To discuss the presence of spondylolysis at L2 in identical twins.

Clinical features
Twin 61-year-old brothers reported insidious low back pain (LBP) of relatively recent onset. Both engaged in running as their main form of exercise. One had spondylolisthesis and history of significant traumatic incident; the other had no spondylolisthesis but a much more strenuous running regimen.

Intervention and outcome
Both patients underwent a course of chiropractic treatment for mechanical LBP and reported a 50% overall improvement in symptoms.

Spondylolysis at L2 is uncommon, and although a familial component regarding weakness of the pars interarticularis has been demonstrated in the literature, spondylolysis at L2 in twins is extremely rare. Questions remain regarding the cause of spondylolisthesis in patients.
