Special Preview - Coming Soon

The Exact-Fit® De Mayo Lateral Positioner® represents a notable advancement over the original De Mayo Hip positioner in various aspects. This self-contained unit can accommodate all patients without requiring any component changes, regardless of their size. Unlike other positioners in the market, it uniquely connects both OR table rails into a rigid mechanical structure, providing unparalleled patient stability. Substantial enhancements in stability and the secure lateral positioning of patients have been achieved through changes in the clamping method and increased rigidity of its components.

The single-use protective pads employ a proprietary gel-infused slow recovery foam to guarantee the safe positioning of patients during procedures of any duration, instilling full confidence in the process. The Exact-Fit® De Mayo Lateral Positioner® conveniently stores fully assembled and can be promptly applied as soon as the patient is positioned on the operating room table.

San Francisco Orthopaedic Residency Program, St. Mary's Medical Center Total Hip Arthroplasty Hip Positioner Stability Study

  • Rotation of the pelvis during simulated motions of the pelvis varied widely based on hip positioner used.
  • As rotation of the pelvis alters the component positioning and may lead to implant malpositioning, motion should be limited.
  • In this study, the ExactFit hip positioner provided the most stability and thus may reduce the risk of component malpositioning and related complications.
  • This study was recently presented at the OREF Southwest Region Resident Research Symposium

  • “It’s very helpful in the OR, for example, we used it last weekend on a sub troch fracture in the lateral position and it helped us position.” 

    - Dr. James Cameron -MD
  • “I like the SteriBump because it’s lint-free, safer for patient positioning because it’s more secure and easier for the doctor to use than wrapping towels.”

    - Caitlyn Pourcho -RN, OR Circulator
  • “From establishing the position and securing the patient to performing procedures and testing range of motion, we created a system that’s faster and easier while also giving doctors completely unrestricted access to the surgical field.” 

    - Ed De Mayo M.D. -Device Inventor
  • Our hospital purchased SteriBump® to replace our handmade ‘bundles’ for many of the same reasons that hospitals moved away from re-sterilizing cloth OR table drapes some years ago. 

    - Anonymous -Central Sterile Services (CSS) Administrator
  • "The best reason I have for using the SteriBump is that it is sterile every time. The sterility is validated. We were using rolled blankets that were sterilized before this that were sterilized in Sterile Processing. It's one less item they have to deal with and try to keep up with."

    - Brenda Conbeer -OR Inventory Coordinator
