Sacroiliac joint pain

ANATOMY OF THE SPINE

The human spine is formed by individual vertebrae and connective tissue discs in between. The vertebrae form the spinal canal. There are seven cervical, twelve thoracic, and five lumbar vertebrae. The intervertebral discs are the link between the individual vertebral bodies.
Normal anatomy of the spine. Longitudinal section and cross sections through the cervical, thoracic and lumbar spine.
The little joints that link the vertebrae together are known as facet joints. They help to stabilize the spine and, together with the intervertebral discs, allow a certain degree of mobility of the spinal cord. The spinal canal should be wide enough to allow nerve roots to float freely in cerebrospinal fluid. The front border of the spinal canal is built by the vertebral bodies and intervertebral discs, the side by the intervertebral joints (facets) and back by the ligamentum flavum (yellow band) and vertebral arches. Discs consist of an outer fibrous ring (annulus fibrosus), which surrounds an inner gel-like center (nucleus pulposus). The spinal cord and nerve roots lie within the spinal canal. The spinal cord extends downwards approx. to the 1st lumbar vertebra. Below, only nerve roots are present in the spinal canal. At the level of the intervertebral disc the nerve roots pass through the neural root foramina to exit the spinal canal. The spinal cord and nerve roots conduct electric-like signals from the skin and joints to the brain, and process of movement is initiated from the brain to the muscles.

DESCRIPTION

Lower back pain is one of the most common causes for people to seek medical advice. Trauma, hyper or hypomobility of the sacroiliac joints often lead to aseptic inflammation. Sacroiliac joint pain is experienced in the lower back. In young patients, sacroiliac joint pain could be an early symptoms of Ankylosing spondylitis (Bechterew's disease).

CAUSE OF SYMPTOMS

Gradually progressing inflammation and degeneration in the sacroiliac joints

SYMPTOMS AND SIGNS

Pain in the lower back. Usually the pain is strongest early in the morning and weakens while walking.. Pain in one or both legs (pseudorrahular type)

THE DIAGNOSIS IS BASED ON

Medical history Clinical exam
Sacroiliac joint block
and at least one of the following tests:
Magnetic resonance imaging (MRI) Computer tomography

TREATMENT

The treatment may be non-surgical or surgical.
Non-surgical treatment may include
Physiotherapy Physical exercise
Strengthening the back muscles
Treatment with heat (Fango) Nonsteroidal anti-inflammatory drugs Antidepressants
Sacroiliac belt
How to wear a Sacroiliac Belt
Therapeutic corticosteroid infiltrations

WHEN SHOULD AN OPERATION BE PERFORMED?

At least 2 months of conservative treatment cannot relieve pain significantly

WHAT IS THE GOAL OF SURGERY?

To destroy the nerve endings that carry the pain from the facet joints
Override pain by neuromodulation

HOW IS SURGERY PERFORMED?

Percutaneous cryoablation
Percutaneous radiofrequency thermoablation
Endoscopic sacroiliac joint denervation
Neuromodulation
Arthrodesis (surgical joint fusion)

WHICH OTHER DISEASES SHOULD BE EXCLUDED (DIFFERENTIAL DIAGNOSIS)?

Tumor of the spine Vertebral fractures
Diseases of the hip or knee
Infections and inflammations of the spine Facet joint pain / Back pain Disc herniation Arthritis
