What is Stryker® Minimally Invasive Surgery for Bunions?

Stryker® minimally invasive surgery (MIS) for bunions is an advanced, less invasive approach to correct hallux valgus (commonly known as a bunion) with improved recovery and cosmetic outcomes. This technique uses Stryker®’s PROstep® MIS Platform, which is specifically designed to correct hallux valgus (bunion deformities) using tiny incisions, minimal soft tissue disruption, and precision instrumentation.

PROstep® is a proprietary system by Stryker® that includes:

• Miniature surgical instruments and burrs
• A fluoroscopy-guided technique
• Specialized fixation implants (such as low-profile screws)

What are the Indications for Stryker® Minimally Invasive Surgery for Bunions?

Stryker®’s PROstep® minimally invasive surgery is typically indicated for the treatment of bunions. A bunion is a bony prominence (bump) at the base of the big toe, which often results in pain, redness, and rubbing of the toe against the footwear. With this condition, the 1st metatarsal bone of the big toe abnormally angles outward towards the other foot from its joint in the midfoot.

Ideal candidates for Stryker®’s PROstep® minimally invasive surgery include:

• Patients with mild-to-moderate bunions who want faster recovery and minimal scarring
• Individuals who want to avoid extensive soft-tissue dissection or prolonged immobilization
• Those preferring less postoperative pain and reduced opioid use

What Does the Procedure for Stryker® Minimally Invasive Surgery for Bunions Involve?

In general, Stryker®’s PROstep® minimally invasive surgery will involve the following:

• The procedure is typically performed under local anesthesia with sedation or regional block, often on an outpatient basis.
• Several incisions (typically <5 mm each) are made along the side of the big toe and foot - much smaller than traditional open surgery.
• A high-speed burr (part of the PROstep® toolset) is inserted through the incision. The surgeon makes a precise cut in the metatarsal bone to realign the toe joint.
• Using fluoroscopy (live X-ray), the surgeon views the bones in real time to ensure accurate repositioning of the metatarsal head.
• Once aligned, the surgeon inserts PROstep®-specific screws through the small incision to hold the bone in its corrected position. These screws are designed to be low-profile and often stay in the foot permanently.
• In some cases, surrounding tendons or ligaments may be gently released or tightened to optimize toe alignment.
• The small incisions are closed with a stitch or surgical tape, and a sterile dressing is applied.

What to Expect After Stryker® Minimally Invasive Surgery for Bunions?

After Stryker® PROstep® minimally invasive surgery for bunions, patients can typically expect a faster and more comfortable recovery compared to traditional open surgery. Most individuals are able to bear weight on the foot the same day using a special post-operative boot. Swelling and mild discomfort are common for the first few days, but pain is usually well-controlled with minimal medication. The small incisions heal quickly, reducing the risk of scarring and infection. Patients often return to regular shoes within 4 to 6 weeks, with full activity resuming by 8 to 12 weeks, depending on healing progress. Follow-up visits are scheduled to monitor bone alignment and ensure proper recovery.

What are the Benefits of Stryker® Minimally Invasive Surgery for Bunions?

Benefits of Stryker®’s PROstep® minimally invasive surgery for bunions over traditional open surgery include:

• Smaller scars
• Less pain
• Minimal soft tissue disruption
• Faster recovery
• Improved cosmetic outcome
• Lower recurrence and improved bone healing
• Higher patient satisfaction

What are the Risks and Complications of Stryker® Minimally Invasive Surgery for Bunions?

Risks and complications of Stryker® PROstep® minimally invasive surgery for bunions are generally low but can include:

• Infection at the incision site
• Nerve irritation or numbness
• Delayed bone healing (nonunion or malunion)
• Recurrence of the bunion
• Hardware irritation or need for screw removal
• Overcorrection or undercorrection of the deformity
• Stiffness or limited joint mobility
