[Thoracolumbar injuries: pathomorphology of and a new classification].

OBJECTIVE

To introduce a new classification of thoracolumbar injuries.

METHODS

Three modes were used to classify the injuries according to the mechanisms of injuries: Type A, flexion-compression fractures; Type B, vertical compression fractures; Type C, distraction injuries. Two groups were used to distinguish the fractures in one type according to the pathomorphological differences and the clinical incidence: Group A, with a more clinical incidence, and Group B, with a less clinical incidence. Three subgroups were used to divide the injuries in one group in consideration of the severity of the fracture instability and the fracture displacement: fracture, subluxation, and dislocation.

RESULTS

A new classification of thoracolumbar fractures was established.

CONCLUSION

The new classification is more systemic and more convenient.
