The sequelae of bunion surgery mainly include the following aspects: first, bunion inversion: if overkill occurs in the process of surgery, it will lead to the occurrence of bunion deformity and cause toe dysfunction. Second, affecting the weight-bearing function: In the process of osteotomy treatment, immobilization is required, and delayed healing, non-healing, or even deformed healing of the fracture may occur after the operation, leading to further changes in the line of force of the bunion and affecting the weight-bearing function. Thirdly, stiffness of the bunion joint: After bunion surgery, it may also lead to stiffness of the bunion joint, affecting the flexion and extension of the toes as well as the weight-bearing function. Therefore, bunion surgery is relatively complicated. If not treated carefully, bunion surgery is prone to serious sequelae, resulting in a significant decline in the patient’s quality of life and athletic ability.
