Surgical treatment of Vancouver B periprosthetic femur fracture after total hip arthrplasty
Bibliographic record
Abstract
Objective To investigate the effect of surgical treatment for Vancouver B periprosthetic femur fracture after hip arthroplasty. Methods In the study,50 patients with Vancouver B periprosthetic femoral fractures from July2010 to May 2014 were treated by AO plate fixation,steel strapping and lengthened femoral prosthesis. The effects were evaluated by Harris hip score,bilateral leg length and hip joint activity. Results All the patients were followed up for 6to 28 months( 12. 6 ± 8. 43 months). All fractures were healed well. The Harris hip score was 33. 21 ± 8. 24 before operation,being 69. 75 ± 9. 42,85. 24 ± 7. 25 one week or six months after operation with significant differences( P <0. 05). The shortening length of preoperative limb was 1. 7 ± 0. 8 cm,compared to 0. 6 ± 0. 5 cm six months after operation( P < 0. 05). The range of motion of hip joint were significantly improved after 6 months’ follow-up( P < 0. 05).Conclusions Steel strapping combined with plate fixation for Vancouver B-type periprosthetic femur fracture after hip arthroplasty could achieve satisfactory results.

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.
