cubital tunnel syndrome ulnar nerve syndrome)

Definition of

Ulnar nerve compression syndrome due to compression of the ulnar nerve in the cubital tunnel or ulnar sulcus in the elbow, which is why it is also known as ulnar groove syndrome or sulcus ulnaris syndrome. The ulnar nerve is known to most people as the nerve that is irritated when the „musician’s bone“ is bumped.
It is debated whether the presence of an epitrochleoanconeus instead of an Osbourne ligament is correlated with a lower tendency to cubital tunnel syndrome (sulcus ulnaris syndrome/ulnar groove syndrome) when the muscle is normal, but predisposes to it in hypertrophy.

ICD G56.2

Cause
