Abstract

fetched live from OpenAlex

The significant rate of recurrent instability following arthroscopic stabilization surgery points to a need for an evidence-based treatment approach. The Instability Severity Index Score (ISIS) is a point-based algorithm that may be used to assist clinicians in selecting the optimal treatment approach, but its efficacy has not been previously validated in a controlled study. We aim to compare two surgical treatment algorithms: the ISIS Score and a conventional treatment algorithm (CTA). This was a prospective, randomized controlled trial involving 63 participants who underwent a shoulder stabilization procedure. Participants were randomized to either the ISIS or CTA and were followed for 24-months post-randomization. Mean age was 31.8 years (range 18-62) and 66% of the cohort was male. The primary outcome was the Western Ontario Stability Index (WOSI). Secondary outcomes included the American Shoulder and Elbow Surgeons (ASES) score as well as recurrence rates between groups. Sixty-three patients were randomized to ISIS (n=33) or CTA (n=30). The WOSI score was similar for the ISIS 84.3±21 and CTA 83.4±14.5 groups (p=0.89). Similarly, no differences were detected between the ASES (90±22.4 and 91.2±11.2 for the ISIS and CTA groups respectively (p=0.87). Apprehension was reported in 10% of participants in each group (p=1.00). At 24-months follow up, there were no re-dislocations in either group. There was one revision surgery in the ISIS group due to graft failure and two in the CTA group. No statistically significant differences in functional outcomes, the incidence of apprehension, or failure rates were identified between the two treatment algorithms at 24-month follow-up.

Not 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.
