Hi, my stepdad needs surgery to fix some screws in his lower spine that have come loose and they are affecting the nerves etc he lives in Saskatoon Sask Canada. His family Dr. is recomending a Dr in Alberta because he said not all Surgeons will fix this problem because screws are not used anymore to fix spinal injuries. This surgery he had that they put the screws in was done in Mexico as he fractured vertebrae after falling off a chair that broke. he is going to be 80 in august and has no quality of life at all because of the pain he is in I want names of other Dr s as the Dr that was reccommended I ve done a little research and don t feel comfortable with there has got to be other Dr s in Canada that do surgery on existing loose screws in the back Thank you please help
