“…Personalized, minimally invasive, and accurate operations are a future development direction of clinical treatment. [9][10][11][12] However, as a new and challenging area of research, few recent papers have focused on this topic. Jiménez-Delgado et al stated that, to the best of their knowledge, there were no computer-assisted methods to plan an entire fracture reduction process.…”

Background Long bone fractures are a type of physical damage with high incidence rates that have serious impacts on the normal lives of humans. Aims How to obtain a preoperative internal fixation plate model before cutting muscle has become a critical issue. Materials and Methods In this paper, we present a new personalized modeling system for internal fixation plates in long bone fracture surgery. This system can achieve straight semi‐automatic processing from CT images to 3D models. First, broken bones are separated in CT images. Second, the axes of long broken bones are extracted using 3D models. Third, the vertices on the broken bone cross‐sections are segmented. Fourth, rough alignment and fine registration are implemented. Results An internal fixation plate is reconstructed for a long bone fracture. Discussion Three validations indicate that this method framework is reasonable and feasible. Conclusion This system can provide technical support for the personalized, minimally invasive and accurate operation on long bone fractures.

El riesgo de presentarse algo diferente a lo planeado, por ejemplo, no lograr una reducción anatómica, modificaría completamente la planeación preoperatoria.…”

Despite the increasing use of 3D printing in orthopedic surgery, there is no established method for the validation of a printed bone model. A printing error could potentially lead to complications, especially when the model is used for surgery planning. We aimed to validate a series of 33 acetabular fractures with a novel method by detailed analysis of model errors.After applying a surface filter on both the patients model and the 3D printed model, a two-step registration consisting of landmark-based pre-registration and ICP-registration, was slightly varied and conducted 100 times, yielding a mean surface deviation and standard deviation for each model surface point.We furthermore showed that more than 30 random ICP-registration points lead to a sufficiently good registration, and that the variation of the pre-registration is small enough to guarantee a stable ICP registration result.Deviations caused by failed registration are unveiled by a large standard deviation of the 100 registration routines. For the fracture series, the mean surface deviation error between the printed model and the patient model was less than 1 mm (median = 0.7 mm; 95% CI = 0.68-0.72 mm). The largest errors were found in areas with remaining support structure material, on printbed-facing model sides and on abrasive surface regions. By visualizing the residual registration error, it was possible to clearly detect surface deviations and to quantify them.

Three-dimensional printing and patient-specific pre-contoured plate: future of acetabulum fracture fixation?

Abstract: Patient-specific pre-contoured plate made using 3D model is a better implant than intra-operatively contoured plate. Real-time 3D pelvis model is an accurate technique for pre-operative planning in acetabular fractures.
