Vitamin D, rickets and child abuse: controversies and evidence

Area of Science:

• Pediatric Bone Health
• Nutritional Deficiencies
• Trauma and Injury

Background:

• Suboptimal vitamin D status is a widespread global health issue affecting all age groups.
• Vitamin D deficiency and insufficiency are prevalent in the pediatric population, particularly in the United States.
• Radiographic findings of vitamin D deficiency are uncommon and often subtle, despite the high prevalence of insufficiency.

Purpose of the Study:

• To review literature on bone disease in pediatric patients presenting with accidental and non-accidental trauma.
• To differentiate fractures caused by bone disease from those resulting from trauma in children.
• To aid physicians in identifying non-accidental trauma in vulnerable young children.

Main Methods:

• Literature review focusing on bone disease in the context of pediatric trauma.
• Analysis of fracture causes in infants and toddlers, distinguishing between trauma and medical conditions.
• Examination of the role of vitamin D deficiency and disorders of mineralization in pediatric fractures.

Main Results:

• The majority of pediatric fractures result from trauma to healthy bones, not underlying bone disease.
• While rickets can cause fractures, most fractures in abused infants are not due to bone disease.
• Non-rachitic disorders of vitamin D are a non-scientific theory used to explain fractures in abused children.

Conclusions:

• Physicians must remain vigilant in identifying non-accidental trauma in young children, as fractures are rarely caused by bone disease like vitamin D deficiency.
• Differentiating between trauma-induced fractures and those from medical conditions is crucial for accurate diagnosis and child protection.
• Understanding the nuances of pediatric bone health in trauma settings is essential for appropriate clinical management.
