I have bilateral degenerative changes at l5-s1 level w/a grade 1-2 spondylolisthesis found 9/2012 has become worse will i end up needing surgery?

Probably: If you are getting worse, i would suggest a follow-up MRI and a consultation with a spine surgeon. Conservative care certainly helps some patients. However, if you are getting worse, surgery may ultimately be required. Check out spinehealth.Com.

Spine Surgery: Spine surgery is reserved for individuals that have unrelenting pain that has failed conservative care or who have a progressive neurologic condition due to the spinal changes. Many individuals with your radiographic finding are pain free. If worsening would followup with your doctor or see a surgical or nonsurgical spine specialist.

Hopefully not: If you take good care of your back, strengthen your core and do exercises. No one has a crystal ball.
