Abstract:
Purpose To investigate the diagnostic value of high-resolution CT reconstruction techniques on the same slice in hypertrophy of transverse process of the fifth lumbar vertebra (HTPL5V), and to provide a basis for clinical diagnosis and treatment. Materials and Methods Twenty-two cases of clinically diagnosed HTPL5V and 20 normal adults were examined with GE LightSpeed 16-slice spiral CT (36 cases) and Philips iCT 256-slice (6 cases). L5 transverse process and the fifth lumber nerve were reconstructed and observed on the workstations. Results In 22 cases of HTPL5V, there were 26 pseudarthrosis formation and 2 sides with L5 transverse process touching the sacral ala. In 28 sides the iffth lumber nerve traveled through false foramina of the HTPL5V including 6 cases of bilateral compression and 16 cases of unilateral compression. In 21 cases, the nerve was compressed by hyperosteogeny on 27 sides (96.4%) and 1 side due to stenosis (3.6%). On 25 sides (89.3%) the compressed nerves were curved in shaper. There was bulging and/or herniated lumbar disc on 9 sides in 7 cases (32.1%). Conclusion High-resolution CT reconstruction techniques can demonstrate the iffth lumbar nerve of HTPL5V and provide evidence for clinical diagnosis and treatment.
