Objective: Through clinical observation and leather somatosensory evoked potentials technologies (DSEP), comparing percutaneous laser disc decompression (PLDD) and nuclear collagenase technique (CNL) treatment of lumbar disc herniation and features. Methods: Case inclusion and exclusion criteria specified. October 2001 - December 2002 period in respect of Jane, a diagnosis of L4 / 5 or L5/S1 disc herniation 56 cases, in accordance with the afternoon visiting time is divided into different groups and PLDD CNL group. In the X-ray, the use of non-vascular interventional treatment techniques, application-specific special devices, percutaneous disc and foraminal corresponding to the position of the disc and laser vaporization respectively collagen injections dissolving enzymes. All patients before treatment, after treatment, one week and three months after treatment for skin somatosensory evoked potentials (DSEP) measurement, recording latency and amplitude values. Applications Branch of the Chinese Medical Association orthopedic spine study group evaluation criteria, with \SPSS10. software for statistical analysis. Results: All patients were followed up to three this month, CNL group they lost, PLDD group a person lost to collect basic information on the remaining patients. 1. According to the Chinese Medical Association Orthopaedic Spine Study Group evaluation criteria, CNL group and excellent postoperative PLDD rates were 69% and 79%. Both methods excellent rate was no significant difference (P = 0.402). 2. CNL group of three incubation periods were (48.7 ± 1.9) ms, (49.0 ± 2.1) ms (45.3 ± 2.5) ms, amplitude change rate was (9.96 ± 3.45)%, (37.62 ± 11.53)% PLDD group three incubation periods were (49.4 ± 2.2) ms, (45.3 ± 2.3) ms, (41.6 ± 1.9) ms amplitude change rate was (28.7 ± 8.75)%, (56.01 ± 17.73)%. Two groups of patients postoperatively appear latency, amplitude prolonged improvement of neurological function. 3. After two hours, PLDD group latency and amplitude change rate CNL group with the same friends, the differences were statistically significant (P <0.05). Conclusion: PLDD with CNL belong to minimally invasive techniques, patient injury, quick recovery of function after surgery, the two methods is indeed effective, reliable, PLDD methods and methods of early CNL was no significant difference in efficacy. Application dermatome somatosensory evoked potentials technologies that can be judged by CNL PLDD technology and objective indicators of the efficacy of technology.
