Rupture of the Long Head of the Biceps in the Transversal Section

If the tendon of the long head of the biceps is not seen inside the bicipital sulcus10 during the ultrasound examination, a complete rupture of the long head of the biceps can be supposed. At the rupture of the long head of the biceps there is a shrinkage of the tendon and the muscle distally, so it is not possible to find an adequate structure of the tendon  in the sulcus. This finding is rare at rheumatoid diseases maybe because the tendon is mostly firmly fixed by granulations in the sulcus11.

10 There is also an empty sulcus at luxation of the tendon from bicipital sulcus, therefore there is necessary to look for the tendon in another localization than under normal circumstances.

11 A longitudinal section is more advantageous for the ultrasound examination of parcial structures.
