[Treatment of Vancouver type B1 periprosthetic femoral fracture with locked plate and xenogenic bony plate].
Bibliographic record
Abstract
OBJECTIVE: To analyze the therapeutic effect of plate cable system and cortical strut bone graft in the prosthesis revision of the total hip arthroplasty for the treatment of Vancouver type B1 periprosthetic femoral fracture. METHODS: A total of 8 patients were selected from January 2006 to January 2013, including 6 males and 2 females, aged from 56 to 74 years old (62.52 years old on average). All the cases were treated by the long plate cable system and appropriate cortical strut bone graft. Harris score was used to evaluate the hip functions before and after the operation. Prosthesis stability and the bony union were assessed by the digital radiography. RESULTS: All the patients were followed up for 45 months on average ranging from 24 to 60 months after operation. All the fractures reached union, and there was no infection, stem loosening, nonunion and malunion. The Harris score was 28.45±5.78 before operation, which was improved to 83.46±10.21 after operation. X ray showed that the prosthesis was stable, and the host bone and bone graft achieved bony union in 7 patients;and the other 1 patient need further operation of revision around the loose stem. CONCLUSIONS: The prosthesis revision of the total hip arthroplasty with the locking plate and cortical strut bone graft used for the Vancouver type B1 periprosthetic proximal femur fractures has the advantages of simple manipulation, less complications, good recovery of the hip function and can improve bone quality to provide favorable conditions for operation of revision.

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.
