Unformatted text preview: Principles of management Pediatric Fractures Mamoun Kremli Riyadh, Saudi Arabia Orthokids International Symposium Riyadh, 2007 مممممم مممممم مممم ممم Objectives • Statistics about fractures in children • How children’s bones are different • Outline principles of management • Point out specific precautions Acknowledgement and recommendation Lynn T Staheli introduction • In Middle East ~60% of population are < 20 yrs. • Fractures account for ~15% of all injuries in children. • Different from adult fractures • Vary in various age groups ( Infants, children, adolescents ) Statistics • ~ 50% of boys and 25% of girls, expected to have a fracture during childhood. • Boys > girls • Rate increases with age. Mizulta, 1987 Statistics • ~ 50% of boys and 25% of girls, expected to have a fracture during childhood. • Boys > girls • Rate increases with age. • Physeal injuries with age. Mizulta, 1987 Statistics Most frequent sites (sample of 923 children, Mizulta, 1987) Why are children’s fractures different? Children have different physiology and anatomy • Growth plate. • Bone. • Cartilage. • Periosteum. • Ligaments. • Age-related • physiology Why are children’s fractures different? Children have different physiology and anatomy • Growth plate: – In infants, GP is stronger than bone increased diaphyseal fractures – Provides perfect remodeling power. – Injury of growth plate causes deformity. – A fracture might lead to overgrowth. Why are children’s fractures different? Children have different physiology and anatomy • Bone: – Increased collagen: bone ratio - lowers modulus of elasticity Why are children’s fractures different? Children have different physiology and anatomy • Bone: – Increased collagen: bone ratio - lowers modulus of elasticity – Increased cancellous bone - reduces tensile strength - reduces tendency of fracture to propagate less comminuted fractures – Bone fails on both tension and compression - commonly seen “buckle” fracture Why are children’s fractures different?Why are children’s fractures different?...
