Morel-Lavallee Lesion of the Lower Back Mimicking an Abscess: A Case Report
Bibliographic record
Abstract
A closed degloving injury, or Morel-Lavallee lesion, is the result of a severe, traumatic, shearing injury, causing separation of the skin and subcutaneous tissue from the underlying deep fascia. Though well described in the orthopedic trauma literature, this lesion is not well recognized by the general surgeon in the poly-trauma setting. We present a case of a 41 year old man who was referred to the general surgery service for a “back abscess”. Upon patient interview, history of a recent motor vehicle collision (MVC) was obtained, including a pelvic fracture. Imaging demonstrated a large Morel-Lavellee lesion extending from the pelvis into the lower back. Knowledge of this entity is crucial to avoid unnecessary procedures in the management of these patients.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
