BACKGROUND Previous studies have revealed that ankylosing spondylitis (AS), as the progenitor of axial spondyloarthritis (AxSpA), has been characterized by the insidiously progressive nature of sacroiliitis and spondylitis. Dual-energy computed tomography (DECT) has recently been used to analyse the deposition of monosodium urate (MSU) crystals with higher sensitivity and specificity. However, ...

PURPOSE To study the course of L4 to S3 nerve roots and their distance with the ala of the sacrum and the sacroiliac joint. METHODS The embalmed left half pelvis of 25 male and 27 female cadavers aged 30 to 91 (mean, 68) years were studied. The ventral rami of the L4, L5, S1, S2, and S3 nerve roots were dissected along their courses from the corresponding intervertebral foramina to the lesser...

Background: Previous studies have revealed that ankylosing spondylitis (AS), as the progenitor of axial spondyloarthritis (AxSpA), has been characterized by the insidiously progressive nature of sacroiliitis and spondylitis. Dual-energy computed tomography (DECT) has recently been used to analyse the deposition of monosodium urate (MSU) crystals with higher sensitivity and specificity. However,...

Psoriatic arthritis (PsA) is a chronic inflammatory disease characterized by the coexistence of arthritis with psoriasis of the skin and nails. The sacroiliac joints were observed in 34-78% of patients with psoriatic arthritis. Due to such a high prevalence of SIJ dysfunction, understanding pathophysiology of pain and the associated pain pattern becomes a very important aspect of PsA diagnosis....

The crescent fracture consists of a posterior iliac wing fracture with extension into the sacroiliac joint and a dislocation of the sacroiliac joint. This fracture represents a subset of lateral compression injury. The strong posterior ligaments of sacroiliac joint remain intact and a fracture fragment (crescent shape) involving the posterior superior iliac spines remains firmly attached to the...

background chronic sacroiliac (si) joint pain constitutes 16% to 30% of the total prevalence of chronic low back pain, which is commonly unilateral. apart from conservative management, various interventional pain management procedures have been reported. intraarticular deposteroid injection has been described as the most evidence-based, but different various radio frequency (rf) procedures have...

Patients 405 women at 33 weeks of gestation were classified into 5 subgroups on the basis of their history and objective pelvic joint pain (> 1 positive test from a joint): the pelvic girdle syndrome (n=118; daily pain in all 3 pelvic joints); symphysiolysis (n=38; daily pain in pubic symphysis only); the 1-sided sacroiliac syndrome (n=98; daily pain from 1 sacroiliac joint alone); the doublesi...

       Fractures through the sacroiliac joint are very challenging to treat, technically difficult to reduce through closed methods on account of the multiaxial displacement of fractures fragments, frequently occur in very unwell patients, and have poor outcomes if malreduction is present. We describe a technique utilising the lateral window and a short buttress plate to reduce and stabilize th...

We present the case of 56-year-old man who came to the emergency department with a 48-h history of fever and pain in left gluteus, radiating to posterior thigh. Three days before the onset of the symptoms, the patient had self-administered a dose of intraurethral alprostadil to treat erectile dysfunction secondary to prostatectomy for adenocarcinoma of the prostate. Physical examination reveale...
