[Application of three dimensional CT reconstruction in the diagnosis and treatment of bone and joint injury and spinal stenosis].
OBJECTIVE
To explore the application of three dimensional(3D) CT reconstruction(3D-CT-R) in spinal stenosis and injury of the bone and joint.


METHODS
Forty cases were examined with the X-ray film, CT scan and 3D-CT-R. To evaluate their diagnostic value, the images of the three methods were compared.


RESULTS
X-ray films could show a visible shift of fracture pieces, but we were sometimes incapable of diagnosing fractures accurately from X-ray and, therefore, we couldn't diagnose fractures located at a special position; the CT scan could show the fractured place with a better result, but it required that doctors should have enough clinic experience, and should be familiar with local anatomy to avoid possible misdiagnosis.


CONCLUSIONS
3D-CT-R could be used in formulating a particular treatment scheme, and is an ideal examination method.
