OrthoMark® and x-ray magnification

Historically, orthopedic surgeons used precisely constructed plastic "overlays" matched up with anatomy in standard X-Ray films to calculate the magnification factor and, to a degree, determine the correct prosthetic to be used in surgery. The rapid introduction and implementation of digital x-ray rendered standard overlays useless.

It didn't take long for orthopedic templating software packages to become available for digital imaging, however, in order to effectively plan for surgery there was still a need to determine the magnification factor inherent in the image. Many different methods were used but all shared a degree of difficulty and often provided unacceptable results. What was needed was an x-ray marker with consistent dimensions from any angle that was capable of being positioned over a wide range of locations.

By positioning OrthoMark's solid, 1 inch (25.4mm) stainless steel calibration ball at the precise anatomical plane of the shoulder, hip, knee—or any anatomy for that matter—during x-ray imaging, surgical planning software is able automatically find the x-ray marker in the image, calculate the x-ray magnification factor, and determine the true size of the anatomy in question. This helps to ensure that the appropriate prosthetic is selected before surgery.

We created OrthoMark® in 2005 and it's been working as expected since. A simple, affordable, and very functional product. We believe it is the most functional and adaptable product on the market.

OrthoMark® is available with a variety of bases and attachment methods and comes with a 25" arm which can be easily extended at any time. All parts are US supplied and readily available. Our solid stainless-steel calibration ball doesn't degrade when surrounded by larger body mass. If there is a special application that is needed for your facility, give us a call and we'll create it.


*OrthoMark® works best with the following cleaning agents: Acetone, Alcohol (which happens to be an effective decontaminant for non-surgical products used with humans. Read more on that here), Ethyl, Detergents, Lacquer solvents, and Sodium Hydroxide.

OrthoMark® carries a 1-year warranty against manufacturing defects.

That being said, over the lifetime of OrthoMark® - over 19 years and thousands of sales - we have had only 7 (seven) product failures. Two were due to an abraded suction cup (manufacturing defect not caught), two were due to the lock button popping off, one was due to a drop which broke a plunger, one was due to a perfect drop that resulted in a disconnected arm, and the last was another perfect drop that disconnected the ball from the arm.

Since producing our very first unit we have attempted to provide the most sustainable product possible while keeping costs down.

Instead of designing custom boxes with printed imagery and tapes, we chose a simple corrugated cardboard box with minimal "stickering" in an effort to make our packaging more easily recyclable. Our internal packaging, while bubble wrap, is also easily recyclable.

Each unit is designed to last many years, and most of each is recyclable though the nature of each individual product has a different layer of difficulty In doing so.
