Since SPD results after high energy injuries, like a fall from height, traffic accidents or blast injuries , most of the times it is found in a polytraumatized patient, associated with other life-threatening injuries Conservative treatment is chosen only in patients who are not fit for surgery or have concomitant injuries that will require a period of immobilization longer than three months and in those presenting mild displacement at the fracture sites]. Otherwise, SPD lesions are best treated by surgical procedures.
