According to the International Year of Medicine statistics, the incidence of short stature caused by heredity and endocrinology is 43 per 10,000. At present, there are millions of such patients in our country and it is obviously a serious problem to improve the national physiological quality. My department treated 76 cases of idiopathic pituitary dwarfism, the following for its pathogenesis for a preliminary discussion and analysis. We conducted a special survey of 76 idiopathic pituitary dwarfism patients from the aspects of genetics, chromosomes, parentage, and mode of delivery, with no abnormalities found in the first three aspects, while the mode of delivery was mostly breech and partial horizontal Birth, standing production, 78% were born hypoxia, respiratory disorders, cyanosis and other production injury, and the arm, the position, high forceps in children, the incidence of pituitary dwarf higher. In our diagnosis and treatment of 76 cases of pituitary dwarfism in addition to 4 cases of unknown birth position, hip production (42 cases), horizontal in 4 cases, high forceps in 4 cases, accounting for 65.79% of the total, with foreign scholars Berich statistics Reported
