InCore™ Lapidus System

InCore Ad_new2

The InCore Lapidus System is a three-part construct intended for internal fixation for First Tarsometatarsal Fusion.

This system is internal to the bone, minimizing the need for hardware removal due to pain and irritation reported with traditional external plating constructs of first tarsometatarsal arthrodesis.1

Features of targeting guide:

  • Stabilizes correction in all three planes (transverse, sagittal, and frontal planes)
  • Provides distraction of joint for visualization and joint preparation
  • Intended to aid and hold pre-compression of joint
  • Simplifies the technique with fully-guided steps

Tri-Planar Correction

  • Targeting Guide is intended to aid and stabilize angular/rotational correction in all three planes (transverse, sagittal and frontal plane)

Fully Guided

  • Post and Targeting Guide utilize anatomical land marks to facilitate fixation placement
  • Angular correction of the metatarsal facilitated and maintained by the targeting guide

Solid Intermedullary Construct

  • Solid 5.9mm Titanium Post provides large surface area engagement in the cancellous bone of the medial cuneiform
  • Headless compression screws thread directly into the 5.9mm post
    • Post and screws construct may reduce hardware prominence and resultant hardware removal due to pain or irritation related to such hardware prominence. Hardware removal due to pain and irritation is reported in up to 17% of first tarsometatarsal arthrodesis cases when using plating constructs1,2

Joint Preparation

  • Targeting Guide provides distraction of the joint for visualization and joint preparation
  • Distraction allows space for curettage and microfracture

Controlled Compression

  • Targeting Guide includes built-in Compression-Distraction Fixture providing compression parallel to the long axis of the first metatarsal


  • 5.9mm x 28mm Titanium Post
  • 3.5mm Diameter Headless Compression Screws offered from 24 to 56mm in length
  • Robust T10 Hexalobe Driver
