Conservative surgery for giant cell tumors of the sacrum. The role of cryosurgery as a supplement to curettage and partial excision

Abstract

Conservative surgery (curettage or partial excision) with adjunct of cryosurgery is our preferred technique for the treatment of GCT of the sacrum. Satisfactory local control could be obtained by close observation, second look biopsy and repeat cryosurgery. The chief advantages of this method include preservation of pelvic and spinal continuity, speed and ease of surgical procedure and less potential blood loss. We recommend it over more radical sacrectomy due to low morbidity and less resultant neurologic deficits.
