こどもの骨折の治療

Trauma is the major cause of morbidity and mortality among children. Since the mid 1930’s, trauma has been the leading cause of death in persons from 1 to 44 years of age, far exceeding death from infections. In those younger than 35 years, morbidity and mortality resulting from injury far exceeds that from cancer and heart disease. Fractures in children differ from those in adults in several ways : ( 1 ) Bone healing is very rapid in childhood because of the thickened periosteum and abundant blood supply. ( 2 ) Accurate anatomic reduction is less important than in the adult because malunited fragments are realigned spontaneously by active bone remodeling. ( 3 ) Injuries involving the physis may produce growth disturbance with/without angular deformity. ( 4 ) Fractures through the diaphysis or metaphysis stimulate longitudinal overgrowth of the bone.
