Abstract—The lifespan can be increased in a positive mode by initial diagnosis of osteoporosis. Analysis of trabecular properties on digital hip radiographs could be useful in identifying the subjects with low bone mineral density (BMD) or osteoporosis. Early detection of fracture risk is important for initiating treatment and improving outcomes from both physiologic and pathologic causes of bone loss. So, the aim of the present study was to test the potentiality of the discrete wavelet transform based qualitative trabecular bone analysis method for the assessment of osteoporosis using simple radiographs. Our study was performed on 20 post-menopausal women without osteoporotic fractures and 21 healthy pre-menopausal women. For all subjects radiographs and bone mineral density measurements were obtained. The energy computed from trabecular pattern of normal bone by trabecular enhanced radiographic samples appeared to be higher than the energy from samples of the osteopenia and osteoporosis in greater-trochanter and neck regions. Hence forth, our results suggest that, the plain radiographs might be used instead of BMD measurements for the screening of osteoporosis and its associated fracture risk assessment.
