Predictors of outcomes of proximal humerus fractures in children and adolescents: A systematic review.

Abstract

Purpose:Minimally displaced pediatric proximal humerus fractures can be reliably managed non-operatively; however, there is considerable debate regarding the appropriate management of severely displaced proximal humerus fractures, particularly in older children and adolescents with limited remodeling potential. The purpose of this study was to perform a systematic review to answer the questions: “What are the functional and quality-of-life outcomes of pediatric proximal humerus fractures?” and “What factors have been associated with a poorer outcome?”Methods:A review of Medline and Embase was performed on 4 July 2021 using search terms relevant to proximal humerus fractures, surgery, non-operative management, pediatrics, and outcomes. Studies including ≥10 pediatric patients with proximal humerus fractures, which assessed clinical outcomes by use of an established outcome measure, were selected. The following clinical information was collected: participant characteristics, treatment, complications, and outcomes.Results:Twelve articles were selected, including four prospective cohort studies and eight retrospective cohort studies. Favorable outcome scores were found for patients with minimally displaced fractures, and for children aged less than 10 years, irrespective of treatment methodology or grade of fracture displacement. Older age at injury and higher grade of fracture displacement were reported as risk factors for a poorer patient-reported outcome score.Conclusion:An excellent functional outcome can be expected following non-operative management for minimally displaced pediatric proximal humerus fractures. Prospective trials are required to establish a guideline for the management of severely displaced proximal humerus fractures in children and adolescents according to fracture displacement and the degree of skeletal maturity.Level of evidence:level V.
