In 1939, a fifteen-year-old boy was brought to this Hospital with a large sarcomatous tumor arising from the lesser trochanter and filling all the space between the trochanter and the tuberosity of the ischium. Disarticulation of the extremity at the hip joint was obviously imposible, and the tumor, not being radio-sensitive, grew to tremendous proportions. Finally, a pathological fracture developed, and his last few months were painful and miserable beyond description.

This experience convinced the authors that in such a case some effort should be made to eradicate the tumor, however drastic the operative procedure, or how little the chance for success. In-order to do this, a radical removal of the lower extremity above the hip joint would be necessary (Fig. 1).

Since the operation is carried out between the peritoneum and the innominate bone it is referred to a interinnomino-abdominal, or interilio-abdominal amputation. Hindquarter resection, transpelvic amputation, hemipelvectomy, and transiliac amputation are some of the. various names applied to the operative procedure.

Showing the regions at which the innominate bone, is detached from the pelvis. This operation been called interinnomino-abdominal amputation, interilio-abdominal amputation, transpubic amputation, transiliac amputation, transacral amputation, transacro-illiac amputation, hemipelvectomy, hindquarter amputation, transpelvic amputation, hemipelvic amputation.

The first recorded operation of this kind was performed in 1889.
