Rock-paper-scissors-OK game for neurological examination in pediatric supracondylar humerus fractures: A prospective randomized controlled trial.

Purpose: Pediatric supracondylar humerus fractures frequently involve nerve injuries, which can be difficult to assess before and after surgery. This study evaluated a smartphone application that teaches nerve examination to children using a rock-paper-scissors-OK game, and assessed its effects on examination time and satisfaction. Methods: In this single-center, prospective randomized controlled study, 102 children aged 4-10 years who underwent surgical treatment were randomized into 2 groups. Group 1 learned nerve examination through the classical method taught by orthopedic residents and a specialist. Group 2 was taught using the smartphone application with the game. Pre- and postoperative nerve examination times were recorded. Child and parent satisfaction were measured with the Child HCAHPS questionnaire. Results: Mean preoperative examination time was shorter in group 1 (4.3 ± 1.3 min) ( Conclusions: A smartphone-based rock-paper-scissors-OK game improves postoperative nerve examination efficiency and increases satisfaction, particularly regarding communication and information sharing. Level of evidence: Level II.
