Background:
We hypothesized that ultrasound-guided selective nerve root block could play a role in the prediction of clinical outcomes in patients with multilevel cervical disease following selective anterior cervical discectomy and fusion.
Methods:
Patients were randomized to receive ultrasound-guided selected nerve root block as a diagnostic tool (study group) or not (control group), but both groups had surgery. Pain evaluation for arm and neck pain was recorded. The Visual Analog Scale (VAS) pain scores, Neck Disability Index, and MRI results were compared between groups. They were assessed every two weeks for three months, postoperatively. The percentage of patients who showed ≥ 50% reduction in their pain levels and a VAS rating of ≤2 was deemed an acceptable surgical outcome.
Results:
Patients in the study group had significantly lower VAS scores for pain intensity than control patients at nearly all periods. This baseline pain improved significantly in the study group. A more significant proportion of patients in the study group showed a ≥50% reduction in their pain scores from baseline at weeks four, eight, and 12, and this difference was significantly lower than in the control group (P<0.05). The study group improved significantly over baseline in Neck Disability Index scores compared to control patients. Patients were highly satisfied with no significant adverse events in the study group.
Conclusions:
In patients with multilevel cervical disease, ultrasound-guided selective nerve root block is an excellent, safe, non-radiating, and reliable test to determine the appropriate level for operation.
