Bunion, the outward deviation of the toe beyond its normal angle, is one of the most common lesions of the forefoot. In terms of its pathogenesis, about 50% of people with bunions have a family history of the condition. These people show bunion deformity from a young age, but do not have any painful discomfort, so few people consider it a disease. In fact, exceeding the normal value is abnormal and it can be considered as a pathology. 1, with the aggravation of the degree of bunion, the 1st metatarsal inversion also becomes more and more serious, the 1st metatarsal head at the extrusion, friction aggravation, local bursa thickening, bone superfluous proliferation to form large bone abduction. The forefoot becomes significantly wider, making it difficult for these people to choose a pair of suitable and beautiful shoes, and with the advent of hot summer, they cannot wear sandals because they feel that their feet are not beautiful or even ugly. 2.Due to long-term friction, the soft tissue on the inside of the first metatarsal head grows and becomes hypertrophied, producing local aseptic inflammation forming bursitis and severe pain, which affects walking. 3, due to the bunion to the lateral deflection, the 2nd toe back up, the rest of the toe by the extrusion from the outside of the shoe, resulting in 2-4 toes like a chicken claw deformity, so that the dorsal side of the toe by friction, can form corns, most often seen in the 2, 4 toes dorsal side; at the same time, due to toe deformity, the metatarsal head will be low collapse, and will be in the metatarsal head foot bottom to form the foot pad, this situation is most often seen in the 2nd toe bone foot bottom. Corns, foot pad will have severe pain, and recurring episodes, affecting normal life and work of. 4, due to the widening of the forefoot, the collapse of the transverse arch, walking more or less will appear the situation of foot valgus, so that the weight-bearing surface of the ankle joint will cause changes, will cause traumatic inflammation of the ankle joint, pain, and even affect the knee joint, hip joint and even the waist. 5. Similarly, the athletic ability of these people is seriously affected due to the widening of the forefoot, collapse of the transverse arch, cushioning shock of the foot as well as reduced bouncing ability of the foot. In conclusion, bunions are not only a pathology in themselves, but also have complications that can affect people’s lives. As a disease, bunions do not cause much discomfort in the early stages, except for unattractive appearance, difficulty in choosing shoes and the tendency to damage the shape of shoes. However, as people grow older and the bunion deformity increases, many serious complications will arise, such as bunions, claw toes, corns, foot pads, etc.; these complications not only affect the function of the foot, but also produce pain, which seriously affects life and work. Therefore, it is recommended that when a bunion deformity is found, it is best to prevent and treat it early so that not only can the deterioration of the bunion be delayed, but also some complications can be effectively prevented. Specific prevention and control measures are as follows: 1. Choose a pair of suitable shoes, such as shoes with a heel that is not too high and a loose toe, so that the toes have some space to move around in, so that they do not feel any pressure, especially not to wear high heels that are sharp and thin. 2. Do barefoot exercises to strengthen the plantar muscles and slow down the deterioration of bunions. 3, Daily finger wrenching of the bunion to the inside can also effectively prevent the bunion from worsening. 4.With the help of some orthopedic devices, such as bunion orthoses (divided into day and night orthoses) wearing bunion orthoses for a long time has a certain therapeutic effect on bunions. 5, when the above conservative treatment can not be effectively corrected, surgery should be taken, which is the most effective treatment method. Early bunion deformity is not very serious, such as let it develop can appear so many comorbidities, such as bunions, foot metatarsal phalangeal joint dislocation, pain. Early surgical treatment will reduce the number of comorbidities, and because the deformity is not very serious, the operation is relatively simple and the postoperative results are better.
