Although burn treatment technology has been greatly improved, the number of patients with hypertrophic scar contracture deformities after burn has not decreased significantly. Some patients still have severe deformities, which not only affect the appearance, but also lead to different degrees of dysfunction. Surgery is still dominant for treating hypertrophic scar contracture deformity. In addition to skin grafting, flaps, especially expanded flaps (perforator flaps), expanded free flaps (perforator flaps), and prefabricated flaps etc. are more frequently used in functional and exposed areas after scar excision, in order to achieve perfect repair and reduce donor site damage. The treatment of scar contracture deformity should take into account the rehabilitation after operation on the basis of active operation, so as to achieve the unity of shape and function.
