Abstract:

BACKGROUND: Currently, one of common methods is discectomy, nerve root decompression and fusion rigid fixation from the midline approach for disc herniation which is inefficient by conservative treatments. Thus, it is causing degeneration and limiting lumbar physiological activity of adjacent segments. The treatment of non-fusion lumbar disc herniation with the traditional posterior midline incision approach has some disadvantages such as big incision, wide peeling, and back muscle denervation.

OBJECTIVE: To observe therapeutic effects of dynamic stabilization system through Wiltse approach on lumbar disc herniation, and to compare the outcomes with traditional posterior approach.
METHODS: A total of 46 patients, who had undergone discectomy and internal fixation using dynamic stabilization systems for lumbar disc herniation at the Renmin Hospital of Wuhan University from January 2011 to January 2013, were enrolled in this study. The operation was performed through the traditional posterior approach in 25 patients and Wiltse approach in 21 patients.

RESULTS AND CONCLUSION: All 46 patients were followed up for 7 to 31 months (averagely, 13.8±2.4 months). The length of incision, intraoperative blood loss, and postoperative drainage amount were less in the Wiltse approach group than in the traditional posterior approach group (P < 0.05). No significant difference in visual analog scale scores and operative time was detected between the two groups at 1 week and 6 months after fixation (P > 0.05). Radiographs revealed that the position of implants was good in all patients, no loosing or breakage. These data verified that the early effect of dynamic stabilization system through Wiltse approach for lumbar disc herniation is similar to that of traditional posterior approach.
