From: Anatomic relations of the median nerve to the ulnar insertion of the brachialis muscle: safety issues and implications for medial approaches to the elbow joint

Fig. 2

Comparison of distances between median nerve and ulnar insertion of the brachialis muscle obtained in different study conditions, highlighting the role of forearm movements. Each box represents the mean distance normalized to the TED. The error bars show the 95% confidence interval values. A Tukey’s multiple comparisons test was used to test for differences between measurements obtained from the same point of the brachialis insertion and at the same degree of elbow flexion, differing between each other only for forearm rotation. N neutral position, P pronation, S supination, TED transepicondylar distance. Only p values < 0.05 are indicated: *p < 0.05; **p < 0.01; ***p < 0.001; ****p < 0.0001
