Mizuho OSI 5855-242 16-3/8" Padded Ilium Post for Orthopedic Trauma Tops

The Mizuho OSI 5855-242 is a professional-grade surgical subcomponent designed for high-stability pelvic and lower extremity positioning. As a cornerstone of the 5855 Orthopedic Trauma Top accessory suite, this 16-3/8 inch post serves as the primary lateral anchor for Total Hip Arthroplasty (THA) and pelvic fracture reductions. The included specialized padding is a critical safety feature; it protects the patient’s ilium from the high-torque forces generated during femoral broaching and acetabular reaming, providing a stable yet cushioned interface.

Constructed from high-tensile surgical alloys, the 5855-242 is built to withstand the extreme mechanical loads of the orthopedic OR. Its precision-milled base integrates seamlessly with Mizuho OSI modular rail systems, ensuring a "lock-steady" connection that eliminates intraoperative shifting during the most demanding reduction maneuvers.

Clinical & Operational Advantages

• Enhanced Patient Safety: The integrated pad reduces point-pressure on the iliac crest, mitigating the risk of postoperative skin necrosis or bruising in high-tension cases.

• Rigid Pelvic Containment: Maintains true perpendicular pelvic orientation, which is essential for the correct anatomical placement of acetabular components.

• High-Profile Reach: The 16.3" height is ideal for bariatric patients or setups involving thick table overlays, ensuring the post provides effective stabilization above the mattress line.

• C-Arm Optimized: The slim, vertical profile and radiolucent-friendly pad materials are designed to minimize artifacts during fluoroscopic "Inlet/Outlet" pelvic views.

Condition

• Status: Used – Functional System Subcomponent.

• Origin: Carefully extracted from a larger Mizuho OSI system to preserve mechanical integrity and mounting tolerances.

• Functional Assessment: The post is structurally sound with no stress fractures or bends. The mounting base is clean, and the included padding is intact and resilient.

• Cosmetic Status: Shows visible signs of professional usage, including surface scuffs and typical finish wear consistent with a trauma OR environment. These do not affect the mechanical safety or performance of the support.

• Reprocessing Note: This item is provided non-sterile. The post must be disinfected and the pad processed according to your facility’s Mizuho OSI equipment protocols prior to clinical use.
