Ultrasound-Guided Percutaneous Tenotomy of Biceps Tendon : Technical Feasibility on Cadavers

We tested the technical feasibility of ultrasound-guided percutaneous tenotomy of the long head of the biceps tendon (LHBT) in cadavers. Both shoulders of two fresh cadavers were scanned anteriorly to evaluate the extra-articular portion of the LHBT. Under ultrasound monitoring, a scalpel was advanced obliquely up to touch the superficial medial side of the LHBT, cutting it until the tendon was not visible anymore. Ultrasound evaluation was repeated after the procedure, and anatomic dissection was performed. The procedure was 100% feasible: four cuts were made to completely sever the tendon; the duration was less than 1 min. Skin incision measured 5 mm in two cases and 6 mm in two cases. Anatomic dissection confirmed complete tendon cut in all cases with proximal and distal tendon stumps very close to each other. Ultrasound-guided percutaneous LHBT tenotomy was 100% technically feasible in cadavers with a quick procedure and minimal cutaneous incision.
