Abnormal Cervical Facet Orientation and Congenital Stenosis: Case Reports and Biomechanical Implications—Illustrative Cases

Clinical Case Reports, Volume 14, Issue 7, July 2026.
ABSTRACT In patients with congenital cervical stenosis, the addition of abnormal cervical facet orientation (horizontal or hypoplastic joints) may predispose to segmental instability, subluxation, and canal compromise. Full assessment of facet anatomy is essential pre‐operatively, as selected patients (e.g., those with demonstrable subluxation, widened

Serum Periostin Level Reflects Progression of Ossification of the Posterior Longitudinal Ligament

JBJS Open Access, 2022
Background:. Ossification of the posterior longitudinal ligament (OPLL), characterized by ectopic new bone formation in the spinal ligament, causes neurological impairment due to narrowing of the spinal canal.

Comparative Efficacy of Posterior Versus Lateral Endoscopic Approaches in the Management of Complex Lumbar Disc Herniation: A Retrospective Cohort Study

Orthopaedic Surgery, Volume 18, Issue 4, Page 695-709, April 2026.
PEID and PETD both demonstrate favorable clinical efficacy in treating the three types of complex lumbar disc herniation while showing differences in the extent of decompression achieved. ABSTRACT Introduction Complex lumbar disc herniation (CLDH), including huge, migrated, and calcified variants, poses surgical challenges due to factors such as deep ...

Ubiquitin-dependent proteolysis of CXCL7 leads to posterior longitudinal ligament ossification. [PDF]

PLoS ONE, 2018
Ossification of the posterior longitudinal ligament (OPLL), a spinal ligament, reduces the range of motion in limbs. No treatment is currently available for OPLL, which is why therapies are urgently needed.

Wideband OPLL photonic integrated circuit enabling ultrahigh dynamic range PM RF/photonic link

Optica, 2019
The RF/photonic link is the basic element of microwave photonics. Previous RF photonic links often rely on optical intensity modulation. The inherent modulation nonlinearity leads to inadequate spurious free dynamic range (SFDR) for many sought-after ...

Delayed Postoperative Spinal Epidural Hematoma After Thoracic OPLL Surgery: A Case Report and Literature Review

Clinical Case Reports, Volume 14, Issue 1, January 2026.
ABSTRACT New axial pain with rapid neurological decline weeks after surgery for thoracic ossification of the posterior longitudinal ligament may signal delayed postoperative epidural hematoma. Immediate MRI and urgent decompression are critical. Consider occult clot‐stabilization defects such as factor XIII deficiency when routine coagulation tests are

IL17RC affects the predisposition to thoracic ossification of the posterior longitudinal ligament

Journal of Orthopaedic Surgery and Research, 2019
Background Thoracic ossification of the posterior longitudinal ligament (T-OPLL) can cause thoracic spinal stenosis, which results in intractable myelopathy and radiculopathy.
