What are the types of pectoralis major tendon tears?
Pectoralis major tendon tears are classified into four categories based on the severity of the injury.
Type 1: The pectoralis major tendon is torn from the humerus. This is a common injury and is often surgically repaired.
Type 2: The area where the pectoralis major muscle meets the tendon, the musculotendinous junction, is torn or strained. This is also a common injury and often surgically repaired.
Type 3: The tear has occurred within the pectoralis major muscle belly, and the tendon remains fully intact.
Type 4: The pectoralis major tendon is torn from the sternocostal head.
