Does Morphine For Back Pain Cause Spinal Scoliosis?

I have been taking morphine for back pain for many years. In 1998 I had to have my left hip replaced. In 2009 a Lt knee replacement,2010,rt knee replacement, but my knees were totally did functional several years before the surgeries. Then, in 2012, I found out I had sevetre spinal scoliosis. Just recently, I connected what I believe the reason for all of this degeneration. Oh, I forgot. Last August I was hospitalized with DVT of the Lt leg. I believe that the morphine is the cause. Your thougjts and any research on this you could refer me to. Thankyou, Cami Le
