Bunions are bony bumps that form on the side of the big toe joint or baby toe joint (these are commonly called ?bunionettes? or ?tailor?s bunions?). Bunions most commonly result from one or more of the following factors: genetics, faulty foot mechanics like over-pronation, and/or long periods of time spent in improperly fitting footwear. Bunions can start with audible clicking (called ?crepitus?) and/or stiffness in the affected joint which indicates that the joint surfaces are rubbing together improperly. This may progress to include inflammation, degeneration of the surfaces of the joint, deformity (including bone growth at the joint line and displacement of the toe) and ultimately, loss of range of motion in the joint.
Bunions are caused by pressure on the inside of the forefoot which causes the 1st metatarsal bone in the foot to migrating outwards. Biomechanical factors can contribute to the development of bunions for example if you over pronate where the foot rolls in or flattens excessively which causes the inside of the foot to rub against the shoe. Wearing high heeled shoes regularly also increases the risk of developing the condition . The pressure on the forefoot is increased considerably as the heel is raised up. Age is also a factor as the ligaments lose strength as you get older.
Many people with bunions suffer from discomfort and pain from the constant irritation, rubbing, and friction of the enlargement against shoes. The skin over the toe becomes red and tender. Because this joint flexes with every step, the bigger the bunion gets, the more it hurts to walk. Over time, bursitis or arthritis may set in, the skin on the bottom of the foot may become thicker, and everyday walking may become difficult-all contributing to chronic bunion pain.
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
Your podiatrist can recommend exercises, orthoses (special devices inserted into shoes), shoe alterations or night splints (which hold toes straight over night) which may slow the progression of bunions in children. According to experts, ?conservative? measures such as these may help relieve symptoms, though there is no evidence they can correct the underlying deformity. Orthoses are designed to prevent the problem getting worse by decreasing any biomechanical causes of bunions. In other words, if the biomechanical theory is correct (i.e. if your bunions are caused by the way you walk), orthoses may help you walk in a way that doesn?t exacerbate the problem. But it won?t change the already established shape of your foot. For that, you need surgery.
Procedures are designed and chosen to correct a variety of pathologies that may be associated with the bunion. For instance, procedures may address some combination of removing the abnormal bony enlargement of the first metatarsal, realigning the first metatarsal bone relative to the adjacent metatarsal bone, straightening the great toe relative to the first metatarsal and adjacent toes, realigning the cartilagenous surfaces of the great toe joint, addressing arthritic changes associated with the great toe joint, repositioning the sesamoid bones beneath the first metatarsal bone, shortening, lengthening, raising, or lowering the first metatarsal bone, and correcting any abnormal bowing or misalignment within the great toe. Connecting two parallel long bones side by side by Syndesmosis Procedure. At present there are many different bunion surgeries for different effects. The age, health, lifestyle and activity level of the patient may also play a role in the choice of procedure. Traditional bunion surgery can be performed under local, spinal or general anesthetic. In the case of laser surgery, a narcotic analgesic is typically used. The trend has moved strongly toward using the less invasive local anesthesia over the years. A patient can expect a 6- to 8-week recovery period during which crutches are usually required for aid in mobility. An orthopedic cast is much less common today as newer, more stable procedures and better forms of fixation (stabilizing the bone with screws and other hardware) are used. Hardware may even include absorbable pins that perform their function and are then broken down by the body over the course of months.
Bunions often become painful if they are allowed to progress. But not all bunions progress. Many bunion problems can be managed without surgery. In general, bunions that are not painful do not need surgical correction. For this reason, orthopaedic surgeons do not recommend "preventive" surgery for bunions that do not hurt; with proper preventive care, they may never become a problem.
