Comparison of Two Treatment Methods for Vancouver B1 Periprosthetic Femoral Fractures
Bibliographic record
Abstract
Objective: To investigate the clinical effect of shape-memory embracing fixator or locking compression plate(LCP) and cable on the treatment of vancouver B1 periprosthetic femoral fractures(PPF). Methods: Retrospective analysis of two groups of patients treated with either shape-memory embracing fixator(5 cases) or locking compression plate and cable(7 cases) was performed.The operation time, bleeding,Harris score,healing time and expenses were recorded and statistically compared.Results: The post-operative follow-up lasted 6-26 months.There were no differences between the two groups in operation time and bleeding,but statistical differences were found in Harris score and healing time.Although the LCP and cable is more expensive than embracing fixator,patients in LCP and cable group got earlier bone healing.Conclusion: The most important procedure of treatment for B1 PPF is rigid fixation of proximal femur,which contains prosthesis,and the LCP and cable method is preferred.

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.
