P32. Can CT-based bone mineral density predict proximal junctional fracture?

Proximal junctional fractures (PJFr) can be a catastrophic complication associated with adult spinal deformity surgery. Presence of osteoporosis has been shown to be one of the risk factors for PJFr. Dural-Energy X-Ray Absorptiometry (DEXA) scans are standard screening tools for diagnosis of osteoporosis. However, spinal DEXA scores have been reported to be flawed with regional sclerosis associated with spinal degeneration representing a possible confounder to the study. Recently, investigators have reported on the use of a computed tomography (CT) scan surrogate in place of spinal DEXA scores.
