The latissimus dorsi is a potential source of muscle for breast reconstruction surgery after mastectomy (e.g., Mannu flap) [12] or to correct pectoral hypoplastic defects such as Poland's syndrome. [13] [14] An absent or hypoplastic latissimus dorsi can be one of the associated symptoms of Poland's syndrome. [15] [16]

The "lat" sometimes added before "pull-down" commonly refers to the latissimus dorsi used in the movement. Most exercises describe the muscle that is involved and the direction of the exercise e.g. biceps curl, triceps extension, leg press, hamstring curl, abdominal curl and so on.
latissimus dorsi and teres major, long head of triceps, posterior fibers of the deltoid Medial rotation of the arm [16] Medial rotation of the arm is most easily observed when the elbow is held at a 90-degree angle and the fingers are extended so they are parallel to the ground.
It penetrates into the substance of the latissimus dorsi muscle near the lateral border of scapula. [5] It follows the course of the subscapular artery, along the posterior wall of the axilla to the latissimus dorsi muscle, [1] in which it may be traced as far as the lower border of the muscle.

[14] For example, with the latissimus dorsi muscle, the origin site is the torso, and the insertion is the arm. When this muscle contracts, normally the arm moves due to having less mass than the torso. This is the case when grabbing objects lighter than the body, as in the typical use of a lat pull down machine.
