Stryker Corporation debuted its PROstep MICA SOLO Guide at the recent American College of Foot and Ankle Surgery with the objective of significantly shortening the learning curve, streamlining, increasing reproducibility, and reducing the need for a surgical assistant in minimally invasive bunion surgical procedures.
Stryker Introduces MIS Bunion Surgery All-in-One Guide
According to the company, the new guide “acts as a third hand.” It provides “automatic targeting of the screw, stabilization of the head fragment and a controlled, adjustable shift.”
According to Stryker, the product’s key benefits include:
- Faster return to function
- Less pain
- Smaller scars
- Overall increased patient satisfaction
- Less need for opioids post-op
“I am delighted that we now have a precision tool for this technique right where the surgeon needs it,” said David Redfern, FRCS, foot and ankle surgeon at Cleveland Clinic London Hospital. “The PROstep MICA SOLO Guide is like having an expert assistant at hand to make the necessary surgical steps in this procedure much easier.”
The VP of Marketing & Medical Education, Foot & Ankle at Stryker, Michael Rankin, explained to OTW, “The PROstep MICA SOLO Guide greatly simplifies the way MIS [minimally invasive surgery] bunion procedures are performed. The all-in-one guide eases the learning curve and streamlines the procedure, allowing for reproducibility and a decreased need for a surgical assistant.”
“Traditional minimally invasive bunion procedures have a high learning curve. The shifting of the bone, the tilting into varus, and the frontal plane rotation can be challenging, especially when trying to perfect driving in a k-wire in multiple planes. At the American College of Foot and Ankle Surgery, surgeons expressed that the MICA guide may make these procedures overall much less stressful, as it has the potential to free up a set of hands.”

Discussion
This is a fascinating development. In my practice we've seen similar outcomes with the revised protocol. The key differentiator seems to be patient selection criteria. Has anyone else noticed the correlation with BMI thresholds?
Great point. I'd push back slightly on the conclusion, the sample size in the cited study is too small to draw population-level inferences. That said, the directional signal is compelling and worth a larger RCT.
We implemented a similar approach last year. Early results are promising but we're still gathering 12-month follow-up data. Happy to share our protocol if anyone is interested.
