Most people with flat feet have a condition that is referred to as a flexible flat foot. This is caused by excessive flexibility within the joints and ligaments of their foot and is often hereditary. This results in an over pronated (rolled in) position and is exaggerated by mechanical misalignment of the foot. This can be a very destructive position for the foot to function in and can cause a wide variety of foot, leg and lower back conditions. The appearance of flat feet may vary from foot to foot. Generally there is a collapse of the medial (inside/middle) long arch of the foot. This may occur mildly where the arch height drops slightly or can be a large movement that results in the entire length of the arch resting on the ground. The twisting and misalignment of the foot that occurs with arch collapse can cause excessive wear and tear of the foot joints and eventually pain.
Causes
Tarsal Tunnel Syndrome develops when there is compression on the tibial nerve as it passes through the tarsal tunnel on the inner side of the ankle bone (medial malleolus). It can cause pain on bottom of foot as well as pins and needles. Numbness in the heel can often extend down to the big toe and adjacent three toes. In addition, it may also produce hot and cold sensations along the bottom of the foot. Tarsal Tunnel Syndrome is caused by anything which occupies space in the tarsal tunnel including cysts, ganglions, bone spurs, swelling from ankle injuries or tumours. Treatment aims to reduce the foot arch pain and usually consists of rest, strengthening and stretching exercises, compression bandages and steroid injections. If the pain in bottom of foot persists, surgery may be required.
Symptoms
Persistant pain and selling under the ball of the foot and extending towards the toes (most commonly the 2nd). Some swelling may be disable on the top of the foot along with redness. Often a sensation of 'walking on the bones for the foot' will be described, and there is a positive Lachman's test. Often a tear will result in the toes splaying (daylight sign) and clawing.
Diagnosis
In a person of any age, the doctor will ask about occupational and recreational activities, previous foot trauma or foot surgery and the type of shoes worn. The doctor will examine your shoes to check for signs of excessive wear. Worn shoes often provide valuable clues to gait problems and poor bone alignment. The doctor will ask you to walk barefoot to evaluate the arches of the feet, to check for out-toeing and to look for other signs of poor foot mechanics.
Non Surgical Treatment
Stretch the fascia. Prop your toes up against a wall, keeping your arch and heel flat so the toes stretch. Hold for a count of 10. Repeat 10 times three or four times per day. Roll a frozen water bottle under the arch. Stretch first then roll out the arch for 10 minutes; you don?t want to stretch the tendon when it?s ice cold. Freeze a golf ball and massage the fascia. Roll the frozen golf ball under the foot, starting from the front and working your way back. Put good pressure on each spot-the medial, center and lateral positions-for 15 seconds before moving to the next area. Then, roll the ball back and forth over the entire foot. Foam roll all muscles on the body above the plantar. Even tight shoulders can cause the condition, as your arm swing can throw off proper hip alignment and footstrike. Bump your arch. Get a commercial insole with an arch bump to push on the plantar and keep it from flexing-it doesn?t matter if you?re an under or overpronator; the plantar needs to be supported and strengthened, Wear the support in all shoes, if possible.
Surgical Treatment
As with most surgeries, patients and physicians should consider the surgery only after other, less invasive treatments have proven unproductive. Indications for surgery include Pain. Inability to function. Failure to improve after a six-month course of specific, directed physical therapy. Failure to improve after using arch supports, orthotics, or ankle and foot bracing. Once patients are at that point, the good news is that the procedure has considerably better outcomes than more traditional flat foot surgery. In the past, surgeons would realign and fuse the three hind joints, which would cause patients to lose motion, leaving them with a significantly stiff hind foot, With these newer procedures, if the foot is still flexible, surgeons can realign it and usually restore a close-to-normal or functional range of motion in the joints.
Prevention
Maintain a healthy weight, Use insoles to support your arches, Limit how often you wear high heels, Use proper shoes, especially when exercising to evenly distribute weight through your foot.
