Lily-Nicole Robinson is believed to have been walking home to Batemoor when she was in a collision with a vehicle close to Meadowhead Roundabout on Saturday evening.
The 27-year-old teaching assistant remains in hospital awaiting surgery after two bones were broken in one of her legs and her back was also broken in two places.
Her mum Joanne and grandmother Christine say they are still in the dark about exactly what happened that evening as Lily-Nicole has been heavily dosed up with painkillers and unable to provide any information.
They said they had heard nothing from police and felt like they were in ‘no man’s land’ regarding the crash.
Joanne said: “We’re trying to piece together what happened, and we’d urge anyone who knows anything to contact police.”
Christine said: “She’s in a bad way in hospital and she hasn’t been able to tell us anything because she’s been dosed up with morphine. We’ve not heard anything from the police and we feel like we’re stuck in no man’s land.”
A South Yorkshire Police spokeswoman said: “We received a report just after 6.30pm on Saturday, May 22. It is reported a pedestrian was in a collision with a vehicle on Bochum Parkway, Sheffield. The female pedestrian was taken to hospital by ambulance with a broken leg.”
Anyone with information is asked to call police on 101, quoting incident number 803 of May 22.
