Inter- and intra-observer reproducibility of ultrasound analysis of the long head of the biceps.

Introduction: Ultrasound assessment of the long head of the biceps (LHB) is difficult. The aim of the present study was to analyze the inter- and intra-observer reproducibility of 2 ultrasound cross-sections not previously assessed: humeral head apex (image 1) and bicipital groove entrance (image 2).

Hypothesis: These ultrasound cross-sectional images allow reliable and reproducible analysis of the intra-articular LHB.
