Why perform the Lapiplasty® Procedure?
Because metatarsal frontal-plane rotation mattersWhile hallux valgus has traditionally been viewed as a transverse plane deformity, research indicates that it is actually a three-plane deformity with 87% of patients having abnormal frontal-plane rotation (i.e. pronation) of the 1st metatarsal.3 Correction of metatarsal rotation is critical for restoration of anatomic first ray alignment (MTP joint congruity and sesamoid position), which left unaddressed, is associated with up to 12x likelihood of radiographic recurrence.4,5,6 Due to the ability to address the triplanar deformity at its origin, the 1st tarsometarsal (TMT) joint provides the optimal surgical site for true anatomic restoration.

What is the Lapiplasty® Procedure?
An instrumented, reproducible approach to 3-plane correction with rapid return to weight-bearing
Make your correction before you cutThe 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.
Perform precision cuts with confidenceThe Lapiplasty® Cut Guide delivers precise cuts with the metatarsal held in the corrected position, ensuring optimal cut trajectory while virtually eliminating the risk of metatarsal shortening.
Achieve controlled compression of joint surfacesThe Lapiplasty® Compressor delivers over 150N of controlled compression7 to the precision-cut joint surfaces, while maintaining the 3-plane correction.

How does the Lapiplasty® Procedure work?
Key Surgical Steps*
1. Joint ReleaseRun sagittal saw cengruously down the 1st TMT joint to mobilize and plane the joint surfaces.
2. Anatomic CorrectionApply the Lapiplasty® Positioner, simultaneously securing the IM angle, frontal-plane rotation, and sagittal alignment in corrected position.
3. Precision CutsSecure the Lapiplasty® Cut Guide and make precise joint cuts with the triplanar correction held In place.
4. Joint DistractionApply the Lapiplasty® Compressor over the Cut Guide Pins to distract the joint for removal of bone slices and fenestration of the joint surfaces.
5. Joint CompressionUsing·the Lapiplasty® Compressor, bring the precision-cut joint surfaces together for controlled apposition and compression of the arthrodesis site.
6. Multiplanar FixationApply low-profile Biplanar™ Plates dorsally and medially, providing multiplanar fixation for rapid weight-bearing.
