Question: What Is A Type 3 Odontoid Fracture?

What is a Grade 4 stress fracture?

grade 4: severe marrow edema on both fat-suppressed T2WI and T1WI or periosteal edema plus visible fracture line on T1WI or T2WI..

How serious is a c7 fracture?

Severe trauma to this level may also injure the spinal cord. In rare cases when the C7 vertebra forms a cervical rib, compression of surrounding blood vessels and/or nerves may occur, resulting in thoracic outlet syndrome.

What happens if you fracture your c2?

In addition to the initial vertebral injury, the interference at the C1 and/or C2 level can cause the vertebral arteries to inflict neurological damage; leaving the brain without a vital source of blood. Symptoms following an injury to the cervical vertebrae C1 and C2 may include: Complete paralysis of arms and legs.

What is an Odontoid fracture?

Fracture = A break in a bone. A type II odontoid fracture is a break that occurs through a specific part of C2, the second bone in the neck. Bones of the spine are called vertebrae. The bone involved in odontoid fracture is the second vertebra, C2, high up in the neck.

What is a Type III fracture?

Type 3. This fracture occurs when a force hits the growth plate and the rounded part of the bone, but doesn’t involve the bone shaft. The fracture may involve cartilage and enter into the joint. This type usually happens after age 10. About 10 percent of Salter-Harris fractures are type 3.

What is a c2 fracture?

The hangman’s fracture refers to a break in a bone known as C2, because it is the second bone down from the skull in your cervical (neck) vertebrae. A fracture can be a partial or complete break in a bone. The injury can also cause the C2 to move out of alignment with the bone right below it, known as the C3.

What is a Grade 3 open fracture?

Grade III open fractures represent the most severe injuries and include three specific sub-types of injuries:1Grade IIIA: 3A fractures are those injuries that include high-energy fractures as evidenced by severe bone injury (segmental or highly comminuted fractures) and/or large, often contaminated, soft-tissue wounds …

Is the dens on c1 or c2?

Cervical spine. Note uniquely shaped atlas and axis (C1 and C2). The atlas is ring-shaped and does not have a body, unlike the rest of the vertebrae. Fused remnants of the atlas body have become part of C2, where they are called the odontoid process, or dens.

What is a Jefferson fracture?

Jefferson fracture is the eponymous name given to a burst fracture of the atlas. It was originally described as a four-part fracture with double fractures through the anterior and posterior arches, but three-part and two-part fractures have also been described.

How do you get a Jefferson fracture?

The Jefferson fracture occurs most likely because of a diving accident (striking the bottom of the pool) with hyperextension of the cervical spine or may result from an axial load on the posterior side of the head. It may also result from an impact against the roof of a vehicle.

Can you survive a hangman’s fracture?

Although a hangman’s fracture is unstable, survival from this fracture is relatively common, as the fracture itself tends to expand the spinal canal at the C2 level. It is not unusual for patients to walk in for treatment and have such a fracture discovered on X-rays.

When should I worry about neck injury?

Don’t medically investigate neck pain until it’s met at least three criteria: (1) bothering you for more than about 6 weeks; (2) severe and/or not improving, or actually getting worse; and (3) at least one other “red flag”: age over 55 or under 20, painful to light tapping, fever/malaise/nausea, weight loss, nasty …

Can you survive a c2 fracture?

However, they are also considered to be the worst spinal cord injury that it is possible to sustain, and often fatal. For patients who survive, treatment and outcomes for C1 and C2 injuries can vary greatly between individuals.

Can you break your neck and not realize it?

The most common symptom of hangman’s fracture is neck pain following a fall or motor vehicle accident. However, if the trauma has caused other damage to the body, the neck pain may not be immediately noticed. Therefore, prompt medical evaluation is necessary after any such trauma.

What is spinal immobilization and why is it used?

The theory behind this is that spine immobilization prevents secondary spinal cord injury during extrication, transport, and evaluation of trauma patients by minimizing movement.

What does c2 affect?

If the spinal cord becomes compressed at the C2 level, it can cause pain, tingling, numbness, and/or weakness in the arms or legs, loss of bowel and/or bladder control, and other problems. Severe cases of spinal cord injury at C2 can be fatal because breathing and other critical body functions may be impaired or stop.

Which vertebra has an Odontoid process?

second cervical vertebraThe axis is the second cervical vertebra, commonly called C2. It is an atypical cervical vertebra with unique features and important relations that make it easily recognisable. Its most prominent feature is the odontoid process (or dens), which is embryologically the body of the atlas (C1) 1,2.

How long does it take to heal a c2 fracture?

Treatment for type I C2 (axis) fractures is hard-collar immobilization for 6-8 weeks, which usually is quite successful. Type II fractures can be managed conservatively or surgically.

What does the Odontoid process do?

The odontoid process lies anterior to the spinal cord and is used as the pivot for the rotation of the head. The C1 vertebra, carrying the cranium, rotates on this. The craniovertebral joint between the atlas and the axis is called, the atlanto-axial joint.

Why is it called a Jefferson fracture?

It is named after the British neurologist and neurosurgeon Sir Geoffrey Jefferson, who reported four cases of the fracture in 1920 in addition to reviewing cases that had been reported previously.

What are the 7 types of fractures?

Types of FracturesGreenstick – Incomplete fracture. … Transverse – The break is in a straight line across the bone.Spiral – The break spirals around the bone; common in a twisting injury.Oblique – Diagonal break across the bone.Compression – The bone is crushed, causing the broken bone to be wider or flatter in appearance.More items…
