Precision® MIS
Not all bunion surgery needs to violate your joint by fusion. The Precision® MIS Bunion System allows your surgeon to make 3D correction without fusing your joint.
The Precision® MIS Bunion System, may be considered for mild to moderate bunion deformity.
This means that the bunion isn’t severe enough to require a more extensive procedure like a Lapidus. The Precision® MIS Bunion System procedure involves cutting and repositioning the metatarsal bone to correct the angle between the metatarsal and the phalanx bones (bones of the toe). It is used to realign your big toe to reduce the prominence of your bunion. This procedure does not involve the fusion of joint bones so it can preserve some degree of joint mobility.
This procedure is generally associated with a shorter recovery period compared to the Lapidus procedure.

Frequently Asked Questions
How does the Precision® MIS Bunion System differ from traditional open procedures?
The objective of all bunion surgeries remains consistent: to realign the foot, relieve pain, and restore functionality. Traditional “open” procedures involve using substantial incisions on the foot to access the treatment area. While these larger incisions provide the surgeon with better visibility of the bone structures, they can result in greater scarring and potential damage to nearby soft tissues. The Precision® MIS Bunion System allows the same corrective procedure through smaller, minimally invasive incisions, and ensures controlled correction and precise targeting.
How is the Precision® MIS Bunion System different from other procedures that claim to be “minimally invasive”?
The Precision® MIS Bunion System employs a completely percutaneous technique, where the surgery is conducted through small punctures in the skin rather than the larger incisions typical in traditional open procedures. Fewer and smaller soft tissue incisions also can contribute to a lowered risk of infection and postoperative stiffness.
Is the Precision® MIS Bunion System procedure considered “3D” correction?
The term 3D is used to describe bunion procedures that not only shift bone but rotate it as well. These three planes are considered “3D” correction. The Precision® MIS Bunion System offers 3D correction.
Can anyone with a bunion get the Precision® MIS Bunion System procedure?
Most mild to moderate bunion deformities can be surgically corrected with the Precision® MIS Bunion System. Ultimately, your physician will determine whether you are an appropriate candidate for the procedure. Click here to find a foot and ankle surgeon near you who uses the Precision® MIS Bunion System.
Can any doctor perform the Precision® MIS Bunion System procedure?
Many surgeons are being trained every week on this procedure. Doctors found on the Find a doctor feature have received in-person training specifically on the Precision® MIS Bunion System and have been performing the procedure.
Is it possible for me to undergo a minimally invasive bunion procedure if I have had previous bunion surgery?
Revision bunion surgery can be done with the Precision® MIS Bunion System but you will need to have this conversation with a surgeon specializing in this technique. You can Find a doctor here.
Can I have my hammertoe and/or bunionette deformities fixed at the same time? Are minimally invasive techniques available for those procedures also?
Numerous individuals with bunions may also present with other, frequently interlinked, foot abnormalities that can be dealt with during a single surgery. Depending on your surgeon’s technique, these procedures may allow a minimally invasive approach as well. It is advisable to seek the advice of your surgeon regarding this matter.
Can I have both feet operated on at the same time?
While it is technically safe to undergo surgery on both sides simultaneously, it is typically advised to have one foot operated on separately for a smoother recovery experience.
Is this procedure covered by insurance?
Yes, most insurance policies cover bunion correction procedures. Ask your doctor and insurance provider for specific details.
Do I qualify for the Precision® MIS Bunion System Procedure if I have comorbidities like diabetes?
Please consult with your surgeon regarding your specific treatment plan as it relates to your health.
