Complex joint-preserving bone tumor resection and reconstruction using computer navigation and 3D-printed patient-specific guides: A technical note of three cases

Clinical applications and prospects of 3D printing guide templates in orthopaedics

“…ABS and PLA are suitable for some large guides, such as percutaneous spinal guides [ 44 ]. The resin can be used for positioning guidance for lower limb osteotomy and deformity correction [ 45 ]. Nylon has high precision and high strength, so it is recommended to be used for guide plates with small volume and certain strength requirements like total knee arthroplasty [ 40 , 46 ].…”

“… Year Authors Journal Case number Type of surgery Results 2021 Wong KC et al. [ 45 ] Journal of orthopaedic translation 3 Using both Computer Navigation and Patient-Specific Guide for bone sarcoma patients who underwent joint-preserving bone tumor resections and reconstruction The mean maximum deviation errors of the nine achieved bone resections were 1.64 ​± ​0.35 ​mm. The histological examination of the tumor specimens showed negative resection margin.…”

“…When the resection is geometric with multiple osteotomy planes, the current 3D printing surgical guides may be superior to the computer navigation in bone tumor resections. With the combined techniques in complex joint-preserving bone tumor resection, more conservative bone resections that preserve native joints and ligaments may be achieved for reconstruction with a better limb function [ 45 ].…”

Case Report: 3D-Printed Prosthesis for Limb Salvage and Joint Preservation After Tibial Sarcoma Resection

“…With the PSG perfectly conforming to anatomical structures, it was unnecessary to measure the distance during the operation, therefore, reducing the risk of manual errors and the operation time, especially in complex multiplanar bone resections. And the introduction of computer navigation techniques to verify the correct placement of PSG intraoperatively rendered a more precise safe margin ( 40 ). However, there are concerns about 3D printed prostheses and PSGs before widespread clinical use.…”

Continued improvement of translational medicine – A cohesive approach

“…Wong et al. present a computer navigation and 3D printing solution that may result in least tissue loss with total tumour resection [ 1 ]. Similarly, Xu et al.…”
