"Nursemaid's elbow" in infants six months and under

Area of Science:

• Pediatric Orthopedics
• Musculoskeletal Disorders
• Pediatric Trauma

Background:

• Nursemaid's elbow, also known as pulled elbow or subluxation of the radial head, is a common injury in young children.
• It typically occurs in children aged 1-4 years, resulting from sudden traction on the hand or forearm.
• Understanding the mechanisms of injury is crucial for accurate diagnosis and appropriate management.

Observation:

• This report details six cases of subluxation of the radial head in infants within the first six months of life.
• A significant observation is that in four of these cases, the injury was caused by a previously undocumented mechanism.
• The infants presented with specific clinical signs and symptoms consistent with radial head subluxation.

Findings:

• The study identifies six instances of nursemaid's elbow in a younger infant population than typically reported.
• Four cases demonstrated a novel mechanism of injury, expanding the known etiological factors for this condition.
• Radiographic findings were consistent with the clinical diagnosis of radial head subluxation.

Implications:

• These findings suggest that nursemaid's elbow may occur in younger infants than previously thought.
• The identification of new injury mechanisms necessitates a broader differential diagnosis and awareness among healthcare providers.
• This information can inform prevention strategies and improve the diagnostic accuracy for pulled elbow in infants.
