FOR STABILIZATION OF PELVIC FRACTURES WITH THE CORRECT FORCE. The SAM Pelvic Sling II was designed not to over-tighten or under-tighten, unlike other commercial binders which allow unlimited force to be applied to the patient. , Researchers at Legacy Health System utilized cadaver studies and clinical trials to determine the optimum range of force required to safely and effectively close an unstable pelvic fracture. The SAM Pelvic Sling II's patented Autostop buckle is programmed to stop your pull once the correct compression force has been obtained. This is vital in high stress environments where over-tightening by emergency medical personnel under duress could potentially be extreme and harmful. Trauma surgeons around the world recognize the importance of stabilizing pelvic fractures during the critical first golden hour following severe trauma. Because of the potentially devastating haemorrhage associated with such fractures, standard first aid protocol includes applying some type of circumferential binder around the victim's hips.
