresses over the forefoot during forward movement. You NEED 50 degrees to do this competently; you SHOULD have 65 degrees. When you don’t, you have a condition called hallux limitus. This could be from a number of reasons, from overpronation in the mid foot, to a bunion, to faulty firing patterns of the muscles which help to descend the 1st ray (the extensor hallucinations brevis, the peroneus longs and the short flexors off the toes). Pretty much, ANYTHING that causes a dorsal and posterior shift of the 1st MTP axis will cause limited forefoot rocker.

So, the question is, “Do you know where 1st 1st MTP pain may be coming from? How familiar are you with the mechanics of that joint?”

Take a few minutes to review it in this video with Dr Ivo Waerlop of The Gait Guys.
