Ultrasonographic Validation of Anatomical Landmarks for Localization of the Tendon of the Long Head of Biceps Brachii

Table 1

Medial epicondyle vertical line related landmark: average distance between the biceps groove and medial epicondyle vertical line were measured at 0° and 45° external rotation. Correlation coefficients between the distance and weight, height, and BMI were calculated at 0° and 45° of shoulder external rotation. CC: correlation coefficients. BMI: body mass index.

	Average distance (95% CI)	CC between the distance and weight	CC between the distance and height	CC between the distance and BMI
0° neural position	9.3 mm (6.8–11.8)	0.04	0.32	0.26
45° external rotation	21.5 mm (18.9–24.1)	0.10	0.42	0.37
