Dynamic Biceps Rerouting for Irreparable Posterior-Superior Rotator Cuff Tear

Area of Science:

• Orthopedic Surgery
• Shoulder Arthroscopy
• Rotator Cuff Repair

Background:

• Irreparable posterior-superior rotator cuff tears (IPSRCT) present a significant clinical challenge.
• Current treatment options for IPSRCT often involve complex procedures with varying outcomes.
• The long head of the biceps (LHB) has been explored for superior shoulder augmentation, but optimal techniques are still under investigation.

Purpose of the Study:

• To introduce and describe a novel arthroscopic dynamic LHB rerouting technique for managing IPSRCT.
• To evaluate the feasibility, safety, and potential benefits of this new surgical approach.

Main Methods:

• The technique involves arthroscopic LHB rerouting into a newly created bicipital groove on the greater tuberosity.
• The procedure includes opening the native bicipital groove and performing a side-to-side rotator cuff repair over the rerouted LHB.
• Crucially, this method does not require LHB fixation.

Main Results:

• Clinical experience suggests the arthroscopic dynamic LHB rerouting technique is easily and safely performed when specific guidelines are followed.
• The procedure aims to provide superior shoulder augmentation for patients with IPSRCT.

Conclusions:

• Arthroscopic dynamic LHB rerouting offers a promising new insight into superior shoulder augmentation for irreparable posterior-superior rotator cuff tears.
• This technique presents a potentially valuable addition to the surgical armamentarium for managing complex rotator cuff pathology.
