Osteoporotic Vertebral Compression Fractures Adjacent to Previous Spinal Fusion
Advances in surgical technique and instrumentation have enabled surgeons to treat symptomatic adult spinal deformity in high-risk populations such as elderly and osteoporotic patients that previously had more limited treatment options. Adjacent segment disease is a significant complication of spinal deformity surgery and is especially relevant in the osteoporotic population. Consequences of osteoporotic vertebral compression fractures in segments adjacent to previous spinal fusion exist on a spectrum ranging from asymptomatic, benign PJK on one end to severe (proximal junctional failure) PJF on the other. As the elderly cohort of the population continues to increase, further research will be required to better understand the causes and treatment of the condition.
