Congress of Orthopedics
The twenty-third Congresso nazionale di ortopedia was held at Bologna, under the chairmanship of Professor Putti. A number of foreign surgeons were in attendance. In his address, Professor Putti brought out that the work of the congress would be based on observations in more than 4,000 cases of congenital dislocation of the hip, all of which had been reexamined radiologically at least three years after operation. He pointed out that the incidence of this abnormality amounts to about 2 per thousand of population. The chief speaker was Professor Annovazzi of Milan, who based his conclusions on 1,610 cases. In the children treated under 2 years of age, the percentage of good results was 82 per cent; in children under 5 and more than 2 years of age, 66 per cent, while in children more than 5 years old the percentage of favorable results diminished gradually.
