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 ...

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.

Diagnostic Performance of the Darth Vader Sign for the Diagnosis of Lumbar Spondylolysis in Routinely Acquired Abdominal CT [PDF]

Diagnostics, 2023
Spondylolysis is underdiagnosed and often missed in non-musculoskeletal abdominal CT imaging. Our aim was to assess the inter-reader agreement and diagnostic performance of a novel “Darth Vader sign” for the detection of spondylolysis in routine axial ...

Factors associated with failure of bony union after conservative treatment of acute cases of unilateral lumbar spondylolysis

BMC Musculoskeletal Disorders, 2021
Background If bone union is expected, conservative treatment is generally selected for lumbar spondylolysis. However, sometimes conservative treatments are unsuccessful.
