METHODS An experimentally validated finite element model of the lumbar spine and pelvis was used to simulate a fusion of the SI joint using various placement configurations of triangular implants(iF use Implant System~?). Placement configurations were varied by changing implant orientation, superior implant length, and number of implants. The range of motion of the SI joint was calculated using a constant moment of 10 N-m with a follower load of 400 N. The changes in motion were compared between the treatment groups to assess how the different variables affected the overall motion of the SI joint. RESULTS Transarticular placement of 3 implants with superior implants that end in the middle of the sacrum resulted in the greatest reduction in range of motion(flexion/extension = 73%, lateral bending = 42%, axial rotation = 72%). The range of motions of the SI joints were reduced with use of transarticular orientation(9%-18%) when compared with an inline orientation. The use of a superior implant that ended mid-sacrum resulted in median reductions of(8%-14%) when compared with a superior implant that ended in the middle of the ala. Reducing the number of implants, resulted in increased SI joint range of motions for the 1 and 2 implant models of 29%-133% and 2%-39%, respectively,when compared with the 3 implant model.CONCLUSION Using a validated finite element model we demonstrated that placement of 3 implants across the SI joint using a transarticular orientation with superior implant reaching the sacral midline resulted in the most stable construct. Additional clinical studies may be required to confirm these results.展开更多

While radiofrequency neurotomy (RFN) is the interventional treatment of choice for spinal pain originating from the facet joints, fewer studies have investigated its potential for treating SIJ pain, and its long-term efficacy is unknown. Objectives: To obtain a real-world view of RFN treatment outcomes for SIJ pain by conducting an observational study within a community pain practice, among a heterogeneous patient group receiving standard-of-care diagnostic workup and treatment. Study Design: A prospective, observational study, with data collection over five years, was conducted at the authors' private practice. Patients & Methods: A cohort of 215 patients underwent fluoroscopically guided SIJ RFN of the dorsal and lateral branches of S1-S3 and the descending branch of L5. All patients had previously had their diagnosis of SIJ pain confirmed by controlled comparative analgesic blocks of relevant nerves, and recorded pre-procedure pain levels on the 11-point Numerical Rating Scale (NRS). Outcome measures included pain, and a Likert scale to measure alterations to analgesic use, changes to paid employment status and patient satisfaction. Results: We demonstrate an average pain reduction of 2.3 ± 2.1 NRS points following RFN (baseline pain score of 6.9 ± 1.7 to a follow-up average of 4.6 ± 2.7 NRS points;p ≤ 0.01). At a mean follow-up period of 14.9 ± 10.9 months (range 6 - 49 months), an overall 42.2% of patients reduced their analgesic use. Of the patients for whom employment capacity was applicable (82 patients), 21 patients reported an improvement. Overall, 67% of patients were satisfied with their outcome of post-RFN treatment. No complications occurred. Limitations: This observational study had no independent control group and only included a single study site. Conclusions: RFN is a safe and effective treatment for pain confirmed to originate from the sacroiliac joint.展开更多

Given that the features of SIJ pain are non-specific and that this referred pain is similar to lumbar facet joint and lumbar disc pain, diagnostic local anesthetic injections (diagnostic blocks) into the SIJ are used to identify the source of pain. Despite wide use, little is known about the false positive rate of a single diagnostic sacroiliac (SI) block and the requirement for a control block. Objective: To determine whether a control SI block is necessary and to monitor the false positive rate for a single injection. Study Design: A prospective and observational study was conducted as part of a practice audit, with data collected over 3.5 years at the authors’ private practice. Patients & Methods: Under fluoroscopic guidance, 1408 consecutive patients presenting with prominent deep somatic pain over the SIJ region were sterilely injected with anesthetic into the SIJ and/or the deep interosseous ligament (DIL). Pain was measured on the 11-point Numerical Rating Scale (NRS) prior to injection and incrementally over the following 1- 2 weeks. Fully completed and unequivocal data sets were available for 1060 patients. Decreases in pain scores (of >80%) at >2 hours of post-injection were indicative of SIJ pain and recorded as a positive SIJ block. Results: Of 1060 patients receiving a first SIJ diagnostic block, 680 (64.1%) recorded a positive result. Subsequently, 271 positive patients and 22 who were negative for SIJ pain opted to receive a second control block. SIJ pain diagnosis was confirmed in 237/271 (87.5%) of those with an initial positive response, while 18/22 patients (81%) had their initial negative result confirmed. The false positive rate of a single block is therefore calculated at 12.5%, and on a contingency table analysis, a single anesthetic SIJ injection has diagnostic accuracy of 87.03%, with high sensitivity (98.3%), when compared with a second control diagnostic block. Limitations: All injections were performed at one clinical centre. A proportion (348/1408) of initial patients did not return fully completed pain records or had equivocal responses (≥80% pain relief, but transiently, for ≤30 min) and were excluded from further analysis. Conclusion: Given the observed high rates of accuracy in this study, it is reasonable to suggest the use of one diagnostic block as the criterion standard for assessing the SIJ as the source of a patient’s pain.展开更多

Methods： A total of 60eligible cases were randomly allocated into an observation group and a control group, 30 in each group. Cases in the observation group were treated with conventional tuina plus reduction manipulation of sacroiliac joint subluxation; whereas cases in the control group were treated with conventional tuina plus acupuncture. The clinical effects were observed after 10 times of treatment. In addition, the relapse rates were observed 2 months after treatment. Results： The total effective rate in the observation group was 80.0%, versus 50.0% in the control group, showing a statistically significant difference （P＆lt;0.05）. The relapse rate of lumbosacral pain in the observation group was 12.5%, versus 66.7% in the control group, showing a statistically significant difference （P＆lt;0.01）. The relapse rate of leg length discrepancy in the observation group was 16.7%, versus 80.0% in the control group, showing a statistically significant difference （P＆lt;0.01）. Conclusion： Tuina reduction manipulation can obtain substantial therapeutic effect for leg length discrepancy and lumbosacral pain due to sacroiliac joint subluxation, coupled with a low relapse rate.展开更多
