Symptoms of Nursemaid Elbow
A child with nursemaid's elbow typically presents with acute arm pain, refusal to use the affected arm (pseudoparalysis), and holds the arm in a characteristic position—semiflexed at the elbow and pronated at the forearm (the "nursemaid's position").
Classic Clinical Presentation
The hallmark symptoms include:
- Arm positioning: The child holds the affected arm close to the body, semiflexed at the elbow and pronated (palm down) 1
- Pseudoparalysis: Refusal or inability to use the arm, appearing as if the limb is paralyzed 2
- Pain: Acute-onset arm pain, though children are typically in minimal distress 1
- Limited range of motion: Particularly resistance to supination (turning palm up) and elbow extension
Mechanism and History
While the classic history involves axial traction on the arm (pulling the child by the wrist or hand), approximately one-third of cases present without this typical history 1. Common mechanisms include:
- Pulling or lifting the child by the wrist or hand
- Falls (44% of cases) 3
- Twisting motions
- The "vola-vola" game (swinging child by arms) 4
Important Clinical Caveats
Even without a classic traction history, nursemaid's elbow should be suspected in any child aged 1-4 years presenting with upper extremity pain and the characteristic arm positioning 1. The absence of a typical history should not exclude this diagnosis, as nonclassic presentations are common and can lead to misdiagnosis and delayed treatment.
The condition shows a female predominance (61.2%) and most commonly affects the left arm (63%) 5. Peak incidence occurs in children aged 0-3 years, with 2-year-olds representing the largest affected group 3.
Bilateral cases are exceedingly rare but have been reported, requiring broader differential diagnosis including spinal cord pathology 2. Recurrence occurs in approximately 4.8-14% of cases 5, 4.
