Background Three‐dimensional (3D) printing has seen increasing interest in surgery, where it improves the visualization of difficult anatomy in complex cases. This literature review investigates the benefits and limitations of 3D printed models in preoperative planning in the field of orthopaedic surgery. Methods A literature search was performed using the Ovid platform on the Embase and MEDLINE databases using the terms ‘3D printing’, ‘Orthopaedics’ and ‘Surgical Planning’. Studies using 3D printed models as a part of preoperative planning were included. All others were excluded. Data regarding the metrics used to assess the benefit of the use of 3D models, surgical outcome, and surgeon or patient opinion on the technology were extracted. Results A total of 41 studies resulted. Eight (19.5%) were case–control studies, the remainder were case reports or case series. Assessment of benefit was mostly subjective, although the case–control studies included objective metrics such as operation time, intraoperative blood loss and intraoperative fluoroscopy time. The use of 3D printing technology showed subjective benefit for both patient and surgeon as well as indicating clinically significant improvements in intraoperative metrics. Conclusion Despite the current absence of large scale trials, 3D printing has clear benefits in preoperative planning, particularly when utilized in complex cases. A streamlined workflow for case selection, in‐house model creation and preoperative rehearsals is still required to be developed before the process is ready for routine use. Evidence supports an improvement in intraoperative metrics and patient engagement but data to support improved clinical outcome is lacking.

“…Huang et al [23] demonstrated that 3-D printing technology increased the predictability, accuracy and reliability of both-column acetabular fractures reduction.Wang reported that, compared with CT images or humerus-subtracted volume renderings,the 3-D-printed model was able to represent the glenoid bony morphology accurately and clearly which facilitated shoulder surgeons to perform preoperative planning [24]. A double-blinded randomized clinical trial indicated that osteotomy simulation on the 3-D-printed pelvis models for DDH patients increased the success rate of the operation and shortened surgery time ,as well as promoted postoperative recovery [25].Xu et al [26] recommended the use of the 3-D printed model before THA in DDH patients due to better preoperative planning and intraoperative orientation,as well as surgical outcomes.Our study demonstrated the high agreement between the size of the acetabular cup and bone defect of simulated operations on 3-D printing models and the actual size used in the operations.…”

Abstract Background It is technically challenging to restore hip rotation center exactly in total hip arthroplasty (THA) for patients with end-stage osteoarthritis secondary to developmental dysplasia of the hip (DDH) due to the complicated acetabular morphology changes.In this study, we developed a new method to restore hip rotation center exactly and rapidly in THA with the assistance of three dimensional (3-D) printing technology. Methods Seventeen patients (21 hips) with end-stage osteoarthritis secondary to DDH who underwent THA were included in this study. Simulated operations were performed on 3-D printed hip models for preoperative planning. The Harris fossa and acetabular notches were recognized and restored to locate acetabular center. The agreement on the size of acetabular cup and bone defect between simulated operations and actual operations were analyzed.Clinical and radiographic outcomes were recorded and evaluated. Results The sizes of the acetabular cup of simulated operations on 3-D printing models showed a high rate of coincidence with the actual sizes in the operations(ICC value = 0.930) There was no significant difference statistically between the sizes of bone defect in simulated operations and the actual sizes of bone defect in THA( t value = 0.03,P value = 0.97). The average Harris score of the patients was improved from (38.33 ± 6.07) preoperatively to the last follow-up (88.61 ± 3.44) postoperatively.The mean vertical and horizontal distances of hip rotation center on the pelvic radiographs were restored to (15.12 ± 1.25)mm and ( 32.49 ± 2.83) mm respectively. No case presented dislocation or radiological signs of loosening until last follow-up. Conclusions The application of 3-D printing technology facilitates orthopedists to recognize the morphology of Harris fossa and acetabular notches, locate the acetabular center and restore the hip rotation center rapidly and accurately.

“…Zengy et al (11) suggested that the 3D reconstruction technique may restore the true acetabular morphology and allows for quantitative analysis of DDH patients. Of note, a pilot study demonstrated the potential application of the rapid prototyping pelvic model for patients with DDH, which facilitates arthroplasty planning and surgical procedures due to better planning and improved orientation (12).…”

Developmental dysplasia of the hip (DDH) is a congenital or developmental deformation of the hip joint, which may require a high number of surgical interventions. It has been indicated that 3D printing may be used to simulate a fractured pelvis to facilitate the fixation of plates during the surgical procedure. In the present double-blinded randomized clinical trial, the utility of the 3D-printed pelvis model, comprising 3D reconstruction, reverse engineering and rapid prototyping, in the treatment of DDH was evaluated with 3D CT as control. The value of the 3D-printed pelvis model in the surgical management and development of a strategy for an individualized operation for DDH using osteotomy simulation was also assessed. The results indicated that use of the 3D-printed pelvis model increased the success rate of the operation with a shortened surgery time and post-operative recovery time for DDH patients. In addition, the application of the 3D-printed pelvis model allowed for more efficient surgical management of DDH than 3D CT and promoted post-operative recovery of the DDH patients. Pre-operative planning using the 3D-printed pelvis model was feasible for DDH patients. Furthermore, few patients exhibited delayed incision healing, wound infection or nonunion in the DDH group with osteotomy simulation using the 3D-printed pelvis model or 3D-CT. In conclusion, the present study indicated that the 3D-printed pelvis model, including 3D reconstruction, reverse engineering and rapid prototyping, constitutes an efficient tool for pelvic osteotomy simulation, which improves personalized pre-operative planning by providing a visual and accurate osteotomy model for patients with DDH (Chinese Trial Registry No. KCT0012374).
