OBJECTIVES: To investigate the patterns of power Doppler signals on the long head
of the biceps tendon at asymptomatic controls and shoulders with clinically
diagnosed biceps disorder. SETTING: Hospital
rehabilitation department. PARTICIPANTS: Asymptomatic adults (n=27) were included
in the control group, and patients with unilateral biceps disorder (n=17) were
recruited for the patient group. Basic gray color ultrasound screening was
performed for rotator cuff tendons antecedently. INTERVENTIONS: Not applicable.
MAIN OUTCOME MEASURES: Three scan views were taken on the anterior shoulder by
power Doppler sonography, including the transverse plane of the long head of the
biceps tendon, and the longitudinal planes along the lateral and medial edge of
the bicipital groove. We compared the patterns and the power Doppler signal area
within and between both groups. RESULTS: In shoulders of healthy controls and the
asymptomatic side of patients, the power Doppler signal area of the longitudinal
planes along the lateral edge of the bicipital groove was significantly larger
than that along the medial edge of the bicipital groove. However, there was no
significant difference in the painful side of patients. Moreover, the painful
shoulders had a higher prevalence of power Doppler signal medial to the biceps
tendon in the transverse plane, which paralleled bicipital peritendinous effusion
and rotator cuff abnormalities. CONCLUSIONS: The power Doppler signal was more
frequently observed medial to the biceps tendon in shoulders with clinically
diagnosed biceps disorder. Whether shoulders with this specific power Doppler
signal pattern benefit more from anti-inflammatory therapy needs further exploration.
