Скачать или смотреть Bone growth In Children - Everything You Need To Know - Dr. Nabil Ebraheim

Dr. Ebraheim’s educational animated video describes the long bone growth in children.
The epiphyseal contribution of long bone growth:
Humerus
•Proximal 80%
•Distal 20%
•Displaced fractures of the proximal humerus in children are usually treated without surgery.
Ulna/radius
•Proximal 80%
•Distal 20%
•Growth arrest is common in fractures involving the distal ulnar approximately 50%.
Radius
•Proximal 25%
•Distal 75%
•Fractures at the distal radius usually heal and correct it angulation after closed reduction-rarely surgery is needed. A fracture involving the growth pate of the distal radius rarely involves growth arrest.
Femur
•Proximal 30%
•Distal 70%
•Fractures involving the growth plate of the distal femur may cause major growth disturbances. It is expected that a child grows 1 cm per year from the distal femur growth plate. Boys grow up till 16 years old. Girls grow up till 14 years old.
Tibia
•Proximal 55%
•Distal 45%
Fibula proximal 60%
•Distal 40%
A growth spurt occurs at the time of puberty. Puberty typically occurs from 8-13 years of age in girls and from 10-15 years of age in boys. Fractures near the growth plate remodel well.
