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

Table 2

Coracoid process landmark: average distance between biceps groove and coracoid process were measured at 0° and 45° external rotation. Correlation coefficients between the distance and weight, height, and BMI were calculated at 0° and 45° 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	44.0 mm (41.5–46.5)	0.36	0.36	0.18
45° external rotation	62.2 mm (59.2–65.2)	0.41	0.54	0.13
