Pronation is the natural act of the body spreading the impact of walking, jogging or running throughout the foot evenly. As the foot strikes the ground, the ankle naturally rolls inward absorbing the
shock of the ground and mobilizing to the terrain. Overpronation is when the ankle of the foot rolls in past its normal 15? of inward rotation. The cause of this could be many things such as foot
type, biomechanics, or compensation strategies. People with flat feet often, although not always, overpronate.
Over-pronation occurs when the foot collapses too far inward stressing the plantar fascia (the area underneath the arch of the foot.) Normally, one pronates every time he or she walks, but excessive
pronation is called over-pronation. When this occurs it can cause pain in the feet, knees, hips, low back and even the shoulder. Decreasing over-pronation, which is very prominent in runners, will
help add endurance, speed and efficiency to your run and ultimately place less stress on your body.
Eventually, over-pronation can lead to a full list of maladies including flat feet, plantar fasciitis, plantar fibroma, neuromas, heel spurs, shin splints, ankle sprains, bunions, hammertoes,
calluses, and pain in the arches, knee, hip and lower back. But it doesn?t have to go that far, because there are steps we can take to correct the over-pronation. In the vast majority of cases, we?ll
prescribe custom foot orthotics, which will realign your ankles, redistribute the weight, support the arch and reduce the twisting. Many orthotics will fit snugly into your normal shoes. Although
we?ll also take a look at the type of shoes you wear to see if they are contributing to the problem.
Look at the wear on your shoes and especially running trainers; if you overpronate it's likely the inside of your shoe will be worn down (or seem crushed if they're soft shoes) from the extra
Non Surgical Treatment
Over-Pronation can be treated conservatively (non-surgical treatments) with over-the-counter orthotics. These orthotics should be designed with appropriate arch support and medial rearfoot posting to
prevent the over-pronation. Footwear should also be examined to ensure there is a proper fit. Footwear with a firm heel counter is often recommended for extra support and stability. Improper fitting
footwear can lead to additional problems of the foot.
Calcaneal "Slide" (Sliding Calcaneal Osteotomy) A wedge is cut into the heel bone (calcaneus) and a fixation device (screws, plate) is used to hold the bone in its new position. This is an aggressive
option with a prolonged period of non-weightbearing, long recovery times and many potential complications. However, it can and has provided for successful patient outcomes.
