Abstract
Objective To discuss the treatment options and clinical results of Vancouver B periprosthetic femoral fractures following hip arthroplasty.Methods 21 patients with Vancouver B periprosthetic femoral fractures treated in the affiliated hospital of Qingdao university medical college from 1998 to 2011 were retrospectively reviewed.Among them,12 cases were type B1 fractures,6 cases were type B2,3 cases were type B3 according to Vancouver classification,which were implemented treatment according to the prosthesis stability fracture fixation treatment or prosthesis revision surgery.The rehabilitation of patients in follow-up study were evaluated,and the treatment results were reviewed and analysed.Results All patients were followed up with an average of 5.2 years.Type B1 fractures healing rate was higher,but we need to pay attention to the length of the fixed plate and the reduction of fractures.The successful revision surgery is the key point of the treatment of type B2 fracture.In complicated B3 fractures,high failure rate was noted.Conclusions Femoral periprosthetic fractures of hip arthroplasty are difficult.Thus,the prevention is particularly important.The choice of treatment depends on the fracture site,implant stability and bone defects.The appropriate treatment and surgical techniques are the keys for the treatment of the fractures,therefore considerate algorithm of preoperative planning for these diseases is very important.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
