The scalenus medius muscle is one of the key muscles in your neck. When this muscle is strained, you may experience pain, stiffness, or even nerve-related symptoms. Whether you are an active individual or work at a desk, understanding scalenus medius muscle strain is important.
Anatomy of the Scalenus Medius Muscle
Understanding the basics of the muscle’s anatomy helps explain why strains occur and how they can affect your overall neck function.
Structure & Location
-
Where It Is:
The scalenus medius muscle is located on the side of your neck. It lies deep under other neck muscles and reaches from the spine to the upper rib. It forms part of a group called the scalene muscles that also include the scalenus anterior and scalenus posterior.
Origin and Insertion
-
Origin:
The muscle originates from the transverse (side) processes of several cervical vertebrae (small bones in your neck). -
Insertion:
The muscle attaches to the first rib (the topmost rib). This position makes it important for both neck movement and assisting in breathing.
Blood Supply
-
Main Blood Vessels:
The scalenus medius receives blood from small branches (such as those from the ascending cervical artery and thyrocervical trunk) that supply oxygen and nutrients to the muscle.
Nerve Supply
-
Nerves Involved:
The muscle is innervated by branches from the cervical spinal nerves. These nerves help send signals to the muscle for movement and feeling.
Key Functions
-
Neck Movement:
Helps you bend (flex) your neck. -
Side Bending:
Assists in leaning your head to the side. -
Neck Rotation:
Plays a role in turning your head. -
Breathing Support:
Helps raise the first rib during deep breaths, especially during forceful inspiration. -
Stabilization:
Aids in maintaining the alignment of your cervical spine (neck). -
Postural Support:
Contributes to keeping your head and neck in a proper position during daily activities.
Types of Scalenus Medius Muscle Strain
Muscle strains are typically categorized by how severe the injury is or by the nature of the injury. For the scalenus medius, common types include:
-
Acute Strain:
A sudden tear or overstretching, often due to a specific injury or trauma. -
Chronic Strain:
Ongoing or repetitive stress to the muscle that leads to continuous strain over time. -
Repetitive Overuse Strain:
Develops slowly from repeated actions—such as prolonged desk work or sports with repetitive neck movements. -
Traumatic Strain:
Resulting from an accident or forceful impact like in a car accident or a fall.

Surgical Options for Scalenus Medius Muscle Strain
In most cases, a scalenus medius muscle strain is managed with conservative treatments. However, surgery might be considered when severe complications or nerve compressions occur (such as in thoracic outlet syndrome). Here are 10 surgical options or procedures related to such cases:
-
Scalenectomy: Surgical removal or release of part of the scalenus muscle to relieve nerve compression.

Neurolysis: Removing scar tissue or other structures that compress the nerves.
-
Thoracic Outlet Decompression: A procedure designed to relieve compression of the nerves and blood vessels between the collarbone and first rib.
-
Resection of Fibrous Bands: Removing tight bands that may compress nerves.
-
Minimally Invasive Endoscopic Scalenectomy: A less-invasive procedure to release the muscle.
-
Open Scalenectomy: A traditional surgical approach to remove or release part of the muscle.
-
Posterior Cervical Decompression: Decompression in the back of the neck if multiple structures are involved.
-
Combined Procedures: In complex cases, surgeons may combine several techniques (for example, a scalenectomy with rib resection) to relieve symptoms.
Note: Surgery is considered only after other treatments have failed, and the exact procedure depends on each patient’s condition.
