Efficacy of sacroiliac corticosteroid injections in patients with inflammatory spondyloarthropathy: results of a 6 month controlled study.
Bibliographic record
Abstract
OBJECTIVE: To evaluate changes in articular symptoms, spinal mobility, and global function over 6 months after intraarticular injections of long acting corticosteroid into the sacroiliac (SI) joints of patients with inflammatory low back pain (ILBP). METHODS: Nineteen patients with symptoms of ILBP were studied. Thirteen (68%) had radiographic evidence of sacroiliitis. The remaining 6 patients (32%) had normal imaging studies and thus were considered to have mechanical low back pain. All patients received bilateral SI joint injections of triamcinolone hexacetonide (40 mg/joint) under computer tomographic guidance. Outcome variables included the duration of low back morning stiffness, back pain (by visual analog scale, McGill Pain Questionnaire), spinal mobility (chest expansion, Schober test, 10 cm segments test, finger-fibula distance), and self-report health status (SF-36). RESULTS: Both groups of patients showed a transient improvement in stiffness and pain, spinal mobility, and general health status that was most pronounced at 1-3 months after intraarticular therapy. This did not reach statistical significance (p > 0.05) and by 6 months, followup all outcome variables had reverted to pretherapy levels in both groups. CONCLUSION: These preliminary observations suggest that SI corticosteroid injections are ineffective in the management of patients with inflammatory spondyloarthropathy.

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.
