The Ferguson tilt-up view is used primarily to evaluate which vertebral level in pars fractures?

This radiographic projection is designed to visualize pars interarticularis fractures at the L5 level. By tilting the patient, the L5 pars interarticularis is brought into a better profile and reduced superimposition from the pelvis and lower spine, making nondisplaced fractures easier to spot. Spondylolysis most commonly affects L5 in young athletes, so this view is optimized for that level. While pars defects can occur at other levels, the Ferguson tilt-up projection specifically targets L5, which is why it’s used primarily for evaluating pars fractures at that level.
