How Accurate Are We in Detecting Biceps Tendinopathy?

Abstract

Biceps tendon pain is frequently called biceps "tendinitis," or inflammation of the biceps tendon. Histologic analysis of biceps tendon biopsies demonstrates changes in tenocyte size, ground substance, collagen organization, and vascularity observed with many different tendinopathies. There are distinct symptoms of biceps tendinopathy and a few provocative maneuvers can help make the diagnosis. Imaging studies (eg, MRI) can show changes in signal sequence or tears. However, MRI has a low sensitivity and frequently results in missed or misdiagnosed biceps pathology. Clinical decision making is best guided by a strong clinical suspicion based on patient history, physical examination, and MRI.
