The normal range of motion (ROM) of the sacroiliac joint (SIJ) has been measured in various ways and has been found to be minimal under normal conditions (Buchowski et al., Spine J 5:520–528, 2005; Foley and Buschbacher, Am J Phys Med Rehabil 85:997–1006, 2006; Katz et al., J Spinal Disord Tech 16:96–99, 2003; Walker, Phys Ther 72:903–916, 1992). There are clinical situations where the SIJ has been “out of alignment” or has been “realigned” by the clinician based on external anatomical clinical findings. Controversy continues to exist regarding SIJ ROM in terms of stability in both clinical and surgical situations. This chapter discusses what happens to the ROM of the SIJ when the posterior supporting ligament structures are sequentially transected after which adjacent joint (L5–S1) stabilization is performed. Clinical relevance is then discussed based on these findings. |
