Abstract:
Objective To report the surgical technique and preliminary clinical results of bilateral decompression under microscope via unilateral approach for the treatment of lumbar stenosis. Methods Sixteen eases of lumbar stenosis were treated in our institute. For the surgical treatment, only one side paraspinous muscle was dissected. The upper and lower margins of the adjacent laminae were drilled, and the underlying ligament flavum was exposed. By changing the direction of the microscopy, the base of the spinous process and the internal side of the contralateral laminae were also drilled off till the lateral recess. Finally, decompression of the spinal canal was achieved by removing the ligament llavum. Results Follow-up ranged from 6 to 47 months. Intermittent claudication was totally relieved in 14 out of 16 cases, and markedly relieved in 2 cases. Back pain was relieved totally in 6 cases, marked improved in 8 cases, not change in 2 cases. Pain was significantly relieved in all 5 cases with sciatica, among them, diseetomy had to be performed in 3 cases. During follow-up, there was no symptom recurrence, and dynamic X ray did not show lumbar in-stability. Conclusion Bilateral decompression under microscope via unilateral approach for the treatment of lumbar stenosis is minimally invasive surgery, the effect of the operation is good. The technique has little in-fluence on spinal stability.
