Percutaneous Endoscopic Lumbar Discectomy for Lumbar Disc Herniation Using an Endoscopic Staining: A Technical Note.

Orthop Surg 2021 May 4. Epub 2021 May 4.

Department of Spine Surgery, the 1st Affiliated Hospital of Guangzhou University of Chinese Medicine, Guangzhou, China.

Symptomatic lumbar disc herniation (LDH) is widely treated using percutaneous endoscopic lumbar discectomy (PELD). In the present PELD surgery, performing decompression under endoscope still takes a long time to explore the rupture site of annulus fibrosus, resulting in prolonged operation time and over-invasion of the undegenerated annulus fibrosus. A wide range of intraoperative exploration also induces an iatrogenic injury of the normal annulus fibrosus, even aggravating intervertebral disc degeneration, which may lead to early postoperative recurrence in severe case.

The role of altered glycosylation in human nucleus pulposus cells in inflammation and degeneration.

Eur Cell Mater 2021 Mar 28;41:401-420. Epub 2021 Mar 28.

CÚRAM, SFI Research Centre for Medical Devices, National University of Ireland, Galway,

Intervertebral disc (IVD) degeneration causes low-back pain through disc compression, prolapse and herniation. Inflammation of the IVD and subsequent degeneration produce altered glycosylation profiles in several animal models of IVD injury and ageing, although the function of this altered glycosylation pattern in a human is unknown. Altered N-glycome, specifically sialylated and fucosylated N-glycosylation motif expression, might play a role in inflammation and disease progression. Read More
