Characteristics of lumbar spondylolysis: L5 versus non-L5 [PDF]
BMC Musculoskeletal DisordersBackground 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.
