HEMIPELVECTOMY is the term most frequently applied to the operative procedure in which the entire lower extremity with the adjacent innominate bone is removed through the sacroiliac and pubic joints. Other descriptive, though more cumbersome, designations for this operation are interinnomino-abdominal amputation,1 interpelvi-abdominal disarticulation,2 sacroiliac disarticulation3 and disarticulation of the innominate bone.4
Hemipelvectomy offers the best method for eradication of primary, radioresistant malignant tumors of the ilium, ischium and pubis. It is also indicated for malignant tumors of the upper part of the thigh which encroach on or involve the innominate bone or pelvic parietes. A compromise with good surgical treatment of tumors has been made frequently in dealing with malignant growths of the upper part of the thigh by performing a disarticulation of the hip joint, a procedure in which it is often impossible to remove the tumor widely.
