Objective: To explore operative effect of lumbar intervertebral disc herniation accompanying with lumbar instability.
Methods: Form June 2000 to June 2006, 46 patients of lumbar intervertebral disc herniation accompanying with lumbar instability were treated with decompression through posterior approach, diskectomy, spinal fusion and vertebral pedicle internal fixation. Including 33 males and 13 females,the age was from 37 to 68 years with an average of 48 years. The course of disease was from 4 months to 20 years with an average of 3.5 years. There were simple segment in 21 cases, double segments in 22 cases, three segments in 3 cases.
Results: All patients were followed up for 12-45 months with an average of 25 months. All cases got solid fusion and clinical symptom improved obviously. According to clinical standard to evaluation, 32 cases obtained excellent result, 8 good, 6 fair. The rate of excellent and good was 86.9%.
Conclusion: Diskectomy, spinal fusion and internal fixation can obtain satisfactory clinical effect for lumbar intervertebral disc herniation accompanying with lumbar instability.

Awake, endoscopic lumbar interbody spinal fusion: 10 years of experience with the first 400 cases.
J Neurosurg Spine

Objective: Awake, endoscopic spinal fusion has been utilized as an ultra-minimally invasive surgery technique to accomplish the goals of spinal fixation, fusion, and disc height restoration. While many techniques exist for this approach, this series represents a single institution's experience with a large cohort and the evolution of this method.
Methods: The medical records of a consecutive series of 400 patients treated over a 10-year period were retrospectively reviewed.
Morphometric and Morphological Study of Thoracic and Lumbar Intervertebral Discs in Guinea Pigs (Cavia porcellus).

This study investigates the gross morphological and morphometric characteristics of thoracic and lumbar intervertebral discs (IVDs) in guinea pigs, utilising micro-CT imaging and anatomical dissection. The findings reveal 13 thoracic and six lumbar IVDs were identified, with thoracic discs transitioning from rounded forms at T1-T3 to triangular and heart-shaped structures at T4-T13, while lumbar IVDs exhibited a consistently flattened heart shape. Morphometric analysis revealed statistically significant differences, with lumbar IVDs being larger in lateral and dorsoventral width, disc area, annulus fibrosus (AF) area and nucleus pulposus (NP) area, and ventral height compared to thoracic discs.

Background: There are differences in the extent of excision of articular processes, spinal processes and posterior ligamentum complexes (PLC) for posterior approach lumbar interbody fusion. Given that the biomechanical significance of these structures has been verified and that deterioration of the biomechanical environment is the main trigger for complications in both fused and adjacent motion segments, changes in decompression ranges may affect the potential risk of adjacent segmental disease (ASD) biomechanically; however, this topic has yet to be identified.
Methods: Posterior lumbar interbody fusion (PLIF) with different decompression strategies was simulated in a well-validated lumbosacral model.

Department of Neurosurgery Celal Bayar University, Faculty of Medicine Manisa Turkey.
Study Design: Prospective biochemical study of comparison of A Disintegrin and Metalloproteinase with Thrombospondin motifs-4 (ADAMTS-4) and A Disintegrin and Metalloproteinase with Thrombospondin motifs 5 (ADAMTS5) levels in preoperative and postoperative venous blood, as well as in disc tissue obtained during surgery, in patients undergoing surgery for intervertebral disc disease, with enzyme levels in venous blood from a control group.
Objective: To compare the levels of ADAMTS-4 and ADAMTS-5 between patients with degenerative intervertebral discs and a healthy control group, aiming to identify biomarkers associated with intervertebral disc degeneration.
Literature: Although numerous studies have investigated the relationship between ADAMTS-4 and ADAMTS-5 enzymes and degeneration in experimental rat models and human tissues, no study has correlated their serum levels with intervertebral disc degeneration.
Spinal cord gray matter atrophy is associated with disability in spinal muscular atrophy.

Department of Neurology, University Hospital Basel, University of Basel, Basel, Switzerland.
Background: With the approval of disease-modifying treatments for 5q-spinal muscular atrophy (SMA), there is an increasing need for biomarkers for disease course and therapeutic response monitoring. Radially sampled Averaged Magnetization Inversion Recovery Acquisitions (rAMIRA) MR-imaging enables spinal cord (SC) gray matter (GM) delineation and quantification in vivo. This study aims to assess SC GM atrophy in patients with 5q-SMA and its associations with clinical disability.
