lumbarization

lumbarization

 [lum″bahr-ĭ-za´shun]
nonfusion of the first and second segments of the sacrum so that there is one additional articulated vertebra, the sacrum consisting of only four segments.

lum·bar·i·za·tion

(lŭm'bar-i-zā'shŭn),
A congenital anomaly of the lumbosacral junction characterized by development of the first sacral vertebra as a lumbar vertebra, resulting in six lumbar vertebrae instead of five.

Patient discussion about lumbarization

Q. I have a low back pain that radiates to my leg when i pick up stuff. Is it a disc herniation? I am a 43 years old bank teller. During the past 5 months I've suffered from a low back pain. The pain is not very strong, but it gets much worse while doing physical activity. When i walk or lift heavy things the pain is even stronger, and it radiates to my left leg. Can it be signs for disc herniation?

A. It's possible that you have a nerve impingement from a disc herniation, but not necessarily so. What you need to know is that even if you have a herniated disc, the question is what would the recommended treatment be?
90% or more of herniated discs resolve without surgical treatment within 6 months. MRI imaging is generally only indicated if one is considering surgery; in other words, your pain and neurological status is such that surgery is clinically indicated. Then, an MRI may be helpful for the surgeon. If surgery is not indicated based on clinical/symptoms, then it probably is unwise to get an MRI. They often show abnormalities that are simply 'red herrings' and often prompt people to proceed with surgery that really is not needed. Beware!

Q. What is the best way to strengthen the low back muscles? After having a low back strain I've been told I need to work better on the lower back muscles as too much stress is on them and they're not strong enough to handle it...any suggestions?

A. i have lower back strains but that is because i run. my back muscles are stronger then abdomen muscles and that causes an imbalance. the best way is starting swimming. the best sport for the body... and a thing to do for now (not instead of swimming just for the time being until you'll develop muscles)- lay on your stomach on a bed with your head sticking out for about 10-15 minutes every now and then. this will lengthen your back muscle and prevent strains for now.

Q. I have developed a low back pain from some heavy lifting over the weekend. What tests in the doctor's office can I expect to confirm this. And what should the treatment be. I suspect a sacriliac strain.

A. More than likely you have developed some muscle strain. If the pain goes away on it's own after rest for a few days, I suspect that's all it is. If the pain persists and starts to radiate down your buttocks and leg(s), then you should see an orthopedic surgeon for more extensive tests. Good luck to you.

(1-3) The spectrum of these transitions include: (a) accessory L5-S1 articulations between the transverse elements, (b) unilateral/bilateral L5-S1 fusions (sacralization), or (c) partial/complete separation between S1-S2 elements (lumbarization).
Samples with complete ossification of the growth plates and free from major structural damage were selected for measurements after identification of LSTV characteristics of accessory articulation on the ala of the sacrum, additional/partial segments (> 5 = sacralization) or less/partial sacral segments (< 5 = lumbarization).
A patient was not included in the study if any of the following were present: pregnancy, anatomical sacral abnormality (lumbarization or sacralization), known or suspected coagulopathy, systemic infection, any active injection site infection, or a history of allergy to TFESI injectates (e.g., contrast media, local anesthetics, or corticosteroids).
(13-15) Lumbosacral transitional vertebrae are congenital spinal anomalies defined as either sacralisation of the lowest lumbar segment or lumbarization of the most superior sacral segment of the spine.
Lumbarization of the first sacral vertebra refers to the segmentation and incorporation of this vertebra into the lumbar spine.
Lumbarization of first sacral vertebra: A case report.
It is worthy to mention that no cases of lumbar sacralization or sacral lumbarization or any transitional anomalies were identified that may influence the counting of the vertebras (these were ruled out using the initial scout view that serves for counting purposes).
Developmental defects occurring at the lumbosacral border results in sacralization of fifth lumbar vertebra or lumbarization of first sacral vertebra [2-4] and developmental defects occurring at the sacrococcygeal border results in sacralization of first coccygeal vertebra.
Lumbosacral transitional vertebrae (LSTV) are congenital anomalies of the lumbosacral region which includes lumbarization and sacralization [2,9] observed for the first time by Bertolotti.
[4] When the L5 vertebra is fused to the sacrum completely (Sacralization of L5), there are only four lumbar vertebrae, whereas when S1 is separated from the sacrum (Lumbarization of S1), there are six lumbar vertebrae, and many intermediate variations are reported.
In the current study sacrum with three pairs of sacral foramina is formed due to non-fusion of the first and second segments of the sacrum so that there is one additional articulating vertebra, the sacrum consisting of only four segments (lumbarization of first sacral vertebra).
(42) found that there was an increase frequency in those with low back pain in right-sided scoliosis, sacral lumbarization, lumbar lordosis, wedge vertebra, bilateral spondylolysis of L5 and/or a diameter of less than 12 mm in the sagittal plane.
