A bunion is an enlargement of bone at the great toe joint. Tight shoes don’t cause bunions, but they can aggravate them. Bunions are often inherited and become worse over time if left untreated they can cause pain, swelling, skin irritation and other foot problems. Bunion deformities are often part of a more generalized problem related to improper foot motion. There are presently over 25 types of bunion procedures performed today. The choice of procedure is based on many factors.
Bunions can be caused by improper footwear. Genetics. Foot injuries. Congenital deformities. Medical conditions such as arthritis. Stress on feet. Bunions are mainly caused by genetics. The bunion itself is not inherited, but the person?s hereditary foot type and gait pattern makes them more prone to developing bunions.You can also begin to develop bunionsby wearing shoes that are too tight or too small. When you wear shoes of this nature, your toes are squeezed together. Bunions are not caused by crowding of the toes, but wearing tight shoes can worsen the condition and cause symptoms to appear sooner. Some people are born with birth defects that put them at higher risk for developing bunions.
SymptomsWith the positional change of the hallux, pain is a common occurrence. As the foot goes through the gait cycle the hallux plays an integral role as the body’s weight transmits through during propulsion. With this in mind, it easy to see how the change in the hallux joints (metatarsal phalangeal joint and the proximal interphalangeal) would cause joint narrowing and early degeneration of the articular cartilage. In addition, two small bones (ossicles) found underneath just behind the joint will start placing extra pressure on the metatarsal. Along with bony changes, there are many soft tissue changes as the hallux and metatarsal reposition, which causes added strain to other bony structures and can accelerate the problem.
Most patients are diagnosed to have bunions from clinical history and examination. However, in some cases, X-rays will be performed to determine the extent of damage to the joint. Furthermore, it will enable the treating doctor to decide on the best course of management of the patient.
Non Surgical Treatment
Your podiatrist can recommend exercises, orthoses (special devices inserted into shoes), shoe alterations or night splints (which hold toes straight over night) which may slow the progression of bunions in children. According to experts, ?conservative? measures such as these may help relieve symptoms, though there is no evidence they can correct the underlying deformity. Orthoses are designed to prevent the problem getting worse by decreasing any biomechanical causes of bunions. In other words, if the biomechanical theory is correct (i.e. if your bunions are caused by the way you walk), orthoses may help you walk in a way that doesn?t exacerbate the problem. But it won?t change the already established shape of your foot. For that, you need surgery.
The most significant portion of the bunion surgery is re-aligning the bones. This is performed though bone cuts or a fusion involving the first metatarsal. The severity of the bunion determines where the bone will be cut or fused. Mild or moderate bunions can be corrected close to the big toe joint. Moderate or large bunions often require that the bone work be performed further away from the big toe joint to swing the bone in the proper position.
