Special Features of Fractures and Special Features of Fractures and Dislocation in ChildrenDislocation in Children
• 1. Fractures more common• 2. Stronger and more active periosteum • 3. More rapid fracture healing• 4. Special problems of diagnosis• 5. Spontaneous correction of certain residual deformities• 6. Differences in complications• 7. Different emphasis on methods of treatment• 8. Torn ligaments and dislocations less common• 9. Less tolerance of major blood loss
