Sources of Sacroiliac Region Pain: Insights Gained From a Study Comparing Standard Intra-Articular Injection With a Technique Combining Intra- and Peri-Articular Injection

摘要: Abstract Borowsky CD, Fagen G. Sources of sacroiliac region pain: insights gained from a study comparing standard intra-articular injection with technique combining intra- and peri-articular injection. Objectives To present evidence supporting the existence extra-articular sources for pain to that anesthetic blockade may underestimate true prevalence pain. Design Retrospective review 2 large case series patient responses versus combined corticosteroid. Setting Private practice chronic clinic set in hospital outpatient clinic. Participants Patients (N=120) sequentially enrolled billing records. Inclusion criteria included low back below L4 buttock, thigh, groin, or lower leg. If disk herniation, lumbar stenosis, facet syndrome was previously treated appropriately chosen injections, response treatment had be negative. failed respond physical therapy. Exclusion records an incomplete database, patients increasing medication use greater than 15% not related region, severe psychiatric illness, nonspecific blockade. One hundred sixty-seven were reviewed obtain 120 subjects. Interventions Intra-articular done according described by Fortin. Peri-articular slight modification procedure Yin. Main Outcome Measures Percentage change visual analog scale (VAS) scores at 3 weeks months postinjection; patients' self reported activities daily living (ADLs) improvement percentage VAS score within 1 hour Results For alone, rate positive 12.50% 31.25% ( P =.025). Positive defined as 50% drop describing ADLs "greatly improved." Anesthetic rates higher group (62.5% vs 42.5%; =.037). Conclusions Significant exist. diagnostic blocks
