Blood test may predict which back injuries heal without surgery

This study looked at 130 people with lumbar disc herniation (slipped disc) to see if a blood-based measure called the Systemic Immune-Inflammatory Index (SIII) could help predict whether the disc would shrink naturally or require surgery. Researchers compared blood test results between those who had surgery and those treated with medication alone. The goal was to better understand the body's natural healing process, not to test a new treatment.
