Sclerosis of the broken end of ankle fracture generally indicates that there may be a risk of non-union of the fracture, which can be treated by conservative treatment, surgery and other methods. 1. Conservative treatment: If the time after fracture is not long, conservative treatment can be taken first, such as local microwave, ultra-short wave and other physical therapy to promote blood circulation and stimulate bone growth, and at the same time, rehabilitation exercises should be actively carried out to enhance the strength of the surrounding muscles and joint mobility, and the diet should be strengthened to enhance the nutrition, and eat more calcium-containing foods such as milk, fish and shrimp to promote the growth of bone scabs. 2. Surgery: If there is no growth of bone scab 9 months after the fracture and no growth in 3 consecutive months of observation, then it is recognized as bone nonunion and needs surgery. Surgery is needed to remove the sclerotic lesion, ensure the opening of the bone marrow cavity, restore the blood supply of the fracture and promote the healing of the fracture site. In addition, local bone grafting can be used to induce bone cell growth at the fracture site to promote healing. Patients with sclerosis at the broken end of the ankle fracture are advised to actively cooperate with the doctor and choose appropriate measures under the doctor’s guidance.
