What is PROstep™?

PROstep™ is a minimally invasive surgical technique developed by Wright Medical, the leader in foot surgery. Over 50,000 procedures have been performed worldwide with Wright technology.1 Mr. David Redfern and Dr. Joel Vernois first described this operation in a UK French collaboration and have trained surgeons worldwide in their techniques.

The standard “open” approach to these procedures includes opening of the skin, soft tissue, and/or joint capsule and then the utilization of a micro sagittal saw to make osteotomies into the bones of the foot. The foot is then aligned back to anatomical norms and fixated with screws or plates designed for open procedures. PROstep™ procedures are performed with a percutaneous 3-5mm incision (versus 3-5 inches for open procedures), and the osteotomies are made with a rotating burr instead of a micro sagittal saw.

Our surgeons have found that the potential advantages of using a burr for minimally invasive procedures include:

  • less pain3
  • earlier return to function compared to an open procedure3,4
  • smaller incision2
  • less soft tissue disruption2
  • smaller scars2

PROstep™ procedures are carried out with assistance from x-ray to allow for visualization of the boney structures.

At the heart of these PROstep™ procedures is a burr, PROstep™ Power Box to drive the burr, specialized instruments designed for percutaneous procedures, and the training that goes along with the procedure. We offer the following procedures under the banner of PROstep™

  1. Chevron Osteotomy
  2. Akin Osteotomy
  3. Cheilectomy
  4. Distal Metaphyseal Metatarsal Osteotomy (DMMO)
  5. Calcaneal Osteotomy
