Mizuho OSI 5855-271 9-1/2" Pediatric Perineal Post Assembly

The Mizuho OSI 5855-271 is a professional-grade surgical subcomponent engineered specifically for pediatric and small-stature patient positioning. In orthopedic trauma and reconstructive surgery, the perineal post serves as the essential "counter-traction" point against which the traction boots pull to realign fractures. This Child Assembly features a reduced 9.5-inch profile, ensuring that the post provides secure pelvic blocking without interfering with the surgical site or the tight arc of a pediatric C-arm.

Constructed from high-tensile, surgical-grade materials, the 5855-271 is built to withstand the rigid mechanical forces of fracture reduction. Its precision-milled base is designed for rapid, "no-play" integration into the Mizuho OSI modular top, providing a stable foundation that is critical for achieving anatomical alignment in pediatric patients.

Key Specifications

• Manufacturer: Mizuho OSI

• Model Number: 5855-271

Clinical & Operational Advantages

• Targeted Pediatric Support: The shorter 9.5" height is anatomically calibrated for children, preventing the "over-height" interference common when using adult posts for small patients.

• Unobstructed Imaging Access: The slim, compact profile minimizes metal "bloom" in fluoroscopic images, giving the surgeon a clearer view of the growth plates and fracture lines.

• Modular System Stability: Engineered to the exact tolerances of the Mizuho OSI 5803/5855 series, ensuring a secure fit that eliminates intraoperative shifting.

• Rapid Procedural Setup: Lightweight and easy to handle, this assembly allows OR teams to transition from adult to pediatric configurations in seconds.

Condition

• Status: Used – Functional System Subcomponent.

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

• Functional Assessment: The post is straight, and the locking interface is clean and fully functional.

• Cosmetic Status: Shows visible signs of normal clinical usage, including surface scuffs and minor finish wear consistent with professional OR use. These do not impact the structural safety or performance of the post.
