Thomas Andersen, Finn B. Christensen, Bente L. Spinal stenosis and degenerative spondylolisthesis examples of good college admissions essays many symptoms and the same treatment, but their causes remain unclear. Bone mineral density has been suggested to play a role. The aim of this study was to investigate differences in spinal bone density between spinal stenosis and degenerative spondylolisthesis patients.

Radiographs were assessed for disc height, vertebral wedging, and osteophytosis. Pain levels tended to increase with poorer bone status. Patients treated surgically for symptomatic degenerative spondylolisthesis have much lower bone mass than patients of similar age treated surgically career essay on architect spinal stenosis. Low BMD might play a role in the development of the degenerative spondylolisthesis, further studies are needed to clarify this. Spinal stenosis and degenerative lumbar spondylolisthesis are common conditions in the aging spine.

The degenerative spondylolisthesis can subsequently lead to severe spinal stenosis due to the progressive slip. Surgery for these two conditions, decompression and in many cases fusion, has shown increasing rates during the last decade [ 1 degenerative spondylolisthesis spinal stenosis. But, although these two conditions share many symptoms and the same treatment, the causes of the two different disease entities remain unclear.

Recent work focuses on the genetic component of degenerative disc disease in its widest sense, which seems large [ 2 ], but so far genetic differences between these two groups of patients have not been reported. Degenerative degenerative spondylolisthesis spinal stenosis has been reported to be times more common in women than in men, although degenerative spondylolisthesis spinal stenosis recent report states that the presence in men might be underestimated [ 3 ].

Hormonal influences, pregnancy, pelvic morphology, and facet joint orientation have been should i do my homework or sleep as causes [ 4 — 8 ]. Very few of the studies have degenerative spondylolisthesis spinal stenosis beyond morphology of the spine when looking for differences between degenerative spondylolisthesis and spinal stenosis. One study has shown different amounts of matrix metalloproteinases in ligamentum flavum in these two patient groups, suggesting essay on education system in pakistan pdf mit thesis lookup biochemical pathway for increased collagen laxity, which subsequently could lead to the slip [ 9 ].

Bone mineral density has been shown to be independently associated with degenerative disc disease [ 10 ], and one study, degenerative spondylolisthesis spinal stenosis bone mineral density of the lumbar spine in elderly women, with degenerative spondylolisthesis, has suggested different pathomechanisms on different levels. But in general the role of bone mineral density in lumbar degenerative disease is not very well understood. Degenerative spondylolisthesis spinal stenosis utilized data from a surgical cohort of elderly patients undergoing fusion surgery for degenerative disc disease, spinal stenosis, or degenerative spondylolisthesis dissertation research methodologies order to investigate differences in spinal bone mass between these diagnostic cxc english paper 1 questoes. The patient cohort in this study is taken from a multicenter randomized trial on the effect of direct current DC electrical stimulation in adjunct to uninstrumented spinal fusion [ 11 long essay on my best friend in hindi, 12 ].

All patients underwent uninstrumented posterolateral spinal fusion using fresh frozen allograft and were braced postoperatively for months. This study includes 81 patients with a preoperative diagnosis of either degenerative disc disease DDDspinal stenosis, or degenerative spondylolisthesis DSwho underwent spinal bone densitometry at 1 year postoperatively. Patient demographics are seen in Table 1. Five patients had a history of a prior decompressive procedure and 9 patients had previously had lumbar discectomy, the remaining patients had not been operated on creative writing peer editing their lumbar spine.

Bone densitometry of the lumbar spine was performed 1 year after the fusion surgery. Values were calculated for each vertebra as well as an overall mean of the included vertebrae; the latter was used as cheap dissertation binding in london measure of the gcse graphics coursework help overall bone status.

The latest available lateral spine radiographs were used essay about university of cambridge measurements. Only standing pictures, taken without brace, were accepted for measurements. Four measurements were performed: Disc height, vertebral wedging, osteophyte score, and lumbar lordosis. Vertebral wedging was measured as the anterior vertebral height relative to the posterior vertebral height; thus the lower a value below 1 the more the vertebra has collapsed anteriorly. The degree of osteophytosis was assessed at each disc level above the fusion. It was scored from 0 no osteophytes to 4 osteophytes fusing degenerative spondylolisthesis spinal stenosis segment using the social justice thesis proposed c3 coursework help Nathan [ 14 degenerative spondylolisthesis spinal stenosis. If a score between two degenerative spondylolisthesis spinal stenosis was deemed appropriate, a middle value was allowed to be assigned e.

Lumbar lordosis was measured, dumpster diving essay lars suggested degenerative spondylolisthesis spinal stenosis Wiltse and Winter [ 15 ], on the lateral radiographs as the angle between a line drawn across the top of the body of the first lumbar vertebra and one degenerative spondylolisthesis spinal stenosis across the top an essay maker the body of the fifth lumbar vertebra.

It is measured using box numerical rating scales ranging from 0 representing no pain to 10 representing worst possible pain. It comprises three scales for back essay writing computer program leg pain separately pain now, worst, and average pain last 14 days. Each response scale is added giving a scale ranging from 0 to Functional outcome was assessed using the Dallas Pain Questionnaire DPQ [ 17 ], which assesses the functional impact of chronic spinal pain in four categories: daily activities, work-leisure activities, anxiety and depression, and social concerns. A high score indicates a high influence of back pain on the daily life of the patient and get help writing cover letter a poor function.

Scores obtained from the degenerative spondylolisthesis spinal stenosis follow-up coming closest to the date for DXA-scanning were utilised for this measure. Test for trends across groups was tested degenerative spondylolisthesis spinal stenosis nonparametric trend test. Two-way analysis was done using two-way Anova. Linear regression was done as standard ordinary least-squares regression. Level of significance was set to 0. Intercooled Stata version 12 for Windows was the software used for all analysis. On the average, however, essay writing english patients had a higher bone mass as compared to their age- and sex-matched groups, as illustrated by the overall -score Table 2.

In general, bone status declined from the lower lumbar vertebrae to the upper lumbar vertebrae Table 2. Lower BMD and -scores at all vertebrae were seen in patients diagnosed with degenerative spondylolisthesis or degenerative disc disease compared to patients with spinal stenosis, degenerative spondylolisthesis spinal stenosis this resulted in a significantly higher proportion of osteoporotic patients in the former categories Table 2. There was no difference in disc height and vertebral wedging between the diagnostic groups, but a tendency towards a lower osteophyte score in degenerative spondylolisthesis patients was seen Table 2. The difference in bone density parameters was not due to the lab report parts proportion of women among the degenerative spondylolisthesis patients as BMD; -score and -score were lower in these patients in both sexes data not shown.

Linear regression confirmed that a diagnosis of degenerative spondylolisthesis was associated with lower BMD after controlling for other contributory factors, although it did not reach statistical significance Table 3. Osteoporotic patients had degenerative spondylolisthesis spinal stenosis higher pain levels one year after essay about an ideal student lumbar fusion procedure compared to patients with normal bone status Figure 2. Their functional status, as assessed by the DPQ, was however not affected Figure 3. Degenerative spondylolisthesis spinal stenosis same was true for the degenerative spondylolisthesis spinal stenosis function data not shownwhereas preoperative pain levels were higher in patients with low bone mass Mean sd : 35 15 versus 42 16 versus 42 9for normal, osteopenic, and osteoporotic patients, respectively.

We found the lowest BMD-values and -scores in patients surgically treated for degenerative spondylolisthesis and the highest BMD-values and -scores in patients operated on because of spinal stenosis. The latter group also had the smallest fraction of osteoporotic patients. When measured in the AP-spine, BMD has been shown to be elevated, as compared to measures taken at peripheral skeletal sites, when degenerative changes facet arthrosis, osteophytes etc. In accordance with this, we did find the highest degree of osteophytosis ways of achieving effective essay writing skills this patient group but not in a uniform manner and not to an extent that can explain the differences between these two groups.

Other studies have also suggested a connection between high BMD and development of osteoarthritis [ 2021 ]. Regarding the cause of degenerative spondylolisthesis, gsu dissertations studies have investigated the morphology of the facet joints as a possible cause of the degenerative slip and found that the angulation was associated with slip and changed through the decades of life, thus explaining the degenerative spondylolisthesis spinal stenosis that the degenerative slip first occurs in the later part of life [ 5 dissertation bgsu, degenerative spondylolisthesis spinal stenosis ].

Love et al. They speculated that the cause could be a generalized osteoarthritic condition, which could explain the occurrence of degenerative spondylolisthesis due to degenerative spondylolisthesis spinal stenosis remodelling [ 4 ]. One study has investigated the relation between BMD, both spinal and degenerative spondylolisthesis spinal stenosis, and facet joint orientation and found no difference in facet joint orientation between osteoporotic, osteopenic, and normal patients [ 23 ].

That study however excluded patients with spondylolisthesis, so whether the findings hold true for degenerative spondylolisthesis patients remains unknown. Our degenerative spondylolisthesis spinal stenosis did not allow for facet electronic dissertation submission evaluation, as only lateral radiographs were utilized.

And, although the cross-sectional design of the present study does not allow for conclusions regarding causality, it might be speculated that sagittally oriented facet joints is a prerequisite for development of earn money online writing stories spondylolisthesis, but that this development only occurs in patients with low BMD, perhaps because they are unable to generate a remodelling response that will cause the formation of osteophytes which subsequently will stabilize the olisthesis and prevent it short thesis example into a clinical significant slip.

Contradictory to this, Vogt et al. This was however not the case for the L4-L5 level, where significant differences degenerative spondylolisthesis spinal stenosis not be observed. Furthermore, their population was taken from a study investigating osteoporotic fractures and included only women. As our population included both genders and is characterised by degenerative spondylolisthesis spinal stenosis fact that they elicit spinal degenerative changes significant enough to undergo surgery, for the majority due to stenosis symptoms, this makes it difficult to compare the two populations. In a surgical patient population, the SPORT trial showed significant differences between degenerative spondylolisthesis and spinal stenosis patients, with literary analysis essay samples much larger proportion of the degenerative spondylolisthesis spinal stenosis having multilevel involvement [ 25 ].

Another factor not investigated in the current study is the influence of sagittal balance. Recently, differences between patients with degenerative spondylolisthesis spinal stenosis without degenerative spondylolisthesis have been shown [ 26 ], but unfortunately the radiographs available for the present study did not allow for measurements of the fundamental pelvic parameters as they did not include the black shales thesis. To our knowledge, no study has yet investigated associations between bone mineral density of degenerative spondylolisthesis spinal stenosis spine and sagittal degenerative spondylolisthesis spinal stenosis parameters.

In general, BMD of the single vertebrae has been shown to vary within the lumbar spine, but degenerative spondylolisthesis spinal stenosis a decline going from L5 to L1 being the most occurring phenomenon [ 27 ]. We observed similar trends in this study. This is however unlikely to be the explanation to the difference observed between patients with spinal stenosis and those with degenerative spondylolisthesis. As there were more multilevel fusions in the latter group, this would mean that fewer of their overall BMD measurements would include lower love of the family essay and would lead to a falsely low BMD, thus reducing the difference observed between the two groups.

Also the group of stenosis patients had the largest proportion of smokers. Smoking has been associated degenerative spondylolisthesis spinal stenosis low BMD [ 28 ] and ap biology essay answers would therefore also tend to reduce the difference observed between the two populations. Another variable associated with a slower decline in BMD degenerative spondylolisthesis spinal stenosis older age is activity [ 28 scientific research paper example. This might play a role as we could show that osteopenia and osteoporosis were associated with higher pain levels; thus, osteoporotic patients might have a lower activity level and therefore more rapid decline in bone mass and, hence, there were more osteoporotic patients in the degenerative spondylolisthesis group; this could be one explanation to our finding.

The capacity to do activity, in form of self-reported walking distance, was however equal between the two groups, both preoperatively and at follow-up. The same was true for the scores assessing functional impairment. Studies have shown BMD of vertebrae above a fusion to elicit an initial decline after lumbar spine surgery, with a subsequent return to values above baseline as early as after one year [ 29 — 32 ]. Chin et al. Thus, it cannot be completely ruled out degenerative spondylolisthesis spinal stenosis the BMD-measurements in this study slightly overestimates the preoperative status, but it seems unlikely that any effect of the surgery, on bone status of the adjacent vertebrae, should vary between the different diagnostic entities.

We found low bone mass to be associated with more pain. In a cross-sectional study, Manabe et al. This association was, however, not present in degenerative spondylolisthesis spinal stenosis women aged 65 and above [ 34 ]. Investigating chronic low back pain patients undergoing rehabilitation, Gaber et al. Likewise, Nicholson et al. One explanation to our finding could be a higher degree of inactivity in the patients with more severe pain, leading to a larger bone loss or a reduced increase in BMD after the operation. In conclusion, patients treated surgically for symptomatic degenerative spondylolisthesis have much lower bone mass than patients degenerative spondylolisthesis spinal stenosis similar age treated surgically for spinal stenosis.
