Results

The cadaveric study showed that the manoeuvre lead to an anteroposterior movement of the distal biceps tendon in normal and partially torn tendons, but not in completely torn tendons without retraction. The manoeuvre allowed accurate diagnosis of complete vs. partial tendon tears in 100% of cases, with surgery as a reference. (Fig. 20, Fig. 21, Fig. 22, Fig. 23, Fig. 24)

Fig. 26: Video showing the normal range of movement of the biceps in supination. The movement is from medial to lateral and in depth. The Lacertus Fribrosus is pulled from its medial insertion.

Fig. 28: Video showing the range of movements the total rupture of the biceps tendon; theses movements are replaced by a slight traction of the Lacertus Fibrosus that is unscathed.

Fig. 19: Tear Dynamics: A) The normal range of movement of the biceps in supination is from medial to lateral and in depth. The Lacertus Fribrosus is pulled from its medial insertion. B) With the tear of 50% of the biceps tendon there is a decreases in the lateral movement and in the depth. C) With the total rupture of the biceps tendon theses movements are replaced by a slight traction of the Lacertus Fibrosus that is unscathed.
