Infant neck injuries refer to harm affecting a newborn’s neck during labor, delivery, or immediately after birth. A birth injury involves physical damage that occurs in the process of childbirth.
In the case of infant neck injuries, harm may involve muscles, bones, nerves, or soft tissues located in the neck region.
Muscles can become strained or torn. Bones in the cervical spine may experience stress. Nerves that extend into the shoulders and arms can be stretched.
Soft tissues can develop swelling or bruising. Each of these issues falls under the broader category of infant neck injuries.

Types of Neck Injuries to Watch For
Infant neck injuries vary in severity. Some resolve with minimal intervention. Others require structured treatment and long-term monitoring.
Careful observation during the newborn period helps identify patterns that fit specific injury types.
Congenital Muscular Torticollis
Congenital muscular torticollis occurs when a neck muscle becomes tight or injured.
Sternocleidomastoid muscle involvement is common. Tightness causes the baby’s head to tilt to one side and rotate toward the opposite side.
Positioning in the womb may lead to persistent shortening of the muscle. Trauma during delivery can damage muscle fibers and result in swelling or thickening within the muscle.
- Consistent head tilt to one side
- Limited ability to rotate the head in one direction
- Preference for looking toward one side
Early stretching exercises and guided physical therapy can gradually improve alignment and flexibility.
Soft Tissue Injury
Soft tissue injury involves bruising or swelling in the neck or shoulder area.
Mild swelling can appear after a normal vaginal delivery due to pressure. Significant swelling or marked discoloration may suggest trauma.
- Firm swelling near the base of the neck
- Expanding bruising over the shoulder region
- Tenderness during gentle handling
Observation during the first few days is essential. Persistent swelling or increasing discoloration requires medical evaluation to rule out deeper injury.
Nerve-Related Injuries
Infant neck injuries may involve damage to nerves that extend into the shoulder and arm. Brachial plexus injury occurs when nerve roots are stretched during birth.
Excessive traction can disrupt nerve signals that control arm movement.
- Reduced the spontaneous movement of one arm
- Weak grip on one side
- Limited shoulder motion compared to the opposite side
Severity varies. Some cases improve with time and therapy. More significant nerve injury may require specialist evaluation and long-term rehabilitation.
@midwifemarley Erbs palsy occurs in around 1-2 in 1000 births. Most babies recover fully with early intervention. The tone of a newborn is something that midwives will look at immediately after the birth and in most cases, Erbs palsy is identified very quickly. #newborn #erbspalsy #birthtrauma #midwife #midwifery ♬ original sound – Midwife Marley
Spinal Cord Injury
Spinal cord injury in the neck is rare but serious.
Direct trauma to the cervical spine can interfere with nerve transmission throughout the body.
- Marked weakness in multiple limbs
- Poor muscle tone
- Abnormal breathing patterns
Immediate medical attention is critical if spinal cord involvement is suspected. Rapid assessment can be life-saving.
Signs and Symptoms in the First Few Days
Early recognition of infant neck injuries depends on careful daily observation. Subtle patterns often become clearer during feeding, diaper changes, and routine handling.
Physical and Movement Signs
Careful observation of posture and spontaneous movement during the first days of life can reveal early clues of infant neck injuries. Newborns naturally move their heads in response to sound, touch, and changes in position.
Repeated patterns of asymmetry or resistance to motion may signal a problem that requires evaluation.
Head Tilt or Asymmetry
Persistent head tilt to one side may indicate muscular torticollis or another form of infant neck injury.
The head may appear angled consistently in the same direction during sleep, feeding, and alert periods. Uneven positioning that does not correct with gentle repositioning deserves evaluation.
Caregivers may notice that the baby prefers looking in one direction and resists turning the head the opposite way. Limited correction despite calm handling suggests muscle tightness or structural restriction.
Early recognition helps prevent secondary issues such as positional head flattening.
Limited Neck Movement or Stiffness
Reduced ability to turn the head or visible discomfort during movement can signal muscle tightness or injury.
Healthy newborns usually rotate their heads to both sides when stimulated or repositioned. Persistent stiffness is not typical.
Infant neck injuries involving muscle strain can limit flexibility.
In more serious cases, deeper tissue or nerve involvement may contribute to decreased movement. Stiffness that remains consistent over several days should prompt medical assessment.

Visible Bruising or Swelling
Noticeable bruising around the neck or shoulder, especially if extensive, may point to soft tissue trauma. Mild discoloration can occur after vaginal delivery due to pressure.
More significant findings deserve attention. Swelling that enlarges, feels hard, or interferes with movement requires medical review.
Monitoring changes in size, color, and sensitivity during the first few days is important when infant neck injuries are suspected. Early evaluation can determine if imaging or specialist referral is needed.
Functional Signs
Feeding often reveals early problems linked to infant neck injuries. Discomfort or restricted motion can interfere with effective positioning.
- Difficulty latching on one side
- Preference for feeding in one direction only
- Fussiness during attempts to reposition the head
Excessive crying when caregivers move or touch the neck may indicate pain. Sensitivity during routine care, such as dressing or burping can signal injury.
Neurological and Associated Findings
Limited movement or weakness in one arm can suggest nerve involvement related to infant neck injuries. Comparison of both sides is important during observation.
Reduced spontaneous motion on one side should prompt evaluation.
Marked lethargy or decreased responsiveness may signal significant trauma. Changes in breathing, feeding, or responsiveness require immediate medical assessment.
Why Early Identification Matters
Infant neck injuries are not always obvious in the hours after birth.
Newborns often sleep for long periods and have limited voluntary movement, which can make early signs easy to miss.
Subtle stiffness or mild asymmetry may not attract attention right away.
Over the next several days, patterns may become clearer as caregivers handle, feed, and reposition the baby more frequently.
Delayed recognition can postpone important care. Untreated muscle tightness may worsen.
Nerve-related weakness can become more noticeable as normal movement increases. In some cases, delayed care may lead to secondary concerns such as positional head flattening or feeding problems.
- Careful observation of head posture at rest
- Gentle evaluation of the neck range of motion
- Comparison of arm movement on both sides
- Assessment of muscle tone and newborn reflexes
Prompt action supports early therapy and structured monitoring.
Physical therapy for muscular causes of infant neck injuries is often most effective when started early.
Close follow-up can detect improvement or signal a need for additional testing. Timely care reduces complications and supports healthy growth and motor development.
How Neck Injuries Happen During Birth
Infant neck injuries can occur during the physical stress of labor and delivery. Passage through the birth canal places pressure on the head, neck, and shoulders.
Most babies tolerate this process well, yet certain conditions increase vulnerability.
Common Causes of Birth Trauma
Difficult or prolonged labor increases the chance of strain to the neck.
Extended pressure on the baby’s body can stretch muscles and connective tissues. Forceful delivery maneuvers may also contribute to injury.
- Excessive traction is applied to assist delivery
- Rapid pulling or twisting motions of the head and shoulders
- Compression of the neck during passage through the birth canal
Each of these forces can affect soft tissues, muscles, or nerves in the cervical region. Greater force and longer duration of stress raise the likelihood of injury.
Risk Factors
Certain conditions make infant neck injuries more likely. Abnormal fetal positioning, such as breech or shoulder presentation, increases stress on the neck and shoulder region during delivery.
Larger fetal size can create additional strain as the baby passes through the birth canal.
Assisted deliveries using forceps or vacuum devices may also increase pressure or traction on the baby’s neck.
Risk may increase if traction is significant or positioning is suboptimal.
- Prolonged second stage of labor
- Shoulder dystocia
- Maternal pelvic size that limits the space during delivery
The presence of one or more of these factors does not guarantee injury, yet combined stress can raise concern for infant neck injuries.
