Pricing and Availability Upon Request

Contact us: sales@gpianatomy.com

Grade 3 spondylolisthesis, a defect in the pars interarticularis of the posterior vertebral arch. A common cause of axial back pain in adolescents, especially young athletes, the defect typically occurs in the lumbar spine, most often at L5. 

Spondylolysis can persist to become spondylolisthesis, in this case anterolisthesis. Typically, the L5 vertebral body slips forward on the S1 vertebral body, but also commonly occurs at the L4 and L5 levels. Patients unresponsive to conservative measures may benefit from surgical management. 

Designed using real patient imaging scans and the latest 3D printing technologies, in collaboration with Mayo Clinic.

About the Condition

What Is Spondylolysis?

Spondylolysis is a stress fracture that occurs between two vertebrae in the spine. The vertebrae are a series of 33 small bones stacked on top of each other that surround the spinal cord and nerves. They are connected by tiny bones called the pars interarticularis, which allow the spine to flex and move. When fractured, the pars bone cracks on one or both sides where it connects to the vertebrae. 

Most cases of spondylolysis result from repetitive motions or overuse as a result of sports, especially in children and adolescents. When present, symptoms may include a dull ache in the lower back and tightness in the buttocks and hamstrings. Spondylolysis typically occurs in the lumbar spine in the lower back, but it can also occur in the thoracic spine in the middle of the back or in the cervical spine in the neck.

How Common Is Spondylolysis?

Spondylolysis is a common cause of low back pain in young athletes, with up to 15% experiencing it. However, the majority of people with the condition have no symptoms. 

Males are more likely to experience spondylolysis than females. The condition can also be caused by genetics in people who have thinner pars bones in the spine, and from degenerative wear and tear on the spine as a result of aging.

What’s the Difference Between Spondylolysis and Spondylolisthesis?

When a stress fracture in the spine doesn’t heal, the vertebrae can weaken and slip out of place. This condition is called spondylolisthesis. The fractured vertebra slides forward or backward, pressing on the nerves and bones underneath it. This can cause low back pain and shooting pain in the legs, called sciatica. 

How Is It Treated?

Treatment for spondylolysis and spondylolisthesis typically requires a combination of rest, physical therapy and wearing a back brace for a period of time. If symptoms don’t improve or worsen, surgery may be performed to repair the pars fracture or to fuse the vertebrae together to relieve pressure on the nerves and restore mobility.

Benefits of 3D Printing

3D-printed anatomy models offer a variety of advantages for surgical planning, patient education and medical research, including:

∙ Greater accuracy and detail than traditional anatomical models. 3D-printed models are created from digital scans of a patient's anatomy, which ensures that they are as close as possible to an exact replica of real human anatomy.

∙ More versatility than traditional anatomical models. 3D-printed models can be customized to meet your specific needs, whether planning a complex surgical procedure, training with real patient data or facilitating personalized patient communication.

Not limited to standard manufacturing, 3DP provides the best opportunity to produce accurate models in natural organic shapes, sizes, and colors; creating the best representation of real human anatomy.
