How do you get pars interarticularis?
The pars interarticularis or simply pars is the part of a vertebra located between the superior and inferior articular processes. In the axial plane the pars is located at the junction of the pedicle and lamina. In the oblique lumbar radiograph, the neck of the Scottie dog represents the pars.
What is the function of pars interarticularis?
Pars Interarticularis, Structural Forces and Stress The joints above are connected to the joints below in one vertebra through the pars interarticularis. The pars interarticularis means the “part between the articulations” in Latin and is the bony bridge that joins these two upper and lower facets.
Can an X-ray show spondylolysis?
Doctors use X-ray imaging to take detailed pictures of your spine. X-rays can reveal a stress fracture in the pars interarticularis. An X-ray may be all a doctor needs to diagnose spondylolysis.
How is a pars fracture treated?
The treatment for a pars fracture is initially nonsurgical and includes rest and bracing. The fracture can be assessed with a series of X-rays every few months.
Where are the pars interarticularis?
Pars interarticularis refers to a small segment of bone that joins the facet joints in the back of the spine.
Can a MRI detect pars fracture?
Conclusions: MRI is an effective method (92% sensitivity) for detecting pars injuries. It can detect stress reactions when a fracture is not visible on CT scan, allowing early treatment of these prelysis lesions.
How long does a pars fracture take to heal?
Early stress fracture. A visible early hairline fracture can heal with two to three months of rest in more than 90 out of 100 cases. The chances of healing are significantly higher if the fracture is in one side of the vertebral body, rather than both sides.
How serious is a pars fracture?
Another term for spondylolysis is “pars fracture” or “pars defect”. This defect can lead to low back pain and in some cases, to instability of the bones. Spondylolysis can cause the bone with the stress fracture to slip forward on top of the bone below.
