Why perform the LAPIPLASTY® Procedure?

Because metatarsal frontal-plane rotation matters

While 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.1 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.2,3,4 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 innovative approach to anatomic bunion correction

The new, patented LAPIPLASTY® System is designed to deliver unmatched control and reproducibility to 1st TMT fusion by accurately positioning the metatarsal in anatomic alignment (including frontal-plane rotation), performing precision joint cuts with the correction held in place, and easy-to-apply multiplanar tension-side fixation.


Make your correction before you cut
The LAPIPLASTY® Positioner is engineered to quickly and reproducibly close the IM angle and de-rotate the metatarsal, thus establishing and holding true anatomic alignment of the metatarsal and sesamoids.


Perform precision cuts with confidence
The LAPIPLASTY® Cut Guide delivers precise, parallel cuts with the metatarsal held in the corrected position, ensuring optimal cut trajectory while virtually eliminating the risk of metatarsal shortening.


Apply multiplanar fixation with tension-side support
Low-profile BIPLANAR™ Plating with the anatomic PLANTAR·PYTHON® Plate provides multiplanar stability and easy-to-apply plantar plating, using standard-sized locking screws to accommodate anatomic variations without the need for intra-operative measuring.
