ARTICLE HIGHLIGHTS
Research background

A method regarding the appropriate assessment of fracture risk in long bone lesions affected by benign tumor is lacking.

Research motivation

We performed this study to determine an appropriate approach to assess the fracture risk in children with benign bone lesions of long bones.

Research objectives

The purpose of this study was to investigate the risk factors of pathological fracture and to propose a modified scoring system for quantitative analysis of the pathologic fracture risks.

Research methods

We retrospectively analyzed the histological diagnosis, anatomical site, radiographic appearance, severity of pain, and lesion size of 40 patients who had fractures through a benign bone lesion and 56 who had no fracture at our institution.

Research results

Through retrospective analysis of 96 patients using our proposed scoring system, we found the cutoff was 7 in consideration of the optimum combination of specificity and sensitivity. The overall accuracy was 76% and fracture probability was 30%. The receiver operator characteristic curve analysis demonstrates that the modified scoring system is good regarding accuracy and has a similar area under the curve with the Mirels scoring system.

Research conclusions

We set score of 7 as borderline. Lesion with a score > 7 is an indication for prophylactic stabilization because of high fracture risk, while lesion with a score < 7 is evaluated as low fracture risk without concern for prophylactic stabilization.

Research perspectives

In follow-up work, a prospective, multicenter, large-scale study will be conducted to validate and improve our proposed scoring system for assessment of the fracture risk in children with benign bone lesions of long bones.
