EARLY COMPLICATIONS IN THE ORTHOPEDIC TREATMENT OF BONE METASTASES

Objective: To assess the early complications in the orthopedic treatment of metastatic bone lesions and the factors associated with these complications. Method: There were assessed, retrospectively, 64 patients that underwent surgical treatment for bone metastases, analyzing the complications that occurred in the pre-operative and early post- operative period and associating them with the tumor origin, type of procedure done, the need of blood reposition before the surgery, the need of new surgical procedures and the mortality due to the complications. Results: Early complications in the treatment were observed in 17 (26.6%) patients, of which six (35.2%) ended up dying due to these complications. Regarding the type, 15 (23.8%) cases were due to surgical complications, four (6.3%) clinical and three (4.7%) patients showed clinical and surgical complications. There was no significant difference in the frequency of complications or mortality when assessed the type of reconstruction or affected region. The tumors with a renal origin needed more blood reposition and showed a bigger frequency of complications. Conclusion: The complications occurred in 26.6%. The complications are not related to the kind of treatment performed or to the region affected. The renal origin tumors showed a higher risk of hemorrhage.
