Automated Screw Planning for Reduced Pelvic Fractures Based on Statistical Shape Models and Deep Learning

Read the original on arXiv AI →

The article presents a fully automated pipeline for preoperative iliosacral screw planning in pelvic fracture patients, utilizing patient-specific 3D anatomy to identify safe screw corridors and generate individualized insertion trajectories. In a study of 200 clinical cases, the automated method increased the safety margin of safe insertion corridors by 2% across four screw types, reduced mean planning time by over 90%, and achieved a 95% clinical acceptance rate compared to conventional manual measurements.

GUMP-Net: An interpretable model-data-driven intelligent algorithm for multi-class pelvic segmentation

Pelvic segmentation is one of the most important and fundamental research problems in precise and intelligent diagnosis and treatment, as well as surgical planning and navigation for pelvic fractures. By combining an improved geodesic active contour model with deep neural networks, we propose GUMP-Net, an interpretable model-data-driven intelligent algorithm for multi-class pelvic segmentation, in which three network modules are designed to constitute the overall segmentation framework together: the object detection module for automatic level set initialization, the edge detector module for learning an anatomy-aware edge detector function and the iteration module for deep level set evolution.

THA-Flow Generative Model: Prosthesis Geometry Prediction from Preoperative CT

THA-Flow is a conditional flow-matching model that generates 3‑D prosthesis geometry directly from preoperative CT scans for total hip arthroplasty. It uses separate AutoencoderKL models to compress bone anatomy and prosthesis shapes, and a 3‑D UNet to learn a flow from Gaussian noise to the prosthesis latent space conditioned on bone geometry. In a retrospective cohort of 1,355 hips, the model produced accurate acetabular and femoral geometries for 93.4% of cases, preserving component position and alignment while allowing limited local variation.
