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

Luxation of the long head of the biceps is a disorder, well detectable by the ultrasound during the examination of the long head of the biceps in the transversal section. A ligament stretched between the tuberculum major and tuberculum minor fixes the tendon under the normal circumstances in the bicipital sulcus. If there is an disorder of this ligament, or if the sulcus is too shallow, a dislocation of this sulcus can occur (mostly medially).

Symptoms of the Dislocation of the Tendon of the Long Head of the Biceps

	Painful flexion against the resistance in the elbow joint. The pain is of course localized in the area of the bicipital sulcus.
	Painful abduction in the shoulder joint.
	A skipping of the tendon in the area of the sulcus during a movement in the shoulder joint which can be touched by fingers.
	A restriction of motility of the shoulder girdle.

During the exhibition of a picture information from the ultrasound examination we will not rely too much on these unclear symptoms for a determination of a diagnosis.
