The human foot is comprised of 26 bones and 33 joints-one fourth of all the bones in your body are in your two feet. Your feet have two functions that must be performed with every step; landing slightly on the lateral side of your heel and then proceeding along the lateral side of the foot to the fifth toe and then rolling in toward the great toe the arch gently collapses and the foot elongates slightly and absorbs the shock of 1 1/2 times what you weigh coming down on it. If this was not accomplished and the arch did not absorb the shock, the cartilage in your ankle, knee, hip and lower back would degenerate at a very early age. Then within a split second the foot must gently rock back slightly to the lateral side, become very rigid,-requiring all 33 joints to be aligned properly-and propulse against the forces of gravity-with a force equal to 1 1/2 times what you weigh to lift you off the ground and take a step. All of this occurs between 8,000 & 10,000 times a day- without you giving much thought to it- unless your foot or ankle hurts.
Most of the common foot complaints; heel spur/plantar fasciitis, bunions, hammer toes, neuromas, flatfoot, high arch, weak ankles, can all be traced to how well the 26 bones you inherited in each foot performed these two very totally different functions with each step and within a split second. Genetics will play a tremendous role in determining whether your foot bones function together as a unit very well, which means you may never come to the foot Doctor, or not very well, and soft tissue problems and joint pain will have you coming to the foot Doctor.
With this in mind, it is extremely important that your foot specialist appreciate the biomechanical alignment of your feet and address the pathological biomechanics to not only eliminate your symptoms of pain, but also to address the most serious underlying cause of the pain. This is a basic fundamental tenet of my practice.
