Hey David,
I try not to jump in on bracing conversations too much because it is obvious that I am going to be biased. And to be honest, a lot of the guys on here that have been through an injury (like M-Dizzle and the others above) usually answer the questions really well and say basically the same stuff I would say. That being said, I did want to address a couple points that came up:
1. If your insurance will cover a custom Bledsoe (or Donjoy, or Breg, Etc) it will also cover a CTi. Same for OTS (off-the-shelf) braces. All those custom braces bill under the same code for customs or the same code for OTS braces.
2. Doctors choose to prescribe different brands for different reasons. Some have a good relationship with that brand's sales rep or they may just prefer their overall breadth of products. A lot of things can factor in on why they choose their bracing partner. BUT... even if a doctor is a "Bledsoe guy", he can still prescribe a CTi. It is a matter of you asking for a CTi and educating them on the demands of your sport and why a CTi will function better for your needs. Most doctors will try and get their patients (you) what they want as long as you can help them understand why you want it. We actually provide sport-specific sellsheets (including wakeboarding/wakeskating) on our website to help this process.
www.ossur.com/cti under the "support documents" tab. You can bring it in to help educate your doctor on why the CTi functions better for your needs.
Sorry if it comes across as me trying to hard sell on CTi. That is not my intent. I just try to provide information that I would want if I were investigating the subject. Thanks again to all the guys that take the time to jump on here and help out.
Good luck with your rehab and with whatever brace you end up getting!
