Bunions are a common problem that most people experience as a bony protuberance at the base of the big toe. A bunion, however, is more complicated than simply a bump on the foot. When a patient has a bunion, the big toe angles in towards the other toes, a condition called hallux valgus. Bunions are most common in women. The skin over your big toe may be red and tender. Wearing any type of shoe may be painful. This joint flexes with every step you take. Your big toe may angle toward your second toe, or even move all the way under it. The skin on the bottom of your foot may become thicker and painful. Pressure from your big toe may force your second toe out of alignment, sometimes overlapping your third toe. If this condition gets severe, it may be difficult to walk. Your pain may become chronic and you may develop arthritis. Bunions tend to get progressively worse over time without treatment.
Contributing factors may include excessive foot pronation, wearing tight and pointed-toe shoes, and occasionally trauma. Joint misalignment causes osteoarthritis with cartilage erosion and exostosis formation, resulting in joint motion being limited (hallux limitus) or eliminated (hallux rigidus). In late stages, synovitis occurs, causing joint swelling. In reaction to pressure from tight shoes, an adventitious bursa can develop medial to the joint prominence, which can become painful, swollen, and inflamed.
The most obvious symptoms of a bunion are. Pain in the area of the MTP joint, the joint where your big toe connects to your foot. Bending of the big toe in towards the other toes. An enlarged bump of bone or tissue at the MTP joint. Each symptom can range in degree from small to severe. Sometimes the pain can be sufficient to make it difficult to walk in normal shoes. Other symptoms may include. Swelling and inflammation of the skin around the MTP joint. Thickening of the skin in the area of the joint. Restricted motion in your big toe. Pressure from the inward bending of your big toe can affect your other toes, leading to corns on your smaller toes. Ingrown toenails on the smaller toes. Development of hammertoes in the other toes. Calluses on the bottom of your foot. If you have any of these symptoms, especially pain, displacement of your big toe or development of a bulge, you should consider consulting your physician. Even if you're not significantly bothered by some of these symptoms, bunions tend to continue getting bigger and more serious over time and should be taken care of before they do so.
X-rays are the best way to determine the amount of deformity of the MTP joint. Blood work may be required to rule out other diseases that may be associated with bunions such as rheumatoid arthritis. Other tests such as bone scans or MRI's are not usually required.
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.
Arthrodesis involves fusing together two bones in your big toe joint (metatarsophalangeal joint). The procedure is usually only recommended for people with severe deformities of the big toe joint, which make it too difficult for doctors to completely fix the joint, or when there's advanced degeneration of the joint. After arthrodesis, the movement of your big toe will be severely limited and you won't be able to wear high heels. An excision arthroplasty involves removing the bunion and the toe joint. A false joint is created by scar tissue that forms as a result of the operation. The procedure involves pinning the joint in place with wires, which will be removed around three weeks after surgery is carried out. An excision arthroplasty can only be used in certain circumstances, and is usually reserved for severe, troublesome bunions in elderly people.
