Does instrumented fusion improve pain and disability in patients with chronic low back pain compared to preoperative patients?
Instrumented fusion for chronic low back pain is associated with significantly lower pain and disability compared to preoperative status, though severe disability persists in a small subset of patients.
Bentsen et al. (2009) studied this question.
