Summary
Personalized 3D printed dynamic anterior plate-screw systems for the quadrilateral area (DAPSQ) offer reduced operation time and blood loss in treating acetabular fractures compared to traditional plates.
Area of Science:
- Orthopedic surgery
- Biomedical engineering
- Trauma care
Background:
- Acetabular fractures require precise surgical reconstruction for optimal outcomes.
- Traditional reconstruction plates may present challenges in achieving accurate fit and fixation.
- Advancements in 3D printing technology offer potential for personalized surgical implants.
Purpose of the Study:
- To compare the clinical efficacy and safety of a 3D printed DAPSQ plate versus a traditional DAPSQ reconstruction plate.
- To evaluate surgical outcomes, including operative time, blood loss, and complication rates.
- To assess the accuracy of implant placement and hip function post-surgery.
Main Methods:
- Retrospective case-control study of 43 patients with double-column acetabular fractures.
- Comparison between 20 patients treated with a 3D printed DAPSQ plate and 23 with a traditional DAPSQ reconstruction plate.
- Evaluation of surgical data, implant positioning, reduction quality (Matta score), and hip function (modified Merle d'Aubigné score).
Main Results:
- The 3D printed group demonstrated significantly shorter operation times (223.2 vs 260.5 min) and less intraoperative blood loss (930.4 vs 1426.1 mL).
- Implant position and length in the 3D printed group closely matched preoperative planning.
- No significant differences were observed in reduction quality, hip function, or overall complication rates between the groups.
Conclusions:
- Personalized 3D printed DAPSQ plates show potential advantages in reducing surgical time and blood loss for acetabular fracture treatment.
- The 3D printed implants facilitated accurate placement according to preoperative planning.
- Further research may explore long-term outcomes and broader applications of 3D printed implants in acetabular surgery.
