Infrahyoid Muscle Sprains

An infrahyoid muscle sprain is an injury that occurs when the muscles located below the hyoid bone (in the front of the neck) are overstretched or torn. These muscles—which include the sternohyoid, omohyoid, sternothyroid, and thyrohyoid—help stabilize the hyoid bone and support essential functions like swallowing and speaking. When these muscles are sprained, you may experience pain, discomfort, and reduced mobility in the neck. This article reviews evidence-based details on what the injury involves and offers practical guidance on diagnosis, treatment, and prevention.


Anatomy of the Infrahyoid Muscles

Understanding the structure and function of the infrahyoid muscles is crucial to grasping how a sprain affects them. Below, we explain the anatomy in plain language.

Structure and Location

The infrahyoid muscles are a group of four paired muscles located in the front of the neck, below the hyoid bone. They play an important role in neck movement and in stabilizing the hyoid bone during swallowing and speech.

Origin and Insertion

  • Sternohyoid Muscle

    • Origin: The manubrium of the sternum and the medial end of the clavicle.

    • Insertion: The body of the hyoid bone.

  • Omohyoid Muscle

    • Origin: The superior border of the scapula (shoulder blade).

    • Insertion: The lower border of the hyoid bone via an intermediate tendon.

  • Sternothyroid Muscle

    • Origin: The manubrium of the sternum.

    • Insertion: The thyroid cartilage of the larynx.

  • Thyrohyoid Muscle

    • Origin: The thyroid cartilage.

    • Insertion: The hyoid bone.

Blood Supply

The blood supply to these muscles primarily comes from small branches of the:

  • Thyrocervical trunk (a branch of the subclavian artery)

  • Ascending cervical arteries
    These blood vessels ensure that the muscles receive the oxygen and nutrients necessary for repair and proper function.

Nerve Supply

The infrahyoid muscles are mainly controlled by:

  • The ansa cervicalis, a loop of nerves that comes from the cervical spinal nerves.

  • In some cases, additional nerve fibers from the vagus nerve may contribute.

Main Functions of the Infrahyoid Muscles

  1. Stabilization of the Hyoid Bone: They keep the hyoid bone in place during swallowing and speech.

  2. Assisting in Swallowing: These muscles help pull the hyoid bone downward to facilitate safe swallowing.

  3. Speech Production: They contribute to controlling the tension of the laryngeal muscles, which is important for sound modulation.

  4. Neck Movement: They assist with small movements of the neck and help maintain posture.

  5. Respiratory Support: By stabilizing the hyoid, they indirectly support the airway during breathing.

  6. Protection of Vital Structures: They help shield the airway and upper digestive tract by maintaining the position of the hyoid bone.


Types of Infrahyoid Muscle Sprains

Like other muscle sprains, infrahyoid muscle sprains are classified based on severity and the nature of the injury. While not all sprains in the neck region are widely categorized into subtypes, for practical purposes, they can be described as follows:

  1. Mild Sprain:

    • Slight stretching or micro-tears in the muscle fibers.

    • Minimal pain and tenderness.

    • Usually heals with rest and simple measures.

  2. Moderate Sprain:

    • More noticeable tearing of muscle fibers.

    • Increased pain, swelling, and limited movement.

    • May require physical therapy along with rest.

  3. Severe Sprain:

    • Significant tearing or rupture of the muscle fibers.

    • Severe pain, considerable swelling, and pronounced functional limitations.

    • Often requires intensive treatment, possibly including surgery.

  4. Acute vs. Chronic Sprains:

    • Acute Sprain: Injury that happens suddenly, often due to a sudden force or trauma.

    • Chronic Sprain: Ongoing muscle strain due to repetitive stress or untreated injuries.


Common Causes of Infrahyoid Muscle Sprain

Here are twenty possible causes or risk factors associated with infrahyoid muscle sprains:

  1. Trauma from an accident (e.g., motor vehicle accident).

  2. Sports injuries due to sudden impact or collision.

  3. Falls leading to abrupt neck movement.

  4. Whiplash injuries from rapid forward and backward motion.

  5. Overuse from repetitive motions or strain.

  6. Heavy lifting with improper technique.

  7. Sudden twisting movements of the neck.

  8. Direct blows to the front of the neck.

  9. Work-related injuries in physically demanding jobs.

  10. Strains during physical exercise without proper warm-up.

  11. Improper posture that puts extra stress on the neck.

  12. Stress and tension in the neck muscles.

  13. Accidents during contact sports (e.g., football, hockey).

  14. Violence or assault resulting in blunt trauma.

  15. Medical procedures that inadvertently strain the neck.

  16. Repetitive tasks in professions like dentistry or office work.

  17. Sudden jerking motions from unexpected movements.

Frequently Asked Questions (FAQs)

  1. What is an infrahyoid muscle sprain?
    It is an injury to the muscles beneath the hyoid bone, often caused by overstretching or tearing during sudden movements or trauma.

  2. How does a sprain differ from a strain in these muscles?
    A sprain typically refers to ligament injuries, while a strain involves muscle fibers. In this context, “sprain” is used to describe an injury to the muscle itself.

  3. What are the common symptoms?
    Symptoms include neck pain, stiffness, swelling, limited movement, and sometimes difficulty swallowing or speaking.

  4. How can I prevent such an injury?
    Warming up before exercise, maintaining good posture, and using proper techniques during activities can help prevent injury.

  5. What are the initial treatment steps?
    Begin with rest, ice, gentle stretching, and avoiding aggravating activities. A healthcare professional may recommend physical therapy.

  6. When should I consider using medication?
    If pain and inflammation persist, over-the-counter NSAIDs or prescribed medications may be used after consulting with your doctor.

  7. Is surgery often required?
    Surgery is rare for this type of injury and is reserved for severe cases with significant muscle damage.

  8. Can physical therapy help?
    Yes, physical therapy is one of the most effective treatments, helping to restore range of motion and strength.

  9. What diagnostic tests are most helpful?
    A physical exam, ultrasound, and MRI are commonly used to assess the injury’s extent.

  10. Are there home remedies that can help?
    Yes—using ice or heat, gentle stretching, and self-massage are popular home remedies.

  11. How long does recovery usually take?
    Recovery can range from a few days for a mild injury to several weeks or longer for more severe sprains.

  12. Can I return to exercise after a sprain?
    It is best to gradually return to exercise under the guidance of a professional.

  13. What role does posture play in prevention?
    Good posture reduces strain on the neck muscles, lowering the risk of injury.

  14. Are there any long-term complications?
    With proper treatment, most people recover fully; however, untreated injuries might lead to chronic pain or reduced neck mobility.

  15. Where can I find more information?
    Trusted sources include healthcare provider websites, medical journals, and organizations specializing in musculoskeletal health.


Conclusion

An infrahyoid muscle sprain, although less common than other neck injuries, can affect your ability to swallow, speak, and move your neck freely. By understanding the anatomy, knowing the causes, recognizing the symptoms, and being aware of the available diagnostic tests and treatments, you can manage this condition effectively. Always follow evidence-based practices and consult healthcare professionals if symptoms worsen or do not improve. With proper care and preventive measures, most individuals can fully recover and return to their daily activities with improved neck function.
