Dermal Allograft and Biceps Superior Capsule Reconstruction for Massive Irreparable Rotator Cuff Tears.

Since the use of autologous fascia lata for superior capsule reconstruction of massive irreparable rotator cuff tears (MIRCTs), the technique has evolved into various modifications, including dermal allografts, long head of the biceps tendon (LHBT), and combinations of both, which will be discussed in this article. After making sure the remnant cuff cannot be restored to the anatomical footprint of the supraspinatus, a double-loaded or triple-loaded, suture-based anchor is inserted 5-8 mm posterior to the bicipital groove to secure the long head of the biceps (LHBT) initially. A bone trough is made 5 mm posterior to the bicipital groove.

Methods: We conducted a retrospective study on patients receiving primary surgery of combining trapeziectomy with ligament reconstruction and tendon interposition and suture button suspensionoplasty for advanced osteoarthritis from 2017 to 2023.

Techniques for Lower Trapezius Transfer Using Achilles Allograft in Irreparable Posterosuperior Rotator Cuff Tears.

The management of irreparable rotator cuff tears presents significant challenges, particularly in active individuals experiencing functional limitations, such as reduced forward elevation and deficits in both external and internal rotation. Traditional latissimus dorsi (LD) tendon transfer has shown effectiveness in reducing pain associated with posterosuperior cuff tears but often yields inconsistent functional outcomes. This is largely due to the LD's primary role as an internal rotator, which limits its capacity to restore normal shoulder biomechanics.
