This was probably the worst skating accident I've seen on TV. During the failed lift, he (as trained) attempted to break her fall
Copied the below from Wikepedia.
On September 29, 1999, Binnebose fell while lifting Handy and hit his head on the ice, suffering a skull fracture and brain injury.[1][2] He had emergency brain surgery and was put in an induced coma.[2][3] His heart also stopped twice but he was brought back and gradually began to recover.[2] Binnebose was released from hospital on November 30, 1999.[1] His accident and recovery was featured on the Discovery Health Channel television series Impact: Stories of Survival. As of 2010, he continued to suffer facial paralysis and other effects of the injury but had returned to the ice and was teaching skating.[2]

I vaguely recall a fluff piece about skaters wearing helmets - perhaps after isabell brasseur had a fall. The skaters said it hindered their peripheral vision as well as impacting their balance during jumps and spins. The helmet would add to outside forces on the head during rotations. Helmets only help the outside of the head - not the jarring that occurs inside.
As others have pointed out, reducing the rotations and/or speed would save the athletes, but it would also kill the sport.
My friend's daughter was hit in the head by a softball - fortunately it wasn't a line drive. I believe it was from a foul tip on a ball. Total freak accident. She had a mild concussion and was not allowed to do anything jarring for at least 2 weeks. She definitely had sensitivity to noise and light for a couple of days.
My other friend's daughter fell off a rock climbing wall. Her spotter's finger got pinched which caused her to let loose. The young lady had a concussion and a couple of fractured vertebrae but no paralysis. She's expected to make a full recovery as long as she takes things easy to let her body heal. For the 1st several weeks, she could pretty much only lay there and after a while do quiet things like knitting - any bright images or noise were abrasive for several weeks, reading was a struggle. For a girl who was on track to graduate from Cornell a semester early, she hated doing nothing. About a month afterwards, she could only go to noisy events if she wore headphones that muffled the noises around her. It's been a struggle for her to slow her life down to allow herself to heal ... and she's not an competitive athlete dependent on being able to move.....
So, I can imagine that most athletes probably shorten their recovery time unless there's someone in their lives that are willing to interecede.
