Combining 3D printing technology with customized metal plates for the treatment of complex acetabular fractures: A retrospective study.
Article in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposesThe purpose of this study is to evaluate the clinical outcomes of combining 3D printing technology with customized metal plates in the treatment of complex acetabular fractures.
methodsA retrospective study was conducted on 42 patients with complex acetabular fractures treated at our hospital between September 1, 2020 and May 31, 2022. The patients were divided into two groups: the conventional group and the 3D printing group, with 21 individuals in each group.The conventional group underwent surgery using traditional surgical techniques, with appropriate bending and adjustment of the metal plates during the procedure. In the 3D printing group, preoperative 3D printing technology was utilized to create a physical model of the fracture, and individualized metal plates were customized based on the model after virtual reduction. Comparison was made between the two groups of patients regarding surgical approach, operative time, instrument handling time, intraoperative blood loss, number of fluoroscopy scans, fracture healing time, quality of fracture reduction postoperatively, hip joint function at 12 months postoperatively, and occurrence of complications during the follow-up period.
resultsThe 3D printing group showed significantly shorter surgical time (124.76±12.89 minutes vs. 174.05±12.51 minutes), instrument operation time (44.57±5.32 minutes vs. 62.9±7.47 minutes), intraoperative blood loss (337.38±51.95 mL vs. 545.24±74.39 mL), and intraoperative fluoroscopy frequency (8.25±1.18 times vs. 10.52±1.6 times) compared to the conventional group (P<0.001). The postoperative fracture reduction quality in the 3D printing group was good in 95.24% (20/21) of cases, significantly higher than the 61.90% (13/21) in the conventional group (P = 0.02). The excellent and good hip function rate in the 3D printing group was 90.48% (19/21), which was also significantly higher than 57.14% (12/21) in the conventional group (P = 0.01). No significant difference was observed between the two groups in fracture healing time (13.95±1.07 weeks vs. 13.81±1.17 weeks) and complication rate (9.52% vs. 28.57%) (P = 0.14; P = 0.24).
conclusionThe application of 3D printing technology in conjunction with individualized customization of metal plates for the treatment of complex acetabular fractures can shorten surgical and instrument handling time, reduce intraoperative blood loss, and improve the quality of fracture reduction as well as the recovery of hip joint function.These results provide new insights and technical support for the treatment of complex acetabular fractures.
