Key's been a bit absent, but
his clinic updated their blog last month with his progress pics. Allow me to translate.
Text basically compares ISKD and Precice, noting that the latter is better in every way -- like its reverse mechanism -- except for its higher cost. Turns out that Key was well-read and approached Dr. Ito if he could get Precice, even though the clinic didn't publicly offer it. Luckily the doctor was familiarized with Precice, as he had recently visited the US for additional training, and heard a lot of praise about the device.
As Key mentioned, NuVasive representatives told the doctor he was the first to perform limb lengthening with Precice in Japan. NuVasive reps were present for the procedure.
Photos are from seven weeks post-op, shows a 3 cm increase in femoral length of the left leg. His bow legs are improving as well. Doctor notes that Key is working while lengthening.
They're aiming for at least a 5 cm final distraction. The post ends with a box of snacks from Key to the staff as a token of appreciation (common gesture in Japan).
There is
one more older post, lot of the same info about Precice, but there's a video of Key doing his lengthening with the external remote controller (ERC). He adds an interesting note, saying that he's utilizing the
Baumann procedure (Baumann is also cited in the
official Precice ducumentation, page 8), and believes that lengthening to 8 cm is possible.
