Small lesion-high risk: diagnostic performance of artificial intelligence in paediatric fractures with medicolegal impact
This study evaluated the diagnostic performance of a CE-certified AI-based software (SmartUrgence) in detecting four types of medicolegally relevant paediatric fractures: lateral humeral condyle, Monteggia, trampoline proximal tibia, and medial malleolar fractures. The AI system demonstrated high specificity across all regions and strong sensitivity for most fracture types, notably 100% for trampoline fractures. However, it exhibited a significant limitation in detecting radial head dislocations associated with Monteggia fractures, achieving only 2% sensitivity. The study highlights the potential of AI as a second reader but emphasizes the need for enhanced sensitivity in high-risk, subtle injuries, particularly elbow dislocations.

Sensitivity for Monteggia Radial Head Dislocations
The AI system demonstrated a critical limitation by identifying only 1 out of 52 radial head dislocations associated with Monteggia fractures, yielding a sensitivity of just 2%. This highlights a significant area for improvement.

Performance Assessment
The Monteggia Challenge: A Critical Miss
The study revealed a significant challenge in AI detection of Monteggia fractures. While ulnar fractures were detected with 81% sensitivity, the critical associated radial head dislocations were identified in only 2% of cases. This represents a major medicolegal risk, as persistent radial head dislocation can lead to severe long-term complications. The AI system's misclassification of elbow images as 'forearm' views likely contributed to this failure. This highlights the need for targeted AI training on subtle, high-stakes injuries.
