We recently conducted an ultrasound-guided sacroiliac (SI) joint intra-articular injection feasibility study. We used six non-fresh formaldehyde-embalmed wholebody human cadavers (12 SI joints).
The cadavers were embalmed with a standard formaldehyde-embalming method for anatomy dissection lectures (fig 1). All injections were performed by a board-certified physical medicine and rehabilitation physician who is familiar with this method.
A portable ultrasound machine with 2-5 MHz curvilinear array probe was used (UGEO HM70A, Samsung, Seoul, South Korea). For injection, we followed the protocol described by Chang et al.
However, we faced few serious difficulties. Therefore, we feel obligated to share our experience regarding our study.
