Nursemaid’s elbow, medically known as radial head subluxation, is one of the most common upper extremity injuries seen in young children. This injury occurs when a sudden pulling or tugging force is applied to a child’s arm, causing a bone in the elbow to partially slip out of place. It is particularly prevalent in children between the ages of one and four years old, a time when their anatomy makes them uniquely susceptible. While the injury can be painful and frightening for both the child and the caregiver, it is typically resolved quickly and without long-term consequences by a medical professional.
Understanding How the Injury Occurs
The biomechanical reason for this injury lies in the unique structure of a young child’s elbow joint. The elbow is composed of three bones: the humerus, the ulna, and the radius. The end of the radius, called the radial head, is held in its correct position by a band of connective tissue known as the annular ligament.
In toddlers and preschoolers, this annular ligament is generally thinner and looser compared to older children and adults because it has not yet fully matured or developed its full strength. When a sudden, sharp, or longitudinal pull is applied to the child’s hand or forearm, the radial head is pulled away from its socket. This force allows the delicate annular ligament to slip and become trapped between the radial head and the humerus bone. The trapped ligament prevents the radial head from returning to its normal position, resulting in the characteristic pain and refusal to use the arm. This mechanism is why the injury is also commonly referred to as a “pulled elbow.”
Specific Techniques for Prevention
The most effective strategy for prevention involves modifying how caregivers handle and interact with young children. A foundational rule is to consistently avoid any activity that applies a sudden, upward, or pulling force to the child’s hands or wrists.
When lifting a child, always support them by grasping them firmly under the armpits or around the chest and torso. Lifting a child by their hands or wrists, even gently, transmits traction force through the forearm and into the elbow joint, which can easily cause the radial head to subluxate. This practice should be avoided, particularly with children under five years old.
Caregivers should eliminate recreational activities that involve swinging the child by the arms, hands, or wrists. The centripetal force generated during swinging is a common cause of the injury. If a child enjoys being swung, hold them securely by the torso or upper body to distribute the force away from the elbow.
When dressing a child, take care not to yank or pull the arm through a jacket or sweater sleeve. Gently guide the garment over the hand and up the arm, minimizing forceful extension or twisting of the elbow. Teaching older siblings and other caretakers, such as grandparents or babysitters, these safe-handling practices ensures consistent prevention across all interactions.
When a child is resisting movement or throwing a tantrum, caregivers should use a firm but gentle grip on the child’s upper arm, near the shoulder, rather than holding the hand or wrist. This grip provides necessary control while protecting the elbow joint from traction.
Recognizing High-Risk Scenarios
Nursemaid’s elbow is frequently the result of common, everyday actions performed without awareness of the potential for injury. Situations where a child’s hand is grasped while their body lags or is positioned lower are particularly high-risk. This often occurs when walking with a child up or down stairs, curbs, or off a playground structure while holding their hand.
The injury can happen unexpectedly during moments of sudden stress or emergency. A caregiver’s instinct to grab a child’s hand to prevent a fall or quickly pull them out of danger, such as a moving car, can generate the necessary traction force. Even in these urgent situations, the safest practice is to grab the child around their upper body or torso if possible.
Other common scenarios include rough or boisterous play where the child’s arm is suddenly extended or jerked. Playful tugging or lifting a child onto a bed or sofa by their hands can be enough to cause the ligament to slip. Recognizing these moments of increased risk allows caregivers to proactively adjust their grip before a pulling force is inadvertently applied.
Immediate Steps After the Injury Happens
If a child sustains a Nursemaid’s elbow injury, they will typically begin crying immediately and refuse to use the injured arm, often holding it limp against their side with the elbow slightly bent. The arm may appear paralyzed, and the child will resist any attempt to move it because of the pain. The elbow joint usually does not show signs of swelling, bruising, or deformity.
It is crucial for caregivers to remain calm and avoid any attempt to manipulate or force the arm back into place themselves. Trying to reduce the subluxation without proper training risks causing further injury to the child’s arm. Immediate medical attention from a healthcare professional is necessary.
A trained practitioner can perform a simple, quick maneuver to guide the radial head and annular ligament back into their correct position. This procedure, known as a reduction, often provides the child with immediate pain relief and restores the use of the arm within minutes. Seeking prompt medical care is important, as it confirms the diagnosis and rules out other more serious injuries, such as a fracture.
