Abstract
BACKGROUND: Arthroscopic and open Bankart repairs have proven efficacy in adults with recurrent anterior shoulder instability. Although studies have included children in their analysis, none have previously compared functional outcomes or redislocation rates between these 2 methodologies for anteroinferior glenoid labrum repair in this young population. We hypothesize that open and arthroscopic Bankart repair in children will have similar functional outcomes and redislocation rates, but differing results from adults treated in a similar manner. METHODS: A retrospective chart review was performed on all Bankart repairs performed between 2006 and 2010 at a tertiary care children's hospital. A shift in treatment modalities occurred in 2008 creating 2 cohorts, open and arthroscopic. Brachial plexus injury, congenital soft-tissue disorder, or incomplete charts were excluded. Demographics, age at surgery, follow-up length, and sport were recorded. Telephone interviews were then performed obtaining the most current QuickDASH (Disability Arm, Shoulder, or Hand), WOSI (Western Ontario Shoulder Instability Index), SF-12 (Short Form 12), SANE (Single Assessment Numeric Evaluation), and verbal pain scores; as well as, inquiring about recurrent dislocation and further surgery. RESULTS: Ninety-nine children (16.9±1.5 y) were included (28 open, 71 arthroscopic). There were no differences in preoperative demographics. Fifty-one patients completed the questionnaires (11 open, 40 arthroscopic). No significant differences in the outcomes scores were seen between the 2 groups. Of the 99 patients, 21 (21%) had redislocation or secondary surgery; there was no significant difference in failure rate between groups (4 open, 17 arthroscopic). A plotted survival curve demonstrated that the adolescent shoulder undergoing Bankart repair for recurrent traumatic anterior instability has a 2-year survival of 86% and a 5-year survival of only 49%, regardless of technique. CONCLUSIONS: In adolescents, there is no significant difference in functional outcomes or redislocation rates between open and arthroscopic Bankart repair, yet both demonstrate a very high risk of failure in this young, athletic population which contrasts the results in the historic adult population. LEVEL OF EVIDENCE: Level III-retrospective comparative study.

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 it
