The Study
Complete Rupture of the Pectoralis Major Tendon: Comparison of Magnetic Resonance Imaging and Intraoperative Images
This study is like someone describing how a car engine looks without actually testing how it runs. It tells us about the parts of a muscle and tendon, but doesn’t show how well scans or surgery work to fix injuries.
Analysis score
Maximum 5 for a narrative review.
Where the score came from
The chest muscle has two parts: one on top connected to the collarbone and one below connected to the breastbone. The lower part is made of 6–7 chunks, and the muscle's rope-like tendon has two layers.

The big chest muscle has two parts: one on top with smooth, even fibers, and a lower part made of 6 or 7 separate bundles, where the bottom one folds forward.
Your chest muscle has two parts—one on top near your collarbone and one lower near your breastbone—and because they work a bit separately, it might affect how doctors fix injuries and how well you heal.
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.
