A study published in 2026 in the Journal of Children’s Orthopaedics followed 140 proximal radius fractures in 138 children and sought to understand which initial characteristics were associated with complications and less favorable outcomes over time [1].
The minimum follow-up was 5 years, and for re-evaluated patients, the median reached almost 7 years [1]. This case series is therefore useful for looking beyond just initial radiographic healing.
A primary displacement of at least 3 mm was associated with a higher risk of complications, with an odds ratio of 6.7 [1]. Physeal involvement and a higher Judet class were also associated with a less favorable course. These are elements that help distinguish fractures with a more benign prognosis from those that warrant greater attention.
The choice between immobilization, closed reduction, internal fixation, or open reduction remains important, but the study suggests that a significant part of the prognosis is already linked to the initial severity of the injury [1].
Worse functional outcomes were more frequent in surgically treated cases [1]. This data does not demonstrate an unfavorable effect of surgery: in a retrospective study, operated children are likely those with more severe, displaced, or unstable fractures upon presentation. This is the classic confounding by indication.
In the initial assessment, I would therefore pay particular attention to the actual displacement, physeal involvement, and Judet classification. These elements can influence both treatment and how we set up follow-up and counseling.
The study does not provide an automatic threshold for surgery. Rather, it identifies initial characteristics associated with a higher risk, which must be integrated with age, stability, possibility of reduction, and clinical picture.
The study is retrospective and from a single centre, with not entirely standardized protocols and a proportion of patients lost to follow-up [1]. However, the number of cases and the duration of observation remain strengths for a relatively uncommon injury.
Initial displacement, physeal involvement, and Judet class therefore help define the risk already at the first evaluation. Two fractures, both described as "proximal radius fractures," can have a very different course.
