What is slippage of SI joint?

Slippage of the sacroiliac (SI) joint refers to abnormal movement or displacement of the joint where the sacrum meets the ilium of the pelvis. This condition can lead to pain, stiffness, and instability in the lower back and hips. It may occur due to injury, inflammation, or degenerative changes, and can sometimes be associated with conditions like pregnancy or Arthritis. Treatment often involves physical therapy, pain management, and, in some cases, surgical intervention.
