Sacroiliac joint fusion for chronic pain: a simple technique avoiding the use of metalwork

A previously undescribed method for posterior fusion of the sacroiliac joint (SIJ) utilizing the Cloward instrumentation is presented, suitable for cases with chronic pain and intact ligamental structures of the SIJ. The advantages of the method in comparison with other described options include minimal disturbance of the periarticular structures, avoidance of introduction of metalwork and preservation of the iliac crest contour. This technique has been used in five cases with follow-up longer than 2 years (mean 29 months, range 25-41 months). In all cases there was resolution of their painful symtomatology.
