Ulnar neuropathy (often referred to as cubital tunnel syndrome) is injury to the ulnar nerve, causing numbness and tingling in the ring and pinky finger. If more severe, it can cause weakness and muscle atrophy in the hand, particularly the muscles that spread the fingers. It is most often caused by compression at the elbow. Rarely, it can be caused by compression of the nerve at the wrist. The symptoms can overlap with other conditions such as a pinched nerve in the neck or non-neurologic conditions like tendonitis, thus getting an accurate diagnosis with nerve conduction studies is important.For more information including risk factors and treatments, please refer to the PDF below.
