CLINICAL EXPERIENCE WITH OSIGRAFT IN ITALY: MULTI-CENTER, OBSERVATIONAL STUDY
Bibliographic record
Abstract
BMPs, among which BMP-7 or OP-1, unlike several growth factors involved in new bone formation, are the only proteins able to start the whole process. That is BMPs are the only factors with osteoinduction ability. Contrary to other growth factors, BMPs on the market are drugs. RhOP-1, carried by collagen type 1, is the first osteo-inductive drug approved in the world for the clinical usage: in long-bone non-unions in US, Australia and Canada and in tibia non-unions, recalcitrant to autograft, in Europe (Osigraft). We report data related to a retrospective observation on some patients treated in Italy with rhOP-1. 90 patients (66 with long-bone non-union diagnosis, 8 with delayed union, 7 with bone defect /bone cyst and the remaining with other pathologies) are reported, and efficacy results are showed on 60 patients with follow-up > 6 months. Radiographic analysis shows that rhOP-1 is effective in 86,6% of patients. Unions have been reported in 34,8% at 4–5 months, and in 69,1% at 6–8 months. Failure: 8/60 (13,4%). No adverse event has been reported. These data are similar to those reported in literature in randomised and not randomised studies.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
