Low back pain is considered chronic after 3 months because most normal connective tissues heal within 6-12 weeks, unless pathoanatomic instability persists. A slower rate of tissue repair in the relatively avascular intervertebral disk may impair the resolution of some persistent painful cases of chronic low back pain. An estimated 15%-20% develop protracted pain, and approximately 2%-8% have chronic pain. Of those individuals who remain disabled for more than 6 months, fewer than half return to work, and after 2 years of low back pain disability, a return to work is even more unlikely.
