Background. Radiofrequency ablation (RFA) is a less invasive technique for treatment of sacroiliac joint (SIJ) pain. Objective. To evaluate the feasibility and efficacy of endoscope-guided RFA for the treatment of CLBP from the SIJ complex. Methods. In this retrospective study, the medical records of 17 patients who underwent endoscope-guided RFA of the SIJ complex were reviewed. A bipolar radi...

We consider a closed manifold M with a Riemannian metric gij(t) evolving by ∂t gij = −2Sij where Sij(t) is a symmetric two-tensor on (M, g(t)). We prove that if Sij satisfies the tensor inequality D(Sij , X) ≥ 0 for all vector fields X on M , where D(Sij , X) is defined in (1.6), then one can construct a forwards and a backwards reduced volume quantity, the former being non-increasing, the latt...

BACKGROUND To estimate and compare the sacroiliac joint (SIJ) index in skeletal scintigraphy by four different methods of quantification employed in normal subjects of different age groups. MATERIAL AND METHODS The whole-body skeletal survey of 100 subjects, who underwent skeletal scintigraphy three hours after injection of 99mTc-Methylene Diphosphonate (MDP), were selected for this analysis....

BACKGROUND The sacroiliac joint (SIJ) is a major source of pain in patients with chronic low back pain. Radiofrequency ablation (RFA) of the lateral branches of the dorsal sacral rami that supply the joint is a treatment option gaining considerable attention. However, the position of the lateral branches (commonly targeted with RFA) is variable and the segmental innervation to the SIJ is not we...

New complexity results are derived. It is shown that the two machine flow shop problem with a single server is NP-hard if either the setup times or the processing times are constant. Furthermore, polynomial algorithms are given for special cases in which both setup times and processing times are constant. Flow-shop problems with a single server are generalizations of classical flow-shop problem...

INTRODUCTION The rate of fusion surgery of the lumbar spine has remarkably increased over the past 30 years. SOURCES OF DATA We performed a comprehensive search of studies addressing the assessment of sacroiliac joint (SIJ) after lumbar spinal fusion surgery on PubMed, OVID/Medline, Cochrane, CINAHL, Google scholar and Embase. AREAS OF AGREEMENT The fusion of spinal segments leads to degene...

Arthrodesis of the sacroiliac joint (SIJ) for surgical treatment of SIJ dysfunction has regained interest among spine specialists. Current techniques described in the literature most often utilize intraoperative fluoroscopy to aid in implant placement; however, image guidance for SIJ fusion may allow for minimally invasive percutaneous instrumentation with more precise implant placement. In the...

We describe a case report and technique for using a portable ultrasound scanner and a curvilinear transducer (4-5MHz) (SonoSite Micromaxx SonoSite, Inc. 21919 30th Drive SE Bothwell W. A.) to guide sacroiliac joint (SIJ) injection. A 42-year-old male presented with chronic lower back pain centered on his left SIJ. His pain averaged 7 out of 10 (numerical rating scale). For the ultrasound-guided...
