“…A meta-analysis by Zhang [ 8 ] of nine case-control studies consisting of 638 patients concluded that 3D printed bone models for surgical planning in pelvic and acetabular fractures resulted in a statistically significant reduction in surgical time, blood loss and the likelihood of inadequate fracture reduction compared to conventional imaging-based planning techniques. Similar benefits have been reported by various authors in smaller case series [ 7 , 9 – 15 ] with minor variations in the techniques.…”

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.

“…For example, 3D printing assisted surgical technique would be preferred for these types. [28] It is difficult to be sure, but one would hope that the advances made during this time have led to improvements in outcome and that if modern-day techniques had been available to Letournel, even better results would be seen. [16] Letournel pointed out that clinical outcomes are better than radiological ones.…”

BACKGROUND: This study aims to evaluate the surgical approaches, complications, clinical and radiological findings in acetabular fractures treated with surgical methods and to determine the parameters affecting prognosis. METHODS:Out of 144 patients undergone surgical treatment with the diagnosis of displaced acetabular fractures between 1994 and 2014, a total of 103 patients with 75 male and 28 female with a mean age of 36.3 years (range 19-67 years) whom clinical and radiologic follow-ups (mean: 34 months, range 2-8 years) were performed at least for two years were included in this study. RESULTS:Clinically excellent to good outcomes were obtained in 64% of the patients and moderate to poor outcomes were recorded in 36% of the patients, while radiologically excellent to good outcomes were achieved in 57.3% of the patients and moderate to poor outcomes were recorded in 42.7% of the patients. Presence of one of the complications, creating mechanical block (chi-square p<0.001), complex fractures (chi-square p=0.023), increased duration between trauma and operation (p=0.039), operational time taking longer than six hours (chi-square p<0.001), more than 3 mm intra-articular step (Fisher's p=0.033), avascular necrosis (p<0.001), arthritis (p=0.006) and heterotopic ossification (p=0.007) worsened the clinical outcomes (chi-square p<0.001). The age of the patient was not effective on the clinical outcome (p=0.461). CONCLUSION:It was found that three major parameters affecting the prognosis of acetabular fractures are as follows: type of fracture, operational time and reduction quality. The duration between trauma and operation indirectly affects the outcomes. Avascular necrosis, heterotopic ossification and arthritis may cause negative effects only on long term outcomes.

“…This 3D-printed replica is used for pre-contouring the plate by assuming body symmetry [ 16 , 17 , 18 , 20 , 21 , 22 , 25 , 27 , 28 , 35 , 36 , 37 , 38 , 39 , 40 ]; Virtual model of injured bone/zone is reconstructed and then 3D-printed. Surgeons use this tangible model to perform reduction and then to pre-contour the plate [ 13 , 14 , 15 , 19 , 29 , 33 , 41 ];…”

“…Blood loss can be better managed when using 3D printing models. Several studies reported consistent reduction of blood loss (e.g., [ 13 , 16 , 33 ]), while others note the reduction as not significant [ 30 , 31 ]. The accuracy of acetabulum fracture reduction is reported to be similar or slightly better in cases using 3D-printed models for plate contouring (e.g., [ 20 , 30 , 31 ]).…”

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.
