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.

Biomed Res Int 2021 5;2021:6653579. Epub 2021 Apr 5.

Department of Orthopaedic Surgery, The First Affiliated Hospital of Soochow University, Suzhou, Jiangsu 215006, China.

Considering the increasingly incidence rate of lower extremity arterial occlusive disease and difficult to distinguish from lumbar disc herniation, it is very necessary to exclude lower extremity arterial occlusive disease resulting in lower limb symptoms from lumbar disc herniation. More importantly, who have a higher risk of combining with lower extremity arterial occlusive disease and misdiagnosed as lumbar disc herniation? Why those patients are easy to be misdiagnosed as lumbar disc herniation? It is worth analyzing and discussing. The risk factors including age, gender, the medical history of high blood pressure, diabetes, smoking and coronary, pulse pressure, lumbar disc herniation segment and type, ankle-brachial index, and straight leg raising test were observed.
