Left-sided partial laminectomy L4-L5 (laminotomy) and right-sided multilevel laminectomy L3, L4, L5, and S1. In this illustration (Joseph A. Epstein M.D., Copyright Nancy E. Epstein M.D.) on the left side of the spinal canal at the L4-L5 level, part of the lamina above of L4 and below of L5 has been removed (e.g., laminotomy). On the right side, a multilevel laminectomy of the L3, L4, L5, and S1 levels has been completed

Background
The lumbar spine includes 5 lumbar vertebral bodies, L1, L2, L3, L4, and L5. At each level, there is a disc space defined by the two bones (vertebral bodies) in the back; for example, there is a disc space at the L5-S1 level etc. The normal front to back (anterior to posterior or AP diameter) measurement of the spinal canal is typically...

Background:
Burst fractures of the lumbar vertebrae and laminar fractures associated with dural tears and entrapment of neural elements have been reported in the past as a relatively rare occurrence. To the best of our knowledge, there is no consensus on the approach to repairing these types of fractures. The objective of this study is to describe...

Study Design Prospective clinical study. Purpose To investigate the effect of percutaneous transforaminal endoscopic surgery (PTES) for lateral recess stenosis (LRS)(LRS) in elderly patients and to assess patients’ health-related quality of life (HRQoL). Overview of Literature PTES is an increasingly used surgical approach, primarily employed for lumbar disc herniation treatment. However, indications for PTES have been increasing in recent years. PTES has been recommended as a beneficial alternative to open decompression surgery in specific LRS cases; PTES is termed as percutaneous endoscopic ventral facetectomy (PEVF) in such cases. Methods In total, 65 elderly patients with LRS were prospectively studied. Patients presented severe comorbidities (coronary insufficiency, heart failure, diabetes mellitus, and respiratory failure); thus, general anesthesia administration would potentially cause considerable hazards. All the patients underwent successful PEVF in 2015–2016. The patients were assessed preoperatively and at 6 weeks; 3, 6, and 12 months; and 2 years postoperatively. Patients’ objective assessment was conducted according to specific clinical scales; the Visual Analog Scale (VAS) was separately used for leg and low-back pain (VAS-LP and VAS-BP, respectively), whereas the Short Form 36 Health Survey Questionnaire was used for the HRQoL evaluation. Results All studied parameters presented maximal improvement at 6 weeks postoperatively, with less enhancement at 3 and 6 months with subsequent stabilization. Statistical significance was found in all follow-up intervals for all parameters (p
