Pelvic Fixation / Deformity

Lumbopelvic fixation failure rates are high following adult spinal deformity (ASD) correction

Approximately one quarter (24%) of ASD patients reported lumbosacral and pelvic fixation failure within a 2-year follow-up, leading to revision surgery.¹²²

More Levels. More Stress.

A 2009 paper published in Spine by Ivanov showed fusing L5-S1 and L4-S1 increased the motion (stress) of the sacroiliac joint by 52% and 168%, respectively.¹¹²

SI joint pain is a potential cause of lower back pain after lumbar or lumbosacral fusion surgeries. One study indicated that fusion of multiple segments (at least 3) can increase the incidence of SI joint pain up to 23%.¹²³
