Clinical Study of Ultrasound‐Guided Modified Percutaneous Endoscopic Interlaminar Discectomy Combined With Medical Chitosan in Lumbar 4–5 Disc Herniation Treatment

Orthopaedic Surgery, EarlyView.
Ultrasound‐guided PEID plus medical chitosan can effectively reduce postoperative pain and perioperative complications, demonstrating superior clinical efficacy. ABSTRACT Objective Percutaneous endoscopic lumbar discectomy (PELD) is a preferred minimally invasive surgery for lumbar disc herniation (LDH); however, postoperative recurrence, nerve root ...

Creation of an injectable in situ gelling native extracellular matrix for nucleus pulposus tissue engineering

, 2017
Background Context: Disc degeneration is the leading cause of low back pain and is often characterized by a loss of disc height, resulting from cleavage of chondroitin sulfate proteoglycans (CSPGs) present in the nucleus pulposus.

The Anterolateral Transpedicular Transverse Process Screw Technique: Surgical Techniques, Biomechanical study and Preliminary Outcomes

Orthopaedic Surgery, EarlyView.
This study designed a novel anterolateral screw placement technique and, based on this, developed a new anterolateral fixation method. Imaging, biomechanical, and short‐term efficacy analyses revealed that the Anterolateral Transpedicular Transverse Process Screw (ALTTS) technique achieves a high success rate for L5 vertebral fixation (pedicle width ...

The evolutionary importance of cell ratio between notochordal and nucleus pulposus cells: an experimental 3-D co-culture study [PDF]

, 2011
Notochordal cells and nucleus pulposus cells are co-existing in the intervertebral disc at various ratios among different mammalians. This fact rises the question about the interactions and the evolutionary relevance of this phenomenon.

Intervertebral Disc Degeneration and Regeneration: New Molecular Mechanisms and Therapeutics

Cells
The intervertebral disc (IVD) is a soft tissue that constitutes the spinal column together with the vertebrae, and consists of the central nucleus pulposus (gelatinous tissue) and the annulus fibrosus (rich in fibrous tissue) that surrounds the nucleus ...

Comparison of Adjacent Segment Degeneration After Nonrigid Fixation System and Posterior Lumbar Interbody Fusion for Single-Level Lumbar Disc Herniation: A New Method of MRI Analysis of Lumbar Nucleus Pulposus Volume

Journal of Investigative Surgery, 2018
Purpose: To evaluate the influence of a nonrigid fixation system and posterior lumbar interbody fusion on adjacent intervertebral disc degeneration by using MRI analysis of lumbar nucleus pulposus volume for single-level lumbar disc herniation. Materials

From senescence and inflammaging to systemic comorbidities: Drivers of aging‐associated periodontitis

Periodontology 2000, EarlyView.
Abstract Background Aging is accompanied by a chronic low‐grade inflammatory process, known as inflammaging, as well as immunosenescence, an age‐related decline and dysregulation of immune function, and cellular senescence, a process in which cells enter a state of irreversible growth arrest while actively releasing pro‐inflammatory factors.

MANAJEMEN NYERI PASIEN RAWAT JALAN PADA KASUS HERNIA NUKLEUS PULPOSUS MELALUI CORE STABILITY

Jurnal Vokasi Indonesia, 2014
Herniated nucleus pulposus (HNP) is a situation where the annulus fibrosus along nucleus pulposus protruding into the spinal canal. HNP patients often complain of back pain radiating to the lower limbs, especially when bending activity.
