Clinical and radiographic evaluation of mechanical sufficiency of the operative treatment of pathological fractures in bone metastases.

UNLABELLED: Background. AIMS: Retrospective evaluation of mechanical sufficiency of applied surgical methods of bone metastases treatment according to authors' own scoring system. <br /> Material and methods. 60 patients with bone metastases treated operatively in our Ward during 1989-2002. Mean age of patients was 62,5 years old. There were 39 women and 21 men. In 48 cases (80%) there were possible to diagnose primary localization of the tumor. We could not reveal primary focus of the tumor in 10 cases (20%). Localizations of bone metastases are as follow: femur - 49 cases, humerus - 10 cases, tibia - 1 case. <br /> After local excision of metastatic tumor had been done the internal osteosynthesis and bone cement application was made in 45 cases, the internal osteosynthesis only was made in 7 cases, hip arthroplasty was made in 8 cases. Mean time of follow-up since surgical procedure was 8 months. Scoring system for radiographic and clinical evaluation of mechanical efficacy of operative fixation of pathologic fractures: grade I - good mechanical fixation, grade II - minimal loss of fixation, grade III - poor mechanical fixation, grade IV - relapse of pathological fracture. <br /> Results. We had poor results in 5%, because of the death of 3 patients. In 58 cases (97%) we had very good or good results - no pain, good function and independence in daily activities (grade I and II in scoring system of mechanical efficacy of pathologic fracture fixation). In remaining 2 patients (3%) there was loss of mechanically stabile fixation of pathological fracture. <br /> Conclusions. 1. Mechanical efficacy of the fixation of pathological fractures is good and lasting in 97% of cases. 2. Local complications rate was 2% and was due to mechanical unstabile fixation of pathological fracture.
