Intraartecular Platelet Rich Plasma for Sacroiliitis

At the level of the sacral hiatus, the sacral cornuae were identified. posterior aspect of the sacroiliac joint, at 4.5 cm depth the SIJ was found. localal anesthetic was injected at the medial edge of the transducer, the spinal needle was advanced in a medial to lateral direction, under direct vision, until the needle was positioned in the SIJ. Local steroid solution or PRP 4ml volume was injected according to the study group and patient enrollment. If the injection is extra-articular, injectate (hyperechoic solution as it contains particulate steroid) can be seen spreading medially over the sacrum. The visual analog score, Oswestry Disability Index (ODI) score and the overall success rate basal, after one week,after one month,after three and six month's follow-up period after the initial block.
