## Categorias

| Código | Rótulo | Critérios | Conduta | Risco | Localizador | Verificado |
| --- | --- | --- | --- | --- | --- | --- |
| A | Type A, stable | Stable pelvic ring injury with the posterior sacroiliac complex intact; the ring is both rotationally and vertically stable (e.g. avulsions or minimally displaced ring fractures). | Nonoperative management: stable ring injuries are treated conservatively with protected weight-bearing and analgesia; surgery is generally not required. | Lowest-risk pattern: stable pelvic ring injuries carry lower mortality than unstable ones (stable ~7.9% vs unstable ~11.5% in reported series). | StatPearls 'Pelvic Ring Injuries' NBK544330, Treatment/Management section (Type A = nonoperative) and reported stable vs unstable mortality (~7.9% vs ~11.5%). | ✓ |
| B | Type B, rotationally unstable | Partial disruption of the posterior sacroiliac complex producing a rotationally unstable but vertically stable pelvis (includes open-book/AP and lateral-compression patterns). | Often operative depending on displacement: a pelvic binder/external fixation controls open-book diastasis acutely, and ORIF (e.g. anterior plating/symphyseal fixation) is used for significant rotational instability; minimally displaced patterns may be managed nonoperatively. | Intermediate-risk pattern: rotational instability with potential for significant hemorrhage; open-book (AP-compression) injuries can enlarge pelvic volume and bleed. | StatPearls 'Pelvic Ring Injuries' NBK544330, Treatment/Management (Type B - binder/external fixation/ORIF by displacement) and hemorrhage discussion. | ✓ |
| C | Type C, rotationally and vertically unstable | Complete disruption of the posterior sacroiliac complex producing a pelvis that is both rotationally and vertically unstable (may be unilateral, bilateral, or associated with an acetabular fracture). | Operative management is indicated: resuscitation with a pelvic binder, angiographic embolization or preperitoneal packing for hemodynamic instability, then definitive posterior and anterior fixation (percutaneous SI screws, external fixation, ORIF). | Highest-risk pattern: greatest hemorrhage and mortality among pelvic ring injuries; open unstable fractures approach ~50% mortality, and the pelvic venous plexus is the bleeding source in about 80% of cases. | StatPearls 'Pelvic Ring Injuries' NBK544330, Treatment/Management (Type C operative, embolization/packing) and risk data (open-fracture mortality ~50%, venous plexus source ~80%, unstable mortality ~11.5%). | ✓ |
