Scientific Spine's Comment
Macnab criteria reflects well a surgeon's impression about the surgery's overall success in terms of patient's satisfaction, and how that particular patient should be categorized. Its roughness (only 4 class, and no detailed metrics of symptomatology) necessiates its use should be accompanied and backed by other scales such as pain scales and ODI, etc. It is still useful. However, its use as a sole outcome instrument is not acceptable in today's standards.
