Non-operative treatment versus suture refixation of the nail plate in paediatric fingernail avulsion injuries.

Abstract

The study compared a non-operative treatment, consisting of ointment dressing only, with the standard surgical nail plate refixation for simple fingernail avulsion injuries in children. A non-inferiority hypothesis was tested in a single-centre, prospective cohort study. The quality of the new nail was the primary outcome and was assessed with the Nail Appearance Score. The secondary outcome was patient and parental satisfaction, which was assessed with the Patients' and Parental Nail Satisfaction Score. Fifty-one patients were enrolled; 39 (76%) chose the non-operative treatment and 12 (24%) the standard operative therapy. Comparison of the two groups confirmed the non-inferiority hypothesis with a risk difference for the new nail of -0.02 with a 95% confidence interval of (-0.05, 0.01). The outcome was excellent in all fingers with no significant differences regarding either the primary or secondary outcome. In view of associated risks and costs for surgery, we recommend ointment dressings for such injuries.<b>Level of evidence:</b> II.
