Dr. Patel discusses the use of lateral branch neurotomy for sacroiliac joint pain improves pain and physical function
51 patients experiencing sacroiliac joint (SIJ) pain were randomized on a 2:1 basis into two groups to either receive lateral branch radiofrequency (RF) neurotomy or a sham treatment. Following assessments over a 9 month period, results indicated that patients who underwent lateral branch RF neurotomy treatment noticed a significant decrease in pain, disability, and an increase in physical function.
Was the allocation sequence adequately generated?
Was allocation adequately concealed?
Blinding Treatment Providers: Was knowledge of the allocated interventions adequately prevented?
Blinding Outcome Assessors: Was knowledge of the allocated interventions adequately prevented?
Blinding Patients: Was knowledge of the allocated interventions adequately prevented?
Was loss to follow-up (missing outcome data) infrequent?
Are reports of the study free of suggestion of selective outcome reporting?
Were outcomes objective, patient-important and assessed in a manner to limit bias (ie. duplicate assessors, Independent assessors)?
Was the sample size sufficiently large to assure a balance of prognosis and sufficiently large number of outcome events?
Was investigator expertise/experience with both treatment and control techniques likely the same (ie.were criteria for surgeon participation/expertise provided)?

O Índice de Fragilidade é uma ferramenta que auxilia na interpretação de achados significativos, fornecendo uma medida de força para um resultado. O Índice de Fragilidade representa o número de eventos consecutivos que precisam de ser adicionados a um resultado dicotómico para que o resultado deixe de ser significativo. Um número pequeno representa um resultado mais fraco e um número grande representa um resultado mais forte.
Porque é que este estudo era necessário agora?
Sacroiliac joint (SIJ) pain is a common form of lower back pain. Intra-articular SIJ injections are normally used to treat the condition, but sometimes this method is ineffective or only provides short-term pain relief. Lateral branch RF neurotomy has been suggested as an alternative treatment for SIJ pain, but few studies have assessed the efficacy of this method. This study aimed to determine the effectiveness of lateral branch RF neurotomy in pain management of SIJ pain.
Qual era a principal questão de investigação?
Did lateral branch radiofrequency neurotomy significantly decrease sacroiliac joint pain and increase physical function, when measured over a 9 month period?
- The mean improvement in NRS pain score at the 3 month assessment was significantly higher in the Lateral Branch Neurotomy group (-2.4 +/- 2.7) than in the Sham group (-0.8 +/- 2.4) (p=0.035)
- The mean improvements in SF-36 for bodily pain at the 1 and 3 month assessments were significantly higher in the Lateral Branch Neurotomy group (Month 1: 15 +/- 17, Month 3: 16 +/- 26) than in the Sham group (Month 1: 2 +/- 11, Month 3: -1 +/- 13) (Month 1: p=0.006, Month 3: p=0.019)
- The mean improvements in SF-36 for physical function at the 1 and 3 month assessments were significantly higher in the Lateral Branch Neurotomy group (Month 1: 10 +/- 17, Month 3: 14 +/- 19) than in the Sham group (Month 1: 5 +/- 12, Month 3: 3 +/- 12) (Month 1: p=0.238, Month 3: p=0.040)
- The mean improvements in ODI at the 1 and 3 month assessments were significantly higher in the Lateral Branch Neurotomy group (Month 1: -12 +/- 14, Month 3: -11 +/- 17) than in the Sham group (Month 1: -4 +/- 11, Month 3: 2 +/- 6) (Month 1: p=0.046, Month 3: p=0.011)
- The percentage of patients who had a positive GPE score (positive defined as “pain has decreased a lot”) at the 3 month assessment was significantly higher in the Lateral Branch Neurotomy group (47%) than in the Sham group (8%) (p<0.05)
- The mean AQoL score at the 3 month assessment was significantly higher in the Lateral Branch Neurotomy group (0.69 +/- 0.21) than in the Sham group (0.56 +/- 0.21) (p=0.048)
De que é que me devo lembrar mais?
Patients who underwent lateral branch RF neurotomy experienced significant improvements in SIJ pain, disability, physical function, and quality of living compared to those who underwent the sham treatment.
Como é que isto afectará o tratamento dos meus doentes?
Patients who have failed to get pain alleviation after taking intra-articular SIJ injections are may benefit from lateral branch RF neurotomy. Further research with larger sample sizes and longer follow-up are required to confirm the benefits.
