Can A Clavicle Be Lengthened 12 cms If Done Enough Times?

Q: Dr. Eppley, Is it possible to extend the collarbone 3 or 4 times for a total of 12cm or 16cm? I want to get an extension effect of 12cm or more through at least 3 surgeries. Is it possible if there is enough time and rehabilitation?

A: Such a degree of clavicle lengthening (12 to 16cms) is not possible no matter how many times it is done. The tight shoulder girdle and scapula is the limiting factor which provides a ‘stop’ as to how much push the extended clavicle can be allowed to go..
