Pectoralis Major Rupture
What is a Pectoralis Major Rupture?
A pectoralis major rupture is a tear of the pectoralis major muscle or tendon, often occurring during activities with heavy bench pressing or sudden forceful contractions.
- Tear in the chest muscle or tendon
- Causes chest and upper arm weakness
Overview of the Condition
Injuries can involve the muscle belly or, more commonly, the tendon near the humeral attachment. Common in weightlifters.
Symptoms
- Sudden chest pain during forceful pushing
- Bruising and swelling in chest or arm
- Weakness in adduction and internal rotation
Causes
Heavy bench press or traumatic stress on the pectoralis major can cause tendon or muscle fibers to tear.
Diagnosis
Physical exam may show a palpable gap in the muscle, asymmetry, or bruising. MRI helps confirm the tear site and severity.
Treatment Options
- Non-surgical management for partial tears or low-demand patients
- Surgical repair for complete tears in active individuals
- Physical therapy post-repair
Conservative Management
Rest, icing, and gradual return to activity. Accepting some strength deficit may be necessary for partial tears.
Rehabilitation Exercises
- Gentle range-of-motion initially
- Progress to light resistance exercises
- Rebuild chest and shoulder strength over months
Surgical Options
Reattachment of the tendon to the humerus using suture anchors or screws to restore normal strength in active patients.
Anatomy Overview
The pectoralis major has sternal and clavicular heads, inserting on the proximal humerus. Tears usually occur at the tendon near the humeral insertion.
Affected Areas
- Pectoralis major tendon near humerus
- Muscle belly (less common)
Frequently Asked Questions
| Question | Answer |
|---|---|
| Is surgery always required? | Active individuals often choose surgical repair for complete tears to regain full function. |
| How long before I can bench press again? | Typically 4-6 months post-surgery, depending on rehab progress. |
Prevention Strategies
- Use proper bench press technique
- Warm up thoroughly before heavy lifting
- Progress weight gradually to avoid tendon overload
