i don't really have enough patient-specific information to give that "okay" so you will need to call the neurosurgeon who is treating his scoliosis for that answer. thirty degrees is a significant curve in a growing boy but i don't know where this curve is located on his back (thoracic lumbar) and if he is lifting weights properly.
my 15 yr. old son has scoliosis. his curve is about 30 degrees. is it safe for him to lift weights?
