Long head of the biceps tendon pain: differential diagnosis and treatment.

Unlabelled: Though the role of the long head of the biceps tendon (LHBT) in shoulder pathology has been extensively investigated, it remains controversial. Historically, there have been large shifts in opinions on LHBT function, ranging from being a vestigial structure to playing a critical role in shoulder stability. Today, despite incomplete understanding of its clinical or biomechanical involvement, most investigators would agree that LHBT pathology can be a significant cause of anterior shoulder pain.
