Mizuho OSI 5855-137 16-3/4" Lateral Perineal & Counter-Traction Post

The Mizuho OSI 5855-137 is a professional-grade surgical subcomponent engineered for high-tension orthopedic trauma cases. As a vital part of the 5855 Orthopedic Trauma Top accessory suite, this 16-3/4 inch post serves as a rigid lateral stabilizer, preventing patient "roll" or "drift" during femoral nailing, acetabular reconstruction, and hip arthroscopy. Its extended height is specifically designed to clear thick pressure-relief padding and high-profile gel overlays, ensuring the post makes firm contact with the patient's anatomy to maintain stable pelvic alignment.

Constructed from high-tensile surgical alloys, the 5855-137 is built to withstand the significant mechanical loads inherent in fracture reduction. Its precision-milled base integrates seamlessly with the Mizuho OSI modular rail system, providing a "lock-steady" connection that eliminates intraoperative shifting during high-torque reaming or component impaction.
