Minimally invasive

bunion correction surgery

What is PROstep MIS?

PROstep minimally invasive surgery involves performing surgery through tiny incisions, usually under some form of image guidance. The incisions are just a few millimeters long compared to 3-5 inch incisions used in traditional open bunion surgery.1,2

This type of surgery has been enabled by advances in technology which have allowed the development of very small drills (called burrs). These can be used to make delicate cuts in the bones of the foot to re-align them through very small incisions. The surgery is carried out under image guidance in surgery and allows your surgeon to have eyes inside the foot when performing surgery.

Benefits of PROstep minimally invasive surgery

When compared to traditional open bunion surgery, PROstep results in:

  • Quicker return to function2,3

  • Less pain1

  • Smaller scars1,2

  • Overall increased patient satisfaction1

  • Less need for opioids post-op4

Get back on your feet faster

Bunions can really slow you down but having a traditional open surgery can require a longer, more painful recovery, which means putting life on pause. If you desire a quicker return to function2,3 such as driving, working, exercising or other activities with doctor approval, choose PROstep MICA minimally invasive surgery—and get relief.

A visible difference

Addressing bunion pain and preserving the natural joint are both key goals of the PROstep approach — a difference you can see as much as you can feel.

Faster recovery

Patients who experienced minimally invasive surgery on average can recover faster compared to a traditional open procedure.2,3

How does it work?

PROstep MIS uses minimally invasive techniques and specialized equipment to ensure minimal disruption to the foot. Smaller micro-incisions are made at targeted positions in the foot as opposed to the larger incisions made in traditional open procedures. Then an X-ray is used to guide a small, specialized burr, which shaves the bone at the joint and inserts stabilizing screws to re-align the toe, allowing for less scarring than a traditional procedure.

Important information

Bunion surgery is intended for individuals with deformities of the first metatarsophalangeal joint (the joint at the base of the big toe). Based on a determination jointly made by a patient and a healthcare professional in consideration of a patient’s unique clinical factors, bunion surgery may be appropriate for certain individuals, and certain products, like those discussed below, may be used for treatment.

The PROstep MICA Screw System is intended to be used for fixation of bone fractures (e.g., repair of broken bones) or bone reconstruction (e.g. restoring shape, alignment or structure of a damaged, deformed or surgically altered bone).

The Ortholoc 2 Lapidus with Rotation System is intended to be used for the stabilization and fixation of fresh fractures, revision procedures, joint fusion (joining together), and reconstruction of bones of the feet and toes. Specific examples include: Arthrodesis (surgical fusion) of the first metatarsal cuneiform joint (base joint of the big toe).

The ProStep MICA Screw System and the Ortholoc 2 Lapidus with Rotation System are intended for patients in generally good health. The area treated should have good blood flow and normal nerve function. The skin must be healthy enough to fully cover the implant. The muscles and tendons should be strong enough to support normal movement. The bone also needs to be strong enough to hold the implant securely.

The Ortholoc 2 Lapidus with Rotation System and the PROstep MICA Screw System are not appropriate for patients who have certain types of infections, physiologically or psychologically inadequate patients (patients who have certain mental health conditions or physical conditions that may make them inappropriate candidates for surgery), patients with irreparable tendon system (tendons are so damaged they cannot be repaired), growing patients with open epiphyses (patients who’s bones are still growing), patients with high levels of activity, or patients that may benefit from more conservative treatment (such as footwear modification or physical therapy).

Any surgery has serious risks. The risks associated with the aforementioned product systems and/or procedures include but are not limited to infection, pain, swelling, and inflammation around the implant. Certain implant-related risks which may lead to revision of the implant or additional surgeries include implant fracture (breakage), loosening, dislocation (moving out of place). Additional risks include bone resorption (bone loss) or bone over-production (extra bone growth), allergic reaction to the implant materials, untoward histological responses possibly involving macrophages and/or fibroblasts (the body, including the body’s cells and tissues, may react abnormally to the implant over time), migration of particle wear debris possibly resulting in a bodily response (small pieces of the implant may wear off and migrate through the body resulting in a reaction), and embolism (blocked blood vessel). Additionally, delayed union (bone is taking longer than expected to heal), non-union (failure of bone to heal) or failure of the implant could occur.

Only your doctor can make the medical decision about which products and treatments are right for your own individual condition. As with any surgery, bunion surgery carries certain risks. Your surgeon will explain all the possible complications of the surgery, as well as side effects. Additionally, the lifetime of an implant is not infinite and varies with each individual. Also, each patient will experience a different post-operative activity level, depending on their own individual clinical factors. Your doctor will help counsel you about how to best maintain your activities to potentially prolong the lifetime of the device. It is important to closely follow your doctor's instructions regarding post-surgery activity, treatment and follow-up care.
