Complete tear of the long head biceps tendon - "groove entry lesion"


Complete tears of the long head biceps tendon (LHBT) are frequently associated with its previous degeneration and are commonly seen along a hypovascular segment of the LHBT found 1.2-3 cm from the tendon origin extending from the intra-articular portion of the tendon at the mid humeral head level into the superior portion of the intertubercular sulcus. This particular LHBT injury has been named the “groove entry lesion”.
