Different classificationsystems exist, some are based on the mechanism of injury, some on anatomic patterns and some are focusingon the resulting instability requiring operative fixation. The optimal treatment strategy, however, should keepinto consideration the hemodynamic status, the anatomic impairment of pelvic ring function and the associatedinjuries. The management of pelvic trauma patients aims definitively to restore the homeostasis and the normalphysiopathology associated to the mechanical stability of the pelvic ring. Thus the management of pelvic trauma must be multidisciplinary and should be ultimately based on the physiology of the patient and the anatomy of the injury. This paper presents the World Society of Emergency Surgery (WSES) classification of pelvic trauma and the management Guidelines.Keywords: Pelvic, Trauma, Management, Guidelines, Mechanic, Injury, Angiography, REBOA, ABO, Preperitoneal pelvic packing, External fixation, Internal fixation, X-ray, Pelvic ring fracturesBackgroundPelvic trauma (PT) is one of the most complex manage- ment in trauma care and occurs in 3% of skeletal injur- ies [1–4]. Patients with pelvic fractures are usually young and they have a high overall injury severity score (ISS) (25 to 48 ISS) [3]. Mortality rates remain high, particularly in patients with hemodynamic instability, due to the rapid exsanguination, the difficulty to achieve hemostasis and the associated injuries [1, 2, 4, 5]. For these reasons, a multidisciplinary approach is crucial to manage the resuscitation, to control the bleeding and to manage bones injuries particularly in the first hours from trauma. PT patients should have an integrated manage- ment between trauma surgeons, orthopedic surgeons, interventional radiologists, anesthesiologists, ICU doctors and urologists 24/7 [6, 7].* Correspondence: federico.coccolini@gmail.com1General, Emergency and Trauma Surgery, Papa Giovanni XXIII Hospital, P.zza OMS 1, 24128 Bergamo, ItalyFull list of author information is available at the end of the articleAt present no comprehensive guidelines have been published about these issues.
