Abstract
To determine if the term “back pain” has uniform meaning to spinal surgeons.
A survey of specialists attending an international meeting on spinal surgery. Participants were shown 5 schematic pain drawings and then asked to categorize the pain as either back or leg pain.
An international cohort of neurosurgeons, orthopaedic surgeons and trauma surgeons (n=104) attending a European spinal meeting.
67% of participants were orthopaedic surgeons and 22% neurosurgeons. 42% were in full time spinal practice. 50% had been in independent practice for 7 years or more. There was no statistical difference in the responses of neuro- and orthopaedic surgeons (Fisher's test, p>0.05).
The more rostral the pain, the more likely it was to be deemed “back pain”. However, unilateral pain was more likely to be deemed “leg pain” than its bilateral symmetrical equivalent no matter how rostral the distribution. Unilateral mid-lumbar pain was considered “back pain” by 48%, symmetrical bilateral mid-lumbar pain in 87%. Pain in the buttocks was considered “back pain” in 50% whether unilateral or bilateral.
This study demonstrates significant discrepancy in what is considered to be back pain and leg pain by a broad spectrum of spinal surgeons. Back pain and leg pain are often investigated and managed in different ways. This differentiation is difficult to justify until we know the answer to the question, what is back pain?
