Sternohyoid Muscle Strain

A sternohyoid muscle strain occurs when the sternohyoid—a thin, flat muscle located in the front of your neck—gets overstretched or torn. This injury is similar to strains in other muscles and can result from sudden movements, overuse, or trauma. The strain may lead to pain, stiffness, and difficulty with normal neck movements. Although not a common injury compared to strains in larger muscles, it is important to know the details in case you experience neck discomfort.

Anatomy of the Sternohyoid Muscle

Structure and Location

• Location: The sternohyoid is one of the infrahyoid (below the hyoid bone) muscles in the neck. It runs along the front of the neck, close to the skin.

• Appearance: It is a thin, flat muscle that works together with other neck muscles to support the throat and assist in movements like swallowing.

Origin and Insertion

• Origin: The muscle begins (originates) at the back of the upper part of the sternum (manubrium) and sometimes from the first costal cartilage.

• Insertion: It attaches (inserts) onto the lower border of the hyoid bone—a small, U-shaped bone located in the front part of the neck.

Blood Supply

• Arterial Supply: The sternohyoid muscle typically receives blood from branches of the thyroid arteries. This ensures the muscle gets enough oxygen and nutrients.

Nerve Supply

• Innervation: The muscle is mainly supplied by nerves from the cervical plexus, particularly through the ansa cervicalis (a loop of nerves in the neck that comes from cervical spinal segments C1–C3).

Main Functions

1. Depression of the Hyoid Bone: Helps pull the hyoid bone downward.

2. Assistance with Swallowing: Works with other muscles to aid in swallowing.

3. Speech Support: Contributes to the positioning of the hyoid bone during speech.

4. Stabilizing the Neck: Supports the neck structure by keeping the hyoid bone in place.

5. Coordinated Neck Movement: Assists in smooth, controlled movement of the neck.

6. Laryngeal Positioning: Helps maintain proper position of the larynx (voice box) during various activities.

Types of Sternohyoid Muscle Strains

While sternohyoid muscle strain is not as common as injuries in larger muscles, strains can generally be classified into three grades:

• Grade I (Mild):
  Minor stretching with little to no tearing of muscle fibers. Pain and discomfort are usually mild.

• Grade II (Moderate):
  More muscle fibers are injured. This type usually causes moderate pain, swelling, and some loss of function.

• Grade III (Severe):
  A complete tear or major injury to the muscle. This is rare in small muscles like the sternohyoid and typically requires a longer recovery period.

In addition to these grades, strains may also be characterized by whether they occur suddenly (acute strain) or develop over time due to repetitive stress (chronic strain).

Causes of Sternohyoid Muscle Strain

A sternohyoid strain can result from many different activities and situations. Here are 20 potential causes:

1. Overuse in Speaking or Singing: Constant use can fatigue the muscle.

2. Trauma from Car Accidents: Sudden impact can injure neck muscles.

3. Sudden Twisting Movements: Rapid neck rotations may cause strain.

4. Poor Posture: Long-term slouching or forward head posture.

5. Heavy Lifting: Lifting heavy objects with improper technique.

6. Sports Injuries: Especially in contact sports or those involving rapid head movements.

7. Repetitive Neck Movements: Constant turning or tilting of the head.

8. Whiplash Injuries: Sudden forward and backward motion.

9. Muscle Fatigue: Overworking the neck muscles without adequate rest.

10. Stress and Tension: Physical tension from stress can affect muscle function.

11. Improper Exercise Form: Incorrect techniques during workouts.

12. Sudden Head Movement: Quick, unexpected movements.

13. Microtrauma: Small, repeated injuries that add up over time.

14. Heavy Manual Labor: Constant physical labor can lead to overuse.

15. Repetitive Strain Injuries: Due to continuous, repetitive tasks.

16. Neck Sprains: Often accompanying muscle strains.

17. Tension from Bruxism: Jaw clenching can transfer stress to neck muscles.

18. Cervical Spine Disorders: Underlying neck problems may predispose one to strain.
