The Implementation of Persistent Spinal Pain Syndrome (PSPS): Mechanism‐Based Recommendations

Pain Practice, Volume 26, Issue 1, January 2026.
ABSTRACT Background In 2021, the term persistent spinal pain syndrome (PSPS) was introduced. PSPS type 2 (PSPS‐T2) replaced the unsatisfactory term failed back surgery syndrome (FBSS). PSPS type 1 (PSPS‐T1) is a clinical picture of signs and symptoms of FBSS but without prior surgery. PSPS applies to any spinal level.

Age and Spinal Level as Predictors of Lumbar Disc Degeneration in Humans and Mice: A Comparative Analysis

JOR SPINE, Volume 8, Issue 4, December 2025.
Mouse models are commonly used to study IVD degeneration and related neurological conditions that especially impact elder population. However, how well mice replicate human pathology remains unclear. This study compared lumbar IVD degeneration patterns across age and spinal levels in humans and mice.

Vertebral body bone mineral density in patients with lumbar spondylolysis: a quantitative CT study

Diagnostic and Interventional Radiology, 2017
Purpose:Spondylolysis is known to be a part of a disease process, which describes a defect in the pars interarticularis of vertebra. We aimed to use quantitative computed tomography (QCT) to measure vertebral body bone mineral density (BMD) in patients ...

Effects of Spina Bifida Occulta on Bone Union in Fifth Lumbar Spondylolysis

Spine Surgery and Related Research, 2023
Introduction: The effect of spina bifida occulta (SBO) on bone union in lumbar spondylolysis is controversial. The study aim was to assess the effect of SBO on bone union after conservative treatment of L5 spondylolysis, the most common level.

Growing Old at Tombos: A View of Older Adults in an Ancient Egyptian‐Nubian Community

American Journal of Biological Anthropology, Volume 187, Issue 4, August 2025.
ABSTRACT Objectives The experiences of older adults in ancient communities are often overlooked in studies due to many factors, such as preservation, methodological issues, and less frequent mention in available texts. Materials and Methods This study combines community‐ and individual‐level data to explore life for older adults at the ancient Egyptian/

Characteristics of lumbar spondylolysis: L5 versus non-L5

BMC Musculoskeletal Disorders
Background Fifth lumbar vertebra (L5) spondylolysis has a lower bone union rate than non-L5 spondylolysis, but the reason for this is unknown. This study aimed to evaluate the differences in patient and lesion characteristics between L5 and non-L5 ...
