Cubital Tunnel syndrome is the second most common compressive neuropathy. IT is common. I perform every variation of the procedures listed above. I perform this type of procedure once or twice a week. There are multiple operative procedures available, and they all work well on mild to moderate neuropathy. For severe ulnar nerve compression, there is debate as to what the ideal surgical procedure should be performed. Prolly want to stay away from a release or medial epicondyle resection for this, and move to a more agressive procedure.
THE ONLY ERROR YOU CAN MAKE, IS TO WAIT TOO LONG TO DO IT. For many reasons, the ulnar nerve does not recover as well as the median nerve (carpal tunnel syndrome).
I am a fellowship trained hand surgeon, and do revision cubital tunnel, and primary cubital tunnel surgery as a regular part of my surgical practice.
