Percutaneous injection of calcium phosphate composite in pediatric unicameral bone cysts: a minimum 5-year follow-up study

Background Unicameral bone cyst (UBC) is a common lesion in skeletally immature patients. Multiple treatments are proposed as curettage and autologous bone graft, percutaneous local corticoids injections, decompression with internal fixation, and injection of bioresorbable cement. Decompression, curettage, and percutaneous bioresorbable cement injection showed interesting results, but until now, no long-term follow-up was reported in pediatric patients with UBC.
