IMPROVED SHOULDER RANGE OF MOTION AND EARLIER RETURN TO WORK OCCURS FOLLOWING OPEN REDUCTION AND INTERNAL FIXATION OF HUMERAL DIAPHYSEAL FRACTURES
Bibliographic record
Abstract
Recovery from injury, including pain-free range of motion (ROM), is important for return to work and function. This study aimed to evaluate the return of shoulder, elbow, and forearm range of motion (ROM) following a humeral diaphyseal fracture. This is a prespecified secondary analysis from a large randomized controlled trial (RCT) comparing open reduction and internal fixation (ORIF; plates and screws) with non-operative treatment (functional bracing) of humeral diaphyseal fractures. Standardized ROM measurements for the shoulder, elbow, and forearm were taken using a goniometer at 6 weeks, then at 4-, 6-, and 12-months post injury. Patient-reported return to baseline level of work was assessed at each follow-up. T-tests and a two-way ANOVA (time and treatment group) were used to compare between the treatment groups. A total of 168 patients were enrolled (n=84 per treatment group), with an 85% 1-year follow-up rate. The ORIF treatment group demonstrated significantly improved ROM over time for shoulder abduction (p = ± 71.7) days, compared to those in the non-operative group, at an average of 138.3 (± 98.1) days (p = 0.005). Return to work and function are important to stakeholders including patients, their family members, and their employers. This large RCT provides return to function and work information that can help guide shared decision making between patients and surgeons, as earlier recovery of ROM and return to work were demonstrated in the ORIF treatment group.

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.
