The purpose of this retrospective study was to evaluate the clinical and radiological outcome of bilateral sacroiliac joint (SIJ) fusion, using a new technique, in patients with a chronic SIJ syndrome. Seventeen patients with chronic low back pain, with a positive response to specific diagnostic tests for the SIJ, were considered candidates for bilateral sacroiliac fusion. The surgical indicati...

Sacroiliac joint (SIJ) pathology is a common etiologic cause for 10 - 27% of cases of mechanical low back pain (LBP) below the L5 level. In the absence of definite clinical or radiologic diagnostic criteria, controlled blocks of the SIJ have become the choice assessment method for making the diagnosis of SIJ pain. The SI joint is most often characterized as a large, auricular-shaped, diarthrodi...

STUDY DESIGN A pooled patient-level analysis of two multicenter randomized controlled trials and one multicenter single-arm prospective trial. OBJECTIVE The aim of this study was to identify predictors of outcome of conservative and minimally invasive surgical management of pain originating from the sacroiliac joint (SIJ). SUMMARY OF BACKGROUND DATA Three recently published prospective tria...

OBJECTIVE The objective of this study was to evaluate the reliability of recognising structural lesions on MRI (erosions, fatty lesions, ankylosis) of the sacroiliac joints (MRI-SIJ) in clinical practice compared to a central reading in patients with a possible recent axial spondyloarthritis (axSpA). METHODS Patients aged 18-50 years, with recent (<3 years) and chronic (≥3 months) inflammator...

BACKGROUND This study compares the frequency and distribution of increased activity on 18 F-fluoride PET/CT with the presence of bone marrow edema on whole-body MR imaging in the spine and sacroiliac joints (SIJ) of patients with active ankylosing spondylitis (AS). METHODS Ten patients (6 men and 4 women), between 30 and 58 years old (median 44) with active AS, were prospectively examined wit...

The lexicographic kernel of a game lexicographically maximizes the surplusses sij (rather than the excesses as would the nucleolus). We show that an element in the lexicographic kernel can be computed efficiently, provided we can efficiently compute the surplusses sij(x) corresponding to a given allocation x. This approach improves the results in [2] and allows us to determine a kernel element ...

Let k, l,m, n, and μ be positive integers. A Zμ-scheme of valency (k, l) and order (m,n) is an m × n array (Sij) of subsets Sij ⊆ Zμ such that for each row and column one has ∑n j=1 |Sij | = k and ∑m i=1 |Sij | = l, respectively. Any such scheme is an algebraic equivalent of a (k, l)-semiregular bipartite voltage graph with n and m vertices in the bipartition sets and voltages coming from the c...

BACKGROUND The aim of this study was to investigate subgroups of magnetic resonance imaging (MRI) findings for the spine and sacroiliac joints (SIJs) using latent class analysis (LCA), and to investigate whether these subgroups differ in their demographic and clinical characteristics. METHODS The sample included 1037 patients aged 18-40 years with persistent low back pain (LBP). LCA was appli...
