Chronic obstructive pulmonary disease (COPD) is caused by significant exposure to noxious particles and gases, most often tobacco smoking but also exposure to air pollution. It is characterized by chronic airflow limitation that is caused by a mixture of small airways disease (e.g. obstructive bronchiolitis) and parenchymal destruction (emphysema). Although COPD is primarily a pulmonary disease, there are significant comorbidities and extrapulmonary effects, such as cardiovascular disease, diabetes, muscle wasting, and osteoporosis. The reported prevalence of vertebral fractures (VFs) is high among patients with COPD (9-79%) and we have recently shown that incident VF risk is high in COPD patients and (former) smokers without COPD with one or more prevalent VFs. Hyperkyphosis, an excessive increase in thoracic spinal curvature, is a common condition estimated to affect about 20-40% of the older population. However, since normal kyphosis is increasing with age, cutoff values defining hyperkyphosis are lacking. Although presence of VFs is often reported to be the main cause of increased kyphosis, more than half of the hyperkyphotic patients do not have VFs. Other possible causes can be Scheuermann’s disease, intervertebral disk degeneration, and muscle weakness.
