Hunchback in the elderly should be considered to be caused by osteoporotic fractures and idiopathic kyphosis, as follows: 1. osteoporotic fractures: when age increases, bone loss will gradually accelerate, which will very easily cause osteoporotic fractures of the lumbar and thoracic vertebrae, and when osteoporotic fractures of the thoracic and lumbar vertebrae occur in elderly patients, the height of the anterior column will be lost, which will gradually form a hunchback shape; 2. In addition, idiopathic kyphosis: originally, kyphotic hunchback deformity may have occurred gradually in young age, and in old age, this hunchback deformity will be more serious due to osteoporosis and will be more obvious in appearance.
