This is the oldest method for treating rotator cuff tears and is suitable for large complex tears that may require additional reconstruction e.g. tendon transfer which is performed when a damaged tendon can not be reattached to the top of the humerus hence a tendon from a different body part (usually the latissimus
dorsi tendon of the back) is implanted to repair the rotator cuff.
The latissimus
dorsi is found to twist under the teres major to insert more anteriorly, while more recent investigation shows that in some cases (25 %) the latissimus
dorsi and teres major
tendons fuse before their respective insertions (Goldberg et al. 2009).
