Abstract
Accurately positioning components during radial head arthroplasty is difficult due to the complex shape of the radial head. The objective of this study was to develop a navigation system for patient-specific radial head implants using intra-operative surface-based registration techniques. Using an optical tracking system, an implant stem was navigated using real-time visualisation of the implant position and orientation (n = 8). Absolute positioning errors in the ML and AP directions were 0.8 ± 0.5 mm (and 1.1 ± 0.9°) and 0.8 ± 0.6 mm (and 1.2 ± 1.7°), respectively. Registration error was less than 1.0 mm. The current system is an important first step in the development of a computer-assisted system for implant navigation.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
