Casting Without Reduction Versus Reduction With or Without Fixation for Mildly Displaced Paediatric Distal Radius Metaphyseal Fractures: A Randomised Noninferiority Trial
Journal of Pediatric Orthopaedics · 2 Nov 2026
† Impact is the editorial-priority score. All scores are out of 100. Clinical is how far this paper should move patient care if its methods hold up; it does not measure the size of a treatment benefit.
Why it matters
Paediatric distal radius fractures are the most common childhood fracture, and knowing when remodelling makes reduction unnecessary can spare young children anaesthesia, pins, and their complications.
The evidence
This single-centre randomised trial in Colombia compared casting without reduction against closed reduction under general anaesthesia (with K-wires if unstable) in 60 children aged 5 to 10 with mildly displaced distal radius metaphyseal fractures. At 6 months, PROMIS upper-extremity function was essentially identical (mean difference -0.03 points, 95% CI -4.71 to 4.65), within the prespecified -5 point noninferiority margin. Two serious anaesthetic complications occurred only in the reduction group. The trial enrolled less than half of its planned 126 children.
A coherent primary effect estimate is unavailable. Clinical relevance does not estimate treatment benefit.

Study design sets the starting point and a ceiling of 96. Recorded methods then adjust the score. Points are shown to one decimal place; the final score uses unrounded values.
Checklist from the stored appraisal. “Not met” describes the recorded criterion; it does not always produce a deduction. This overview supports reading the full study.
How the clinical score was reached
The question: 8/9. Three judgements of how much it matters to patients, which decision it informs and how closely it fits their care.
Patient consequence: moderate (2/3). A patient-experienced outcome of real but smaller or shorter-lived importance: early pain or function, speed of recovery, return to sport or work, minor complications, satisfaction, or a validated score at a short time point.
Decision relevance: high (3/3). The study compares the actual options a clinician chooses between (or a whole strategy), and its primary result directly indicates which to choose, or that they are interchangeable. A clinician could act on it without a further translation step.
Applicability: moderate (3/3). A recognisable practice population, but with a notable restriction: narrow eligibility, a single expert surgeon or centre, or an unusual protocol that would need adapting. Applicability only subtracts for a real mismatch, so moderate counts in full.
What it found: Points one way (×0.86). A verdict without a usable interval, a clear result from a trial the paper itself calls underpowered, or a review whose certainty is low or unrated. No primary interval or verdict was extracted, so this answer is the appraisal's own judgement of the paper, held to the same power and certainty rules.
The design ceiling: 85. The most a rct can score here, however relevant its question and clear its answer.
Clinical = 85 × 8/9 × 0.86 = 65.
For journal club
1.For a 7-year-old with a distal radius metaphyseal fracture angulated 18 degrees, how would you counsel the family about casting in place versus reduction under anaesthesia, including expected remodelling and anaesthetic risk?
2.Would these findings change your approach for a 10-year-old near the upper age limit, or for a fracture with combined shortening and complete displacement, and what follow-up would you plan to catch loss of position?
