<p><b>OBJECTIVE</b>To explore the clinical effects of transforaminal endoscopic spine system in surgical revision of lumbar vertebrae.</p><p><b>METHODS</b>From January 2012 to October 2013,14 patients who needed reoperations of lumbar vertebrae were treated using transforaminal endoscopic spine system (TESSYS). There were 8 males and 6 males, aged from 27 to 84 years old with an average of (50.4 ± 18.9) years. Visual analogue scale (VAS) and Japanese Orthopaedic Association Scores (JOA) were compared before and after surgical revision. Macnab standard was used to assess the clinical effect.</p><p><b>RESULTS</b>All the patients were followed up from 6 to 27 months with the mean of 18 months. Preoperative VAS score was 6.79 ± 1.31, and in a week,3 months and 6 months after operation were 2.50 ± 1.29, 2.21 ± 1.53, 1.64 ± 1.08, respectively, which were all much lower (P < 0.01) than preoperative score. Preoperative JOA score was 12.43 ± 1.95, and the above corresponding postoperative JOA scores were 21.50 ± 3.78, 21.93 ± 4.55, 23.36 ± 4.33, respectively, which were all much higher than preoperative score (P < 0.01). According to the modified Macnab criteria, 5 patients got an excellent results, 7 good, 1 fair and 1 poor. The nerve root injury of L5 occurred in 1 case during paracentesis and no other complications were found.</p><p><b>CONCLUSION</b>Selecting the appropriate indications using TESSYS in surgical revision of lumbar vertebrae can successfully avoid the operation scar, reduce the surgical complications and obtain satisfactory clinical outcomes.</p>
