OBJECT The sacroiliac joint (SIJ) and surgical intervention for treating SIJ pain or dysfunction has been a topic of much debate in recent years. There has been a resurgence in the implication of this joint as the pain generator for many patients experiencing low-back pain, and new surgical methods are gaining popularity within both the orthopedic and neurosurgical fields. There is no universal...

There are currently no initial guides for the diagnosis of somatic referred pain of lumbar zygapophyseal joint (LZJ) or sacroiliac joint (SIJ). We developed a classification system of LZJ and SIJ pain, the ''pain distribution pattern template (PDPT)'' depending on the pain distribution patterns from a pool of 200 patients whose spinal pain source was confirmed. We prospectively applied the PDPT...

Background Sacroiliac joint (SIJ) degeneration is a common source of low back pain (LBP). Minimally invasive (MI) SIJ fusion procedures have demonstrated meaningful clinical improvement. A recently developed MI SIJ fusion system incorporates decortication, placement of bone graft and fixation with threaded implants (DC/BG/TF). Patients and Methods Nineteen patients who had MI SIJ fusion with ...

We present a new set of 3.5 Post-Newtonian equations in which Newtonian hydrodynamics is coupled to the nonconservative effects of gravitational radiation emission. Our formalism differs in two significant ways from a similar 3.5 Post-Newtonian approach proposed by Blanchet (1993, 1997). Firstly we concentrate only on the radiation-reaction effects produced by a time-varying mass-current quadru...

[Purpose] Physical therapists, osteopathic practitioners, and chiropractors often perform manual tests to evaluate sacroiliac joint (SIJ) mobility. However, the available evidence demonstrates an absence of reliability in these tests and in investigations with kinematic analysis. The aim of this study was to verify the three-dimensional kinematic reliability in SIJ movement measurements. [Subje...

There are many tests devised to provide information about sacroiliac joint (SIJ) pain and function. Only pain provocation SIJ tests have been shown to have satisfactory inter-examiner reliability and validity with respect to a meaningful reference standard. These tests apply stress to the SIJ to determine if the usual pain is produced or aggravated and have been described in the orthopaedic med...

Sacroiliac joint (SIJ) is an uncommon localisation of osteoarthritis. Instability of this joint is one of rare aetiologies. It can occur after resection of the pubic symphysis for whatever the reason. The biomechanical consequences on the SIJ are increasing shear forces and vertical restrain. This leads to secondary progressive SIJ osteoarthritis. There is no specific rehabilitation programme f...
