Ultrasound-guided percutaneous tenotomy of the long head of the biceps tendon: a non-reliable technique.

Purpose: To evaluate the feasibility of ultrasound-guided percutaneous tenotomy of the long head of the biceps tendon via a keyhole incision.
Methods: This was an anatomical study performed on twelve embalmed cadaveric shoulder joints. The rotator cuff and the position of the long head of the biceps tendon were explored by ultrasound prior to beginning the procedure. The biceps tenotomy was performed under ultrasound guidance by a highly experienced sonographer who was trained in shoulder tendon exploration. Arthroscopic exploration of the shoulder was performed immediately after the percutaneous biceps tenotomy to assess the quality and the location of the biceps tenotomy.
Results: Three out of twelve tendons (25%) were completely sectioned at the level of the glenoid insertion. More seriously, iatrogenic lesions of the cartilage of the humeral head, the supraspinatus tendon and the subscapularis tendon were observed.
Conclusion: This study shows that ultrasound-guided percutaneous tenotomy of the long head of the biceps tendon is not reliable.
