Background:
Given the novelty of three-dimensional (3D) printing-assisted fracture surgery in orthopaedics, surgeon familiarity is limited and learning curve is high. As such, it is unclear how the introduction of 3D printing into clinical practice for pelvic and acetabular fracture surgery would impact perioperative outcomes. The aim of this study was to determine the impact of introducing 3D printing-assisted surgery on perioperative outcomes for traumatic pelvic and acetabular fractures.
Methods:
We retrospectively identified consecutive patients who underwent surgical fixation of traumatic pelvic and acetabular fractures from 2018 to 2022 at a single tertiary hospital. The patients included in the study were divided into two groups: (1) 3D printing-assisted surgery and (2) conventional surgery. Baseline demographics and perioperative outcomes of total surgical duration, estimated blood loss, blood transfusion, number fluoroscopy images, fluoroscopy duration and postoperative disposition were recorded and compared between the two groups.
Results:
In total, 26 patients were included in the present study, with 3D printing-assisted surgery being used in 34.6 % (n = 9) of cases. There were no significant differences in baseline demographics or fracture type between the 3D printing group and conventional group. As compared to patients who underwent conventional surgery, those that underwent 3D printing-assisted surgery had, on average, shorter surgical duration (299.8 ± 88.2 vs 309.1 ± 143.1 min), lesser estimated blood loss (706.3 ± 330.0 vs 800.0 ± 584.2 ml), lower transfusion rates (50.0 % vs 52.9 %), lower number of intraoperative fluoroscopy images (62.8 ± 74.5 vs 71.6 ± 47.9 images) and shorter fluoroscopy duration (235.0 ± 79.2 vs 242.3 ± 83.5 min), although statistical significance was not achieved. None of the patients in the present study developed surgical complications postoperatively.
Conclusion:
The introduction of 3D printing-assisted surgery in clinical practice for pelvic and acetabular fractures is a safe and viable adjunct in pelvic and acetabular surgery, achieving comparable perioperative outcomes in the initial phase.
