What is a biconcave fracture?

Biconcave compression fractures are the second-most common, accounting for approximately 17% of all VCFs37 (Figure 1b and ​ 1c). In these fractures, only the middle portion of the vertebral body is collapsed, whereas the anterior and posterior walls remain intact. The least common VCFs are crush compression fractures.

What is compression fracture with Retropulsion?

Compression fractures are characterized radiographically by loss of vertebral height, retropulsion of bone into the spinal canal, and kyphotic angulation.

Will MRI show vertebral fractures?

An MRI scan shows a high level of detail of the soft tissues (e.g. nerves, discs) surrounding the fracture that may be affected. An MRI scan can also tell if the fracture is old or new.

What is Retropulsion of the spine?

A retropulsed fragment is any vertebral fracture fragment that is displaced into the spinal canal, thereby potentially causing spinal cord injury. They usually arise from the vertebral body with or without a portion of the pedicle, and are displaced posteriorly, hence the prefix ‘retro’.

Will an MRI show an old fracture?

An MRI scan uses magnetic fields to create computer-generated images of the inside of the body. It’s especially helpful if doctors need to distinguish between a fracture that is actively healing and an older fracture that has not healed.

What causes Retropulsion?

Retropulsion occurs due to a worsening of postural stability and an associated loss of postural reflexes. You may be familiar with the “pull test” that your neurologist performs to check your stability. Your doctor will stand behind you and then give you a forceful tug at your shoulders.

Is a fractured spine serious?

Even minor falls or trauma can produce a spine fracture. Many of these injuries will never require surgery, but major fractures can result in serious long-term problems unless treated promptly and properly.

How painful is a spinal fracture?

The pain from an osteoporotic spinal fracture typically lasts about four to six weeks as the bone heals, after which most patients report that the more severe pain has subsided and has turned into more of a chronic, achy pain concentrated in the area of the back where the fracture occurred.

When to know if you have a vertebral compression fracture?

Vertebral fracture should be diagnosed when there is loss of height in the anterior, middle, or posterior dimension of the vertebral body that exceeds 20%.

What makes the thoracolumbar junction more prone to fractures?

This segment is between T12 and L2 and is considered a transition zone from the more rigid thoracic vertebral column to the relatively mobile lumbar vertebral column. This anatomic relationship makes the thoracolumbar junction more prone to fractures than the rest of the spine.

How are compression fractures of the spine treated?

When vertebral compression fractures become symptomatic and cause disability, several treatment options are available, including kyphoplasty to alleviate pain and correct the sagittal imbalance of the spine.

What is the compression mechanism of the thoracolumbar spine?

Compression fractures of the thoracolumbar spine have a flexion compression mechanism of injury. This mechanism usually involves the first column (anterior longitudinal ligament and anterior half of the vertebral body).
