Abstract

Purpose: To evaluate the longterm results of automated percutaneous lumbar discectomy vs endoscopic discectomy Method: Patients with lumbar disc disesase (n=114) were underwent automated percutaneous lumbar discectomy (APLD) between years 2004-2006. The ninty-four patients who have regular follow-ups included to the study. Success was defined as performance of daily activities without backpain. Re-operation at peroperative or postoperative period was accepted as failure. Kaplan- Meier survival statistical analyses was done. Patient satisfaction and pain reassessed by Oswestry disability index (ODI) and Visual Pain scales. Intervertebral disc space, disc degeneration (Modic) re-assessed by X-ray and MRI findings in the last follow-up, at year 2010. Results: The mean follow-up time was 42 months. The patients who had an open surgery immediate after APLD (n=14) and patients who had endoscopic discectomy (n=8) peroperatively at APLD were accepted as failure. According to ODI, pain scales and radiological findings, 22 patients accepted as failure at 4 years follow-up. Conclusion APLD relieved the pain by decompressing the high intradiscal pressure but it can lead the inefficient intervertebral suspension and faset joint wear. It is strongly possible that this mechanical failure can be responsible for long term failures. We concluded that vertebral functional unit should be evaluated instead of possible loosening tension effect of disc. If needed, the APLD surgery might be combined with interspinous or pedicular distraction d
