This is the original description of latissimus dorsi tendon transfer for massive, irreparable rotator cuff tears. The authors detail the anatomic rationale, a surgical classification of tear reparability, and early results in 14 patients. The transfer aims to restore both head depression and active external rotation, functions that earlier salvage procedures could not provide.
When you face a massive posterosuperior cuff tear that cannot be repaired even after full mobilization and capsulotomy, this paper defines the salvage rationale still used today. The mental model: a massive tear removes the fulcrum the deltoid needs, so the head rides up and external rotation is lost. Debridement or a deltoid flap can depress the head but cannot restore external rotation.
The latissimus transfer is unique because its vertical line of pull depresses the head and its superolateral insertion generates an external rotation moment, correcting the arm-drop. Gerber's Type I to III classification is a practical, intraoperative reparability scale. A Type III tear (irreparable even at 60° abduction) is the target for transfer.
Remember the contraindication: this procedure fails with a deficient deltoid, because the transfer only works by making the deltoid more efficient. This is a preliminary series of 14 patients with only 4 followed beyond a year, so weight it as an origin-of-technique paper, not definitive outcome evidence.
