X-ray Imaging for Post-Laminectomy Patient with Persistent Pain Before Physical Therapy

Initial Imaging Approach

• Upright radiographs of the lumbar spine, including flexion and extension views, should be ordered initially to assess hardware integrity, alignment, and adjacent segment disease in post-surgical patients with persistent or new pain, according to the American College of Radiology 1, 2
• Flexion and extension radiographs should be included to identify segmental motion and potential instability, which is essential information before beginning physical therapy, as recommended by the American College of Radiology 1, 3
• Functional radiographs provide valuable information about axial loading and spinal stability that static imaging cannot capture, as noted by the American College of Radiology 3

Rationale for Starting with X-rays

• Radiographs are complementary to advanced imaging and provide important initial structural information for post-surgical patients, according to the American College of Radiology 1, 2
• X-rays can detect potential contraindications to physical therapy, such as hardware complications, adjacent segment degeneration, vertebral body nonunion or pseudoarthrosis, and spinal instability or abnormal motion, as identified by the American College of Radiology 1, 2, 4
• X-rays are readily available, cost-effective, and involve minimal radiation exposure compared to CT, as stated by the American College of Radiology 3, 4

When to Consider Advanced Imaging

• Advanced imaging may be indicated if radiographs show concerning findings requiring further evaluation, according to the American College of Radiology 1
• Advanced imaging may be indicated if the patient has severe or progressive neurological symptoms, as recommended by the American College of Radiology 1, 3
• MRI without IV contrast would be the next appropriate study to evaluate for recurrent stenosis, disc herniation, or epidural fibrosis, as suggested by the American College of Radiology 1, 2

Common Pitfalls to Avoid

• Skipping initial radiographs and proceeding directly to advanced imaging can miss important structural issues that could affect physical therapy safety, as warned by the American College of Radiology 1
• Failure to obtain flexion/extension views may miss dynamic instability that could be exacerbated by physical therapy, according to the American College of Radiology 1, 3
• Relying solely on old imaging studies may miss new pathology that has developed in the decade since surgery, as noted by the American College of Radiology 3, 4
