Health-related quality of life after conservatively and surgically-treated paediatric proximal humeral fractures

Purpose The health-related quality of life (HRQoL) after conservatively versus surgically treated paediatric proximal humeral fractures is poorly understood. We assessed the HRQoL after this injury and asked if HRQoL was associated with age, radiological classification or treatment chosen.Methods We identified 228 patients who were treated for proximal humeral fractures between 2004 and 2017. These patients completed the Quick Disabilities of the Arm, Shoulder and Hand (Quick-DASH) (primary outcome), the Paediatric Quality of Life Inventory (PedsQL) and questions regarding patient satisfaction. Fractures were classified radiologically following the Paediatric Comprehensive AO Classification.Results We were able to follow-up on 190 children; 147 (mean age 8.7 years (0.8 to 15.7)) sustained a metaphyseal and 43 (mean age 11.6 years (3.7 to 15.8)) sustained a Salter Harris type I or II injury. Most fractures (90%) were simple, 10% were multifragmentary. In total, 137 children (72%) were treated nonoperatively, 51 (27%) were treated by elastic stable intramedullary nailing (ESIN). After a median follow-up of 7.6 years (0.8 to 14.3) there was an overall mean Quick-DASH of 4.3 (SD 9.3) for girls and 1.2 (SD 3.1) for boys. The mean function score of the PedsQL was 94.7 (SD 11.1) for girls and 98.0 (SD 6.0) for boys. The mean psychosocial score of the PedsQL was 92.0 (SD 11.1) for girls and 94.1 (SD 11.6) for boys. Most children (79%) were very satisfied with the cosmetic result and 74% were very satisfied with the treatment overall. Surgery and female sex were associated with lower satisfaction.Conclusion In this cohort of 190 patients, where immobilization for mildly displaced fractures, and closed reduction and ESIN was used for displaced fractures, there was equally excellent mid- and long-term HRQoL when assessed by the Quick-Dash and the PedsQL.Level of Evidence Therapeutic, Level IV
