TY - JOUR T1 - CUbital tunnel syndrome AU - Kanakamedala R, Chaudhuri G Y1 - 1979/09/14 N1 - 10.1001/jama.1979.03300110013010 JO - JAMA SP - 1139 EP - 1139 VL - 242 IS - 11 N2 - To the Editor.—  Charles B. Clark, MD (241:801, 1979), describes symptoms and treatment of cubital tunnel syndrome. He mentions seven tests in diagnosing and localizing compression of the ulnar nerve. He states: "In my experience, these tests are more reliable than electrical studies, which include nerve conduction times and electromyography."The tests he briefly describes are useful in diagnosing cubital tunnel syndrome; however, they are not absolutely conclusive of the diagnosis. Nerve root compression and thoracic outlet syndrome involving C8-T1 segments can mimic some of the symptoms and signs he described in the article. These need to be excluded before submitting the patient for surgery. This can be done only by doing motor and sensory nerve conduction studies at various segments of the ulnar nerve (above, across, and below the elbow), F-wave latency and conduction velocity on both sides (if necessary), and electromyography. In addition, nerve conduction velocity studies and SN - 0098-7484 M3 - doi: 10.1001/jama.1979.03300110013010 UR - http://dx.doi.org/10.1001/jama.1979.03300110013010 ER -
