Hallux valgus, also known as a bunion, is a deformity of the foot where the first metatarsal bone and great toe are misaligned. It occurs more frequently in females and risk increases with age, and may be genetic. Symptoms include pain, calluses, reduced range of motion. Conservative treatment focuses on supportive shoes while surgical correction realigns bones. Postoperative care involves elevation, limited activity, pain medication, and bandage changes to aid healing.
