Managing With Bunions
Overview
A bunion is a deviation and inflammation of joint where the big toe connects to the 1st metatarsal, also known as the 1st MTP. The capsule of the joint is displaced, thickened and enlarged, and the cartilage of the joint is damaged. There are three degrees of bunions: mild, moderate and severe. It is important to know that bunions are not hereditary, although the tendency to overpronate, which is one of the main causes of bunions, has a hereditary component. Patients complain of pain in the joint and have a big toe that points away from the midline of the body. Often, they are only able to wear very wide shoes.
Causes
Bunions have a number of causes, primarily genetics and bad choices in footwear. We inherit traits like flat feet, abnormal bone structure, and loose ligaments and tendons from our parents. When our feet are weakened by these traits and we stuff them into high heels or shoes which don?t support our feet correctly, the repeated stress on the front of the foot may contribute to the formation of a bunion. Other contributing factors are jobs that demand a lot of time standing, obesity, and sudden hormonal changes and weight gain, as in pregnancy. Unfortunately, bunions can lead to many other foot conditions as well. The joint behind the big toe carries much of your body weight and when the bunion makes it sore, you shift your weight onto other areas of the foot. That?s why we frequently see crossover toes, overlapping toes, hammer toes, corns, calluses, and ingrown toenails accompanying bunions. As pain in your foot increases, you?ll also reduce your activity, becoming more sedentary, which has its own quality-of-life issues.
Symptoms
The symptoms of a bunion include the following development of a firm bump on the outside edge of the foot, at the base of the big toe, redness, swelling, or pain at or near the MTP joint, corns or other irritations caused by the overlap of the first and second toes, restricted or painful motion of the big toe.
Diagnosis
Most patients are diagnosed to have bunions from clinical history and examination. However, in some cases, X-rays will be performed to determine the extent of damage to the joint. Furthermore, it will enable the treating doctor to decide on the best course of management of the patient.
Non Surgical Treatment
Sometimes observation of the bunion is all that's needed. A periodic office evaluation and x-ray examination can determine if your bunion deformity is advancing, thereby reducing your chance of irreversible damage to the joint. In many other cases however some type of treatment is needed. Early treatments are aimed at limiting the progression of the deformity and easing the pain of bunion or an associated joint. Conservative treatments such as orthotics can achieve this but they won't reverse the deformity itself. These options include changes in shoewear. Padding. Pads placed over the area of the bunion can help minimise pain, but will not stop the progression of the bunion. Activity modifications. Avoid activity that causes bunion pain, this could include standing for long periods of time. Medications. Nonsteroidal anti-inflammatory drugs (NSAIDs), such as ibuprofen, may help to relieve pain. Icing. Applying an ice pack several times a day helps reduce inflammation and pain. Orthotic devices. Orthotics are the mainstay of non-surgical treatment for bunions. 
Surgical Treatment
The type of surgical procedure performed depends upon the severity of the bunion, the individual?s age, general health, activity level, and the condition of the bones and connective tissue. Other factors may influence the choice of a procedure used. Mild bunion. For this type of surgery, the surgeon may remove the enlarged portion of bone and realign the muscles, tendons, and ligaments surrounding the joint. Moderate bunion. For a moderate bunion, the surgeon may cut the bone and shift it to its proper position. Whether or not the bone is cut depends on the severity and location of the deformity. In addition, the surrounding tendons and ligaments may need to be repositioned. Severe bunion. For a severe bunion, surgery may involve removing the enlarged portion of the bone, cutting and realigning the bone, and correcting the position of the tendons and ligaments. Arthritic bunion or big toe joint. If the joint is damaged beyond repair, as is commonly seen in arthritis, it may need to be reconstructed or replaced with an artificial joint. Joint replacement implants may be used in the reconstruction of the big toe joint.
Prevention
The simplest way to reduce your chance of developing foot bunion or bunionette problems is to wear good-fitting shoes. Avoid high heels as they push your feet forwards to the front of the shoe where they get squashed. Also avoid narrow fitting shoes, especially those that are pointed at the front with a narrow toe box as again, these place pressure through the toes pushing them inwards. Shoes should be comfortable and leave enough room for you to wiggle your toes. Remember, bunions rarely affect non-shoe wearing people. Exercising your feet can also help. By strengthening the foot muscles you can improve your foot position which can help reduce foot bunion problems. Simple exercises like picking up small objects with your toes can help.
Over-Pronation Of The Feet Cause And Treatment
Overview
Overpronation still continues to be misused and misunderstood. For example, there was a study that got a lot of recent mileage in the mainstream media and the blogosphere that claimed to show that foot pronation was not associated with injury risk. It was intriguing following comments on the study in mainstream media and in social media, especially the parroting of the press release without any critical appraisal. The study actually eliminated the ?overpronators? that were probably at high risk from the study then found that ?overpronation? was not a risk factor. What is more intriguing was that there was another study from around the same time that found the exact opposite. Clearly, the data on ?overpronation? and risk for injury in runners is mixed, so we need to rely on the more formal systematic reviews and meta-analyses of all the data. The most recent one of those concluded that ?overpronation? is just a small risk factor for running injury risk, but it is still statistically significant.
Causes
There are many causes of flat feet. Obesity, pregnancy or repetitive pounding on a hard surface can weaken the arch leading to over-pronation. Often people with flat feet do not experience discomfort immediately, and some never suffer from any discomfort at all. However, when symptoms develop and become painful, walking becomes awkward and causes increased strain on the feet and calves.
Symptoms
Not all foot injuries affecting runners are necessarily down to a particular running gait; it is rarely that simple to diagnose how a foot problem developed . Simply being an overpronator does not mean that a foot injury has been caused by the running gait and it could be due to a number of factors. However mild to severe overpronators tend to be at a higher risk of developing musculoskeletal problems due to the increased stresses and strains which are placed on the body when the foot does not move in an optimum manner. The following injuries are frequently due to overpronation of the feet. Tarsal tunnel syndrome. Shin splints. Anterior compartment syndrome. Plantar fasciitis. Achilles tendonitis. Bunions. Sesamoiditis. Stress fractures. Back and hip pain. Ankle pain.
Diagnosis
You can test for pronation by looking at the leg and foot from the back. Normally you can see the Achilles Tendon run straight down the leg into the heel. If the foot is pronated, the tendon will run straight down the leg, but when it lies on the heel it will twist outward. This makes the inner ankle bone much more prominent than the outer ankle bone.
Non Surgical Treatment
Heel counters that make the heel of the shoe stronger to help resist/reduce excessive rearfoot motions. The heel counter is the hard piece in the back of the shoe that controls the foot?s motion from side-to-side. You can quickly test the effectiveness of a shoe?s heel counter by placing the shoe in the palm of your hand and putting your thumb in the mid-portion of the heel, trying to bend the back of the shoe. A heel counter that does not bend very much will provide superior motion control. Appropriate midsole density, the firmer the density, the more it will resist motion (important for a foot that overpronates or is pes planus), and the softer the density, the more it will shock absorb (important for a cavus foot with poor shock absorption) Wide base of support through the midfoot, to provide more support under a foot that is overpronated or the middle of the foot is collapsed inward.
Surgical Treatment
Subtalar Arthroereisis. The ankle and hindfoot bones/midfoot bones around the joint are fused, locking the bones in place and preventing all joint motion. This may also be done in combination with fusion at other joints. This is a very aggressive option usually reserved for extreme cases where no joint flexibility is present and/or the patient has severe arthritic changes in the joint.
