Diaphyseal fractures of the radius and ulna in children can be treated with reduction and casting or, in selected cases, with internal fixation using TEN/ESIN. Both strategies generally lead to healing and good functional outcomes; what differs most is the stability of the treatment course. [1–4]
A meta-analysis published in 2025 in JPOSNA included 24 studies and 1,157 patients with diaphyseal fractures of both forearm bones. Healing was 100% in both the surgical and conservative groups. [1]
Stability and Redisplacement
In the conservatively treated group, overall complications were more frequent: 24% versus 12%. Redisplacement was reported in 26% of cases treated with a cast and 3% of those who underwent surgery; additional procedures were also more common in the conservative group. [1]
This does not mean that casting is an absolutely inferior treatment. In young children, with a stable fracture and good remodeling potential, it often remains the most proportionate choice. The main limitation is the possibility that an initially acceptable reduction may progressively lose alignment.
What TEN/ESIN Offers
Elastic stable intramedullary nailing (ESIN) stabilizes the fracture and reduces reliance on maintaining reduction within the cast. In older children, adolescents, and unstable fractures, this can simplify follow-up and reduce the risk of needing further treatment. [1,4]
A prospective randomized trial from 2025 compared children treated with ESIN with or without postoperative immobilization. In the non-cast group, the callus score was better at early follow-ups and quality of life at 6 weeks was superior, without an increase in complications in the studied sample. [2]
A retrospective series of 173 patients treated with ESIN without postoperative casting reported complete healing and a low rate of major complications. [3]
These data do not prove that casting after TEN is useless in every situation, but they show that stable fixation can allow for more flexible postoperative management.
The Choice Depends on Fracture Type and Age
In young children, a well-reduced and stable fracture can be treated very effectively with a cast. As age increases, the remodeling potential decreases, and a loss of reduction or residual malrotation becomes less tolerable.
TEN/ESIN therefore gains more importance when the fracture is unstable, when reduction tends not to be maintained, or when age makes spontaneous remodeling less reliable.
Immobilization and Daily Life
Part of the benefit of internal fixation is not visible on the final X-ray alone. Reducing or avoiding a postoperative cast can mean less stiffness, simpler hygiene, and an easier recovery in the first few weeks.
However, this benefit must be weighed against anesthesia, surgical wounds, possible problems with the nails, and a subsequent hardware removal.
For diaphyseal fractures of the radius and ulna, the useful question is not which technique "heals all fractures better." It is about understanding in which cases casting offers sufficient stability and in which cases internal fixation avoids a more uncertain course.
