Lapiplasty®

3D Bunion Correction®

The Lapiplasty® System is relentlessly innovated to drive efficiency. Streamlined instrumentation helps visualize and dial in precise 3D corrections and ensures the correction is maintained throughout the procedure.

Rapid return to weight bearing

Patients return to protected weight bearing at an average of 7.7 days10, compared to an average 6-10 weeks with other Lapidus fusion procedures 11

Key Surgical Steps

Step 1: Correct

Make Your Correction Before You Cut

The Lapiplasty® Positioner is engineered to quickly and reproducibly correct the alignment in all three planes, establishing and holding true anatomic alignment of the metatarsal and sesamoids.1

Step 2: Cut

Perform Precision Cuts with Confidence

The Lapiplasty® Cut Guide delivers precise cuts with the metatarsal held in the corrected positions, ensuring optimal cut trajectory with only 2.4-3.1mm average metatarsal shortening.3

Step 3: Compress

Achieve Controlled Compression of Joint Surfaces

The Lapiplasty® Compressor is designed to deliver controlled compression4 to the precision-cut joint surfaces, while maintaining 3-plane correction.

Step 4: Fixate

Apply Multiplanar Fixation for Robust Stability

Low-profile Biplanar Plating provides biomechanically-tested5,6 multiplanar stability for rapid return to weight-bearing in a boot.1
