Latissimus dorsi tendon transfer for massive rotator cuff tears: a cadaveric study.
Certain massive defects of the rotator cuff tendinous insertion cannot be repaired primarily to the greater tuberosity. If restoration of strength is an important treatment goal to the patient, then a tendon transfer may be considered. Ten cadaver shoulders were dissected to define the anatomy of the latissimus dorsi tendon (LDT) and its distance relationship to the axillary and radial nerves with the arm in various positions. The axillary nerve lies superior to the LDT insertion, and the radial nerve passes medial and inferior to the LDT insertion. With the arm internally rotated and the shoulder flexed, the distances from the axillary and radial nerves to the LDT insertion were 2.3 cm and 2.8 cm, respectively. With the arm internally rotated and the shoulder abducted, the distances from the axillary and radial nerves to the LDT insertion were 1.8 cm and 2.0 cm, respectively. Understanding specific anatomic relationships is one of the factors contributing to the safety of the LDT transfer procedure with respect to nerve injury.
