62 y/o female w/ spinal stenosis, scoleosis, herniated discs & arthritis, mri done told spine was narrowing? suggested surg w/ cage around spine?

Potentially: Spinal stenosis is a condition in which the canal that transmits the spinal nerves is narrowed, often by bone spurs and disc protrusions. Surgical options include removing the structures pushing on the nerves, known as a decpressiin; or doing a decompression and then fusing the bones together. When you mentioned a cage, that suggests your surgeon recommended a fusion.
