When a foot over-pronates stress is unduly placed on the inside of the ankle and the knee, and over a long period of time, particularly if a person is involved in sports and running, this added stress starts to damage structures in the knee and ankle. The result is usually pain, particularly when running, which typically varies in severity. If the arch of the foot is weak, usually due to a lack of strength in supporting muscles of the foot, it can collapse over time, so people who aren?t flat footed can sometimes start to over-pronate in time. This can stress tissues on the underside of the foot, causing painful conditions like bunions (the abnormal inflammation and protrusion of the big toe?s joint) and Plantar Fasciitis (painful inflammation of connective tissues in the sole of the foot).
Over-pronation has different causes. Obesity, pregnancy, age or repetitive pounding on a hard surface can weaken the arch leading to over-pronation. Over-pronation is also very common with athletes, especially runners and most of them nowadays use orthotics inside their shoes. Over-pronation affects millions of people and contributes to a range of common complaints including sore, aching feet, ball of foot pain, heel Pain, achilles tendonitis, bunions, shin pain, tired, aching legs, knee pain and lower back pain. The most effective treatment solution for over-pronation is wearing an orthotic shoe insert. Orthotics correct over-pronation, thereby providing natural, lasting pain relief from many common biomechanical complaints.
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.
A quick way to see if you over-pronate is to look for these signs. While standing straight with bare feet on the floor, look so see if the inside of your arch or sole touches the floor. Take a look at your hiking or running shoes; look for wear on the inside of the sole. Wet your feet and walk on a surface that will show the foot mark. If you have a neutral foot you should see your heel connected to the ball of your foot by a mark roughly half of width of your sole. If you over-pronate you will see greater than half and up to the full width of your sole.
Non Surgical Treatment
Over-pronation and the problems that go with it are treated with shoe inserts called arch supports or orthotics. You can buy orthotics at a pharmacy or athletic shoe store or they can be custom made. Make sure the arch supports are firm. If you can easily bend them in half, they may be too flexible.
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.
