Just got back from visiting her.
She, as is common, has no recollection whatsoever. However, witnesses suggest the traffic was stopped, she was slowing but still rolling and a driver turning either collected her, or she ran into.
Her helmet bore the brunt of most of the impact, a few dents and one slight crack to the rear. On all appearances, it looked like a concussion with some unconsciousness. The ambos, as is their procedure, gave her the full spinal immobilisation for transport. And, alas as indicated above, her spine took the rest of the impact her helmet didn't. 3 ribs, 4 vertebrae cracked, one of which is 'burst', which isn't good. It's likely she hit the gutter.
Upon reaching the Alfred, concussion was still the suggestion but after x-rays they saw the severity. It's highly likely if she hadn't been immobilised the 'burst' vertebra would have damaged her spinal column.
So, she now has a nice zipper from her neck to half way down her back, and the x-ray looks like something from Terminator 2. That'll be there forever - holding 6 vertebrae immobile. She's more flexible than I thought she'd be, and already coming off some of the drug dosages. The staples from her neck will likely come out Friday.
And yes, she has full intention of getting back on the bike to commute, although she asked me if I thought an orange safety flag was too much. I don't.
