Factors Influencing Functional Outcomes in Supracondylar Humerus Fractures: A Retrospective Study of Paediatric Patients in a Level One Trauma Centre

BackgroundThe outcomes after fixation of the supracondylar humerus fracture (SCHF) are not documented in the current literature. In our study, we endeavour to determine the factors that influence the functional outcome and gauge their respective impact.MethodologyWe retrospectively reviewed the outcomes of patients who presented to our tertiary care centre (Royal London Hospital) with SCHFs between September 2017 and February 2018. We analysed patient records to assess several clinical parameters, including age, Gartland's classification, comorbidities, time to treatment, and fixation configuration. We conducted a multiple linear regression analysis to determine each of the clinical parameter's impact on the functional and cosmetic outcome, as reflected in Flynn's criteria. ResultsWe included 112 patients in our study. Pediatric SCHFs had good functional outcomes based on Flynn's criteria. There was no significant statistical difference in functional outcomes with respect to sex (p = 0.713), age (p = 0.96), fracture type (p = 0.14), K-wire configuration (p =0.83), and time elapsed since surgery (p = 0.240). ConclusionsOur results demonstrate that good functional outcomes can be expected with paediatric SCHFs based on Flynn's criteria, regardless of age at injury, sex, or pin configuration, provided satisfactory reduction is achieved and maintained. The only variable with statistical significance was Gartland's grade; Grades III and IV were correlated with poorer outcomes.
