Latissimus Dorsi Tendon Rupture

Abstract

Isolated injury to the latissimus dorsi is rare. Partial tendon tears may be successfully treated nonsurgically. Complete tendon ruptures require surgical repair. Tendon repair can be approached either through an anterior deltopectoral incision with a secondary small posterior axillary incision or through a long posterior axillary incision. Suture anchors can be used to repair the latissimus dorsi to the humeral attachment. Although the literature is limited to single-patient case series, most patients have returned to full athletic activity after surgical repair.

Single incision latissimus dorsi surgical technique: a three button repair

“…5 The overall suture anchor repair literature, regardless of surgical technique, has been excellent with a high percentage of patients returning to full activity. 6 The senior author prefers a small posterior axillary single incision approach comparable to previously described single incision techniques. 1,7,8 This incision combined with lateral decubitus positioning provides excellent exposure of the retracted tendon and the humeral insertion.…”

Tendon transfers for irreparable rotator cuff tears

“…It inserts medial to the PM; and lateral and proximal to the TM on the humerus. 7 It derives its neurovascular supply from the thoracodorsal nerve, a branch of the posterior cord of the brachial plexus and thoracodorsal artery, a branch of the subscapular artery. 8 The axillary and radial nerves are closest to the LDT insertion when the arm is flexed, and farthest when the arm is internally rotated.…”

“…abduction at the shoulder joint. 2 MRI of the affected extremity is the recommended imaging modality of choice; however, ultrasound can identify disruptions in the muscle most commonly at the myotendinous sections. 3 If MRI is available, a non-contrast study of the proximal humerus should be ordered.…”
