The thoracic spine is composed of 12 vertebra. It is continuous with the cervical spine above and the cervical spine below. The thoracic spine is connected bilaterally to the ribs. These connections add great stability to the thoracic spine. The spinal cord passes through the bony spinal canal and nerves emerge at the interface between each set of vertebra. Fractures of the spine are commonly secondarily to trauma. Weakened bones and bones involved with cancer can also fracture. Aside from causing structural changes in the spine, the spinal cord or nerves roots may me damaged or destroyed with these fractures. Thoracic spine fractures may also be associated with injuries to the heart, lungs and great vessels of the chest.
Causes of Thoracic Spine Fracture
Thoracic spine fractures commonly occur from trauma. Pathological fractures may occur with cancer or infections, where the bones have become involved. Osteoporosis, through decreased mineralization of the bone, leads to weakened bones which can also easily fracture.
Signs and Symptoms of Thoracic Spine Fracture
Pain and swelling occur at the site of the fracture. If the spinal cord or nerve roots have been injured, weakness or numbness of the chest, abdomen, legs, genitals and rectum may occur. Shortness of breath, coughing up blood and chest pain may develop. Instability of the spine can lead to deformity of the back.
