A hallux abducto valgus deformity, commonly called a bunion, is a deformity characterized by medial deviation of the great toe, often erroneously described as an enlargement of bone or tissue around the joint at the head of the big toe. There is disagreement among medical professionals about the cause of bunions; some see them as primarily caused by the long-term use of shoes, particularly tight-fitting shoes with pointed toes, while others believe that the problem stems from genetic factors that are exacerbated by shoe use. Bunions occur when pressure is applied to the side of the big toe (hallux) forcing it inwards towards, and sometimes under or over, the other toes (angulation). As pressure is applied, the tissues surrounding the joint may become swollen and tender. In a survey of people from cultures that do not wear shoes, no cases of bunions were found, lending credence to the hypothesis that bunions are caused by ill-fitting shoes. The bump itself is partly due to the swollen bursal sac or an osseous (bony) anomaly on the metatarsophalangeal joint. The larger part of the bump is a normal part of the head of the first metatarsal bone that has tilted sideways to stick out at its top.
People born with abnormal bones (congenital) in their feet. Inherited foot type. Foot injuries. Inflammatory or degenerative arthritis causing the protective cartilage that covers your big toe joint to deteriorate. Wearing high heels forces your toes into the front of your shoes, often crowding your toes. Wearing shoes that are too tight, too narrow or too pointed are more susceptible to bunions. Pain from arthritis may change the way you walk, making you more susceptible to bunions. Occupation that puts extra stress on your feet or job that requires you to wear ill-fitting shoes. The tendency to develop bunions may be present because of an inherited structural foot defect.
SymptomsMovement of the big toe towards the smaller toes. Bulging bump on the outside of the base of the big toe. Restricted movement of the big toe. Swelling, inflammation, redness or soreness around your big toe joint. Persistent or sporadic dull, sharp or aching pain in or around the big toe. Corns, blisters and calluses which can develop when the first and second toes overlap. Over time, more severe symptoms can occur such as arthritis of the big toe, stress fractures and problems walking.
A thorough medical history and physical exam by a physician is necessary for the proper diagnosis of bunions and other foot conditions. X-rays can help confirm the diagnosis by showing the bone displacement, joint swelling, and, in some cases, the overgrowth of bone that characterizes bunions. Doctors also will consider the possibility that the joint pain is caused by or complicated by Arthritis, which causes destruction of the cartilage of the joint. Gout, which causes the accumulation of uric acid crystals in the joint. Tiny fractures of a bone in the foot or stress fractures. Infection. Your doctor may order additional tests to rule out these possibilities.
Non Surgical Treatment
Technically, you can only ?fix a bunion? with surgery, but many patients don’t need it to get symptom relief. In its early stages, the progression of the bunion deformity can often be dramatically slowed. Removing pressure from the bunion area and balancing the tendon and ligament alignment are the primary goals of mild bunion treatment. For example, it is important to wear shoes that have sufficient room in the toe area to accommodate the bunion – that means softer leather shoes to mold to the deformity and platform type heels for better foot and arch support. Your doctor may also advise the use of pads to protect the bunion from shoe pressure. Customized shoe inserts, called orthotics are made exclusively for your foot and are often used to correct the alignment of the arch and big toe joint. In some cases, physicians also use anti-inflammatory creams around the bunion.
When the pain of a bunion interferes with daily activities, and conservative treatment has been completed it’s time to discuss surgical options. Foot Mechanics has excellent relationships with many Orthopaedic Surgeons, who are the specialists who perform bunion surgery. Because bunions are caused by faulty foot mechanics surgery can improve the look of your feet by removing the ?bump? but if the underlying mechanics are not addressed then the bunion is likely to return. For this reason orthotics are used post-surgery to prevent the return of bunions.
