Case Study Report

Background
and Purpose: Three cases with loss of passive pelvic macromotion (PM) and
sacroiliac joint (SIJ) micromotion (SIJM) are presented. Case one (C1) had an
H1N1 virus infection with pathological left SIJ fusion. Case 2 (C2) presented
with an extensive thoracic and lumbosacral fusion who requested consultation,
anticipated a SIJ fusion. Case three (C3) was an athlete treated because of
significant and lasting drop in performance. Description: The purpose of this
case series is to compare passive SIJM and PM loss with objective imaging (CT
scan) and explore diagnostic utility of SIJM and PM in a case of early,
not-yet-diagnosed inflammatory spondylarthropathy (IS). Outcomes: Unilateral
loss of PM and SIJM in C1 and C2 correlated positively with unilateral SIJ
fusion per CT scan. Normal joint space at S1 and S2 and absence of joint space
at S3 from hardware invasion was observed in C2. Inability to gain PM, SIJM in
C3 aroused suspicion of SIJ pathology and provoked rheumatologic referral.
Discussion and Conclusion: The PM and SIJM tests correlate with fused SIJ’s,
have utility for a subset of subjects who contemplate SIJ fusions, and for early
detection of IS in which early SIJ fibrotic changes may escape early detection,
delaying definitive diagnosis up to 10 years from initial onset.
