LONG-TERM RESULTS OF CRYOSURGICAL TREATMENT OF BONE TUMOR-LIKE LESIONS

In order to optimize surgical intervention the results of surgical treatment of 324 patients with tumor-like lesions of bone were studied. Study group comprised 211 people who were executed cryosurgical intervention. In 113 patients (control group) a similar intervention was performed, but without the cryosurgical exposure. In the study group the subjective and objective assessment of outcome of treatment was significantly different (at χ² = 9,5 p <0,01). It is explained by the variability of complications after the cryosurgical procedures. It was found that the ratio of types of surgical procedures carried out in this pathology, has changed over time. The number of intralocal and regional resections have increased while the number of segmental resections have decreased (at t = 2,7 p <0,05). The introduction bone cryosurgical procedures in clinical practice allowed to decrease the number of segmental resections from 27.6% to 4.8% and to increase the range of intralocal resections from 25.8% to 77.7%. The recurrence rate was 2.4% in the main group and 7.1% - in the comparison group.
