The effectiveness of interbody fusion devices in adult spine deformity

Adult spinal deformity is a complex pathology requiring careful consideration of patient-related parameters, comorbidities, overall clinical and radiographic alignment to determine individualized treatment. There has been an advent of interbody fusion techniques, advancements in fusion devices, and various approaches to insert spacers to achieve optimal sagittal and coronal balance. However, there is lack of clear evidence to support superiority of one technique versus others with minor differences in fusion outcomes across techniques and ability to correct deformity parameters. Ultimately, the decision is based on surgeon familiarity with techniques, fusion devices, and approaches.
