Pathological fractures could be prevented if reliable methods of fracture risk assessment were available. A multi-center, prospective study was conducted to identify significant predictors of physicians' treatment plan for skeletal metastasis based on clinical fracture risk assessments and the proposed CT-based Rigidity Analysis (CTRA). Orthopaedic oncologists selected a treatment plan for 124 patients with 149 metastatic lesions based on Mirels method. Then, CTRA was performed and the results were provided to the physicians, who were asked to reassess their treatment plan. The pre- and post-CTRA treatment plans were compared to identify cases where the treatment plan was changed based on the CTRA report. Patients were followed for a 4 month period to establish the incidence of pathological fractures. Pain, lesion type and lesion size were significant predictors of the pre-CTRA plan. After providing the CTRA results, physicians changed their plan for 36 patients. CTRA results, pain and primary source of metastasis were significant predictors of the post-CTRA plan. Follow up of patients who did not undergo fixation resulted in 7 fractures; CTRA predicted these fractures with 100% sensitivity and 90% specificity, whereas the Mirels method was 71% sensitive and 50% specific. Lesion type and size and pain level influenced the physicians’ plans for management of metastatic lesions. Physicians’ treatment plans and fracture risk predictions were significantly influenced by the availability of CTRA results. Due to its high sensitivity and specificity. CTRA could potentially be used as a screening method for pathological fractures.
