Overview
The pectoralis major drives pushing, bench-pressing, and horizontal adduction of the arm. Ruptures almost always occur at the humeral attachment, typically during heavy eccentric loading — the descent of a bench press is the classic scenario. Without repair, the muscle retracts, push strength is lost, and the contour of the chest is visibly altered.
How the Procedure Works
We retrieve the retracted tendon through a deltopectoral incision, prepare it with heavy locking sutures, and reattach it to the humeral footprint — a broad insertion along the lateral lip of the bicipital groove that is easy to under-restore if the repair is placed too anteriorly. Transosseous tunnels through the humerus are our preference for fixation strength; suture anchors are an alternative when bone quality or geometry makes tunnels impractical. The key intraoperative check is tension: the repaired tendon should lie flat against bone with the arm in slight adduction and internal rotation, and the chest contour should be symmetric. Acute repair produces reliably better strength recovery than delayed repair; in the delayed setting, scarring and muscle retraction require more dissection and the tissue quality is often degraded.
When to Consider Pectoralis Major Repair
Pectoralis major repair is generally offered when symptoms, imaging, and a trial of non-operative care together point to surgery as the next step. The typical picture includes:
Acute pec major rupture
A sudden tear, typically in a weight-training athlete, with a palpable defect and bruising in the axilla.
Chronic rupture with functional loss
An older rupture with persistent weakness or cosmetic concern that the patient wants addressed.

Risks & Why We Still Recommend It
Every operation carries risk. The reason we offer this procedure is that the condition, left untreated, causes persistent weakness in pressing and adduction, an obvious contour deformity, and a functional deficit that matters in heavy lifters and athletes. That is the trade we are managing — not eliminating risk, but choosing the smaller of two unfavorable trajectories.
The risks we discuss with patients before pectoralis major repair include:
- bleeding and infection
- anesthesia risk
- hematoma (the pec territory bleeds)
- re-rupture, particularly with early heavy loading
- suture-anchor or cortical-button irritation
- residual asymmetry
- transient brachial plexus irritation from positioning
The indication to proceed is an acute pectoralis major rupture in a patient who relies on pressing strength. Patients who don't need this operation don't get it.
