Pectoralis major tendon rupture
What is Pectoralis major tendon rupture?
A pectoralis major tendon rupture is a tear of the tendon that attaches the chest muscle to the upper arm bone. It most often occurs during heavy bench press, tackling, wrestling or sudden eccentric loading of the arm.
Common symptoms
Patients often feel a sudden pop or tearing sensation, followed by bruising, swelling, chest or upper arm pain, weakness with pushing and a change in the contour of the chest or anterior armpit fold.
Diagnosis and imaging
Diagnosis is based on the history, visible contour change, strength testing and palpation of the tendon. MRI is the most useful test to define whether the tear is partial or complete, how far the tendon has retracted and whether surgical repair is feasible.
Non-surgical treatment
Non-surgical treatment may be reasonable for partial tears, low-demand patients or chronic tears where function is acceptable. It involves pain control, gradual motion and progressive strengthening once symptoms settle.
Surgical treatment
Surgical repair is usually considered for complete tears in active patients, especially when strength, appearance and return to sport or gym training matter. Earlier repair is generally more straightforward because the tendon is easier to mobilise.
Recovery and follow-up
After repair, the shoulder is protected in a sling while the tendon heals. Motion and strengthening are introduced gradually. Heavy pressing and contact sport are delayed until tendon healing and strength recovery are advanced.
Pectoralis major tendon rupture FAQs
Why did the pectoralis tendon rupture?
The classic mechanism is heavy loading when the arm is extended and externally rotated, such as the lowering phase of a bench press. The tendon fails under sudden high tension.
How is pectoralis major tendon rupture diagnosed?
Diagnosis starts with a focused history and examination, then uses imaging selectively to confirm the pattern of injury, exclude related problems and plan treatment accurately.
Is surgery mainly cosmetic?
No. The contour change matters to some patients, but the main surgical goal is to restore strength, power and function for pushing, lifting and sport.
Will I need surgery for pectoralis major tendon rupture?
Many patients improve without surgery. Surgery is considered when symptoms remain limiting despite appropriate non-surgical care, when there is significant structural damage, or when delay may compromise function.
When can I return to bench press and contact sport?
Return depends on the diagnosis, treatment type, tissue healing and the physical demands of the activity. The plan is usually staged, with strength, range of motion and confidence rebuilt before unrestricted loading.
