“…3D printing rationalises virtual 3D planning by enabling surgeons to tactilely feel real-sized models where scale, shape and anatomy are more effectively appreciated and collision between bone fragments is well represented [ 4 , 5 ]. Models manufactured with materials fulfilling biocompatibility standards such as ISO-10993 can be sterilised following predefined protocols [ 6 ] and brought to the surgical field.…”

Surgical applications of three-dimensional printing in the pelvis and acetabulum: from models and tools to implants

There are numerous orthopaedic applications of three-dimensional (3D) printing for the pelvis and acetabulum. The authors reviewed recently published articles and summarized their experience. 3D printed anatomical models are particularly useful in pelvic and acetabular fracture surgery for planning, implant templating and for anatomical assessment of pathologies such as CAM-type femoroacetabular impingement and rare deformities. Custom-made metal 3D printed patient-specific implants and instruments are increasingly being studied for pelvic oncologic resection and reconstruction of resected defects as well as for revision hip arthroplasties with favourable results. This article also discusses cost-effectiveness considerations when preparing pelvic 3D printed models from a hospital 3D printing centre.

“…Several limitations still remain to be addressed. According to expert surgeons and the literature, some drawbacks are still acceptable as long as the main geometry of the bone fracture is kept within the gold standard and the discrepancy errors of virtual reduction are less than 2 or 3 mm [12,37]. Even though mesh defects can be removed by using the proposed method, future work needs to be implemented to reduce the computing time for detecting and removing overlapping meshes.…”

Development of Mesh-Defect Removal Algorithm to Enhance the Fitting of 3D-Printed Parts for Comminuted Bone Fractures

Purpose Mesh self-intersection defects and image noise may prevent 3D model reconstruction and mesh formation of bones with comminuted fractures, making it impossible to assemble 3D-printed fragments perfectly. This study proposes an algorithm to remove overlapping meshes and to smooth fracture surfaces in order to fabricate well-assembled 3D-printed bone. Methods 3D bone reconstruction, segmentation, and reduction were directly performed for three different classes of clinical fracture cases: pelvic 62-B1, 62-C2, and femur 31-A2.2. In contrast to the current Boolean operation, the proposed algorithm is not only capable of detecting overlapping meshes, but also recognizing the contact regions and detecting the boundary of each contact region. Hence, it was implemented in order to remove overlapping meshes and ensure that fragments fit together when physically assembled. Both gap distance and overlapping mesh errors during assembly of the 3D model from printed bone fragments were calculated and analyzed. Results and Conclusions Based on the comparison of results between the bone model before and after removing mesh defects, the RMS error is less than 0.33 mm and gap error is 3 mm, indicating that the proposed technique has high potential for eliminating mesh defects and providing a 3D-printed bone fracture model that is easy to assemble and disassemble.

“…In orthopedic surgery, tangible 1:1 models of patient anatomy allow better visualization, which is very important for evaluating complex fracture patterns. 3D-printed bone replicas are also helpful in measuring screw lengths, in choosing the fixation plates or implants, and precontouring (pre-shaping) the fixation plates [ 6 , 12 ].…”

“…There are many reviews addressing the applications of 3DP technology in medicine, and in particular for orthopedic surgery [ 4 , 5 , 6 , 10 , 12 ]. However, a detailed analysis of the use of 3D-printed models for precontouring orthopedics fixation plates has not been performed so far, to the authors’ knowledge.…”

This paper is a systematic review of the literature on 3D-printed anatomical replicas used as templates for precontouring the fixation plates in orthopedic surgery. Embase, PubMed, Cochrane, Scopus and Springer databases were consulted for information on design study, fracture anatomical location, number of patients, surgical technique, virtual modeling approach and 3D printing process. The initial search provided a total of 496 records. After removing the duplicates, the title and abstract screening, and applying exclusion criteria and citations searching, 30 papers were declared eligible and included in the final synthesis. Seven studies were identified as focusing on retrospective non-randomized series of clinical cases, while two papers presented randomized case control studies. Two main approaches were highlighted in developing 3D-printed anatomical models for precontouring fixation plates: (a.) medical reconstruction, virtual planning and fracture reduction followed by 3D printing the model; (b.) medical reconstruction followed by 3D printing the model of the mirrored uninjured side. Revised studies reported advantages such as surgical time and blood loss reduction, while the reduction quality is similar with that of the conventional surgery. During the last couple of years there was an increase in the number of studies focused on precontouring orthopedic plates using 3D printing technology. Three-dimensionally-printed templates for plate precontouring were mostly used for acetabular fractures. Knowledge on medical virtual modeling and reconstruction is mandatory.
