A bunion is an enlargement of bone or tissue around the joint at the base of the big toe. The big toe may turn toward the second toe. The tissues around the joint may be swollen and tender. A bony bump at the base of the little toe is called a bunionette or tailor's bunion. The little toe also bends inward, and the joint swells or enlarges.
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.
SymptomsRed, thickened skin along the inside edge of the big toe. A bony bump at this site. Pain over the joint, which pressure from shoes makes worse. Big toe turned toward the other toes and may cross over the second toe.
A doctor can very often diagnose a bunion by looking at it. A foot x-ray can show an abnormal angle between the big toe and the foot. In some cases, arthritis may also be seen.
Non Surgical Treatment
Treatment of hallux valgus nearly always starts with adapting shoe wear to fit the foot. In the early stages of hallux valgus, converting from a shoe with a pointed toe to a shoe with a wide forefoot (or toe box) may arrest the progression of the deformity. Since the pain that arises from the bunion is due to pressure from the shoe, treatment focuses on removing the pressure that the shoe exerts on the deformity. Wider shoes reduce the pressure on the bunion. Bunion pads may reduce pressure and rubbing from the shoe. There are also numerous devices, such as toe spacers, that attempt to splint the big toe and reverse the deforming forces.
One of the more popular proximal metatarsal osteotomies that is performed is called the Myerson/Ludloff procedure. This operation is performed for more advanced deformity. Screws are inserted into the metatarsal to hold the bone cut secure and speed up bone healing. Walking is permitted in a surgical shoe following surgery. The shoe is worn approximately 5 weeks.
