In T-bone accidents, the driver who acted negligently on the road by not following traffic signs or committing traffic violations is usually at fault. However, while it may appear that the driver who collided with the other vehicle is responsible for the accident, this is not always the case.
In a multi-car accident, determining fault requires a careful examination of all available facts. Each car accident is unique, and blame for the incident falls on the person or parties responsible. The person responsible for an accident, or his or her insurance company, will bear the major financial responsibility. To determine who is to blame, it is essential to gather sufficient evidence to prove what happened.

In a rear-end auto collision, spinal injuries of the neck and back often occur. A traumatic facet joint injury to the spine as a result of a rear-end auto crash is a common injury. Facet joint injuries are an “invisible” injury. A traumatic facet joint injury is usually not seen on X-rays and MRI imaging studies.

The attorneys at the law firm of Grazian & Volpe have handled hundreds of auto crash cases and understand the medicine related to a facet joint injury in the spine. In this Blog, which is part of a series on spinal injuries caused by auto accidents, we shall explain what a facet joint injury is, how a facet joint injury is diagnosed, and what is done to treat a facet joint injury.

Facet Joints

The facet joints help stabilize our spine, holding the spinal column in place and preventing excessive rotation (twisting) and flexion or extension (bending) of the spine.

Facet joints also prevent rotation of the vertebral column to a great degree. In addition, facet joints are necessary to prevent spondylolisthesis, which is forward slippage of one vertebra upon another. When this injury happens, the spinal canal gets compromised and there can be problems with pinching of the spinal cord.

Signs and Symptoms of Facet Joint Injuries

  • Acute onset of neck, mid or low back pain.
  • Palpable tenderness directly over the facet joints and reduced range of motion and muscle spasms.
  • In the neck, pain increases when extending backward and improves when flexing forward.
  • In the low back, pain can radiate or extend from the back to the buttocks; pain is present when standing but increases with sitting.
  • In the neck, the pain can radiate or extend from the neck onto the top of shoulders and upper shoulder blades.
  • The pain and restricted motion are recurrent and ongoing.

Diagnosis of Facet Joint Injuries

A CT-scan at the spinal level involved is the imaging study of choice for clinically suspected facet joint injuries. However, a CT-scan is only sensitive for diagnosis of damage to the facet joint fifty percent (50%) of the time.

The best diagnostic method for facet joint injuries is a medial branch block procedure. The medial branch nerves supply sensation and enervation to the facet joints. During a medial branch block procedure, an anesthetic is injected in the spine near the small medial nerves connected to a specific facet joint.¹

Usually, a medial branch block is performed on two different dates, months apart, to confirm the diagnosis.

Long Term Treatment of Facet Joint Injuries

A procedure known as radiofrequency ablation (“RFA”) is used to treat a facet joint injury and obtain long term relief. An RFA is a minimally invasive procedure that reorganizes and modulates the nerve fibers carrying pain signals to the brain. In a radiofrequency ablation procedure, also called a rhizotomy, a probe is placed in the spine under x-ray guidance, and heat wave energy is delivered to the affected nerves. The waves “ablate,” or burn, the nerves that are causing the pain, thereby stopping pain signals from traveling along the nerves to the brain.
