please help me with this question Zoran Solano, a 20-year-old man was brought into the Emergency Department (ED) after an accident whilst riding on an electric scooter. He was stabilised and transferred to the Orthopaedic Ward for surgery in the morning. BACKGROUND Zoran Solano was out partying with his friends, celebrating a birthday in the Valley. According to his cousin, Eyad, Zoran started drinking at 5pm that day and by the time they left the club around 2am, Zoran was very intoxicated. As they were walking out of the club, Zoran decided to jump on an electric scooter that was parked outside the club. Eyad started running after Zoran, and he saw Zoran weaving in and out of cars on the road at a high speed. Eyad saw Zoran barely manage to avoid fully hitting the concrete column of a building but he jumped off the electric scooter and landed in an awkward position.
