Abstract
BACKGROUND
While pain in the severe sacroiliac joint (SIJ) is a common cause of lower back pain, SIJ disease is often overlooked as a diagnosis.
OBJECTIVE
This study examines the extent of sufficient long-term pain relief and functional improvement in patients with SIJ syndrome that are treated with thermocoagulation. Some patients treated with thermocoagulation noted initial improvement, but the functionality and pain relief had limited duration and efficacy. Patients with insufficient improvement were recommended to undergo fusion surgery as an option for better and longer lasting results.
METHOD
Patients with a long history of back or pelvic problems were selected for the study. Endoscopic thermal coagulation of the SIJ was carried out. The follow-up examinations took place after 1, 3, 6, 12 months. In patients with insufficient pain relief and functionality after thermocoagulation, a fusion surgery was performed. The results of the fusion surgery were documented over a 12-month follow-up period. To carry out the statistical evaluation visual analog scale (VAS), Oswestry-Disability-Index (ODI) and the consumption of opioids were recorded.
RESULTS
Forty-eight patients were included. The mean VAS values 12 months after thermocoagulation were 68.9. The ODI after 12 months was very near or somewhat higher than their baseline prior to the thermocoagulation. Thus, a fusion surgery was recommended. Thirty-three patients agreed to the fusion operation. The VAS values 12 months after fusion surgery decreased to 53.1. Analogous to the VAS values, the Oswestry index (ODI) showed a significant improvement after the fusion operation.
CONCLUSION
The success of surgical intervention in 88% of the SIJ syndrome patients with inadequate results 12 months after thermocoagulation proves the superiority of SIJ fusion surgery. This study showed long-lasting pain relief by an average of 65% and a median improvement in functional impairments of 60%. In view of these results, fusion surgery should be considered for patients without sufficient success of thermocoagulation.
