The objective of this study was to present a simple, convenient, and reliable technique for the application of liquid nitrogen and to evaluate the effectiveness of curettage and cryosurgery. Between 1992 and 2002, 24 patients who had benign aggressive and low-grade malignant bone tumors were treated by curettage and cryosurgery. While cryosurgery was applied by the 'direct pour' technique in the first seven patients, it was applied by the 'pressurized spraying' technique in the others. Functional results were graded according to Enneking. The mean follow-up was 47 (range 9-131) months. There were no local recurrences. Three patients who underwent the direct pour technique developed partial skin necrosis. The functional results were excellent in 14 patients, good in six, and fair in four. When compared with previous reports on cryosurgery and its application techniques, we detected no tumor recurrence or complications, including soft-tissue injury, infection, and late fracture with liquid nitrogen applied by the pressurized spraying technique.
