What does "chronic bilateral pars defects at l5" mean?

Pars defect: Refers to the pars interarticularis which is the bone connecting the inferior and superior facets which is anterior to the lamina and posterior to the pedicle. There are two per vertebrae. Lumbar pars defects can occur in young athletes or from stress fractures secondary to chronic arthritic changes or sudden severe trauma. ...Read more

Pars Defect (Definition)

Spondylolysis is a defect of a vertebra. More specifically it is defined as a defect in the pars interarticularis of the vertebral arch. The great majority of cases occur in the lowest of the lumbar vertebrae (l5), but spondylolysis may also occur in the other lumbar vertebrae, as well as in the thoracic vertebrae. Spondylolysis occurs in three to six ...Read more

Surgical risks: It sounds like you have chronic back pain, and that surgery(ies) have not been helpful. The problem with MRI scans of the spine is that they are good at identifying structural changes but do not let us know what is causing the pain. The changes you note on the MRI are common age associated changes. I suggest you see a physical medicine & rehab doctor (non-surgeon) who specializes in the spine. ...Read more

What does Bilateral L5 pars fractures with grade 1 anterolisthesis of L5 S1 and L5 S1 mild to moderate diffuse disk bulge mean?

See below : There is a term called isthmic spondylolisthesis that summarizes what you have. Basically at some point you developed a fracture in a part of the spine known as the pars interarticularis and this allowed one of your vertebrae to shift forward on the other. It is a fairly common cause of back and leg pain. Many good treatment options. Discuss directly with your doctor. ...Read more

Not sure of your ?: If you're asking about the imaging results you posted, you have a bone spur that is growing off of two of your vertebrae. It is large enough that it is pressing against your spinal cord and possibly some of the nerves that are exiting from the spinal cord. Your doctor will recommend treatment based on the severity of your symptoms. ...Read more

Can L4 anterolisthesis & L5 posterolisthesis on s1 with bilateral pars defect at L4 cause venous insufficiency in both legs? If so why?

Can L4 anterolisthesis & L5 posterolisthesis on s1 with bilateral pars defect at L4 cause venous insufficiency in both legs? If so why?

No: Bone, and discs, not vascular and would be incredibly unusual to slip, enough to compress major veins. Trauma, coagulopathy, DVT lead to venous valvular leakage- insufficiency. ...Read more

Grade 1 anterolisthesis of L5 over s1 with fatty marrow conversion at left L5 pars inter articular with bowing indicative of a healed fracture, 22yo/m?

Spondylolisthesis L5: You have described what is probably a congenital condition with a defect in the pars interarticularis. The symptoms may have become apparent after some trauma. 90% of the time people of this condition can be treated conservatively with a lumbosacral brace and analgesics. If symptoms worsen, further imaging may include MRI or ct with intrathecal contrast. Decompression and fusion may become neces. ...Read more

I have bilateral foraminal stenosis present at l4l5 with bilateral pars defect at L4 and am curious if the pars and stenosis can heal without surgery?

I have bilateral foraminal stenosis present at l4l5 with bilateral pars defect at L4 and am curious if the pars and stenosis can heal without surgery?

Generally, symptoms : Can resolve due to either condition the majority of the time without surgery as the only reason for surgery would be a failure of nonop care to control symptoms. If the pars defect was an acute fracture it has the potential to heal without surgery. But even if it doesn't or if not an acute fracture type, 90% are treated non op while only 15% of stenosis cases end up with surgical intervention. ...Read more

Lumbar stenosis: Lumbar spinal deformities in form of varying degrees affects 6% of the population in the U.S,..THE treatment spectrum varies from avoiding activities that produce pain, bracing , physiotherapy, NSAIDs, to surgical interventions which involve decompress ions and or fusions. Recovery from surgery depends upon whether or not a fusion is performed , but can take up to 9-12 months. ...Read more

What is bilateral pars defect of the spine?

Lumbar Pars Defect: The defect is a stress fracture of the posterior portion of the spine that connects the facet joints and lamina with the anterior vertebral body at the level of the pedicle. This process is also known as a spondylolysis. It occurs in 5% of the general population but can be as high as 15% in certain athletes like gymnasts and football lineman due to the lumbar hyperextension. ...Read more

What is the basic meaning when MRI shows Bilateral L5 pars Interarticularis defects without subluxation? This incurred after a multiple car accident.

Spondylolysis: Spondylosysis, or pars interarticularis defect, is essentially a stress fracture of the narrow bridge of bone between vertebral body and the spinous process of the vertebrae. This is not an uncommon condition following repetitive trauma (seen also in gymnasts and football players). Subluxation occurs if the fracture separates from normal position and becomes displaced. ...Read more
