UNASSIGNED: The most effective injective treatment approach for sacroiliac joint (SIJ) pain remains unclear. Aim of this study was to quantify the safety and effectiveness of the available injective strategies to address SIJ pain.
UNASSIGNED: A systematic review and meta-analysis of the literature was conducted on PubMed, Scopus, and Embase databases from inception until January 2023. Inclusion criteria were studies written in English, comparative and non-comparative studies regardless of the minimum follow-up, and case series on SIJ injections. Safety and efficacy of the different injection therapies for the SIJ were quantified. A meta-analysis was conducted on the available data of the documented injective therapies. The \"Checklist for Measuring Quality\" by Downs and Black was used to assess the risk of bias and the quality of papers.
UNASSIGNED: The literature search retrieved 43 papers (2431 patients): 16 retrospective case series, 2 retrospective comparative studies, 17 prospective case series, 3 prospective comparative studies, and 5 randomized controlled trials. Of the selected studies, 63% examined the effect of steroid injections, 16% of PRP injections, while 21% reported other heterogeneous treatments. The failure rate was 26% in steroid injections and 14% in PRP injections. The meta-analysis showed a statistically significant reduction in pain with the VAS score for both steroids and PRP: steroids improvement at mid-term 3.4 points (p < 0.05), at long-term 3.0 (p < 0.05), PRP improvement at mid-term 2.2 (p = 0.007), at long-term 2.3 points of the VAS pain scale (p = 0.02).
UNASSIGNED: Steroids are the most documented injective approach, with studies showing an overall safety and effectiveness. Still, the high number of failures underlined by some studies suggest the need for alternative procedures. Early PRP data showed promise, but the limitations of the current literature do not allow to clearly define the most suitable injective approach, and further studies are needed to identify the best injective treatment for SIJ patients.

Sacroiliitis is the inflammation of the sacroiliac joint, the largest axial joint in the human body, contributing to 25% of lower back pain cases. It can be detected using various imaging techniques like radiography, MRI, and CT scans. Treatments range from conservative methods to invasive procedures. Recent advancements in artificial intelligence offer precise detection of this condition through imaging. Treatment options range from physical therapy and medications to invasive methods like joint injections and surgery. Future management looks promising with advanced imaging, regenerative medicine, and biologic therapies, especially for conditions like ankylosing spondylitis. We conducted a review on sacroiliitis using imaging data from sources like PubMed and Scopus. Only English studies focusing on sacroiliitis\'s radiological aspects were included. The findings were organized and presented narratively.

Sacroiliac joint (SIJ) pain is a common cause of low back pain. Traditionally, treatment for SIJ joint pain and dysfunction has consisted of physical therapy, medication management, SIJ injections, and SIJ ablations. Improved recognition of the SIJ as an etiology for back pain has led to advances in treatment options. Radiofrequency of the lateral sacral branches has been shown to be effective, though evidence is fraught with inconsistent patient selection, study design and procedural technique. It also does not directly address the mechanical dysfunction of the SIJ. In order to create a more enduring approach SIJ fusion has become an attractive option to reduce pain and to improve function. This method of SI joint treatment requires guidance in the perioperative phase of care from both the physicians and advanced practice providers (APP). In order to improve care and outcomes of those undergoing posterior SI joint fusion the American Society of Pain and Neuroscience appointed an expert panel of physicians and advanced practice providers to create a best practice for the post operative care of this approach. As with any best practice, the panel considered current peer reviewed literature and clinical expertise to create guidance today. This is intended to be a living document with modifications as additional evidence comes to light in data publication. The goals of this paper are to focus on (1) wound care, (2) medication use, (3) physical activity and (4) therapeutic exercises.

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.
METHODS: 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.
CONCLUSIONS: 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.

OBJECTIVE: Two main surgical approaches are available for fusing the sacroiliac joint (SIJ): an open or minimally invasive (MIS) approach. The purpose of this study was to analyze the associated total hospital charges and postoperative complications of the MIS and open approach.
METHODS: Using the 2016 and 2017 National Readmission Database, we conducted a retrospective cohort analysis of 2521 patients who received a SIJ fusion with an open (N = 1990) or MIS (N = 531) approach for diagnosed sacrum pain, sacroiliitis, sacral instability, or spondylosis. Each cohort was analyzed for postoperative complications.
RESULTS: We identified 604 patients diagnosed with sacrum pain, 1142 with sacroiliitis, 315 with spondylosis, and 288 with sacral instability. Patients who received the open approach for sacrum pain had significantly higher rates of novel post-procedural pain (p = 0.045) and novel lumbar pathology (p = 0.015) within 30 days. On 30-day follow-up, patients with sacroiliitis treated with open SIJ fusion had significantly higher rates of novel postprocedural pain compared to those treated with MIS fusion (p = 0.045). Patients who received the open approach for spondylosis resulted in significantly higher rates of non-elective readmission within 30 days compared to the MIS approach (p < 0.0001). In addition, the open technique for spondylosis resulted in significantly higher rates of non-elective readmissions for infection within 30 days (p = 0.014). On 30-day follow-up, patients with sacral instability treated with open SIJ fusion had significantly higher rates of UTI (p = 0.045).
CONCLUSIONS: Our study suggests that there exist unique postoperative complications that arise after SIJ fusion specific to preoperative diagnosis and surgical approach.

UNASSIGNED: Sacroiliac joint (SIJ) pain is one of the most common causes of low back pain, accounting for 15 to 30% of all cases. Although SIJ dysfunction accounts for a large portion of chronic low back pain prevalence, it is often overlooked or under diagnosed and subsequently under treated. The purpose of this review was to establish a best practices model to effectively diagnose SIJ pain through detailed history, physical exam, review of imaging, and diagnostic block.
UNASSIGNED: A literature search was performed on the diagnosis of sacroiliac joint pain and sacroiliac joint dysfunction. The authors proposed diagnostic recommendations based upon the available literature and a detailed understanding of diagnosing SIJ pain.
UNASSIGNED: The practitioner must focus on the history, location of pain, observed gait pattern, and perform key points of the physical exam including sacroiliac provocative maneuvers. If the patient exhibits at least three provocative maneuvers then the SIJ may be considered as a possible source of pain. Additionally, a thorough review of the imaging should be performed to rule out other etiologies of low back pain. In the absence of any pathognomonic tests or examination findings, diagnostic SIJ blocks have evolved as the diagnostic standard.
UNASSIGNED: The diagnosis of SIJ pain is a multifaceted process that involves a careful assessment including differentiating other pain generators in the region. This involves careful history taking, appropriate physical examination including provocative maneuvers and diagnostic injections. Once the diagnosis is confirmed, long-term solutions may be considered, including recent advances in sacral lateral branch denervation and sacroiliac joint fusion.

This study reports the reliability of the juvenile idiopathic arthritis magnetic resonance imaging scoring system (JAMRIS-SIJ). The study comprised of eight raters-two rheumatologists and six radiologists-and 30 coronal T1 and Short-Tau Inversion Recovery (STIR) MRI scans of patients with enthesitis-related juvenile spondylarthritis. The median age of patients was 15 years with a mean disease duration of 5 years and 22 (73.3%) of the sample were boys. The inter-rater agreement of scores for each of the JAMRIS-SIJ items was calculated using a two-way random effect, absolute agreement, and single rater intraclass correlation coefficient (ICC 2.1). The ICC was interpreted together with kurtosis, since the ICC is also affected by the distribution of scores in the sample. The eight-rater, single measure inter-rater ICC (and kurtosis) values for JAMRIS-SIJ inflammation and damage components were the following: bone marrow edema (BME), 0.76 (1.2); joint space inflammation, 0.60 (1.8); capsulitis, 0.58 (9.2); enthesitis, 0.20 (0.1); ankylosis, 0.89 (35); sclerosis, 0.53 (4.6); erosion, 0.50 (6.5); fat lesion, 0.40 (21); backfill, 0.38 (38). The inter-rater reliability for BME and ankylosis scores was good and met the a priori set ICC threshold, whereas for the other items it was variable and below the selected threshold. Future directives should focus on refinement of the scores, definitions, and methods of interpretation prior to validation of the JAMRIS-SIJ through the assessment of its measurement properties.

METHODS: A retrospective case-series of revision sacroiliac joint (SIJ) fusions.
OBJECTIVE: To provide a technique guide for revision minimally invasive SIJ fusion.
BACKGROUND: SIJ dysfunction is a prevalent, yet underdiagnosed condition. This disparity exists as a result of diagnostic complexity and lack of a viable surgical treatment option. However, the advent of minimally invasive SIJ fusion has created a resurgence of interest in this debilitating condition. Multiple studies have reported on the increased use of minimally invasive SIJ fusion in recent years, but there is a paucity of literature on management in a revision setting.
METHODS: A case series of 5 patients from a single academic tertiary referral center over a 3-year period will serve to highlight technical pearls and considerations in SIJ fusion revision. Revision SIJ fusions were identified through a retrospective review of a surgical database and demographic, surgical, and radiographic data were obtained through review of the electronic medical record.
RESULTS: Five patients underwent SIJ fusion revision from 2015 to 2018. There were 3 main modes of failure, with indications for revision including nerve root irritation and SIJ pain recurrence. The mean age at time of revision was 48.8 ± 14.3 years, and the mean follow-up after revision was 2.0 + 0.9 years. Familiarity with SIJ anatomy and use of stereotactic navigation can improve implant position and purchase. Additionally, bone graft and bone morphogenetic protein can be used to fill in old implant tracks and to augment bony ingrowth and ongrowth of new implants.
CONCLUSIONS: Increased use of SIJ fusion creates a demand for comprehensive revision strategies and necessitates familiarity with SIJ anatomy. Preoperative planning to determine causes of failure and use of intraoperative navigation are essential to help surgeons better understand the preferential trajectory for each implant.
METHODS: 4.

UNASSIGNED: Selective nerve root block (SNRB) is a procedure that can be used as a diagnostic or a therapeutic method. SNRB can be used in multiple sites, including cervical and lumbar . Our study aims to investigate the clinical effectiveness of the use of fluoroscopically guided therapeutic selective nerve root block as a non-surgical symptom management of lumbar radiculopathy.
UNASSIGNED: This is a prospective study of therapeutic nerve root block in 76 patients with low back pain and/or sciatica at Jordan University Hospital. Data was collected by independent clinical interviewers, and visual analogue score (VAS) was used to measure pain severity.
UNASSIGNED: A total of 76 patients, 25 (32.8%) males and 51 (67.2%) females, underwent SNRB. 69 (90.7%) patients improved immediately after the procedure. Out of the total, 22 (28.9%) patients showed a long-term relief of symptoms and did not experience any recurrence during the three months of follow-up, while 47 (61.8%) experienced a recurrence of pain. In patients experiencing recurrence of symptoms, 35 needed surgery.
UNASSIGNED: Therapeutic SNRB is an important procedure in the pain management of patients with lumbar radiculopathy caused by lumbar disc prolapse and foraminal stenosis. Our study showed that avoidance of surgery was achieved in up to 54% of patients; pain relief for at least 6 months was achieved in up to 29% of patients after a single SNRB. This makes it a very good second line of management after conservative treatment and a possible method to delay, and sometimes cease, the need for surgery.

The sacroiliac joint (SIJ) is an important contributor to persistent and functionally limiting lower back pain. Despite extensive debate and research, there is no definitive treatment recommendation or high-level evidence to support a conservative care treatment approach, nor interventional or surgical management procedures for the alleviation of pain originating from the SIJ. Traditional physical therapy and conservative approaches to generalized lower back pain often fail in this patient subset prompting sub-specialty consultation to a pain management center. Diagnosis of the SIJ as the pain generator can be accomplished through physical exam maneuvers and comparative diagnostic blocks; however, upon diagnosis, management remains a challenge. After the diagnosis of SIJ dysfunction is made in our young and active patient population, we have seen significant success in the application of an interdisciplinary and evidence-based treatment algorithm similar to the presented case. To our knowledge, this treatment approach has not been previously described.
