<p><b>OBJECTIVE</b>To study the imaging findings outcome of the percutaneous laser disc decompression (PLDD) and evaluate the middle-term safety and efficacy of PLDD.</p><p><b>METHODS</b>The imaging data of 22 cases suffered cervical spondylosis or lumbar spondylosis and treated by PLDD more than 3 years were retrospectively reviewed. To observe the intervertebral space of the invasive disc and the intervertebral disc hernia before and after the operation on the lateral projection of X-ray and the axial view of the MRI. To make a statistical analysis of the data.</p><p><b>RESULTS</b>There was no obvious change of disc height involving the anterior disc height, the intermediate disc height and the posterior disc height after the PLDD at the final follow-up (P > 0.05). At last time follow-up, the Sagittal Index (SI) are 0.10 - 0.54 and 0.06 - 0.39 before and after the PLDD in the treatment of cervical vertebra. The statistical difference were significant (P < 0.05). In lumbar vertebra, the SI is 0 - 0.71 and 0 - 0.48 disc before and after the PLDD. The statistical difference were very significant (P < 0.01).</p><p><b>CONCLUSIONS</b>The PLDD will not destroy the intervertebral space of the cervical and lumbar vertebra obviously; moreover, it can effectively reduce the disk hernia. The PLDD is a safe and effective Mini-invasive surgery for cervical vertebra and lumbar vertebra diseases.</p>

<p><b>OBJECTIVE</b>To explore the mechanism and feasibility of the supinator syndrome evoked embitterment test from anatomy and clinic.</p><p><b>METHODS</b>25 cases of The supinator syndrome were reviewed. 18 of them were male and 7 were female. Drop finger deformation were apparent in 25 cases and The supinator syndrome evoked embitterment test was positive for All patients. Operative neurolysis was done in 8 cases, conservation treatment 17 cases; 92 cadaver upper extremities were dissected for a study the relationship between supinator tunnel and posterior interosseous nerve.</p><p><b>RESULTS</b>22 cases had been followed up for an average of 9 months. 16 cases had a full recovery and 6 cases, a partial recovery. the anatomical study shows that The posterior interosseous nerve was compressed by Forhse arcade and the distal border of the supinator muscle during passive pronation forearm.</p><p><b>CONCLUSION</b>The supinator syndrome evoked embitterment test was a new test for the diagnosis of supinator syndrome, it was found to be more sensitive and specific than the others test.</p>
