The Implant Looks Plausible but Cannot Be Placed
A zero-shot audit found no implantable output from three released shape-completion models across 239 cranial defects.
Summary
A zero-shot audit found no implantable output from three released shape-completion models across 239 cranial defects.
Researchers tested three pretrained shape-completion systems on 210 synthetic cranial defects and 29 real post-craniectomy cases. None of the zero-shot outputs both avoided intersecting remaining bone and added useful material; a task-specific volumetric model was implantable on all but one case. The authors also warn that point outputs do not encode implant thickness. The audit does not rule out future models or specialist workflows, but it shows that visually plausible completion is not enough for clinical use.
