The use of diagnostic imaging to assess spinal arthrodesis.
Despite advances in surgical techniques and internal fixation devices, pseudarthrosis remains a significant factor in the clinical failure of attempted fusions in the cervical, thoracic, and lumbar spine. This article reviews the use of diagnostic imaging in the assessment of spinal fusion, with a focus on the accuracy of different imaging modalities based on surgical exploration. A cost-effective strategy for the radiographic follow-up of patients after spinal fusion surgery also is presented.
