Periprosthetic fractures: Treatment with Dall-Miles plates [Fratture periprotesiche: Trattamento con placche Pall-Miles]
Bibliographic record
Abstract
Aim. Periprosthetic fractures pose an increasing challenge to the orthopaedic surgeon as the number total hip replacement operations and revisions continue to rise. The incidence of fractures varies depending on the implantation technique and the quality of the bone where the fractures occur. Methods. From March 2003 to June 2004, 15 patients treated at the Orthopedics and Traumatology Clinic, Genoa, and the Emergency Department of the San Martino Hospital, Genoa, for B1 or B2 periprosthetic fractures (Vancouver classification: 11 type B1, 4 type B2) received a Dall-Miles plate, of which 10 were primary implantations and 5 were revisions; the mean time from surgery to fracture was 4 years (range, 6 months to 12 years). Results. In all patients examined at follow-up, the mean time to fracture union was 4.5 months; the plates were well tolerated and none of them broke. Conclusion. The Dall-Miles plates offer a wide variety of solutions in treating periprosthetic fractures. The cable feedthroughs do not require extensive periosteal stripping, thus preserving the biology of the fracture focus and making the use of allografts or autografts subsequently unnecessary, which, in the authors' opinion and in contrast with the literature, are unneeded in the presence of a stable osteosynthesis.

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.
