• What projections can be taken to determine the range of motion of the spine at the level of the spinal fusion?
• FLEXION / EXTENSION
• BENDING (LATERAL)

bending
•These projections are functional studies of the lumbar spine to determine the range of motion of the spine at the point of spinal fusion.• Following spinal fusion surgery, the orthopedic physician or neurosurgeon may order a study to evaluate the flexibility of the spine.•These projections will require the patient to assume different positions to determine how much flexibility of the spine has returned.•Early signs of scoliosis and herniated intervertebral disk or HNP can be evaluated with these projections.
