What is a pectoralis tear?
A pectoralis tear is an injury to the pectoralis major muscle or its tendon, located in the chest and attached to the upper arm. Tears can range from mild strains to complete ruptures, often occurring during forceful or heavy upper-body movements.
Causes of pectoralis tear
This injury typically occurs during high-intensity activities that involve pushing or heavy lifting, especially when the arm is extended or under load. It can also result from trauma or sudden force applied to the chest or arm.
Risk factors for pectoralis tear
- Heavy weightlifting (especially bench pressing)
- Contact sports such as football, wrestling, or rugby
- Poor lifting technique or lack of warm-up
- Use of anabolic steroids
- Previous chest or shoulder injuries
Symptoms of pectoralis tear
- Sudden sharp pain in the chest, shoulder, or upper arm
- Swelling, bruising, or a visible defect in the chest muscle
- Weakness or difficulty with pushing motions
- Popping or tearing sensation at the time of injury
- Limited range of motion or decreased strength
Diagnosing pectoralis tear
Diagnosis is based on physical exam findings, such as muscle deformity and weakness in the chest or arm. MRI is typically used to confirm the extent and location of the tear.
Treatment of pectoralis tear
Treatment depends on the severity of the tear. Partial tears may be treated with rest, physical therapy, and anti-inflammatory medications, while complete tears often require surgical repair.
