Patient Data

Age: 45
Gender: Male

MRI Lumbar spine

Grade I spondylolisthesis of L5/S1 with a degenerated disc. Within the limitations of the study it is possible to spot bilateral pars articularis defects in L5. 

Case Discussion

Spondylolysis is a defect in the pars interarticularis of the neural arch, the portion of the neural arch that connects the superior and inferior articular facets. As demonstrated in this case, the vast majority of these lesions occur at the L5 level (~90%) 1.

The association of spondylolysis and spondylolisthesis is common and occurs in more than 50% of the cases 1

This case represents an outpatient exam, and no further clinical information or clinical feedback were available.
