Pectoralis Major Rupture
Pectoralis Major Rupture (Pec Tear)
Also known as the ‘pec’, the pectoralis major muscle is large muscle that is located on the chest wall across the upper chest. This large muscle makes up the bulk of the chest muscles and lies just under the breast stretching across the collarbone (clavicle) to the breastbone (sternum).
The pectoralis major is an important muscle and plays an essential role in shoulder function by rotating the joint towards the body (providing internal rotation) and bringing the arm towards the body (adduction). Injury to this powerful muscle can occur during heavy lifting activities that requires contraction.
Strains (tears) and ruptures of the pectoralis major muscle occur due to heavy weightlifting (bench pressing). This muscle is critical for maximum strength in athletes, labor intensive workers, and active individuals. Pectoralis major injuries mostly occur suddenly whilst working with high intensity.
The injury is usually felt as a painful snapping sensation at the front of the chest and shoulder. This leads to a painful upper arm and chest, muscle deformity and weakness causing bruising and swelling.
Pectoral injury can also develop over time due to repetitive movements of certain muscles being used in specific activities such as CrossFit.
- Muscle spasm
- Muscle weakness
- Difficulty moving the area affected
- Injury to the nerve
- Continuous pain or weakness or both
- Blood clots or Hematoma
- Humerus or glenoid bone fracture
- Weakened bicep muscle
- Failed transfer
- SHIN BONE FRACTURE, often caused by a sudden physical injury, such as twisting.
- KNEE CAP FRACTURE, usually caused by a direct blow to the knee.
- THIGH BONE FRACTURE, in older people this is usually as a result of weak bones or in younger people, due to a high-energy impact.
