Overview
Plantar Fasciitis is a common condition that involves degenerative changes (wear and tear) of the thick fibrous band of tissue that runs from the heel bone beneath the arches through to the ball of the foot. Plantar Fasciitis can be caused by a range of factors including: high impact exercises, excessive body weight, hormonal changes and/or foot biomechanics (foot alignment with weight bearing including high arches or flat feet).
Causes
The arch of the foot is a very complex structure, consisting of multiple bones and ligaments. Most causes of arch pain are related to the anatomy of the arch and the types of physical activity that you perform. For example, a classic set up for arch pain is people who engage in lots of high impact exercise (such as running) while wearing a type of athletic shoe that does not properly support their type of foot arch.
Symptoms
Pain in arch of foot is really the only symptom of this condition. It is unlikely to see any swelling or bruising and instead there will be a deep tender spot near the heel. Occasionally the pain may radiate further down the foot. With this condition, pain will usually be felt first thing in the morning or after periods of sitting. This is because the plantar fascia tightens and shortens slightly when there is no weight on it and by standing on it it suddenly stretches and becomes painful. After a few steps it starts to loosen off and the pain may subside. If this is the same pattern of pain you experience it is quite likely you have plantar fasciits. Pain may also be felt when walking up stairs or standing on tip-toes (anything that stretches the fascia).
Diagnosis
The medical practitioner will examine how the muscles of your foot function. These tests may involve holding or moving your foot and ankle against resistance; you may also asked to stand, walk, or even run. Pain caused by movements may indicate the cause of the pain. The nerves in the foot will be tested to make sure no injury has occurred there. An x-ray, MRI, or bone scan of the foot and arch may be taken to determine if there are changes in the makeup of the bone.
Non Surgical Treatment
The initial treatment for arch pain, especially if it is of sudden onset is the use of ice to reduce the swelling. Later heat and anti-inflammatory gels can be a big help. Activity should be modified, if you stand a lot at work, see if you can using seating more, if you run a lot, consider swimming or cycling for a while. Use footwear that is supportive in the midfoot and heel area.
Surgical Treatment
There are two types of bone procedure for flat feet, those where bone cuts and bone grafts are used to alter the alignment by avoiding any joint structures, or joint invasive procedures (called fusions or arthrodeses) that remove a joint to reshape the foot. With joint fusion procedures, there are those procedures that involve non-essential joints of the foot versus those that involve essential joints. All bone procedures have their place in flat foot surgery, and Dr. Blitz carefully evaluates each foot to preserve as much motion and function while obtaining proper and adequate alignment. In many cases a flat foot reconstruction involves both soft tissue procedures and bone procedures to rebuild and restore the arch. There are several joints in the arch of the foot that can collapse - and these joints are non-essential joints of the foot. This does not mean that they do not have a purpose, but rather become inefficient is providing a stable platform for function. As such, locking these non-essential non-functioning joints into place is commonly recommended. These joints are fused together with screws and/or plates. A heel bone that is no longer in proper position and pushed outwards away from the foot can be corrected with a bone cut and realignment procedure, so long as the displacement is not too significant. A benefit of this surgery is that it keeps the back portion of the foot mobile, and helps the surrounding tendons work for efficiently in maintaining the arch. In certain flat feet, the foot is deviated outwards and away from the midline of the body. Sometimes, this is due to the outer portion of the foot being shorter than the inner portion. Here bone graft can be added to the outer edge of the foot to lengthen the foot to swing the foot over into a corrected position. This procedure is most commonly performed in children and young adults. A bone graft is inserted into the top part of the arch to realign a component of the flat foot, medically known as forefoot varus or medial column elevatus. The back part of the foot (called the rearfoot complex) can be the cause (or source) of the flat foot or the simply affected by the flat foot foot. In simple terms, the back part of the foot can be made to flatten out due to arch problems - and vica versa for that matter. Dr. Blitz specifically identifies the cause of the flat foot as this will determine the best treatment plan, as each flat foot needs to be evaluated individually. The rearfoot is made up of three joints, and depending on the extent and most importantly the rigidity of these joints, they may require fusion to restore alignment. When all three joints require fusion - this call is a triple arthrodesis. For completeness, isolated fusion of any of the three joints can be performed (such as subtalar joint arthrodesis, talonavicular arthrodesis, and calcaneaocuboid joint arthrodesis). The medical decision making for isolated fusions is beyond the scope this article, but Dr. Blitz tries to avoid any rearfoot fusion for flexible feet because these are joints are essential joints of the foot, especially in younger people. Those in severe cases, it may be advantageous to provide re-alignment.
Stretching Exercises
Gastroc stretch. Stand on the edge of a step. Rise slowly on your toes. Lower yourself slowly as far as you can until you feel a stretch in your calf. Don?t roll your foot inward or outward. Hold for 1-2 seconds. Reps:10-20 (stop before you fatigue). Soleus stretch. Same as above, but start with your knee bent so that you feel a slight stretch in your calf or achilles. Maintain the angle of your knee throughout the stretch. Bicycle stretch. Lie on your side. Keeping your top leg straight, bring your knee toward your nose until you feel a slight stretch in the hamstring. Maintaining this angle at your hip, start pretending you are pedalling a bicycle with the top leg. Make sure you feel a slight stretch each time your knee is straight. Reps: 10-30 for each leg. If you feel any pops or clicks in your hip or back, try raising the top leg a little (making the thighs further apart) to eliminate the popping. Foot Intrinsic Exercises. Assisted metatarsal head raising. Sit in a chair. Find the bumps at the ball of your foot just before your big toe and just before the little toe. These are the first (big toe) and fifth (little toe) metatarsal heads. Place your second and third fingers from one hand under the first metatarsal head, and the second and third fingers from the other hand under the fifth metatarsal head. Now lay the thumbs from each hand in a diagonal across your toes so that they form a right angle meeting at the nail of the second toe. Your hands are now in position to assist your toes. Keep your toes straight, with the toe pads on the floor. Use your fingers to help raise all the metatarsal heads (the ball of your foot). Do not let your toes curl under keep them long. Now relax. Reps 7-10 for each foot. As this exercise gets easier, let your fingers do less of the work until your toes can do the exercise unassisted. This can take up to three weeks. When your strength has improved to this point, you can progress to the following three exercises, which are best done in stocking feet on a slippery floor. Active metatarsal head raising. Stand with your weight on both feet. Raise your metatarsal heads (the ball of your foot) while keeping your toes from curling under and maintaining your heel on the ground. Relax. Reps 6-7. Do one foot at a time. If you do more reps than you are ready for, you may well develop cramping in your foot. I once had a client who thought if seven reps were good, 10 were better. For good measure, she did the 10 reps 10 times in a day, and then she was unable to walk the next day from having used a set of muscles she had never exercised before. Don?t overdo it.
