A bunion is a bony protrusion on the side of the big toe or in some less common cases on the outside of the small toe. The protrusion at the joint of the base of the toe can become irritated, swollen and painful. As the protrusion becomes larger the toe bends toward the second toe causing further sources of irritation. There appears to be multiple causes of a bunion. Genetically the foot may be shaped such that normal activity puts excessive pressure on the big toe eventually causing a bunion. Some suggest footwear that does not fit properly may also put excessive pressure and cause a bunion. The protrusion may be excessive bone structure or a fluid sac called the bursa that becomes inflamed. In any case the deformity of the toe makes it difficult to find proper fitting footwear, is not a pleasant sight, and can be very painful. Causes
Foot problems typically develop in early adulthood and get worse as the foot spreads with aging. For many people, bunions run in the family. They may be just one of several problems due to weak or poor foot structure. Bunions sometimes develop with arthritis. In people with leg length discrepancies, bunions usually form in the longer leg. Women are especially prone to developing bunions. Years of wearing tight, poorly fitting shoes especially high-heeled, pointed shoes can bring on bunions. Such shoes gradually push the foot bones into an unnatural shape.
Symptoms
Often the bunion is not painful and the individual leads a normal active life. Other times the bunion can be very painful, even debilitating. Pain is usually very achy and typically radiates to the toes and along the arch of the foot. Due to the abnormal positioning of the bones in the foot, sharp nerve pains could also be present.
Diagnosis
A simple visual exam is all it will take for your doctor to determine whether you have a bunion. He or she may also ask you to move your big toe in order to ascertain your range of motion. Your doctor may also look for any inflammation, redness, or pain. X-rays can help your doctor determine the severity and cause of the bunion. Your doctor may also ask you questions about your footwear, the symptoms you are experiencing, and if other family members also suffer from the condition. All these factors will help him or her diagnose you properly.
Non Surgical Treatment
Treatment for bunions ranges from non-surgical to surgical. Conservative, non-surgical treatments are aimed to help alleviate some of the discomfort and pain from the bunion, they will not fix the problem. Some of the recommendations would be shoe modification to make room for the bunion, wearing wide toed shoes, or adding padding and cushioning to your shoes.
Surgical Treatment
There are many different procedures that have been described to correct bunions. The type of operation your foot surgeon recommends to correct your bunion should be dictated by the severity of your bunion deformity and the surgeon?s preference. There are well over 100 different bunion correction procedures described in the orthopaedic literature. However, the broad categories of bunion correction procedures are listed below. Removal of the medial eminence. Distal metatarsal osteotomy (chevron) with great toe soft-tissue tightening (medial capsular tightening and distal soft-tissue repair). Proximal metatarsal osteotomy Ludloff, Cresentic, SCARF, medial opening wedge) with with great toe soft-tissue tightening (medial capsular tightening and distal soft-tissue repair). Lapidus hallux valgus correction (first tarsometatarsal joint fusion) with distal soft tissue procedure. Great Toe Fusion (1st MTP joint arthrodesis). Akin osteotomy (Realignment bone cut at the base of the big toe). Removal of the medial eminence with suture stabilization of the first and second metatarsals. Keller joint arthroplasty (removal of the proximal aspect of the proximal phalanx).
