Abstract
QUESTION: Do dynamic splints reduce contracture following distal radial fracture? DESIGN: Assessor-blinded, randomised controlled trial. PARTICIPANTS: Forty outpatients with contracture following distal radial fracture. INTERVENTION: The control group received routine care consisting of exercises and advice for 8 weeks. In addition to routine care, during the day the experimental group received a dynamic splint, which stretched the wrist into extension but allowed intermittent movement. OUTCOME MEASURES: The primary outcomes were passive wrist extension and the Patient Rated Hand Wrist Evaluation (PRHWE). The secondary outcomes were active wrist extension, flexion, radial deviation, and ulnar deviation, and the performance and satisfaction items of the Canadian Occupational Performance Measure (COPM). All outcomes were measured at commencement, at the end of 8 weeks of treatment, and at 12 weeks (ie, 1 month follow-up). RESULTS: The mean between-group difference for passive wrist extension and PRHWE at 8 weeks were 4 deg (95% CI -4 to 12) and -2 points (95% CI -8 to 4), respectively. The corresponding values at 12 week follow-up were 6 deg (95% CI 1 to 12) and 2 points (95% CI -5 to 9). There were no sufficiently important between-group differences for any of the secondary outcome measures at 8 or 12 weeks. CONCLUSION: It is unclear whether dynamic splints following distal radial fracture have therapeutic effects on passive wrist extension or PRHWE, but they clearly do not have any therapeutic effects on active wrist extension, flexion, radial or ulnar deviation, or on the performance or satisfaction items of the COPM. The ongoing use of dynamic splints following distal radial fracture is difficult to justify. TRIAL REGISTRATION: ACTRN12608000309381.

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
