It was the week before Christmas and Emily Greenwood had just finished a celebratory dinner with friends.

As the pedestrian light turned green on the corner of Addison and Enmore roads in Marrickville, Ms Greenwood took one step out onto the road.

Just as her foot hit the bitumen, a cyclist ran a red light and collided with her, leaving Ms Greenwood unconscious, fracturing her collarbone and knocking out several front teeth.

The 24-year-old nurse woke up hours later in hospital with stitches in her lip and swelling all over her body, along with the pain of an estimated $15,000 medical bill, mostly in dental fees.
