Decompression only versus decompression plus fusion for spinal canal stenosis of adjacent segment during primary single-segment lumbar fusion surgery

Patients with lumbar spinal canal stenosis without foraminal stenosis in the adjacent segment show no significant difference with adjacent segment decompression versus additional fusion when undergoing a primary single-level fusion. Decompression only of the adjacent segment could potentially be favored to opt for a slightly better short-term clinical outcome after 3 months.
