Overview
The big toe of the foot is called the hallux. If the big toe starts to deviate inward in the direction of the baby toe, the condition is called hallux valgus. As the big toe drifts over into valgus, a bump starts to develop on the inside of the big toe over the metatarsal bone. This bone prominence on the inner edge for the metatarsal is referred to as a bunion.
Causes
Bunions are more common in women than men. The problem can run in families. People born with abnormal bones in their feet are more likely to form a bunion. Wearing narrow-toed, high-heeled shoes may lead to the development of a bunion. The condition may become painful as the bump gets worse. Extra bone and a fluid-filled sac grow at the base of the big toe.
Symptoms
The signs and symptoms of a bunion include a bulging bump on the outside of the base of your big toe, swelling, redness or soreness around your big toe joint, Thickening of the skin at the base of your big toe, Corns or calluses, these often develop where the first and second toes overlap, persistent or intermittent pain, restricted movement of your big toe. Although bunions often require no medical treatment, see your doctor or a doctor who specializes in treating foot disorders (podiatrist or orthopedic foot specialist) if you have persistent big toe or foot pain, a visible bump on your big toe joint, decreased movement of your big toe or foot, difficulty finding shoes that fit properly because of a bunion.
Diagnosis
Physical examination typically reveals a prominence on the inside (medial) aspect of the forefoot. This represents the bony prominence associated with the great toe joint ( the medial aspect of the first metatarsal head). The great toe is deviated to the outside (laterally) and often rotated slightly. This produces uncovering of the joint at the base of the big toe (first metatarsophalangeal joint subluxation). In mild and moderate bunions, this joint may be repositioned back to a neutral position (reduced) on physical examination. With increased deformity or arthritic changes in the first MTP joint, this joint cannot be fully reduced. Patients may also have a callus at the base of their second toe under their second metatarsal head in the sole of the forefoot. Bunions are often associated with a long second toe.
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.
Surgical Treatment
Bunionectomy is a general term that describes a variety of bone and soft tissue procedures that are intended to realign your big toe and reduce the prominence at the base of your big toe. The procedures chosen are based on numerous factors, including measured angular displacement of your involved joints (especially your first MTP joint). The degree of pain you are experiencing. The degree of joint dislocation and cartilage damage within your affected joint. Flexibility of your adjacent joints. Flexibility of soft tissues in your problem area.
