Abstract Background and Objectives Cryosurgery using liquid nitrogen is used as adjuvant treatment after intralesional resection of bone tumours to induce cell death. It is applied to enlarge the oncological margins of resection and to reduce the local recurrence rate. The objective of this study is to analyze the oncological and functional results. Methods We studied the oncological and functional results of curettage and cryosurgery in 123 patients with 130 tumors. There were 75 enchondromas and 55 chondrosarcomas grade 1. The minimal follow‐up period for all patients was 2 years (range 24–119 months). Results During follow‐up one local recurrence of an active enchondroma and one local recurrence of an aggressive enchondroma occurred. They were treated with curettage and cryosurgery again. Both patients were disease‐free at minimum of 3 years follow‐up. No local recurrences after treatment of chondrosarcoma grade 1 were seen. Functional scores, according to the MSTS scoring system, showed an average score of 28 points (94%) at 2 years follow‐up. Post‐operative fractures were seen in 18 patients (14%). Conclusions Curettage and cryosurgery for enchondroma and chondrosarcoma grade 1 has excellent oncological and functional results. The post‐operative management has been adjusted to reduce the number of fractures. J. Surg. Oncol. © 2008 Wiley‐Liss, Inc.
