Posterior Lateral into the Longitudinal Joint Axis Approach: Minimally Invasive

This chapter will discuss the unique nature of this approach and fixation that allow it to be minimally invasive and yet highly effective in achieving surgical goals. Its etiology as an Investigational Review Board (IRB) hospital study will be discussed as well as limitations based on the lack of current FDA approval for implanting instrumentation in the longitudinal axis of the sacroiliac joint (SIJ). The indications, contraindications, and specific technical challenges to this procedure will be discussed as well as relative outcomes. Lastly, the method of salvaging this procedure in the event of failure will be discussed as well as using this approach for SIJ aspiration and biopsy in the event of suspected joint infection or other pathologic process.
