Minimally Invasive Approach for Complete Resection of a Cervical Intramedullary Tumor via a Dorsal Root Entry Zone Using Fixed Tubular Retractor
Bibliographic record
Abstract
We describe the surgical aspects of the resection of a large 2cm intramedullary ependymoma at the C6-7 level associated with an extensive syrinx using a unilateral minimally invasive approach through a fixed tubular retractor. A gross total resection was achieved. Total operative time was 5 hours. Estimated blood loss was less than 100 cc. Postoperative evolution was favorable, with the improvement of the patient's neurological status. There was no cerebrospinal fluid (CSF) fistula. Hospital stay was four days. All narcotics were stopped on day 1 after surgery. Post-operative MRI showed no residual tumor. At the six-month follow-up, there was continued improvement in his neurological status. Scoliosis films did not reveal any cervicothoracic kyphosis.
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.
