Intramedullary Delivery of Local Antibiotics Via Calcium Sulfate Beads for Chronic Osteomyelitis With a Simple, Novel Surgical Technique
Bibliographic record
Abstract
Aim: The aim of this manuscript was to describe a novel surgical technique that can be used intraoperatively to aid in the management of chronic diaphyseal osteomyelitis through the delivery of antibiotics into the medullary canal. Technique: Following standard intramedullary and reamer irrigator aspirator preparation of the femoral canal, a negative-pressure gradient is created through the canal. A 32-Fr chest tube is placed antegrade down the femur and used as a conduit for delivering antibiotic beads. A 20-Fr chest tube can be used to manually piston the beads further down the canal. Uses, Outcomes, and Pitfalls: This technique can be used to administer prefabricated calcium sulfate antibiotic beads or hand-made antibiotic polymethylmethacrylate beads evenly throughout the medullary canal of long-bones. It is a simple, cost-effective, one-surgery solution to assist clinicians when managing patients presenting with this difficult problem.

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.
