What is sacralization of the spine and how to live with it?

• lower back pain – often resulting from overloading of spinal structures or possibly inflammation of the sacroiliac joints;
• limited mobility – particularly when bending or straightening the lower back;
• radiating pain to the legs – caused by compression of nerves located near the fused structures;
• increased stiffness – especially in the morning or after prolonged sitting, mainly among individuals with sedentary jobs.

What is sacralization of the vertebrae?

Sacralization of the vertebrae is an anatomical anomaly of the spine where the fifth lumbar vertebra (L5) fuses with the sacrum. This fusion can be complete or partial. It is often discovered incidentally during imaging tests such as X-rays, CT scans, or MRI.

What does sacralization in the spine mean?

Sacralization in the spine means that the fifth lumbar vertebra fuses with the sacrum, forming a single, immobile structure. It is typically a congenital defect but can also develop due to degenerative changes with age. While sacralization does not always cause symptoms, it can lead to back pain, reduced mobility, or overloading of adjacent structures in some individuals.

How does sacralization differ from lumbarization?

Sacralization refers to the complete or partial fusion of the fifth lumbar vertebra (L5) with the sacrum. In contrast, lumbarization occurs when the first sacral vertebra (S1) fails to fuse with the rest of the sacrum, resembling an additional lumbar vertebra. Both are anatomical anomalies that may, but do not necessarily, cause pain or other symptoms.

Is lumbarization of the spine dangerous?

Lumbarization of the spine itself is not dangerous but can lead to spinal overloading or other issues. These may include back pain, limited mobility, or problems with adjacent joints. Accurate diagnosis is crucial. If necessary, therapy or exercises that support spinal health are recommended.

How do you know if spinal surgery is needed?

The decision for spinal surgery is made by a doctor based on thorough diagnostics, symptoms, and the condition's impact on daily functioning. Spinal surgery is recommended in cases of severe functional disorders, such as intense, chronic pain, nerve compression, or significant mobility limitations that do not respond to conservative treatment. Surgery for sacralization is rare and is performed only in exceptional cases.
