Over pronation of the foot is commonly referred to as "flat feet." Many middle-aged men and women suffer from over pronation over time and as a result of wearing poor-fitting shoes, continuing with
repetitive exercising habits, or walking in high heels for long periods over several years. Regular speed-walkers often experience over pronation as well as a result of this activity.
Abnormal foot biomechanics usually causes over-use type injuries, occurring most frequently in runners. When a neutral foot pronates during walking or running, the lower leg, knee and thigh all
rotate internally (medially). When an athlete with an overpronated foot runs, this rotation movement is exaggerated and becomes more marked.
If you overpronate, your symptoms may include discomfort in the arch and sole of foot. Your foot may appear to turn outward at the ankle. Your shoes wear down faster on the medial (inner) side of
your shoes. Pain in ankle, shins, knees, or hips, especially when walking or running.Unfortunately, overpronation can lead to additional problems with your feet, ankles, and knees. Runners in
particular find that overpronation can lead to shin splints, tarsal tunnel syndrome, plantar fasciitis, compartment syndrome, achilles tendonitis, bunions (hallux valgus) patello femoral pain
syndrome, heel spurs, metatarsalgia. You do not have to be a runner or athlete to suffer from overpronation. Flat feet can be inherited, and many people suffer from pain on a day-to-day basis. Flat
feet can also be traumatic in nature and result from tendon damage over time. Wearing shoes that do not offer enough arch support can also contribute to overpronation.
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
Pronation and supination are bio-mechanical problems, and are best treated and prevented with orthotic inserts. But before you run out to buy orthotics it makes sense to get the right advice on
footwear, and the best advice I can give you, is to go and see a qualified podiatrist for a complete foot-strike and running gait analysis. They will be able to tell you if there are any concerns
regarding the way your running gait is functioning. After your running gait has been analysed, have your podiatrist, or competent sports footwear sales person recommend a number of shoes that suit
your requirements. Good quality footwear will go a long way in helping to prevent pronation and supination. And, if needed, invest in a pair of orthotic inserts to further prevent excessive pronation
The MBA implant is small titanium device that is inserted surgically into a small opening between the bones in the hind-mid foot: the talus (ankle bone) and the calcaneus (heel bone). The implant was
developed to help restore the arch by acting as a mechanical block that prevents the foot from rolling-in (pronation). In the medical literature, the success rate for relief of pain is about 65-70%.
Unfortunately, about 40% of people require surgical removal of the implant due to pain.
