Internal fixation with bone cement in reconstruction of bone defects due to bone metaseses.
Background. Retrospective evaluation of surgical technique, clinical and radiological results and mechanical sufficiency internal fixation with bone cement in treatment of bone defect due to metastatic lesions. Material and methods. 66 patients treated operatively due to pathologic fractures becuase of the bone metastases. Mean age of the patients was 65,5 y. o. There were 40 women and 26 men. In 53 cases (80%) origin of primary tumor was known. Localisation secondary tumors was as follow: femur - 52 cases, humerus - 13 cases and tibia - 1 case. Bone defects after curettage of metastasis were recunstrucated by bone cement and fixations were made by plate technique - 54 cases or intramedullary nail techique - 12 cases. Evaluation of the mechanical suffifciency of applicated recunstuction techniques in treatment of bone metastatic lesions was made accornig to athors' own scale: grade I - good stabilisation, grade II - fair destabilisation, grade III - advanced destabilisation and grade IV - complete destabilisation. Results. There were 2 deaths in early postoperative period (3%). Mean survial time after surgery was 13 months. In 64 cases excellent or good results were achived: good mechanical fixation and no pain. In left 2 cases partial and complete destabilisation of fixation occurred. Conclusions. Mechanical sufficiency of reconstruction techniques in metastatic bone lesions was good in study group. Incidence of local and systemic complications in study group was 3-time higher than in normal trauma fracture population, because of more sever general health status of patients with advaced neoplastic disease.
