Fracture of the tuberosity of the ischium is comparatively rare. The only mention made of it by Scudder in the latest edition of his work is the statement that it is extremely rare. Stimpson mentions six cases collected by Malgaigne. Cotton in his recent book states he has no doubt that it may occur, and he has seen a number of cases in which that diagnosis had been made, but none in which it was justified.
—The patient, an Italian aged 23, three years before I saw him, while running in a race "felt something crack" in his left buttock, and fell forward to the ground. He was able to get up and walk, but there was severe pain and soreness in the left buttock. The acute symptoms gradually subsided, but pain, soreness and weakness persisted. The condition at last became so annoying that he decided to seek relief.
