- Abstract
- Objective To investigate the optimal sonographic method for diagnosing carpal tunnel syndrome (CTS) in patients with diabetic sensorimotor polyneuropathy (DSP). Methods A total of 190 participants were divided into four groups based on DSP history and electrodiagnostic results of CTS. The absolute parameters were measured at baseline and the relative values were calculated: maximal cross-sectional area (CSA) of the median nerve throughout the carpal tunnel (Mmax), median nerve CSA at the forearm level (Mf), ulnar nerve CSA at the pisiform level (Upi), difference between Mmax and Mf (Delta MM), and difference between Mmax and Upi (Delta MU). Then, the optimal ultrasonographic parameters for diagnosing CTS, according to the presence of DSP, using absolute and relative cutoff values were analyzed. Results Median and ulnar nerve CSAs were significantly larger in the DSP group than in the control group. In the DSP participants, the mean Mmax, Delta MM, and Delta MU values were significantly larger in patients with both DSP and CTS than in patients with DSP only. The Mmax thresholds of 9.5 mm(2) in the control group and 11.5 mm(2) in the DSP group showed the greatest sensitivity and specificity for diagnosing CTS. The Delta MM thresholds of 2.5 mm(2) and Delta MU thresholds of 4.5 nim(2) had the greatest sensitivity and specificity in both the DSP and control groups. Conclusion Measurement of Mmax, Delta MM and Delta MU is an optimal ultrasonographic evaluation method for diagnosing CTS in patients with DSP.
