M96.2: Postradiation kyphosis

Your spine has curved too much after you were given radiation treatment.

The spine consists of several sections. The cervical spine begins below the head. The cervical spine is very mobile. Below that is the thoracic spine. The ribs are attached to the thoracic spine. Below the thoracic spine is the lumbar spine. The lumbar spine is also very mobile and it bears a large part of the body’s weight. After the lumbar spine, the sacrum and coccyx join.

If you look at your spine from the side, you can see that your spine is not quite straight. Your spine is alternately curving inwards and outwards. Your cervical spine and lumbar spine curve inwards. Your thoracic spine and sacrum curve outwards.

Your spine is curved too far outwards.

If a child has been given radiation treatment to their chest, for example, the back muscles then sometimes fail to develop properly. The spine can then curve outwards too much. The spine sometimes also curves after a vertebra is broken.

If the spine is too curved, there may sometimes be no problems. But one may have back pain, for example.
