“…Surgical resection and curettage are still considered the main treatment for these tumors; however, recurrence rate ranges from 10 to 35% in the case of chondroblastoma and this type of surgical procedure can cause physical and emotional trauma for pediatric patients [ 3 ]. Percutaneous ablation represents a safe and effective minimally invasive alternative for treatment of benign musculoskeletal tumors in children [ 4 ]. Radiofrequency ablation (RFA) is the most commonly used thermal ablation method and has shown positive and long-standing effects for the local control of osteoblastoma and chondroblastoma [ 5 ].…”

Background To review the safety and efficacy of percutaneous cryoablation for the treatment of chondroblastoma and osteoblastoma in the pediatric and adolescent population. Materials and methods A retrospective review from 2016 to 2020 was performed to evaluate clinical and imaging response to percutaneous cryoablation in 11 symptomatic patients with diagnosis of chondroblastoma and osteoblastoma treated from two pediatric hospitals with at least 12-month follow-up. Technical success (correct needle placement and potential full coverage of the tumor with the planned ablation zone) and clinical success (relief of the symptoms) were evaluated. The primary objective was to alleviate pain related to the lesion(s). Immediate and late complications were recorded. Patients were followed in clinic and with imaging studies such as MRI or CT for a minimum of 6 months. Results A total of 11 patients were included (mean 14 years, age range 9–17; male n = 8). Diagnoses were osteoblastoma (n = 4) and chondroblastoma (n = 7). Locations were proximal humerus (n = 1), femur condyle (n = 1), and proximal femur (n = 1) tibia (n = 3), acetabulum (n = 3), thoracic vertebra (n = 1) and lumbar vertebra (n = 1). Cryoablation was technically successful in all patients. Clinical success (cessation of pain) was achieved in all patients. No signs of recurrence were observed on imaging follow-up in any of the patients. One of the patients developed periprocedural right L2–L3 transient radiculopathy as major immediate complication. Conclusions Percutaneous image-guided cryoablation can be considered potentially safe and effective treatment for chondroblastoma and osteoblastoma in children and adolescents.

“…Other thermal percutaneous ablation treatments, such as cryoablation, have been used to treat benign bone tumors [ 4 ]. Despite the common use of cryoablation to manage painful bone metastases, its use to treat benign, locally aggressive musculoskeletal lesions remains limited.…”
