The Claim

The tendon of the pectoralis major muscle exhibits a bilaminar anatomical structure consisting of anterior and posterior layers, and this structural organization may influence both the pattern of tendon tears and the surgical approaches required for repair.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

How it works
1 study reviewed
In plain English

The main chest muscle's tendon has two layers—one in front and one in back—and that might affect how it tears and how doctors fix it in surgery.

See the scientific wording

The tendon of the pectoralis major muscle has a bilaminar structure composed of anterior and posterior layers, which may influence how tears occur and how they are surgically repaired.

What the research says

1 study
  1. Study: Complete Rupture of the Pectoralis Major Tendon: Comparison of Magnetic Resonance Imaging and Intraoperative Images

    The study shows that the chest muscle tendon really does have two layers, which supports the idea that this structure could affect how it tears and is fixed in surgery.
