Pes planus is the medical term for flat feet. It comes from Latin, Pes = foot and Planus = plain, level ground. Very few people suffer from this condition, as a true flat foot is very rare. Less than 5% of the population has flat feet. The majority of the population, however, has fallen arches (an estimated 60-70% of the population) known in the medical profession as ?excess pronation? or over-pronation. Over-pronation means the foot and ankle tend to roll inwards and the arch collapses with weight-bearing. This is a quite a destructive position for the foot to function in and may cause a wide variety of foot, leg and lower back conditions.
Although there are many factors that can contribute to the development of these conditions, improper biomechanics of the body plays a large and detrimental role in the process. Of the many biomechanical elements involved, foot and ankle function perhaps contribute the most to these aches and pains.
Overpronation can negatively affect overall body alignment. The lowering of the longitudinal arch pulls the heel bone in, causing the leg, thigh bone and hip to rotate inwards, and an anterior tilt of the pelvis. Unnecessary strain to the ankles, knees, hips and back can result. Plantar fasciitis and inflammation, metatarsal pain, problems with the Achilles tendon, pain on the inside of the knee, and bursitis in the hip are just some of the conditions commonly associated with pronation.
Bunions, calluses and crooked toes may indicate alignment problems. So, it is important to ascertain the condition of a client's toes. Check the big toe to determine if the first joint of the toe is swollen, has a callus or bunion, and/or looks as though it abducts (i.e., hallux valgus) rather than pointing straight ahead. Also, look to see if the lesser toes seem to "curl up" (i.e., the person has hammer or claw toes). This may be indicative of damage to, or inflexibility of the plantar fascia caused by excessive flattening of the foot.
Non Surgical Treatment
Your podiatrist will look at your current footwear to ensure that it is both well-fitted and possessed of adequate cushioning to protect your feet. Firm heel support is advised for over-pronators, and a good fit is important to ensure that the foot as a whole is well supported as instability can exacerbate the existing problems caused by over-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.
