We aimed to investigate the feasibility of adjuvant FNEC–assisted cryoablation in different bone cavity types by assessing the perioperative complication rates.  \nMethods: The medical charts of patients who received intraoperative adjuvant cryoablation using semisolid FNEC for bone tumors from December 2013 to January 2018 were reviewed. The bone cavities were categorized into three types according to liquid spill potential (type 1, able to hold liquid without limb manipulation; type 2, required extensive limb manipulation to retain liquid; type 3, unable to retain liquid) . The overall complication rate and the complication rates stratified by bone cavity type were determined. Results: Among the 76 patients, 30.3%, 57.9%, and 11.8% had type 1, 2, and 3 bone cavities, respectively. The mean follow-up time for perioperative complications was 43.5 ± 24.1 days. Five patients experienced complications, including two cases of skin damage, two cases of skin infection, and one case of fracture, yielding an overall perioperative complication rate of 6.4% . All cases of skin damage and skin infection were superficial and manageable by oral antibiotics. The patient with a pathologic fracture recovered well after being treated with open reduction and plate fixation. No neuropraxia was noted within the first few days postsurgery in any patient. The complication rates in type 1, 2, and 3 bone cavities were 13%, 4.6%, and 0%, respectively.  \nConclusion: All bone cavity types had a low incidence of perioperative complications after treatment with adjuvant FNEC–assisted cryoablation. Semisolid FNEC–assisted cryoablation is a feasible alternative to overcome the liquid spill potential in bone cavities resulting from tumor resection and intralesional curettage.  \nKeywords: Bone neoplasms; Cryosurgery; Ethanol; Freezing  \n1. INTRODUCTION  \nThe technique of intralesional curettage combined with adjuvant cryoablation has been used to control local recurrence and to treat aggressive benign bone tumors, low-grade malignant bone tumors, and metastatic bone tumors. Studies have shown that extended curettage alone has a lower complication rate and better functional outcomes than does wide resection for  \n* Address correspondence.
