What other kinds of spinal curvature are there beside scoliosis?

See below. The normal curves in the spine are called lordosis and kyphosis. In the neck and low back, we typically have a lordosis and in the thoracic spine which is the middle part, we have a kyphosis. It is possible to have extremes of both lordosis and kyphosis which are not normal for example, women or men with severe osteoporosis may have an excessive kyphosis in the thoracic spine.
Several. Other types include a kyphosis which is an increase forward bend of the spine or a lordosis which is an increase in the backward bend of the spine. These can be found in conjunction with one another and with scoliosis.
