Sacroiliac joint pain (SIJP) after lumbar/Lumbosacral fusion: Our experience
Objective: To evaluate risk factors for SIJP following lumbar or Lumbosacral fusion in our population.
Methods: This retrospective study was conducted in Orthopedic and Spine department of Ziauddin University hospital Karachi. Patients meeting inclusion criteria were included. Incidence of SIJ pain following lumbosacral fusion surgery and its associated risk factors were assessed.
Results: 597 patients were included, 256(42.9%) were males and 341(57.1%) were females with mean age of 58.3 +/- 14 years. L4-L5 was most common involved segment in 49.1% cases followed by L3-L4 (30.5%) and L5-S1 (10.1%). Floating fusion was performed in 401 (67.2%) cases while fixed fusion was performed in 196(32.8%). Lumbar canal stenosis was most common diagnosis followed by LDH and spondylolisthesis. SIJ pain developed in 81 (13.6%) patients within 6-12 months in most of cases. Significant relationship was found between SIJ pain with more than 3 levels lumbar fusion (p-value=0.000), fixed fusion involving S1 (67/81 pts, p-value=0.000). No significant association was found between SIJ pain with age, gender, smoking, comorbidities, spinopelvic balance and degenerative scoliosis.
Conclusion: Multilevel fusion and fixed fusion are interrelated risk factors for development of post operative SIJ pain.
