Table 2. Mean CSAs of the ulnar nerve.
| Control (n=28) | Normal (n=24) | CTS (n=34) | DPN (n=26) | DPN+CTS (n=28) | |
|---|---|---|---|---|---|
| URUE (mm2) | 5.6 ± 0.8 | 5.5 ± 0.9 | 6.2 ± 1.6 | 6.4 ± 1.9 | 6.2 ± 1 |
| UDIS (mm2) | 5.9 ± 0.8 | 5.9 ± 1.1 | 5.6 ± 0.9 | 6.1 ± 1 | 6.1 ± 0.8 |
| UPROX (mm2) | 6.1 ± 1 | 5.9 ± 1.2 | 5.5 ± 0.9 | 6.5 ± 1.4* | 6 ± 0.9 |
| UEPI (mm2) | 7.7 ± 1.1 | 8.1 ± 1.6 | 9.2 ± 1.9* | 9.2 ± 1.6* | 9.3 ± 1.4* |
Post hoc analysis: p=0.014 for DPN vs. CTS at the UPROX; p=0.01, p=0.003, and p=0.002 for DPN vs. control, CTS vs. control, and DPN+CTS vs. control at the UEPI, respectively. CSAs: cross-sectional areas; URUE: ulnar nerve at the radioulnar joint; UDIS: ulnar nerve at the distal one-third level of the forearm; UPROX: ulnar nerve at the proximal one-third level of the forearm; UEPI: ulnar nerve at the medial epicondyle. *p<0.05
