Objective To assess the correlation between ultrasonographic and electrodiagnostic findings to determine the localization of the ulnar trapping at the elbow. Design Cross-sectional and noninterventional trial. Setting Physical medicine and rehabilitation department of a teaching hospital. Participants Patients (N=14) diagnosed with ulnar nerve entrapment using short-segment nerve conduction study. Interventions The elbow area was divided into 4 segments with 2-cm intervals. All patients underwent ultrasonographic and electrodiagnostic examinations. Main Outcome Measures The nerve conduction velocity (NCV) of each segment was measured. The cross-sectional area (CSA) of the ulnar nerve was measured at 5 levels. The proximal CSA/distal CSA ratio (PDR) was calculated by proportioning the CSA values for each segment. The highest PDR was accepted as a trapping segment, whereas the segment with the lowest NCV was accepted electrophysiologically (provided it was Results A total of 80 PDR and NCV measurements were taken from 20 elbows. A statistically significant negative correlation (r=−.554; P<.001 was found between general pdr and ncv values. when we assumed that the value as criterion standard for diagnosis cutoff to be with a sensitivity of specificity minimum maximum were mostly seen in third segment compatible cubital tunnel.> Conclusions Ultrasonography seems to be advantageous because it is more comfortable for the patient and requires shorter time than does electroneuromyography. To our knowledge, this is the first study to detect ulnar nerve entrapment by using not only CSA but also PDR as a ratio method with ultrasound. |
