COMBAT-TIP: Combat-Optimized Method for Bone Alignment and Tourniquet Innovation in Pelvic Fractures, A Comparative...

Area of Science:

• Trauma care
• Orthopedic surgery
• Emergency medicine

Background:

• Pelvic fractures from high-energy trauma present significant prehospital challenges, often involving life-threatening hemorrhage.
• Commercial pelvic binders like the SAM Pelvic Sling II are standard but may be limited in austere environments.
• Alternative stabilization methods are needed for resource-limited prehospital settings.

Purpose of the Study:

• To evaluate an innovative technique using two Combat Application Tourniquets II (CAT II) connected in tandem for pelvic fracture stabilization.
• To compare the intrapelvic pressure generated by the CAT II method against the traditional SAM Pelvic Sling II.

Main Methods:

• A human cadaveric model with surgically created open-book pelvic fractures was utilized.
• Intrapelvic pressure was measured using a Foley catheter.
• The SAM Pelvic Sling II and the tandem CAT II configuration were applied three times each, with pressure recorded.

Main Results:

• The tandem CAT II technique generated a statistically significant, albeit small, increase in intrapelvic pressure compared to the SAM Pelvic Sling II.
• Both methods demonstrated the ability to apply pressure to the pelvis.

Conclusions:

• The described method of using two tandem CAT II devices appears to be a potentially feasible and effective alternative for pelvic fracture stabilization.
• Further research is necessary to validate this technique for clinical application in real-world patient scenarios.
