How to begin unilateral biportal endoscopy (UBE) for segmental lumbar degenerative disease: a step-by-step guide to perfect patient positioning and surgical approach, avoiding common pitfalls.

This document, published in the Neurosurgical Review, provides a detailed description of the surgical technique known as "unilateral biportal endoscopy" (UBE) for the treatment of spinal disorders. The UBE technique involves the use of two small incisions to access the epidural and foraminal areas of the spine, allowing for a magnified view and precise surgical maneuvers. The document outlines the step-by-step process of the surgery, including the use of various instruments and techniques for exposure, laminectomy, flavectomy, hemostasis, and closure. The authors emphasize the benefits of the UBE technique, such as reduced muscle injury, shorter hospital stays, and improved patient recovery. They also provide specific indications and technical variations for different types of spinal hernias and cysts. Overall, this document serves as a comprehensive guide for spine surgeons interested in learning and implementing the UBE technique. [Extracted from the article]
