ABSTRACT
PURPOSE: The aim of this study was to analyze an injury scene during fly fish boat riding (FBR).METHODS: We conducted survey on 12 patients who had humerus shaft fractures during FBR between 2011 and 2016 at three university-based emergency rooms. Individual information, injury mechanism, classification of humerus shaft fracture, and combined injury were recorded from medical document and telephone interview.RESULTS: The injury happened when the kite was turned over and fall into the water in 10 patients (82%); the kite was turned over in the air in one patient (9%), and a leash between kite and boat was broken in one patient (9%). All patients showed 12-B1 or 12-B3 type distal humerus shaft fracture. And there were combined contralateral distal humeral shaft fractures in two patients, vertebral compression fracture in one patient, and radial nerve injury in four patients.CONCLUSION: Riding position and injury mechanism such as turning over may affect distal humerus shaft fractures with butterfly fragment during FBR.
