A bunion, commonly known as a big toe, is a common condition in which the bunion is tilted to the outside of the foot and the first metatarsal is inwardly retracted, mostly due to heredity and shoe discomfort. The bunion is mostly related to heredity and shoe discomfort. Standing for too long, walking too much, and often wearing high heels or pointy shoes are all factors that cause bunion; the patient’s bunion is often symmetrical, the first metatarsal protrudes outward due to long-term friction, localized skin thickening and bursitis, and the second and third metatarsal surfaces are calloused due to friction and weight-bearing. The treatment of bunion includes non-surgical and surgical treatments such as wearing loose shoes, bunion orthotics, orthopedic shoes, etc. Surgical treatments include soft tissue surgery, osteotomy and orthopedic surgery, soft tissue combined with osteotomy and orthopedic surgery, etc. If bunion is present in the foot, it can be treated with a combination of soft tissue surgery and orthopedic surgery. If the bunion is accompanied by other symptoms such as pain and persistent pain, please seek medical advice for standardized treatment.
