This is the North American Spine Society’s evidence-based clinical guideline on diagnosing and treating lumbar disc herniation with radiculopathy, nerve-related leg pain caused by a slipped disc. It covers examination, imaging, and treatment options.
What was studied?
The guideline assessed the evidence behind diagnostic tests, including muscle strength testing, sensory testing and the straight leg raise, alongside imaging choices and treatment pathways from structured exercise to surgical referral.
What did they find?
Physical examination tests earned the guideline's strongest Grade A recommendation for diagnosis, with MRI as the main confirming scan. Structured exercise is favoured for mild-to-moderate symptoms, and surgery is considered within 6 months for severe cases.
Why it matters
This framework shows when a nerve-related back problem needs urgent escalation and when it is reasonable to start with conservative, hands-on care. Many disc herniations improve or shrink on their own.
Why we included it
It shows how a structured, graded evidence framework can determine the right order of treatment steps, escalating only when the evidence justifies it rather than defaulting to the most invasive option.
