Abstract
This article reports the diagnosis and treatment of a 50-year-old female patient with systemic sclerosis complicated by a nonhealing wound on her left hand. Following comprehensive treatments including debridement, vacuum sealing drainage, ozone therapy, skin grafting, and phalangeal fusion, the wound healed successfully. This article highlights the potentially contradictory role of interleukin-6 inhibitors in the treatment of patients with systemic sclerosis and ulcers as well as emphasizes the application value of ozone therapy in improving tissue hypoxia and promoting healing.
