Which condition must be ruled out prior to conducting a discography?

Prior to conducting a discography, it is vital to rule out psychogenic pain due to its potential to affect the interpretation of the test results. Discography is a minimally invasive procedure where contrast material is injected into the intervertebral disc to evaluate disc-related pain and assess the integrity of the disc structure. However, if a patient is experiencing pain that is primarily psychogenic, it could produce misleading results, suggesting that pain is coming from the disc when it is actually stemming from psychological factors.

Understanding the nature of the patient's pain is critical because psychogenic pain often does not respond to typical pain management strategies or the findings from physical exams and imaging studies. Thus, confirming that pain is of a neuropathic or musculoskeletal origin is essential to ensure that the discography accurately reflects the physical pathology of the spine.

In contrast, while ruling out fractures in the vertebral column, muscle strains, or neuropathy may be important considerations for overall spinal assessment and management, they do not directly impact the validity of the discography results to the same extent that ruling out psychogenic pain does. Ensuring a clear pathophysiological basis for the pain being investigated with discography is paramount to obtaining meaningful diagnostic information.
