Summary

This research is studying two surgical procedures in a large group of people to learn about how well these procedures work as a treatment for ulnar neuropathy at the elbow (UNE). Researchers want to see which surgery is more helpful for people with ulnar neuropathy. This research will determine if one surgery is better than the other to alleviate symptoms.
