The furculum, or merry-thought, which is entire, marks the fore part of the trunk; the ischium, scapula, and most of the wing and leg bones are preserved, and there are impressions of the quill feathers and of down on the body. The vanes and shafts of the feathers can be seen by the naked eye.
The body of the ischium in this case was fractured and a rent in the bladder was caused by a sharp projecting piece of bone. Autopsy revealed, in addition to the fracture and rent of the bladder wall, a large quantity of urine in the peritoneal cavity. In other instances hemorrhage caused death and not infrequently infection was responsible for a fatal issue.
In females where the body of the ischium is fractured, lacerations of the vagina may be present, and this constitutes a serious complication which usually terminates fatally. After-care in fracture of the pelvic girdle consists principally in allowing a protracted period of rest before subjects are put to work. Fractures of the Femur. Etiology and Occurrence.
The pelvic bones approach the form of those of the birds, and the direction of the pubis and ischium is nearly that which is characteristic of birds; the thigh bone, from the direction of its head, must have lain close to the body; the tibia has a great crest; and, immovably fitted on to its lower end, there is a pulley-shaped bone, like that of the bird, but remaining distinct.

In the lower extremity, a large number of normal and adventitious bursæ are met with and may be the seat of bursitis. That over the tuberosity of the ischium, when enlarged as a trade disease, is known as "weaver's" or "tailor's bottom." It sometimes contains a number of loose bodies.

As quoted by Chelius, both Hennen and Cline relate cases in which men have been shot through the skirts of the jacket, the ball penetrating the abdomen above the tuberosity of the ischium, and entering the bladder, and the men have afterward urinated pieces of clothing, threads, etc., taken in by the ball.
THE PELVIS OR HAUNCH is formed by a single bone, the coxa that in the foetus may be divided into three bones. These are the ilium, pubis and ischium. It belongs to the class of flat bones. Anteriorly it is flattened from before to behind and directed inward and upward. The external angle is rugged and is generally termed the angle of the haunch.
The letters have the same signification in all the figures. Il., Ilium; a. anterior end; b. posterior end; Ia. ischium; Pb., pubis; T, tibia; F, fibula; As., astragalus; Ca., calcaneum; I, distal portion of the tarsus; i., ii., iii., iv., metatarsal bones.
