hemicorporectomy

Hemicorporectomy is a radical surgery in which the body below the waist is amputated, transecting the lumbar spine. This removes the legs, the genitalia (internal and external), urinary system, pelvic bones, anus, and rectum. It is a major procedure recommended only as a last resort for people with severe and potentially fatal illnesses such as osteomyelitis, tumors, severe traumas and intractable decubiti in, or around, the pelvis. By 2019, 66 cases had been reported in medical literature.

==Medical uses== The operation is performed to treat spreading cancers of the spinal cord and pelvic bones. Other reasons may include trauma affecting the pelvic girdle ("open-book fracture"), uncontrollable abscess or ulcers of the pelvic region (causing sepsis) or other locally uncontainable conditions. It is used in cases wherein even pelvic exenteration would not remove sufficient tissue.
