Article Synopsis
- This study is a retrospective analysis focusing on the occurrence of sacroiliac joint pain (SIJP) after multisegment spinal fusion surgery, which is becoming more common.
- It involved 77 patients divided into groups based on the type of lower fixation used (L5, sacrum, or pelvis) to assess the incidence of SIJP and proximal junctional kyphosis (PJK).
- The results showed that the SIJP incidence was highest in the sacrum group, whereas it was very low in the pelvis group, suggesting that fixation techniques might play a role in preventing SIJP.
Repeated Low Back Pain Caused by Regional Migratory Osteoporosis of the Sacroiliac Joint.
J Orthop Case Rep
January 2018
Introduction: Regional migratory osteoporosis (RMO) is a rare, self-limiting disorder characterized by migratory arthralgia that mainly occurs in the weight-bearing joints of the lower extremities. RMO is most commonly observed in middle-aged men, and its etiology is unknown. We report the case of a middle-aged man who experienced repeated low back pain that was caused by RMO of the sacroiliac joint (SIJ).

We aimed to develop a simple clinical diagnostic tool to help physicians distinguish between patients with SIJ pain originating from the posterior ligament and those with lumbar disc herniation (LDH) or lumbar spinal canal stenosis (LSS).
Design: Prospective case-control study.
Study Design: A retrospective study.
Objective: To determine the risk factors for sacroiliac joint pain (SIJP) after lumbar or lumbosacral fusion.
Summary Of Background Data: Recently, the sacroiliac joint has gained increased attention as a source of pain after lumbar or lumbosacral fusion.
Objectives: To determine the validity of posterior lumbar interbody fusion (PLIF) using a titanium cage filled with excised facet joint bone and a pedicle screw for degenerative spondylolisthesis.
Methods: PLIF using a titanium cage filled with excised facet joint bone and a pedicle screw was performed in 28 consecutive patients (men 10, women 18). The mean age of the patients was 60 years (range, 52 to 75 y) at the time of surgery.
