Clinical Applications of 3‐Dimensional Printing Technology in Hip Joint

Abstract

Three‐dimensional (3D) printing is a digital rapid prototyping technology based on a discrete and heap‐forming principle. We identified 53 articles from PubMed by searching “Hip” and “Printing, Three‐Dimensional”; 52 of the articles were published from 2015 onwards and were, therefore, initially considered and discussed. Clinical application of the 3D printing technique in the hip joint mainly includes three aspects: a 3D‐printed bony 1:1 scale model, a custom prosthesis, and patient‐specific instruments (PSI). Compared with 2‐dimensional image, the shape of bone can be obtained more directly from a 1:1 scale model, which may be beneficial for preoperative evaluation and surgical planning. Custom prostheses can be devised on the basis of radiological images, to not only eliminate the fissure between the prosthesis and the patient's bone but also potentially resulting in the 3D‐printed prosthesis functioning better. As an alternative support to intraoperative computer navigation, PSI can anchor to a specially appointed position on the patient's bone to make accurate bone cuts during surgery following a precise design preoperatively. The 3D printing technique could improve the surgeon's efficiency in the operating room, shorten operative times, and reduce exposure to radiation. Well known for its customization, 3D printing technology presents new potential for treating complex hip joint disease.

Prediction of the Size of the Fragment in Comminuted Coronoid Fracture Using the Contralateral Side: An Analysis of Similarity of Bilateral Ulnar Coronoid Morphology

“…The application of 3D-printed, personalized prosthesis is a new breakthrough in 3D printing technology, which has been used to replace or restore the osseous structure or normal function. Currently, published results have suggested its application in spine, hip, knee, and elbow, which has indicated an optimistic outlook [21][22][23][24] . It was believed that postoperative function of the joint and the longevity of the 3D printing prosthesis were closely associated with precise measurement of the anatomical parameters.…”

Customised three-dimensional printed revision acetabular implant for large defect after failed triflange revision cup

“…Developments in bioengineering and biotechnology now make it possible to close this gap even in cases of severe bone defect and damage. 15 This technique was completely unknown before, but now it is becoming more available for difficult cases; however, it is an expensive method and not convenient to use in every centre. It is important that the modern orthopaedic surgeon has full knowledge of this technique and can keep in reserve for difficult cases.…”

Global trends in the development of complex, personalized, biomedical, surgical implant devices using 3D printing/additive manufacturing: A review

“…The examples shown in Figures 4 and 5 represent extent of clinical trials which began in China nearly a decade ago. While the US has performed similar trials nationwide, China has become a world leader in innovative and complex bone replacement surgeries as illustrated for example in Figure 5 (Cai, 2015;Xia et al, 2019). China has also embarked on programmes to manufacture SLM and EBM systems and Gadia et al, 2018;Huang et al, 2019;Kalaskun, 2017;Lee et al, 2020;Murr, 2019Murr, , 2020Tofail et al, 2018;Wohlers Report, 2019, 2019Woo et al, 2020;Zhang & Chen, 2019).…”
