Hallux Abducto Valgus, commonly called bunion, is a bony deformity affecting the angle of the joint at the base of the big toe. Some medical professionals believe that the condition is solely due to ill-fitting footwear, while others believe it is a genetic structural defect that can be exacerbated by shoes. Despite the varying opinions, the reality is that it is probably a combination of both factors. A bunion forms when pressure is applied to the side of the big toe, causing it to become inflamed and painful. The joint then protrudes, effectively making the foot wider. The second toe might then become displaced, which can cause a multitude of other issues like corn and callus development. The bunion joint will have a reduced range of motion and often ends up arthritic. The condition usually develops later in life.
The most common cause of bunions is wearing shoes that are too tight. The condition is not hereditary, but it does tend to run in families-often due to a faulty foot structure. Other causes of this condition might be neuromuscular problems, flat feet, pronated feet, or foot injuries.
The dominant symptom of a bunion is a big bulging bump on the inside of the base of the big toe. Other symptoms include swelling, soreness and redness around the big toe joint, a tough callus at the bottom of the big toe and persistent or intermittent pain.
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
A bunion treatment must address the underlying cause of the deformity, not just the bump (bunion) itself but also the functions of the foot. The up and down motion of the longitudinal arches in the foot. The sideways motion of the transverse arch. Bunion aids effectively treat this underlying foot function while straightening the big toe because the mid-foot strap stabilizes the longitudinal arches and transverse arch. The toe strap gradually and gently pulls the big toe away from the second toe. The metatarsal pad helps align the transverse arch. The hinged splint enables the big toe to flex while walking and adapts to the contour of the foot, especially around the inflamed area of the joint.
If all nonsurgical measures fail to control the symptoms, then surgery may be suggested to treat the hallux valgus condition. Well over 100 surgical procedures exist to treat hallux valgus. The basic considerations in performing any surgical procedure for hallux valgus are to remove the bunion, to realign the bones that make up the big toe, to balance the muscles around the joint so the deformity does not return.
