The clinical efficacy was evaluated by the standard Macnab’s evaluation [1 (link)] and visual analog scale (VAS) scores. The pain intensity is evaluated by VAS (0–10; 0 represent no pain; 10 represents the worst pain). Improvement in Macnab’s evaluation standard was divided into four grade. Excellent: No pain, no restriction of mobility, return to normal work and level of activity. Good: Occasional non-radicular pain, relief of presenting symptoms, able to return to modified work. Fair: Some improved functional capacity, still handicapped and/or employed. Poor: Continued objective symptoms of root involvement, additional operative invention needed at index level irrespective of length of postoperative follow-up. Postoperation CT (Toshiba Aquilion, Japan) and MRI (GE HDxt-3T, GE, American) of vertebrae was examined.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
