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).
CondutaNonoperative management: stable ring injuries are treated conservatively with protected weight-bearing and analgesia; surgery is generally not required.
RiscoLowest-risk pattern: stable pelvic ring injuries carry lower mortality than unstable ones (stable ~7.9% vs unstable ~11.5% in reported series).

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).
CondutaOften 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.
RiscoIntermediate-risk pattern: rotational instability with potential for significant hemorrhage; open-book (AP-compression) injuries can enlarge pelvic volume and bleed.

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).
CondutaOperative 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).
RiscoHighest-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.
