Kalamazoo, Michigan-based Stryker designed the system to treat bunions using a minimally invasive surgical reduction. It uses the hallux valgus deformity and subsequent fusion of the first metatarsal cuneiform joint.
Traditionally, surgeons performing Lapidus bunion procedures use an open approach. Stryker cites surgeon and patient advantages with minimally invasive techniques, though. PROstep MIS Lapidus offers powerful fixation stability through a minimal incision.
The new technology features MIS joint preparation, triplanar reduction and a three-screw construct that creates a tension band for biomechanical stability.
Stryker highlights benefits including a 2.5% decrease in recurrence compared to open Lapidus procedures. The company saw a 9% reduction in non-union rates as a result of MIS Lapidus joint preparation, too. It also saw a 76% reduction in scar size compared to open bunion correction. Stryker reported less opioid usage post-operation compared to open Lapidus procedures.
Dr. Alastair Younger, head of distal extremities at the University of British Columbia, said the procedure offers “a better option” for patients worried about cosmetic scarring. Younger said it can mitigate the potential loss of correction caused by improper bone healing, too.
“PROstep MIS Lapidus puts the power back in our surgeon customers’ hands to make the best decision for their patients,” said Patrick Fisher, VP and GM for Stryker’s Foot and Ankle business unit. “At Stryker, we’re continuing to expand our surgery options to support our commitment to advancing minimally invasive foot and ankle surgery.”
