Anatomy Of The Latissimus Dorsi Muscle - Everything You Need To Know - Dr. Nabil Ebraheim

Educational video describing the anatomy associated with the Latissimus Dorsi muscle. The latissimus dorsi muscle is the broadest muscle of the back, which is partially covered by the trapezius muscle. It originates from the iliac crest, the thoracolumbar fascia, the spinous processes of the inferior six thoracic vertebrae, and the inferior three or four ribs. The latissimus dorsi inserts into the intertubercular groove at the front of the humerus. Anatomically, the latissimus dorsi is a muscle of the back, however functionally, it is a muscle of the upper limb. The latissimus dorsi is responsible for adduction, medial rotation, and extension of the shoulder (similar to the action of the teres major). The pectoralis major is also a synergist muscle. The latissimus dorsi is supplied by the cervical nerve roots of C6, C7, and C8, through the thoracodorsal (long thoracic) nerve. The latissimis dorsi is a strong muscle that is helpful in performing sports, such as swimming, gymnastics, and rowing. The latissimus dorsi is used as a free flap especially with open fractures in the distal third of the tibia. The latissimus dorsi can also be used as a tendon transfer in the treatment of massive rotator cuff tears. A latissimus dorsi tendon transfer is used in young adult patients with irreparable cuff tears provided that the patient has intact subscapularis function and no arthritis. An intact subscapularis function is valuable in this situation. It is interesting to note that the pectoralis major transfer is used for chronic subscapularis tendon rupture. To achieve success of latissismis dorsi transfer, the subscapularis tendon function must be intact. A latissimus dorsi rupture is rare. Rupture is a clinical diagnosis confirmed by MRI. Treatment typically consists of rest, physical therapy, or surgery depending on the situation.
