Sacral Epidural Abscess Complicating Closed Sacral Fracture
Bibliographic record
Abstract
In Brief Objective. To describe the clinical course of the development of an epidural abscess with a rare localization. Summary of Background Data. Epidural abscess usually presents with severe back pain and neurologic deterioration. Spinal fracture may lead to the development of epidural abscess. To the author’s knowledge, this is the first reported case of epidural abscess following sacral fracture. Materials and Methods. The patient was observed closely in the hospital after a sacral fracture with bilateral S2, S3 dermotome numbness. Fever, bacteremia, and urinary tract infection developed. Fever responded partially with antibiotics. Results. Sacral laminectomy for decompression was performed. Unexpectedly, sacral epidural abscess was found during the operation. Sacral roots were decompressed. Epidural abscess was drained. Conclusion. A rare case of sacral epidural abscess following sacral fracture was reported. It is a case report of a 44-year old intravenous heroin abuser who suffered from epidural abscess after a closed sacral fracture. The potential problems in diagnosis and the possible implications of sacral epidural abscess are discussed.

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.
