Doc advises l4-l5 fusion ...but other options?
I'm 70 F, very lucky to have been an active and healthy, pain-free person all my life. About a year ago pain started in my right lower back with intermittent radiation down my leg (tingling and numbness no pain below the lower back). I've now had an MRI and EMG and the last step is an extension/flexion x-ray which I'm getting today (to determine if the area, which includes a slipped disc, is unstable). Severe stenosis at L4 L5 is the diagnosis. The pain is manageable during the day but it keeps me up at night--I wake up every single time I turn in bed. I remain active and am in good physical condition.
The spine surgeon is a highly regarded MD with a great success rate. At my appointment yesterday, he said the likely best and "most durable" option for me is fusion, based on my symptoms and in his opinion probable instability in the area which would rule out less invasive options.
But is it? Is a minimally invasive procedure such as decompression or endoscopic surgery really not possible if there is "instability" in the area?
After reading about the length of recovery and rehab from a fusion surgery I am very reluctant to get such invasive, serious surgery.
I'd be grateful for any opinions on this from the community!
