Fractures are among the most common injuries in childhood, yet the immature skeleton differs fundamentally from the adult skeleton. A thick periosteum, open physes, and a powerful capacity for remodeling mean that most pediatric fractures unite and realign without surgery. Despite this, national registries document an increasing use of operative fixation, including in some fracture groups with substantial remodeling potential. This narrative review synthesizes the contemporary evidence on the limits within which fractures throughout the growing skeleton can be treated conservatively. The literature was identified through structured searches of PubMed, Scopus, Web of Science, and the Cochrane Library. For each region we summarize the accepted thresholds of angulation, rotation, shortening, and displacement, together with the age- and site-specific modifiers that determine whether a deformity will remodel, and we present these thresholds in comparative tables. We also delineate the genuine indications for surgical treatment, so that the boundary between conservative and surgical management is defined rather than blurred. A secure command of these region-specific limits lets the treating physician exploit the child's remarkable remodeling potential and avoid both under- and over-treatment.
