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


OBJECTIVE
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.
