Pectoralis Major Tendon Injury

Introduction

The pectoralis major tendon is responsible for the forward, backward and inward rotation. The tendon begins at the breastbone and the collarbone and connects to the upper arm bone in close proximity of the bicep tendon. Injury to this particular tendon is rare but can result in disability. 

This condition is most common in athletes involved in sports such as football, wrestling, skiing or weightlifting. More specifically, it can occur with any activity that models the movement of bench pressing. If the force working against the muscle is greater than what the muscle can create, the tendon can suffer injury. 

The condition creates pain in the arm and chest and can cause deformity and weakness. It usually occurs in men between the ages of 20-40.
