Minimal intervention (removable splint or bandage) for the management of distal forearm fractures in children and adolescents: A scoping review.

INTRODUCTION: Distal forearm fractures are common in children and adolescents with a spectrum of severity. There are fracture patterns that are suitable for minimal interventions, such as a splint or bandage. The objective of this review was to identify which types of paediatric distal forearm fractures can be safely and effectively managed with a removable splint or bandage.

MATERIALS AND METHODS: A scoping review was performed. Databases searched were PubMed, Embase, The Cochrane Library and CINAHL; two trial registries were also searched. All primary study designs with children <18 years of age with a distal forearm fracture that was managed in either a splint or bandage were included. Quality of evidence was determined using the GRADE tool.

RESULTS: Twenty-two eligible articles were included from 20 unique studies: 12 randomised controlled trials, seven cohort studies and a case report. Twelve studies focused solely on buckle/torus fractures, with remaining studies including other fracture types, such as incomplete ('greenstick'), complete ('transverse'), or physeal (Salter-Harris). Twelve studies reported that participants with either bandage or splint had appropriate reduction in pain and recovery of function at completion of follow-up for all fracture types. All 20 studies reported minimal adverse events related to fracture management. One study reported worsening angulation with bandage immobilisation for complete fractures in two participants, which required manipulation under anaesthesia.

DISCUSSION: There is high quality evidence to support the safety and effectiveness of a splint or bandage for treatment of distal radius buckle and non-displaced incomplete fractures. Several studies supported the use of minimal interventions for various distal radius cortical breach fracture types, with good outcomes, but were limited by heterogeneity (methodology, interventions, outcome measures, reference standard) and potential bias.

CONCLUSIONS: Included studies confirmed the inherent stability of buckle fractures. The current literature gap to support minimal interventions for a range of other paediatric distal forearm fracture types was highlighted. High-quality evidence with well-designed, large, multicentre randomised control trials in defined age groups is required to identify which paediatric distal forearm fractures can be safely and effectively managed with either a removable splint or bandage.
