Abstract PDF: OBJECTIVES
To report cubital tunnel syndrome due to repetitive motions.
METHODS
A worker complaining muscle weakness and atrophy of the right hand intrinsic muscles admitted to a hospital. We evaluated him with blood tests, neurophysiologic studies (NCV & EMG), plain X-ray and US at the both elbows. We investigated his occupational history, and videotaped his work motions based on the work cycle at his previous work site. Finally, an ergonomics expert analyzed the motions using rapid upper limb assessment (RULA).
RESULTS
NCV & EMG studies reveals slow conduction velocity on both ulnar nerve across the elbow, more severely in the right side. US shows us compatible finding with diffuse neuritis of both ulnar nerves at both elbows. RULA score is 7.
CONCLUSION
We confirmed that the workers symptoms were related to his previous jobs demanding repetitive motions using the elbow joints. It is necessary that we should prepare appropriate measures to evaluate, prevent, rehabilitate, and help injured workers to return to work.
