Spontaneous Resolution of Quadrilateral Space Syndrome
Bibliographic record
Abstract
A case of quadrilateral space syndrome is presented, where a large near-circumferential glenoid labrum tear led to a paralabral cyst that dissected into the quadrilateral space and caused a compressive neuropathy of the axillary nerve. This led to a 6-mo history of left shoulder pain, parasthesias, marked weakness to abduction, and marked denervation in both the deltoid and teres minor on electro-diagnostics. This is a presentation of interest as it is the only case report in the literature, to the authors' knowledge, where spontaneous resolution of entrapment occurred. This normally requires intervention for definitive management. It resolved through nonsurgical management with pregabalin, oxycodon, and naproxen medications, leading to good functional return, as well as pain and presumed muscle edema dissipation, while awaiting interventional consultation. It also illustrates that quadrilateral space syndrome is a difficult clinical diagnosis owing to the nonspecific symptom presentation, as well as weakness.

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.
