Objective: To investigate the mechanism of expression and significance of vascular endothelial growth factor (VEGF) and p53 in degenerate intervertebral disc tissue.
Methods: Pathological sections collected from 156 patients with lumbar disc herniation after surgery were tested by immunohistochemistry method, for evaluation of the expression of VEGF and p53 in degenerate intervertebral disc tissue.
Results: 98 cases (62.8%) with vascular infiltration phenomenon are found, and positive rates of VEGF and p53 in degenerate intervertebral disc tissue are 73.42% (116/156) and 58.97% (92/156); co-expression rate is 53.2%(83/156); the expression rates of VEFG and p53 are significantly higher in the tissue with blood vessel infiltration than in the tissue without infiltration; there is a close relationship of VEGF with p53.
Conclusions: VEGF and p53 gene synergetic express in degenerate intervertebral disc tissue, working together in neovascularization and infiltration, and accelerating intervertebral disc tissue degeneration.

Gadolinium-Enhanced 3-Dimensional MRI for Diagnosis and Surgical Planning of Posterior Epidural Migration of Lumbar Disc Fragment: A Case Report.

Case: A 34-year-old man presented at our hospital with knee collapse. Magnetic resonance imaging (MRI) revealed posterior compression of the dural sac by a lumbar epidural lesion; however, a diagnosis could not be reached. Gadolinium (Gd)-enhanced 3-dimensional MRI (3D-MRI) clearly delineated the morphology, enabling us to make a preoperative diagnosis of posterior epidural migration of the lumbar disc fragment (PEMLDF).

The skeletal system, composed of bones, muscles, joints, ligaments, and tendons, serves as the foundation for maintaining human posture, mobility, and overall biomechanical functionality. However, with ageing, chronic overuse, and acute injuries, conditions such as osteoarthritis, intervertebral disc degeneration, muscle atrophy, and ligament or tendon tears have become increasingly prevalent and pose serious clinical challenges. These disorders not only result in pain, functional loss, and a marked reduction in patients' quality of life but also impose substantial social and economic burdens.

Background/context: Chronic low back pain (CLBP) is a significant US healthcare burden with millions of lumbar spine procedures annually. Diagnostic tests are essential to guide treatment but provocative discography (PD), the most common diagnostic procedure, is without robust evidence of its value. A non-invasive alternative using Magnetic Resonance Spectroscopy (MRS) offers a potential solution.

Background: One-hole split endoscopy (OSE) is a novel endoscopic technique that offers some advantages in spinal surgery. However, without a clear understanding of the safe zone for OSE, surgeons risk injuring nerve roots during the procedure. This study aimed to measure the safe distances among critical bone markers, the intervertebral space and nerve roots between 1-degree degenerative lumbar spondylolisthesis (DLS) and non-DLS at the L segment in patients via three-dimensional reconstruction and to compare the differences in relevant safety distances between the two groups.
