The application of digital design combined with 3D printing technology in thumb reconstruction
Objective An accurate, personal and optimal realization for the choice of donor site area in thumb reconstruction via digital design combined with 3D printing. Methods CT scanning data of both hands and both feet of 7 patients with wounded thumbs were collected. The virtual models of both hands were reconstructed using Mimics. According to the principle that both hands are mirror projection to each other, we can rebuild the mirror image of the uninjured hand in Mimics with one of its features-the mirror option. Thus we could complete the virtual morphological restoration of the defect of the wounded thumb by referring to the mirror projection. Thereafter, using digital virtual comparison and virtual incision, we could get the three-dimensional configuration model of the defect of the thumb. The physical model of the virtual model was produced by using 3D printing technology whereby we could tape the adhesive plaster. Finally, the chosen area of the donor site could be obtained by fixing the taped plaster under the precise direction. Results Totally, the 7 thumb-wounded patients were subject to the digital design combined with 3D printing technology when referring to the choice of their donor site. The physical appearance of the rebuild thumbs were highly resembled to the unwounded state. A rapid restoration of the functions, a favorable effect and a nice feedback from the patients were obtained. Conclusions Digital design combined with 3D printing can make an accurate, personal and optimal decision in the choice of donor site in thumb reconstruction.
