If you want to know whether Dr. Betz is reliable or not, ask these questions during your consultation.
There is no way anyone can get accurate facts about any doctor unless you gather all his previous patients(which is impossible)
Also being shown some patients who say good about the result should not add to the credibility of this doctor when you have a consultation. Bear this in mind.
You can decide it for yourself.
1. Tell him that you are recording this consultation just to be safe. (this is very important. imagine something happens later and you don't have a proof that you've been misled. And he should agree to this if not.... well.)
2. Ask him which company manufactures the Betzbone.(its name and location)
a) its material
b) whether it has any government-body approval on it or CE marking like Guichetbone
U.S FDA approved Precice nail and its manufacturer is Ellipse technology(which you can google and find out)
AND NOT about pending Patents. Pending patents does not mean it is medically safe. You can request patents for something that goes into iPhone.
c) its weight bearing capacity and THE SOURCE OF that claim.(if he cites his own blah, ask for the documentation)
also the extent of the weight bearing capacity.
3. The rate of complication for cosmetic limb lengthening by dr. Betz. Have it written down with his official signature.
Bending, breakage. etc... also separate by categories 11mm,13mm , men or women, femur or tibia... with which nail, albizzia or betzbone...
AND it does not matter if he says the reasons for most complications were due to the patients, if the number is high itself. that means he was not careful in satisfactorily informing the patients. (there is no way you can trust what I say but I second that claim the complication rate is closer to 30~40% for all his patients...)
if he can't answer to #2, then this question about complication rate and official documentation shouldn't be a problem unless there IS a problem)
4. if you can speak German, ask around in the hopsital he practises, not the Komfort Clinic(it is not a medical clicnic but rather a private hotel with nurses equipped placed next to a real hospital). Well, if you can ask like five doctors, do it. also even if remotely related to orthopedics.
ASK THIS "IN YOUR OPINION, IS DR BETZ AN ETHICAL DOCTOR?".
they are on his payroll... so just watch their reaction. If Dr.Betz is a great doctor as is claimed by so many on the diary, The reaction should be very uniformly warm and blah even though they do not agree with the idea of cosmetic limb lengthening.)
It is a big surgery and if he does not want to give you satisfactory asnwers... for that matter any doctors doing this procedure, just skip that doctor. The doctors should have no problem giving you asnwers unless he wants to hide something.
Also if you have the money to do internals with DR.Betz, surely you can afford Dr. Guichet or even DR.Paley. I can't say which one is an ethical doctor but please do have consultations with all of them. And also dont forget to ask whether prospective doctor has treated any complication case from other doctors(also details about them)
Best wishes.
