A Comparison Between Biportal and Uniportal Endoscopic Lumbar Discectomy

Endoscopic Lumbar Discectomy: A Comparative Study Between Uniportal and Biportal Endocopic Techniques on Clinical and Surgical Outcomes

This study aims to provide a detailed comparison between different methods of lumbar discectomy by the use of different types of spine endoscopy to evaluate the benefits and drawbacks of each type

The aim of this study is to compare between uniportal and biportal endoscopic techniques in patients with lumbar disc herniation in terms of efficacy, safety, and learning curve of endoscopic spine surgery .The research will focus on clinical outcomes, functional recovery, complication rates, patient satisfaction and surgical proficiency in different endoscopic spine surgery techniques, including uniportal and biportal approaches assessing their relative advantages and limitations.
