Young-Burgess classification
# Young-Burgess classification

The Young-Burgess classification is a system of categorizing pelvic fractures based on fracture pattern, allowing judgment on the stability of the pelvic ring.

## Classification

| Type | Anterior Posterior Compression | Lateral Compression | Vertical Shear |
| - | - | - | - |
| I | APC I - Symphysis widening < 2.5 cm | LC I - Compression fractures of the pubic rami (superior pubic ramus and inferior pubic ramus) and ipsilateral anterior sacral ala | VS - Posterior and superior directed force |
| II | APC II - Symphysis widening > 2.5 cm. Anterior SI joint diastasis. Disruption of sacrospinous and sacrotuberous ligaments | LC II - Rami fracture and ipsilateral posterior ilium fracture dislocation | VS - Posterior and superior directed force |
| III | APC III - SI dislocation with associated vascular injury | LC III - Ipsilateral lateral compression and contralateral APC | VS - Posterior and superior directed force |
