The application of Ilizarov's "bone segment transport" method in the treatment of tumors and tumor-like changes in bone.

Background. The authors present their own experience in the application of the "bone segment transport" method developed by Ilizarov for filling post-resection bone deficits in the treatment of neoplastic tumors in long bones. Material and method. Our research involved 9 patients: 2 female patients with an average age of 14.5, and 7 male patients with an average age of 16.7. The follow-up time ranged from 2 to 8 years (average 3.4). Of these patients, 5 were treated for giant-cell tumors with varying degrees of malignancy. Among the remaining patients the bone transport method was used in 2 cases of osteogenic sarcoma, 1 case of chondrosarcoma, and 1 case of aneurismatic cyst. The choice of surgical treatment method was made on the basis of the surgical systems of evaluation and classification of tumors in the locomotor apparatus provided by the Musculoskeletal Tumor Society and described by Enneking. Results. The authors discuss the method and the results using the example of three cases: an osteogenic sarcoma, a giant-cell tumor, and an aneurismatic cyst. The outcome for bone tumors treated with the "bone segment transport" method are satisfactory. Conclusions. In our material there were no tumor relapses after the combined treatment program was completed. In addition, the preservation of the limb provides psychological comfort for the patient, for whom the potential loss of the limb is a source of stress, often undermining faith in the good effects of treatment.
