Comparision of Short Segment Nerve Conduction Studies at the Ulnar Neuropathy around Elbow
Abstract
Objectives: We compared the sensitivity of 2 cm short segment nerve conduction study with other nerve conduction studies for the diagnosis of ulnar neuropathy around elbow. Methods: Among patients with clinical evidences of ulnar neuropathy around elbow, 56 arms of 34 males and 19 females were diagnosed as ulnar neuropathy around elbow using 1 cm short segment nerve conduction study(SSNCV). We retested them with 2 cm and 3 cm SSNCV, and conventional nerve conduction study and the diagnostic sensitivity of 2 cm SSNCV was compared with conventional, 3 cm and 1 cm SSNCV. Results: Among 56 arms, 26 arms(46%) were diagnosed as ulnar neuropathy around eldow by conventional nerve conduction study, 46 arms(82%) by 3 cm short segment nerve conduction study, and 54 arms(96%) by 2 cm short segment nerve conduction study. Conclusion: The sensitivity of 2 cm SSNCV was comparable to the sensitivity of 1 cm SSNCV. The 2cm SSNCV would first be recommended for reducing the technical errors and saving time.
Key Words: Short segment nerve conduction study, sensitivity
