A bunion is a bony prominence on the side of the foot, at the base of the big toe joint. This enlargement of the joint, spurring, bump or lump can be aggravated by sports and tight shoes. There is progressive movement of the big toe outward, toward the other toes. As the ?bump? gets bigger, shoes can increase pressure on the base of the big toe causing more and more discomfort or pain. The term Hallux Valgus is the medical name for this condition.
Bunions are most often caused by faulty mechanics of the foot. The deformity runs in families, but it is the foot type that is hereditary, not the bunion.Certain foot types make a person prone to developing a bunion. Injury can be a cause, especially if just one foot is involved. Although wearing shoes that crowd the toes won?t actually cause bunions in the first place, it can make the deformity progressively worse. That means you may expererince symptoms sooner.
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.
Orthopaedic surgeons diagnose bunions on the basis of physical examination and weight bearing x-rays. Two angles are assessed, the intermetatarsal angle, that is between the first and second metatarsals (the bones that lead up to the base of the toes). If this angle exceeds 9? (the angle found in the healthy foot) it is abnormal and referred to as metatarsus primus varus. the hallux valgus angle, that is, the angle of the big toe as it drifts toward the small toe. An angle that exceeds 15? is considered to be a sign of pathology.
Non Surgical Treatment
Bunions are progressive problems, meaning they tend to get worse over time. Sometimes severe-looking bunions don't hurt much, and sometimes relatively modest-looking bunions hurt a great deal. Thus, treatment varies depending upon a patient's symptoms. You can often improve the discomfort of bump pain by a change to more proper shoes. Alternatively, alterations to existing shoes may improve pain associated with bunions. Accommodative padding, shields and various over-the-counter and custom-made orthopaedic appliances can also alleviate bunion pain. Anti-inflammatory medications, steroid injections, physiotherapy, massage, stretching, acupuncture and other conservative treatment options may be recommended by your podiatric physician to calm down an acutely painful bunion. Long term, orthoses (orthotics) can address many of the mechanical causes of a bunion. Thus, while orthoses don't actually correct a bunion deformity, if properly designed and made, they can slow the progression of bunions. They can also be made to redistribute weight away from pain in the ball of the foot, which often accompanies bunion development. Padding, latex moulds and other accommodative devices may also be effective. While they don't correct the misalignment in the bones, they may alleviate pain. Often, though, when conservative measures fail to alleviate pain associated with the bunion, when you start to limit the types of activities you perform, when it's difficult to find comfortable shoes, and when arthritis changes how you walk, surgery may be the best alternative.
As you explore bunion surgery, be aware that so-called "simple" or "minimal" surgical procedures are often inadequate "quick fixes" that can do more harm than good. And beware of unrealistic claims that surgery can give you a "perfect" foot. The goal of surgery is to relieve as much pain, and correct as much deformity as is realistically possible. It is not meant to be cosmetic. There are several techniques available, often as daycare (no in-patient stay), using ankle block local anaesthetic alone or combined with sedation or full general anaesthesia. Most of the recovery occurs over 6-8 weeks, but full recovery is often longer and can include persistent swelling and stiffness. The surgeon may take one or more of the following steps in order to bring the big toe back to the correct position: (a) shift the soft tissue (ligaments and tendons) around the joint and reset the metatarsal bone (osteotomy), remove the bony bump and other excess bone or (b) remove the joint and connect (fuse) the bones on the two side of the joint (fusion). These are just a few examples of the many different procedures available and your treating surgeon can help you decide the best option for you.
