Their demographic data, location site, area of bone defect, and pertinent operative details were recorded. The reconstruction modality of allografts was elaborated on. In the follow-up, radiographic images were utilized to determine bone union, and the Musculoskeletal Tumor Society score was used to evaluate postoperative limb function.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of seven patients were included, including three males and four females with an average age of 16.6\u2009\u00b1\u20096.5 years. Among them, three cases of tumors occurred in the humerus and four cases occurred in the femur. The average follow-up time was 11.3\u2009\u00b1\u20093.0 months.

No complications such as infection, nonunion, and allograft bone fracture were found during the follow-up period.
