Abstract
Objective: The research aims to compare the therapeutic effect between improved system of micro-endoscopic discectomy (MED) and traditional discectomy for the treatment of lumbar stenosis. Methods: A retrospective study was carried out in two randomly allocated groups totaling 300 patients with lumbar stenosis, the improved MED group A and the conventional group B. All of them were examined by Xray, CT, MRI and proved to be lumbar stenosis. Intraoperative blood loss and hospital stay were analyzed. Results: The average of blood loss in group A: 83.10 ml ± 5.21 ml, while in group B, the blood loss were 150.13 ml ± 10.23 ml. And the average of hospital stay after operations in group A were 7.2 ± 1.1 days, group B 11.9 ± 1.4 days. There were significant differences between two groups (P<0.05). There were 5 cases suffering endorachis rupture in each of the two groups, which all healed after treatment. There were 4 cases suffering spine instability in group B after treatment of 4 years. And those patients were treated with cumber fusion jointed by GSS pedicle screw fixation. There were no other complications, such as operational mistakes, nerve root injury, cauda equina injury. There were no recurrent cases. According to the Nakai classification, the excellent and good rate has no significant differences between the two groups (P>0.05). Conclusion: The curative effects of both methods are satisfactory, but the improved system of MED has more advantages compared with traditional discectomy, which can be one of the ideal minimal invasive operations.
Highlights
Lumbar stenosis is a common and complicated disease
We aim to offer a better surgical solution for lumbar spinal stenosis
Comparing the methods of improved system of micro-endoscopic discectomy (MED) with traditional discectomy for lumbar stenosis, MED is a combination of traditional discectomy and endoscopic techniques
Summary
Traditional decompression surgery is well suggested, it can lead to spinal instability and scarring from hematology because of the destruction of the posterior spinal structures [1]. It can maintain the stability of spinal biomechanics on the premise of full decompression [2]. The MED (micro-endoscopic discectomy) was first applied to lumbar disc herniation by Smith and Foly in 1997 It is accepted by patients because it causes less pain and has the advantages of small incision, high-resolution [3]. We aim to offer a better surgical solution for lumbar spinal stenosis
