Pectoralis Tendon Tear Repair in Chicago

The pectoralis major is the large muscle on the upper front part of the chest. The tendon of the pec major is attached to the humerus (upper arm bone). Tendons are tissues that connect muscle to a place on the bone called the insertion site. This is where tendons are most likely to rupture (tear). A pectoralis major tendon rupture is a rare shoulder injury that typically occurs in weight lifters. In a pectoralis major tendon rupture, the tendon rips partially or fully off its insertion site at the upper arm bone.

Pectoralis Tendon Tear Repair in Chicago

A pectoralis major tendon rupture is most commonly seen in weight lifters.

Why treatment is required

Pectoralis Major Tendon Repair

A pectoralis major tendon rupture is an injury most commonly seen in weight lifters. Other activities related to this injury include boxing, football, wrestling, water skiing, and rodeo. People with jobs requiring manual labor may also be at risk for pectoralis major tendon tears. Nearly all reported cases have been in men.

Pectoralis major tendon injuries are often caused by eccentric loading. An eccentric load means that a force is being applied to the muscle as it lengthens (like in the lowering phase of a bench press). If the force is too great, the tendon can fail, meaning it starts to detach from the bone. People often feel a popping or tearing sensation when this happens.

It is critical to treat pectoralis major tendon tears because they can be extremely painful and can significantly reduce a person’s use of their shoulder. If left untreated, people with this injury may go on to have significant weakness. Since most injuries occur in athletes, it is vital to help preserve their strength.

How treatment is performed

Pectoralis repair surgery is done for tendons that have completely ruptured from the bone. Surgery is often preferred over nonoperative care for athletes as well as young, active people.

For this surgery, a cut is made above the armpit, the edge of the ruptured tendon is located, and stitches (sutures) are passed through the end of the tendon so that it can be pulled toward the arm bone. Small holes are drilled in the arm bone to allow anchors to be inserted. The anchors are loaded with strong non-absorbable sutures. The sutures are then passed through the torn tendon using a “tension-slide” technique. One piece of the suture is left outside of the tendon, so the surgeon can pull on it to bring the tendon directly down to its insertion site on the bone. In rare circumstances, donor tendons or tissues are required to lengthen the tendon enough so it can be reattached to the bone. These surgical techniques are also used to repair latissimus tendon tears.

Risks and benefits

As with many surgeries, the risks of pectoralis major tendon surgery include:

  • Weakness or stiffness following surgery
  • A recurrent pectoral tendon rupture
  • Risks of anesthesia
  • Infection
  • Nerve or blood vessel injuries
  • Cosmetic deformity with a change of the appearance of the pectoralis major muscle

However, the overall risk of surgery is very low, and it’s essential that pectoralis major tendon tears are treated as soon as possible to reach full recovery. The benefits of the surgery far outweigh the risks for most people.

The estimated time for full recovery from surgery is six months.

Physical therapy protocols

Pectoralis Major Tendon Repair

After surgery, a sling is worn for six weeks. Physical therapy then begins, starting with range-of-motion exercises and progressing to light strengthening exercises. Strengthening of the pectoralis muscle begins twelve weeks after surgery.

Pain control

People often experience some pain after surgery, but the pain generally improves after the second day. Pain can be managed with:

  • Cold therapy (e.g., ice or commercial cold therapy unit)
  • Sleeping in an upright position
  • Oral pain medications

Recovery time

The estimated time for full recovery from surgery is six months, although continued work on motion and strength allows people to see improvements for up to one year after surgery. See Dr. Romeo’s 2021 paper Return to Work After Pectoralis Major Repair for more info.


Those who undergo pectoralis major tendon repair surgery generally experience positive outcomes. Most patients are able to regain almost all of their baseline function after surgery, including the ability to return to their sporting activities.


How is a pectoralis major tendon tear diagnosed?

Pectoralis major tendon tears can often be identified through a physical examination. The affected arm and chest are often swollen and bruised. A common sign found in people with a pectoralis major tendon tear is called the “dropped nipple” sign. This occurs when the nipple on the side with the tendon tear appears a few inches lower than the other nipple. To confirm the injury, a physician will usually request an MRI or ultrasound.
