The SAM Pelvic Sling II is the first and only force-controlled circumferential pelvic belt scientifically proven to safely reduce and stabilize open-book pelvic ring fractures. The patented AUTOSTOP buckle engages with an audible click when optimal circumferential pressure (150N / 33 lbs) is reached, preventing dangerous over-tightening. Available in Small (27–45 in.), Standard (32–50 in.), and Large (36–54 in.); NSN 6515-01-509-6866. MRI safe.

Product Overview
Pelvic fractures — particularly open-book injuries of the pelvic ring — are associated with life-threatening hemorrhage from disruption of the pelvic venous plexus and iliac vessels. A displaced pelvic ring can accommodate 3–4 liters of blood in the retroperitoneal space, leading to rapid exsanguination. Circumferential compression to reduce and stabilize the pelvis is the standard prehospital intervention to limit ongoing hemorrhage, making it a core component of TCCC-influenced trauma protocols.
The SAM Pelvic Sling II is the clinical standard for prehospital pelvic stabilization. Its critical differentiator is the patented AUTOSTOP buckle system: as the sling is tightened, two metal prongs emerge and click to confirm when 150N (33.7 lbs) of circumferential force has been achieved — the clinically validated optimal force for pelvic ring reduction. No other commercial pelvic binder provides active force-limitation; improvised or sheet-based alternatives allow unlimited force application, which can cause over-compression injuries, pressure ulcers, and interference with vascular and urogenital structures.
Application is rapid and requires no specialized equipment. The three-step process — position, pull, and click — is typically completed in under one minute and can be performed by any first responder with minimal training. The posterior slider allows the device to be repositioned for patient transfers and log-rolls without removing the sling. The sling is radiolucent (X-ray and CT compatible) and MRI safe when applied before entering the MRI environment, supporting continuity of immobilization through the full diagnostic and treatment pathway.
Clinical Evidence
The SAM Pelvic Sling is supported by multiple peer-reviewed studies demonstrating its efficacy in reducing open-book pelvic fractures. Biomechanical studies confirm that the 150N AUTOSTOP force threshold provides anatomically adequate pelvic reduction without the complications associated with over-tightening. The standard size (32–50 inch hip circumference) fits approximately 95% of the adult population, making it suitable as a single-SKU solution for most trauma kits and caches.
