STUDY DESIGN A prospective cohort study. OBJECTIVE To determine the cause-effect relationship between fusion and sacroiliac joint (SIJ) degeneration after instrumented posterolateral lumbar or lumbosacral fusion. SUMMARY OF BACKGROUND DATA Adjacent segment degeneration following spinal fusion has attracted considerable attention. However, little attention has been paid to the SIJ, which is ...

Background: Sacroiliac joint (SIJ) pain presents as a deep and somatic pain, predominantly affecting the lower back and buttock and referring down the leg, sometimes as far as the foot. 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...

To determine the association between inflammatory and structural lesions on sacroiliac joint (SIJ) MRI and BMD and to identify risk factors for low BMD in patients with axial spondyloarthritis (axSpA). Seventy-six patients who fulfilled the ASAS axSpA criteria were enrolled. All underwent SIJ MRI and BMD measurement at the lumbar spine, femoral neck, and total hip. Inflammatory and structural l...

Low back pain (LBP) represents the second most common cause of visits to primary care physicians with the loss of productivity, income, and associated medical expenses resulting in a $60 billion expenditure in the USA on an annual basis [ 1 ]. The sacroiliac joint (SIJ) has been identifi ed as one of the causes of LBP 15–30 % of the time at the initial offi ce visit [ 1 ]. The SIJ is a true syn...

INTRODUCTION The sacroiliac joint (SIJ) is a common source of low back pain. However, clinical and functional signs and symptoms correlating with SIJ pain are widely unknown. Pelvic belts are routinely applied to treat SIJ pain but without sound evidence of their pain-relieving effects. This case-control study compares clinical and functional data of SIJ patients and healthy control subjects an...

BACKGROUND Sacroiliac joint (SIJ) dysfunction is a prevalent cause of chronic, unremitting lower back pain. OBJECTIVE To concurrently compare outcomes after surgical and nonsurgical treatment for chronic SIJ dysfunction. METHODS A total of 148 subjects with SIJ dysfunction were randomly assigned to minimally invasive SIJ fusion with triangular titanium implants (n = 102) or nonsurgical mana...

BACKGROUND Pain from the sacroiliac joint (SIJ) is an under-recognized cause of low back pain. The degree to which SIJ pain decreases quality of life has not been directly compared to other more familiar conditions of the lumbar spine. METHODS Multivariate regression analysis of individual patient data from two prospective multicenter clinical trials of SIJ fusion and three prospective multic...

BACKGROUND Increasing evidence supports minimally invasive sacroiliac joint (SIJ) fusion as a safe and effective treatment for SIJ dysfunction. Failure to include the SIJ in the diagnostic evaluation of low back pain could result in unnecessary health care expenses. DESIGN Decision analytic cost model. METHODS A decision analytic model calculating 2-year direct health care costs in patients...

BACKGROUND Back pain is a common problem and has been shown to affect approximately 85% of the adult population at any one time. The source of this pain can be difficult to identify and the sacroiliac joint (SIJ) has been proposed as a possible pain source. Its percentage contribution to lower back pain is controversial. Clinical provocative tests for SIJ pathology have been developed but these...

OBJECTIVE IA injections of SIJs with corticosteroids are often performed in patients suffering from low back pain due to active sacroiliitis. However, SIJ injections are technically demanding, and therefore the clinical outcome of ultrasound-guided corticosteroid SIJ injections was analysed in relation to the accuracy of the injection. METHODS Ultrasound-guided injections were performed with ...
