The classic bunion is a bump on the side of the great toe joint. This bump represents an actual deviation of the 1st metatarsal. In addition, there is also deviation of the great toe toward the second toe. In severe cases, the great toe can either lie above or below the second toe.
Bunions result from the long bone in the foot (metatarsal) and the big-toe bone becoming misaligned. The causes are likely to be a combination of genetics, wearing ill-fitting shoes, and the way that we walk or run. Arthritis sufferers are also prone to bunions.
A bunion, also called a hallux valgus, is a bony prominence on the inside of the big toe, caused by a misalignment of the joint. The overlying skin maybe swollen, red and tender. Bunions are often painful and can limit what shoes you can wear.
Your doctor can identify a bunion by examining your foot. Watching your big toe as you move it up and down will help your doctor determine if your range of motion is limited. Your doctor will also look for redness or swelling. After the physical exam, an X-ray of your foot can help your doctor identify the cause of the bunion and rate its severity.
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.
Depending on the severity of the deformity, this osteotomy can be done either at the end of the metatarsal (a distal osteotomy) or if the deformity is more severe, the osteotomy is performed at the base of the first metatarsal (a proximal osteotomy). One of the more common distal metatarsal osteotomies that is performed is called the chevron osteotomy. Typically a small screw is inserted into the bone to hold the metatarsal head in place and speed up bone healing. Following a chevron osteotomy, walking is permitted in a surgical shoe the next day after surgery and the shoe is worn for approximately three to four weeks before a more comfortable walking/running type shoe is worn.
