Hello , this appears to be a a case of spondylisthesis secondary to spondylolysis (pars defect) on x ray and MRI wee need to see your degree of slip and your neuro examination and depending upon that we need to decide surgery. Usually in cases secondary to pars defect back pain is more and this require fusion surgeries. But you need to be in guard in future even if you do the surgery.

Surgery depends on your problem and not Mri. So clinically needs evaluation Kindly check with doctor. Thanks

Yes.
