Detection of vertebral fractures.
Despite the importance of vertebral compression fractures, there is much that remains uncertain. There is no "gold standard" for the definition which has led to epidemiologic and study differences. Height loss is a way to suspect vertebral fractures but it has its own issues. There are multiple radiographic systems for defining vertebral fractures, both prevalent and incident; risk factors for prevalent fractures have already been delineated. Recent studies have elucidated the risk factors for incident vertebral fractures including age, low weight, late menarche, lower bone mineral density, history of vertebral and nonvertebral fractures, smoking, and use of a walking aid. Fan beam densitometers have had improving ability to image the spine, a procedure now known as vertebral fracture assessment (VFA). Recently (in the United States) a CPT code and reimbursement was established. Yet, many vertebral fractures go undiagnosed, diagnosed but unreported, or reported but not utilized in patient care. Because of this, the International Osteoporosis Foundation developed a Vertebral Fracture Initiative for radiologists and the International Society for Clinical Densitometry began a VFA course. Both teaching programs use the semi-quantitative assessment of Genant to aid the radiologists and clinicians in detecting vertebral fractures.
