A scalenus posterior muscle sprain involves the stretching or tearing of the fibers of the scalenus posterior muscle, one of the muscles in the neck. This injury can lead to pain, decreased range of motion, and may even cause referred pain to other areas, such as the shoulder or arm.
Anatomy of the Scalenus Posterior Muscle
Understanding the anatomy is the first step in grasping the nature of a scalenus posterior muscle sprain. Here are the key details:
Structure and Location
-
Location: The scalenus posterior is part of the scalene muscle group located in the lateral aspect of the neck. It lies deep and is one of the three scalene muscles (anterior, middle, and posterior).
-
Structure: It is a slender, elongated muscle that runs from the cervical spine to the upper ribs, helping support the neck and assist in breathing.
Origin and Insertion
-
Origin: The scalenus posterior typically originates from the spinous processes of the upper thoracic vertebrae (often T1–T3) or the posterior tubercles of the transverse processes of the cervical vertebrae.
-
Insertion: It attaches to the upper surface of the second or third rib, allowing it to help with elevating the ribs during inspiration.
Blood Supply
-
Arterial Supply: The blood supply comes mainly from small branches of the vertebral artery and ascending cervical arteries. Good circulation is essential for muscle repair and recovery.
Nerve Supply
-
Innervation: The scalenus posterior is innervated by branches of the cervical nerves, often originating from the ventral rami of cervical spinal nerves, which coordinate the muscle’s movement and sensation.
Key Functions
-
Neck Stabilization: Helps stabilize the cervical spine during head movements.
-
Assisting Breathing: Elevates the upper ribs during deep inspiration, aiding in breathing.
-
Postural Support: Contributes to maintaining proper neck alignment and posture.
-
Lateral Flexion of the Neck: Assists in bending the neck to the side.
-
Rotation Assistance: Plays a minor role in rotating the head.
-
Protection of Neurovascular Structures: Helps in maintaining the space for important nerves and blood vessels that pass between the vertebrae and the upper ribs.
Types of Scalenus Posterior Muscle Sprains
Sprains of the scalenus posterior muscle can vary in severity and timing:
-
Acute Sprain: A sudden injury caused by trauma or excessive strain, resulting in immediate pain and functional loss.
-
Chronic or Overuse Sprain: Occurs due to repetitive stress or poor posture over time, leading to gradual onset of symptoms.
-
Partial Tear: In some cases, the injury may result in a partial tear of the muscle fibers, causing moderate pain and weakness.
-
Complete Tear: Although rare, a complete tear may occur with severe trauma and can lead to significant functional impairment.
-
Recurrent Sprain: With inadequate healing or persistent strain, the sprain may recur, often with increasing discomfort over time.
Common Causes of Scalenus Posterior Muscle Sprain
Scalenus posterior muscle sprains usually result from a combination of factors. Here are twenty common causes:
-
Sudden Trauma: Falls or accidents that jolt the neck.
-
Whiplash Injuries: Car accidents causing abrupt neck movements.
-
Sports Injuries: Contact sports or sudden, forceful impacts.
-
Heavy Lifting: Straining the neck muscles during improper lifting techniques.
