pelvic resection classification
Systematic categorization of pelvic tumor resections based on anatomical zones (I, II, III) defined by the ilium, acetabulum, and ischiopubic rami.
Full Definition
The pelvic resection classification system, developed by Enneking and Dunham, divides the pelvis into three zones for surgical planning in pelvic sarcomas. Zone I encompasses the ilium above the acetabulum, Zone II includes the acetabulum and periacetabular region, and Zone III involves the ischiopubic rami below the acetabulum. Resections may involve single zones or combinations (I+II, II+III, I+II+III), with each pattern having distinct reconstructive requirements and functional implications.
Usage
Usage note: Always specify the exact zones involved rather than using generic terms like 'pelvic resection'.
