Abstract:

Purpose: To Analyze the safety and efficacy of percutaneous radiofrequency and cryotherapy on benign tumors of the locomotor system, in addition to assessing its complications to establish some recommendations for use.
Material and methods: Retrospective study in which 41 patients treated between 2000 and 2021 were collected, with the following inclusion criteria: diagnosis of benign tumors (clinical-radiological and/or pathological diagnosis), who were treated percutaneously guided by CT with radiofrequency or cryotherapy. We analyzed demographic and clinical data before and after the procedure, tumor location, response to treatment, local and orthopedic complications, and local recurrence. Statistical analyzes were performed with IBM SPSS Statistics 25.
Results: We studied 41 cases with a mean age of presentation of 36.9 years (11-71), and a mean follow-up of 14 months (3-36). Histologically confirmed: 12 osteoid osteomas, 4 chondroblastomas, 3 osteoblastomas and one phosphaturic mesenchymal tumor, including 21 osteoid osteomas without histological confirmation despite biopsy.
We performed radiofrequency in 34 patients and cryotherapy in 7. Relapse of symptoms occurred in 10 patients. There have been no local or orthopedic complications derived from thermal therapies for the treatment of tumors
Conclusion: CT-guided radiofrequiency is a minimally invasive, safe, and highly effective treatment for these tumors. In certain anatomical locations it could be subject to joint or vascular-nervous complications. In this sense, cryotherapy allows direct control of the volume of treatment, defining its limits more accurately, to avoid said complications. Therefore, both techniques are safe, effective, and interchangeable in the treatment of this pathology. We recommend individual planning for each case.
