Why is it called tetraplegia now?

If your loved one’s records say tetraplegia and a report says quadriplegia, you are not imagining it. Both words appear in hospitals, research papers, and court filings.

This page explains what the sources say about the wording. It also explains what they do not say. Then it explains what the difference means for your family.

The Short Answer: The Word Changed, the Injury Did Not

Tetraplegia and quadriplegia describe the same pattern. Both mean reduced movement and feeling in the arms, hands, trunk (the main part of the body, from shoulders to hips), and legs. The pelvic organs, such as the bladder and bowel, are often affected too.

The pattern usually follows an injury to the cervical spinal cord. This is the part of the spinal cord that runs through the neck.

The University of Alabama at Birmingham describes tetraplegia as the loss of voluntary movement (movement a person can control) in the upper and lower body. It notes that the term is sometimes still called quadriplegia.

What the Sources Do and Do Not Establish

We reviewed the sources behind this page. They define and distinguish the two terms.

They do not document a dated change in terminology. They also do not state a specific reason one word replaced the other. So this page gives no date and no reason for a switch.

Here is what we can say. Some medical and rehabilitation writing uses “tetraplegia.” Other writing, and most everyday conversation, still uses “quadriplegia.”

Your doctor’s word and a report’s word can differ. Both can still describe the same injury.

The Word Roots: Latin, Greek, and a Cleaner Match

“Quadriplegia” mixes two languages. “Quadri” is Latin for four. “Plegia” is Greek for paralysis.

“Tetraplegia” uses Greek for both parts. “Tetra” is Greek for four. “Plegia” is Greek for paralysis. Some writers prefer this consistent word origin.

The medical meaning is the same either way.

The Core Distinction: Tetraplegia Versus Paraplegia

The clearest way to tell these conditions apart is arm function. The World Health Organization separates the two by whether the arms are affected:

• Paraplegia: Arm function is preserved. The legs and trunk are affected.
• Tetraplegia: Arm function is affected, along with the legs and trunk.

MedlinePlus, the consumer health information service of the U.S. National Library of Medicine, describes the same neck-versus-mid-back pattern.

An injury in the neck (cervical) region tends to affect the arms as well as the legs. An injury at mid-back (thoracic) level usually spares the arms. It affects the legs and trunk.

Spine location is the main factor, but it is not the only one. Whether the injury is complete or incomplete also matters. A complete injury means no movement or feeling below the injury. An incomplete injury means some function remains.

Mayo Clinic explains these patterns in its spinal cord injury overview. Our guide on paraplegia vs. quadriplegia compares the two in more detail.

Are Quadriplegic and Tetraplegic the Same?

Yes. The two terms mean the same thing. Both describe reduced movement and feeling in all four limbs and the trunk.

How much function a person keeps can vary. It depends on the injury level, on whether the injury is complete or incomplete, and on the individual.

Are Quadriplegics Paralyzed From the Neck Down?

Often, but not always in the same way. The injury usually occurs at the neck level. So effects often begin at or below the neck.

Some people keep partial arm or hand movement.

Clinicians measure this with the ASIA Impairment Scale. It is part of the International Standards for Neurological Classification of Spinal Cord Injury from the American Spinal Injury Association. The scale grades muscle strength and sensation (feeling).

Only a clinical exam can grade one person’s injury. Please follow your care team’s diagnosis and guidance.

What Causes Tetraplegia?

Serious accidents and violence are among the leading causes. Mayo Clinic lists car crashes, falls, and acts of violence among the most common causes of spinal cord injury.

Consider a common situation. A person is assaulted or shot in a parking garage at an apartment complex. Or a guest is attacked in a hotel hallway.

The property owner did not keep working locks, gates, lighting, cameras, or guards. These could have prevented the attack. Every situation is different, so the specific facts of each case matter.

Lawyers call this kind of claim “negligent security.” You do not need that term to know that something went wrong.

A tetraplegia diagnosis is life-altering. It is often permanent. It can bring lasting medical and financial effects.

For data, the National Spinal Cord Injury Statistical Center is a main U.S. source for spinal cord injury figures. The Christopher & Dana Reeve Foundation publishes paralysis statistics.

What Families Facing a Catastrophic Spinal Cord Injury Can Do Next

Whatever the word, tetraplegia usually means lifelong care needs. Families often face adaptive equipment (tools and devices that help with daily tasks), home changes, and years of therapy and support.

If the injury came from a serious crash, or from a property owner’s failure to keep people safe, your family may have legal options. In the catastrophic-injury cases that CHG Personal Injury Lawyers handles, a claim can seek compensation for medical bills, lost income, and long-term care.

Florida law sets deadlines for filing injury claims. Fault rules can affect how a claim is valued. Deadlines apply. Contact the firm promptly.
