If the mechanics of your feet are a little bit off, it can throw off the alignment of your entire body.Įxcessive supination can cause ankle pain, plantar fasciitis and stress higher up the body. This can also have far more far-reaching adverse affects. When your ankle rolls outward you put stress on vulnerable parts of your feet and ankles. The body is a complex interlinked system that starts at the feet. Supination is commonly a result of genetics but can also be triggered or worsened by muscle imbalances in the foot, ankle and lower leg. When you supinate, the ankle rolls outward, causing extra stress on the foot and ankle. In a normal step, your foot should roll inward a small amount (pronate) so that your weight is on the ball of your foot, allowing you to push off from your big toe. Special shoes or braces are the best method for dealing with this problem.Supination occurs when your weight rolls onto the outer edges of your feet as you take a step. This may result in a severely deformed foot that is very challenging to correct with surgery. In addition to the ligaments not holding the bones in place, the bones themselves can sometimes fracture and disintegrate - without the patient feeling any pain. This is because patients do not feel pain as the arch collapses. This type of arch collapse is typically more severe than that seen in patients with normal feeling in their feet. People with diabetes or with a nerve problem that limits normal feeling in the feet, can have arch collapse. In addition to ligament injuries, fractures and dislocations of the bones in the midfoot can also lead to a flatfoot deformity.įor more information about injuries to the midfoot: Lisfranc (Midfoot) Injuries Diabetic Collapse (Charcot Foot) This more commonly occurs in the middle of the foot (Lisfranc injury), but can also occur in the back of the foot. If the ligaments are torn, the foot will become flat and painful. The ligaments support the bones and prevent them from moving. The arthritis can affect the back of the foot or the middle of foot, both of which can result in a fallen arch.įor in-depth information about rheumatoid arthritis of the foot: Rheumatoid Arthritis of the Foot and Ankle InjuryĪn injury to the ligaments in the foot can cause the joints to fall out of alignment. Inflammatory arthritis not only causes pain, but also causes the foot to change shape and become flat. This type of arthritis attacks not only the cartilage in the joints, but also the ligaments that support the foot. Inflammatory arthritis, such as rheumatoid arthritis, can cause a painful flatfoot. In addition, people who are involved in high impact sports, such as basketball, tennis, or soccer, may have tears of the tendon from repetitive use.įor in-depth information on posterior tibial tendon dysfunction: Posterior Tibial Tendon Dysfunction Arthritis Having flat feet since childhood increases the risk of developing a tear in the posterior tibial tendon. Other risk factors include obesity, diabetes, and hypertension. Women and people over 40 are more likely to develop problems with the posterior tibial tendon. The posterior tibial tendon attaches the calf muscle to the bones on the inside of the foot. #Foot turning outward in adults skinThe large bump can cause skin problems and an ulcer (a sore that does not heal) may develop if proper diabetic shoewear is not used. Because their sensation is affected, people with diabetes may not have any pain. Diabetics may only notice swelling or a large bump on the bottom of the foot.Occasionally, the bony spurs are so large that they pinch the nerves which can result in numbness and tingling on the top of the foot and into the toes. Patients with an old injury or arthritis in the middle of the foot can have painful, bony bumps on the top and inside of the foot.Arthritis in the heel also causes this same type of pain. This can cause pain on the outside of the ankle. When the foot collapses, the heel bone may shift position and put pressure on the outside ankle bone (fibula).Some patients can have difficulty walking or even standing for long periods of time. High intensity or impact activities, such as running, can be very difficult. This can be associated with swelling on the inside of the ankle.
