The Technique

How does 3D MIS Bunionectomy™ work?

Harvard trained surgeon Dr. Homam Badri developed this innovative technique using minimally invasive surgery. 3D MIS Bunionectomy™ causes far less damage to your foot, prevents recurrence of the bunion deformity, and gives you the results you deserve with reduced pain and faster recovery.
The 3D MIS Bunionectomy™ system takes advantage of proven medical technology used in more than 50,000 procedures worldwide through ProStep by Wright Medical, leaders in minimally invasive foot and ankle surgery.

After surgery with PROstep™

3D MIS Bunionectomy™ surgery can both reduce pain and improve the appearance of your feet. However, for best results, see your doctor as scheduled and follow all recovery instructions carefully. As opposed to open surgery, your feet may feel much better sooner and you may feel you are ready to get back to your life. PLEASE FOLLOW YOUR SURGEON’S INSTRUCTIONS.

What is 3D MIS Bunionectomy?

The 3D MIS Bunionectomy™ Minimally Invasive System (MIS) Bunionette is the first implant which combines the strength of an intramedullary rod with the security of a locking plate for use in Tailor’s Bunion deformity correction. Tailor’s Bunion (also called Bunionette) is a notoriously difficult deformity to correct due to the small size of the distal fifth metatarsal, which often limits both the stability of shifting osteotomies as well as the ability to place hardware in mechanically stable locations. For example, a common practice is to place a K-wire parallel to the fifth ray that is only driven

into the proximal fragment, with the goal of merely buttressing the distal fragment from shifting back to its previous position. This leaves the distal fragment unfixed and potentially able to shift dorsally or plantarly, or even rotate axially. The PROstep MIS Bunionette system gives the surgeon a means to more fully fixate the distal fragment while avoiding relying on a K-wire sticking out of the end of the toe, and is still performed in a minimally invasive procedure.

About The Implant

The Implant in the 3D MIS BUNIONECTOMY ™ system is designed to provide a much more robust fixation of the distal fragment while also providing a more secure fixation into the proximal fragment when compared to a buttressing K-wire technique. It achieves this using a larger proximal intramedullary rod than typically seen with K-wires. This makes the Implant more suitable to remaining stable in the patient.
Also, instead of merely buttressing the distal fragment, the Implant is furnished with a distal locking hole to accept an OrtholocTM 2.4mm locking screw (12mm length variant is included in the Implant Sets). This helps prevent dorsal subluxation of the distal fragment when compared to the buttressing K-wire technique. In order to achieve good proximal fixation, Broaches are included with the system to create a supportive shell of bone, rather than removing that bone with a drill. The Implants also have 15° of varus built-in to correct the valgus of the fifth metatarsal (metatarsus quintus valgus) at the level of the metatarsal head.
