Paper Abstract

Microfractures in bone, secondary to repetitive stress, particularly in the lower extremities, are an important problem for military recruits and for athletes. They also may occur in those with brittle bones, such as the elderly, or in patients taking bisphosphonates for osteoporosis. Microfractures can be early predictors of major bone fracture and may be as important as changes in bone density in predicting where and how likely a major fracture will occur. Unlike major bone fractures, microfractures can be difficult to detect by conventional methods. We explored a second NIR spectral window from 1,100 nm to 1,350 nm, and a third spectral window from 1,600 nm to 1,870 nm to image microfractures through tissue media. Due to a reduction in scattering at longer NIR wavelengths, employment of the second and third NIR windows may allow for deeper penetration into tissue and higher contrast images of microfractures underneath the skin.
