Abstract

fetched live from OpenAlex

This study evaluated the effectiveness and safety of bone growth stimulation using combined magnetic field (CMF) for the treatment of fracture nonunions. In this prospective multicenter study, patients were assessed monthly for 9 mo, or until they demonstrated a healed nonunion, and were assessed at a final follow-up 3 mo after treatment completion. The primary outcome was the presence or absence of fracture healing at the nonunion site, determined by clinical and radiographic assessment. Enrolled in this study were 112 patients with 116 fracture nonunions. Fifty-two (44.8%) patients demonstrated a healed nonunion between treatment initiation and 12-mo- posttreatment initiation (9 mo of treatment plus 3 mo posttreatment follow-up). Tibial nonunions had a higher percentage of healed fractures compared to other fracture types (78% vs. 46.5%, respectively; p = 0.004). This study demonstrated that noninvasive CMF technology healed 78% of tibial fracture nonunions and 45% of all fracture nonunions (p = 0.004). Additionally, pain at rest, with stress, and on weight bearing all decreased following treatment with CMF, with no adverse events reported. These results indicate that CMF is a beneficial noninvasive treatment modality for nonunions.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
