Spine Surgeons Sometimes Confuse Neck and Elbow Nerve Issues (Small Survey)

In a small survey of 24 spine surgeons attending a cervical spine course, many could not differentiate between C8-T1 radiculopathies (neck nerve issues) and ulnar neuropathy (elbow nerve issues) based on sensory and motor function. Only 63% correctly identified the sensory distribution of the ulnar nerve, and none could identify all the hand muscles controlled by C8-T1 without also naming incorrect ones.

Possible Conflicts of Interest

None identified

Identified Weaknesses

Small sample size

The sample size of the study was relatively small, comprising only 24 spine surgeons. This limits the generalizability of the findings and may not accurately represent the knowledge base of the broader spine surgeon population.

Selection bias

The study participants were all attendees of a cervical spine course, potentially creating a selection bias. Surgeons specializing in other areas of the spine might have different levels of familiarity with upper extremity neuroanatomy.

Self-reported data

The study relied on a self-administered questionnaire, which can be subject to response bias and may not accurately reflect participants' true knowledge or clinical practice.

Rating Explanation

This study highlights an important knowledge gap among spine surgeons, but the small sample size, selection bias, and reliance on self-reported data limit the generalizability of the findings. The methodology is appropriate for a preliminary investigation, but further research with a larger and more diverse sample is needed to confirm these findings.
