3D-printed haptic 'reverse' models for preoperative

by:Tuowei     2019-06-09

In reconstruction surgery, preoperative planning is critical for optimal functional and aesthetic outcomes.

Create a Threedimensional (3D)model from two-dimensional (2D)

Rapid prototyping imaging data has been used in industrial design for decades, but has not been introduced into medical applications until recently.

3D printing is a fast, convenient and relatively cheap technology.

In this report, we introduce a production 3D-

Printed reverse model for flap design and harvesting representing skin wound defects.

This includes an 82-year-

After continuous soft tissue removal from wound infection, an elderly person exposed to an ankle prosthesis.

Soft tissue coverage and death

Space filling with composite forearm free flap (RFFF).

Computed tomography angiography (CTA)

Place of donation (left forearm)

, Recipient site (right ankle)

Had surgery on the left ankle.

The 2D data of CTA is 3D-

Reconstructed with computer software, using 3D images of the left ankle as a control.

Create a 3D model by stacking left and right ankle images to create a reverse image of the defect and print it using a 3D printer.

Therefore, RFFF is effectively planned and executed without complications.

As far as we know, this is the first report on the mechanism for calculating soft tissue wound defects and generating 3D models that may be useful for surgical planning.

3D printing, especially reverse modeling, may be a variety of options in reconstruction planning, with a wide range of application potential. ?
