Sternothyroid muscle tears are injuries involving one of the small but important muscles in your neck. Although not as common as injuries to larger muscles, tears in this muscle can cause significant discomfort and functional limitations.
Anatomy of the Sternothyroid Muscle
Understanding the anatomy of the sternothyroid muscle helps explain why injuries occur and how they affect neck function. Below are the key anatomical details:
Structure & Location
-
Location: The sternothyroid is one of the strap muscles in the front of your neck. It lies between the sternum (breastbone) and the thyroid cartilage (a part of your voice box).
-
Structure: It is a thin, flat muscle that contributes to the movement and stabilization of the neck.
Origin and Insertion
-
Origin: The muscle starts from the manubrium of the sternum (the upper part of the breastbone).
-
Insertion: It attaches to the thyroid cartilage of the larynx.
Blood Supply
-
Primary Blood Vessels: The sternothyroid muscle is mainly supplied by branches of the superior thyroid artery. In some cases, the inferior thyroid artery may also contribute.
Nerve Supply
-
Innervation: The muscle is innervated by the ansa cervicalis, a loop of nerves formed from the cervical plexus, which helps control its movements.
Key Functions
-
Depressing the Thyroid Cartilage: Helps lower the larynx, which is important during swallowing and speaking.
-
Stabilizing the Neck: Provides support to keep the neck muscles in balance.
-
Assisting in Swallowing: Works in coordination with other muscles to move food and liquids down the throat.
-
Aiding in Phonation: Contributes to voice modulation by controlling the position of the larynx.
-
Protecting Airway Structures: Helps maintain the proper alignment of the neck during head movements.
-
Supporting Posture: Plays a minor role in keeping the head upright.
Types of Sternothyroid Muscle Tears
Sternothyroid muscle tears can vary in severity and presentation. They are generally classified based on the extent of the muscle damage and the nature of the injury:
-
Grade I – Mild Strain:
Tiny tears in the muscle fibers without significant loss of strength or function. -
Grade II – Partial Tear:
A more significant injury where some muscle fibers are torn, leading to moderate pain and weakness. -
Grade III – Complete Tear:
A severe injury with a complete rupture of the muscle. This type may require surgical intervention if other neck structures are involved. -
Acute Tears:
These occur suddenly following an injury or trauma (e.g., sports injury, accident). -
Chronic Tears:
These develop over time due to repetitive strain or long-term overuse of the muscle.
Causes of Sternothyroid Muscle Tears
Here is a list of 20 potential causes for sternothyroid muscle tears. These causes range from direct trauma to repetitive strain:
-
Direct Trauma: A blunt force hit directly to the neck.
