Excerpt
We thank Prof. Shantanna for his notes. The aim of the study was to assess whether the effect of steroids injection into the site of the pain would be different from that of systemic corticosteroid use.
The intramuscular drug, triamcinolone acetonide, even in the paraspinal muscles, has systemic absorption and distribution. It differs from triamcinolone hexacetonide, which has potent local action, promoting chemical synovectomy of the joints.1 However, after a longer period, triamcinolone hexacetonide has also systemic distribution. Thus, the main difference between the 2 drugs is the local action of triamcinolone hexacetonide that was used in the experimental group.
Sample size calculation and statistical errors were described, although a larger number of subjects could demonstrate more differences between groups for different parameters.
Finally, we were concerned about our major difficulty that lies in the diagnosis. Does facet syndrome actually denounce patients with pain of facet origin?2,3
We appreciate the concerns and suggest further studies.
