    We studied to determine whether the degenerative spondylolisthesis has rotary deformity in addition to forward displacement. We have made analysis of difference of rotary deformity between the 31 study groups of symptomatic degenerative spondylolisthesis and 31 control groups without any symptom, statistically. We also reviewed CT findings in 15 study groups. The mean rotary deformity in study groups was 6.1 degree(the standard deviation is 5.20), and the mean rotary deformity in control groups was 2.52 degree(the standard deviation is 2.16)(p < 0.01). The rotary deformity can be accompanied with degenerative spondylolisthesis. We may consider the rotary deformity as a cause of symptomatic degenerative spondylolisthesis in case that any other cause is not detected.

    CT evaluate the finding useful for differential diagnosis and associated abnormalities of isthmic spondylolisthesis and degenerative spondylolisthesis on CT. We reviewed retrospectively the CT images of 164 patients who were diagnosed spondylolisthesis. One hundred twelve patients had isthmic spondylolisthesis and 52 patients had degenerative spondylolisthesis. Isthmic spondylolisthesis most frequently occurred at L5. The degree of anterior displacement was grade I and II. The defect had a horizontal plane, an irregular surface, a sclerotic margin, and protruding hypertrophic bony spur in the spinal canal. The most frequently associated structural abnormality was a herniated nucleus pulposus at the upper level of the defect. Degenerative spondylolisthesis most frequently occurred at L4-5 and were grade I. The degenerative facet joint had a vertical plane, a hypertrophic bony spur, and a vacuum facet phenomenon. We frequently detected a pseudobulging disk. The most frequently associated structural abnormality was a herniated nucleus pulposus at the level of the displacement. In spondylolisthesis, the findings in CT were valuable for differential diagnosis of isthmic and degenerative types and the detection of associated symptomatic abnormalities.

    Full Text Available ABSTRACT Objectives: To determine the standard of treatment of degenerative lumbar spondylolisthesis in its different clinical presentations in UMAE Dr. Victorio de la Fuente Narváez. Methods: Six cases found in the literature were presented to 36 experts in spine surgery, along with treatment options, to thereby obtain a standard prescription for the treatment of degenerative lumbar spondylolisthesis. Analytical observational cross-sectional descriptive study. Results: It was found that the treatment of choice in cases of degenerative lumbar spondylolisthesis with axial symptoms is conservative. The surgical treatment of choice for both stable and unstable patients with radiculopathy and/or claudication is decompression + posterolateral graft + transpedicular instrumentation + discectomy (graft. Conclusions: We managed to define the degenerative lumbar spondylolisthesis treatment guidelines in our unit, which can serve as a basis for the development of a clinical practice guide.

    Several reports have examined the pathophysiology of degenerative spondylolisthesis. Very little work has however been devoted to the influence of spinal balance in the sagittal plane in its pathogenesis. The purpose of this work was to present a descriptive analysis of pelvic and spinal sagittal balance in a cohort of seventy patients treated for degenerative spondylolisthesis and to compare findings with those established in a population of 250 volunteers. The goal was to deduct pathophysiological hypotheses and identify therapeutic implications. Seventy patients were included in this study. The following variables were noted: pelvic incidence and version, sacral slope, lumbar lordosis, thoracic kyphosis, T9 sagittal tilt and S1-S2 angle. These variables were measured on digitalized lateral views of the spine using a dedicated software (SpineView). Univariate analysis of the values obtained was performed to identify the variable distributions. Multivariate analysis was applied to study the relationships between these variables and to better define perturbations of spinal balance in the anteroposterior plane. The findings were compared with those obtained in a control population. One of the essential characteristics of the cohort of patients with degenerative spondylolisthesis was the presence of an exaggerated pelvic incidence (62.6 degrees versus 54.7 degrees in the control population). The most significant determinants of T9 sagittal tilt (which reflects sagittal balance) were: pelvic version, pelvic incidence, lumbar lordosis, and L4-S1 local lordosis. One-third of our patients presented posterior tilt due to exaggerated thoracic kyphosis. The high pelvic incidence, via hyperlordosis and increased pelvic version, could be one of the factors favoring degenerative disease of the spinal unit. This work enabled us to better describe sagittal balance in patients with degenerative spondylolisthesis and to propose hypotheses concerning the underlying mechanism of

    Full Text Available ABSTRACT Objective: To evaluate clinical and functional results of patients with lumbar degenerative spondylolisthesis treated with operatively or nonoperatively. Methods: Patients with degenerative spondylolisthesis treated either nonoperatively or operatively from 2004 to 2014 were selected from databases and a cross-sectional evaluation was performed. Outcome measures included back and leg visual analogue scales (VAS, Fischgrund criteria, Short Form-36 (SF-36 function score, and the modified Oswestry Disability Index (ODI. Results: 43 patients were evaluated: 20 with nonoperative treatment and 23 with operative treatment. Baseline characteristics were similar without significant differences between groups. Mean follow-up time was 43 months (range 10 - 72 for the nonoperative group and 36 months (range 6-80 for the operative group. Significant statistical difference in favor of operative group were found in back VAS (mean 4 versus 8, p = 0.000, leg VAS (mean 3 versus 6, p = 0.0015, SF-36 function score (mean 77 versus 35, p = 0.000, and ODI (mean 17 versus 46, p = 0.000. On the basis of the Fischgrund criteria, only 10 % of patients reported excellent or good health post nonoperative treatment versus 83% for those treated operatively (p = 0.000. Conclusion: In this cross-sectional study, we observed that symptomatic patients with degenerative spondylolisthesis who underwent operative treatment have superior clinical and functional scores compared to those that underwent nonoperative treatment.

    Lumbar interbody fusion is a widely accepted surgical procedure for patients with lumbar degenerative spondylolisthesis and lumbar spinal instability in the active age group. However, in elderly patients, it is often questionable whether it is truly necessary to construct rigid fixation for a short period of time. In recent years, we have been occasionally performing posterior dynamic stabilization in elderly patients with such lumbar disorders. Posterior dynamic stabilization was performed in 12 patients (6 women, 70.9 ± 5.6 years old at the time of operation) with lumbar degenerative spondylolisthesis in whom % slip was less than 20% or instability associated with lumbar disc herniation between March 2011 and March 2013. Movement occurs through the connector linked to the pedicle screw. In practice, 9 pairs of D connector system where the rod moves in the perpendicular direction alone and 8 pairs of Dynamic connector system where the connector linked to the pedicle screw rotates in the sagittal direction were installed. The observation period was 77-479 days, and the mean recovery rate of lumbar Japanese Orthopedic Association (JOA) score was 65.6 ± 20.8%. There was progression of slippage due to slight loosening in a case with lumbar degenerative spondylolisthesis, but this did not lead to exacerbation of the symptoms. Although follow-up was short, there were no symptomatic adjacent vertebral and disc disorders during this period. Posterior dynamic stabilization may diminish the development of adjacent vertebral or disc disorders due to lumbar interbody fusion, especially in elderly patients, and it may be a useful procedure that facilitates decompression and ensures a certain degree of spinal stabilization.

    Degenerative spondylolisthesis is a common presentation, yet the best surgical treatment continues to be a matter of debate. Interbody fusion is one of a number of options, but its exact role remains ill defined. The aim of this study was to provide a contemporary review of the literature to help determine the role, if any, of interbody fusion in the surgical treatment of degenerative spondylolisthesis. A systematic review of the literature since 2005 was performed. Details on study size, patient age, surgical treatments, levels of slip, patient reported outcome measures, radiographic outcomes, complications and selected utility measures were recorded. Studies that compared a cohort treated with interbody fusion and at least one other surgical intervention for comparison were included for review. Only studies examining the effect in degenerative spondylolisthesis were included. Two authors independently reviewed the manuscripts and extracted key data. Thirteen studies were included in the final analysis. A total of 565 underwent interbody fusion and 761 underwent other procedures including decompression alone, interspinous stabilisation and posterolateral fusion with or without instrumentation. Most studies were graded Level III evidence. Heterogeneous reporting of outcomes prevented formal statistical analysis. However, in general, studies reviewed concluded no significant clinical or radiographic difference in outcome between interbody fusion and other treatments. Two small studies suggested interbody fusion is a better option in cases of definite instability. Interbody fusion only provided outcomes as good as instrumented posterolateral fusion. However, most studies were Level III, and hence, we remain limited in defining the exact role of interbody fusion-cases with clear instability appear to be most appropriate. Future work should use agreed-upon common outcome measures and definitions.

    About one third of lumbar synovial cysts are associated with degenerative spondylolisthesis. Segmental instability is thought to contribute to the pathogenesis and recurrence of synovial cysts and lumbar fusion has been advocated as a treatment of choice in the presence of spondylolisthesis. In patients with spondylolisthesis, minimally invasive resection of lumbar synovial cysts, without fusion, could minimize surgically induced segmental instability while providing good pain relief. Clinical and radiological outcomes of lumbar synovial cyst patients with and without spondylolisthesis were retrospectively compared. Pain outcomes were assessed with modified Macnab criteria. Fifty-three patients (18 with grade 1 spondylolisthesis) underwent minimally invasive synovial cyst resection and all had either excellent or good pain outcome at ≤ 8 post- operative weeks (P = 1.000, n = 53). At > 8 post-operative weeks (mean (SD) follow-up of 200 (175) weeks), excellent or good outcomes were noted in 89% of patients without spondylolisthesis and in 75% of patients with spondylolisthesis (P = 0.425, n = 40). Four patients developed a new grade 1 spondylolisthesis at a mean follow-up of 2.6 ± 2.1 years. Nine patients were assessed for spondylolisthesis measurements at 1.2 ± 1.3 years of follow up and no significant difference was observed (5 ± 0 vs 5 ± 1 mm; P = 0.791). Two patients without spondylolisthesis and none of the patients with spondylolisthesis had a synovial cyst recurrence. Patients with concomitant lumbar degenerative spondylolisthesis and synovial cyst can have good short- and long-term clinical outcomes with minimally invasive surgery without fusion. Post-operative segmental instability does not appear to be significant in patients with spondylolisthesis. All patients included in this article signed an informed consent for the use of their medical information for research.

    We sought to evaluate the clinical and radiologic efficacy of stand-alone anterior lumbar interbody fusion (ALIF) for low grade degenerative spondylolisthesis, the favoured surgical management approach at our institution. The optimal approach for surgical management of spondylolisthesis remains contentious. We performed a prospective analysis of all consecutive patients with low grade lumbar spondylolisthesis who underwent ALIF between 2009 and 2013 by a single surgeon (n=27). The mean age was 64.9 years with a male to female ratio of 14:13. There were 32 levels operated and the average preoperative spondylolisthesis was 14.8%, which reduced to 6.4% postoperatively and 9.4% at the latest follow-up (p=0001). Postoperative disc height was increased to 175% of preoperative values and was statistically significant (plumbar degenerative spondylolisthesis. Future studies should include adequately powered, prospective, multicentre registry studies with long term follow-up to allow a better assessment of the relative benefits and risks.

    OBJECT A range of surgical options exists for the treatment of degenerative lumbar spondylolisthesis (DLS). The chosen technique inherently depends on the stability of the DLS. Despite a substantial body of literature dedicated to the outcome analysis of numerous DLS procedures, no consensus has been reached on defining or classifying the disorder with respect to stability or the role that instability should play in a treatment algorithm. The purpose of this study was to define grades of stability and to develop a guide for deciding on the optimal approach in surgically managing patients with DLS. METHODS The authors conducted a qualitative systematic review of clinical or biomechanical analyses evaluating the stability of and surgical outcomes for DLS for the period from 1990 to 2013. Research focused on nondegenerative forms of spondylolisthesis or spinal stenosis without associated DLS was excluded. The primary extracted results were clinical and radiographic parameters indicative of DLS instability. RESULTS The following preoperative parameters are predictors of stability in DLS: restabilization signs (disc height loss, osteophyte formation, vertebral endplate sclerosis, and ligament ossification), no disc angle change or less than 3 mm of translation on dynamic radiographs, and the absence of low-back pain. The validity and magnitude of each parameter's contribution can only be determined through appropriately powered prospective evaluation in the future. Identifying these parameters has allowed for the creation of a preliminary DLS instability classification (DSIC) scheme based on the preoperative assessment of DLS stability. CONCLUSIONS Spinal stability is an important factor to consider in the evaluation and treatment of patients with DLS. Qualitative assessment of the best available evidence revealed clinical and radiographic parameters for the creation of the DSIC, a decision aid to help surgeons develop a method of preoperative evaluation to better

    We tried to assess the value of posterior epidural fat for distinguishing isthmic spondylolisthesis from degenerative lumbar spondylolisthesis on midline sagittal MR images. The midline sagittal MR images of the lumbar spines were retrospectively studied for 50 patients without spondylolisthesis, for 78 patients with isthmic spondylolisthesis and for 43 patients with degenerative spondylolisthesis. The anteroposterior diameter of the posterior epidural fat (ADEF) was measured at each intervertebral disc level by two radiologists and these values were then compared between each group. To normalize for difference of body size, the posterior epidural fat ratio (PEFR) at each level of spondylolisthesis and at L1-2 were also determined for each level of spondylolisthesis, and the PERF was compared between each group. Statistical analysis was performed by the chi-square method. For the patients with isthmic spondylolisthesis, the ADEFs at the spinal levels with spondylolisthesis were significantly greater than those ADEFs in the control group that were measured at the corresponding disc levels (p<0.05). For the patients with degenerative spondylolisthesis, the ADEFs at the spinal level with spondylolisthesis were significantly less than the ADEFs in the control group that were measured at the corresponding disc levels (p<0.05). The PEFRs obtained at L4-5 were 1.37{+-}0.12 for the control group, 2.61{+-}1.31 for the patients with isthmic spondylolisthesis, and 0.60{+-}0.05 for the patients with degenerative spondylolisthesis. The PEFRs obtained at L5-S1 were 2.25{+-}1.32 for the control group, 3.47{+-}1.69 for the patients with isthmic spondylolisthesis and 1.65{+-}0.18 for the patients with degenerative spondylolisthesis. At both levels, the PEFRs were greatest for the isthmic spondylolisthesis group and smallest for the degenerative spondylolisthesis group, and all the differences were statistically significant.

    Degenerative spondylolisthesis is common in adults. No consensus is available about the analysis or surgical treatment of degenerative spondylolisthesis. In 2013, the French Society for Spine Surgery (Societe francaise de chirurgie du rachis) held a round table discussion to develop a classification system and assess the outcomes of the main surgical treatments. A multicentre study was conducted in nine centres located throughout France and Luxembourg. We established a database on a prospective cohort of 260 patients included between July 2011 and July 2012 and a retrospective cohort of 410 patients included in personal databases between 2009 and 2013. For patients in the prospective cohort clinical assessments were performed before and after surgery using the self-administered functional impact questionnaire AQS, SF12, and Oswestry Disability Index (ODI). Type of treatment and complications were recorded. Antero-posterior and lateral full-length radiographs were used to measure lumbar lordosis (LL), segmental lordosis (SL), pelvic incidence (PI), pelvic tilt (PT), sagittal vertical axis (SVA), and percentage of vertebral slippage. Mean follow-up was 10 months. We started a randomised clinical trial comparing posterior fusion of degenerative spondylolisthesis with versus without an inter-body cage. 60 patients were included, 30 underwent 180° fusion and 30 underwent 360° fusion using an inter-body cage implanted via a transforaminal approach. We evaluated the quality of neural decompression achieved by minimally invasive fusion technique. In a subgroup of 24 patients computed tomography (CT) was performed before and after the procedure and then compared. Mean age was 67 years and 73% of degenerative spondylolisthesis were located at L4-L5 level. The many surgical procedures performed in the prospective cohort were posterior fusion (39%), posterior fusion combined with inter-body fusion (36%), dynamic stabilization (15%), anterior lumbar fusion (8%), and postero

    The purpose of this article is to evaluate radiographically degenerative spondylolisthesis of the lumbar spine, with the main focus on the configuration of posterior elements. A comparative study between 49 cases of degenerative spondylolisthesis and 99 cases of other lumbar disorders was performed, using 13 radiographical parameters. The results clearly indicate the posterior elements of degenerative spondylolisthesis shifted horizontally and sagittally to allow slipping. This was due to the weak bony hook mechanism. Furthermore, almost all facet joints were morphologically classified as sagittal or intermediate type. Another meaningful difference was the alignment of the lumbar spine which showed an increase in both lordosis and lumbosacral angle. On the other hand, the level of Jacoby's line was almost the same in both groups. These characteristic configurations could be the cause of listhesis, although further study should be carried out to elucidate whether they are present at the non-listhetic stage. (author).

    Abstract The purpose of our study is to evaluate sagittal parameters in 2-level lumbar degenerative spondylolisthesis (DS) (TLDS). A total of 15 patients with TLDS, 40 patients with single-level DS (SLDS), and 30 normal volunteers as control were included in our study. All subjects performed on full spine X-ray. Two categorized data were analyzed: patient characteristics—age, sex, body mass index, radiographic parameters-pelvic incidence (PI), pelvic tilt (PT), lumbar lordosis (LL), sacral slope (SS), PI–LL, Cobb between the fifth thoracic vertebral and 12th thoracic vertebral (T5–T12), sagittal vertical axis (SVA) Cobb angle of spondylolisthesis level (CSL), ratio of PT to SS (PT/SS), CSL/LL, variation trend of SS over PI, and LL over PI. The PI (73.1° vs 52.9°), SS (50.8° vs 32.2°), LL (53.1° vs 46.9°), SVA (66.1 vs 22.0 mm), PI–LL (20.0° vs 6.0°), and CSL (23.6° vs 20.0°) in TLDS were significantly larger than these in SLDS. The PI (73.1° vs 40.6°), PT (22.3° vs 17.1°), SS (50.8° vs 23.5°), LL (53.1° vs 32.5°), PI–LL (20.0° vs 8.1°), and SVA (66.1 vs 17.0 mm) in TLDS were significantly larger than those in the normal group (NG). The PI (52.9° vs 40.6°), PT (21.0° vs 17.1°), SS (32.2° vs 23.5°), LL (46.9° vs 32.5°), and SVA (22.0 vs 17.0 mm) in SLDS were significantly higher than those in NG. However, PT/SS (44.0%), LL over PI (y = 0.39x + 24.25), SS over PI (y = 10.79 + 0.55x) were lower in TLDS than these in SLDS (63.8%, y = 0.41x + 25, y = 0.65x − 2.09, respectively), and the similar tend between SLDS and NG (74.0%, y = 0.49x + 13.09, y = 0.67x − 3.9, respectively). Our results showed that 2-level lumbar DS, which was caused by multiple-factors, has a severe sagittal imbalance, but single-level has not any. When we plan for surgical selection for 2-level lumbar DS, global sagittal balance must be considered. PMID:27977581

    In a review of 42 cases of degenerative arthritis of the cervical spine and 22 cases of cervical spine trauma with an observed anterior slip-page (spondylolisthesis) or posterior slippage (retrolisthesis) of the vertebral bodies of 2 mm or more, characteristic features were observed which allowed distinction between degenerative and traumatic slippage of the cervical spine. In degenerative slippage the shape of the articular facets and width of the facet joint space may remain normal; however, in most cases the articular facets become 'ground-down' with narrowing of the facet joint space and the articular facets themselves becoming thinned or ribbon-like. In traumatic slippage the articular facets will either be normally shaped or fractured and the facet joint space will be abnormally widened. Plain radiographs will usually allow this distinction to be made; however, in difficult cases polytomography may be required.

    OBJECT Decompression without fusion for degenerative lumbar stenosis is an effective treatment for both the pain and disability of neurogenic claudication. Iatrogenic instability following decompression may require further intervention to stabilize the spine. The authors review the incidence of postsurgical instability following lumbar decompression, and assess the impact of surgical technique as well as study design on the incidence of instability. METHODS A comprehensive literature search was performed to identify surgical cohorts of patients with degenerative lumbar stenosis, with and without preexisting spondylolisthesis, who were treated with laminectomy or minimally invasive decompression without fusion. Data on patient characteristics, surgical indications and techniques, clinical and radiographic outcomes, and reoperation rates were collected and analyzed. RESULTS A systematic review of 24 studies involving 2496 patients was performed, assessing both open laminectomy and minimally invasive bilateral canal enlargement. Postoperative pain and functional outcomes were similar across the various studies, and postoperative radiographie instability was seen in 5.5% of patients. Instability was seen more frequently in patients with preexisting spondylolisthesis (12.6%) and in those treated with open laminectomy (12%). Reoperation for instability was required in 1.8% of all patients, and was higher for patients with preoperative spondylolisthesis (9.3%) and for those treated with open laminectomy (4.1%). CONCLUSIONS Instability following lumbar decompression is a common occurrence. This is particularly true if decompression alone is selected as a surgical approach in patients with established spondylolisthesis. This complication may occur less commonly with the use of minimally invasive techniques; however, larger prospective cohort studies are necessary to more thoroughly explore these findings.

    Full Text Available Background: Lumbar degenerative spondylolisthesis (LDS is a degenerative slippage of the lumbar vertebrae. We aimed to evaluate the surgical outcome of degenerative spondylolisthesis with neural decompression, pedicular screw fixation, reduction, and posterolateral fusion. Methods: This before-after study was carried out on 45 patients (37 female and 8 male with LDS operated from August 2008 to January 2011. The patients’ pain and disability were assessed by visual analogue scale (VAS and Oswestry disability index (ODI questionnaire. In surgery, we applied distraction force to facilitate slip reduction. All the intra- and postoperative complications were recorded. The paired t-test and Pearson correlation coefficient were used for statistical analysis. Results: The mean age of patients and mean follow-up period were 58.3±3.5 years and 31.2±4.8 months, respectively. The mean slip correction rate was 52.2% with a mean correction loss of 4.8%. Preoperative VAS and ODI improved from 8.8 and 71.6 to postoperative 2.1 and 28.7, respectively. Clinical improvement was more prominent in more reduced patients, but Pearson coefficient could not find a significant correlation. Conclusion: Although spinal decompression with fusion and posterior instrumentation in surgical treatment of the patients with LDS result in satisfactory outcome, vertebral reduction cannot significantly enhance the clinical improvement.

    Full Text Available "nBackground: Degenerative spondylolisthesis is a common disease of the lumbar spine especially in older ones. The disease represents a challenge to the treating physician. At present, for those patients that deteriorate clinically, there are many proposed algorithms for the surgical treatment. This before and after study was undertaken to assess the surgical results of decompression and instrumented posterolateral fusion in these patients. "nMethods: The study population consisted of 23 patients who had undergone no prior surgery for degenerative spondylolisthesis on the lumbar spine. These patients were treated by decompression, bilateral posterolateral fusion, and segmental (pedicle screw instrumentation with mean follow-up of 29 months (range, 13-73 months. Finally, The clinical results were evaluated for all patients by means of an Oswestry Disability Index (ODI version 2.1, the Henderson's functional capacity, and persistence of leg symptoms, low back pain or claudication. Mann-Whitney and Chi-Square tests were used to assess the average values and comparison, respectively. "nResults: Henderson's functional capacity at the last visit session was excellent in 14 (60.9%, good in 7 (30.4%, fair in 2 (8.7% cases. ODI decreased from 72.2% (50-88% preoperatively to 14.4% (0-54% at the latest follow-up visit. A history of leg pain or claudication was correlated significantly with the amount of decline in ODI score and Henderson's functional capacity (p<0.05. "nConclusion: In spite of limited number of our patients, decompressive surgery plus instrumented posterolateral fusion is a safe, reliable, and satisfactory procedure for treating degenerative lumbar spondylolisthesis. This procedure may be done when conservative treatment was failed and psychological problems can be ruled out.

    Adult scoliosis is a complex three-dimensional rotational deformity of the spine, resulting from the progressive degeneration of the vertebral elements in middle age, in a previously straight spine; a Cobb angle greater than 10° in the coronal plane, which also alters the sagittal and axial planes. It originates an asymmetrical degenerative disc and facet joint, creating asymmetrical loads and subsequently deformity. The main symptom is axial, radicular pain and neurological deficit. Conservative treatment includes drugs and physical therapy. The epidural injections and facet for selectively blocking nerve roots improves short-term pain. Surgical treatment is reserved for patients with intractable pain, radiculopathy and/ or neurological deficits. There is no consensus for surgical indications, however, it must have a clear understanding of the symptoms and clinical signs. The goal of surgery is to decompress neural elements with restoration, modification of the three-dimensional shape deformity and stabilize the coronal and sagittal balance.

    Full Text Available ABSTRACT OBJECTIVE: To correlate spinopelvic balance with the development of degenerative spondylolisthesis and disk herniation. METHODS: This was a descriptive retrospective study that evaluated 60 patients in this hospital, 30 patients with degenerative spondylolisthesis at the L4-L5 level and 30 with herniated disk at the L4-L5 level, all of whom underwent Surgical treatment. RESULTS: Patients with lumbar disk herniation at L4-L5 level had a mean tilt of 8.06, mean slope of 36.93, and mean PI of 45. In patients with degenerative spondylolisthesis at the L4-L5 level, a mean tilt of 22.1, mean slope of 38.3, and mean PI of 61.4 were observed. CONCLUSION: This article reinforces the finding that the high mean tilt and PI are related to the onset of degenerative spondylolisthesis, and also concluded that the same angles, when low, increase the risk for disk herniation.

    Full Text Available Abstract Background Comparatively little is known about the relation between the sagittal vertical axis and clinical outcome in cases of degenerative lumbar spondylolisthesis. The objective of this study was to determine whether lumbar sagittal balance affects clinical outcomes after posterior interbody fusion. This series suggests that consideration of sagittal balance during posterior interbody fusion for degenerative spondylolisthesis can yield high levels of patient satisfaction and restore spinal balance Methods A retrospective study of clinical outcomes and a radiological review was performed on 18 patients with one or two level degenerative spondylolisthesis. Patients were divided into two groups: the patients without improvement in pelvic tilt, postoperatively (Group A; n = 10 and the patients with improvement in pelvic tilt postoperatively (Group B; n = 8. Pre- and postoperative clinical outcome surveys were administered to determine Visual Analogue Pain Scores (VAS and Oswestry disability index (ODI. In addition, we evaluated full spine radiographic films for pelvic tilt (PT, sacral slope (SS, pelvic incidence (PI, thoracic kyphosis (TK, lumbar lordosis (LL, sacrofemoral distance (SFD, and sacro C7 plumb line distance (SC7D Results All 18 patients underwent surgery principally for the relief of radicular leg pain and back pain. In groups A and B, mean preoperative VAS were 6.85 and 6.81, respectively, and these improved to 3.20 and 1.63 at last follow-up. Mean preoperative ODI were 43.2 and 50.4, respectively, and these improved to 23.6 and 18.9 at last follow-up. In spinopelvic parameters, no significant difference was found between preoperative and follow up variables except PT in Group A. However, significant difference was found between the preoperative and follows up values of PT, SS, TK, LL, and SFD/SC7D in Group B.

    Full Text Available Objective:To evaluate a method to reduce high degree spondylolisthesis in adults with monosegmental fixing preserving the adjacent level and the improvement of sagittal balance.Methods:A prospective study, with 12 adult patients with high degree spondylolisthesis (III and IV in adults who underwent surgery by the same team. We included 7 women and 5 men with a mean age of 37 years and lombosciatalgy that had no improvement with conservative treatment. The surgical technique used was total or partial reduction by Spondylolisthesis Reduction Instrument (SRI system, with instrumentation only in the affected level, thus sparing the adjacent level, associated with 360ofusion.Results:The L5-S1 level was involved in nine patients, L4-L5 in two, and VT-S1 in one patient. The isthmic type predominated in nine patients, followed by dysplastic type in two, and one iatrogenic spondylolisthesis. These patients were assessed by the Oswestry scale, which showed a preoperative average of 59% and postoperative average of 12.4% (P<0.05. A significant improvement in the average slip angle from 54.66% to 9.5% (35% to 0% was found. No major complications such as infection, neurological damage or material breaks were observed.Conclusion:The reduction of high degree listhesis instrumenting only the affected level produces good results, with good control of pain and functional improvement of patients. However, a larger follow-up is required to better evaluation.

    Many studies attest to the excellent results achieved using anterior lumbar interbody fusion (ALIF) for degenerative spondylolisthesis. The purpose of this report is to document a rare instance of L-4 vertebral body fracture following use of a stand-alone interbody fusion device for L3-4 ALIF. The patient, a 55-year-old man, had suffered intractable pain of the back, right buttock, and left leg for several weeks. Initial radiographs showed Grade I degenerative spondylolisthesis, with instability in the sagittal plane (upon 15° rotation) and stenosis of central and both lateral recesses at the L3-4 level. Anterior lumbar interbody fusion of the affected vertebrae was subsequently conducted using a stand-alone cage/plate system. Postoperatively, the severity of spondylolisthesis diminished, with resolution of symptoms. However, the patient returned 2 months later with both leg weakness and back pain. Plain radiographs and CT indicated device failure due to anterior fracture of the L-4 vertebral body, and the spondylolisthesis had recurred. At this point, bilateral facetectomies were performed, with reduction/fixation of L3-4 by pedicle screws. Again, degenerative spondylolisthesis improved postsurgically and symptoms eased, with eventual healing of the vertebral body fracture. This report documents a rare instance of L-4 vertebral body fracture following use of a stand-alone device for ALIF at L3-4, likely as a consequence of angular instability in degenerative spondylolisthesis. Under such conditions, additional pedicle screw fixation is advised.

    Study Design Level 4 retrospective review. Purpose To compare the radiographic and clinical outcomes between posterior lumbar interbody fusion (PLIF) and lateral lumbar interbody fusion (LLIF) with posterior segmental spinal instrumentation (SSI) for degenerative lumbar spondylolisthesis. Overview of Literature Both PLIF and LLIF have been performed for degenerative spondylolisthesis with good results, but no study has directly compared these two techniques so far. Methods The electronic medical and radiographic records of 78 matched patients were analyzed. In one group, 39 patients underwent PLIF with SSI at 41 levels (L3-4/L4-5), while in the other group, 39 patients underwent the LLIF procedure at 48 levels (L3-4/L4-5). Radiological outcomes such as restoration of disc height and neuroforaminal height, segmental lumbar lordosis, total lumbar lordosis, incidence of endplate fracture, and subsidence were measured. Perioperative parameters were also recorded in each group. Clinical outcome in both groups was assessed by the short form-12, Oswestry disability index and visual analogue scale scores. The average follow-up period was 16.1 months in the LLIF group and 21 months in the PLIF group. Results The restoration of disc height, foraminal height, and segmental lumbar lordosis was significantly better in the LLIF group (p<0.001). The duration of the operation was similar in both groups, but the average blood loss was significantly lower in the LLIF group (p<0.001). However, clinical outcome scores were similar in both groups. Conclusions Safe, effective interbody fusion can be achieved at multiple levels with neuromonitoring by the lateral approach. LLIF is a viable treatment option in patients with new onset symptoms due to degenerative spondylolisthesis who have had previous lumbar spine surgery, and it results in improved sagittal alignment and indirect foraminal decompression.

    A retrospective, observational study. The aim of this study was to determine the utilization of various treatment modalities in the management of degenerative spondylolisthesis within Medicare beneficiaries. Degenerative lumbar spondylolisthesis is a condition often identified in symptomatic low back pain. A variety of treatment algorithms including physical therapy and interventional techniques can be used to manage clinically significant degenerative spondylolisthesis. This study utilized the 5% national sample of Medicare carrier claims from 2000 through 2011. A cohort of beneficiaries with a new International Classification of Diseases 9th edition (ICD-9) diagnosis code for degenerative lumbar spondylolisthesis was identified. Current procedural terminology codes were used to identify the number of procedures performed each year by specialty on this cohort. A total of 95,647 individuals were included in the analysis. Average age at the time of initial diagnosis was 72.8 ± 9.8 years. Within this study cohort, spondylolisthesis was more prevalent in females (69%) than males and in Caucasians (88%) than other racial demographics. Over 50% of beneficiaries underwent at least one injection, approximately one-third (37%) participated in physical therapy, one in five (21%) underwent spinal surgery, and one-third (36%) did not utilize any of these interventions. Greater than half of all procedures (124,280/216,088) occurred within 2 years of diagnosis. The ratio of focal interventions (transforaminal and facet interventions) to less selective (interlaminar) procedures was greater for the specialty of Physical Medicine and Rehabilitation than for the specialties of Anesthesiology, Interventional Radiology, Neurosurgery, and Orthopedic Surgery. The majority of physical therapy was dedicated to passive treatment modalities and range of motion exercises rather than active strengthening modalities within this cohort. Interventional techniques and physical therapy are

    We evaluated MR imaging of spondylolytic spondylolisthesis, degenerative spondylolisthesis and retrolisthesis in 14, 9 and 20 patients respectively. Sagittal and axial spin echo and gradient echo images were obtained with 25-30 cm FOV and 5mm/0.5 mm thickness/gap by using spine surface coil. Sagittal images showed defects of pars interarticularis just inside of the pedicles of spines in all the cases of spondylolytic spondylolisthesis with relative variable signal intensity. Displaced vertebrae were commonly observed at L5 (8/14) in spondylolytic spondylolisthesis, at L4 (5/9) in generative spondylolisthesis and at variable locations in retrolisthesis. The mean length of displacement of vertebrae in spondylolytic spondylolisthesis was about 7 mm and less displacement was onserved in degenerative spondylolisthesis and retrolisthsis. Seven, four and six cases of pseudobulging of disk at displaced level were observed in cases of spondylolytic spondylolisthesis, degenerative spondylolisthesis and retrolisthesis respectively. Seven, five and 14 case of true disk lesions were onserved in case of spondylolytic spondylolisthesis, degenertive spondylolisthesis and retrolisthesis respectively. Grade II nerual foraminal stenoses (obliteration of one half epidural fat of neural foramen) were commonly (8/14) seen in spondylolytic spondylolisthesis, however the other two types showed less severe neural foraminal stenosis. In conclusion, MR images is a highly accurate method for the diagnosis and evaluation of spondylolisthesis and associated lesions of spine and disks.

    A randomised study of 2000 patients (1000 males, 1000 females) revealed two forms of the triangular hyperostosis of the ilium in female patients. The hyperostosis triangularis ilii, HTI, is also known as osteitis condensans. One form of HTI concerning women under the age of 50 is called the adult generative HTI, the other beyond the age of 50 senile degenerative HTI. These two forms are not evident in male patients. The 3.05% incidence of HTI in adults appeared to be higher than presumed till now. The sex incidence male/female of 1:1.6 diverges considerably from preceding investigations. Histomorphological studies of two autopsies of cases of senile degenerative HTI revealed no signs of inflammation. Statistical correlations of HTI with other chronic diseases of the pelvis and hip could doubtlessly and generally be established only for osteoarthrosis of the sacro-iliac joints in females beyond the age of 50 and in males as a matter of principle.

    The vacuum phenomenon within the intervertebral disc usually represents disc degeneration. There are no reports in the English literature that focus on the effect of an anterior vacuum disc on surgical outcome of same-segment spondylolisthesis. Patients with degenerative spondylolisthesis (DS) or isthmic spondylolisthesis (IS) who underwent a spinal surgery between January 2005 and December 2006 were reviewed. Patients who met certain criteria, including (1) only mono-segment spondylolisthesis, (2) gas air within the disc space of the spondylolisthesis segment on preoperative radiographs, (3) having received posterior decompression, posterior pedicle screw fixation, and posterolateral fusion, and (4) at least 12 months of follow-up radiographs available to define the posterolateral fusion rate, were enrolled into the study. Four radiographic parameters (disc height, translation, intradiscal angle, segmental angle) were assessed. Two-year postoperative radiographs were used to determine whether the posterolateral segment was fused or not. Clinical outcome and complications during the follow-up period were documented. Incidence of the disc vacuum phenomenon was significantly higher in the IS group than in the DS group (p vacuum phenomenon is not equal to anterior instability absolutely. Determination of stability or instability in a vacuum disc should be considered by a combination of dynamic radiographs. In the present study, vacuum discs in the DS group showed more instability and a higher posterolateral pseudoarthrosis rate.

    Retrospective analysis. The object is to assess the correlation between whole lumbar lordosis (LL) and the segmental angle (SA) after single-level anterior lumbar interbody fusion for degenerative lumbar spondylolisthesis. The restoration of the SA at lower lumbar spine is meaningful, considering it contributes approximately 60% of LL, and revision surgery due to flat back or adjacent segment pathology was necessary decades after the initial surgery. However, little is known about the change of whole lumbar curvature after single-level lower lumbar fusion surgery, especially for balanced spine. We included 41 consecutive patients (M:F=9:32; mean age, 59.8±9.3 y) with a single-level anterior lumbar interbody fusion surgery for low-grade degenerative spinal spondylolisthesis, with C7 plumb line of sagittal alignment was influenced by single SA. Therefore, obtaining adequate segmental lordosis is desirable considering the effect on the whole spine for a long time.

    The rapid increase of elderly population has resulted in increased prevalence of adult scoliosis. Adult scoliosis is divided into adult idiopathic scoliosis and adult degenerative scoliosis. These two types of scoliosis vary in patient age, curve pattern and clinical symptoms, which necessitate different surgical indications and options. Back pain and deformity are major indications for surgery in adult idiopathic scoliosis, whereas radiating pain to the legs due to foraminal stenosis is what...

    Objective To compare the clinical results in the surgical treatment of degenerative spondylolisthesis and isthmic spondylolisthesis, regarding the safety, curative effects and fusion rate at 2 years after the operation.Methods A retrospective study was performed on 72 adult patients with grade II-III spondylolisthesis who underwent posterior lumbar interbody fusion ( PLIF ) from January 2005 to June 2011. All the patients were divided into 2 groups based on the pathological changes of lumbar spondylolisthesis, including the degenerative spondylolisthesis group (n=48 ) and the isthmic spondylolisthesis group (n=24 ). According to the Meyerding grading system for spondylolisthesis, there were 48 cases of grade II in the degenerative spondylolisthesis group and 10 cases of grade II and 14 cases of grade III in the isthmic spondylolisthesis group. All the patients underwent decompression, reduction, pedicle screw ifxation and spinal fusion. The differences in the preoperative general data between the 2 groups were not statistically significant (P>0.05 ). The operation time, intraoperative blood loss, postoperative ambulation time, postoperative average length of stay and average age were compared between the 2 groups. The curative outcomes were evaluated based on the Visual Analogue Scale ( VAS ) and Japanese Orthopedic Association ( JOA ) assessment criteria for back pain at 1 day before the surgery and 1 month and 2 years after the surgery. The lumbar fusion was observed by the X-ray and 3-dimensional reconstruction of CT scan at 1 year after the surgery.Results The average age of the isthmic spondylolisthesis group was ( 48.6±6.9 ) years old, who was younger than ( 59.5±9.9 ) years old of the degenerative spondylolisthesis group. The intraoperative blood loss, postoperative ambulation time and postoperative average length of stay were ( 343.3±62.4 ) ml, 5.3±2.7d and ( 8.6±2.4 ) d in the degenerative spondylolisthesis group, which were all less than ( 383.8±50

    Prospective, multicenter, institutional review board approved study with randomized and observational study arms. The purpose of this study was to compare radiographic outcomes between minimally invasive transforaminal (MIS TLIF) or MIS lateral interbody fusion (XLIF) in the treatment of patients with low-grade degenerative spondylolisthesis with stenosis through 2-year postoperative. Few reports exist comparing different MIS approaches directly in the treatment of similar pathology, as most studies report differences between MIS and open procedures. A total of 55 patients undergoing surgical treatment for degenerative spondylolisthesis with spinal stenosis at one or two contiguous levels between L1 and L5 were enrolled. Twenty-nine patients were treated with XLIF and 26 patients were treated with MIS TLIF. Disc height was significantly improved from preoperative at all postoperative time points in both groups, though the XLIF group experienced less subsidence and resultant loss of disc height than the MIS TLIF group by 24-month postoperative (P = 0.002). Postoperative change in central canal area was statistically greater in the MIS TLIF compared with the XLIF group (43.1 mmvs. 4.1 mm, P = 0.028). At several postoperative time points, foraminal height and area on the ipsilateral side and foraminal height on the contralateral side to the approach were significantly increased postoperatively in the XLIF group, and the magnitude of ipsilateral height increase was greater than in the MIS TLIF cohort (P MIS TLIF levels were solidly bridged (P = 0.448). Different mechanisms of stenosis correction (direct vs. indirect) between the MIS TLIF and XLIF groups studied resulted in several significantly different radiographic characteristics. Despite these differences, both groups of patients experienced significant and maintained clinical improvements with high fusion rates at 2-year follow-up, suggesting that the mechanism of correction may not be critical and

    A prospective, multicenter, institutional review board (IRB) approved study with randomized and observational study arms. The purpose of this study was to compare clinical outcomes between minimally invasive transforaminal (MIS TLIF) and MIS lateral interbody fusion (XLIF) in the treatment of patients with low-grade degenerative spondylolisthesis with stenosis through two years postoperative. Few reports exist comparing different MIS approaches directly in the treatment of similar pathology, as most studies report differences between MIS and open procedures. A total of 55 patients undergoing surgical treatment for degenerative spondylolisthesis with spinal stenosis at one or two contiguous levels between L1 and L5 were enrolled. Twenty-nine patients were treated with XLIF and 26 patients were treated with MIS TLIF. Operative time and length of stay were similar between the XLIF and MIS TLIF groups (171 vs 186 minutes; two days for each group). Blood loss was significantly lower in the XLIF group, with 79% of XLIF cases and 27% of MIS TLIF cases resulting in MIS TLIF group (0%). One patient in the XLIF group had a new distal motor weakness and three patients in the XLIF group and two patients in the MIS TLIF group had new sensory changes postoperatively, all of which resolved by 12 months postoperative. Back and leg pain for both XLIF and MIS TLIF groups improved significantly from baseline to 24 months postoperative, with 73% improvement in the XLIF and 64% in the MIS TLIF group. Worst leg pain showed similar improvements through two years postoperative, with a 79% decrease seen in the XLIF group and 74% in the MIS TLIF group. Disability (ODI) improved 53% in the XLIF group and 57% in the MIS TLIF group. Despite different mechanisms of action (indirect vs direct decompression), mid-term clinical outcomes between XLIF and MIS TLIF were similar. These two-year results suggest that both XLIF and MIS TLIF are reasonable MIS approaches for the treatment of lumbar

    Full Text Available OBJECTIVE: Aim of this study is to assess and compare the outcomes of posterior lumbar interbody fusion (PLIF and posterolateral fusion (PLF in adult isthmic spondylosthesis. BACKGROUND: Posterolateral fusion has been considered the best method and widely been used for surgical treatment of adult spondylolisthesis.Superior results have subsequently been reported with interbody fusion with cages and posterior instrumentation MATERIALS AND METHODS: Thirty six patients with isthmic spondylolisthesis were operated. One group (20 patients had decompression and posterolateral fusion (PLF with a pedicle screw system; other group (16 patients was treated by decompression, posterior lumbar interbody fusion (PLIF and a Pedicle screw system. In both groups adequate decompression was done RESULTS: Seventy seven percent of the patients had a good result with (PLIF and 68 percent with posterolateral fusion (PLF. However there was no statistical difference in cases with low grade slipping, whereas the difference was significant for cases with high grade slipping. Fusion rate was 93% with (PLIF and 68% with (PLF, but without any significant incidence in the functional outcome. 78% has relief of sciatica and neurogenic claudication. CONCLUSION: Based on these findings we found that for high grade spondylolisthesis which requires reduction or if the disc space is still high posterior lumbar inter body fusion is preferable. For low grade spondylolisthesis or if the disc space is narrow posterolateral fusion is preferable. A successful result of fusion operation depends on adequate decompression which relieves radicular symptoms.

    背景:近年来,关节突关节形态在退变性腰椎滑脱症发病中所起的作用是讨论的焦点,但多集中于关节角及骨关节炎 CT 表现的研究。有研究表明椎旁肌横截面积的变化被认为可能是退行性腰椎滑脱的病理学诊断的重要标志,但既往的研究由于样本量偏小、研究对象的年龄较小以及测量等诸多问题限制了其结论的准确性。  目的:观察退变性腰椎滑脱两侧椎旁肌的MRI影像学变化。  方法:采用回顾性研究方法,选取退行性腰椎滑脱的患者80例作为腰椎滑脱组,选取健康者80例作为对照组。应用Image J软件测量两组MRI T2加权像上L 3-5椎体下终板水平两侧竖脊肌和腰大肌的横截面积,并计算相关数据的比值。  结果与结论:与对照组相比,腰椎滑脱组同侧并同水平椎旁肌的横截面积比值增高(P0.05)。结果说明,椎旁肌横截面积的变化可导致退行性腰椎滑脱,可考虑其作为退行性腰椎滑脱的诊断标准。%BACKGROUND:Recently, the effects of lumbar facet joint morphology on the onset of degenerative lumbar spondylolisthesis have been a discussion point. However, the discussion mainly concerned CT manifestations of joint angle and osteoarthritis. Studies have shown that the changes in cross-sectional area of paraspinal muscle were considered as the essential marker for the pathological diagnosis of degenerative lumbar spondylolisthesis. However, previous studies limited the accuracy of the conclusion due to smal sample size, young age, and measurement. OBJECTIVE:To observe changes in MRI images of bilateral paraspinal muscles after degenerative lumbar spondylolisthesis. METHODS:This study adopted the method of retrospective study, selected 80 cases of degenerative lumbar spondylolisthesis as lumbar spondylolisthesis group, and 80 healthy persons as control group.

    To determine if cantilever transforaminal lumbar interbody fusion (C-TLIF) using the crescent-shaped titanium interbody spacer (IBS) favors acquisition of segmental and lumbar lordosis even for degenerative spondylolisthesis (DS) on a long-term basis. We analyzed 23 consecutive patients who underwent C-TLIF with pedicle screw instrumentations fixed with compression for a single-level DS. Measurements on the lateral radiographs taken preoperatively, 2 weeks postoperatively and at final follow-up included disc angle (DA), segmental angle (SA), lumbar lordosis (LL), disc height (%DH) and slip rate (%slip). There was a good functional recovery with 100 % fusion rate at the mean follow-up of 62 months. Segmental lordosis (DA and SA) and %DH initially increased, but subsequently decreased with the subsidence of the interbody spacer, resulting in a significant increase (p = 0.046) only in SA from 13.2° ± 5.5° preoperatively to 14.7° ± 6.4° at the final follow-up. Changes of LL and %slip were more consistent without correction loss finally showing an increase of LL by 3.6° (p = 0.005) and a slip reduction by 6.7 % (p lordosis on a long-term basis, which would be of benefit in preventing hypolordosis-induced back pain and the adjacent level disc disease.

    Full Text Available : BACKGROUND: Low back pain (LBP is a common presenting complaint affecting mostly middle aged and older person and traditionally considered as ageing process, but now-a-days large number of younger people are also affected by this debilitating chronic disorder. The cause of early onset of degenerative spine disease is multifactorial, but genetical predisposition plays very important role. AIMS AND OBJECTIVE: To find out association between genetic predisposition and degenerative spine disease in adult patients and to assess the pattern of MRI findings of various degenerative diseases in lumbo-sacral spine. MATERIAL AND METHOD: The present cross-sectional study had been performed among 100 selected patients in 1yr period, who presented with chief complaint of chronic low back pain. After taking detailed clinical and professional history, MRI of lumbosacral spine had been performed. Total 100 patients were divided in two groups on the basis of genetical predisposition. Prevalence and spectrum of degenerative changes were compared between both groups. RESULTS: Hundred patients of 20 to 35-year age had been selected with mean age of 27yr. Out of 100 patients; 47 were male and 53 were female. The most common degenerative findings were desiccation of disc (95% followed by disc bulge, herniation, spinal canal stenosis, ligamentum flavum hypertrophy, facet joint hypertrophy and modic changes. L4-L5 and L5- S1 were the most commonly involved spinal levels for any degenerative pathology. CONCLUSION: Good association is seen between early onset of degenerative spine disease and genetical predisposition in patients who have history of similar type degenerative spine disease in one or more first degree relatives in comparison to those patients who do not have any genetical predisposition. So it can be concluded that heredity play important role in early onset of degenerative spine disease in adults.

  17. Peritalar destabilisation syndrome (adult flatfoot with degenerative glenopathy).

    Science.gov (United States)

    Pisani, Giacomo

    2010-12-01

    In cases of adult acquired flatfoot associated with peritalar destabilisation, special reference is made to the plantar calcaneo-navicular (spring) ligament's degenerative disease (degenerative glenopathy) and to the presence of the accessory navicular bone as a possible pathogenic cause. Peritalar destabilization syndrome is proposed for the articular (subtalar and talo-navicular joints) or tendinosis (tibialis posterior tendon) separately or in association with degenerative glenopathy of the coxa pedis. In degenerative glenopathy surgical reconstruction of the glenoid also makes use of a posterior tibial split to create a new tibial-navicular ligament. The concept of pronatory syndrome deemed as the root the pathological subtalar pronation, which is an entirely secondary factor in peritalar destabilisation, must be questioned. We must keep in mind that subtalar pronation and supination are respectively subsequent to opening and closing of the coxa pedis (talo-calcaneo-navicular joint) kinetic chain.

    To assess the spinal canal and neural foraminal stenosis associated with spondylolisthesis on MR imaging. We retrospectively analysed MR findings of 63 cases of spondylolisthesis(degenerative type: 23 cases, isthmic type: 40 cases) regarding the type and grade of spondylolisthesis, presence or absence of associated spinal canal stenosis, and the severity of associated neural foraminal stenosis. Central canal stenosis were more frequent in degenerative type(91%) than isthmic type(33%), and more frequent in grade II spondylolisthesis of degenerative type(100%) and isthmic type(89%) than in grade I spondylolisthesis of degenerative type(45%) and isthmic type(20%). There was positive correlation between the severity of neural foraminal stenosis and the grade of spondylolisthesis, whereas there was no significant difference between degenerative and isthmic types. Degenerative spondylolisthesis were frequently associated with central canal stenosis more than isthmic type. When the grade of spondylolisthesis was higher, it was more frequently associated with central canal stenosis and severe neural foraminal stenosis.

    OBJECTIVE Several biomechanical studies have demonstrated the favorable mechanical properties of the cortical bone trajectory (CBT) screw. However, no reports have examined surgical outcomes of posterior lumbar interbody fusion (PLIF) with CBT screw fixation for degenerative spondylolisthesis (DS) compared with those after PLIF using traditional pedicle screw (PS) fixation. The purposes of this study were thus to elucidate surgical outcomes after PLIF with CBT screw fixation for DS and to compare these results with those after PLIF using traditional PS fixation. METHODS Ninety-five consecutive patients underwent PLIF with CBT screw fixation for DS (CBT group; mean followup 35 months). A historical control group consisted of 82 consecutive patients who underwent PLIF with traditional PS fixation (PS group; mean follow-up 40 months). Clinical status was assessed using the Japanese Orthopaedic Association (JOA) scale score. Fusion status was assessed by dynamic plain radiographs and CT. The need for additional surgery and surgery-related complications was also evaluated. RESULTS The mean JOA score improved significantly from 13.7 points before surgery to 23.3 points at the latest follow-up in the CBT group (mean recovery rate 64.4%), compared with 14.4 points preoperatively to 22.7 points at final follow-up in the PS group (mean recovery rate 55.8%; p fusion was achieved in 84 patients from the CBT group (88.4%) and in 79 patients from the PS group (96.3%, p > 0.05). Symptomatic adjacent-segment disease developed in 3 patients from the CBT group (3.2%) compared with 9 patients from the PS group (11.0%, p fusion rate tended to be lower in the CBT group than in the PS group, although the difference was not statistically significant between the 2 groups.

    Previous studies have shown that axial loading during MRI significantly reduces the size of the dural sac compared with conventional MRI in patients with degenerative lumbar disease. In our previous study, axial-loaded MRI showed a significantly larger degree of olisthesis than conventional MRI in patients with degenerative spondylolisthesis (DS). Furthermore, the degree of olisthesis on axial-loaded MRI correlated more strongly with that observed on X-ray in the upright position. However, no study has investigated whether or not the increase in the degree of olisthesis during axial loading correlates with the reduction in the dural sac size and affects the severity of clinical symptoms in patients with DS. To determine whether or not the increase in the degree of olisthesis correlates with the reduction of the dural sac cross-sectional area (DCSA) detected on axial-loaded MRI and worsens the severity of clinical symptoms in patients with DS. Imaging cohort study. A total of 41 consecutive patients with DS were prospectively evaluated in this study. The degree of olisthesis, the DCSA, Pearson's correlation coefficient, and the severity of clinical symptoms. The differences in the degree of olisthesis and the DCSA between conventional and axial-loaded MRI were determined. The Pearson's correlation coefficient of the increase in the degree of olisthesis with the reduction in the DCSA during axial loading was calculated. The reduction in the DCSA and the severity of clinical symptoms in patients exhibiting a ≥ 2-mm increase in the degree of olisthesis were compared with those in the patients exhibiting a increase. The increase in the degree of olisthesis was significantly correlated with the reduction in the DCSA during axial loading (Pearson's correlation coefficient = 0.63; pincrease in the degree of olisthesis (26 ± 3 mm(2)) was significantly greater than in those with a increase (13 ± 2 mm(2)) (pincrease in the degree of olisthesis (117 ± 19 m and 6.7 ± 0

    To evaluate the feasibility of computed tomography (CT)- and fluoroscopy-guided percutaneous screw fixation for the treatment of low-grade isthmic spondylolisthesis in adults. Ten consecutive adult patients (four men and six women; mean age: 57.1 [range, 44-78 years]) were prospectively treated by percutaneous screw fixation for low-grade (six grade 1 and four grade 2) isthmic spondylolisthesis of L5. For each patient, two 4.0-mm Asnis III cannulated screws were placed to fix the pars interarticularis defects. All procedures were performed under local anaesthesia by using CT and fluoroscopy guidance. Post-operative outcome was assessed using the visual analogue scale and Oswestry Disability Index (ODI) scores. The procedure time ranged from 45 to 60 min. The mean screw length was 27 mm (range, 24-32 mm). The VAS and ODI measurements {+-} SD decreased from 7.8 {+-} 0.9 preoperatively to 1.5 {+-} 1.1 at the last 2-year follow-up, and from 62.3 {+-} 17.2 to 15.1 {+-} 6.0, respectively (P < 0.001 in both cases). Neither slip progression nor screw failure was noted. This feasibility study showed that CT- and fluoroscopy-guided percutaneous screw fixation could be a rapid, safe and effective method of treating low-grade isthmic spondylolisthesis. (orig.)

    The role of transitional vertebra in spondylolisthesis is still an enigma. Theoretically, obstruction of movements in the L5-S1 joint should provoke hypermobility at the L4-L5 vertebrae, thus leading to the development of spondylolisthesis. The aim of this study was to inquire whether a positive association exists between sacralization and spondylolisthesis. For this purpose, CT images of 436 consecutive patients were examined for the presence of sacralization and spondylolisthesis. The sample was divided into two groups: a sacralization group and non-sacralization group. Independent variables considered were age, sex and degree of lordosis. Sacralization was found in 13.1% of the individuals examined. It was found to be gender- and age-independent (P>0.05), Spondylolisthesis was identified in 7.3% of the individuals examined and found to be gender independent (P>0.05), and age dependent (Pspondylolisthesis was found. The mean lordosis angle in the spondylolisthesis group was 60.41° compared with 50.84° in patients without spondylolisthesis. No association was found between sacralization and the angle of lordosis (P>0.05). The current study did not reveal an association between sacralization and spondylolisthesis and as such sacralization should not be considered an etiology for the development of degenerative spondylolisthesis.

    Patients presenting with stenosis associated with a spondylolisthesis will often describe signs and symptoms consistent with neurogenic claudication, radiculopathy, and/or low-back pain. The primary objective of surgery, when deemed appropriate, is to decompress the neural elements. As a result of the decompression, the inherent instability associated with the spondylolisthesis may progress and lead to further misalignment that results in pain or recurrence of neurological complaints. Under these circumstances, lumbar fusion is considered appropriate to stabilize the spine and prevent delayed deterioration. Since publication of the original guidelines there have been a significant number of studies published that continue to support the utility of lumbar fusion for patients presenting with stenosis and spondylolisthesis. Several recently published trials, including the Spine Patient Outcomes Research Trial, are among the largest prospective randomized investigations of this issue. Despite limitations of study design or execution, these trials have consistently demonstrated superior outcomes when patients undergo surgery, with the majority undergoing some type of lumbar fusion procedure. There is insufficient evidence, however, to recommend a standard approach to achieve a solid arthrodesis. When formulating the most appropriate surgical strategy, it is recommended that an individualized approach be adopted, one that takes into consideration the patient's unique anatomical constraints and desires, as well as surgeon's experience.

    Objective To investigate the impact of radiographic parameters on the 4th lumbar (L4) degenera-tive spondylolisthesis (DLS). Methods From May 2012 to September 2014, 56 patients with L4 degenerative spondy-lolisthesis were enrolled in DLS group, and 56 healthy volunteers were recruited in control group. The participants in both the two groups underwent lumbar lateral X-ray, CT and bone density examination. A series of radiographic pa-rameters were measured on the basis of X-ray and CT results. Logistic regression analysis was used to analyze the risk radiographic parameters of development of DLS. Results In DLS group, 49 cases of L4 spondylolisthesis were classi-fied into gradeⅠand 7 cases of L4 spondylolisthesis were classified into gradeⅡ, with the average Boxall index of (0.195±0.041). Compared with the control group, disc height, L4 vertebral size, disc index and vertebral bone miner-al density of DLS group were significantly lower (P<0.05), but L4 vertebra inclination angle, lumbar lordosis, pelvic incidence, lumbosacral angle of the DLS group were significantly larger (P<0.05). Patients in DLS group had more sagittally orientated facet joints, more significant facet joints tropism and more horizontally orientated pedicle-facet angle than the control group (P<0.05). Logistic regression analysis showed that disc index, L4 vertebral body size, L4 vertebra tilt, lumbar lordosis, pelvic incidence angle and facet joints were the risk factors of the L4 spondylolisthesis.

    Spondylolisthesis coexisting with tuberculosis is rarely reported. There is a controversy whether spondylolisthesis coexists or precedes tuberculosis. Few cases of pathological spondylolisthesis secondary to tuberculous spondylodiscitis have been reported in the lumbar and lumbosacral spine. All cases in the literature presented as anterolisthesis, except one which presented as posterolisthesis of lumbar spine. Spondylolisthesis in the cervical spine is mainly degenerative and traumatic. Spondylolisthesis due to tuberculosis is not reported in the lower cervical spine. The exact mechanism of such an occurrence of spondylolisthesis with tuberculosis is sparsely reported in the literature and inadequately understood. We report a rare case of high grade pathological posterolisthesis of the lower cervical spine due to tubercular spondylodiscitis in a 67-year-old woman managed surgically with a three-year follow-up period. This case highlights the varied and complex presentation of tuberculosis of the lower cervical spine and gives insight into its pathogenesis, diagnosis, and management.

    Study Design  An international, multicenter cross-sectional image-based study performed in 33 institutions in the Asia Pacific region. Objective  The study addressed the role of facet joint angulation and tropism in relation to L4–L5 degenerative spondylolisthesis (DS). Methods  The study included 349 patients (63% females; mean age: 61.8 years) with single-level DS; 82 had no L4–L5 DS (group A) and 267 had L4–L5 DS (group B). Axial computed tomography and magnetic resonance imaging were utilized to assess facet joint angulations and tropism (i.e., asymmetry between facet joint angulations) between groups. Results  There was a statistically significant difference between group A (left mean: 46.1 degrees; right mean: 48.2 degrees) and group B (left mean: 55.4 degrees; right mean: 57.5 degrees) in relation to bilateral L4–L5 facet joint angulations (p < 0.001). The mean bilateral angulation difference was 7.4 and 9.6 degrees in groups A and B, respectively (p = 0.025). A critical value of 58 degrees or greater significantly increased the likelihood of DS if unilateral (adjusted OR: 2.5; 95% CI: 1.2 to 5.5; p = 0.021) or bilateral facets (adjusted OR: 5.9; 95% CI: 2.7 to 13.2; p < 0.001) were involved. Facet joint tropism was found to be relevant between 16 and 24 degrees angulation difference (adjusted OR: 5.6; 95% CI: 1.2 to 26.1; p = 0.027). Conclusions  In one of the largest studies assessing facet joint orientation in patients with DS, greater sagittal facet joint angulation was associated with L4-L5 DS, with a critical value of 58 degrees or greater increasing the likelihood of the condition for unilateral and bilateral facet joint involvement. Specific facet joint tropism categories were noted to be associated with DS. PMID:27433424

    Full Text Available Background: Spondylolisthesis is a common cause of surgery in patients with lower back pain. Although posterolateral fusion and pedicle screw fixation are a relatively common treatment method for the treatment of spondylolisthesis, controversy exists about the necessity of adding interbody fusion to posterolateral fusion. The aim of our study was to assess the functional disability, pain, and complications in patients with spondylolisthesis treated by posterolateral instrumented fusion (PLF with and without transforaminal lumbar interbody fusion (TLIF in a randomized clinical trial. Materials and Methods: From February 2007 to February 2011, 50 adult patients with spondylolisthesis were randomly assigned to be treated with PLF or PLF+TLIF techniques (25 patients in each group by a single surgeon. Back pain, leg pain, and disability were assessed before treatment and until 2 years after surgical treatment using visual analog scale (VAS and oswestry disability index (ODI. Patients were also evaluated for postoperative complications such as infection, neurological complications, and instrument failure. Results: All patients completed the 24 months of follow-up. Twenty patients were females and 30 were males. Average age of the patients was 53 ± 11 years for the PLF group and 51 ± 13 for the PLF + TLIF group. Back pain, leg pain, and disability score were significantly improved postoperatively compared to preoperative scores (P < 0.001. At 3 months of follow-up, there was no statistically significant difference in VAS score for back pain and leg pain in both groups; however, after 6 months and 1 year and 2 years follow-up, the reported scores for back pain and leg pain were significantly lower in the PLF+TLIF group (P < 0.05. The ODI score was also significantly lower in the PLF+TLIF group at 1 year and 2 years of follow-up (P < 0.05. One screw breakage and one superficial infection occurred in the PLF+TLIF group, which had no statistical

    1999-01-01

    Full Text Available Twenty-four cases of sporadic olivo-ponto-cerebellar atrophy (OPCA of adult onset were studied over a period of two years. Results suggest that this disorder has its usual onset in the 5th and 6th decade of life with a male: female ratio of 2:1. It manifests clinically with gait ataxia in all, dysarthria, other cerebellar signs and autonomic involvement in vast majority. There were features of basal ganglia involvement in some. No known identifiable environmental cause was found and genetically they are quite distinct from the known autosomal dominant spinocerebellar ataxias though sporadic occurrence in recessive inheritance or a de novo mutation could not be ruled out completely, but it is unlikely.

    Full Text Available Introduction. The use of extreme lateral interbody fusion (XLIF and other lateral access surgery is rapidly increasing in popularity. However, limited data is available regarding its use in scoliosis surgery. The objective of this study was to evaluate the clinical outcomes of adults with degenerative lumbar scoliosis treated with XLIF. Methods. Thirty consecutive patients with adult degenerative scoliosis treated by a single surgeon at a major academic institution were followed for an average of 14.3 months. Interbody fusion was completed using the XLIF technique with supplemental posterior instrumentation. Validated clinical outcome scores were obtained on patients preoperatively and at most recent follow-up. Complications were recorded. Results. The study group demonstrated improvement in multiple clinical outcome scores. Oswestry Disability Index scores improved from 24.8 to 19.0 (P < 0.001. Short Form-12 scores improved, although the change was not significant. Visual analog scores for back pain decreased from 6.8 to 4.6 (P < 0.001 while scores for leg pain decreased from 5.4 to 2.8 (P < 0.001. A total of six minor complications (20% were recorded, and two patients (6.7% required additional surgery. Conclusions. Based on the significant improvement in validated clinical outcome scores, XLIF is effective in the treatment of adult degenerative scoliosis.

    Full Text Available We evaluate the efficacy-safety of percutaneous vertebroplasty (PV as primary treatment in adult degenerative scoliosis. During the last 4 years, PV was performed in 18 adult patients (68 vertebral bodies with back pain due to degenerative scoliotic spine. Under anaesthesia and fluoroscopy, direct access to most deformed vertebral bodies was obtained by 13G needles, and PMMA for vertebroplasty was injected. Scoliosis’ inner arch was supported. Clinical evaluation included immediate and delayed studies of patient’s general condition and neurological status. An NVS scale helped assessing pain relief, life quality, and mobility improvement. Comparing patients’ scores prior to (mean value 8.06±1.3 NVS units, the morning after (mean value 3.11±1.2 NVS units, at 12 (mean value 1.67±1.5 NVS units, and 24 months after vertebroplasty (mean value 1.67±1.5 NVS units treatment, patients presented a mean decrease of 6.39±1.6 NVS units on terms of life quality improvement and pain relief (P=0.000. Overall mobility improved in 18/18 (100% patients. No complications were observed. During follow-up period (mean value 17.66 months, all patients underwent a mean of 1.3 sessions for facet joint and nerve root infiltrations. Percutaneous vertebroplasty in the inner arch seems to be an effective technique for supporting adult degenerative scoliotic spine.

    Spondylolysis is a common condition, but CT findings have been paid relatively scanty attention in journal publication. The authors reviewed lumbar spine CT of 42 patients who were diagnosed as spondylosis and/or spondylolisthesis in Gyeong Sang National University Hospital. The results were as follows. 1. In 27 cases of spondylolysis, it most frequently occurred at L5 (55.5%) with 88.3% of bilaterality. The defeat of the pars interarticularis was most clearly visible on the slice at or just above the neural foramen. The appearance of the defect had a horizontal plane(88.9%), an irregular surface(85.1%), a non sclerotic margin(88.9%), and a medial proturbance of the medial aspect of the bone just anterior to the defect(77.8%). Spondylolisthesis was associated in 20 of 27 cases(74%), which was demonstrated as an elongation of the anteroposterior diameter of the spinal canal and a pseudobulging disk at defect level in all cases. The degree of the anterior displacement was Grade I in fourteen(55.6%) and Grade II in five(18.7%). 2. Degenerative spondylolisthesis was found in 18 cases and most frequently occurred at L4-5 level(83.3%). The characteristic findings were a vertically-oriented joint plane(66.7%), a posterior displacement of the anterior facet with reference to the posterior facet(50%), bony spurs in the anterior facet(94.1%), a vacuum facet joint(55.6%), and an increased facet joint distance(50%). 3. Spinal stenosis and disk herniation were two most frequent associated abnormalities. They were found at a rate 44.4% and 14.8% in spondylolysis and at a rate 72.2% and 33.3% in degenerative spondylolisthesis. In cases of disk herniation, it frequently occurred just above the level of the defect(2/4) in spondylolysis, in contrast to degenerative spondylolisthesis in which it was most frequent at the same level(4/6). In conclusion, CT must be the highly accurate method for diagnosing and evaluating spondylolysis and all types of spondylolisthesis.

    Abstract Radiographic features of consecutive lumbar spondylolisthesis were retrospectively analyzed in a total of 17 patients treated for this condition at the Third Hospital of Hebei Medical University from June 2005 to March 2012. To investigate the radiographic features, pelvic compensatory mechanisms, and possible underlying etiologies of consecutive lumbar spondylolisthesis. To the best of our knowledge, there is no previous report concerning the characteristics of consecutive lumbar spondylolisthesis. The Taillard index and the lumbar lordosis (LL), pelvic incidence (PI), sacrum slope (SS), and pelvic tilt (PT) were determined on lateral X-ray images, and the angular displacement was analyzed on flexion–extension X-ray images. Correlation between LL and various pelvic parameters and correlation between Taillard index and angular displacement were assessed by Pearson correlation analysis. A total of 20 cases of isthmic spondylolisthesis and 14 of degenerative spondylolisthesis were retrospectively studied in 17 patients. The Taillard index and the angular displacement in the lower vertebrae were both larger than those in the upper vertebrae. Statistical analysis revealed that LL was correlated with PI and PT, whereas PI was correlated with PT and SS. However, no correlation was identified between Taillard index and angular displacement. In consecutive lumbar spondylolisthesis, the degree of vertebral slip and the angular displacement of the lower vertebrae were both greater than those of the upper vertebrae, indicating that the compensatory mechanism of the pelvis plays an important role in maintaining sagittal balance.

    The ideal surgical treatment of spondylolisthesis still remains controversial. There are several methods of treatment and posterior lumbar interbody fusion (PLIF) is one of them. We analyze the results of spondylolisthesis treated by PLIF in term of radiological union, improvement of pre-operative symptoms like back pain, radiating pain and return to normal activities including that of employment, by the review of the medical records. Total of 72 patients, 20 male and 52 female and the age ranges from 15 to 68 years with the mean age being 44.38 years were included in the study. Thirty (41.66%) patients had isthmic spondylolisthesis, 26 (36.12%) had congenital spondylolisthesis, and 16 (22.22%) cases had degenerative spondylolisthesis. There were 38 (52.77%) cases of grade I, 14 (19.44%) cases of grade II and 20 (27.77%) cases of grade III according to the grading criteria of Meyerding. According to the evaluation criteria used by Stauffer and Coventry, 59 patients (81.94%) got good results, eight patients (11.11%) belonged to the fair group and five cases (6.94%) had the poor results. This study showed that PLIF is one of the effective and reliable techniques for the management of spondylolisthesis.

    The defect in the pars interarticularis of spondylolisthesis may be dependent on contributing factors related to trauma and stress to which the neural arch is subjected, superimposed on a hereditary diasthesis. Posterior wedging of 5th lumber vertebral body in lumbosacral spondylolisthesis together with the degree of slip have been measured. The average wedging in spondylolisthesis is significantly greater than patient without this condition, and forms a characteristic radiological sign. The degree of wedging and slip show a statistically valid correlation. The diagnosis of spondylolisthesis is becoming more prevalent as the complexity of our society result in the increasing use of roentgenography of the lumbar spine. Isolated lateral deviation and rotation of spinous process seen in anteroposterior radiographs of the lumbar spine seems to be associated with pathology in the pars interarticularis.

    Full Text Available Abstract Background The operative treatment of adult degenerative scoliosis combined with osteoporosis increase following the epidemiological development. Studies have confirmed that screws in osteoporotic spines have significant lower-screw strength with more frequent screw movements within the vertebra than normal spines. Screws augmented with Polymethylmethacrylate (PMMA or with autogenous bone can offer more powerful corrective force and significant advantages. Methods A retrospective analysis was conducted on 31 consecutive patients with degenerative lumbar scoliosis combined with osteoporosis who had surgery from December 2000. All had a minimum of 2-year follow-up. All patients had posterior approach surgery. 14 of them were fixed with pedicle screw by augmentation with Polymethylmethacrylate (PMMA and the other 17 patients with autogenous bone. Age, sex and whether smoking were similar between the two groups. Surgical time, blood loss, blood transfusion, medical cost, post surgery ICU time, hospital day, length of oral pain medicines taken, Pre-and postoperative Oswestry disability index questionnaire and surgical revision were documented and compared. Preoperative, postoperative and final follow up Cobb angle, sagittal lumbar curve, correction rate, and Follow up Cobb loss were also compared. Results No significant differences were found between the autogenous bone group and Polymethylmethacrylate group with regards to all the targets above except for length of oral pain medicines taken and surgery cost. 2 patients were seen leakage during operation, but there is neither damage of nerve nor symptom after operation. No revision was needed. Conclusion Both augmentation pedicle screw with Polymethylmethacrylate (PMMA and autogenous bone treating degenerative lumbar scoliosis combined with osteoporosis can achieve a good surgical result. Less oral pain medicines taken are the potential benefits of Polymethylmethacrylate augmentation, but

    ) patients and L4 degenerative spondylolisthesis (DS) patients during functional weight⁃bearing activities. Methods Fifteen symptomatic L4 IS patients and fifteen symptomatic L4 DS patients were recruited. Fifteen asymptomatic volunteers were en⁃rolled as the control group. The L4,5 vertebral segment motion of each subject was reconstructed using three⁃dimensional computed tomography and a solid modeling software. In vivo, lumbar vertebral motion during functional postures (flexion⁃extension, left⁃right twisting and left⁃right bending) was observed using a dual fluoroscopic imaging technique. The spinal function unit was divided in⁃to anterior and posterior segments by the isthmic cleft. Local coordinate systems were established at the vertebral body, to obtain the 6 degree⁃of⁃freedom (DOF) intervertebral range of motion (ROM) at L4,5 and the ROM between the anterior and the posterior segments of L4 IS. Results The motion of IS at L4,5 was found to be increased. The migrations along both sagittal and vertical axis were significantly larger than control group (P<0.05). During left⁃right twisting, the migration along sagittal axis was significantly larger than control group (P<0.05);the rotation along vertical axis was significantly larger than DS and control group (P<0.05). During left⁃right bending, the migration along frontal axis was significantly larger than DS and control group ( P<0.05). The inter⁃vertebral ROM at L4,5 showed no significant difference between DS and control group. The migration between anterior and posteri⁃or segments of IS L4 was larger in standing than supine (P<0.05). The relative migration along sagittal axis between anterior and posterior segments of IS L4 was significantly larger in flexion than standing (P<0.05). Conclusion A spondylolytic defect does lead to detectable instability or hypermobility in the lumbar spine compared with degenerative spondylolisthesis and normal group.

    Surgical correction of adult degenerative scoliosis is a technically demanding procedure with a considerable complication rate. Extensive blood loss has been identified as a significant factor linked to unfavorable outcome. To report on the complication profile and clinical outcomes obtained with less invasive image-guided surgical correction of degenerative (de novo) scoliosis in a high-risk population. Thirty patients (age, 64-88 years) with progressive postural impairment, back pain, radiculopathy, and neurogenic claudication caused by degenerative scoliosis were treated by less invasive image-guided correction (3-8 segments) by multisegmental transforaminal lumbar interbody fusion and facet fusions. With a mean follow-up of 19.6 months, intraoperative blood loss, curve correction, fusion and complication rates, duration of hospitalization, incidence of hardware-related problems, and clinical outcome parameters were assessed using multivariate analysis. Satisfactory multiplanar correction was obtained in all patients. Mean intraoperative blood loss was 771.7±231.9 mL, time to full ambulation was 0.8±0.6 days, and length of stay was 8.2±2.9 days. After 12 months, preoperative SF12v2 physical component summary scores (20.2±2.6), visual analog scale scores (7.5±0.8), and Oswestry disability index (57.2±6.9) improved to 34.6±3.9, 2.63±0.6, and 24.8±7.1, respectively. The rate of major and minor complications was 23.4% and 59.9%, respectively. Ninety percent of patients rated treatment success as excellent, good, or fair. Less invasive image-guided correction of degenerative scoliosis in elderly patients with significant comorbidity yields a favorable complication profile. Significant improvements in spinal balance, pain, and functional scores mirrored expedited ambulation and early resumption of daily activities. Less invasive techniques appear suitable to reduce periprocedural morbidity, especially in elderly patients and individuals with significant

    Adult degenerative scoliosis associated with lumbar stenosis has become a common issue in the elderly population. But its surgical management is on debating. The main issue condenses on the management priority of scoliosis or stenosis. This study is to investigate surgical management strategy and outcome of adult degenerative scoliosis associated with lumbar stenosis. Between January 2003 and December 2010, 108 patients were admitted to the authors' institution for adult degenerative scoliosis associated with lumbar stenosis. They were divided into 3 groups based on the symptom. Then the surgical management was carried out. The clinical outcome was evaluated according to the Oswestry Disability Index (ODI) and Scoliosis Research Society-22 score (SRS-22 score) at follow up. Group 1 was with primary lumbar stenosis symptom, local decompression and short fusion were performed. Group 2 was with compensated spinal imbalance symptom, local decompression of the symptomatic spinal stenosis and short fusion were performed. Group 3 was with primary spinal imbalance, correction surgery and long fusion were performed. For Group 1, the ODI scores declined from 62.5 ± 4.2 preoperatively to 21.8 ± 2.5 at final follow up, the SRS-22 scores decreased from 44.8 ± 3.2 preoperatively to 70.9 ± 6.0 at final follow up. For Group 2, the ODI and SRS-22 scores were 73.4 ± 8.4 and 40.8 ± 8.5 before the surgery, declined to 22.4 ± 4.2 and 73.2 ± 7.9 at final follow up. For Group 3, the ODI and SRS-22 scores were 73.4 ± 4.9 and 45.3 ± 6.4 before surgery, declined to 30.4 ± 8.9 and 68.8 ± 8.1 at final follow up. It was effective to perform decompression and short fusion for Group 1 and correction surgery and long fusion for Group 3. For Group 2, the compensated imbalance symptom was always provoked by the symptomatic lumbar stenosis. The cases in the Group 2 got well clinical improvements after local surgical intervene on the

    To define the clinical phenotype and natural history of sporadic adult-onset degenerative ataxia and to identify putative disease-causing mutations. The primary measure of disease severity was the Scale for the Assessment and Rating of Ataxia (SARA). DNA samples were screened for mutations using a high-coverage ataxia-specific gene panel in combination with next-generation sequencing. The analysis was performed on 249 participants. Among them, 83 met diagnostic criteria of clinically probable multiple system atrophy cerebellar type (MSA-C) at baseline and another 12 during follow-up. Positive MSA-C criteria (4.94 ± 0.74, p 10 years were designated sporadic adult-onset ataxia of unknown etiology/non-MSA (SAOA/non-MSA). Compared with MSA-C, SAOA/non-MSA patients had lower SARA scores (13.6 ± 6.0 vs 16.0 ± 5.8, p = 0.0200) and a slower annual SARA increase (1.1 ± 2.3 vs 3.3 ± 3.2, p = 0.0013). In 11 of 194 tested participants (6%), a definitive or probable genetic diagnosis was made. Our study provides quantitative data on the clinical phenotype and progression of sporadic ataxia with adult onset. Screening for causative mutations with a gene panel approach yielded a genetic diagnosis in 6% of the cohort. NCT02701036. © 2017 American Academy of Neurology.

    Seventeen patients with lytic lumbar spondylolisthesis (Meyerding grade I-II) and radicular symptoms were examined by epidurography in addition to radiculomyelography before surgical treatment. Epidurography is considered more suitble than radiculomyelogrphy for assessing this condition because narrowing of the epidural space and compression of the nerve roots, due to osteofibrous changes at the lysis, are more consistently demonstrated.

    Lumbar spondylolisthesis is a common finding on plain radiographs. The condition has a variety of causes which can be differentiated on the basis of imaging findings. As the treatment is dependent upon the type of spondylolisthesis, it is important for the radiologist to be aware of these features. We present a pictorial review of the imaging features of lumbar spondylolisthesis and explain the differentiating points between different groups of this disorder. The relative merits of the different imaging techniques in assessing lumbar spondylolisthesis are discussed.

    We present the case of a patient with a spondylolisthesis of L5 on S1 due to spondylolysis at the level L5/S1. The vertebral slip was fixed and no anterior instability was found. Using functional magnetic resonance imaging (MRI) in an upright MRI scanner, posterior instability at the level of the spondylolytic defect of L5 was demonstrated. A structure, probably the hypertrophic ligament flava, arising from the spondylolytic defect was displaced toward the L5 nerve root, and a bilateral contact of the displaced structure with the L5 nerve root was shown in extension of the spine. To our knowledge, this is the first case described of posterior instability in patients with spondylolisthesis. The clinical implications of posterior instability are unknown; however, it is thought that this disorder is common and that it can only be diagnosed using upright MRI.

    A retrospective study. To summarize and describe the radiographic parameters of adult degenerative scoliosis (ADS) and explore the radiological parameters which are significantly different in sagittal balanced and imbalanced ADS patients. ADS is the most common type of adult spinal deformity. However, no comprehensive description of radiographic parameters in ADS patients has been made, and few studies have been performed to explore which radiological parameters are significantly different between sagittal balanced and imbalanced ADS patients. Medical records of ADS patients in our outpatient clinic from January 2012 to January 2014 were reviewed. Demographic data including age and sex, and radiographic data including the coronal Cobb angle, location of apical vertebra/disc, convexity of the curve, degree of apical vertebra rotation, curve segments, thoracic kyphosis (TK), lumbar lordosis (LL), thoracolumbar kyphosis (TL), sacral slope (SS), pelvic tilt (PT), pelvic incidence (PI), sagittal vertical axis (SVA), and PI minus LL (PI-LL) were reviewed to make comprehensive description of radiographic parameters of ADS. Furthermore, patients were divided into 2 groups according to whether the patients' sagittal plane was balanced: Group A (imbalanced, SVA > 5 cm) and Group B (balanced, SVA  ≤ 5 cm). Demographic and radiological parameters were compared between these 2 groups. A total of 99 patients were included in this study (Group A = 33 and Group B = 66; female = 83 and male = 16; sex ratio = 5:1). The median of age were 67 years (range: 41-92 years). The median of coronal Cobb angle and length of curve was 23 (range: 10-75°) and 5 segments (range: 3-7), respectively. The most common location of apical vertebra was at L2 to L3 (81%) and the median of degree of apical vertebra rotation was 2° (range: 1-3). Our study also showed significant correlations between coronal Cobb angle and curve segments (r = 0.23, P sagittal balance, there were significant

    Spinal CT scans of 680 patients with suspected disc herniation were reviewed to detect lumbar spondylolysis. In this group of patients, 3.23% (n=22) had pars interarticularis defects at L4 or L5. Disc herniation at the interspace of the pars defect was seen in 27.27% (6/22) of patients with spondylolysis. Using Meyerding's method, which measures the degree of vertebral forward dislocation, grade 2 and grade 3 spondylolisthesis were most often seen. While moderate and severe spondylolisthesis can be already detected via lateral localiser image (scout view), pars defects with only little forward dislocation can be easily underdiagnosed. Sources of diagnostic error are: 1. an atypically posterior disc margin which extends beyond only one vertebral body and presents the appearance of disc herniation, 2. pars defects simulating the adjacent facet joints involve the risk of overlooking spondylolysis, 3. CT sections made through the intervertebral discs and facet joints only, may fail to show up the pars defect 10 or 15 mm above the disc plane.

    OBJECTIVE The objective of this study was to assess the cross-sectional areas (CSAs) of lumbar paraspinal muscles in adults with isthmic spondylolisthesis (IS), to compare them with those in the normative population, and to evaluate their correlations with demographic factors and MRI changes in various spinal elements. METHODS The authors conducted a retrospective study of patients who had undergone posterior lumbar interbody fusion for IS, and 2 of the authors acting as independent observers calculated the CSAs of various lumbar paraspinal muscles (psoas, erector spinae [ES], multifidus [MF]) on preoperative axial T2-weighted MR images from the L-3 to L-5 vertebral levels and computed the CSAs as ratios with respect to the corresponding vertebral body areas. These values were then compared with those in an age- and sex-matched normative population and were analyzed with respect to age, sex, duration of symptoms, grade of listhesis, and various MRI changes at the level of the listhesis (pedicle signal change, disc degeneration, and facetal arthropathy). RESULTS Compared with values in normative controls, the mean CSA value for the ES muscle was significantly higher in the study cohort of 120 patients (p = 0.002), whereas that for the MF muscle was significantly lower (p = 0.009), and more so in the patients with PSC (p = 0.002). Magnetic resonance imaging signal change in the pedicle was seen in half of the patients, all of whom demonstrated a Type 2 change. Of the variables tested in a multivariate analysis, age independently predicted lower area values for all 3 muscles (p ≤ 0.001), whereas female sex predicted a lower mean psoas area value (p < 0.001). None of the other variables significantly predicted any of the muscle area values. A decrease in the mean MF muscle area value alone was associated with a significantly increased likelihood of a PSC (p = 0.039). CONCLUSIONS Compared with normative controls, patients with IS suffer selective atrophy of their MF

    Planar bone scintigraphy (PBS) and single-photon emission computed tomography (SPECT) were compared in 19 adults with radiographic evidence of spondylolysis and/or spondylolisthesis. SPECT was more sensitive than PBS when used to identify symptomatic patients and sites of painful defects in the pars interarticularis. In addition, SPECT allowed more accurate localization than PBS. In 6 patients, spondylolysis or spondylolisthesis was unrealted to low back pain, and SPECT images of the posterior neural arch were normal. The authors conclude that when spondylolysis or spondylolisthesis is the cause of low back pain, pars defects are frequently heralded by increased scintigraphic activity which is best detected and localized by SPECT.

While majority are asymptomatic, a subset do produce pain with neurology. Complete decompression of roots is essential, as is the need for solid stabi lization. Several fusion techniques were reported in literature like PLF, TLIF, PLF, ALIF On theoretical grounds, TLIF has been suggested to be safe and result in an improved outcome compared to other techniques. Data to support this view, are lacking. M ETHODS: A total of 21 patients (age range, 27 - 62 years with adult isthmic and degenerative spondylolisthesis were operated. There were 8 males and 13 females with mean age of 46.8 pre - op and 2 - year follow - up, pain (VAS and functional disability were quan tified by Oswestry Disability Index (ODI.Radiological union assessed with xrays by Brantigen and Steffee criteria. The global outcome was excellent in 90%.and 92% fusion. 2 patients presented motor deficit which did not recover. RESULTS: The follow - up was for 2 years. The mean VAS score for low back pain improved from 7.0 preoperatively to 2.1, as did the mean VAS score for leg pain from 6.7 to 1.4 and the mean ODI from 59.5% to 11.3%. CONCLUSION: TLIF does affect the 2 - year outcome of surgical treatment of spondylolisthesis with decreased back pain and ODI’s, with advantages of minimal thecal retraction, restored segmental lordosis and preserved posterior tension band.

    Full Text Available ABSTRACT Objective: To define and quantify the degree of change of the spinal canal diameter in patients with degenerative and spondylolytic spondylolisthesis. Methods: We studied CT scans of 54 patients. Of this total, 37 (29 women and 8 men had degenerative type and 17 (7 women and 10 men had spondylolytic type. Results: In the degenerative spondylolisthesis group, the average diameter of the spinal canal at the injured vertebra level was 17.35 mm and 17.64 mm for the upper vertebra level. The average diameter of the foramen at the level of the affected vertebra was 14.61 mm to left side and 15.00 mm to the right side. The average diameter of the foramen at the upper vertebra level was 16.82 mm to the left side and 16.51 mm to the right side. In the spondylolytic group, the average diameter of the spinal canal at the level of the affected vertebra was 23.25 mm and at the upper vertebra level was 18.66 mm. The average diameter of the foramen at the level of the affected vertebra was 11.98 mm to the left side and 12.34 mm to the right side. The average diameter of the foramen at the level of the upper vertebra was 16.97 mm to the left side and 15.58 mm to the right side. Conclusion: The diameter of the spinal canal in the sagittal plane showed no statistically significant increase in the spondylolytic spondylolisthesis group, in contrast to what is found in the degenerative spondylolisthesis group. It was also observed a reduction in vertebral foramina of the injured level in both groups.

    Spondylolisthesis is displacement of one vertebra upon the other with bony defect of neural arch or elongation of the pars interarticularis. Radiological findings of 35 confirmed cases of spondylolisthesis on plain film and myelogram were reviewed. We also compared the size and contour of slipped vertebra, and myelographic findings between L4-L5 (12 cases) and L5-S1 (23 cases) listhesis. The results were as follows: 1. Average of posterior wedging index of the body, foreward displacement, narrowing of intervertebral disc space and the degenerative changes are more severe in L5-S1 spondylolisthesis. 2. Hyperplastic changes of slipped vertebra are more severe in L5-S1 listhesis. 3. Incidence of spina bifida is not co-related between L4-L5 and L5-SI listhesis. 4. Arthrosis of the intervertebral joint appears both below and above the level of L5-S1 listhesis, but rare in L4-L5 listhesis. 5. The L5 root seems to be the one most often affected in lumber spondylolisthesis on myelogram. 6. The diagnosis of intervertebral disc herniation is less relable in patient with listhesis than in patients without listhesis.

    Trauma to the back from the force of chronic stress is thought to be an etiologic factor in isthmic spondylolisthesis (SLL). The relationship of first degree spondylolisthesis to low back pain (LBP) is controversial. We compare the prevalence of SLL in helicopter pilots who are subject to strong vibrational forces, with other airforce personnel. Helicopter pilots had more than a four times higher prevalence of SLL (4.5%) than did cadets (1.0%) and transport pilots (0.9%). Low back pain was more frequent in pilots with SLL than in those without this lesion but in no case was the pain disabling or the defect progressive. We conclude that SLL may be induced by vibrational forces and although SLL is associated with LBP, the pain was little clinical significance.

    The purpose of this paper is to evaluate and analyze the radiological findings of 13 cases of lumbar spondylolisthesis with intact neural arch at Han-Gang Sung- Shim Hospital during period from Jan. 1975 to June 1980. 1. The age distribution of the patients varied from 31 to 83 years old. The average of the age was 53 years old. 12 patients were female and only one patient was male. 2. All cases revealed anterior slipping of the L4 body on the L5 body, of which degree was classified by Meyerding's method, first degree in 12 patients and second degree in one patient. 3. The angle between the pedicle and inferior articular facet of affected vertebra was measured by Junghann's method. The average of angle was 123 degree. 4. Of 13 cases, 2 cases who had neural compression caused by dislocation of the vertebral bodies and intrusion of lamina and arthritic facets into stenotic spinal canal treated by laminar decompression including foraminotomy. Good results were obtained. 5. The secondary degenerative change of the vertebra was considered to be the cause of the spondylolisthesis with intact neural arch.

    Degenerative disease of the spine is a definition that includes a wide spectrum of degenerative abnormalities. Degeneration involves bony structures and the intervertebral disk, although many aspects of spine degeneration are strictly linked because the main common pathogenic factor is identified in chronic overload. During life the spine undergoes continuous changes as a response to physiologic axial load. These age-related changes are similar to pathologic degenerative changes and are a common asymptomatic finding in adults and elderly persons. A mild degree of degenerative changes is paraphysiologic and should be considered pathologic only if abnormalities determine symptoms. Imaging allows complete evaluation of static and dynamic factors related to degenerative disease of the spine and is useful in diagnosing the different aspects of spine degeneration.

    Neurodevelopmental and neurodegenerative theories may be viewed as incompatible accounts that compete to explain the pathogenesis of schizophrenia. However, it is possible that neurodevelopmental and neurodegenerative processes could both reflect common underlying causal mechanisms. We hypothesized that cognitive dysfunction would gradually deteriorate over time in schizophrenia and the degree of this deterioration in adulthood would be predicted by an infant measure of neurodevelopment. We aimed to examine the association between age of learning to stand in infancy and deterioration of cognitive function in adulthood. Participants were nonpsychotic control subjects (n = 76) and participants with schizophrenia (n = 36) drawn from the Northern Finland 1966 Birth Cohort study. The schizophrenia group showed greater deterioration in abstraction with memory than controls, but there were no differences between schizophrenia and controls in rate of change of other cognitive measures. Age of learning to stand in infancy significantly inversely predicted later deterioration of abstraction with memory in adult schizophrenia (later infant development linked to greater subsequent cognitive deterioration during adulthood), possibly suggesting a link between abnormal neurodevelopmental and neurodegenerative processes in schizophrenia.

    Patients with back pain and degenerative disorders of the spine have a significant impact on health care costs. Some authors estimate that up to 80% of all adults experience back pain at some point in their lives. Disk herniation represents one of the most frequent causes. Nevertheless, other degenerative diseases have to be considered. In this paper, pathology and imaging of degenerative spine diseases will be discussed, starting from pathophysiology of normal age-related changes of the intervertebral disk and vertebral body.

    Unilateral spondylolytic spondylolisthesis may cause lateral tilt of the overlying spinous processes towards the normal isthmus on PA views. Bilateral spondylolytic spondylolisthesis is generally located at the L5-S1 level. The vertebral shift is usually moderate. Instability at the level of spondylolisthesis may be demonstrated by stress lateral views but is uneasy to quantify. In case of sciatica associated to spondylolisthesis, foramen stenosis is probably the most frequent cause but foramen compression of the spinal ganglion is difficult to assess on imaging.

    Objectives: To compare the different impact on saggital spinopelvic alignment in degenerative spondylolisthesis between minimally invasive transforaminal lumbar interbody fusion (TLIF) and conventional open posterior lumbar interbody fusion(PLIF). Methods: From June 2010 to June 2013, 48 patients with L4 single segmental degenerative spondylolisthesis met the inclusion criteria underwent traditional open PLIF in 23 cases(OPEN group) and minimally invasive TLIF in 25 cases(MIS group), and the clinical data were ana-lyzed retrospectively. The following data of preoperation and final follow-up were compared between the two groups on the standing lateral lumbar X-ray which containing bilateral femoral heads: slip percentage (SP), lumbar lordosis(LL), pelvic incidence(PI), pelvic tilt(PT), sacral slop(SS), lumbosacral angle(LSA), slip angle(SA) and the L1 axis and S1 distance(LASD). The correlation between the parameters was analyzed using correlate analysis. Results: The rate of slip reduction(ΔSP) in OPEN group was (67.42±33.80)%, which was significant-ly higher than that in MIS group (36.59±50.68)%(P<0.05). The LL at final follow-up was 43.03°±14.07°, SA was 3.12°±4.02°, which were both significantly lower than preoperative ones (46.53°±15.72° and 6.10°±5.64°respectively) in MIS group(P<0.05). ΔSA in OPEN group was 2.53°±6.63°, which was significantly higher than that in MIS group(-2.98°±5.42°)(P<0.05). ΔLASD in OPEN group was -4.10°±14.53°, which was significantly lower than that in MIS group (3.48°±9.01°)(P<0.05). There were positive correlations between preoperative SP and LASD, ΔSA and ΔLL, and negative correlation between ΔLL and ΔPT. Conclusions: For degenerative spondylolisthesis, minimally invasive TLIF and open PLIF all can make a significant reduction to slippage vertebral, but open PLIF has a higher rate of slip reduction. Minimally invasive TLIF significant reduce LL and SA, resulting in relative kyphosis on fusion segment

    Given the indolent natural history of a large number of spondylolyses, care should be taken not to attribute symptoms to the defect unnecessarily, but due regard must be given to complications. Therefore, a spondylolisthesis in conjunction with deformity, symptoms of radiculopathy, disc prolapse or canal stenosis should be investigated beyond diagnostic plane radiographs. Magnetic resonance imaging is most useful, but appreciation of full bony detail is not obtained without CT. Evaluation of progression is still performed with lateral radiographs, and appreciation of the inherent inaccuracies of the various techniques used is necessary to avoid precipitating unnecessary surgery. As the resolution of modern imaging equipment improves, smaller and smaller abnormalities are identified which may alter the apparant prevalence rates and are probably more likely to be less clinically relevant.

    Objective: To evaluate the influence of PI-LL (pelvic incidence minus lumbar lordosis mismatch) on scoliosis correction, living quality and internal fixation related complications for adult degenerative scoliosis (ASD) after long posterior instrumentation and fusion. Methods: A total of 79 patients with ADS underwent long posterior instrumentation and fusion in the Department of Orthopedics at Beijing Chao Yang Hospital from January 2010 to January 2014 were retrospectively reviewed.There were 21 males and 58 females aging from 55 to 72 years with the mean age (63.4±4.8)years. The patients were divided into three groups according to immediately postoperative PI-LL: PI-LL20°.Compare the Cobb's angles, PI-LL, Japanese Orthopaedic Association (JOA) score, Oswestry Disability Index (ODI), Visual Analog Scale (VAS) and Lumbar Stiffness Disability Index (LSDI). Measurement data were compared via t test and ANOVA, enumeration data were compared via Kruskal-Wallis test, noncontiguous data was performed by χ(2) test. Univariate linear regression equation was performed to investigate the relative influences of postoperative PI-LL on postoperative radiographic parameters and clinical outcome. Results: All the operations were successful without intraoperative complications.

    Full Text Available Background: Since centuries ago it has been written about lumbar pain, still its treatment remains enigmatic. At present, all developed spinal surgery institutions use the transpedicular fixation methods, but we lack the right technology for what we use the posterolateral fusion. Objetive: to evaluate the results in the aplicate of the posterolateral fusion in spondylolisthesis of the lumbosacral segment. Methods: A Retrospective-descriptive, correlational, and of a series of cases study, carried out in traumatology and orthopaedics service of the Universitarian Provincial Hospital ¨Dr. Gustavo Aldereguía Lima¨ of Cienfuegos, in which were included the 33 patients with spondylisthesis of the lumbosacral segment, who received inter-transversal posterolateral fusion. All the patients got plain anteroposterior and lateral radiography, including right and left slanting sights, to the doubtful cases dynamic sights with flexion and extension of the trunk were applied. To the patients with signs of radicular irritation, a digitalized axial tomography was applied. Results: The main etiological causes in these patients were the isthmic one, followed by degenerative and dysplastic ones. The posterolateral function was carried out alone or combined with other surgical techniques; to the patients with lumbar pain that also had associated signs of radicular irritation were applied exeresis of posterior arch with release of the endangered roots. The more frequent complication was the recurrent pain, present in 6 patients, followed by granuloma of the surgical wound. Conclusions: In spite of lacking a modern instrumentation system, the problem of spondylolisthesis can be solved with only dominating this traditional technique consistent in posterolateral fixation.

    Full Text Available Objective. To date, there is still no consensus on the treatment of spinal degenerative disease. Current surgical techniques to manage painful spinal disorders are imperfect. In this paper, we aimed to evaluate the prospective results of posterior transpedicular dynamic stabilization, a novel surgical approach that skips the segments that do not produce pain. This technique has been proven biomechanically and radiologically in spinal degenerative diseases. Methods. A prospective study of 18 patients averaging 54.94 years of age with distant spinal segment degenerative disease. Indications consisted of degenerative disc disease (57%, herniated nucleus pulposus (50%, spinal stenosis (14.28%, degenerative spondylolisthesis (14.28%, and foraminal stenosis (7.1%. The Oswestry Low-Back Pain Disability Questionnaire and visual analog scale (VAS for pain were recorded preoperatively and at the third and twelfth postoperative months. Results. Both the Oswestry and VAS scores showed significant improvement postoperatively (P<0.05. We observed complications in one patient who had spinal epidural hematoma. Conclusion. We recommend skipping posterior transpedicular dynamic stabilization for surgical treatment of distant segment spinal degenerative disease.

    To evaluate the factors affecting intervertebral foramen stenosis and nerve root compression in spondylolytic spondylolisthesis. We investigated 120 intervertebral foramina of 60 patients with spondylolytic spondylolisthesis who had undergone lumbar MRI. A retrospective review of their MR images revealed the degree of intervertebral foramen stenosis and causes of nerve root compression. The relationship between disk height diminution following spondylolysis and degree of intervertebral foramen stenosis was also evaluated. Forty eight of 60 patients showed a similar degree of intervertebral foramen stenosis, and in 12 patients the degree of stenosis was different. In 110 intervertebral foramina, stenosis of both the superior and inferior compartments of intervertebral foramina was demonstrated. In 37 of 120 cases (30.8%), stenosis was mild ; in 44 of 120 (36.7%) it was modcrate, and in 29 of 120 (24.2%) it was severe. Stenosis of the inferior compartment was demonstrated in ten of 120 intervertebral foramina (8.3%). Nerve root compression was caused by posterior bulging of the intervertebral disk (65/120), descent of the pedicle (51/120), an isthmic bony segment above the site of spondylolytic (44/120), a bony spur formed at a spondylolytic site (11/120), and fibrocartilaginous callus at a spondylolytic site (5/48). In all cases there was degenerative change of the intervertebral disk at the affected level. There was no relationship between degree of disk height diminution and degree of intervertebral foramen stenosis (p > 0.05). The degree of intervertebral foramen stenosis and causes of nerve root compression in spondylolytic spondylolisthesis are variable, and MRI demonstrates them precisely. There was no positive relationship between degree of nerve root compression at an intervertebral foramen and degree of spondylolysis and degeneration of an intervertebral foramen. The degree of nerve root compression is believed to be another criterion for describing

    The ability to understand factors associated with an increased duration of missed work postoperatively could be used to more effectively select patients with the greatest opportunity for a successful outcome. We set out to determine the effect of preoperative depression on postoperative return to work in patients undergoing transforaminal lumbar interbody fusion (TLIF) for degenerative spondylolisthesis. Fifty-eight patients undergoing TLIF for symptomatic grade I degenerative lumbar spondylolisthesis were included in this analysis. Patient demographics, clinical presentation, indications for surgery, radiologic studies, and operative variables were assessed for each case. Patient-assessed outcome measures were obtained prospectively at baseline and 2 years postoperatively. To understand the factors associated with prolonged return to work, univariate linear regression analysis and stepwise multivariate Cox proportional hazards model was used. All patient-reported outcomes assessed were significantly improved 2 years after TLIF (P working preoperatively, 26 (81%) returned to work postoperatively. Median time to return to work was 56 days (range, 10-150 days). Independent of patient age; preoperative pain, disability, and quality of life; and extent of postoperative improvement, increased preoperative Zung depression score remained associated with prolonged return to work (P = 0.02). Independent of postoperative improvement in pain, disability, and quality of life, the extent of preoperative depression was an independent predictor of time to return to work in patients undergoing TLIF for spondylolisthesis, suggesting that regardless of how successful TLIF surgery may be at improving a patient's pain, disability, or quality of life, greater depression will delay or prohibit their ability to return to work postoperatively.

    Low back pain is a common cause of lost playing time in young athletes, and spondylolysis is its most common identifiable cause. Despite technological advances in radiology, which can lead to an early diagnosis with better prognosis, progression to spondylolisthesis is sometimes asymptomatic and may not be detected until late stages. There are wide variations, suggesting lack of consensus as regards the objective of treatment, which consists of clinical, radiological, biomechanical or functional improvement. There is also a lack of agreement regarding the ideal conservative treatment, surgical indications and need of slip reduction, and most of the established recommendations are not evidence based. We present a review of literature, which summarizes the current knowledge of spondylolysis and spondylolisthesis in children and adolescents.

    The authors retrospectively studied seven patients who had in situ fusion as adolescents for high-grade (IV, V) spondylolisthesis unresponsive to more conservative means. All patients achieved solid bony union; their pain was relieved; and hamstring spasm had resolved. The authors sought to determine whether crouch gait or any other abnormalities could be demonstrated in patients exhibiting clinical parameters of success. Each patient underwent gait analysis, radiographic analysis, and a physical examination. Four of seven patients demonstrated slight degrees of forward trunk lean during varying phases of gait accompanied by increased hip flexion. One patient demonstrated increased trunk extension accompanied by limited hip flexion. Two patients were essentially normal. The authors were unable to quantify residual crouch in these patients with solidly fused high-grade spondylolisthesis.

    Isthmic spondylolisthesis, which is demonstrated in 4%-6% of the general population, is one of the most common types of spondylolisthesis. However, double-level isthmic spondylolisthesis is extremely rare. Only a few reports have examined the outcomes of surgical treatment of double-level spondylolisthesis. The authors present an unusual case of double-level isthmic spondylolisthesis of the lumbar spine. The patient had low-back pain for 20 years and did not respond to conservative treatment. Radiographs revealed bilateral pars defects at L-4 and L-5. Grade 2 isthmic spondylolisthesis was present, both at L4-5 and at L5-S1. The patient underwent decompression, reduction, and posterior lumbar interbody fusion with autogenous bone chips from posterior decompression. At follow-up after 12 months, the patient was free of pain, slippage was corrected, and fusion was achieved. Posterior lumbar interbody fusion with posterior instrumentation and reduction may yield good functional short-term results for double-level spondylolisthesis.

    Full Text Available Background. Degenerative lumbar spinal stenosis (DLSS is a common cause of low back and leg pain in the elderly. Conservative treatment seldom results in sustained improvement.Methods. Fifty-six patients (33 women, 23 men older than 50 years (mean 67 years, range 51 to 82 years and with no prior low back surgery were treated from 1993 to 1999 for clinical and radiologic evidence of DLSS. The goal of this study was to describe the results of decompressive laminectomy with or without fusion in terms of reoperation, severity of back pain, leg pain and patient satisfaction. Answers to Swiss spinal stenosis questionnaires completed before surgery and one to five years afterwards were evaluated. Seven patients (12.5% with degenerative spondylolisthesis, scoliosis and/or more radical facetectomies received fusion.Results. Of the 56 patients in the original cohort, two were deceased and two had undergone reoperation by follow-up. Forty-eight patients answered questionnaires. Average duration of follow-up was 2.5 years. More than 70 percent of the respondents had no or only mild back or buttock pain at follow-up and more than 60 percent were able to walk more than 500 m. Added fusion reduced the incidence of low back pain and pain frequency, and increased walking distance (ANOVA.Conclusions. Eighty-one percent of patients were satisfied with the results of surgery and 87.5% would choose to have the operation again if they had the choice. Decompressive laminectomy for DLSS yields best results if instrumented fusion is included in the procedure.

    We reported the 18 patients which underwent surgical exploration and reviewed these CT findings. Method All CT scans were obtained on Somatom II, high resolution CT scanner, with the patient in the supine position. A lateral localizer image (Topogram) was used to select the appropriate intervertebral disk space. The slice thickness was 4 mm. Results 1) CT findings in lumbar degenerative diseases include bony canal stenosis (central canal stenosis, narrowed lateral recess), soft tissue abnormalities (herniated nucleus pulposus, bulging annulus, hypertrophy and/or ossification of ligamentum flavum, no delineation of nerve root in lateral recess), and spinal instability (spondylolisthesis, vacuum phenomenon). 2) The above three factors contribute to narrowing of spinal canal. 3) No delineation of nerve root or soft tissue replacement of epidural fat in lateral recess suggests that the nerve root may be compressed by some factors. 4) Herniated nucleus pulposus may cause nerve root compression with or without canal stenosis. Conclusion This study revealed that the CT findings correlated closely with the surgical findings and the site of nerve root compression could be determined.

    A series of 202 patients (133 men, 69 women) with lumbar spondylolysis were examined radiographically on two occasions, first at the time of diagnosis and later at a follow-up, after an observation period of 20 years or more. The films from patients in groups without and with moderate and severe olisthesis were evaluated with respect to variables describing lumbosacral lordosis, wedging of the spondylolytic vertebra, lengths of the transverse processes and iliolumbar ligaments, disk height, progression of slipping, and influence on measured olisthesis of lumbar spine flexion and extension at the radiographic examination. The evaluation was made with special attention to possible signs which could be predictive for the prognosis of vertebral slipping. Progression of slipping did not differ between patients diagnosed as adults or adolescents. Reduction of disk height was correlated to the degree of slipping present at the initial examination and to the progression of olisthesis. Flexion and extension of the lumbar spine did not modify the degree of olisthesis. Data concerning the lengths of the transverse processes and the iliolumbar ligaments, and lumbar lordosis, cannot be used for prognostic purposes. The lumbar index reflecting the degree of wedge deformity of the spondylolytic vertebra was shown to be the only variable of prognostic value for the development of vertebral slipping.

    It is necessary to assess coronal Cobb angle in the diagnosis and treatment of patients with adult degenerative scoliosis (ADS). But as most ADS patients are elderly patients who are difficult or unable to stand upright without assistance, it is difficult to obtain standing posteroanterior X-ray radiographs. Whether it is possible to use Cobb angle obtained on a supine posteroanterior X-ray radiograph to predict Cobb angle in a standing position remains unanswered.To study the correlation between X-ray plain radiographic parameters obtained from the supine position and those obtained from the standing position in ADS patients.Medical records and radiological information were obtained from ADS patients prospectively. Posteroanterior X-ray views of the spine were taken in both standing and supine positions simultaneously in the same ADS patients to record information about the position of the apical and end vertebrae in the coronal position and measure Cobb angle and rotation degree of the apical vertebra. Correlation and linear regression were used to analyze the correlation between the Cobb angle and the rotation degree of the apical vertebra on the X-ray plain radiographs obtained from the standing and supine positions.Of 94 ADS patients who met the inclusion criteria, 14 (15%) patients were male and 80 (85%) patients were female who ranged in age from 41 to 92 years with a mean of 67 years. The mean Cobb angle on the supine X-ray radiographs was 21 ± 10° versus 26 ± 12° on the standing X-ray radiographs, the difference being statistically significant (P < 0.01). The rotation angle of the apical vertebra in the supine and standing positions was 1.8 ± 0.7 and 1.9 ± 0.7, respectively, the difference being statistically significant (P < 0.05). Correlation analysis showed a strong correlation in Cobb angle between the supine and standing X-ray plain radiographs (r = 0.92, P < 0.01). The correlation coefficient of the rotation of

    Dynamic X-rays (DXR) are widely recognized as an effective method to detect lumbar instability (LI). They are usually performed with the patient in standing position (SDXR). In our opinion, standing position inhibits micromovements of the lumbar segment interested by the listhesis, thanks to paravertebral muscles antalgic contraction and augmented tone. We aim to demonstrate that DXR in recumbent position (RDXR), reducing the action of paravertebral muscles, can discover hypermovements not evidenced in SDXR. Between January 2011 and January 2013, we studied 200 consecutive patients with lumbar degenerative disease with MRI, SDXR, and RDXR. We aimed to find a correlation between low back or radicular pain and the presence of a spondylolisthesis not showed by the SDXR, but showed by the RDXR. We analysed 200 patients: of the 133 not pathologic in SDXR, 43 patients (32.3 %) showed an hypermovement in RDXR (p = 0.0001) without any significant correlation between hidden listhesis and age, sex, or level involved. The aim of our study is to determine whether in patients with lumbalgy without evidence of listhesis in SDXR, pain can be attributed to a faccettal syndrome or to a spondylolisthesis. Consequence of pain is augmented muscular tone of the paravertebral musculature, particularly in standing position. Augmented muscular tone tries to inhibit the pain generator, attempting to limit the slippage of the involved segment. In patients examined in RDXR, the tone of paravertebral musculature is reduced, showing the hidden spondylolisthesis. (orig.)

    lumbar X-ray film was divided into five grades, and then the appropriate treatment method was selected according to the classification, grading and specific circumstances of the lumbar spondylolisthesis patients. RESUTLS AND CONCLUSION:The strong fusion and internal fixation and the rigid connection between implants and vertebra are often used to stabilize the spine and correct deformities with high bone fusion rate, thus reducing pseudoarticulation formation. Dynamic fusion and internal fixation can distribute the load conduction of rigid internal fixation with elastic material or micro-devices, thus reducing stress shielding and adjacent segment stress concentration. Dynamic non-fusion and internal fixation can change the load transfer mode of spinal motion segment, inhibit spinal movement and prevent adjacent segment degeneration, in order to make the instable lumbar spine reach its normal activity characteristics, and achieve dynamic reconstruction of lumbar sequence. Lumbar isthmus defects directly repaired with graft is suitable for the young adult with the symptoms of lumbar spondylolisthesis and without degenerative disc disease. There is no consistent option on which materials and position is suitable for graft in the lumbar spondylolisthesis patients, as wel as which methods for fusion and implant internal fixation can achieve ideal effect.

In 53.5% (n = 15 of the patients, snugly fitted local bone chips were used while in 46.4% (n = 13 of the patients, cage was used. Among the cage group, titanium cage was used in nine (32.1% and PEEK cages were used in four (14.2% patients. In one patient, a unilateral PEEK cage was used. The mean follow-up period was 24 months. Among the 28 patients, 67.8% (n = 19 were females and 32.14% (n = 9 were males. 68.24% (n = 18 had L4/L5 and 35.71% (n = 10 had L5/S1 spondylolisthesis. 39.28% (n = 11 were of grade I and 60.71% (n = 17 were of grade II spondylolisthesis. Conclusions: There was a statistically significant correlation (P < 0.012 and P < 0.027 between the change in disc height achieved and the improvement in VAS score in both the graft group and the cage group. The increment in disc height and VAS score was significantly better in the cage group (2 mm ± SD vis-a-vis 7.2 [88%] than the graft group (1.2 mm ± SD vis-a-vis 5 [62 %].

    Attention is drawn to the mode of development of spondylolysis/spondylolisthesis and to the fact that the articular processes of the small vertebrae can exercise an action on the pars interarticularis only if the latter are in oblique position. It is pointed out that the requisite obliqueness of the pars interarticularis is only possible in conjunction with lordosis, so that the latter is an essential condition for the pathogenesis of spondylolysis/spondylolisthesis. It is also pointed out that excessive load due to upright position of the subject is the triggering factor for spondylolysis/spondylolisthesis, because it is only from this position that the articular processes of the small vertebrae can exercise an action on the pars interarticularis.

    Danielson, B.; Frennered, K.; Selvik, G.; Irstam, L.

    Different degrees of artificial L5-S1 spondylolisthesis were created using a lumbar specimen. Lateral radiographs were obtained of each, with the specimen tilted and/or rotated. The true spondylolisthesis was determined stereophotogrammetrically. The slip, measured on the radiographs, was calculated according to two methods modified from BOXALL et coll. (2). No significant difference in accuracy was found between these two methods. The difference in calculated slip between examinations needs to be at least 20 per cent of the sagittal length of L5 to be regarded as a true progression. A true progress of slip of less than 20 per cent is difficult to detect with statistical certainty.

    Purpose: To describe the particular disc displacement pattern seen at MRI in patients with spondylolisthesis, and its potential contribution to foraminal stenosis. Methods: 38 patients with symptomatic lumbar anterior spondylolisthesis and 38 sex and aged matched control patients with herniated disc disease, at corresponding disc space levels, were included for study. In each case note was made of the presence, absence and direction of disc displacement and also the presence and location of neural contact with the displaced disc. Results: In 33 of 38 (86.8%) patients in the spondylolisthesis group, the vertical disc displacement was upward. In the control group only 3 patients (7.8%) had upward vertical disc displacement. 19 patients (53%) from the spondylolisthesis group had exit foraminal nerve root contact, compared to 7 patients (18.4%) from the control group. 27 control patients (71%) had contact within the lateral recess, compared to only 6 patients (17%) with spondylolisthesis. Differences for upward displacement were significant (p < 0.05). Conclusion: Disc displacement in patients with spondylolisthesis is predominately in a cephalad and lateral direction. Although this disc displacement pattern can occur in patients without spondylolisthesis, its incidence is much greater in the subset of patients with concomitant spondylolisthesis. In the setting of acquired osseous narrowing of the exit foramen, this described pattern of disc displacement superiorly and laterally in spondylolisthesis increases the susceptibility of spondylolisthesis patients to radicular symptoms and accounts for the exiting nerve root being more commonly affected than the traversing nerve root.

    The clinical advantages of reducing spondylolisthesis over fusion in situ have several intuitive reasons such as restore the spinal column into a more anatomic relationship and alignment. However, there is only little evidence in the literature supporting the theoretical advantages of reduction, and its effect on spinopelvic alignment remains poorly defined. In this study, a comprehensive finite element model was developed to analyze the biomechanics of the spine after spinal fusion at L5-S1 in both types of high-grade spondylolisthesis (balanced and unbalanced pelvis). The relevant clinical indices (i.e. spondylolisthesis grade and Dubousset lumbosacral angle), the displacement of L4-L5, pressure within the annulus and nucleus, and stress at L4-L5 were evaluated and compared. The model can well predict the changes of the important clinical indices during the surgery. For a balanced pelvis, the reduction has a minimal effect on the biomechanical conditions at the adjacent level during postsurgical activities. In the unbalanced case, reduction induced larger deformation in the lumbosacral region and a higher stress concentration at adjacent level. Whether such a stress concentration can lead to long-term disc degeneration is not known. The results provide additional information for the clinician considering reduction of high-grade spondylolisthesis.

    Industry sponsorship of clinical research of degenerative diseases of the spine has been associated with excessive positive published results as compared to research carried out without industry funding. We sought the rates of publication of clinical trials of degenerative diseases of the spine based on funding source as a possible explanation for this phenomenon. We reviewed all clinical trials registered at clinicaltrials.gov relating to degenerative diseases of the spine as categorized under six medical subject heading terms (spinal stenosis, spondylolisthesis, spondylolysis, spondylosis, failed back surgery syndrome, intervertebral disc degeneration) and with statuses of completed or terminated. These collected studies were categorized as having, or not having, industry funding. Published results for these studies were then sought within the clinicaltrials.gov database itself, PubMed and Google Scholar. One hundred sixty-one clinical trials met these criteria. One hundred nineteen of these trials had industry funding and 42 did not. Of those with industry funding, 45 (37.8%) had identifiable results. Of those without industry funding, 17 (40.5%) had identifiable results. There was no difference in the rates of publication of results from clinical trials of degenerative diseases of the spine no matter the funding source.

    Full Text Available One of the chronic progressive disorders of the spinal cord in dogs is the degenerative myelopathy (DM. The most predisposed age in dog is 5 to 14 years, while rarely noted in younger, there is no gender predisposition. This disorder most commonly appears in dogs of the German shepherd breed, but it can appear in other breeds too. The main changes about this disease are degeneration of the myelin, especially in the thoracic-lumbar segments of the spinal cord and the dorsal nerve roots. The progression of the disease is slow and can last months to years. Undoubtedly, diagnosis is made by examinations of the CSF and establishing elevated level of protein segments.

    Full Text Available Osteoarthritis, a degenerative joint disease, is the most commonrheumatic disorder mainly in a geriatric population. Manifestationsare pain, stiffness and functional loss in the affected joint.According to etiology it is classifi ed as primary (or idiopathicand secondary. Some risk factors for disease development aregenetics, race, age, sex, obesity, occupational activities andarticular biomechanics. Pathogenesis is the same for any cause orlocalization, being catabolic alterations, with synthesis, inhibitionand reparing intent of the cartilage matrix. Metalloproteinases andcytokines (IL-1,IL-6,TNF-α actions promote infl ammatory reactionand cartilage degradation. Pain, the most important symptom,does not correlate with radiologic fi ndings. Peripheral osteoarthritisoccurs predominantly in the knee, hip and hand. Diagnosis is basedon clinical features, laboratorial tests and radiological changes.Rheumatological associations’ guidelines for treatment includenon-pharmacologic (education, physiotherapy, assistive devices,and pharmacologic (analgesics, anti-infl ammatory drugs therapyand surgery. Arthroplasty seems to work better than medicines, butshould be used if other treatments have failed.

    Full Text Available Degenerative disease of the lumbar spine is common in ageing populations. It causes disturbing back pain, radicular symptoms and lowers the quality of life. We will focus our discussion on the surgical options of posterior lumbar interbody fusion (PLIF and transforaminal lumbar interbody fusion (TLIF and minimally invasive transforaminal lumbar interbody fusion (MI-TLIF for lumbar degenerative spinal deformities, which include symptomatic spondylolisthesis and degenerative scoliosis. Through a description of each procedure, we hope to illustrate the potential benefits of TLIF over PLIF. In a retrospective study of 53 ALIF/PLIF patients and 111 TLIF patients we found reduced risk of vessel and nerve injury in TLIF patients due to less exposure of these structures, shortened operative time and reduced intra-operative bleeding. These advantages could be translated to shortened hospital stay, faster recovery period and earlier return to work. The disadvantages of TLIF such as incomplete intervertebral disc and vertebral end-plate removal and potential occult injury to exiting nerve root when under experienced hands are rare. Hence TLIF remains the mainstay of treatment in degenerative deformities of the lumbar spine. However, TLIF being a unilateral transforaminal approach, is unable to decompress the opposite nerve root. This may require contralateral laminotomy, which is a fairly simple procedure.The use of minimally invasive transforaminal lumbar interbody fusion (MI-TLIF to treat degenerative lumbar spinal deformity is still in its early stages. Although the initial results appear promising, it remains a difficult operative procedure to master with a steep learning curve. In a recent study comparing 29 MI-TLIF patients and 29 open TLIF, MI-TLIF was associated with longer operative time, less blood loss, shorter hospital stay, with no difference in SF-36 scores at six months and two years. Whether it can replace traditional TLIF as the surgery of

    Retrospective analysis of the spino-pelvic alignment in a population of 85 patients with a lumbar degenerative disease. Several previous publications reported the analysis of spino-pelvic alignment in the normal and low back pain population. Data suggested that patients with lumbar diseases have variations of sagittal alignment such as less distal lordosis, more proximal lumbar lordosis and a more vertical sacrum. Nevertheless most of these variations have been reported without reference to the pelvis shape which is well-known to strongly influence spino-pelvic alignment. The objective of this study was to analyse spino-pelvic parameters, including pelvis shape, in a population of 85 patients with a lumbar degenerative disease and compare these patients with a control group of normal volunteers. We analysed three different lumbar degenerative diseases: disc herniation (DH), n = 25; degenerative disc disease (DDD), n = 32; degenerative spondylolisthesis (DSPL), n = 28. Spino-pelvic alignment was analysed pre-operatively on full spine radiographs. Spino-pelvic parameters were measured as following: pelvic incidence, sacral slope, pelvic tilt, lumbar lordosis, thoracic kyphosis, spino-sacral angle and positioning of C7 plumb line. For each group of patients the sagittal profile was compared with a control population of 154 asymptomatic adults that was the subject of a previous study. In order to understand variations of spino-pelvic parameters in the patients' population a stratification (matching) according to the pelvic incidence was done between the control group and each group of patients. Concerning first the pelvis shape, patients with DH and those with DDD demonstrated to have a mean pelvic incidence equal to 49.8 degrees and 51.6 degrees, respectively, versus 52 degrees for the control group (no significant difference). Only young patients, less than 45 years old, with a disc disease (DH or DDD) demonstrated to have a pelvic incidence significantly lower (48

    Full Text Available Abstract Background A classification of lumbosacral spondylolisthesis has been proposed recently. This classification describes eight distinct types of spondylolisthesis based on the slip grade, the degree of dysplasia, and the sagittal sacro-pelvic balance. The objectives of this study are to assess the reliability of this classification and to propose a new and refined classification. Methods Standing posteroanterior and lateral radiographs of the spine and pelvis of 40 subjects (22 low-grade, 18 high-grade with lumbosacral spondylolisthesis were reviewed twice by six spine surgeons. Each radiograph was classified based on the slip grade, the degree of dysplasia, and the sagittal sacro-pelvic balance. No measurements from the radiographs were allowed. Intra- and inter-observer reliability was assessed using kappa coefficients. A refined classification is proposed based on the reliability study. Results All eight types of spondylolisthesis described in the original classification were identified. Overall intra- and inter-observer agreement was respectively 76.7% (kappa: 0.72 and 57.0% (kappa: 0.49. The specific intra-observer agreement was 97.1% (kappa: 0.94, 85.0% (kappa: 0.69 and 88.8% (kappa: 0.85 with respect to the slip grade, the degree of dysplasia, and the sacro-pelvic balance, respectively. The specific inter-observer agreement was 95.2% (kappa: 0.90, 72.2% (kappa: 0.43 and 77.2% (kappa: 0.69 with respect to the slip grade, the degree of dysplasia, and the sacro-pelvic balance, respectively. Conclusion This study confirmed that surgeons can classify radiographic findings into all eight types of spondylolisthesis. The intra-observer reliability was substantial, while the inter-observer reliability was moderate mainly due to the difficulty in distinguishing between low- and high-dysplasia. A refined classification excluding the assessment of dysplasia, while incorporating the assessment of the slip grade, sacro-pelvic balance and global

    Congenital hypoplasia of the spinal pedicle is a rare condition. Previously reported cases were treated conservatively or with posterior instrumented fusion. However, the absence or hypoplasia of the lumbar pedicle may increase the difficulty of pedicle screw fixation and fusion. Herein, the authors describe 2 cases of rare adult congenital hypoplasia of the right lumbar pedicles associated with spondylolisthesis. The patients underwent anterior lumbar interbody fusion with a stand-alone cage as well as percutaneous pedicle screw fixation. This method was used to avoid the difficulties associated with pedicle screw fixation and to attain solid fusion. Both patients achieved satisfactory outcomes after a minimum of 2 years of follow-up. This method may be an alternative for patients with congenital hypoplasia of the lumbar spinal pedicle.

    Treatment of motor symptoms of degenerative cerebellar ataxia remains difficult. Yet there are recent developments that are likely to lead to significant improvements in the future. Most desirable would be a causative treatment of the underlying cerebellar disease. This is currently available only for a very small subset of cerebellar ataxias with known metabolic dysfunction. However, increasing knowledge of the pathophysiology of hereditary ataxia should lead to an increasing number of medically sensible drug trials. In this paper, data from recent drug trials in patients with recessive and dominant cerebellar ataxias will be summarized. There is consensus that up to date, no medication has been proven effective. Aminopyridines and acetazolamide are the only exception, which are beneficial in patients with episodic ataxia type 2. Aminopyridines are also effective in a subset of patients presenting with downbeat nystagmus. As such, all authors agreed that the mainstays of treatment of degenerative cerebellar ataxia are currently physiotherapy, occupational therapy, and speech therapy. For many years, well-controlled rehabilitation studies in patients with cerebellar ataxia were lacking. Data of recently published studies show that coordinative training improves motor function in both adult and juvenile patients with cerebellar degeneration. Given the well-known contribution of the cerebellum to motor learning, possible mechanisms underlying improvement will be outlined. There is consensus that evidence-based guidelines for the physiotherapy of degenerative cerebellar ataxia need to be developed. Future developments in physiotherapeutical interventions will be discussed including application of non-invasive brain stimulation. PMID:24222635

    The measure of radiographic pelvic and spinal parameters for sagittal balance analysis has gained importance in reconstructive surgery of the spine and particularly in degenerative spinal diseases (DSD). Fusion in the lumbar spine may result in loss of lumbar lordosis (LL), with possible compensatory mechanisms: decreased sacral slope (SS), increased pelvic tilt (PT) and decreased thoracic kyphosis (TK). An increase in PT after surgery is correlated with postoperative back pain. A decreased SS and/or abnormal sagittal vertical axis (SVA) after fusion have a higher risk of adjacent segment degeneration. High pelvic incidence (PI) increases the risk of sagittal imbalance after spine fusion and is a predictive factor for degenerative spondylolisthesis. Restoration of a normal PT after surgery is correlated with good clinical outcome. Therefore, there is a need for comparative prospective studies that include pre- and postoperative spinopelvic parameters and compare complication rate, degree of disability, pain and quality of life.

    Full Text Available Pycnodysostosis is a skeletal dysplasia, which is mainly characterized by short stature, increased bone density, separated cranial sutures with open fontanel, bone fragility, small hands and feets. We present a female patient, with pycnodysostosis has been misdiagnosed as rickets for a long period. Patient also had spondylolysis and spondylolisthesis at L5 vertebra. Patient was undergone the external fixation and patient were spent external fixation surgery due to spondylolysis and spondylolisthesis at L4-5 level and right femoral neck fracture. In conclusion, genetical skeletal dysplasia such as pycnodysostosis should be considered out of rickets if exists short stature, bone fragility and open fontanel. In patient with pycnodysostosis occurs bone fragility at an earlier age appears despite the increase in bone mineral density. Also, the development of spondylolysis and isthmic type of spondylolisthesis as well as bone fragility must be considered in the pycnodysostosis. Therefore, we emphasize to prevent high-impact trauma such as falling and crash in patients with pycnodysostosis. (Turkish Journal of Osteoporosis 2011;17:26-9

    Full Text Available ABSTRACT Objectives: To demonstrate the recovery of lumbar sagittal pelvic alignment and sagittal pelvic balance after surgical reduction of lumbar spondylolisthesis and establish the benefits of the surgery for reduction and fixation of the lumbar spondylolisthesis with 360o circumferential arthrodesis for 2 surgical approaches by clinical and functional evaluation. Method: Eight patients with lumbar spondylolisthesis treated with surgical reduction and fixation of listhesis and segmental circumferential fusion with two surgical approaches were reviewed. They were evaluated before and after treatment with Oswestry, Visual Analogue for pain and Odom scales, performing radiographic measurement of lumbar sagittal alignment and pelvic sagittal balance with the technique of pelvic radius. Results: Oswestry scales and EVA reported improvement of symptoms after treatment in 8 cases; the Odom scale had six outstanding cases reported. The lumbar sagittal alignment presented a lumbosacral lordosis angle and a lumbopelvic lordosis angle reduced in 4 cases and increased in 4 other cases; pelvic sagittal balance increased the pelvic angle in 4 cases and decreased in 3 cases and the sacral translation of the hip axis to the promontory increased in 6 cases. Conclusion: The surgical procedure evaluated proved to be useful by modifying the lumbar sagittal alignment and the pelvic balance, besides reducing the symptoms, enabling the patient to have mobility and movement and the consequent satisfaction with the surgery.

Minimally invasive techniques have several advantages over the open traditional techniques: less blood loss, preservation of spine muscle integrity, shorter hospitalization, early mobilization, reduced pain levels, lower risk of infection. The presented cases cover following lumbar pathologies: segmental spinal instability, LV-SI grade II. spondylolisthesis, degenerative spondylolisthesis, spine trauma. Unilateral or bilateral mini-open technique was employed in the degenerative cases, depending on symptoms and signes. If unilateral symptoms--pathology was identified, screws and rod were implanted percutaneously on the side contralateral to the pathology. The segmental fusion between vertebral bodies was always assured by a cage and autologous bone. The presented trauma case involved combined AO type A2 and B fractures. The anterior column was strengthened with vertebral body stents filled with bone cement, the posterior column was fixed with a percutaneously implanted screw rod system. Insertion of stents in the collapsed vertebra significantly increased the vertebral body height and also improved the stability of the spine. Minimally invasive spine surgery techniques appear more advantageous over the traditional open spine surgery that necessitates for large midline approaches.

    Spondylolisthesis is a pathological condition caused by the slipping of a vertebral body, compared to the underlying structure, following structural and/or degenerative changes to the spine. Studies have attempted evidence to the connection between the natural history of spondylolisthesis, the degree and progression of the slip factor, as well as the pain and disability. Studies have reported a high level of heterogeneity of these factors in different patients as well as difficulty in predicting behaviour. It has been suggested that vertebral instability, independent of the slip factor, could be considered the most important factor to be treated conservatively or surgically. Furthermore, it appears that some patients may manifest complete disk degeneration over time, with vertebral bodies shifting closer and spontaneous stabilisation. This case study reports a forty-four-year old woman, with isthmic spondylolisthesis, where the spine surgeon recommended physiotherapy for conservative treatment, with a prognosis of possible spontaneous stabilization. The case was followed for six years, both clinically and radiologically. Treatment was based on a specific stabilising training program (motor control), immediately aimed to improve the disability and pain factors while waiting for a possible spontaneous stabilisation, that the latest radiological exams revealed with an attempt of arthrodesis. The Oswestry Disability Index (ODI) and the Roland Morris Disability Questionnaire (RMDQ) to measure disability, and the Numeric Rating Scale (NRS) to measure pain, were carried out at the beginning, during and at the end of treatment. They were compared with the radiographic material documenting the evolution of the spondylolisthesis over time. This case study appears to confirm that the hypothesis that a specific aimed approach of rehabilitation may improve the disability and pain levels without compromising the process of spontaneous arthrodesis. The evolution was documented

    Lumbar fusion for spondylolisthesis is associated with consistent outcomes in the general population. However, workers' compensation is a risk factor for worse outcomes. Few studies have evaluated prognostic factors within this clinically distinct population. The goal of this study was to identify prognostic factors for return to work among patients with workers' compensation claims after fusion for spondylolisthesis. The authors used International Classification of Diseases, Ninth Revision, and Current Procedural Terminology codes to identify 686 subjects from the Ohio Bureau of Workers' Compensation who underwent fusion for spondylolisthesis from 1993 to 2013. Positive return to work status was recorded in patients who returned to work within 2 years of fusion and remained working for longer than 6 months. The criteria for return to work were met by 29.9% (n=205) of subjects. The authors used multivariate logistic regression analysis to identify prognostic factors for return to work. Negative preoperative prognostic factors for postoperative return to work included: out of work for longer than 1 year before fusion (PReturn to work rates associated with these factors were 9.7%, 0.0%, 10.0%, 29.2%, and 25.0%, respectively. If these subjects were excluded, the return to work rate increased to 60.4%. The 70.1% (n=481) of subjects who did not return to work had markedly worse outcomes, shown by higher medical costs, chronic opioid dependence, and higher rates of failed back syndrome, total disability, and additional surgery. Psychiatric comorbidity increased after fusion but was much higher in those who did not return to work. Future studies are needed to identify how to better facilitate return to work among similar patients with workers' compensation claims.

    Spondylolisthesis associated with neurofibromatosis is rare, and only 12 cases have been reported so far. However, only one report of grade 4 spondylolisthesis with neurofibromatosis has been reported in the literature. A 15-year-old boy with neurofibromatosis was admitted for back pain and neurological claudication. Radiograph showed grade 4 spondylolisthesis of the L5 vertebra with scalloping of the L4-L5 vertebrae. L4-L5 laminectomy, reduction, L3-S1 posterior instrumentation and fusion were performed. The reduction of the spondylisthesis was done entirely from the posterior approach using pedicle screws. Radiography at four months showed a broken S1 screw with a loss of reduction. The patient was re-operated on, to provide additional stability with pelvic fixation. He was pain-free with a good fusion at the two-year follow-up. Adequate posterior stabilisation with fusion gives good results in grade 4 spondylolisthesis associated with neurofibromatosis and dural ectasia.

    Prospective validation of the Scoliosis Research Society Outcomes Questionnaire French-Canadian version (SRS-22fv) in adolescent patients with spondylolisthesis. To determine the measurement properties of the SRS-22fv. The SRS-22 is widely used for the assessment of health-related quality of life in adolescent idiopathic scoliosis (AIS) and other spinal deformities. Spondylolisthesis has an important effect on quality of life. The instrument was previously used in this population, although its measurement properties remained unknown. We aim to determine its reliability, factorial, concurrent validity, and its discriminant capacity in an adolescent spondylolisthesis population. The SRS-22fv was tested in 479 subjects (272 patients with spondylolisthesis, 143 with AIS, and 64 controls) at a single institution. Its reliability was measured using the coefficient of internal consistency, concurrent validity by the short form-12 (SF-12v2 French version) and discriminant validity using multivariate analysis of variance, analysis of covariance, and multivariate linear regression. The SRS-22fv showed a good global internal consistency (spondylolisthesis: Cronbach α = 0.91, AIS: 0.86, and controls: 0.78) in all its domains for spondylolisthesis patients. It showed a factorial structure consistent with the original questionnaire, with 60% of explained variance under four factors. Moderate to high correlation coefficients were found for specifically corresponding domains between SRS-22fv and SF-12v2. Boys had higher scores than do girls, scores worsened with increasing age and body mass index. Analysis of covariance showed statistically significant differences between patients with spondylolisthesis, patients with AIS, and controls when controlling for age, sex, body mass index, pain, function, and self-image scores. In the spondylolisthesis group, scores on all domains and mean total scores were significantly lower in surgical candidates and in patients with high

    Science.gov (United States)

    Rew, D A

    1998-10-01

    Cancer is primarily a disease of ageing epithelia, and of ageing individuals. We now possess detailed insights into the changes in cell regulatory genes and DNA repair systems which accumulate with time and which manifest in malignancy. These demonstrate how cancer is frequently characterized by degenerative change in the genotype, from the most subtle base pair mutations to gross aneuploidy, and by deterioration in cell and tissue regulatory control, be it of proliferation, programmed cell death or signalling. Cancer may thus be as much a phenomenon of loss or deterioration of normal genomic control as of the acquisition of new, neoplastic functions. This distinction may be more than semantic, not least because it governs our approach to the search for therapeutic strategies. This essay considers the concept of cancer as a degenerative disease and its implications, and proposes the neologism aldoplasia to describe this phenomenon of cancer biology.

    Fifty-tree patients with localized painful spine syndrome were investigated prospectively by contrast-enhanced MRI. Pain was not predominantly radiating and there was no clinical evidence of spinal infection. In all patients, sagittal SE T1-weighted, fast-SE T2-weighted or turbo-STIR, and T1-weighted frequency-selective fat-suppressed images were obtained. We identified 37 vascularized disks in 26 patients. In 18 patients the changes had occurred spontaneously, in 6, the affected disk had been operated on previously, and 2 patients had spondylolisthesis. In 15 patients, vascularization was accompanied by medullary edema adjacent to the vertebral endplates. In one of the vascularized disks, herniation was also found. In seven patients, ventral diskectomy was performed. Histopathologic findings confirmed disk vascularization in six of seven cases. Degenerative, band-like disk vascularization is a feature which is associated with local pain. It is demonstrated by contrast-enhanced MRI. Degenerative disk vascularization is an important differential diagnosis to bacterial spondylodiskitis. It can be a cause of pain in patients with postdiskectomy syndrome. (orig./MG)

    Full Text Available Objective to develop current options of surgical treatment of L5-spondylolisthesis in children. Materials and methods: 48 patients were observed and underwent surgical treatment at age of 10-17 years. In 9 patients spondylolisthesis of L5 was grade 2, in 14 - grade 3, in 12 - grade 4. 9 patients had spondyloptosis of the body of L5-vertebra. The article presents different options of surgical treatment of spondylolisthesis in children depending on the degree of vertebrae body shift and the main clinical manifestations. During surgery the anatomy of the vertebral canal and the normal interposition in the pathological segment were reconstructed. It resulted in normalization of the body balance and regression of neurological symptoms. Results: in spondylolisthesis grade 2 and 3 full reduction was achieved. In patients with grade 4 spondylolisthesis deformity was reduced to grade 2-3. Pain and radicular syndromes regressed in 2-3 days after surgery. In patients with monoparesis and contractures regression of neurological deficit took 1-1,5 months. Conclusions: The method of surgical treatment in patients with spondylolisthesis of L5 vertebrae depends on the degree of vertebrae shifting presence of segmental instability and neurological sighns.

    Aim: To evaluate the differences in the lumbosacropelvic structure between normal individuals and those with pseudospondylolisthesis. Materials and methods: The renal stone protocol abdominal CT images of 452 patients were retrospectively analysed. Twenty individuals who had degenerative anterolisthesis at the L5-S1 level were included in the study. Moreover, a control group of individuals was formed, similar in age and gender to the study group. A number of linear and angular lumbosacral morphological parameters were evaluated using two- and three-dimensionally reformatted CT images. The data of the two groups were compared using the t-test and Mann-Whitney U-test. Results: There was an association between spondylolisthesis and decreased thickness of the transverse process (p = 0.01), the height of the iliac crest (p = 0.028), lumbar angle (p = 0.041), sacral table angle (p = 0.033), sacral table index (p = 0.0001), sacral kyphosis (p = 0.025), sacral slope (p = 0.007), and width of the transverse process (p = 0.038), and increased transverse articular dimension of the facet joint (p = 0.003), axial angle of the facet joint (p = 0.002), sagittal angle of the facet joint (p = 0.012), S1 vertebra interfacet index (p = 0.003), the distance between the L5 vertebral transverse process and the iliac crest (p = 0.003), pelvic incidence (p = 0.016), L5 vertebra posterior angle (p = 0.001), and intersacroiliac joint angle (p = 0.024). Conclusion: The lumbosacropelvic morphology in patients with degenerative spondylolisthesis is quite different from that of normal individuals. These abnormalities should be revealed using imaging methods as they can be defining for pseudospondylolisthesis development and have important effects on therapy planning.

  9. [Dysexecutive syndromes and degenerative diseases].

    Pillon, B; Czernecki, V; Dubois, B

    2004-04-01

    A dysexecutive syndrome is observed not only in frontotemporal lobar degeneration, but also in subcortical degenerative diseases, and even in Alzheimer's disease whose lesions predominate in temporoparietal associative areas. The association between a dysexecutive syndrome and various cerebral localisations may be explained by the fact that cognitive and behavioral organisation recruits anatomofunctional frontostriatal and frontoparietal circuits. Both animal experimentation and human clinical observation argue in favour of a functional continuity and complementarity among these loops. The prefrontal cortex would be particularly needed in new situations, to inhibit old programs of action not adapted to the present context and to elaborate new ones; the basal ganglia would be rather required by the repetition of the situation to progressively transform the new program in routine. If we refer to Shallice model, we can hypothesize that optimal executive functions require the preservation not only of the Supervisory Attentional System, mainly dependent on the prefrontal cortex, but also of the Contention Scheduling, recruiting the basal ganglia, and of the Schemas of Action, represented in parietal and premotor areas. Therefore, the neuropsychological assessment of patients with degenerative diseases contributes to the understanding of the anatomofunctional architecture of executive functions.

    Cerebellar syndromes result in distinct clinical symptoms, such as ataxia, dysarthria, dysmetria, intention tremor and eye movement disorders. In addition to the medical history and clinical examination, imaging is particularly important to differentiate other diseases, such as hydrocephalus and multi-infarct dementia from degenerative cerebellar diseases. Degenerative diseases with cerebellar involvement include Parkinson's disease, multiple system atrophy as well as other diseases including spinocerebellar ataxia. In addition to magnetic resonance imaging (MRI), nuclear medicine imaging investigations are also helpful for the differentiation. Axial fluid-attenuated inversion recovery (FLAIR) and T2-weighted sequences can sometimes show a signal increase in the pons as a sign of degeneration of pontine neurons and transverse fibers in the basilar part of the pons. The imaging is particularly necessary to exclude other diseases, such as normal pressure hydrocephalus (NPH), multi-infarct dementia and cerebellar lesions. (orig.)

    Radcliff, Kristen E; Jakoi, Andre M

    2015-04-01

    To the authors' knowledge, this is the first article to present a pedicle subtraction osteotomy in the lumbar spine to correct and stabilize a high-grade isthmic spondylolisthesis, which poses many challenges with regard to treatment options and outcomes. The optimal surgical treatment for high-grade spondylolisthesis is controversial, but the goals of treatment are to stabilize the affected spinal levels and to decompress the neural elements. A pedicle subtraction osteotomy is a reconstructive procedure that addresses fixed sagittal imbalance by increasing lumbar lordosis through posterior spinal column shortening. The authors report a 46-year-old patient with chronic, progressively worsening back and leg radiculopathy accompanied by sagittal plane malalignment and for which a pedicle subtraction osteotomy was performed. The procedure yielded stabilization of the patient's lumbar spondylolisthesis and sagittal plane alignment was restoration. At 3 months postoperatively, the patient's pain had fully resolved and her motor and neurologic examination exhibited no deficits. At 24 months postoperatively, she was still symptom-free and ambulating without assistance. This report is the first documented successful pedicle subtraction osteotomy in the treatment of high-grade spondylolisthesis. This report indicates that certain patient populations may be amenable to pedicle subtraction osteotomy as a treatment option for pathology involving high-grade isthmic spondylolisthesis.

    The aim of this paper was to systematically review the diagnostic ability of clinical tests to detect lumbar spondylolysis and spondylolisthesis. A systematic literature search of six databases, with no language restrictions, from 1950 to 2014 was concluded on February 1, 2014. Clinical tests were required to be compared against imaging reference standards and report, or allow computation, of common diagnostic values. The systematic search yielded a total of 5164 articles with 57 retained for full-text examination, from which 4 met the full inclusion criteria for the review. Study heterogeneity precluded a meta-analysis of included studies. Fifteen different clinical tests were evaluated for their ability to diagnose lumbar spondylolisthesis and one test for its ability to diagnose lumbar spondylolysis. The one-legged hyperextension test demonstrated low to moderate sensitivity (50%-73%) and low specificity (17%-32%) to diagnose lumbar spondylolysis, while the lumbar spinous process palpation test was the optimal diagnostic test for lumbar spondylolisthesis; returning high specificity (87%-100%) and moderate to high sensitivity (60-88) values. Lumbar spondylolysis and spondylolisthesis are identifiable causes of LBP in athletes. There appears to be utility to lumbar spinous process palpation for the diagnosis of lumbar spondylolisthesis, however the one-legged hyperextension test has virtually no value in diagnosing patients with spondylolysis.

    Development of anesthesiology and improvement of surgical instruments enabled aggressive surgical treatment even in elderly patients, who require more active physical activities than they were in the past. However, there are controversies about the clinical outcome of spinal surgery in elderly patients with spinal stenosis or spondylolisthesis. The purpose of this study is to review the clinical outcome of spinal surgery in elderly patients with spinal stenosis or spondylolisthesis. MEDLINE search on English-language articles was performed. There were 39685 articles from 1967 to 2013 regarding spinal disease, among which 70 dealt with geriatric lumbar surgery. Eighteen out of 70 articles dealt with geriatric lumbar surgery under the diagnosis of spinal stenosis or spondylolisthesis. One was non-randomized prospective, and other seventeen reports were retrospective. One non-randomized prospective and twelve out of seventeen retrospective studies showed that old ages did not affect the clinical outcomes. One non-randomized prospective and ten of seventeen retrospective studies elucidated postoperative complications: some reports showed that postoperative complications increased in elderly patients, whereas the other reports showed that they did not increase. Nevertheless, most complications were minor. There were two retrospective studies regarding the mortality. Mortality which was unrelated to surgical procedure increased, but surgical procedure-related mortality did not increase. Surgery as a treatment option in the elderly patients with the spinal stenosis or spondylolisthesis may be reasonable. However, there is insufficient evidence to make strong recommendations regarding spinal surgery for geriatric patients with spinal stenosis and spondylolisthesis.

    Osteogenesis imperfecta is a heritable group of collagen-related disorders that affects up to 50,000 people in the United States. Although the disease is most symptomatic in childhood, adults with osteogenesis imperfecta also are affected by the sequelae of the disease. Orthopaedic manifestations include posttraumatic and accelerated degenerative joint disease, kyphoscoliosis, and spondylolisthesis. Other manifestations of abnormal collagen include brittle dentition, hearing loss, cardiac valve abnormalities, and basilar invagination. In general, nonsurgical treatment is preferred for management of acute fractures. High rates of malunion, nonunion, and subsequent deformity have been reported with both closed and open treatment. When surgery is necessary, surgeons should opt for load-sharing intramedullary devices that span the entire length of the bone; locking plates and excessively rigid fixation generally should be avoided. Arthroplasty may be considered for active patients, but the procedure frequently is associated with complications in this patient population. Underlying deformities, such as malunion, bowing, rotational malalignment, coxa vara, and acetabular protrusio, pose specific surgical challenges and underscore the importance of preoperative planning.

    Full Text Available Objective - to compare results of spondylolisthesis treatment using different surgical technologies. Material and methods: 84 patients (aged from 19 till 67 with spondylolisthesis of 1-3 degree (H.W Meyerding were operated. Two methods of surgical exposures were used for decompression and stabilization. Anterior decompression and stabilization exposures from retroperitoneal access were used for the first group of patients. The second group was operated using posteriolateral interbody fusion with transpedicular screw fixation. The following results were estimated after operation: the level of patients’ postoperative adaptation period and the rate of neurological and orthopedic rehabilitation during the postoperative period. Conclusions. The obtained functional results show no difference for both groups where posterior and anterior exposures were used for spondylolisthesis surgical treatment of 1-3 degree.

    Seventeen patients with sciatica and isthmic lumbar spondylolisthesis were studied with magnetic resonance (MR) imaging. In 13, myelography was also performed: 5 had dural sac deformation and root sleeve shortening, 2 had deformation with unilateral root sleeve shortening, one had bilateral root sleeve shortening only, and one had sac deformation only. In 4, myelography was normal. On sagittal MR examinations the neural foramen had an altered shape bilaterally with the long axis horizontal in all cases. In addition to altered shape the following was found in the 33 foramina evaluated. I: Normal nerve (n=8), II: Compressed nerve (n=16); III: Disappearance of fat, nerve not possible to identify (n=9). In patients with unilateral sciatica, the degree of foraminal stenosis correlated well with the side of symptoms. Coronal views showed the course of the nerve and pedicular kinking. Eight patients underwent decompressive surgery which revealed nerve compression by hypertrophic fibrous tissue and pedicular kinking, which correlated well with the findings on MR. Since the site of nerve compression often was peripheral to the root sleeves, myelography did not give complete information. (orig.).

    Full Text Available Objective. The authors present the clinical results obtained in patients who underwent interspinous fusion device (IFD implantation following posterior lumbar interbody fusion (PLIF. The purpose of this study is investigating the feasibility of IFD with PLIF in the treatment of lumbar spondylolisthesis. Methods. Between September 2013 and November 2014, 39 patients underwent PLIF and subsequent IFD (Romeo®2 PAD, Spineart, Geneva, Switzerland implantation. Medical records of these patients were retrospectively reviewed to collect relevant data such as blood loss, operative time, and length of hospital stay. Radiographs and clinical outcome were evaluated 6 weeks and 12 months after surgery. Results. All 39 patients were followed up for more than one year. There were no major complications such as dura tear, nerve injuries, cerebrospinal fluid leakage, or deep infection. Both interbody and interspinous fusion could be observed on radiographs one year after surgery. However, there were 5 patients having early retropulsion of interbody fusion devices. Conclusion. The interspinous fusion device appears to achieve posterior fixation and facilitate lumbar fusion in selected patients. However, further study is mandatory for proposing a novel anatomic and radiological scoring system to identify patients suitable for this treatment modality and prevent postoperative complications.

    We report a case of rare cervical isthmic spondylolisthesis of C6-7 combined occult spinal bifida at C6, and review the radiologic finding, different diagnosis and treatment. A 23-year old female presented nuchal, back pain after traffic accident. Radiologic finding showed the 6(th) cervical isthmic defect, spondylolisthesis and dysplasia. The patient was conservatively treated about 8 weeks, and 10 months after injury, she was symptom free with full range of motion of cervical spine and she was followed up. Cervical spondylolysis is a very rare condition. This clinical importance is vulnerable to trauma. For whatever reasons, symptomatic patients need to be treated by conservative or surgical option.

    Stereotypies are simple or complex involuntary/unvoluntary behaviors, common in fronto-temporal dementia (FTD), but not studied in other types of degenerative dementias. The aim was to investigate stereotypy frequency and type in patients with FTD, Alzheimer's disease (AD), progressive supranuclear palsy (PSP) and Parkinson's disease with dementia (PDD) in a multicenter observational study; and to investigate the relation of stereotypies to cognitive, behavioral and motor impairment. One hundred fifty-five consecutive outpatients (45 AD, 40 FTD, 35 PSP and 35 PDD) were studied in four hospitals in northern Italy. Stereotypies were examined by the five-domain Stereotypy Rating Inventory. Cognition was examined by the Mini Mental State and Frontal Assessment Battery, neuropsychiatric symptoms by the Neuropsychiatric Inventory, and motor impairment and invalidity by the Unified Parkinson's Disease Rating Scale part III, and activities of daily living. Stereotypies were present in all groups. FTD and PDD had the greatest frequency of one-domain stereotypies; FTD also had the greatest frequency of two-or-more domain stereotypies; movement stereotypies were the most common stereotypies in all groups. AD patients had fewer stereotypies than the other groups. Stereotypies are not exclusive to FTD, but are also fairly common in PSP and PDD, though less so in AD. Stereotypies may be underpinned by dysfunctional striato-frontal circuits, known to be damaged in PSP and PDD, as well as FTD.

    Lumbar degenerative kyphosis (LDK) is a subgroup of the flat-back syndrome and is most commonly caused by unique life styles, such as a prolonged crouched posture during agricultural work and performing activities of daily living on the floor. Unfortunately, LDK has been used as a byword for degenerative sagittal imbalance, and this sometimes causes confusion. The aim of this review was to evaluate the exact territory of LDK, and to introduce another appropriate term for degenerative sagittal...

    The goal of surgical treatment for degenerative lumbar spinal stenosis (LSS) is to effectively relieve the neural structures by various decompressive techniques. Microendoscopic decompressive laminotomy (MEDL) is an attractive option because of its minimally invasive nature. The aim of prospective study was to investigate the effectiveness of MEDL by evaluating the clinical outcomes with patient-oriented scoring systems. Sixty consecutive patients receiving MEDL between December 2005 and April 2007 were enrolled. The indications of surgery were moderate to severe stenosis, persistent neurological symptoms, and failure of conservative treatment. The patients with mechanical back pain, more than grade I spondylolisthesis, or radiographic signs of instability were not included. A total of 53 patients (36 women and 17 men, mean age 62.0) were included. Forty-five patients (84.9%) were satisfied with the treatment result after a follow-up period of 15.7 months (12-24). The clinical outcomes were evaluated with the Oswestry disability index (ODI) and the Japanese Orthopedic Association (JOA) score. Of the 50 patients providing sufficient data for analysis, the ODI improved from 64.3 +/- 20.0 to 16.7 +/- 20.0. The JOA score improved from 9.4 +/- 6.1 to 24.2 +/- 6.0. The improvement rate was 73.9 +/- 30.7% and 40 patients (80%) had good or excellent results. There were 11 surgical complications: dural tear in 5, wrong level operation in 2, and transient neuralgia in 4 patients. No wound-related complication was noted. Although the prevalence of pre-operative comorbidities was very high (69.8%), there was no serious medical complication. There was no post-operative instability at the operated segment as evaluated with dynamic radiographs at final follow-up. We concluded that MEDL is a safe and very effective minimally invasive technique for degenerative LSS. With an appropriate patient selection, the risk of post-operative instability is minimal.

    Background: Transverse fractures of the sacrum are rare, and surgical treatment for these fractures ranges from conservative to challenging. Transverse stress fractures of the sacrum after placement of lumbar-to-sacral instrumentation have been previously described. We report a new technique to repair a transverse Type-2 Roy-Camille fracture with spondylolisthesis of S1 over S2 in a previously fused instrumented high-grade L4-L5, L5-S1 spondylolisthesis. Case Description: A 64-year-old female who previously had an L4-L5, L5-S1 fusion for spondylolisthesis presented with excruciating lower back pain and radiculopathy for over 6 months. She was found to have an S1-S2 transverse fracture caused by previous implantation of pedicle screws. She underwent repositioning of several failed right lumbar and sacral screws and then had bilateral S1-S2 screws placed directly across the fracture line. The patient had an unremarkable postoperative course. She discontinued most of her pain medications within 6 weeks postoperatively. In the months following surgery, she reported only minimal lower back pain and no radiculopathy with the last appointment 5 years postoperatively. Conclusions: We describe a novel technique to reduce an iatrogenic transverse type-2 Roy-Camille fracture at S1-S2 in a previously instrumented high-grade L4-L5, L5-S1 spondylolisthesis. The patient's fracture achieved adequate reduction and fusion with symptomatic relief. PMID:28028448

    Conclusions: Regarding patients receiving interspinous devices for symptomatic lumbar spinal stenosis, several high-quality studies have failed to demonstrate a statistical difference in outcomes between patients with or without Grade 1 spondylolisthesis. Nevertheless, surgeons should have a high degree of suspicion when considering use of interspinous devices in this patient population.

    Artificial neural networks have found applications in various areas of medical diagnosis. The capability of neural networks to learn medical data, mining useful and complex relationships that exist between attributes has earned it a major domain in decision support systems. This paper proposes a fast automatic system for the diagnosis of disk hernia and spondylolisthesis using biomechanical features and neural network. Such systems as described within this work allow the diagnosis of new cases using trained neural networks; patients are classified as either having disk hernia, spondylolisthesis, or normal. Generally, both disk hernia and spondylolisthesis present similar symptoms; hence, diagnosis is prone to inter-misclassification error. This work is significant in that the proposed systems are capable of making fast decisions on such somewhat difficult diagnoses with reasonable accuracies. Feedforward neural network and radial basis function networks are trained on data obtained from a public database. The results obtained within this research are promising and show that neural networks can find applications as efficient and effective expert systems for the diagnosis of disk hernia and spondylolisthesis.

    In spondylolisthesis with an indication for fusion and with a slipping of more than 50% at least a partial reposition should be reached in general because the incidence of pseudarthrosis would increase with a fusion in situ and a large disturbance of the spinal statics would persist. Hereby with almost all methods an enlarged operative morbidity and often a longer fusion range has to be taken in account compared to the fusion in situ. Therefore, in smaller slippages the fusion in situ will be favoured because the disturbance of the statics is not so important, that such an effort combined with such methods is necessary. If the operation method with small spondylolisthesis and pseudospondylolisthesis allows the reposition without much effort and if the operative morbidity in comparison with the fusion in situ is not higher, then it is reasonable to fuse the cases with a spondylolisthesis Meyerding grade 1 and 2 in the anatomic corrected position too. Because the spinal fixator we use fills out these criteria we combine the correction of the position with the fusion also in cases of small spondylolisthesis. The incidence of neurologic complications correlates with the amount of the reposition distance and can be caused by preforaminal or extraforaminal lesions. The reduction of small malpositions could only produce preforaminal lesions. Using the spine fixator with its reposition instruments linked outside the wound and with it's un-inhibited access to the segment and to the preforaminal neural structures during the whole repositioning these lesions can be avoided.

    2006-01-01

    Full Text Available Introduction. Various clinical conditions can cause low back pain, and in most cases it is of a degenerative origin. Degenerative disc disease is a common condition which affects young to middle-aged men and women equally. Changes in the mechanical properties of the disc lead to degenerative arthritis in the intervertebral joints, osteophytes, and narrowing the intervertebral foramen or the spinal canal. Pathophysiology. Degenerative cascade, described by Kirkaldy-Willis, is the widely accepted pathophysiologic model describing the degenerative process as it affects the lumbar spine in 3 phases. Diagnosis. There are two forms of low back pain secondary to degenerative disc disease: a lumbalgia and b lumbar radiculopathy. Limitation of movement, problems with balance, pain, loss of reflexes in the extremities, muscle weakness, loss of sensation or other signs of neurological damage can be found on physical examination. For accurate diagnosis, it is often necessary to combine clinical examination and sophisticated technology. Treatment. Coservative treatment consists of rest, physical therapy, pharmacological therapy and injection therapy. Physical rehabilitation with active patient participation is a key approach to treatment of patients with discogenic pain. Physical therapy, occupational therapy and kinesitherapy are important for improving muscle strength, endurance, and flexibility. Disc surgery is performed if surgical intervention is required. .

    To analyse radiographic correlates for the clinical status of patients and the deformation reducibility of high-grade lumbosacral spondylolisthesis. We also clarify the clinical and radiographic correlates of a new parameter for S1 dystrophy, the ''S1 index''. One hundred cases of high-grade isthmic lumbosacral spondylolisthesis were reviewed. We noted the dystrophic changes in the cranial sacral endplate, and the caudal endplate of L5. The severity of the spondylolisthesis was evaluated by measuring the lumbosacral kyphosis. The clinical status and the deformation reducibility (dependent on the stiffness of the deformation) were compared with these dystrophic patterns, the sagittal slope of S1 and S2 endplates and a sacral morphological marker, the S1 index. Lumbosacral kyphosis was less severe in cases with dystrophic changes of the posterior cranial edge of S1 and/or of the posterior caudal edge of L5 but its reducibility was worse. These patients were more functionally impaired. We describe and analyse this situation as a partial lumbosacral disc failure responsible for the less severe L5 slipping. The S1 index was strongly correlated with the grade of slipping, the lumbosacral kyphosis and its reducibility. We noted the same configuration among patients with a smaller S1 index, i.e. vertical S1 and S2 vertebral bodies associated with more severe but more reducible lumbosacral kyphosis. Analysing specific criteria, we think it is possible to note progressive dystrophic changes according to the natural history of lumbosacral spondylolisthesis. We think that repeated measurements of these morphological parameters in patients diagnosed with a low-grade lumbosacral spondylolisthesis could be helpful in the early detection of evolving lumbosacral kyphosis and L5 slipping.

    To assess the clinical potential and limitations of magnetic resonance imaging (MRI) in degenerative lumbar spinal diseases, the findings of MR imaging were compared with those of myelography and CT. The subjects were 80 patients with intervertebral disc herniation (46), spondylosis (28), degenerative spondylolisthesis (5), and spondylolysis (one). There was a good correlation between sagittal MRI (T1-weighted images) and myelography in measuring the anteroposterior diameter and the compression rate of the injured dural canal in all disease categories. However, MRI was inferior, irrespective of sagittal and coronal images, to myelography in detecting blocking of the dural canal and intradural findings such as redundant nerve roots. MRI was inferior to selective nerve root infiltration in visualizing the compression of the nerve root, irrespective of diseases; however, there was no difference in abnormal findings of the running of nerve root between the two modalities. Transverse MRI was superior to CT in visualizing the nerve root. Thus, MRI alone is insufficient for the diagnosis of degenerative lumbar spinal diseases, and the other modalities should be supplementary for pathophysiological understanding of these diseases.

    Full Text Available Abstract Background Pelvic incidence, sacral slope and slip percentage have been shown to be important predicting factors for assessing the risk of progression of low- and high-grade spondylolisthesis. Biomechanical factors, which affect the stress distribution and the mechanisms involved in the vertebral slippage, may also influence the risk of progression, but they are still not well known. The objective was to biomechanically evaluate how geometric sacral parameters influence shear and normal stress at the lumbosacral junction in spondylolisthesis. Methods A finite element model of a low-grade L5-S1 spondylolisthesis was constructed, including the morphology of the spine, pelvis and rib cage based on measurements from biplanar radiographs of a patient. Variations provided on this model aimed to study the effects on low grade spondylolisthesis as well as reproduce high grade spondylolisthesis. Normal and shear stresses at the lumbosacral junction were analyzed under various pelvic incidences, sacral slopes and slip percentages. Their influence on progression risk was statistically analyzed using a one-way analysis of variance. Results Stresses were mainly concentrated on the growth plate of S1, on the intervertebral disc of L5-S1, and ahead the sacral dome for low grade spondylolisthesis. For high grade spondylolisthesis, more important compression and shear stresses were seen in the anterior part of the growth plate and disc as compared to the lateral and posterior areas. Stress magnitudes over this area increased with slip percentage, sacral slope and pelvic incidence. Strong correlations were found between pelvic incidence and the resulting compression and shear stresses in the growth plate and intervertebral disc at the L5-S1 junction. Conclusions Progression of the slippage is mostly affected by a movement and an increase of stresses at the lumbosacral junction in accordance with spino-pelvic parameters. The statistical results provide

    L4–L5 traumatic spondylolisthesis has been rarely reported in the literature. At lumbar spine level traumatic dislocation lesion realizes“traumatic spondylolisthesis or traumatic bilateral lumbar facet locked syndrome”. The aim of the present paper is to report this rare lesion and discuss its mechanism and management. A case report is followed by Literature review made on Medline and scholar google database from 2000 to 2015. The case report concerned a 33-year-old man, who refused to wear a seat belt, injured his lumbar spine following a motor vehicle accident. L4-L5 spondylolisthesis occurred after the vehicle rolled over several times. Sixteen months after the accident the patient had a favorable outcome. Literature review on Medline and scholar google database from 2000 to 2015 was carried out and five cases of traumatic spondylolisthesis were found. The Sex ratio was 3/2. Surgical treatment consisted of posterolateral interbody fusion. Traumatic lumbar spine spondylolisthesis is rare. When it occurs, it is always associated with vertebral lumbar fracture. L4-L5 traumatic spondylolisthesis was caused by a high-energy mechanism and improper use of seat belt.

    Objective To analyze the effectiveness of combined treatment of lumbar spondylolisthesis with MED, Quadrant, and Sextant-R systems. Methods Between August 2006 and June 2011, 35 patients with lumbar spondylolisthesis were treated, including 11 cases of isthmic spondylolisthesis and 24 cases of degenerative spondylolisthesis. There were 25 males and 10 females, with a mean age of 55 years (range, 33-71 years). The mean disease duration was 37 months (range, 8-75 months). Spondylolisthesis occurred at L4,5 level in 21 patients and at Ls, S1 level in 14 patients. According to Meyerding classification, 35 cases were rated as dergee I. The minimally invasive surgeries were performed by paraspinal muscle approach; Quadrant system was used for decompression and fusion at severe side, MED system for windowing of lamina at mild side, and Sextant-R system for fixation and reduction. Visual analogue scale (VAS) score was used to evaluate pain, Oswestry disability index (ODI) to evaluate clinical outcomes, spondylolishesis ratio and intervertebral height to evaluate spondylolisthesis reduction. Results Lumbar continuous thin layer CT at postoperation showed that no pedicle screw invaded spinal canal and intervertebral fusion device was at good position. Incisions healed by first intention. All patients were followed up 18-38 months (mean, 26 months). All patients got bone fusion and had no internal fixation failure by radiologic examination at 1 year after operation. Low back pain was relieved, lumbar function improved obviously, and satisfactory reduction of spondylolisthesis was obtained. At 2 weeks and 1 year after operation, the VAS score, ODI score, spondylolisthesis ratio, and intervertebral height were significantly improved when compared with preoperative ones (P 0.05) between at 2 weeks and at 1 year after operation. Conclusion Minimally invasive surgical management for lumbar spondylolisthesis via MED, Quadrant, and Sextant-R systems is a safe and effective surgical

    The rapid growth of spine degenerative surgery has led to unrelenting efforts to define and prevent possible complications, the incidence of which is probably higher than that reported and varies according to the region of the spine involved (cervical and thoracolumbar) and the severity of the surgery. Several issues are becoming progressively clearer, such as complication rates in primary versus revision spinal surgery, complications in the elderly, the contribution of minimally invasive surgery to the reduction of complication rate. In this paper the most common surgical complications in degenerative spinal surgery are outlined and discussed.

    Objective: Evaluating the effectiveness of low-level laser therapy (LLLT) in alleviating the symptoms of lumbar spondylolisthesis. Materials and Methods: Laser was irradiated for 2 mm at six symmetric points along the lumbosacral spine and 5 points along the referred point ofpain, six times a week for 2 weeks (890 nm; 8 J/cm2; pulsed at 1500 Hz). Perception of benefit, level of function was assessed by the Oswestry disability index, lumbar mobility range of motion and low back pain intensity. Results and Discussion: Results showed a complete reduction in pain and improvement in function in the patient. This case report suggests that low-level laser therapy (LLLT) could play a role in conservative management of low-grade lumbar spondylolisthesis.

    This report describes and evaluates a physical therapy intervention in a 15-year-old male handball player with low grade isthmic spondylolisthesis and associated spinopelvic misalignment (shear-stress type). Upon examination, increased lumbar lordosis, horizontal sacrum and anterior pelvic tilting were mainly associated with altered resting length and extensibility of the iliopsoas, hip adductors and erector spinae muscles. The intervention was directed at improving the muscles resting length and extensibility balance within a global postural alignment perspective (global postural reeducation). After the treatment period, lumbar lordosis, sacral slope and anterior pelvic tilting decreased 17.2°, 16.5° and 15.1° respectively. Global postural reeducation was effective in changing spinopelvic alignment related to low grade isthmic spondylolisthesis. This treatment option should be considered as a potential nonsurgical alternative for this condition.

    Full Text Available Eight 28-day-old broiler chickens of both sexes were examined. Clinical signs, gross findings, radiological, and histopathological changes were described. Spondylolisthesis was characterized by dorsal displacement of the sixth and seventh thoracic vertebrae, resulting in compression of the spinal cord. The major clinical manifestation was paraplegia. Risk factors such as genetics, nutrition, stress, rate of growth, and age were discussed.

    Surgical correction for kyphoscoliosis is increasingly being performed for patients with mucopolysaccharidosis (MPS). Reported case series have predominantly included patients with Type I (Hurler) and Type IV (Morquio) MPS. To their knowledge, the authors describe the first case report of surgical management of thoracolumbar kyphoscoliosis in Hunter syndrome (MPS Type II) and the rare occurrence of lumbar spondylolisthesis following surgical stabilization. A 12-year-old boy with Hunter syndrome presented with severe thoracolumbar kyphoscoliosis and no associated symptoms. Spinal radiographs demonstrated kyphosis of 48° (T11-L3) and scoliosis of 22° (T11-L3) with an anteriorly hypoplastic L-1 vertebra. The deformity progressed to kyphosis of 60° and scoliosis of 42° prior to surgical intervention. Spinal CT scans identified left T12-L1 facet subluxation, causing anterior rotatory displacement of the spine proximal to L-1 and bilateral L-5 isthmic spondylolysis with no spondylolisthesis. A combined single-stage anterior and posterior instrumented spinal arthrodesis from T-9 to L-4 was performed. Kyphosis and scoliosis were corrected to 4° and 0°, respectively. Prolonged ventilator support and nasogastric feedings were required for 3 months postoperatively. At 2.5 years following surgery, the patient was asymptomatic, mobilizing independently, and had achieved a solid spinal fusion. However, he had also developed a Grade II spondylolisthesis at L4-5; this was managed nonoperatively in the absence of symptoms or further deterioration of the spondylolisthesis to the 3.5-year postoperative follow-up visit. Satisfactory correction of thoracolumbar kyphoscoliosis in Hunter syndrome can be achieved by combined anterior/posterior instrumented arthrodesis. The risk of developing deformity or instability in motion segments adjacent to an instrumented fusion may be greater in patients with MPS related to the underlying connective tissue disorder.

    Full Text Available Abstract Introduction In contrast to spondylolisthesis of the lumbar spine, non-traumatic cervico-thoracic spondylolisthesis is a very rare lesion. Even minor changes in the displacement of the vertebrae or the cord can lead to cervical myelopathy and paralysis. Since only a few cases have been well-documented, there is currently no clear preference between operative techniques. Case presentation We describe the case of a 63-year-old Caucasian man with a 13 mm spondylolisthesis between C7 and T1. Within a few months, a progressive cervical myelopathy developed as he began to suffer pain and loss of function of his digits and was no longer able to walk unassisted. In an interdisciplinary collaboration between neurological and orthopedic surgeons, a ventral-dorsal-ventral approach was performed on one vertebral section. The ventral removal of the intervertebral disc was followed by laminectomy and dorsal instrumentation. A new application technique was established by inserting bicortical screws into the transverse processes of T2 and T3. The structure was subsequently stabilized by the ventral insertion of a Harms basket. The procedure was successful as it halted progression of the myelopathy. The patient demonstrated improved sensitivity and recovered the ability to walk unassisted. He has now been able to walk unassisted for two years postoperatively. Conclusion This paper describes a successful treatment for a very rare case of cervico-thoracic spondylolisthesis. The technique of inserting bicortical screws into the transverse processes is a fast, safe and successful method that does not require the use of intraoperative radiographs for placement of the bicortical screws into the transverse processes.

    In L5-S1 spondylolisthesis, it has been clearly demonstrated over the past decade that sacro-pelvic morphology is abnormal and that it can be associated to an abnormal sacro-pelvic orientation as well as to a disturbed global sagittal balance of the spine. The purpose of this article is to review the work done within the Spinal Deformity Study Group (SDSG) over the past decade, which has led to a classification incorporating this recent knowledge. The evidence presented has been derived from the analysis of the SDSG database, a multi-center radiological database of patients with L5-S1 spondylolisthesis, collected from 43 spine surgeons in North America and Europe. The classification defines 6 types of spondylolisthesis based on features that can be assessed on sagittal radiographs of the spine and pelvis: (1) grade of slip, (2) pelvic incidence, and (3) spino-pelvic alignment. A reliability study has demonstrated substantial intra- and inter-observer reliability similar to other currently used classifications for spinal deformity. Furthermore, health-related quality of life measures were found to be significantly different between the 6 types, thus supporting the value of a classification based on spino-pelvic alignment. The clinical relevance is that clinicians need to keep in mind when planning treatment that subjects with L5-S1 spondylolisthesis are a heterogeneous group with various adaptations of their posture. In the current controversy on whether high-grade deformities should or should not be reduced, it is suggested that reduction techniques should preferably be used in subjects with evidence of abnormal posture, in order to restore global spino-pelvic balance and improve the biomechanical environment for fusion.

    Full Text Available The purpose was to reveal patterns of morphometric characteristics variability of lumbar vertebrae and sacrum for a choice of more adequate selection of standard sizes and introduction orientation of corrigent metalware at surgical treatment of spondylolisthesis. Preparations of lumbar vertebrae and sacrum of 60 skeletons, 110 Kt-grams of men and women of the first and second periods of mature age without visible pathology of a backbone and 300 Kt-grams of patients with spondylolisthesis. The data on age variability and sexual dimorphism of lumbar vertebrae and sacrum were obtained. The analysis of results of surgical treatment of 288 patients with spondylolisthesis during 1995-2008 was carried out. 160 patients were managed with preoperative planning, taking into account morphometric characteristics of vertebrae and sacrum since 2003. It is necessary to install and arrange metalware at reduction taking into account features of back structures and forward basic complex of lumbar vertebrae and sacrum; that allows to receive adequate decompression of neurovascu-lar structures in 85-90% cases, reliable correction and stabilization of damaged lumbosacral segments

    Full Text Available To evaluate the association of redundant nerve roots of cauda equina (RNRCE with the degree of lumbar spinal stenosis (LSS and with spondylolisthesis. Method After Institutional Board approval, 171 consecutive patients were retrospectively enrolled, 105 LSS patients and 66 patients without stenosis. The dural sac cross-sectional area (CSA was measured on T2w axial MRI at the level of L2-3, L3-4 and L4-5 intervertebral discs. Two blinded radiologists classified cases as exhibiting or not RNRCE in MRI. Intra- and inter-observer reproducibility was assessed. Results RNRCE were associated with LSS. RRNCE was more frequent when maximum stenosis<55 mm2. Substantial intra- observer agreement and moderate inter-observer agreement were obtained in the classification of RNRCE. Spondylolisthesis was identified in 27 patients and represented increased risk for RRNCE. Conclusion LSS is a risk factor for RNRCE, especially for dural sac CSA<55 mm2. LSS and spondylolisthesis are independent risk factors for RNRCE.

    Full Text Available Most unilateral pedicle stress fractures occur on the contralateral side of patients with unilateral spondylolysis. However, there are few reports of unilateral pedicle stress fractures in patients with bilateral spondylolysis and spondylolisthesis. We report a unique case of unilateral pedicle stress fracture in a long-term hemodialysis patient with isthmic spondylolisthesis. A 65-year-old man who had undergone hemodialysis presented with lower back pain that had persisted for several years. The patient experienced severe right lower extremity pain with no history of trauma. Computed tomography revealed unilateral pedicle fracture with bilateral L5 spondylolysis and spondylolisthesis with progression of scoliosis. The patient underwent Gill laminectomy of L5 with pedicle screw fixation at L4-S1 and interbody fusion at L5-S1. The patient’s leg pain ceased immediately, and he began walking without leg pain. In our present patient, development of scoliosis caused by destructive spondyloarthropathy may have contributed to a unilateral pedicle fracture.

    Highlights: • MR imaging with straightened lower extremities was tested in spondylolisthesis. • This technique is more accurate than conventional MR imaging in detecting slip. • Level of spondylolisthesis is the only independent predictor of severity of slip. - Abstract: Objectives: To compare the degree of slip in spondylolisthesis on supine magnetic resonance (MR) images obtained with flexed and straightened lower extremities. Methods: Supine spinal MR studies were performed in 100 cases of symptomatic spondylolisthesis with flexed and then straightened lower extremities. The angle of lumbar lordosis (by Cobb's method) and the degree of slip (by Taillard's method) were compared between the two sets of images. Results: The mean angle of lumbar lordosis increased from 51.65 ± 8.57° on MR images with flexed lower limbs to 57.39 ± 9.05° on MR images with straightened lower limbs (p < 0.001; mean percent increase: 11.51%). Similar change was also observed for the mean degree of slip (from 25.80 ± 7.74% to 28.68 ± 7.93%, p < 0.001; mean percent increase: 12.60%). After MR imaging with straightened lower extremities 22 out of 54 initially grade I cases had grade II disease (p < 0.001). Conclusions: Supine magnetic resonance imaging with straightened lower extremities detects higher degree of slippage in symptomatic patients with spondylolisthesis compared to conventional MRI with flexed lower extremities.

    Somatosensory profiling in affected and non-affected body regions can strengthen our insight regarding the underlying pain mechanisms, which can be valuable in treatment decision making and to improve outcomes, in patients with degenerative lumbar spine disorders pre-surgery. The aim was to describe somatosensory profiles in patients with degenerative lumbar spine disorders, to identify the proportion with altered somatosensory profile, and to analyze demographic characteristics, self-reported function, pain, and health pre- and 3 months post-surgery. In this prospective cohort study in a Spine Clinic, 105 patients scheduled for surgery for spinal stenosis, disc herniation, degenerative disc disease, or spondylolisthesis were consecutively recruited. Exclusion criteria were; indication for acute surgery or previous surgery at the same spinal level or severe grade of pathology. Quantitative sensory testing (QST) and self-reported function, pain, and health was measured pre- and 3 months post-surgery. The somatosensory profile included cold detection threshold, warmth detection threshold, cold pain threshold, heat pain threshold and pressure pain threshold in affected and non-affected body regions. On a group level, the patients' somatosensory profiles were within the 95% confidence interval (CI) from normative reference data means. On an individual level, an altered somatosensory profile was defined as having two or more body regions (including a non-affected region) with QST values outside of normal ranges for reference data. The 23 patients (22%) with altered somatosensory profiles, with mostly loss of function, were older (P = 0.031), more often female (P = 0.005), had higher back and leg pain (P = 0.016, 0.020), lower mental health component summary score (SF-36 MCS) (P = 0.004) and larger pain distribution (P = 0.047), compared to others in the cohort. Post-surgery there was a tendency to worse pain, function and health in the group with

Lack of precise observations and documentation of aspects within the complex entity of DDD might partially be the cause of poor correlation of radiographic findings to clinical symptoms. This literature review summarizes the current knowledge on MRI in DDD and outlines the diagnostic limitations. The review further sensitizes the reader toward awareness of potentially untended aspects of DDD and the interaction of DDD and endplate changes. A summary of the available classifications for DDD is provided.

  12. Physiochemical basis of human degenerative disease

    2015-03-01

    Full Text Available The onset of human degenerative diseases in humans, including type 2 diabetes, cardiovascular disease, neurological disorders, neurodevelopmental disease and neurodegenerative disease has been shown to be related to exposures to persistent organic pollutants, including polychlorinated biphenyls, chlorinated pesticides, polybrominated diphenyl ethers and others, as well as to polynuclear aromatic hydrocarbons, phthalates, bisphenol-A and other aromatic lipophilic species. The onset of these diseases has also been related to exposures to transition metal ions. A physiochemical mechanism for the onset of degenerative environmental disease dependent upon exposure to a combination of lipophilic aromatic hydrocarbons and transition metal ions is proposed here. The findings reported here also, for the first time, explain why aromatic hydrocarbons exhibit greater toxicity than aliphatic hydrocarbons of equal carbon numbers.

  13. [Pharmacotherapy of degenerative joint diseases in dogs].

    Klee, S; Ungemach, F R

    1998-02-01

    The pharmacological treatment of degenerative joint diseases is restricted essentially to the alleviation of acute symptoms of activated arthropathies. Suitable compounds are the non-steroidal and steroidal antiinflammatory drugs, which however do not allow long-term therapy due to their overall catabolic effects on cartilage metabolism. Since causally acting drugs are not available, the progressive course of the disease cannot be prevented so far. Natural components of the cartilage's matrix, being recommended as so-called chondroprotective drugs, do not fulfill the expectation of a remission of the degenerative process. Indeed, regarding the necessity of multiple local applications of these drugs, they are not superior to antiinflammatory drugs. Provided careful dosing and surveillance of untoward gastrointestinal effects, non-steroidal antiinflammatory agents still are the drugs of first choice.

    The surgical management of high-grade spondylolisthesis in adolescents remains a controversial issue. Because the basic procedure, posterolateral fusion, is associated with a significant rate of pseudarthrosis and listhesis progression, there is a pressing need for alternative surgical techniques. In the present report, the authors describe the case of an adolescent patient with significant low-back pain who was found to have Grade IV spondylolisthesis at L5-S1 that was treated with transsacral transdiscal screw fixation. Bilateral pedicle screws were placed starting from the top of the S-1 pedicle, across the L5-S1 intervertebral disc space, and into the L-5 body. At 14 months after surgery, the patient had considerable improvement in his pain and radiographic fusion across L5-S1. The authors conclude that transsacral transdiscal pedicle screws may serve as an efficacious and safe option for the correction of high-grade spondylolisthesis in adolescent patients.

    2014-07-01

    Interbody fusion techniques have been promoted as an adjunct to lumbar fusion procedures in an effort to enhance fusion rates and potentially improve clinical outcome. The medical evidence continues to suggest that interbody techniques are associated with higher fusion rates compared with posterolateral lumbar fusion (PLF) in patients with degenerative spondylolisthesis who demonstrate preoperative instability. There is no conclusive evidence demonstrating improved clinical or radiographic outcomes based on the different interbody fusion techniques. The addition of a PLF when posterior or anterior interbody lumbar fusion is performed remains an option, although due to increased cost and complications, it is not recommended. No substantial clinical benefit has been demonstrated when a PLF is included with an interbody fusion. For lumbar degenerative disc disease without instability, there is moderate evidence that the standalone anterior lumbar interbody fusion (ALIF) has better clinical outcomes than the ALIF plus instrumented, open PLF. With regard to type of interbody spacer used, frozen allograft is associated with lower pseudarthrosis rates compared with freeze-dried allograft; however, this was not associated with a difference in clinical outcome.

    1988-12-01

    New noninvasive techniques as well as conventional methods were used to evaluate skeletal mass in the following three populations of adult white women as follows: (1) 79 subjects with preexisting idiopathic scoliosis designated as unstable (US) because of the associated presence in the lumbar spine of lateral spondylolisthesis with segmental instability; (2) 67 subjects with preexisting idiopathic scoliosis without lateral spondylolisthesis designated as stable (SS); and (3) 248 age-matched nonscoliotic controls. Ages in all three groups were categorized into premenopausal (25-44 years), perimenopausal (45-54 years), and postmenopausal (55-84 years). The results showed higher scoliosis morbidity in the US compared to the SS populations. The prevalence and severity of osteoporosis were markedly increased in US versus SS populations. Femoral neck density determined by dual-photon absorptiometry techniques averaged 26% to 48% lower in all age categories of US patients compared to controls. These changes were found in the youngest age groups, indicating reductions in bone mineral content earlier in the adult life of white women with a specific type of high-morbidity US characterized by the marker of lateral spondylolisthesis.

    2015-11-01

    Full Text Available Spondylolisthesis is derived from the Greek words–spondyl (Vertebra and olisthesis (To slip. The prevalence of spondylolisthesis in general population is approximately 5% and is about equal in men and women. Spondylolysis is a descriptive term referring to a defect in the pars interarticularis. Few studies have investigated the long term effect of posterior lumbar interbody fusion on functional outcome. OBJECTIVES: Objectives of the study are to evaluate the safety, efficacy and functional outcome of surgical management of spondylolisthesis with Moss-Miami instrumentation and posterior spinal fusion. METHODOLOGY: From November 2012 to April 2014, a total of 20 patients, operated with Moss-Miami instrumentation and posterior spinal fusion were followed up and evaluated based on ODI score. RESULTS: There were 20 patients with spondylolisthesis at L4-L5 and L5-S1, who were managed with Moss-Miami instrumentation and posterior spinal fusion; 70% of patients had spondylolisthesis at L5–S1. Most of the patients were in 3rd and 4th decade of life with a female predominance of 18 cases (90%. In this study 55% of patients had Grade I listhesis and 45% had Grade II listhesis. Bony fusion was achieved for all the patients. In this study 12(60% patients had excellent, 5(25% had good, 2(10% fair and 1(5% had poor results based on ODI scoring. CONCLUSION: Surgical fixation of spondylolisthesis using Moss–Miami instrumentation and posterior lumbar interbody graft is still a safe, promising and appealing technique especially in low-grade listhesis.

    This prospective interventional study carried out at Bangabandhu Sheikh Mujib Medical University and a private hospital in Dhaka, Bangladesh during the period from October 2003 to September 2011. Surgical treatment of degenerative disc disease (DDD) should aim to re-expand the interbody space and stabilize until fusion is complete. The present study conducted to find out the efficacy of using interbody fusion device (Cage) to achieve interbody space re-expansion and fusion in surgical management of DDD. We have performed the interventional study on 53 patients, 42 female and 11 male, with age between 40 to 67 years. All the patients were followed up for 36 to 60 months (average 48 months). Forty seven patients were with spondylolisthesis and 06 with desiccated disc. All subjects were evaluated with regard to immediate and long term complications, radiological fusion and interbody space re-expansion and maintenance. The clinical outcome (pain and disability) was scored by standard pre and postoperative questionnaires. Intrusion, extrusion and migration of the interbody fusion cage were also assessed. Forty seven patients were considered to have satisfactory outcome in at least 36 months follow up. Pseudoarthrosis developed in 04 cases and 06 patients developed complications. In this series posterior lumbar interbody fusion (PLIF) with interbody cage and instrumentation in DDD showed significant fusion rate and maintenance of interbody space. Satisfactory outcome observed in 88.68% cases.

  20. 'Lumbar Degenerative Kyphosis' Is Not Byword for Degenerative Sagittal Imbalance: Time to Replace a Misconception.

    Lumbar degenerative kyphosis (LDK) is a subgroup of the flat-back syndrome and is most commonly caused by unique life styles, such as a prolonged crouched posture during agricultural work and performing activities of daily living on the floor. Unfortunately, LDK has been used as a byword for degenerative sagittal imbalance, and this sometimes causes confusion. The aim of this review was to evaluate the exact territory of LDK, and to introduce another appropriate term for degenerative sagittal deformity. Unlike what its name suggests, LDK does not only include sagittal balance disorder of the lumbar spine and kyphosis, but also sagittal balance disorder of the whole spine and little lordosis of the lumbar spine. Moreover, this disease is closely related to the occupation of female farmers and an outdated Asian life style. These reasons necessitate a change in the nomenclature of this disorder to prevent misunderstanding. We suggest the name "primary degenerative sagittal imbalance" (PDSI), which encompasses degenerative sagittal misalignments of unknown origin in the whole spine in older-age patients, and is associated with back muscle wasting. LDK may be regarded as a subgroup of PDSI related to an occupation in agriculture. Conservative treatments such as exercise and physiotherapy are recommended as first-line treatments for patients with PDSI, and surgical treatment is considered only if conservative treatments failed. The measurement of spinopelvic parameters for sagittal balance is important prior to deformity corrective surgery. LDK can be considered a subtype of PDSI that is more likely to occur in female farmers, and hence the use of LDK as a global term for all degenerative sagittal imbalance disorders is better avoided. To avoid confusion, we recommend PDSI as a newer, more accurate diagnostic term instead of LDK.

    Abstract Background: A prospective, randomized, double-blind, placebo-controlled study was performed. The routine usage of TA in spinal surgery is controversial. Only a few studies have focused on patients undergoing posterior lumbar surgery for stenosis or spondylolisthesis, although a large clinical cohort exists in the population. This study aimed to evaluate the effect and safety of TA in reducing perioperative blood loss in posterior lumbar surgery for stenosis or spondylolisthesis. Methods: 100 eligible patients out of 126 were randomized to receive either a bolus dose of 30 mg/kg TA i.v, a maintenance dosage of 2 mg/kg/h TA, or an equivalent volume of normal saline. The pedicle screw system was used for fixing in all the patients, followed by decompression and posterior lumbar interbody fusion. The primary outcomes were intraoperative estimated blood loss and total blood loss. The secondary outcomes were receiving packed red blood cells and postoperative hemoglobin and hematocrit levels. Results: In total, 4 patients were excluded from the analyses, 50 patients were in the TA group, and 46 in the placebo group. The demographic and baseline data between the groups were not statistically different. The intraoperative estimated blood loss and the total blood loss were 33% and 41% lower in the TA group than the placebo group, respectively. The blood transfusion rate did not vary significantly (P = 0.191). Except a patient with a dural tear in the placebo group, no other complications were observed. Conclusion: TA significantly reduced the perioperative blood loss in patients undergoing posterior lumbar surgery for stenosis or spondylolisthesis. PMID:28072709

    Full Text Available Background and purpose: The relationship between presence of lumbo sacral transitional vertebra (LSTV and disc degenerative changes is unclear. The aim of the study was to examine the relation between different types of LSTV and disc degenerative changes at the transitional and the adjacent cephalad segment. Material and methods: Sixty-three patients (mean age 51.48 ± 13.51 out of 200 adults with low back pain who performed MRI examination of the lumbo sacral spine, classified as positive for LSTV, were included in the study. Annular tears, disc degeneration according to Phirmann classification and disc herniations were evaluated and graded at transitional and adjacent cephalad level. Results: The severity of disc degeneration at the transitional level and the adjacent level correlated with the types of LSTV. Severe disc degenerative changes were most frequent in articulated connection LSTV types and incombined LSTV type at the transitional level and in osseus connection LSTV types at the adjacent cephalad level. These changes were more frequent in unilateral articulated connection LSTV subtype (64% vs 54%; and in unilateral osseus connection LSTV subtype (25% vs no patients at transitional level, and in bilateral osseus connection LSTV subtype (100% vs 50% at the level above. High prevalence of disc herniations was observed in articulated connection LSTV types as well as in unilateral osseus connection LSTV subtype at transitional and the adjacent cephalad level. At the transitional level higher prevalence of disc herniations was characteristic for unilateral articulated connection LSTV sub type (46%vs 41% and for unilateral osseus connection LSTV subtype (50% vs no patients. At the adjacent level higher prevalence of disc herniations was observed in bilateral articulated connection LSTV subtype (38% vs 27% and in bilateral osseus connection LSTV subtype (50% vs 25%. Conclusions: The compact osseus connection (osseus bridging vs articular

    Degenerative spinal disorders, including intervertebral disc disease and spondylosis, seldom occur in domestic cats. In contrast, a retrospective study of 13 lions (Panthera leo), 16 tigers (Panthera tigris), 4 leopards (Panthera pardis), 1 snow leopard (Panthera uncia), and 3 jaguars (Panthera onca) from the Knoxville Zoo that died or were euthanatized from 1976 to 1996 indicated that degenerative spinal disease is an important problem in large nondomestic felids. The medical record, radiographic data, and the necropsy report of each animal were examined for evidence of intervertebral disc disease or spondylosis. Eight (three lions, four tigers, and one leopard) animals were diagnosed with degenerative spinal disease. Clinical signs included progressively decreased activity, moderate to severe rear limb muscle atrophy, chronic intermittent rear limb paresis, and ataxia. The age at onset of clinical signs was 10-19 yr (median = 18 yr). Radiographic evaluation of the spinal column was useful in assessing the severity of spinal lesions, and results were correlated with necropsy findings. Lesions were frequently multifocal, included intervertebral disc mineralization or herniation with collapsed intervertebral disc spaces, and were most common in the lumbar area but also involved cervical and thoracic vertebrae. Marked spondylosis was present in the cats with intervertebral disc disease, presumably subsequent to vertebral instability. Six of the animals' spinal cords were examined histologically, and five had acute or chronic damage to the spinal cord secondary to disc protrusion. Spinal disease should be suspected in geriatric large felids with decreased appetite or activity. Radiographic evaluation of the spinal column is the most useful method to assess the type and severity of spinal lesions.

    Retinal degenerative diseases are major causes of vision loss and blindness worldwide and are characterized by chronic and progressive neuronal loss. One common feature of retinal degenerative diseases and brain neurodegenerative diseases is chronic neuroinflammation. There is growing evidence that retinal microglia, as in the brain, become activated in the course of retinal degenerative diseases, having a pivotal role in the initiation and propagation of the neurodegenerative process.

    The aim of this prospective study was to assess the sagittal alignment of the spine and pelvis before and after surgical treatment of isthmic spondylolisthesis with flat sacrum. At the same time, the functional outcome was analyzed and correlation examined. This study comprises analysis of 30 subjects (mean age 43 years) with isthmic spondylolisthesis and an average follow-up of 2.5 years after posterior spinal fusion. Radiological spinopelvic parameters were measured and functional evaluation was made using the Oswestry Disability Index. Significant improvement toward more normal values for PT and SS in relation to PI was observed after surgery. Pelvic incidence was unaffected by surgery. Correction of the spinosacral angle shows that the anterior tilt with anterior sagittal imbalance due to spondylolisthesis may be corrected by reduction and fusion of the slipped level. Functional outcome was satisfactory with a statistically significant difference between preoperative values and final follow-up values. The sub-group of patients with insufficient restoration of sagittal balance parameters had less good outcomes than the others. Surgical management of low- and mid-grade isthmic spondylolisthesis showed good clinical outcome with restoration of correct values for the pelvic position-dependent parameters, i.e., pelvis tilt, sacral slope, C7 plumb line position and SSA.

    Full Text Available Background Context. Patient with a C2 fracture and entrapment of the right vertebral artery in the fracture gap. Purpose. Presentation of a case with follow-up until end of treatment. Study Design. Case report. Methods. A 25-year-old woman was brought into our emergency room after falling while riding a horse. She complained of pain in the cervical spine. Clinical examinations showed local tenderness at the upper cervical spine and painful impairment of the mobility of the neck, with no signs of neurological impairment. Radiological diagnostics revealed a traumatic C2/3 spondylolisthesis. A computer tomography (CT angiographic scan showed a dislocation of the right vertebral artery into the fracture gap without injury to the artery. Open reduction and osteosynthesis were considered of too high risk. Therefore, we conducted fracture treatment with closed reduction and halo fixation. After removal of the halo fixator, the patient was given a soft cervical collar and was advised to rest for additional 6 weeks before beginning gradual activity. Results. Conventional follow-up revealed osseous consolidation and a CT angiographic scan showed consistent blood flow to the artery. Conclusion. Halo fixation was a safe and effective therapy strategy in the case of vertebral artery entrapment after traumatic C2 spondylolisthesis.

    Full Text Available Degenerative valvular disease or endocardiosis is the most common cardiovascular pathology in dogs. It is characterized by regurgitation of blood into the atria with decreased cardiac output, leading to volume overload with eccentric hypertrophy and congestive heart failure. This report describes the clinical and autopsy findings of a dog, suggestive of valvular endocardiosis. The patient was admitted to the outpatient Veterinary Clinic “Carlos Martínez Hoyos” at the University of Nariño (Pasto, Colombia. His owner said the dog was sick for two months, with signs of respiratory disease, weight loss, and decay. Clinical examination showed very pale mucous membranes, inspiratory dyspnea, rale, split S2, grade 4 mid-systolic murmur of regurgitation, and abdominal dilatation with sign of positive shock wave. Necropsy evidenced plenty of translucent watery material in the abdominal, chest and pericardium cavity, severely enlarged and rounded heart with thickened atrioventricular valves, moderate reduction in liver size and signs of lobulation, severely diminished and pale kidneys with irregular surface showing the presence of multiple cystic areas in corticomedullary region. Samples were taken from these tissues and fixed in 10% buffered formalin to be processed for histopathological analysis at the Laboratory of Pathology at the University of Nariño, using hematoxylin and eosin stain. This way, degenerative valvular disease was diagnosed.

    Full Text Available Background: Since centuries ago it has been written about lumbar pain, still its treatment remains enigmatic. At present, all developed spinal surgery institutions use the transpedicular fixation methods, but we lack the right technology for what we use the posterolateral fusion. Objetive: to evaluate the results in the aplicate of the posterolateral fusion in spondylolisthesis of the lumbosacral segment. Methods: A Retrospective-descriptive, correlational, and of a series of cases study, carried out in traumatology and orthopaedics service of the Universitarian Provincial Hospital ¨Dr. Gustavo Aldereguía Lima¨ of Cienfuegos, in which were included the 33 patients with spondylisthesis of the lumbosacral segment, who received inter-transversal posterolateral fusion. All the patients got plain anteroposterior and lateral radiography, including right and left slanting sights, to the doubtful cases dynamic sights with flexion and extension of the trunk were applied. To the patients with signs of radicular irritation, a digitalized axial tomography was applied. Results: The main etiological causes in these patients were the isthmic one, followed by degenerative and dysplastic ones. The posterolateral function was carried out alone or combined with other surgical techniques; to the patients with lumbar pain that also had associated signs of radicular irritation were applied exeresis of posterior arch with release of the endangered roots. The more frequent complication was the recurrent pain, present in 6 patients, followed by granuloma of the surgical wound. Conclusions: In spite of lacking a modern instrumentation system, the problem of spondylolisthesis can be solved with only dominating this traditional technique consistent in posterolateral fixation.

    2011-09-01

    Full Text Available Abstract Introduction Traditional surgical management of lumbosacral spondylolisthesis is technically challenging and is associated with significant complications. The advent of minimally invasive surgical techniques offers patients treatment alternatives with lower operative morbidity risk. The combination of percutaneous pedicle screw reduction and an axial presacral approach for lumbosacral discectomy and fusion offers an alternative procedure for the surgical management of low-grade lumbosacral spondylolisthesis. Case presentation Three patients who had L5-S1 grade 2 spondylolisthesis and who presented with axial pain and lumbar radiculopathy were treated with a minimally invasive surgical technique. The patients-a 51-year-old woman and two men (ages 46 and 50-were Caucasian. Under fluoroscopic guidance, spondylolisthesis was reduced with a percutaneous pedicle screw system, resulting in interspace distraction. Then, an axial presacral approach with the AxiaLIF System (TranS1, Inc., Wilmington, NC, USA was used to perform the discectomy and anterior fixation. Once the axial rod was engaged in the L5 vertebral body, further distraction of the spinal interspace was made possible by partially loosening the pedicle screw caps, advancing the AxiaLIF rod to its final position in the vertebrae, and retightening the screw caps. The operative time ranged from 173 to 323 minutes, and blood loss was minimal (50 mL. Indirect foraminal decompression and adequate fixation were achieved in all cases. All patients were ambulatory after surgery and reported relief from pain and resolution of radicular symptoms. No perioperative complications were reported, and patients were discharged in two to three days. Fusion was demonstrated radiographically in all patients at one-year follow-up. Conclusions Percutaneous pedicle screw reduction combined with axial presacral lumbar interbody fusion offers a promising and minimally invasive alternative for the management

    Degenerative cervical myelopathy (DCM) encompasses a spectrum of age-related conditions that result in progressive spinal cord injury through static and dynamic injury mechanisms. Through detailed review of MRIs from prospective AOSpine multicenter studies, the global prevalence of degenerative cervical pathologies of surgically treated DCM patients is reported. MRIs of 458 patients were obtained from North America (n = 197), Europe (n = 92), Latin America (n = 57), and Asia-Pacific (n = 112) and assessed for the type of pathology, source of stenosis, level of maximum cord compression, levels of spinal cord compression (SCC), presence of signal changes on T2-weighted images (T2WI) and T1-weighted images, and the levels of T2WI signal change. The proportion of degenerative changes present alongside other diagnoses was computed as well as the prevalence of pathologies per geographical region. The prevalence of degenerative changes was separated by sex and assessed using χ analysis. Spondylosis was the most frequent cause of SCC (89.7%) and it was frequently accompanied by enlargement of the ligamentum flavum (59.85%). Ossification of the posterior longitudinal ligament (OPLL) was accompanied by spondylosis in 91.7%. Single-level disc pathology, OPLL, and spondylolisthesis had a prevalence of ∼10%. Klippel-Feil syndrome was observed in 2.8%. Single-level pathology was less common in North America, and OPLL was more common and spondylolisthesis less common in Asia-Pacific. Females presented more commonly with single-level disc pathology (P = .013), and males with spondylosis (P = .017) and enlargement of ligamentum flavum (P = .012). Globally, C5-6 was the most frequent maximum compressed site (39.7%) and region for T2WI hyperintensity (38.9%). T2WI hyperintensity more commonly presented in males (P < .001). DCM pathologies, including OPLL, are highly interrelated and rarely present in isolation. Females presented with milder evidence of DCM on MRI. There are also

    An ambispective analysis. The aim of this study was to report the global prevalence of specific degenerative cervical pathologies in patients with degenerative cervical myelopathy (DCM) through detailed review of magnetic resonance imaging (MRIs). DCM encompasses a spectrum of age-related conditions that result in progressive spinal cord injury. MRIs of 458 patients (age 56.4 ± 11.8, 285 male, 173 female) were reviewed for specific degenerative features, directionality of cord compression, levels of spinal cord compression, and signal changes on sagittal T2-weighted imaging (T2WI) and sagittal T1-weighted imaging (T1WI). Data were analyzed for differences between sex using Chi-square tests and geographic variations using Kruskal-Wallis tests. Spondylosis was frequently present (89.7%) and was commonly accompanied by enlargement of the ligamentum flavum (LF) (59.9%). Single-level disc pathology, ossification of posterior longitudinal ligament (OPLL), and spondylolisthesis had a prevalence of ∼10% each. OPLL was accompanied by spondylosis in 91.7%. Klippel-Feil syndrome was observed in 2.0%. The Asia-Pacific region had more OPLL (29%, P = 3 × 10) and less spondylolisthesis (1.9%, P = 0.002). Females presented more commonly with single-level disc pathology (13.9% vs. 6.7%; P = 0.013), and males with spondylosis (92.3% vs. 85.6%; P = 0.02) and enlargement of LF (61.4% vs. 49.1%; P = 0.01). C5 to C6 was the most frequent maximum compressed site (39.5%) and region for T2WI hyperintensity (38.9%). T2WI hyperintensity more commonly presented in males (82.4% vs. 66.7%; P < 0.001). This is the largest report on the prevalence and spectrum of pathology in patients with DCM. Herein, it has been demonstrated that degenerative features are highly interrelated, that females presented with milder MRI evidence of DCM, and that variations exist in the prevalence of pathologies between geographical regions. 2.

    In the last 25 years, scientific research has brought about drastic changes in the concept of low back pain and its management. Most imaging findings, including degenerative changes, reflect anatomic peculiarities or the normal aging process and turn out to be clinically irrelevant; imaging tests have proven useful only when systemic disease is suspected or when surgery is indicated for persistent spinal cord or nerve root compression. The radiologic report should indicate the key points of nerve compression, bypassing inconsequential findings. Many treatments have proven inefficacious, and some have proven counterproductive, but they continue to be prescribed because patients want them and there are financial incentives for doing them. Following the guidelines that have proven effective for clinical management improves clinical outcomes, reduces iatrogenic complications, and decreases unjustified and wasteful healthcare expenditures.

    Full Text Available 【Abstract】Objective: To investigate the material properties of normal and degenerated intervertebral discs (IVDs and examine the effect of degenerative changes on IVD pathology. Methods: A computer-based online search was under-taken to identify English articles about material properties of IVDs published from January 1950 to 2011 in PubMed database. The retrieved keywords included material properties, intervertebral disc and degeneration. Based on the principles of reliability, advancement and efficiency, the obtained data were primarily examined, and the original source was retrieved to read the full-text. Repetitive articles were excluded. The data of material properties of normal and degenerated IVDs were summarized and analyzed by meta-analysis. Results: The data of Young's modulus, Poisson's ratio, shear modulus, hydraulic permeability and intradiscal pres-sure of normal and degenerated IVDs were obtained. Com-pared with normal IVDs, the Young's modulus and shear modulus of annulus fibrosus and nucleus pulposus were higher in degenerated IVDs, the Poisson's ratio was lower while the hydraulic permeability and intradiscal pressure were higher. Besides, the degeneration-related alterations in IVDs had an influence both on itself and other spinal structures, leading to diseases such as bulging disc, discogenic pain and spinal stenosis. Meanwhile, the heavy mechanical loading and injury indicated important pathways to IVD degeneration. Conclusions: To a certain extent, the degenerative changes of IVD influence its material properties. And the degeneration-related alterations of composition can cause structural failure of IVDs, leading to injuries and diseases.

    Retrospective study of a consecutive patient series. To review the radiographic classification of patients with sagittal imbalance due to lumbar degenerative kyphosis (LDK) and to determine correlation between thoracic and lumbar curve. Lumbar degenerative kyphosis is one of the common spinal deformities in Asian countries, especially Korea and Japan. However, there have been few studies regarding the classification and treatment of this disease. Seventy-eight patients with LDK were analyzed and classified according to the standing lateral whole spine findings. Total lumbar lordosis (L1-S1), thoracic kyphosis (T5-T12), sacral slope, thoracolumbar angle (T11-L1), and sagittal vertical axis (SVA) were measured on the lateral view of the whole spine. Spinal curve deformities were classified into 2 groups according to the thoracolumbar (T-L) junction angle: flat or lordotic angle (Group 1; N = 53) and kyphotic angle (Group 2; N = 25). In Group 1, significant correlations between the thoracic and lumbar curves (r = 0.772, P sagittal thoracic compensated group. In contrast, In Group 2, no correlation was found between the thoracic and lumbar curves in the decompensated group (r = 0.179, P = 0.391), but we found a significant correlation between lordosis and sacral slope (r = 0.442, P = 0.027). By this result, Group 2 was classified as sagittal thoracic decompensated group. There was significant difference in SVA between 2 groups (P = 0.020). The angle of the thoracolumbar junction is an important parameter in determining whether a sagittal thoracic compensatory mechanism exists in LDK. We assumed that existence of a compensatory mechanism in the proximal spine is central to the determination of the fusion levels in the treatment of LDK.

    Introducción: la prescripción potencialmente inapropiada incluye el uso de medicamentos que representan mayor riesgo que benefi cio para el paciente. El objetivo fue evaluar la utilidad del instrumento STOPP-START para su detección. Métodos: se realizó un estudio transversal descriptivo, con selección aleatoria de expedientes de adultos mayores con al menos una enfermedad crónica degenerativa, cuya última consulta tuviera máximo dos meses y que hubiesen cumplido con su cita mensual cuando menos cuatro veces en el últimos semestre. Resultados: de los 285 expedientes revisados, 60 % de los pacientes fueron mujeres; la edad promedio fue de 74 ± 6 años. Se revisaron 1749 prescripciones de 126 medicamentos diferentes. La prescripción inapropiada tuvo una prevalencia de 55 % (IC 95 % = 49-61) y la polifarmacia de 87 % (IC 95 % = 83-91). En los padecimientos cardiovasculares, endocrinos y musculoesqueléticos se registró el mayor número de prescripciones y de prescripción potencialmente inapropiada. Se detectó la omisión de uno o más medicamentos indicados en 72 % de 75 circunstancias clínicas específi cas. Conclusiones: el STOPP-START es útil para detectar prescripción potencialmente inapropiada. Es frecuente la omisión de tratamientos preventivos indicados para el adulto mayor con enfermedades crónicas degenerativas.

    Study Design Cross-sectional study of healthy volunteers. Purpose We aimed to investigate the variation in the lumbar facet joint orientation in an adult Asian population. The relationship between the facet joint orientation and muscle cross-sectional area (CSA) of multifidus and erector spinae was also clarified. Overview of Literature Several studies have reported that lumbar pathologies, such as lumbar spondylolysis and degenerative spondylolisthesis, were related to the horizontally shaped lumbar facet joint orientation at the lower lumbar level. However, data regarding variations in the facet joint orientation in asymptomatic subjects have not been well documented. Methods In 31 healthy male adult Asian volunteers, the facet joint orientation and CSA of multifidus and erector spinae were measured using magnetic resonance imaging at the L4–5 and L5–S1 levels. Variation in the facet joint orientation was examined using coefficients of variation (CV). Pearson's product-moment coefficient was used to investigate the relationship between the facet joint orientation and CSA of multifidus and erector spinae. Results Lumbar facet joint orientation had a wider range of variation at L5–S1 (CV=0.30) than at L4–5 (CV=0.18). The L4–5 facet joint orientation had a weak but significant correlation with the CSA of erector spinae (r=0.40; p=0.031). The CSA of the multifidus had no relationship with the facet joint orientation at the L4–5 (r=0.19; p=0.314) and the L5–S1 level (r=0.19; p=0.312). Conclusions The lumbar facet joint orientation was found to have a wide variation, particularly at the L5–S1 in the Asian adult population, and the facet joint orientation had a relationship with the CSA of the erector spinae at the L4–5.

    Variations when measuring slip and lumbar index were studied in three lumbar specimens with different degrees of artificially created L5-S1 spondylolysthesis. Lateral radiographs were obtained with the specimens tilted and/or rotated mimicking an every-day examination situation. Slip and lumbar index were measured; slip was estimated according to a measuring method advocated by Boxall et coll. but slightly modified by us. Six radiologistis evaluated each film independently. The magnitude of interobserver and intraobserver errors and variations due to positioning was found to be equally large-about 15 per cent each. Although the total measurement variation was not equal to the sum of errors involved, radiologic evaluation of degree of spondylolisthesis was found to be highly unreliable.

    We describe the case of a 67-year-old woman with L5-S1 ontogenetic spondylolisthesis treated with pedicle fixation associated with interbody arthrodesis performed with S1-L5 trans-sacral screwing according to the technique of Bartolozzi. The procedure was followed by a wide decompressive laminectomy. The patient had a progressive improvement of the symptoms which gradually disappeared in 12 mo. The radiograph at 6 and 12 mo showed complete fusion system. The choice of treatment in L5-S1 ontogenetic spondylolithesis is related to a correct clinical and diagnostic planning (X-ray, computer tomography magnetic resonance imaging, Measurement). In particular, the severity index and the square of unstable zone, and the standard measurements already described in the literature, are important to understand and to plane the correct surgical strategy, that require, in most of the times, fusion and interbody artrodesis.

    The athletic activity of the adult U.S. population has increased markedly in the last 20 years. To evaluate the possible long-term effects of such activity on the cervical and lumbar spine, we studied a group of asymptomatic currently very active lifelong male athletes over age 40 (41-69 years old, av. age 53). Nineteen active, lifelong male athletes were studied with MRI and the results compared with previous imaging studies of other populations. An athletic history and a spine history were also taken. Evidence of asymptomatic degenerative spine disease was similar to that seen in published series of other populations. Degenerative changes including disk protrusion and herniation, spondylosis, and spinal stenosis were present and increased in incidence with increasing patient age. In this group, all MRI findings proved to be asymptomatic and did not limit athletic activity. The incidence of lumbar degenerative changes in our study population of older male athletes was similar to those seen in other populations. 14 refs., 8 figs., 1 tab.

    Full Text Available Objective: To assess the most frequent chronic diseases in the elderly population of a private clinic of Physiotherapy. Methods: We assessed medical records of clients who received treatment at a Physiotherapy clinic in the period 2005 to 2008, looking for chronic diseases as diagnosis and/or related to them. Of these, we selected those which contained birth date and/or aged sixty-five years or above. An instrument like a check list, developed by the researchers, identified: quantity, gender, medical diagnosis and comorbidities. For quantification of variables we applied simple percentage calculation. Results: In the study period, there were four hundred fifty-eight records, of which forty-nine corresponded to the survey’s inclusion criteria. The majority 59.2% (n=29 referred to the year 2008; 26.6% (n=13 being males and 73.4% (n=36 females. The most commonly found diagnosis comprised osteoarthritis 57.1% (n=28, fracture and/or history of fractures 24.4% (n=12 and other diagnosis 48.9% (n=24. Associated chronic diseases included diabetes mellitus 18.3% (n=9 and systemic hypertension 57.1% (n=23. Conclusion: Chronic degenerative diseases in elderly have received increasing attention from health professionals; osteoarthritis being the most common diagnosis in this study, followed by fracture and/or history of fractures. The comorbidities represented a greater negative impact in the quality of life of elderly.

    Full Text Available BACKGROUND Low-back pain is the commonest condition encountered day in and day out of an orthopaedic practice. Incidence of spondylolisthesis in normal population is around 5-7%. No matter what the aetiology is, patient has significant functional disability. OBJECTIVES To study the efficacy of pedicular screw rod system and posterolateral fusion with bone substitutes in spondylolisthesis, and to study the complications associated with this treatment modality. METHODOLOGY From July 2012 to September 2014, a total of 30 patients operated with posterolateral fusion were followed up and evaluated based on VAS for low back pain and Japanese orthopaedic association scoring system. RESULTS The mean difference between pre-operative and post-operative VAS score is 3SD with a p value of <0.001, which is strongly significant. The pre-operative and post-operative JOA score has an improvement of 73.4% with a p value of <0.001, which is strongly significant. Rate of improvement was excellent in 16.7%, good in 53.3%, fair in 23.3% and poor in 6.3% of patients; 82% of patients had bone fusion by the end of 8 months. CONCLUSION Pedicular screw rod system with postero-lumbar fusion with bone substitute is safe, promising and appealing technique for low-grade spondylolisthesis with early post-operative pain relief.

    One of the most common indications for performing magnetic resonance (MR) imaging of the lumbar spine is the symptom complex thought to originate as a result of degenerative disk disease. MR imaging, which has emerged as perhaps the modality of choice for imaging degenerative disk disease, can readily demonstrate disk pathology, degenerative endplate changes, facet and ligamentous hypertrophic changes, and the sequelae of instability. Its role in terms of predicting natural history of low back pain, identifying causality, or offering prognostic information is unclear. As available modalities for imaging the spine have progressed from radiography, myelography, and computed tomography to MR imaging, there have also been advances in spine surgery for degenerative disk disease. These advances are described in a temporal context for historical purposes with a focus on MR imaging's history and current state. (orig.)

    Full Text Available Retinal degenerative diseases are major causes of vision loss and blindness worldwide and are characterized by chronic and progressive neuronal loss. One common feature of retinal degenerative diseases and brain neurodegenerative diseases is chronic neuroinflammation. There is growing evidence that retinal microglia, as in the brain, become activated in the course of retinal degenerative diseases, having a pivotal role in the initiation and propagation of the neurodegenerative process. A better understanding of the events elicited and mediated by retinal microglia will contribute to the clarification of disease etiology and might open new avenues for potential therapeutic interventions. This review aims at giving an overview of the roles of microglia-mediated neuroinflammation in major retinal degenerative diseases like glaucoma, age-related macular degeneration, and diabetic retinopathy.

    Full Text Available Background: Lumbar fusion is a proven treatment for chronic lower back pain (LBP in the setting of symptomatic spondylolisthesis and degenerative scoliosis; however, fusion is controversial when the primary diagnosis is degenerative disc disease (DDD. Our objective was to evaluate the safety and effectiveness of lumbar fusion in the treatment of LBP due to DDD. Materials and Methods: Two-hundred and five consecutive patients with single or multi-level DDD underwent lumbar decompression and instrumented fusion for the treatment of chronic LBP between the years of 2008 and 2011. The primary outcome measures in this study were back and leg pain visual analogue scale (VAS, patient reported % resolution of preoperative back pain and leg pain, reoperation rate, perioperative complications, blood loss and hospital length of stay (LOS. Results: The average resolution of preoperative back pain per patient was 84% (n = 205 while the average resolution of preoperative leg pain was 90% (n = 190 while a mean follow-up period of 528 days (1.5 years. Average VAS for combined back and leg pain significantly improved from a preoperative value of 9.0 to a postoperative value of 1.1 (P ≤ 0.0001, a change of 7.9 points for the cohort. The average number of lumbar disc levels fused per patient was 2.3 (range 1-4. Median postoperative LOS in the hospital was 1.2 days. Average blood loss was 108 ml perfused level. Complications occurred in 5% of patients (n = 11 and the rate of reoperation for symptomatic adjacent segment disease was 2% (n = 4. Complications included reoperation at index level for symptomatic pseudoarthrosis with hardware failure (n = 3; surgical site infection (n = 7; repair of cerebrospinal fluid leak (n = 1, and one patient death at home 3 days after discharge. Conclusion: Lumbar fusion for symptomatic DDD can be a safe and effective treatment for medically refractory LBP with or without leg pain.

    To evaluate the short-term and long-term effects of fluoroscopically guided caudal epidural steroid injection (ESI) for the management of degenerative lumbar spinal stenosis (DLSS) and to analyze outcome predictors. All patients who underwent caudal ESI in 2006 for DLSS were included in the study. Response was based on chart documentation (aggravated, no change, slightly improved, much improved, no pain). In June 2009 telephone interviews were conducted, using formatted questions including the North American Spine Society (NASS) patient satisfaction scale. For short-term and long-term effects, age difference was evaluated by the Mann-Whitney U test, and gender, duration of symptoms, level of DLSS, spondylolisthesis, and previous operations were evaluated by Fisher's exact test. Two hundred and sixteen patients (male: female = 75:141; mean age 69.2 years; range 48{proportional_to}91 years) were included in the study. Improvements (slightly improved, much improved, no pain) were seen in 185 patients (85.6%) after an initial caudal ESI and in 189 patients (87.5%) after a series of caudal ESIs. Half of the patients (89/179, 49.8%) replied positively to the NASS patient satisfaction scale (1 or 2). There were no significant outcome predictors for either the short-term or the long-term responses. Fluoroscopically guided caudal ESI was effective for the management of DLSS (especially central canal stenosis) with excellent short-term and good long-term results, without significant outcome predictors.

  19. Etiology, pathophysiology and conservative management of degenerative joint disease

    Full Text Available Etiology of degenerative joint diseases Etiology of degenerative joint diseases is still not clearly understood and there is no specific management for this group of diseases. Various pathological conditions cause damage of the articular cartilage and lead to clinically and radiographically recognized impairment. Biomechanical, metabolic, genetic factors inflammation and other risk factors contribute to development of osteoarthrosis. Pathophysiology of degenerative joint diseases Osteoarthrosis is characterized by progressive erosion of articular cartilage and bone overgrowth at the joint margins. Cartilage integrity requires balance between synthesis and degradation of matrix components. Chondrocytes react to various mechanical and chemical stresses in order to stabilize and restore the tissue. Failures in stabilizing and restoring the tissue lead to cartilage degeneration that may be irreversibile. For better understanding of conservative management of degenerative joint diseases it is important to know the impact of pathophysiology mechanisms on development of degenerative joint diseases. There is great variability in the rate of progression of erosive processes in articular cartilage in clinical radiographic signs and course of the disease. This is in relation with many factors, as well as with management and response to therapy. Treatment of degenerative joint diseases Treatment should vary depending on the severity of disease and patient's expectations and level of activity. Besides analgesic and anti-inflammatory drugs, conventional and not conventional treatment and techniques can be used for management of osteoarthrosis. Physical therapy and exercises are very important for maintaining muscle strength, joint stability and mobility, but should be closely monitored for optimal efficacy.

    Spondylolysis and spondylolisthesis grade 0, 1, and 2 are mainly asymptomatic but with aging process and different factors some back pain can occur and lead to chronic low back pain. The conservative treatment with physiotherapy and steroid injection is the gold standard but in some cases is not efficient enough and a surgical treatment is proposed. The goal of this study is to propose a new technique to treat grade 0, 1, and 2 spondylolisthesis with an anterior video-assisted fusion and stabilization. Twenty patients with chronic low back pain since more than 2 years and resistant to conservative therapy were included in this protocol. Clinical signs and radicular pain were noted. They were evaluated preoperatively and postoperatively until the last follow up using Oswestry score and visual analog score (VAS) for leg and back pain. X-rays showed grade 0 (8 cases), 1 (10 cases), and 2 (2 cases) spondylolisthesis according to Meyerding classification with disc collapse (bulging disc). MRI showed in all cases a disc degeneration with at least black disc and/or endplates changes with Modic I or II. All patients were operated using an anterior video-assisted retroperitoneal approach, with discectomy and fusion using an anterior impacted cage filled with autologous cancellous bone from the iliac crest and an anterior fixation with a triangular plate (Pyramid, Medtronic, Memphis). The follow up at 3, 6, 12, and 24 months was done with clinical and radiologic evaluation. In case of problem a computed tomography scan was performed. There were 11 women and 9 men, with and average age of 39 years old and a BMI of 25.6. All spondylolistheses occurred at level L5. The average slippage was 19%. All L5S1 discs were black, 8 had a Modic I changes in the endplates and 2 had Modic II. The shape of L5 vertebra was abnormal (trapezoidal) in 7 cases. All anterior approaches were performed without vascular, urologic, or digestive complication. Blood loss was inferior to 100 mL. All

    Full Text Available This study was used to evaluate the degenerative effects on the retina and eye-cup sections after experimental induction of acute ocular hypertension on animal models. In particular, vascular events were directly focused in this research in order to assess the vascular remodeling after transient ocular hypertension on rat models. After local anaesthesia by administration of eye drops of 0.4% oxibuprocaine, 16 male adult Wistar rats were injected in the anterior chamber of the right eye with 15 µL of methylcellulose (MTC 2% in physiological solution. The morphology and the vessels of the retina and eye-cup sections were examined in animals sacrificed 72 h after induction of ocular hypertension. In retinal fluorescein angiographies (FAGs, by means of fluorescein isothiocyanate-coniugated dextran (FITC, the radial venules showed enlargements and increased branching, while the arterioles appeared focally thickened. The length and size of actually perfused vessels appeared increased in the whole superficial plexus. In eye-cup sections of MTC-injected animals, in deep plexus and connecting layer there was a bigger increase of vessels than in controls. Moreover, the immunolocalization of astrocytic marker glial fibrillary acidic protein (GFAP revealed its increased expression in internal limiting membrane and ganglion cell layer, as well as its presence in Müller cells. Finally, the pro-angiogenic factor vascular endothelial growth factor (VEGF was found to be especially expressed by neurones of ganglion cell layer, both in control and in MTC-injected eyes. The data obtained in this experimental model on the interactions among glia, vessels and neurons should be useful to evaluate if also in glaucomatous patients the activation of vessel-adjacent glial cells might play key roles in following neuronal dysfunction.

  2. Management of degenerative cervical myelopathy – An update

    Directory of Open Access Journals (Sweden)

    ANDREI F. JOAQUIM

    Full Text Available SUMMARY Introduction Degenerative cervical myelopathy (DCM is the most common cause of spinal cord dysfunction in adult patients. Patients generally present with a slow, progressive neurological decline or a stepwise deterioration pattern. In this paper, we discuss the most important factors involved in the management of DCM, including a discussion about the surgical approaches. Method The authors performed an extensive review of the peer-reviewed literature addressing the aforementioned objectives. Results Although the diagnosis is clinical, magnetic resonance imaging (MRI is the study of choice to confirm stenosis and also to exclude the differential diagnosis. The severity the clinical symptoms of DCM are evaluated by different scales, but the modified Japanese Orthopedic Association (mJOA and the Nürick scale are probably the most commonly used. Spontaneous clinical improvement is rare and surgery is the main treatment form in an attempt to prevent further neurological deterioration and, potentially, to provide some improvement in symptoms and function. Anterior, posterior or combined cervical approaches are used to decompress the spinal cord, with adjunctive fusion being commonly performed. The choice of one approach over the other depends on patient characteristics (such as number of involved levels, site of compression, cervical alignment, previous surgeries, bone quality, presence of instability, among others as well as surgeon preference and experience. Conclusion Spine surgeons must understand the advantages and disadvantages of all surgical techniques to choose the best procedure for their patients. Further comparative studies are necessary to establish the superiority of one approach over the other when multiple options are available.

    A review of the imaging features of normal and degenerative anatomy of the spine on medical imaging studies shows features that have been largely overlooked or poorly understood by the imaging community in recent years. The imaging methods reviewed included computed tomography (CT) with multiplanar reconstructions and magnetic resonance imaging (MRI). A routine part of the MRI examination included fat-suppressed T2 weighted fast-spin- or turbo-spin-echo acquisitions. As compared to the normal features in asymptomatic volunteers, alterations in the observed CT/MRI morphology and MR signal characteristics were sought in symptomatic individuals. Findings in symptomatic subjects which departed from the normal anatomic features of the posterior spinal elements in asymptomatic volunteers included: rupture of the interspinous ligament(s), neoarthrosis of the interspinous space with perispinous cyst formation, posterior spinal facet (zygapophyseal joint) arthrosis, related central spinal canal, lateral recess (subarticular zone) and neural foramen stenosis, posterior element alterations associated with various forms of spondylolisthesis, and perispinal muscle rupture/degeneration. These findings indicate that the posterior elements are major locations of degenerative spinal and perispinal disease that may accompany or even precede degenerative disc disease. Although not as yet proven as a reliable source of patient signs and symptoms in all individuals, because these observations may be seen in patients with radicular, referred and/or local low back pain, they should be considered in the evaluation of the symptomatic patient presenting with a clinical lumbosacral syndrome. Imaging recommendations, in addition to the usual close scrutiny of these posterior spinal elements and perispinal soft tissues on CT and MRI, include the acquisition of high-resolution multiplanar CT reconstructions, and fat-suppressed T2 weighted fast-spin- or turbo-spin-echo sequence MRI in at least

    A 24-year-old male patient was initially evaluated for persistent back pain. The visual analogue scale (VAS) score was 7 points. Physical examination revealed a decreased range of lumbar spinal motion, which caused pain. Simple X-ray revealed Meyerding grade 1 spondylolisthesis at L4 on L5, with mild dome-shaped superior endplate and consecutive multilevel spondylolysis at T12-L5. Standing anteroposterior and lateral views of the entire spine revealed normal balance of sagittal and coronal alignment. A computed tomography scan revealed bilateral spondylolysis at T12-L4, left unilateral spondylolysis at L5, and spina bifida at L5 to sacral region. Magnetic resonance imaging revealed mild dural ectasia at the lumbar region. Due to the absence of any neurological symptoms, the patient was managed conservatively. He was rested a few weeks with corset brace and physiotherapy. After treatment, his back pain improved, VAS score changed from 7 to 2, and he was able to return to normal activity.

    Objective To analyze complications associated with posterior lumbar interbody fusion (PLIF) in which two Bagby and Kuslich (BAK) interbody fusion cages were implanted.Methods A total of 118 patients with spondylolytic spondylolisthesis underwent single-level PLIF using two BAK cages filled with morselized autogenous bone. The major clinical and radiographic complications were analyzed after a follow-up with an average time of 2 years and 9 months.Results Complications were divided into intraoperative and postoperative complications. Intraoperative complications mainly included dural tear (4 patients, 3.4%), nerve root injury (3 patients, 2.5%) and suboptimal cage position (9 patients, 7.5%). No death was caused by the operation. Postoperative complications chiefly consisted of cage retropulsion (3 patients, 2.5%), cage subsidence (4 patients, 3.4%), and postlaminectomy arachnoiditis (2 patients, 1.7%). Pseudarthrosis was noted radiographically with evidence of motion between adjacent vertebra on lateral flexion-extension films and luciencies around the cages (2 patient, 1.7%), continuous posterior cage migration (2 patients, 1.7%) or continuous cage subsidence (2 patients, 1.7%). Two patients died, one from a traffic accident and the other from metastatic cancer 1 year postoperatively.Conclusions The results of this study indicate that PLIF with BAK cages is an effective but also technically difficult procedure. The relatively high incidence of complications reminds us of the importance of surgical indications and proper manipulations.

    Nontraumatic spinal epidural hematoma (SEH) is a rare condition and the exact cause of the hemorrhage in SEH had never been established. However, there have been a few recent reports on some types of the epidural hematoma with a detectable origin of hemorrhage. We encountered a case of chronic SEH in a patient who had spondylolytic spondylolisthesis, which is also a rare condition to be associated with SEH. We report here on the radiologic findings of a case of chronic epidural hematoma in a patient who had spondylolytic spondylolisthesis at the L4-5 level, and we include a review of the related literatures.

    Degenerative disease of the spine, in the form of intervertebral disc degeneration and bony growth, causing osteophytes and impinging upon the spinal canal and neural foramina, is the most frequent disorder affecting the spine. In this chapter we first discuss briefly the indications for computed tomography or magnetic resonance imaging in suspected degenerative spine disease. We then describe changes of disc height, signal intensity, and disc contour with aging and repeated microtrauma, as well as the imaging techniques most appropriate to image them. A grading system for lumbar disc changes is provided. Stenosis of the canal and neural foramina is reviewed next, concluding with a description of degenerative changes affecting the vertebral endplates and bone marrow.

    Degenerative articular disk perforations of the triangular fibrocartilage (TFC) of the wrist could result from chronic loading of the ulnocarpal joint. Apoptosis played a crucial role in fibrocartilage cell loss, and the purpose of this study was to clarify which apoptotic pathway was involved in the development of degenerative disk lesions. We also investigated whether ulna length played an etiologic role in the occurrence of fibrocartilage cell loss. Included in the study were 17 patients with degenerative articular disk tears of the TFC (Palmer type 2C). After arthroscopic debridement of the TFC, histologic sections were examined to assess the presence of apoptosis. Apoptosis was determined by use of caspase 3, caspase 8, and caspase 9 immunohistochemistry. Furthermore, Fas ligand and BID (BH3 interacting domain death) agonist were applied for immunohistochemical analysis. Cells positive for caspase 3, caspase 8, caspase 9, Fas ligand, and BID were found in all specimens. The number of cells positive for caspase 3 and BID was significantly increased in specimens from patients with an ulna-positive variance. In contrast, for cells positive for caspase 8, caspase 9, and Fas ligand, no significant difference was found between specimens from patients with an ulna-positive variance and those from patients with an ulna-neutral/ulna-negative variance. The extrinsic and intrinsic apoptotic pathways are involved in the development of degenerative disk lesions. Fibrocartilage cell loss occurs mainly through the intrinsic apoptotic pathway. The accumulation of apoptotic cells is not significantly different between the 3 zones of the TFC. It could be verified that ulna length is correlated with fibrocartilage cell loss. Ulnar shortening is a valuable treatment option for degenerative TFC lesions. Knowledge of the specific apoptotic pathway that is causing degenerative disk lesions is critical in selecting the appropriate and most beneficial therapeutic treatment to halt

  13. OUTCOME OF POSTEROLATERAL FUSION VERSUS CIRCUMFERENTIAL FUSION WITH CAGE FOR LUMBAR STENOSIS AND LOW DEGREE LUMBAR SPONDYLOLISTHESIS

    2006-01-01

    Objective To evaluate the outcome of two methods for stabilization and fusion: posterolateral fusion and circumferential fusion involving posterior lumbar interbody fusion for lumbar stenosis with Grades 1 and 2 lumbar spondylolisthesis. Methods From April 1998 to April 2003, 45 patients suffering from lumbar stenosis with low degree lumbar spondylolisthesis treated in our hospital were retrospectively reviewed and assigned to two groups. Among them, 24 patients (group A) were treated with instrumented posterolateral fusion and 21 patients (group B) with instrumented circumferential fusion. The two groups were compared for clinical and radiological outcomes. Results All patients were followed up for 12 to 72 months. In group A, results showed preoperative clinical symptoms disappeared completely in 12 of 24 patients, and pain relief was seen in 91.7% (22/24). Two cases suffered from residual symptoms. Twenty-two cases obtained complete reduction of olisthy vertebral bodies, and anatomical reduction rate was 91.7%. No infection or neurological complication occurred in this group. In group B, results showed preoperative clinical symptoms disappeared completely in 13 of 21 patients, and pain relief was seen in 90. 5% ( 19/21 ). One case suffered from residual symptoms. Twenty cases obtained complete reduction of the olisthy vertebral bodies, and anatomical reduction rate was 95.2%. Four cases of infection or neurological complication occurred in this group. Both groups indicated no significant difference in clinical outcomes and anatomical reduction rate during followup. But group A had better intraoperative circumstances and postoperative outcome than group B, while group B had better postoperative parameters in X-ray of Angle of Slipping and Disc Index than group A.Conclusions The first choice of surgical method for lumbar stenosis with low degree lumbar spondylolisthesis is instrumented posterolateral fusion. Only when patients suffer from severe preoperative disc

    The uncommon variant of degenerative hip joint disease, termed rapidly progressive osteoarthritis, and highlighted by severe joint space loss and osteochondral disintegration, is well established. We present a similar unusual subset in the lumbar spine termed destructive discovertebral degenerative disease (DDDD) with radiological features of vertebral malalignment, severe disc resorption, and "bone sand" formation secondary to vertebral fragmentation. Co-existing metabolic bone disease is likely to promote the development of DDDD of the lumbar spine, which presents with back pain and sciatica due to nerve root compression by the "bone sand" in the epidural space. MRI and CT play a complimentary role in making the diagnosis.

  15. Limited access surgery for 360 degrees in-situ fusion in a dysraphic patient with high-grade spondylolisthesis.

    König, M A; Boszczyk, B M

    2012-03-01

    Progressive high-grade spondylolisthesis can lead to spinal imbalance. High-grade spondylolisthesis is often reduced and fused in unbalanced pelvises, whereas in-situ fusion is used more often in balanced patients. The surgical goal is to recreate or maintain sagittal balance but if anatomical reduction is necessary, the risk of nerval damage with nerve root disruption in worst cases is increased. Spinal dysraphism like spina bifida or tethered cord syndrome make it very difficult to achieve reduction and posterior fusion due to altered anatomy putting the focus on anterior column support. Intensive neural structure manipulation should be avoided to reduce neurological complications and re-tethering in these cases. A 26-year-old patient with a history of diastematomyelia, occult spina bifida and tethered cord syndrome presented with new onset of severe low back pain, and bilateral L5/S1 sciatica after a fall. The X-ray demonstrated a grade III spondylolisthesis with spina bifida and the MRI scan revealed bilateral severely narrowed exit foramina L5 due to the listhesis. Because she was well balanced sagittally, the decision for in-situ fusion was made to minimise the risk of neurological disturbance through reduction. Anterior fusion was favoured to minimise manipulation of the dysraphic neural structures. Fusion was achieved via isolated access to the L4/L5 disc space. A L5 transvertebral hollow modular anchorage (HMA) screw was passed into the sacrum from the L4/L5 disc space and interbody fusion of L4/L5 was performed with a cage. The construct was augmented with pedicle screw fixation L4-S1 via a less invasive bilateral muscle split for better anterior biomechanical support. The postoperative course was uneventful and fusion was CT confirmed at the 6-month follow-up. At the last follow-up, she worked full time, was completely pain free and not limited in her free-time activities. The simultaneous presence of high-grade spondylolisthesis and spinal dysraphism

    Lumbar degenerative kyphosis (LDK) is a subgroup of the flat-back syndrome and is most commonly caused by unique life styles, such as a prolonged crouched posture during agricultural work and performing activities of daily living on the floor. Unfortunately, LDK has been used as a byword for degenerative sagittal imbalance, and this sometimes causes confusion. The aim of this review was to evaluate the exact territory of LDK, and to introduce another appropriate term for degenerative sagittal deformity. Unlike what its name suggests, LDK does not only include sagittal balance disorder of the lumbar spine and kyphosis, but also sagittal balance disorder of the whole spine and little lordosis of the lumbar spine. Moreover, this disease is closely related to the occupation of female farmers and an outdated Asian life style. These reasons necessitate a change in the nomenclature of this disorder to prevent misunderstanding. We suggest the name “primary degenerative sagittal imbalance” (PDSI), which encompasses degenerative sagittal misalignments of unknown origin in the whole spine in older-age patients, and is associated with back muscle wasting. LDK may be regarded as a subgroup of PDSI related to an occupation in agriculture. Conservative treatments such as exercise and physiotherapy are recommended as first-line treatments for patients with PDSI, and surgical treatment is considered only if conservative treatments failed. The measurement of spinopelvic parameters for sagittal balance is important prior to deformity corrective surgery. LDK can be considered a subtype of PDSI that is more likely to occur in female farmers, and hence the use of LDK as a global term for all degenerative sagittal imbalance disorders is better avoided. To avoid confusion, we recommend PDSI as a newer, more accurate diagnostic term instead of LDK. PMID:28264231

    Degenerative cysts of the lumbar spine encompass a heterogeneous group of cystic lesions that are presumed to share a common aetiology. Some of these cysts may be incidental findings, whereas others may produce acute or chronic symptoms. These cysts have been categorized using various combinations of topographic and pathological characteristics and by their attachment to or communication with a specific spinal structure.

    The present study aimed to evaluate the early effects of interspinous spacers on lumbar degenerative disease. The clinical outcomes of 23 patients with lumbar degenerative disease, treated using interspinous spacer implantation alone or combined with posterior lumbar fusion, were retrospectively studied and assessed with a visual analogue scale (VAS) and the Oswestry Disability Index (ODI). Pre-operative and post-operative interspinous distance, disc space height, foraminal width and height and segmental lordosis were determined. The early effects and complications associated with the interspinous spacers were recorded. The surgical procedures performed with the in-space treatment were easy and minimally invasive. The VAS scores and ODI were improved post-operatively compared with pre-operatively. Significant changes in the interspinous distance, disc space height, foraminal width and height and segmental lordosis were noted. In-space treatment for degenerative lumbar disease is easy and safe, with good early effects. The in-space system provides an alternative treatment for lumbar degenerative disease.

    The DNA damage response (DDR) is a complex biological system activated by different types of DNA damage. Mutations in certain components of the DDR machinery can lead to geno-mic instability disorders that culminate in tissue degeneration, premature aging, and various types of cancers. Intriguingly, malfunctioning DDR plays a role in the etiology of late onset brain degener-ative disorders such as Parkinson’s, Alzheimer’s, and Huntington’s diseases. For many years, brain degenerative disorders were thought to result from aberrant neural death. Here we discuss the evi-dence that supports our novel hypothesis that brain degenerative diseases involve dysfunction of glial cells (astrocytes, microglia, and oligodendrocytes). Impairment in the functionality of glial cells results in pathological neuro-glial interactions that, in turn, generate a‘‘hostile”environment that impairs the functionality of neuronal cells. These events can lead to systematic neural demise on a scale that appears to be proportional to the severity of the neurological deficit.

    2015-06-01

    Full Text Available Background: Treatment by posterolateral fusion (PLF with pedicle-screw instrumentation can be unsuccessful in one-segment and low-grade lumbar spondylolisthesis. Segmental kyphosis, either rigid or dynamic, was hypothesized to be one of the factors interfering with the fusion results. Methods: From 2004 to 2005, 239 patients with single-segment and low-grade spondylolisthesis were recruited and divided into two groups: Group 1 consisting of 129 patients without segmental kyphosis and group 2 consisting of 110 patients with segmental kyphosis. All patients underwent instrumented PLF at the same medical institute, and the average follow-up period was 31 ± 19 months. We obtained plain radiographs of the lumbosacral spine with the anteroposterior view, the lateral view, and the dynamic flexion-extension views before the operation and during the follow-ups. The results of PLF in the two groups were then compared. Results: There was no significant difference in the demographic data of the two groups, except for gender distribution. The osseous fusion rates were 90.7% in group 1 and 68.2% in group 2 (p < 0.001. Conclusion: Instrumented PLF resulted in significantly higher osseous fusion rate in patients without segmental kyphosis than in the patients with segmental kyphosis. For the patients with sagittal imbalance, such as rigid or dynamic kyphosis, pedicle-screw fixation cannot ensure successful PLF. Interbody fusion by the posterior lumbar interbody fusion or transforaminal lumbar interbody fusion technique might help overcome this problem.

    Physiotherapeutic management of patients immediately following lumbar spinal surgery is common. However, there is considerable variability in the interventions provided. To assess the effect of peri-operative physiotherapeutic intervention in adults undergoing surgery for the management of degenerative lumbar conditions. The Cochrane Library, Medline, Embase, CINAHL and PEDro were searched from inception to August 2012. Randomised controlled trials investigating physiotherapeutic interventions prior to and immediately following surgery for degenerative lumbar conditions were included. Two reviewers extracted data independently using a standardised form. Risk of bias was assessed using a modified version of the Cochrane Collaboration tool. The quality of evidence was assessed using the GRADE approach, and the treatment effect size was calculated where comparable outcome measures were used across multiple trials. Four studies were included. There is very-low-quality evidence that pre- and post-operative exercise in addition to standard physiotherapeutic care may reduce pain, time taken to achieve post-operative functional milestones, and post-operative time off work. Results from one study indicated that there is no clear benefit or risk of harm from performing either prone or side-lying transfers. Very-low-quality evidence suggests that physiotherapy may improve pain and function following lumbar surgery. Due to low numbers of included studies and variation in the interventions assessed, the current evidence provides limited guidance for physiotherapeutic practice. Further research is required to determine the effectiveness of physiotherapeutic interventions in this population. Copyright © 2014 Chartered Society of Physiotherapy. Published by Elsevier Ltd.

    2005-01-01

    The role of surgical correction of sagittal plane deformity in cases of lytic spondylolisthesis remains controversial. While some early evidence is emerging of the possible short- and long-term benefits of restoring spinal balance, many surgeons have been concerned about the associated risks. The insert-and-rotate posterior lumbar interbody fusion (PLIF) technique, first described by Jaslow in 1946, may enable surgeons to safely and effectively correct sagittal balance through a single posterior approach. To determine whether the focal kyphosis and subluxation associated with a lytic lumbosacral spondylolisthesis can be safely and effectively corrected using a single-stage posterior distraction/reduction technique and insert-and-rotate interbody fusion spacers. A prospective, single cohort, observational study of the clinical outcomes and retrospective radiological review, in a series of 18 consecutive patients with lytic spondylolisthesis Grades I to IV, operated between September 2000 and December 2002. Mean age of 50.2 years (range, 15.5 to 77.8 years). Principal indication for surgery was relief of radicular pain secondary to foraminal stenosis in 16 of 18 patients, and back pain was the principal symptom in 2 patients. Mean preoperative slip was 30.2% (range, 9% to 78%). Mean preoperative focal lordosis was 10.6 degrees (range, -12 to 33 degrees). Minimum 12-month follow-up was available on all patients except one, who died of unrelated causes after his 6-month visit. Patients completed Visual Analogue Pain Score (VAS), Low Back Outcome Score (LBOS), Short Form (SF)-12 and patient satisfaction questionnaires. Pre- and postoperative measurements of the percentage slip and lumbar lordosis of the involved segments were available on 13 patients. SURGICAL METHODS: Decompressive laminectomy was followed by reduction of the spondylolisthesis with the aid of intervertebral disc space spreaders and supplementary pedicle screw instrumentation. The vertebral bodies were

    Idiopathic Parkinson's disease (PD) and Alzheimer's disease (AD) are the main neuro-degenerative diseases (NDDs) seen clinically. They share some common clinical symptoms and neuro-pathological findings. The increase of life expectancy in the developed countries will inevitably contribute to enhance the prevalence of these diseases. Behavioral disorders, common in NDDs, will produce major care management challenges. Idiopathic Parkinson's disease corresponds to a histopathological diagnosis, based on the observation of a de-pigmentation and a neuronal loss in the substantia nigra, as well as on the presence of intra-neuronal inclusion bodies. AD is insidious with slowly progressive dementia in which the decline in memory constitutes the main complaint. The diagnosis of definite AD requires the presence of clinical criteria as well as the histopathological confirmation of brain lesions. The two main lesions are the presence of senile plaques and neuro-fibrillary tangles. Positron emission tomography (PET) explores cerebral metabolism and neurotransmitter kinetics in NDDs using principally [{sup 18}F]-deoxyglucose and [{sup 18}F]-dopa. Nigrostriatal dopaminergic function is altered in PD, as evidenced by the low uptake of [{sup 18}F]-dopa in the posterior putamen as compared to anterior putamen and caudate nucleus. In contrast, [{sup 18}F]-dopa uptake is equally depressed in all striatal structures in progressive supra-nuclear palsy. Regional glucose metabolism at rest is preserved in elderly once cerebral atrophy is taken into account. On the contrary, glucose metabolism is globally reduced in AD, with marked decrease in the parietal and temporal regions. PET has proved to be useful to study in vivo neurochemical processes in patients suffering from NDDs. The potential of this approach is still largely unexploited, and depends on new ligand production to establish early diagnosis and treatment follow-up. (author)

    OBJECT Usually additional anchors into the ilium are necessary in long fusion to the sacrum for degenerative lumbar spine disorders (DLSDs), especially for adult spine deformity. Although the use of anchors is becoming quite common, surgeons must always keep in mind that the sacroiliac (SI) joint is mobile and they should be aware of the kinematic properties of the SI joint in patients with DLSDs, including adult spinal deformity. No previous study has clarified in vivo kinematic changes in the SI joint with respect to patient age, sex, or parturition status or the presence of DLSDs. The authors conducted a study to clarify the mobility and kinematic characteristics of the SI joint in patients with DLSDs in comparison with healthy volunteers by using in vivo 3D motion analysis with voxel-based registration, a highly accurate, noninvasive method. METHODS Thirteen healthy volunteers (the control group) and 20 patients with DLSDs (the DLSD group) underwent low-dose 3D CT of the lumbar spine and pelvis in 3 positions (neutral, maximal trunk flexion, and maximal trunk extension). SI joint motion was calculated by computer processing of the CT images (voxel-based registration). 3D motion of the SI joint was expressed as both 6 df by Euler angles and translations on the coordinate system and a helical axis of rotation. The correlation between joint motion and the cross-sectional area of the trunk muscles was also investigated. RESULTS SI joint motion during trunk flexion-extension was minute in healthy volunteers. The mean rotation angles during trunk flexion were 0.07° around the x axis, -0.02° around the y axis, and 0.16° around the z axis. The mean rotation angles during trunk extension were 0.38° around the x axis, -0.08° around the y axis, and 0.08° around the z axis. During trunk flexion-extension, the largest amount of motion occurred around the x axis. In patients with DLSDs, the mean rotation angles during trunk flexion were 0.57° around the x axis, 0.01

    Conversational topics chosen by a group of adults with degenerative cognitive-linguistic disorders for personalized communication board development were examined. The patient-generated themes commonly selected are presented to guide treatment planning and communication board development. Communication boards were created for 109 adults as part of a larger research project. One autobiographical topic that each participant would enjoy discussing multiple times was represented on each communication board with 16 pictures and word labels. For this review, topics were collapsed into general themes through a consensus process and examined by gender and age. Sixty unique conversational topics were identified from 109 participants and collapsed into 9 general themes: Hobbies, Family, Travel, Work, Home/Places I've Lived, Sports/Fitness, Religion, Animals, and World War II. Age and gender produced variations in themes chosen, though no significance in rank orders was found across groups. Topics selected by adults with degenerative cognitive-linguistic disorders for communication boards resemble common conversational adult themes and do not center around basic needs or medical issues. Differences in gender and age for topic selection tend to be based on traditional roles. These general themes should be used when creating personalized communication boards for those who benefit from conversational aids.

    The elbow joint is one of the feline appendicular joints most commonly and severely affected by degenerative joint disease. The macroscopic and histopathological lesions of the elbow joints of 30 adult cats were evaluated immediately after euthanasia. Macroscopic evidence of degenerative joint disease was found in 22 of 30 cats (39 elbow joints) (73.33% cats; 65% elbow joints), and macroscopic cartilage erosion ranged from mild fibrillation to complete ulceration of the hyaline cartilage with exposure of the subchondral bone. Distribution of the lesions in the cartilage indicated the presence of medial compartment joint disease (most severe lesions located in the medial coronoid process of the ulna and medial humeral epicondyle). Synovitis scores were mild overall and correlated only weakly with macroscopic cartilage damage. Intra-articular osteochondral fragments either free or attached to the synovium were found in 10 joints. Macroscopic or histologic evidence of a fragmented coronoid process was not found even in those cases with intra-articular osteochondral fragments. Lesions observed in these animals are most consistent with synovial osteochondromatosis secondary to degenerative joint disease. The pathogenesis for the medial compartmentalization of these lesions has not been established, but a fragmented medial coronoid process or osteochondritis dissecans does not appear to play a role. © The Author(s) 2014.

    Objective To determine whether the synthesis of proteoglycan, collagen and associated ultrastructure are related to the adenovirus-mediated gene transferred to adult degenerative cells.Methods Adenovirus/cytomegalovirus human transforming growth fector-β1 (Ad/CMV-hTGF-β1) was used to transfect degenerative cells. Antonopulos method, Miamine method and transmission electrion microscopy were conducted to study the synthesis of proteoglycan, collagen, and ultrastructure, respectively. Cell cultures were established from the nucleus pulpous and annulus fibrosus tissues, which were taken from surgery.Results Nucleus pulpous and annulus fibrosus cells were efficiently transduced by the adenoviral vector carrying hTGF-β1 gene. The synthesis of proteoglycan and collagen increased compared with the control group (P<0.05). The metabolism of cells was slightly improved. No significant toxic effects were found.Conclusions Expression of hTGF-β1 gene is efficient to accelerates proteoglycan synthesis and thus accelerates the improvement of collagen. The function and structure of degenerative cells are improved. Ad/CMV-hTGF-β1 may be suitable for treating disc degeneration.

    Hardly any other structure in the human body is held responsible for so many complaints, pain, and costs as the spine and its degenerative disorders. In the following article, the role of imaging procedures in diagnosing disorders of the spine is presented. Due to the fact that disk herniation represents the most frequent cause for degenerative disorders the anatomy of the intervertebral disk and the pathology of the entities that can cause diseases of the disks are described. In particular, the authors focus on the significance of radiological findings with respect to patient history, subjective symptoms, and objective clinical findings. In addition to presenting the technical procedures and their indications and contraindications also practical tips and tricks in conducting these examinations are presented in this paper.

    Background Sagittal balance restoration has been shown to be an important determinant of outcomes in corrective surgery for degenerative scoliosis. Lateral interbody fusion (LIF) is a less-invasive technique which permits the placement of a high lordosis interbody cage without risks associated with traditional anterior or transforaminal interbody techniques. Studies have shown improvement in lumbar lordosis following LIF, but only one other study has assessed sagittal balance in this population. The objective of this study is to evaluate the ability of LIF to restore sagittal balance in degenerative lumbar scoliosis. Methods Thirty-five patients who underwent LIF for degenerative thoracolumbar scoliosis from July 2013 to March 2014 by a single surgeon were included. Outcome measures included sagittal balance, lumbar lordosis, Cobb Angle, and segmental lordosis. Measures were evaluated pre-operative, immediately post-operatively, and at their last clinical follow-up. Repeated measures ANOVAs were used to assess the differences between pre-operative, first postoperative, and a follow-up visit. Results The average sagittal balance correction was not significantly different: 1.06cm from 5.79cm to 4.74cm forward. The average Cobb angle correction was 14.1 degrees from 21.6 to 5.5 degrees. The average change in global lumbar lordosis was found to be significantly different: 6.3 degrees from 28.9 to 35.2 degrees. Conclusions This study demonstrates that LIF reliably restores lordosis, but does not significantly improve sagittal balance. Despite this, patients had reliable improvement in pain and functionality suggesting that sagittal balance correction may not be as critical in scoliosis correction as previous studies have indicated. Clinical Relevance LIF does not significantly change sagittal balance; however, clinical improvement does not seem to be contingent upon sagittal balance correction in the degenerative scoliosis population. The DUHS IRB has determined this

    We retrospectively reviewed patient charts to compare the approach-related (convex versus concave) neurological complications and magnitude of correction in patients undergoing lateral lumbar interbody fusion (LLIF). It is yet to be quantitatively determined if correction of adult degenerative scoliosis from either side of the curve apex using a LLIF results in a reduction in complications and/or improved corrective ability. The inclusion criteria for this study were patients who underwent a LLIF for adult degenerative thoracolumbar scoliosis and had the LLIF prior to any other supplemental procedures. Patients were grouped based on the approach toward the curve apex concavity (CAVE) or the convexity (VEX). Standard coronal and sagittal radiographic measurements were made. Neurological complications and reoperation indications were also recorded. We included 32 patients for review (CAVE: 17; VEX: 15) with a mean age of 65.5 years±a standard deviation of 10.2, and mean follow-up of 17.0 months±15.7. There were eight postoperative neurological complications in eight patients (25.0%), and seven reoperations for six patients (18.8%; CAVE: 4/17 [23.5%]; VEX: 2/15 [13.3%]). The CAVE group had 6/17 neurological complications (35.3%; four ipsilateral and two contralateral to approach side) and VEX had 2/15 (13.3%; one ipsilateral and one bilateral to approach side; p>0.05). All patients significantly improved in the mean regional and segmental Cobb angles (p0.05). There were no significant differences between the groups for any of the radiographic parameters measured (p>0.05). Approaching the curve apex from either the concave or convex side resulted in significant improvements. The concave approach was associated with more postoperative neurological complications.

  17. MR imaging of the spine: trauma and degenerative disease

    1999-09-01

    The purpose of this paper is to discuss the capabilities and drawbacks of MR imaging in patients with trauma to the spine and degenerative spinal conditions. In spinal trauma MR imaging is secondary to plain X-ray films and CT because of the greater availability and ease of performance of these techniques and their superior capability for detecting vertebral fractures. Magnetic resonance imaging is useful for detecting ligamentous ruptures and intraspinal mass lesions such as hematoma, and for assessing the state of the spinal cord and prognosis of a cord injury. In degenerative spinal disease the necessity is emphasized of critically evaluating the clinical relevance of any abnormal feature detected, as findings of degenerative pathology are common in individuals without symptoms. Magnetic resonance myelography permits rapid and accurate assessment of the state of the lumbar nerve roots (compressed or not). In the cervical region the quality of the myelographic picture is often degraded in patients with a narrow spinal canal. (orig.) With 10 figs., 14 refs.

    Full Text Available The DNA damage response (DDR is a complex biological system activated by different types of DNA damage. Mutations in certain components of the DDR machinery can lead to genomic instability disorders that culminate in tissue degeneration, premature aging, and various types of cancers. Intriguingly, malfunctioning DDR plays a role in the etiology of late onset brain degenerative disorders such as Parkinson’s, Alzheimer’s, and Huntington’s diseases. For many years, brain degenerative disorders were thought to result from aberrant neural death. Here we discuss the evidence that supports our novel hypothesis that brain degenerative diseases involve dysfunction of glial cells (astrocytes, microglia, and oligodendrocytes. Impairment in the functionality of glial cells results in pathological neuro-glial interactions that, in turn, generate a “hostile” environment that impairs the functionality of neuronal cells. These events can lead to systematic neural demise on a scale that appears to be proportional to the severity of the neurological deficit.

    OBJECTIVE In the past decade, dynamic stabilization has been an emerging option of surgical treatment for lumbar spondylosis. However, the application of this dynamic construct for mild spondylolisthesis and its clinical outcomes remain uncertain. This study aimed to compare the outcomes of Dynesys dynamic stabilization (DDS) with minimally invasive transforaminal lumbar interbody fusion (MI-TLIF) for the management of single-level spondylolisthesis at L4-5. METHODS This study retrospectively reviewed 91 consecutive patients with Meyerding Grade I spondylolisthesis at L4-5 who were managed with surgery. Patients were divided into 2 groups: DDS and MI-TLIF. The DDS group was composed of patients who underwent standard laminectomy and the DDS system. The MI-TLIF group was composed of patients who underwent MI-TLIF. Clinical outcomes were evaluated by visual analog scale for back and leg pain, Oswestry Disability Index, and Japanese Orthopaedic Association scores at each time point of evaluation. Evaluations included radiographs and CT scans for every patient for 2 years after surgery. RESULTS A total of 86 patients with L4-5 spondylolisthesis completed the follow-up of more than 2 years and were included in the analysis (follow-up rate of 94.5%). There were 64 patients in the DDS group and 22 patients in the MI-TLIF group, and the overall mean follow-up was 32.7 months. Between the 2 groups, there were no differences in demographic data (e.g., age, sex, and body mass index) or preoperative clinical evaluations (e.g., visual analog scale back and leg pain, Oswestry Disability Index, and Japanese Orthopaedic Association scores). The mean estimated blood loss of the MI-TLIF group was lower, whereas the operation time was longer compared with the DDS group (both p spondylolisthesis at L4-5. DDS might be an alternative to standard arthrodesis in mild lumbar spondylolisthesis. However, unlike fusion, dynamic implants have issues of wearing and loosening in the long term

    The patients with lumber degenerative spondylolisthesis often have to undergo surgical treatment. Conventional surgical approach is performed by bilateral pedicle screw fixation in lumbar interbody fusion, and this maybe accelerate segment degeneration of adjacent vertebral bodies. The recent studies indicate that unilateral pedicle screw fixation in lumbar interbody fusion can achieve the same effect on stability and interbody fusion by using conventional bilateral pedicle screw fixation in lumbar interbody fusion,.and prevent from segment degeneration of vertebral bodies. But the operation indication must be restrictedly controlled, the operation technique be skilled.%保守失败的腰椎退行性疾病常需要手术治疗,传统的双侧椎弓根螺钉腰椎融合术可能增加邻近节段退变的发生率。近年研究表明,单侧椎弓根螺钉结合椎体间融合术治疗腰椎退行性疾病可获得与传统双侧椎弓根螺钉固定相似的稳定性与融合率,并可预防固定融合节段的邻近节段退变,但应用单侧椎弓根螺钉固定需要严格掌握手术适应证。

    The optimal management of high-grade spondylolisthesis in children and adolescent is controversial. There is a paucity of literature regarding operatively or nonoperative management in this setting. To assessment of the current state of evidence regarding high-grade spondylolisthesis treatment with the goal of obtaining outcome comparisons in these patients managed either operatively or nonoperatively. We performed a systematic literature search up to November 2014, using Medline, Embase, and The Cochrane Library. The analysis and eligibility criteria were documented according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA-guidelines) and Cochrane Back Review Group editorial board. We used the Newcastle-Ottawa quality assessment scale (NOS-scale) to assess the quality. Five observational studies were considered eligible for analysis based on the evaluation of 1596 identified papers. The mean overall difference in the Scoliosis Research Society questionnaire 22 between the surgical and nonsurgical groups was not statistically significant (95% CI: -0.17 to 0.21, P = 0.84). The pooled mean difference in progression of slip between the surgical and nonsurgical groups was no significant difference (OR: 0.47, 95% CI: 0.12-1.81, P = 0.27, I = 0%). Because of the preponderance of uncontrolled case series, low-quality evidence indicates that the quality of life and progression of slips was no significant difference between surgery and nonoperation group. Nonoperative patients had no radiologic progression of their slip during the follow-up period.

    66 patients with spondylolisthesis were reviewed after surgical procedure with a follow-up period of more than a year postoperatively. The indication for the operation was disabling sciatica in all patients. 4 patients had undergone prior excision of the herniated disc. All the patients underwent a removal of the loose posterior element as suggested by the Gill procedure and intervertebral body fusion using a posterior surgical approach. The surgical procedures with only one regressive neurological complication are described. The results are considered from a clinical and anatomo-radiological point of view. In this series 86.5 percent of 66 patients became sciatica-free. 62 percent of the total series rated the end result as excellent or good. 92.4 percent of the patients demonstrated bony fusion between the two grafted vertebrae. The benefits of posterior laminectomy with interbody fusion are also attractive for spondylolisthesis with sciatica.

    Degenerative ataxias in children present a rare condition where effective treatments are lacking. Intensive coordinative training based on physiotherapeutic exercises improves degenerative ataxia in adults, but such exercises have drawbacks for children, often including a lack of motivation for high-frequent physiotherapy. Recently developed whole-body controlled video game technology might present a novel treatment strategy for highly interactive and motivational coordinative training for children with degenerative ataxias. We examined the effectiveness of an 8-week coordinative training for 10 children with progressive spinocerebellar ataxia. Training was based on 3 Microsoft Xbox Kinect video games particularly suitable to exercise whole-body coordination and dynamic balance. Training was started with a laboratory-based 2-week training phase and followed by 6 weeks training in children's home environment. Rater-blinded assessments were performed 2 weeks before laboratory-based training, immediately prior to and after the laboratory-based training period, as well as after home training. These assessments allowed for an intraindividual control design, where performance changes with and without training were compared. Ataxia symptoms were significantly reduced (decrease in Scale for the Assessment and Rating of Ataxia score, p = 0.0078) and balance capacities improved (dynamic gait index, p = 0.04) after intervention. Quantitative movement analysis revealed improvements in gait (lateral sway: p = 0.01; step length variability: p = 0.01) and in goal-directed leg placement (p = 0.03). Despite progressive cerebellar degeneration, children are able to improve motor performance by intensive coordination training. Directed training of whole-body controlled video games might present a highly motivational, cost-efficient, and home-based rehabilitation strategy to train dynamic balance and interaction with dynamic environments in a large variety of young-onset neurologic

    The authors report the case of a patient suffering from paraparesis where a venous pathology seemed to be responsible, and the literature is reviewed. A cauda-equina compression by L4/L5 arthrosic pseudo-spondylolisthesis caused troubles of the spinal cord venous drainage, seen at the myelography. There was a neurological deficit above the L4/L5 compression with a psoas and quadriceps deficit. After a L4/L5 laminectomy the neurological signs improved rapidly.

    In this study, we selected final 20 biomarkers for the degenerative aging to develop radiation aging modeling, and validated a few of selected markers to utilize them in the screening of aging modulators. To select the biomarkers of the degenerative aging, 4 categories of aging-related markers (immune/hematopoiesis, oxidative damage, signaling molecule, lipid metabolism) were comparatively analyzed in irradiated and normally aged biosystems (cell lines or mice). In result, most of the biomarkers showed similar changes by irradiation and normal aging. Regarding the immune/hematopoiesis, the decline of immune cell functions (lymphocyte, NK cell) and Th1/Th2 imbalance, and decreased antigen-presenting of dendritic cells were observed and 10 biomarkers were selected in this category. mtDNA deletion was selected for the oxidative damage marker, 6 biomarkers including p21 and p-FOXO3a for signaling molecule biomarkers, and 3 biomarkers including the adipose tissue weight were selected for lipid metabolism. In addition, the various radiation application conditions by single/factionated irradiation and the periods after the irradiation were investigated for the optimal induction of changes of biomarker, which revealed that total 5Gy of 10 or more fractionated irradiations and 4 months or greather period were observed to be optimal. To found the basis for the screening of natural aging modulators, some selected aging biomarkers were validated by their inhibition by well-known natural agents (EGCG, HemoHIM, etc) in aged cell or mouse model. Additionally, by evaluating the reductive efficacy of 5 natural agents on the degeneration of skin and reproductive organs induced by radiation and chemicals (cyclophosphamide, etc), we established the base for the screening of degenerative diseases by various factors

    Thanks to the development of several new researches, the lifetime presented a significant increase, even so, we still have many obstacles to overcome – among them, manage and get responses regarding neurodegenerative diseases. Where we are in the understanding of neuroprotection? Do we really have protective therapies for diseases considered degeneratives such as amyotrophic lateral sclerosis and its variants, Parkinson’s disease, Alzheimer’s disease and many others? Neuroprotection is defined by many researches as interactions and interventions that can slow down or even inhibit the progression of neuronal degeneration process. We make some considerations on this neuroprotective effect. PMID:27127599

    2003-01-01

    The authors review histologic findings from 50 cases of heel spur surgery for chronic plantar fasciitis. Findings include myxoid degeneration with fragmentation and degeneration of the plantar fascia and bone marrow vascular ectasia. Histologic findings are presented to support the thesis that "plantar fasciitis" is a degenerative fasciosis without inflammation, not a fasciitis. These findings suggest that treatment regimens such as serial corticosteroid injections into the plantar fascia should be reevaluated in the absence of inflammation and in light of their potential to induce plantar fascial rupture.

    Background: It has been theorized that degenerative rotator cuff tears most commonly involve the supraspinatus tendon, initiating at the anterior portion of the supraspinatus insertion and propagating posteriorly. The purposes of this study were to determine the most common location of degenerative rotator cuff tears and to examine tear location patterns associated with various tear sizes. Methods: Ultrasonograms of 360 shoulders with either a full-thickness rotator cuff tear (272) or a partial-thickness rotator cuff tear (eighty-eight) were obtained to measure the width and length of the tear and the distance from the biceps tendon to the anterior margin of the tear. Tears were grouped on the basis of their size (anteroposterior width) and extent (partial or full-thickness). Each tear was represented numerically as a column of consecutive numbers representing the tear width and distance posterior to the biceps tendon. All tears were pooled to graphically represent the width and location of the tears within groups. Frequency histograms of the pooled data were generated, and the mode was determined for each histogram representing various tear groups. Results: The mean age (and standard deviation) of the 233 subjects (360 shoulders) was 64.7 ± 10.2 years. The mean width and length of the tears were 16.3 ± 12.1 mm and 17.0 ± 13.0 mm, respectively. The mean distance from the biceps tendon to the anterior tear margin was 7.8 ± 5.7 mm (range, 0 to 26 mm). Histograms of the various tear groups invariably showed the location of 15 to 16 mm posterior to the biceps tendon to be the most commonly torn location within the posterior cuff tendons. The histograms of small tears (a width of infraspinatus. The patterns of tear location across multiple tear sizes suggest that degenerative cuff tears may initiate in a region 13 to 17 mm posterior to the biceps tendon. Clinical Relevance: The findings of this study speak to the specific location of the most common type of rotator

    Purpose: The purpose of the study was to determine the difference in findings between recumbent and upright-sitting MRI of the cervical and lumbosacral spine in patients with related sign and symptoms. Materials and methods: A total of 89 patients were studied (lumbosacral spine: 45 patients; cervical: 44 patients). T1-weighted (TR: 350, TE: 20) fast spin echo and T2-weighted (TR: 2500, TE: 160) fast spin echo images were acquired in the sagittal and axial planes in both the recumbent and sitting-neutral positions. The images were acquired on the Upright{sup TM} MRI unit (Fonar Corporation, Melville, NY). Differences were sought between the recumbent and upright-sitting positions at all levels imaged, in both planes. Results: The total number of cases of pathology was 68, including instances of posterior disc herniation and anterior and posterior spondylolisthesis. Focal posterior disc herniations were noted in 55 patients (cervical: 31, lumbosacral: 24) [62% of patients]. Six of these herniations (cervical: 4, lumbosacral: 2) [11%] were seen only on the upright-sitting study. Focal posterior disc herniations were seen to comparatively enlarge in size in 35 patients on the upright-seated examination (cervical: 21, lumbosacral: 14) [72%], and reduce in size in 9 patients (cervical: 5, lumbosacral: 4) [18%]. Degenerative anterior (n: 11) and posterior (n: 2) spondylolisthesis was seen in 13 patients (cervical: 0, lumbosacral: 13) [15% of patient total]. Anterior spondylolisthesis was only seen on the upright-seated examination in 4 patients (cervical: 0, lumbosacral: 4) [31%]. Anterior spondylolisthesis was comparatively greater in degree on the upright-seated study in 7 patients (cervical: 0, lumbosacral: 7) [54%]. Posterior spondylolisthesis was comparatively greater in degree on the recumbent examination in 2 patients (cervical: 0, lumbosacral: 2) [15%]. The overall combined recumbent miss rate in cases of pathology was 15% (10/68). The overall combined recumbent

    The dynamics of plant community and above- and belowground biomass of the different degenerative stages was researched of Kobresia humlis meadows of Nakchu prefecture in Tibet Autonomous Region. The results indicated that the aggravation of the degree of deterioration of alpine meadow is, the lower the vegetation coverage, percentage of excellent forage, and biodiversity are. The total aboveground biomass is highest in the lightly degraded stages while it is lowest in the extremely degraded stages. With the aggravation of degradation, the aboveground biomass of forbs increases while that of Cyperaceae decreases. We found that the belowground biomass was mostly distributed in the 0-10 cm soil depth in the alpine meadow with a "T"-shape distribution feature, and with the acceleration of deterioration, the numbers of roots becomes less and less. Meanwhile, the above- and belowground biomass of the different degraded communities was significantly correlated(r=0.963). There is an obvious positive correlation with the above- and belowground biomass in different degenerative stages, and their ratio increased with the aggravation of degradation.

    Full Text Available Degenerative suspensory ligament desmitis (DSLD is a chronic, debilitating disease occurring primarily in Peruvian Pasos and Peruvian Paso crosses. However, many other breeds are afflicted as well. DSLD is characterized by a slowly progressing bilateral or quadrilateral lameness. Typically, the owner does not recall any trauma or performance related injury. Fetlock effusion, static and dynamic hyperextension and degenerative joint disease are hallmarks on physical examination. Ultrasonography of affected ligaments reveals diffuse loss of echogenicity, and an irregular fiber pattern. Though until recently DSLD was considered a collagen disorder strictly limited to suspensory ligaments (SLs, our data show that it is a systemic disease involving tissues with high content of collagen. We have identified abnormal accumulations of proteoglycans not only in the SLs, but also in the superficial and deep digital flexor tendons, patellar and nuchal ligaments, aorta, coronary arteries and sclerae of DSLD-affected horses. Our most recent data point to the presence of an abnormal form of decorin in these proteoglycan deposits. This decorin also exhibited altered biological activity. Treatment for DSLD-affected horses is empirical and directed at minimizing musculoskeletal pain and providing support for the suspensory apparatus. Restricted exercise, supportive bandages and nonsteroidal anti-inflammatory drugs provide some, but usually only temporary relief. Unfortunately, unrelenting pain, severe lameness and suffering require all too often humane euthanasia.

    At the Radiologic Department of the Staedt. Krankenhaus Passau, 473 patients with degenerative diseases in the big joints and the spine were irradiated with the caesium unit between 1971 and 1979. Among these patients, 249 could be followed up during a prolonged period (1/2 to 9 years, i.e. 4.2 years on an average). According to the categories of v. Pannewitz, 11% were pain-free at this moment, 21% showed an essential improvement, 29% showed an improvement, and 39% were not influenced by the treatment. 13.5% showed recurrent pains; these were mentioned as 'not influenced' in the statistical analysis. It is proved that the relief of pain does not depend on the age of the patients, but on the anamnesis period, the results of the X-ray examiantion, and the degree of the restriction of mobility. Due to the delay of irradiation, a preliminary treatment mostly produces a less favorable radiotherapeutic result. Compared with other therapeutic methods, the long term results of radiotherapy of degenerative joint diseases are generally favorable. This conclusion is also confirmed by the results of patients checked up more than five years after the treatment.

    Full Text Available Posterior lumbar interbody fusion using cages, titanium rods, and pedicle screws is considered today as the gold standard of surgical treatment of lumbar degenerative disease and has produced satisfying long-term fusion rates. However this rigid material could change the physiological distribution of load at the instrumental and adjacent segments, a main cause of implant failure and adjacent segment disease, responsible for a high rate of further surgery in the following years. More recently, semirigid instrumentation systems using rods made of polyetheretherketone (PEEK have been introduced. This clinical study of 21 patients focuses on the clinical and radiological outcomes of patients with lumbar degenerative disease treated with Initial VEOS PEEK®-Optima system (Innov’Spine, France composed of rods made from PEEK-OPTIMA® polymer (Invibio Biomaterial Solutions, UK without arthrodesis. With an average follow-up of 2 years and half, the chances of reoperation were significantly reduced (4.8%, quality of life was improved (ODI = 16%, and the adjacent disc was preserved in more than 70% of cases. Based on these results, combined with the biomechanical and clinical data already published, PEEK rods systems can be considered as a safe and effective alternative solution to rigid ones.

    Objective To investigate the complications following long-segment versus short-segment fixation and fusion for degenerative scoliosis ( DS ). Methods From January 2007 to February 2012, 94 patients with DS underwent posterior spinal fusion, whose clinical and imaging data were retrospectively reviewed. Long-segment ifxation was performed on 66 patients ( 70.2%). There were 11 males and 55 females, whose mean age was ( 59.1±9.9 ) years old and mean preoperative Cobb’s angle was ( 39.3±9.1 ) °. Short-segment ifxation was performed on 28 patients ( 29.8%). There were 5 males and 23 females, whose mean age was ( 62.7±12.3 ) years old and mean preoperative Cobb’s angle was ( 18.5±6.4 ) °. Hospital records were reviewed for the patients’ age, gender, number of decompression and fusion levels, intraoperative blood loss, operation time, postoperative hospital stay, coronal Cobb’s angle, coronal and sagittal balance, early perioperative complications (<3 months after the surgery ) and late complications (≥3 months after the surgery ). Results No statistically signiifcant differences existed between the 2 groups in the age ( P=0.081 ), gender ( P=0.412 ) and number of decompression levels ( P=0.067 ). The average numbers of fusion levels were 11.1±5.5 in the long-segment fusion group and 3.8±3.2 in the short-segment fusion group. The mean postoperative Cobb’s angles were ( 13.3±6.5 ) ° and ( 8.8±6.7 )° respectively in each group. The mean operation time and postoperative hospital stay were ( 260.8±35.6 ) min and ( 6.7±5.5 ) days in the long-segment fusion group, which were obviously longer than ( 188.3±20.7 ) min and ( 4.9±3.8 ) days in the short-segment fusion group. There were statistically signiifcant differences between the 2 groups ( P<0.01 ). The mean blood loss was ( 2788.0± 63.8 ) ml in the long-segment fusion group, which was obviously greater than ( 1642.0±49.9 ) ml in the short-segment fusion group. There were statistically

    Full Text Available BACKGROUND Posterior Lumbar Interbody Fusion (PLIF and Transforaminal Lumbar Interbody Fusion (TLIF create intervertebral fusion by means of a posterior approach. Successful results have been reported with allograft, various cages (for interbody support, autograft and recombinant human bone morphogenetic protein‐2. Interbody fusion techniques facilitate reduction and enhance fusion. Corticocancellous laminectomy bone chips alone can be used as a means of spinal fusion in patients with single level instrumented PLIF. This has got a good fusion rate. PLIF with cage gives better fusion on radiology than PLIF with iliac bone graft, but no statistical difference in the clinical outcome. Cage use precludes complications associated with iliac bone harvesting. The reported adjacent segment degeneration was 40.5% and reoperation was 8.1% after 10 years of follow up. MATERIALS AND METHODS 30 cases of spondylolisthesis who attended the Orthopaedic Outpatient Department of Andhra Medical College, Visakhapatnam, from 2014 to 2016 were taken up for study. All the cases were examined clinically and confirmed radiologically. The patient’s age, sex, symptoms and duration were noted and were examined clinically for the status of the spine. Straight leg raising test was done and neurological examination of the lower limbs performed. All the patients were subjected to the radiological examination of the lumbosacral spine by taking anteroposterior, lateral (flexion and extension views, oblique views to demonstrate spondylolysis and spondylolisthesis. MRI and x-rays studies were done in all the cases to facilitate evaluation of the root compression disk changes and spinal cord changes. RESULTS In our study, we followed all the 30 patients after the surgery following procedure of removal of loose lamina, spinous process and fibrocartilaginous mass, PLIF with only the laminectomy bone mass and CD screw system fixation up to 2 years. 12 patients (40% had excellent

    Degenerative scoliosis is one of the main causes of low back pain and cosmetic deformity among the elderly. And it is more prevalent nowadays. Although the etiology is unclear, it is thought to be associated with osteoporosis, asymmetric degeneration, abnormal expression of gene, age, gender, etc. Better understanding the pathogenesis will be useful in the management of degenerative scoliosis.

    In most biological systems, second messengers and their key regulatory and effector proteins form links between multiple cellular signaling pathways. Such signaling nodes can integrate the deleterious effects of genetic aberrations, environmental stressors, or both in complex diseases, leading to cell death by various mechanisms. Here we present a systems (network) pharmacology approach that, together with transcriptomics analyses, was used to identify different G protein–coupled receptors that experimentally protected against cellular stress and death caused by linked signaling mechanisms. We describe the application of this concept to degenerative and diabetic retinopathies in appropriate mouse models as an example. Systems pharmacology also provides an attractive framework for devising strategies to combat complex diseases by using (repurposing) US Food and Drug Administration–approved pharmacological agents.

    The central zone of the triangular fibrocartilage complex (TFCC) of the wrist is thought to be avascular and is generally considered to lack any healing potential. The purpose of this study was to investigate, if cartilage cells of degenerative disc lesions possess any healing or proliferation potential and whether ulna length plays a significant role in the proliferation process. Cells positive for proliferating cell nuclear antigen (PCNA) were found in all specimens. Specimens of patients with ulna positive variance showed a decreased number of PCNA positive cells than specimens of patients with either negative or neutral ulna variance. We found that cartilage cells of Palmer type 2C lesions undergo mitotic cell division, thus exhibiting proliferation capability. It could not be shown that ulnar length is significantly correlated with the number of PCNA positive cells.

    A number of pathologic changes have been reported in spinal surgery specimens. The frequency of many of these is not well defined. We retrospectively reviewed the histologic features of 985 extradural spinal surgery specimens. Of the cases, 1.6% were identified clinically as synovial cysts. In addition, synovial tissue was seen in another 5.3% of cases, often embedded within disk material. Neovascularization of disk tissue was present in 8.1% of cases, chondrocyte clusters in 18.3%, and calcium pyrophosphate crystals in 2.8%, predominantly within disk material. With the exception of crystal deposits, all of these changes were significantly more common in the lumbar spine. A better understanding of cell-based degenerative changes will become essential with increasing research into cell-based therapies for spinal disk disease. We report data on the frequency of different pathologic changes and describe synovial metaplasia as a reactive change not previously reported.

    2011-03-01

    The function of vitamin K is to serve as a co-factor during the post-translational carboxylation of glutamate (Glu) residues into γ-carboxyglutamate (Gla) residues. The vital importance of the Gla-proteins essential for normal haemostasis is well recognized. During recent years, new Gla-containing proteins have been discovered and the vitamin K-dependent carboxylation is also essential for their function. It seems, however, that our dietary vitamin K intake is too low to support the carboxylation of at least some of these Gla-proteins. According to the triage theory, long-term vitamin K inadequacy is an independent, but modifiable risk factor for the development of degenerative diseases of ageing including osteoporosis and atherosclerosis.

    The high energy (1-4MeV) focused ion beam (nuclear microbeam) has found uses in many scientific disciplines through a wide variety of ion beam based techniques. Of the many techniques available, the powerful combination of Particle Induced X-Ray Emission (PIXE), Rutherford Backscattering Spectrometry (RBS), and Scanning Transmission Ion Microscopy (STIM) is proving to be extremely useful, particularly in the characterisation and elemental analysis of thin specimens. In this paper we briefly review these ion beam techniques, as well as the hardware required for their application. Finally, we describe the application of the PIXE, RBS and STIM techniques in conjunction with a scanning focused 2MeV proton microbeam (nuclear microscopy). The examples chosen to illustrate the potential of nuclear microscopy are recent investigations into the degenerative diseases atherosclerosis (coronary heart disease), Parkinson`s disease and Alzheimer`s disease.

    Full Text Available Based on the survey of 148 patients with an lumbar degenerative disease, there have been studied immediate and medium-term results of the comprehensive conservative treatment of the patients with and without application of traction exposure on the spine. It was found out that the traction of the spine leads to a quicker and more durable relief of symptoms in comparison with the control groups where traction therapy wasn't carried out. Application of the traction-extended therapy in three planes with a usage of robotized set for dry skeletal traction of a new generation KinetracKNX-7000 is proved to increase the effectiveness of treatment for the patients with stated pathology, fasten regress of the pain syndrome and clinical symptomatology, lead to more durable and lasting remission of the desease, in comparison with the patients that had traction of the spine in one plane only during the treatment.

    2015-12-01

    The complement system is a key innate immune defence against infection and an important driver of inflammation; however, these very properties can also cause harm. Inappropriate or uncontrolled activation of complement can cause local and/or systemic inflammation, tissue damage and disease. Complement provides numerous options for drug development as it is a proteolytic cascade that involves nine specific proteases, unique multimolecular activation and lytic complexes, an arsenal of natural inhibitors, and numerous receptors that bind to activation fragments. Drug design is facilitated by the increasingly detailed structural understanding of the molecules involved in the complement system. Only two anti-complement drugs are currently on the market, but many more are being developed for diseases that include infectious, inflammatory, degenerative, traumatic and neoplastic disorders. In this Review, we describe the history, current landscape and future directions for anti-complement therapies.

    Full Text Available Osteoporosis has become a major medical problem as the aged population of the world rapidly grows. Osteoporosispredisposes patients to fracture, progressive spinal deformities, and stenosis, and is subject to be a major concernbefore performing spine surgery, especially with bone fusions and instrumentation. Osteoporosis has often beenconsidered a contraindication for spinal surgery, while in some instances patients have undergone limited and inadequateprocedures in order to avoid concomitant instrumentation. As the population ages and the expectations of older patientsincrease, the demand for surgical treatment in older patients with osteoporosis and spinal degenerative diseasesbecomes progressively more important. Nowadays, advances in surgical and anesthetic technology make it possible tooperate successfully on elderly patients who no longer accept disabling physical conditions. This article discusses thebiomechanics of the osteoporotic spine, the diagnosis and management of osteoporotic patients with spinal conditions,as well as the novel treatments, recommendations, surgical indications, strategies and instrumentation in patients withosteoporosis who need spine operations.

    Stem cell-derived retinal pigment epithelium (RPE) and photoreceptors (PRs) have restored vision in preclinical models of human retinal degenerative disease. This review discusses characteristics of stem cell therapy in the eye and the challenges to clinical implementation that are being confronted today. Based on encouraging results from Phase I/II trials, the first Phase II clinical trials of stem cell-derived RPE transplantation are underway. PR transplant experiments have demonstrated restoration of visual function in preclinical models of retinitis pigmentosa and macular degeneration, but also indicate that no single approach is likely to succeed in overcoming PR loss in all cases. A greater understanding of the mechanisms controlling synapse formation as well as the immunoreactivity of transplanted retinal cells is urgently needed.

    This study prospectively examined the relationship of direct and indirect measures of shoulder activity with the risks of tear progression and pain development in subjects with an asymptomatic degenerative rotator cuff tear. A cohort of asymptomatic degenerative rotator cuff tears was prospectively monitored annually, documenting tear size progression with ultrasound imaging and potential shoulder pain development. Shoulder activity level, self-reported occupational and physical demand level, and hand dominance were compared with risks of tear enlargement and future pain development. The study monitored 346 individuals with a mean age of 62.1 years for a median duration of 4.1 years (interquartile range [IQR], 2.4-7.9 years). Tear enlargement was seen in 177 shoulders (51.2%), and pain developed in 161 shoulders (46.5%) over time. Tear presence in the dominant shoulder was associated with a greater risk of tear enlargement (hazard ratio, 1.40; P = .03) and pain development (hazard ratio, 1.63; P = .002). Shoulder activity level (P = .37) and occupational demand level (P = .62) were not predictive of tear enlargement. Occupational demand categories of manual labor (P = .047) and "in between" (P = .045) had greater risks of pain development than sedentary demands. The median shoulder activity score for shoulders that became painful was lower than for shoulders that remained asymptomatic (10.0 [IQR, 7.0-13.0] vs. 11.0 [IQR, 8.0-14.0], P = .02). Tear enlargement and pain development in asymptomatic tears are more common with involvement of the dominant shoulder. Shoulder activity level is not related to tear progression risks. Pain development is associated with a lower shoulder activity level even though patients with higher occupational demands are more likely to develop pain.

    Study Design Retrospective population-based observational study. Objective To assess the growth of cervical spine surgery performed in an outpatient setting. Methods A retrospective study was conducted using the United States Healthcare Cost and Utilization Project's State Inpatient and Ambulatory Surgery Databases for California, New York, Florida, and Maryland from 2005 to 2009. Current Procedural Terminology, fourth revision (CPT-4) and International Classification of Diseases, ninth revision Clinical Modification (ICD-9-CM) codes were used to identify operations for degenerative cervical spine diseases in adults (age > 20 years). Disposition and complication rates were examined. Results There was an increase in cervical spine surgeries performed in an ambulatory setting during the study period. Anterior cervical diskectomy and fusion accounted for 68% of outpatient procedures; posterior decompression made up 21%. Younger patients predominantly underwent anterior fusion procedures, and patients in the eighth and ninth decades of life had more posterior decompressions. Charlson comorbidity index and complication rates were substantially lower for ambulatory cases when compared with inpatients. The majority (>99%) of patients were discharged home following ambulatory surgery. Conclusions Recently, the number of cervical spine surgeries has increased in general, and more of these procedures are being performed in an ambulatory setting. The majority (>99%) of patients are discharged home but the nature of analyzing administrative data limits accurate assessment of postoperative complications and thus patient safety. This increase in outpatient cervical spine surgery necessitates further discussion of its safety.

    Objective. Signal intensity changes in lumbar pedicles, similar to those described in vertebral body endplates adjacent to degenerated discs, have been described as an ancillary sign of spondylolysis on MRI. The purpose of this study was to determine whether pedicle marrow signal intensity changes also occur in association with facet degenerative joint disease.Design. Eighty-nine lumbar spine MRI examinations without spondylolysis were reviewed for marrow signal intensity changes in pedicles and vertebral bodies as well as for facet degenerative joint disease.Results. Five percent (46/890) of lumbar pedicles in 23 patients had marrow signal intensity changes. Ninety-one percent (42/46) of the abnormal pedicles had adjacent degenerative joint disease of the facets, while only 21% (189/890) of normal pedicles had adjacent facet degenerative joint disease (p<0.001). Eighty-nine percent (41/46) of the pedicles with marrow signal intensity changes had adjacent degenerative disc disease.Conclusions. Pedicle marrow signal intensity changes are not a specific sign of spondylolysis; they are commonly seen with adjacent facet degenerative joint disease in the absence of spondylolysis. Pedicle marrow signal intensity changes are probably a response to abnormal stresses related to abnormal motion or loading caused by the degenerative changes in the spinal segment. (orig.)

    2005-01-01

    Objective: To evaluate the results of total knee arthroplasty (TKA) in patients with posttraumatic degenerative arthritis due to a previous fracture around the knee. Methods: We analyzed the results of 15 TKAs, performed from 1997 to 2003, in 15 patients with post-traumatic degenerative arthritis due to a previous fracture around knee. There were 3 women and 12 men with an average age of 58 years (range, 31-76 years). The time from fracture to arthroplasty averaged 8.2 years (range, 2-27 years). Internal fixation had previously been performed in 8 patients resulting in retained hardware. At the time of arthroplasty a femoral fracture malunion was present in two knees. Lateral retinacular release (4 knees), extensor mechanism realignment (1 knee) or medial collateral ligament reconstruction (1 knee) were needed at the time of arthroplasty. Results: Follow-up averaged 35 months (range, 12-73 months). No patient was lost for follow-up. According to the Knee Society Score scale, the mean preoperative knee score was 37 (range, 10-70) and functional score was 41 (range, 0-60). They were improved significantly to a mean of 84 (range, 10-100) and 76 (range, 20-100) points, respectively at the latest follow-up. The mean knee arc of motion were improved from 84° preoperation to 94° at the latest follow-up. Postoperative manipulation under anesthesia for poor motion was carried out in 4 knees. No knee had aseptic loosening that required subsequent revision. Two knees developed superficial infection and were treated with debridement. It subsequently recovered with the retention of components. Conclusions: Significant improvement in function and relief of pain has been achieved in patients with previous fractures undergoing subsequent TKA. However, this procedure is technically demanding and patients are at increased risk for restricted motion and need more care following TKA. This study suggests that the outcome of TKA may be improved further by making special efforts to

    Objective To assess the feasibility of the selective transmuscular paraspinal approach ( TPA )for partial lumbar degenerative disease and to compare it with the traditional approach. Methods Fifty patients were divided randomly into two groups. Patients in control group received surgical treatment of spinal posterior approach, and those in experimental group received TPA surgery. Lumbar spinal canal decompression was performed in both groups; pedicle screw rod system was implemented for those who needed internal fixation, reduction for spondylolisthesis or scoliosis, and interbody fusion for lumbar spinal instability. The intraoperative blood loss, visual analogue scale( VAS ) score and Oswestry disability index ( ODI )in the two groups were analyzed. Results Patients included in this study were all followed up for more than 1 year. Surgical treatment significantly relieved the low back pain in patients; Spondylolisthesis and scoliosis were well reduced; Fusion occurred 1 year after surgery in alls patients undergoing interbody fusion. The intraoperative blood loss, VAS and ODI after surgery of TPA group were significantly better than those of the control group. Conclusion Compared with the traditional approach, TPA is a better therapy choice for certain partial lumbar degenerative disease. It can not only facilitate the surgical treatment, such as decompression, reduction, fixation and inter body fusion, but also restore the original structure of spines and reduce iatrogenic trauma more effectively.%目的 评价椎旁肌间隙入路选择性治疗部分腰椎退行性病变的可行性,并与传统后正中入路相比较.方法 50例患者随机分为两组,一组采用脊柱后正中入路(后正中入路组),另一组采用椎旁肌间隙入路(肌间隙入路组).均行腰椎管减压;对需要行内固定者置入椎弓根钉棒系统,对有腰椎滑脱或侧凸者进行复位,对腰椎不稳定者行椎间植骨融合.对两组病例的术中出血量、

    Degenerative disc disease (DDD) develops in the spine as vertebral discs degenerate and osseous excrescences or outgrowths naturally form to restabilize unstable segments of the spine. These osseous excrescences, or osteophytes, may progress or stabilize in size as the spine reaches a new equilibrium point. We have previously created a CAD system that detects DDD. This paper presents a new system to determine the severity of DDD of individual vertebral levels. This will be useful to monitor the progress of developing DDD, as rapid growth may indicate that there is a greater stabilization problem that should be addressed. The existing DDD CAD system extracts the spine from CT images and segments the cortical shell of individual levels with a dual-surface model. The cortical shell is unwrapped, and is analyzed to detect the hyperdense regions of DDD. Three radiologists scored the severity of DDD of each disc space of 46 CT scans. Radiologists' scores and features generated from CAD detections were used to train a random forest classifier. The classifier then assessed the severity of DDD at each vertebral disc level. The agreement between the computer severity score and the average radiologist's score had a quadratic weighted Cohen's kappa of 0.64.

    Radon, a naturally occurring radioactive gas, has variable distribution in the environment as a decay product of uranium occurring in a wide range of rocks, soils and building materials. Although radon dissipates rapidly in outdoor air, it concentrates in the built environment, and inhalation of {sup 222}Rn and its progeny {sup 218}Po and {sup 214}Po is believed to provide the majority of the radioactive dose to the respiratory system. While the connection between radon and lung cancer has long been recognised and investigated, recent studies have highlighted potential links between radon and other conditions, among them Multiple Sclerosis, Alzheimer and Parkinson Diseases, and Paget Disease of Bone. A strong case exists for clarifying the relationship between radon and these other conditions, not least since radon remediation to reduce lung cancer may conceivably have additional benefits hitherto unrecognized. The present status of the postulated links between environmental radon gas and degenerative conditions is reviewed, and recommendations for further research into levering current anti-radon campaigns are made.

    Spongiform degeneration is characterized by vacuolation in nervous tissue accompanied by neuronal death and gliosis. Although spongiform degeneration is a hallmark of prion diseases, this pathology is also present in the brains of patients suffering from Alzheimer's disease, diffuse Lewy body disease, human immunodeficiency virus (HIV) infection, and Canavan's spongiform leukodystrophy. The shared outcome of spongiform degeneration in these diverse diseases suggests that common cellular mechanisms must underlie the processes of spongiform change and neurodegeneration in the central nervous system. Immunohistochemical analysis of brain tissues reveals increased ubiquitin immunoreactivity in and around areas of spongiform change, suggesting the involvement of ubiquitin-proteasome system dysfunction in the pathogenesis of spongiform neurodegeneration. The link between aberrant ubiquitination and spongiform neurodegeneration has been strengthened by the discovery that a null mutation in the E3 ubiquitin-protein ligase mahogunin ring finger-1 (Mgrn1) causes an autosomal recessively inherited form of spongiform neurodegeneration in animals. Recent studies have begun to suggest that abnormal ubiquitination may alter intracellular signaling and cell functions via proteasome-dependent and proteasome-independent mechanisms, leading to spongiform degeneration and neuronal cell death. Further elucidation of the pathogenic pathways involved in spongiform neurodegeneration should facilitate the development of novel rational therapies for treating prion diseases, HIV infection, and other spongiform degenerative disorders.

    As Magnetic Resonance (MR) imaging and Ultrasound (US) allow the evaluation of soft-tissue structures not previously possible with other imaging techniques, a clinical study has been undertaken to determine the value of these 2 modalities in the detection of lesions in the Achilles tendon (AT), other than acute total rupture. Seven healthy subjects and 28 symptomatic patients with Achillodynia and/or signs of thickening of the AT were investigated with MR and US; all results were compared with the clinical features. Surgical findings were available in 14 patients. Patients were divided into 3 groups; those with tendon thickening, incomplete and complete ruptures. Thickening of the AT was easily detected with both methods. MR was superior in the detection of incomplete tendon rupture and in the evaluation of various stages of chronic degenerative changes. It is concluded that only if US remains unclear, an additional MR study should be performed and together with the clinical diagnosis indication for surgery can be made more efficient.

    2012-01-01

    The aim of this review was to present an over view of degenerative rotator cuff tears and a suggested management protocol based upon current evidence. Degenerative rotator cuff tears are common and are a major cause of pain and shoulder dysfunction. The management of these tears is controversial, as to whether they should be managed non-operatively or operatively. In addition when operative intervention is undertaken, there is question as to what technique of repair should be used. This review describes the epidemiology and natural history of degenerative rotator cuff tears. The management options, and the evidence to support these, are reviewed. We also present our preferred management protocol and method, if applicable, for surgical fixation of degenerative rotator cuff tears. PMID:23241147

    Purpose. To investigate the evidence of minimally invasive (MI) versus open (OP) posterior lumbar fusion in treatment of lumbar spondylolisthesis from current prospective literatures. Methods. The electronic literature database of Pubmed, Embase, and Cochrane library was searched at April 2016. The data of operative time, estimated blood loss and length of hospital stay, visual analog scale (VAS) of both lower back pain and leg pain, Oswestry disability index (ODI), SF-36 PCS (physical component scores) and SF-36 MCS (mental component scores), complications, fusion rate, and secondary surgery were extracted and analyzed by STATA 12.0 software. Results. Five nonrandom prospective comparative studies were included in this meta-analysis. The meta-analysis showed that the MI group had a significantly longer operative time than OP group, less blood loss, and shorter hospital stay. No significant difference was found in back pain, leg pain, ODI, SF-36 PCS, SF-36 MCS, complications, fusion rate, and secondary surgery between MI and OP groups. Conclusion. The prospective evidence suggested that MI posterior fusion for spondylolisthesis had less EBL and hospital stay than OP fusion; however it took more operative time. Both MI and OP fusion had similar results in pain and functional outcomes, complication, fusion rate, and secondary surgery. PMID:28154826

    Isthmic spondylolisthesis due to pars defects resulting from trauma or spondylolysis is not uncommon. Symptomatic patients with such pars defects are traditionally treated with a variety of fusion surgeries. The authors present a unique case in which such a patient was successfully treated with endoscopic discectomy without iatrogenic destabilization. A 31-year-old man presented with a history of left radicular leg pain along the distribution of the sciatic nerve. He had a disc herniation at L5/S1 and bilateral pars defects with a Grade I spondylolisthesis. Dynamic radiographic studies did not show significant movement of L-5 over S-1. The patient did not desire to have a fusion. After induction of local anesthesia, the patient underwent an awake transforaminal endoscopic discectomy via the extraforaminal approach, with decompression of the L-5 and S-1 nerve roots. His preoperative pain resolved immediately, and he was discharged home the same day. His preoperative Oswestry Disability Index score was 74, and postoperatively it was noted to be 8. At 2-year follow-up he continued to be symptom free, and no radiographic progression of the listhesis was noted. In this case preservation of stabilizing structures, including the supraspinous and interspinous ligaments and the facet capsule, may have reduced the likelihood of iatrogenic instability while at the same time achieving symptom control. This may be a reasonable option for select patient symptoms confined to lumbosacral radiculopathy.

  1. Frying process in the relation fat/degenerative diseases.

    Directory of Open Access Journals (Sweden)

    Varela, G.

    1998-08-01

    Full Text Available Among the various components of the diet, fat receives very dose attention because of its relationship to several chronic degenerative diseases (CDD. Currently most of the available information on these relationships is derived from epidemiologic or experimental studies in which lipid intake is calculated using food composition tables. In most of these tables the quoted lipid content is that of raw food, whereas most foods are usually consumed only after being subjected to several culinary processes. Often there is no indication of the type of fat used in food processing in general or in frying in particular. But as it known, in the course of these processes the lipid content undergoes important qualitative and quantitative changes and not keeping them in mind may be the underlying cause of the difficulties an the confounding results in studies trying to establish the relationship between lipid intake an health. In the Mediterranean diet, about 50% of total dietary fat is derived not from the food itself but from the cooking fat, of which only a small fraction is eaten raw (as dressings and the greatest proportion is used in thermal culinary processes, mainly deep-frying. The scientific study of the process whereby fat penetrates into fried foods has shown the benefits of this cooking method. If the process is correctly carried out, the amount of fat ingested with fried foodstuffs is not greater than when other procedures involving fat are used (for example, sautening, stewing or canning in oil. Very schematically deep-frying is a technique that replaces a fraction of the water content of food by cooking fat. Consecuently, the fat composition of the fried lean foods will be the same as that cooking fat. The process is more complex with fatty foods, and there are not great changes in the total quantity of fat in the fried food before and after frying. However, there are notable quality changes and these depend on the concentration gradients

    Traumatic and degenerative disc lesions cause ulnar-sided wrist pain. To date, anatomical investigations of cadaver triangular fibrocartilage discs examining the innervation of the triangular fibrocartilage complex have found no evidence of nerve fibers in the healthy disc. In this study, we immunohistologically investigated biopsies from patients with either central traumatic or degenerative disc lesions, to determine the existence of nerve fibers. We hypothesized that an ingrowth of nerve fibers causes ulnar-sided wrist pain associated with traumatic and degenerative disc lesions. We included 32 patients with a traumatic Palmer 1A lesion and 17 patients with a degenerative Palmer 2C lesion in the study. We obtained a biopsy of each patient and stained the specimen with protein gene product 9.5 for nerve fiber detection. There were no nerve fibers in either traumatic or degenerative disc lesions. In addition, the marginal areas of the biopsies showed no evidence of nerve fibers. Traumatic and degenerative disc lesions show no ingrowth of nerve fibers.

    The purpose of this study was to clarify the relevance of degenerative changes in the sacroiliac joint (SIJ) and the joints in the lower limb and lumbar spine using age estimation methods. We also examined the shape of the auricular surface to determine the effect of degenerative changes on each joint. A total of 200 iliac auricular surfaces from 100 Japanese male skeletons were examined macroscopically in accordance with conventional methods of age estimation. From the obtained estimated age, we calculated the deflection values, which represented the degree of degenerative changes of the joints. For comparison, we used osteophyte score data of the hip, knee, and zygapophyseal joints in lumbar spines from previous studies which had used the same bone specimens. As a quantitative indicator of auricular surface morphology, we defined the constriction ratio (CR) of the auricular surface and compared the CR values obtained with various measured values. Degenerative changes in the SIJ were positively correlated with those in both the hip joint and zygapophyseal joint, but a correlation with knee joints was found only on the left side. In skeletons from individuals aged ≥60 years as time of death, the CR was significantly different between the group with high scores and those with low scores in both the hip and sacroiliac joints. It has been suggested that degenerative changes in SIJs interact with those in the hip joint and zygapophyseal joint. In addition, the shape of the auricular surface may also be a relevant factor for degenerative changes in these joints.

    Long-standing scaphoid nonunion, scaphoid malunion, and chronic scapholunate dissociation result in malalignment of the carpal bones, progressive carpal collapse, instability, and osteoarthritis of the wrist. The most commonly used procedures to treat scaphoid nonunion advanced collapse (SNAC) and scapholunate advanced collapse (SLAC) wrists are the four-corner fusion (4CF) and the proximal row carpectomy (PRC). The purpose of this study was to evaluate the clinical outcome of a different treatment modality: radial styloidectomy and scaphocapitolunate (SCL) arthrodesis. This treatment option is chosen in an effort to maintain the joint contact surface and load transmission across the radiocarpal joint. We conducted a retrospective review of 20 patients (average age 62 years, range: 27 to 75 years) treated from 1994 to 2010. Seven patients were treated for SNAC, 12 patients for SLAC wrists, and 1 for degenerative joint disease following a transscapho-transcapitate perilunar dislocation. Sixteen patients had Herbert screw fixation, and four had Spider plate fixation. All patients had autologous bone graft used for the arthrodesis. The mean follow-up was 4.6 years (range: 2 to 9.6 years). Patients were evaluated clinically and radiographically. Nineteen of 20 arthrodeses healed on an average of 9.6 weeks. One patient was reoperated 8 months after the initial operation with salvage of the SCL arthrodesis with a spider plate with an adequate result. The mean active flexion-extension arc was 70 degrees and the radioulnar deviation arc was 23 degrees. Pain decreased in all patients, 13 of whom were pain free postoperatively. The average postoperative disabilities of arm, shoulder, and hand score was 24. Radiographically, neither radiolunate nor radioscaphoid arthritis was noted on follow-up. SCL arthrodesis with radial styloidectomy resulted in an adequate residual range of motion and pain relief. This method preserves the normal ulnar sided joints of the carpus and

    This study was designed to determine the association between LSE, spondylolisthesis, facet arthropathy, lumbar canal stenosis, BMI, radiculopathy and bone marrow edema at conventional lumbar spine MR imaging. This is a retrospective radiological study; 441 consecutive patients with low back pain (224 men and 217 women; mean age 57.3 years; mean BMI 26) underwent conventional lumbar MRI using a 1.5-T magnet (Avanto, Siemens). Lumbar MR images were reviewed by consensus for the presence of LSE, spondylolisthesis, facet arthropathy, lumbar canal stenosis, radiculopathy and bone marrow edema. Descriptive statistics and association studies were conducted using STATA software 11.0. Association studies have been performed using linear univariate regression analysis and multivariate regression analysis, considering LSE as response variable. The overall prevalence of LSE was 40%; spondylolisthesis (p = 0.01), facet arthropathy (p back pain. Longitudinal simultaneous X-ray/MRI studies should be conducted to test the relationship of LSE with lumbar spinal instability and low back pain.

    The purpose of this mixed prospective and retrospective case series was to evaluate the long-term health-related quality of life and physical disability after in situ arthrodesis for high-grade isthmic spondylolisthesis. Thirty-five of forty consecutive patients who had in situ spinal arthrodesis for high-grade isthmic spondylolisthesis at a mean age of fifteen years (range, nine to twenty-five years) completed validated questionnaires (Short Form-36 [SF-36], EuroQol-5 Dimensions [EQ-5D], Zung depression scale, Oswestry disability index [ODI], Million score, and back and leg pain visual analog scale [VAS]) and underwent physical examination twenty-nine years (range, twenty-three to thirty-five years) after surgery. The mean age at the time of follow-up was forty-three years (range, thirty-seven to fifty-one years). In the absence of a formal control group, the scores on the SF-36 and EQ-5D were compared with Swedish normative data. The proportion of patients at work was compared with an age-matched control group derived from official statistics of Sweden. The Million score at the long-term follow-up was compared with the corresponding results at the mid-term follow-up of the same patients at a mean age of twenty-two years. The scores on the SF-36 and EQ-5D were similar to the scores of the general Swedish population. The mean Zung depression scale score was 30 (range, 20 to 52), the mean ODI score was 10 (range, 0 to 34), the mean back pain VAS score was 13 (range, 0 to 72), and the mean leg pain VAS score was 9 (range, 0 to 60). The Million score averaged 28 (range, 0 to 109) and was slightly worsened compared with the score of 19 (range, 0 to 94) at the mid-term follow-up (p = 0.034). The proportion of patients at work was the same as that for the age-matched general Swedish population. Our study shows good outcomes in health-related quality of life, disability, pain, and ability to work at up to twenty-nine years after in situ lumbar spine arthrodesis for high

    The ageing process is influenced by a variety of factors, including extrinsic, malleable lifestyle variables. The present paper deals with the epidemiological evidence for the role of dietary patterns and key nutritional concerns in relation to survival and ageing-related disorders that present themselves in later life. Healthful dietary patterns appear to be most relevant in old age. Specific nutritional concerns are related to vitamin D, vitamin B12 and protein malnutrition. An important challenge to further expand the knowledge base is currently addressed by the NuAge project, acknowledging the complexity of the ageing process and integrating different dimensions of research into human healthy ageing. In the meantime, reversing poor adherence to existing guidelines for a healthy diet remains a first challenge in public health nutritional practices.

    Objective To investigate the safety and clinical effects of surgical treatment of degenerative lumbar spine diseases in elderly patients. Methods 42 patients with degenerative lumbar spine diseases who were enrolled from January 2008 to December 2011 selectively underwent surgical treatment, including 6 patients with lumbar disc herniation, 10 patients with lumbar disc herniation and spinal stenosis, 6 patients with degenerative lumbar spondylolisthesis and 20 patients with spinal stenosis. There were 28 males and 14 females, with an average age of 77.2 years old ( range;75-84 years ). They were followed up for a mean period of 31 months ( range;17-64 months ). The preoperative concomitant diseases, postoperative complications and relevant treatment methods were analyzed. The clinical effects were evaluated by the Oswestry Disability Index ( ODI ) and the Visual Analogue Scale ( VAS ). Based on the anteroposterior ( AP ), lateral and dynamic X-ray iflms of the lumbar spine during the follow-up, the lumbar spinal stability, lumbar spinal fusion and implants were observed after the surgery. Results The postoperative complications included 7 cases of increased blood pressure, 1 case of angina, 1 case of cerebral infarction, 4 cases of pulmonary infection and 3 cases of cerebrospinal lfuid leakage. Operational segment instability or internal ifxation failure was not found based on the X-ray films 1 year after the surgery or in the latest follow-up. The ODI was improved from ( 71.1±19.2 )%preoperatively to ( 22.0±11.3 )%postoperatively ( P<0.01 ). The VAS of low back pain was improved from ( 6.0±2.1 ) preoperatively to ( 2.2±1.7 ) postoperatively ( P<0.01 ). The VAS of lower leg pain was improved from ( 7.9±1.7 ) to ( 3.1±2.1 ) ( P<0.01 ). 39 of 42 patients got satisifed results, and the other 3 patients were basically content with the results.

    Economic development in developing societies characterized by industrialization, urbanization, and globalization has seen the emergence of an epidemic of diet- and life-style-related chronic degenerative diseases. A research project was initiated under the aegis of the International Atomic Energy Agency (IAEA), Vienna, Austria under its Coordinated Research Programme (CRP) to promote the use of stable isotopic techniques to document the extent of the problem and to understand the determinants of this epidemic. The principal objectives of this CRP involving countries both in the North and the South are to define the magnitude of the problem of obesity and non-insulin dependent diabetes mellitus (NIDDM) in developing countries, to identify the vulnerable groups at increased risk, and to attempt to describe the metabolic and physiological mechanisms underlying this phenomenon. These comparative international studies of obesity and NIDDM are looking at the effects of childhood malnutrition (Brazil) and socioeconomic differentials (Mexico) on adult risk factors; the composition of the daily diet on obesity (Chile); levels of patterns of physical activity of older adults (China) as well as their influence on weight gain and obesity (Cuba, Nigeria); the impact of body composition and energy expenditure on the evolution frank diabetes from impaired glucose tolerance (Jamaica), and of body compositional changes and the role of inflammatory cytokines on impaired glucose tolerance (India). The last study conducted in New Zealand was aimed at comparing the energy expenditures of Maori (Pacific Island) with New Zealanders of European descent.

    Immunologically-matched, induced pluripotent stem cell (iPSC)-derived photoreceptor precursor cells have the potential to restore vision to patients with retinal degenerative diseases like retinitis pigmentosa. The purpose of this study was to develop clinically-compatible methods for manufacturing photoreceptor precursor cells from adult skin in a non-profit cGMP environment. Biopsies were obtained from 35 adult patients with inherited retinal degeneration and fibroblast lines were established under ISO class 5 cGMP conditions. Patient-specific iPSCs were then generated, clonally expanded and validated. Post-mitotic photoreceptor precursor cells were generated using a stepwise cGMP-compliant 3D differentiation protocol. The recapitulation of the enhanced S-cone phenotype in retinal organoids generated from a patient with NR2E3 mutations demonstrated the fidelity of these protocols. Transplantation into immune compromised animals revealed no evidence of abnormal proliferation or tumor formation. These studies will enable clinical trials to test the safety and efficiency of patient-specific photoreceptor cell replacement in humans.

    Retinal degenerative diseases, including age-related macular degeneration and retinitis pigmentosa, are the prodominant causes of human blindness in the world; however, these diseases are difficult to treat. Currently, knowledge on the mechanisms of these diseases is still very limited and no radical drugs are available. Induced pluripotent stem (iPS) cells are an innovative technology that turns somatic cells into embryonic stem (ES)-like cells with pluripotent potential via the exogenous expression of several key genes. It can be used as an unlimited source for cell differentiation or tissue engineering, either of which is a promising therapy for human degenerative diseases. Induced pluripotent cells are both an unlimited source for retinal regeneration and an expectant tool for pharmaprojects and developmental or disease modelling. In this review, we try to summarize the advancement of iPS-based technologies and the potential utility for retinal degenerative diseases. We also discuss the challenges of using this technology in the retinology field.

    The aim of this article is to introduce a technique for lumbar intervertebral fusion that incorporates mobile microendoscopic discectomy (MMED) for lumbar degenerative disc disease. Minimally invasive transforaminal lumbar interbody fusion is frequently performed to treat degenerative diseases of the lumbar spine; however, the scope of such surgery and vision is limited by what the naked eye can see through the expanding channel system. To expand the visual scope and reduce trauma, we perform lumbar intervertebral fusion with the aid of a MMED system that provides a wide field through freely tilting the surgical instrument and canals. We believe that this technique is a good option for treating lumbar degenerative disc disease that requires lumbar intervertebral fusion.

    The surgical repair of degenerative mitral valve disease involves a number of technical points of importance. The use of artificial chordae for the repair of degenerative disease has increased as a part of the move from mitral valve replacement to repair of the mitral valve. The use of artificial chordae provides an alternative to the techniques pioneered by Carpentier (including the quadrangular resection, transfer of native chordae and papillary muscle shortening/plasty), which can be more technically difficult. Despite a growth in their uptake and the indications for their use, a number of challenges remain for the use of artificial chordae in mitral valve repair, particularly in the determination of the correct length to ensure optimal leaflet coaptation. Here, we analyse over 40 techniques described for artificial chordae mitral valve repair in the setting of degenerative disease. PMID:22962321

    Full Text Available Alkaptonuria is a rare, autosomal recessive disorder of phenylalanin/tyrosine metabolism due to congenital deficiency of the enzyme homogentisic acid oxidase. The diagnosis is clinical and the triad of homogentisic aciduria, ochronosis and precocious degenerative arthritis is characteristic. Its diagnosis in infancy and early therapeutic intervention help delaying its complications. These patients may remain undiagnosed until the darkening of urine soaked diapers is noticed or the early degenerative arthropathy develops. This paper describes two cases of alkaptonuria presenting late in life; one of them had associated hyperthyroidism.

    Cervical spondylosis is a broad term which describes the age related chronic disc degeneration, which can also affect the cervical vertebrae, the facet and other joints and their associated soft tissue supports. Evidence of spondylitic change is frequently found in many asymptomatic adults. Radiculopathy is a result of intervertebral foramina narrowing. Narrowing of the spinal canal can result in spinal cord compression, ultimately resulting in cervical spondylosis myelopathy. This review article examines the current literature in relation to the cervical spondylosis and describes the three clinical syndromes of axial neck pain, cervical radiculopathy and cervical myelopathy.

    Objective To determine if exercise therapy is superior to arthroscopic partial meniscectomy for knee function in middle aged patients with degenerative meniscal tears. Design Randomised controlled superiority trial. Setting Orthopaedic departments at two public hospitals and two physiotherapy clinics in Norway. Participants 140 adults, mean age 49.5 years (range 35.7–59.9), with degenerative medial meniscal tear verified by magnetic resonance imaging. 96% had no definitive radiographic evidence of osteoarthritis. Interventions 12 week supervised exercise therapy alone or arthroscopic partial meniscectomy alone. Main outcome measures Intention to treat analysis of between group difference in change in knee injury and osteoarthritis outcome score (KOOS4), defined a priori as the mean score for four of five KOOS subscale scores (pain, other symptoms, function in sport and recreation, and knee related quality of life) from baseline to two year follow-up and change in thigh muscle strength from baseline to three months. Results No clinically relevant difference was found between the two groups in change in KOOS4 at two years (0.9 points, 95% confidence interval −4.3 to 6.1; P=0.72). At three months, muscle strength had improved in the exercise group (P≤0.004). No serious adverse events occurred in either group during the two year follow-up. 19% of the participants allocated to exercise therapy crossed over to surgery during the two year follow-up, with no additional benefit. Conclusion The observed difference in treatment effect was minute after two years of follow-up, and the trial's inferential uncertainty was sufficiently small to exclude clinically relevant differences. Exercise therapy showed positive effects over surgery in improving thigh muscle strength, at least in the short term. Our results should encourage clinicians and middle aged patients with degenerative meniscal tear and no definitive radiographic evidence of osteoarthritis to consider supervised

    Full Text Available Abstract Background Nerve root decompression with instrumented spondylodesis is the most frequently performed surgical procedure in the treatment of patients with symptomatic low-grade spondylolytic spondylolisthesis. Nerve root decompression without instrumented fusion, i.e. Gill's procedure, is an alternative and less invasive approach. A comparative cost-effectiveness study has not been performed yet. We present the design of a randomised controlled trial on cost-effectiveness of decompression according to Gill versus instrumented spondylodesis. Methods/design All patients (age between 18 and 70 years with sciatica or neurogenic claudication lasting more than 3 months due to spondylolytic spondylolisthesis grade I or II, are eligible for inclusion. Patients will be randomly allocated to nerve root decompression according to Gill, either unilateral or bilateral, or pedicle screw fixation with interbody fusion. The main primary outcome measure is the functional assessment of the patient measured with the Roland Disability Questionnaire for Sciatica at 12 weeks and 2 years. Other primary outcome measures are perceived recovery and intensity of leg pain and low back pain. The secondary outcome measures include, incidence of re-operations, complications, serum creatine phosphokinase, quality of life, medical consumption, costs, absenteeism, work perception, depression and anxiety, and treatment preference. The study is a randomised prospective multicenter trial in which two surgical techniques are compared in a parallel group design. Patients and research nurse will not be blinded during the follow-up period of 2 years. Discussion Currently, nerve root decompression with instrumented fusion is the golden standard in the surgical treatment of low-grade spondylolytic spondylolisthesis, although scientific proof justifying instrumented spondylodesis over simple decompression is lacking. This trial is designed to elucidate the controversy in best

    Degenerative conditions of the lumbar spine are extremely common. Ninety percent of people over the age of 60 years have degenerative change on imaging; however, only a small minority of people will require spine surgery (Hicks et al. Spine (Phila Pa 1976) 34(12):1301-1306, 2009). This minority, however, constitutes a core element of spinal surgery practice. Whilst the patient outcomes from spinal surgeries have improved in recent years, some patients will remain with pain and disability despite technically successful surgery. Advances in regenerative medicine and stem cell therapies, particularly the use of mesenchymal stem cells and allogeneic mesenchymal precursor cells, have led to numerous clinical trials utilising these cell-based therapies to treat degenerative spinal conditions. Through cartilage formation and disc regeneration, fusion enhancement or via modification of pain pathways, stem cells are well suited to enhance spinal surgery practice. This review will focus on the outcomes of lumbar spinal procedures and the role of stem cells in the treatment of degenerative lumbar conditions to enhance clinical practice. The current status of clinical trials utilising stem cell therapies will be discussed, providing clinicians with an overview of the various cell-based treatments likely to be available to patients in the near future.

    Full Text Available Cumulatively, degenerative disease is one of the most fatal groups of diseases, and it contributes to the mortality and poor quality of life in the world while increasing the economic burden of the sufferers. Oxidative stress and inflammation are the major pathogenic causes of degenerative diseases such as rheumatoid arthritis (RA, diabetes mellitus (DM, and cardiovascular disease (CVD. Although a number of synthetic medications are used to treat these diseases, none of the current regimens are completely safe. Phytochemicals (polyphenols, carotenoids, anthocyanins, alkaloids, glycosides, saponins, and terpenes from natural products such as dietary fruits, vegetables, and spices are potential sources of alternative medications to attenuate the oxidative stress and inflammation associated with degenerative diseases. Based on in vitro, in vivo, and clinical trials, some of these active compounds have shown good promise for development into novel agents for treating RA, DM, and CVD by targeting oxidative stress and inflammation. In this review, phytochemicals from natural products with the potential of ameliorating degenerative disease involving the bone, metabolism, and the heart are described.

    Full Text Available The cerebellum is essentially involved in movement control and plays a critical role in motor learning. It has remained controversial whether patients with degenerative cerebellar disease benefit from high-intensity coordinative training. Moreover, it remains unclear by which training methods and mechanisms these patients might improve their motor performance. Here, we review evidence from different high-intensity training studies in patients with degenerative spinocerebellar disease. These studies demonstrate that high-intensity coordinative training might lead to a significant benefit in patients with degenerative ataxia. This training might be based either on physiotherapy or on whole-body controlled videogames (“exergames”. The benefit shown in these studies is equal to regaining one or more years of natural disease progression. In addition, first case studies indicate that even subjects with advanced neurodegeneration might benefit from such training programs. For both types of training, the observed clinical improvements are paralleled by recoveries in ataxia-specific dysfunctions (e.g., multijoint coordination and dynamic stability. Importantly, for both types of training, the retention of the effects seems to depend on the frequency and continuity of training. Based on these studies, we here present preliminary recommendations for clinical practice, and articulate open questions that might guide future studies on neurorehabilitation in degenerative spinocerebellar disease.

    To determine the effect of degenerative disease of the lumbar spine on bone mineral density in the lumbar spine and femoral neck. We reviewed radiographs and dual energy x-ray absorptiometry scans of the lumbar spine and hip in 305 Caucasian women with suspected osteoporosis. One hundred and eight-six patient remained after excluding women less than 40 years of age (n=18) and those with hip osteoarthritis, scoliosis, lumbar spine fractures, lumbar spinal instrumentation, hip arthroplasty, metabolic bone disease other than osteoporosis, or medications known to influence bone metabolism (n=101). On the basis of lumbar spine radiographs, those with absent/mild degenerative disease were assigned to the control group and those with moderate/severe degenerative disease to the degenerative group. Spine radiographs were evaluated for degenerative disease by two radiologists working independently; discrepant evaluations were resolved by consensus. Lumbar spine and femoral neck bone mineral density was compared between the two groups. Forty-five (24%) of 186 women were assigned to the degenerative group and 141 (76%) to the control group. IN the degenerative group, mean bone mineral density measured 1.075g/cm? in the spine and 0.788g/cm{sup 2} in the femoral neck, while for controls the corresponding figures were 0.989g/cm{sup 2} and 0.765g/cm{sup 2}. Adjusted for age, weight and height by means of analysis of variance, degenerative disease of the lumbar spine was a significant predictor of increased bone mineral density in the spine (p=0.0001) and femoral neck (p=0.0287). Our results indicate a positive relationship between degenerative disease of the lumbar spine and bone mineral density in the lumbar spine and femoral neck, and suggest that degenerative disease in that region, which leads to an intrinsic increase in bone mineral density in the femoral neck, may be a good negative predictor of osteoporotic hip fractures.

We assessed and compared the postoperative complications and clinical outcomes for patients aged 65 years and over (group A and patients aged 50–64 years (group B. Risk factors that could influence complications and clinical outcome were evaluated and statistically analyzed.Results: The postoperative complication rate was not significantly different between the two age groups (53% in group A and 40% in group B; however, group A had a significantly higher frequency of minor complications than group B, especially for urinary retention and postoperative delirium. A statistical relationship between diabetes mellitus and deep wound infection, one of the major complications of degenerative lumbar deformity surgery, was observed in both group A and group B. Male sex was a risk factor for urinary retention and long operative time, and abundant blood loss was a significant risk factor for postoperative delirium in group A.Conclusion: There were no significant differences in results for degenerative lumbar deformity surgery between patients older and younger than 65 years. However, diabetes mellitus showed a significant correlation with deep wound infection, which is one of the major complications of degenerative lumbar deformity surgery, and with urinary retention and postoperative delirium, which occurred frequently in patients aged older than 65 years

    Study Design Retrospective database analysis. Objective To assess the effect glycemic control has on perioperative morbidity and mortality in patients undergoing elective degenerative lumbar spine surgery. Summary of background data Diabetes Mellitus (DM) is a prevalent disease of glucose dysregulation that has been demonstrated to increase morbidity and mortality following spine surgery. However, there is limited understanding of whether glycemic control influences surgical outcomes in DM patients undergoing lumbar spine procedures for degenerative conditions. Methods The Nationwide Inpatient Sample was analyzed from 2002 to 2011. Hospitalizations were isolated based on International Classification of Diseases Ninth Revision, Clinical Modification procedural codes for lumbar spine surgery and diagnoses codes for degenerative conditions of the lumbar spine. Patients were then classified into three cohorts: controlled diabetics, uncontrolled diabetics and non-diabetics. Patient demographic data, acute complications and hospitalization outcomes were determined for each cohort. Results A total of 403,629 (15.7%) controlled diabetics and 19,421(0.75%) uncontrolled diabetics underwent degenerative lumbar spine surgery from 2002-2011. Relative to non-diabetics, uncontrolled diabetics had significantly increased odds of cardiac complications, deep venous thrombosis and post-operative shock; additionally, uncontrolled diabetics also had an increased mean length of stay (approximately 2.5 days), greater costs (1.3-fold) and a greater risk of inpatient mortality (odds ratio=2.6, 95% confidence interval=1.5-4.8, p degenerative lumbar spine surgery leads to increased risk of acute complications and poor outcomes. Patients with uncontrolled DM, or poor glucose control, may benefit from improving glycemic control prior to surgery. PMID:24983935

    Congenital fusion of cervical vertebrae, including Klippel-Feil syndrome (KFS), is a suspected risk factor for development of degenerative cervical myelopathy (DCM). We aimed to establish prevalence and degenerative patterns of congenital cervical fusion (CCF) among a global cohort of patients with DCM. Data from 3 prospective DCM studies were merged, including clinical data for 813 patients and imaging for 592 patients. CCF was diagnosed by presence of fused cervical vertebrae without signs of degenerative fusion. A wasp-waist sign was used to define a KFS subgroup. Characteristics of patients with CCF and the KFS subgroup were compared with the remainder of patients with DCM. Twenty-three patients with CCF (14 KFS) were identified, indicating a prevalence of 3.9% (2.4% KFS). Patients with CCF were older (P = 0.02), had more operated levels (P = 0.01), had higher rates of ossified posterior longitudinal ligament (P = 0.02), and demonstrated worse degenerative changes at C3-4, including spinal cord compression (P = 0.002) and T2 weighted image T2WI signal hyperintensity (P = 0.04). Levels adjacent to fusions showed a trend toward increased spinal cord compression (P = 0.09), with fusions at C3-4 or above showing cord compression below in 9 of 10 patients, fusions at C5-6 or below having cord compression above in 8 of 8 patients, and fusions at C4-5 showed cord compression above and below in 2 of 2 patients. The prevalence of CCF and KFS is higher in DCM than for the general population, suggesting that these patients are predisposed to DCM development. Patients with CCF also have an altered pattern of degenerative changes, seemingly related to adjacent segment degeneration that preferentially affects midcervical levels.

    Background and Purpose: The etiologic diagnosis of parkinsonian syndromes is of particular importance when considering syndromes of vascular or degenerative origin. The purpose of this study is to find differences in the white-matter architecture between those two groups in elderly patients. Materials and Methods: Thirty-five patients were prospectively included (multiple-system atrophy, n = 5; Parkinson's disease, n = 15; progressive supranuclear palsy, n = 9; vascular parkinsonism, n = 6), with a mean age of 76 years. Patients with multiple-system atrophy, progressive supranuclear palsy and Parkinson's disease were grouped as having parkinsonian syndromes of degenerative origin. Brain MRIs included diffusion tensor imaging. Fractional anisotropy and mean-diffusivity maps were spatially normalized, and group analyses between parkinsonian syndromes of degenerative origin and vascular parkinsonism were performed using a voxel-based approach. Results: Statistical parametric-mapping analysis of diffusion tensor imaging data showed decreased fractional anisotropy value in internal capsules bilaterally in patients with vascular parkinsonism compared to parkinsonian syndromes of degenerative origin (p = 0.001) and showed a lower mean diffusivity in the white matter of the left superior parietal lobule (p = 0.01). Fractional anisotropy values were found decreased in the middle cerebellar peduncles in multiple-system atrophy compared to Parkinson's disease and progressive supranuclear palsy. The mean diffusivity was increased in those regions for these subgroups. Conclusion: Clinically defined vascular parkinsonism was associated with decreased fractional anisotropy in the deep white matter (internal capsules) compared to parkinsonian syndromes of degenerative origin. These findings are consistent with previously published neuropathological data.

    Canine degenerative myelopathy (DM) is a progressive, adult-onset, multisystem degenerative disease with many features in common with amyotrophic lateral sclerosis (ALS). As with some forms of ALS, DM is associated with mutations in superoxide dismutase 1 (SOD1). Clinical signs include general proprioceptive ataxia and spastic upper motor neuron paresis in pelvic limbs, which progress to flaccid tetraplegia and dysphagia. The purpose of this study was to characterize DM as a potential disease model for ALS. We previously reported that intercostal muscle atrophy develops in dogs with advanced-stage DM. To determine whether other components of the thoracic motor unit (MU) also demonstrated morphological changes consistent with dysfunction, histopathologic and morphometric analyses were conducted on thoracic spinal motor neurons (MNs) and dorsal root ganglia (DRG) and in motor and sensory nerve root axons from DM-affected boxers and Pembroke Welsh corgis (PWCs). No alterations in MNs or motor root axons were observed in either breed. However, advanced-stage PWCs exhibited significant losses of sensory root axons, and numerous DRG sensory neurons displayed evidence of degeneration. These results indicate that intercostal muscle atrophy in DM is not preceded by physical loss of the motor neurons innervating these muscles, nor of their axons. Axonal loss in thoracic sensory roots and sensory neuron death suggest that sensory involvement may play an important role in DM disease progression. Further analysis of the mechanisms responsible for these morphological findings would aid in the development of therapeutic intervention for DM and some forms of ALS.

  11. Adult flatfoot.

    Toullec, E

    2015-02-01

    Adult flatfoot is defined as a flattening of the medial arch of the foot in weight-bearing and lack of a propulsive gait. The 3 lesion levels are the talonavicular, tibiotarsal and midfoot joints. The subtalar joint is damaged by the consequent rotational defects. Clinical examination determines deformity and reducibility, and assesses any posterior tibialis muscle deficit, the posterior tibialis tendon and spring ligament being frequently subject to degenerative lesions. Radiographic examination in 3 incidences in weight-bearing is essential, to determine the principal level of deformity. Tendon (posterior tibialis tendon) and ligamentous lesions (spring ligament and interosseous ligament) are analyzed on MRI or ultrasound. In fixed deformities, CT explores for arthritic evolution or specific etiologies. 3D CT reconstruction can analyze bone and joint morphology and contribute to the planning of any osteotomy. Medical management associates insoles and physiotherapy. Acute painful flatfoot requires strict cast immobilization. Surgical treatment associates numerous combinations of procedures, currently under assessment for supple flatfoot: for the hindfoot: medial slide calcaneal osteotomy, calcaneal lengthening osteotomy, or arthroereisis; for the midfoot: arthrodesis on one or several rays, or first cuneiform or first metatarsal osteotomy; for the ankle: medial collateral ligament repair with tendon transfer. Fixed deformities require arthrodesis of one or several joint-lines in the hindfoot; for the ankle, total replacement after realignment of the foot, or tibiotalocalcaneal fusion or ankle and hindfoot fusion; and, for the midfoot, cuneonavicular or cuneometatarsal fusion. Tendinous procedures are often associated. Specific etiologies may need individualized procedures. In conclusion, adult flatfoot tends to be diagnosed and managed too late, with consequent impact on the ankle, the management of which is complex and poorly codified.

    Human pluripotent stem cells represent a unique source for cell-based therapies and regenerative medicine. The intrinsic features of these cells such as their easy accessibility and their capacity to be expanded indefinitely overcome some limitations of conventional adult stem cells. Furthermore, the possibility to derive patient-specific induced pluripotent stem (iPS) cells in combination with the current development of gene modification methods could be used for autologous cell therapies of some genetic diseases. In particular, muscular dystrophies are considered to be a good candidate due to the lack of efficacious therapeutic treatments for patients to date, and in view of the encouraging results arising from recent preclinical studies. Some hurdles, including possible genetic instability and their efficient differentiation into muscle progenitors through vector/transgene-free methods have still to be overcome or need further optimization. Additionally, engraftment and functional contribution to muscle regeneration in pre-clinical models need to be carefully assessed before clinical translation. This review offers a summary of the advanced methods recently developed to derive muscle progenitors from pluripotent stem cells, as well as gene therapy by gene addition and gene editing methods using ZFNs, TALENs or CRISPR/Cas9. We have also discussed the main issues that need to be addressed for successful clinical translation of genetically corrected patient-specific pluripotent stem cells in autologous transplantation trials for skeletal muscle disorders.

    1997-07-01

    Thirty stranded beluga whales (Delphinapterus leucas) from the St. Lawrence Estuary (Quebec, Canada) population and five animals from the Hudson Bay aboriginal hunt (North-west Territories, Canada) were examined. Twenty one animals from the St. Lawrence Estuary had mild to severe adrenal lesions and four whales from the Hudson Bay population were affected by minimal adrenal changes. Cortical hyperplasia was observed in 24 adult beluga whales all from the St. Lawrence Estuary. Bilateral cortical cysts and cellular vacuolar degeneration were observed in the adrenal glands of 19 beluga whales from both populations. The cysts, filled with a cortisol-rich liquid, were present in both sexes. Beluga whales with adrenal cysts were significantly older than animals without cysts, and the severity of the lesions increased with age. Nodular hyperplasia of the medulla was observed in seven of the beluga whales, all from the St. Lawrence Estuary population. All lesions could be part of a normal aging process. The adrenocortical lesions might be due to stress or adrenocorticolytic xenobiotics, while the medullary hyperplasia might be caused by hypoxia or exposure to estrogenic xenobiotics.

    Degeneration of the intervertebral disc is a common disease in the adults, especially at advanced age. A causal therapy is not known, but the progress in new therapeutic strategies, for example in tissue engineering, shows new possibilities. The goal of our study was to develop a new animal model that stimulates a load induced degeneration of the disc. We used the New Zealand rabbit, because morphology is similar to the human intervertebral disc. The degeneration was induced by axial compression of the disc L4 - L5 with an external fixateur. After different loading intervals, the animals were sacrified and the discs examined by radiology, histology, apoptosis and biomechanical testing. Radiography showed a significant decrease of the disc thickness in all loaded groups. Morphologically the intervertebral discs of loaded rabbits showed degenerative changes which were comparable to those in humans. A significantly increased number of dead cells in the annulus occurred after 14 and 28 days loading compared to the controls. The bending stress measured as the load to failure was not significantly different between the unloaded discs and the 28 days loaded discs. The results show that our animal modell can create degeneration. Four weeks compression leads to significant degeneration. Degeneration of the discs persisted in animals that were allowed a recovery time of 28 days after 28 days of loading.

    Introduction Degenerative lumbar spinal stenosis (DLSS) is a major public health problem and the primary reason why older adults seek lumbar spine surgery. Acupuncture may be effective for DLSS, but the evidence supporting this possibility is still limited. Methods and analysis A total of 80 participants with DLSS will be randomly allocated to either an acupuncture group or a sham acupuncture (SA) group at a ratio of 1:1. 24 treatments will be provided over 8 weeks. The primary outcome is the score change of the Modified Roland-Morris Disability Questionnaire (RMDQ) responses from baseline to week 8. The secondary outcomes include the assessment of lower back pain and leg pain using the Numeric Rating Scale (NRS), the change in the number of steps per month, and the assessment of the specific quality of life using the Swiss Spinal Stenosis Questionnaire (SSSQ). We will follow-up with the participants until week 32. All of the participants who received allocation will be included in the statistical analysis. Ethics/dissemination This protocol has been approved by the Research Ethical Committee of Guang'anmen Hospital (Permission number: 2015EC114) and Fengtai Hospital of Integrated Traditional and Western Medicine (Permission number: 16KE0409). The full data set will be made available when this trial is completed and published. Applications for the release of data should be made to ZL (principal investigator).

    Objective To explore the change of the sagittal alignment of the spine and pelvis before and after surgery for isthmic lumbar spondylolisthesis. Methods Spondylolisthesis patients,who underwent surgical posterior interver-tebral fusion combined with pedicle screw fixation,were retrospectively reviewed. The pre-and post-operative radio-graphic parameters,such as thoracic kyphosis(TK),thoracolumbar junction angle(TLJ)sagittal vertical axis(SVA), spino-sacral angle(SSA),lumbar lordosis(LL),sacral slope (SS),pelvic incidence(PI) and pelvic tilt (PT) were measured. Changes of preoperative and postoperative radiographic parameters were evaluated. Pearson′s correlation coeffieients were used to investigate the association of all parameters. Results PI,TLJ and TK were unaffected by surgery. The alteration of SSA showed significant correlation with the change of PT,PI,LL,SS and SVA. Conclusions Surgical posterior intervertebral fusion combined with pedicle screw fixation of spondylolisthesis can effectively im-prove and maintain the spinal sagittal parameters. SSA is closely related with good clinical outcome,which can be a reference for evaluating spinopelvic sagittal alignment balance and operation strategy.%目的:研究腰椎峡部裂滑脱症患者手术治疗前后脊柱骨盆矢状位影像学参数变化。方法回顾分析54例施行单节段腰椎椎间 cage 融合术治疗的腰椎峡部裂滑脱患者资料,术前及随访时拍摄站立位脊柱全长正、侧位 X 线片,测量手术前后胸椎后凸(TK)、胸腰联合角(TLJ)、C7矢状面平衡(SVA)、脊柱-骨盆角(SSA)、腰椎前凸角(LL)、骶骨倾斜角(SS)、骨盆倾斜角(PT)和骨盆入射角(PI),并应用 Pearson 相关系数对影像学结果进行相关分析。结果脊柱-骨盆相关参数中,除 PI、TLJ 和 TK 外,其余参数手术前后比较差异均有统计学意义(P <0.05,P <0.01)。 SSA 的变化与 PT、PI、LL、SS 及 SVA 的变化存在线性关系。结论腰椎

Following induction of arthritis, the treatment group received intra-articular BoNT/B. Arthritic control groups were treated with intra-articular normal saline or sham injections. Pain behavior testing was performed prior to arthritis, after induction of arthritis, and following treatments. Pain behavior measures included analysis of gait impairment (spontaneous pain behavior and joint tenderness evaluation (evoked pain response. Strength was measured as ability to grasp and cling.Results: Visual gait analysis showed significant impairment of gait in arthritic mice that improved 43% after intra-articular BoNT/B, demonstrating a substantial articular analgesic effect. Joint tenderness, measured with evoked pain response scores, increased with arthritis induction and decreased 49.5% after intra-articular BoNT/B treatment. No improvement in visual gait scores or decrease in evoked pain response scores were found in the control groups receiving intra-articular normal saline or sham injections. Intra-articular BoNT/B was safe, and no systemic effects or limb weakness was noted.Conclusions: This study is the first report of intra-articular BoNT/B for analgesia in a murine model of arthritis pain. The results of this study validate prior work using intra-articular neurotoxins in murine models. Our findings show chronic degenerative arthritis

The most important definitions as well as short descriptions of the etiopathology and clinical presentation of DSD are provided first, followed by an overview of conventional and advanced imaging methods that are used in DSD. The authors then discuss in detail the imaging patterns of particular types of degenerative changes. Finally, the current imaging algorithm in DSD is presented. The imaging method of choice is magnetic resonance, including advanced techniques--especially diffusion tensor imaging. Other imaging methods (plain radiography, computed tomography, vascular studies, scintigraphy, positron emission tomography, discography) play a supplementary role ).

    Pedicle screw and rod instrumentation has become the preferred technique for performing stabilization and fusion in the surgical treatment of lumbar spine degenerative disease. Rigid fixation leads to high fusion rates but may also contribute to stress shielding and adjacent segment degeneration. Thus, the use of semirigid rods made of polyetheretherketone (PEEK) has been proposed. Although the PEEK rods biomechanical properties, such as anterior load sharing properties, have been shown, there are few clinical studies evaluating their application in the lumbar spine surgical treatment. This study examined a retrospective cohort of patients who underwent posterior lumbar fusion for degenerative disease using PEEK rods, in order to evaluate the clinical and radiological outcomes and the incidence of complications.

    Degenerative retinal diseases affect millions of people worldwide, which can lead to the loss of vision. However, therapeutic approaches that can reverse this process are limited. Recent efforts have allowed the possibility of the stem cell-based regeneration of retinal cells and repair of injured retinal tissues. Although the direct differentiation of pluripotent stem cells into terminally differentiated photoreceptor cells comprises one approach, a series of studies revealed the intrinsic regenerative potential of the retina using endogenous retinal stem cells. Muller glial cells, ciliary pigment epithelial cells, and retinal pigment epithelial cells are candidates for such retinal stem cells that can differentiate into multiple types of retinal cells and be integrated into injured or developing retina. In this review, we explore our current understanding of the cellular identity of these candidate retinal stem cells and their therapeutic potential for cell therapy against degenerative retinal diseases.

    A patient is presented in whom a focal reduction in marrow activity in the lumbar spine on both leucocyte and nanocolloid marrow scintigraphy was subsequently shown to be due to fatty infiltration of marrow in association with disc degeneration. Degenerative disease in the lumbar spine has not been previously described as a cause of abnormal bone marrow distribution by such means and needs to be distinguished from a more serious pathology, such as malignant infiltration and vertebral infection, which it may mimic. In a retrospective review of 33 nanocolloid bone marrow and 117 leucocyte scintigrams, 8 showed a degree of reduced marrow activity in the lumbar spine consistent with that caused by degenerative changes.

    Neuroimaging offers a powerful means to assess the trajectory of brain degeneration in a variety of disorders, including Alzheimer's disease (AD). Here we describe how multi-modal imaging can be used to study the changing brain during the different stages of AD. We integrate findings from a range of studies using magnetic resonance imaging (MRI), positron emission tomography (PET), functional MRI (fMRI) and diffusion weighted imaging (DWI). Neuroimaging reveals how risk genes for degenerative disorders affect the brain, including several recently discovered genetic variants that may disrupt brain connectivity. We review some recent neuroimaging studies of genetic polymorphisms associated with increased risk for late-onset Alzheimer's disease (LOAD). Some genetic variants that increase risk for drug addiction may overlap with those associated with degenerative brain disorders. These common associations offer new insight into mechanisms underlying neurodegeneration and addictive behaviors, and may offer new leads for treating them before severe and irreversible neurological symptoms appear.

    We successfully designed and validated degenerative primers for turkey genes MUC2, RPS13, TBP and TFF2 based on chicken sequences in order to use gene transcription analysis to evaluate (quantify) the mucin transcription to probiotic supplementation in turkeys. Primers were designed for the genes MUC2, TFF2, RPS13 and TBP using a degenerative primer design method based on the available Gallus gallus sequences. All primer sets, which produced a single PCR amplicon of the expected sizes, were cloned into the TOPO(®) vector and then transformed into TOP 10(®) competent cells. Plasmid DNA isolation was performed on the TOP10(®) cell culture and sent for sequencing. Sequences were analyzed using NCBI BLAST. All genes sequenced had over 90% homology with both the chicken and predicted turkey sequences. The sequences were used to design new 100% homologous primer sets for the genes of interest. © 2016 Poultry Science Association Inc.

    Parallel imaging techniques such as GRAPPA have been introduced to optimize image quality and acquisition time. For spinal imaging in a clinical setting no data exist on the equivalency of conventional and parallel imaging techniques. The purpose of this study was to determine whether T1- and T2-weighted GRAPPA sequences are equivalent to conventional sequences for the evaluation of degenerative lumbar spine disease in terms of image quality and artefacts. In patients with clinically suspected degenerative lumbar spine disease two neuroradiologists independently compared sagittal GRAPPA (acceleration factor 2, time reduction approximately 50%) and non-GRAPPA images (25 patients) and transverse GRAPPA (acceleration factor 2, time reduction approximately 50%) and non-GRAPPA images (23 lumbar segments in six patients). Comparative analyses included the minimal diameter of the spinal canal, disc abnormalities, foraminal stenosis, facet joint degeneration, lateral recess, nerve root compression and osteochondrotic vertebral and endplate changes. Image inhomogeneity was evaluated by comparing the nonuniformity in the two techniques. Image quality was assessed by grading the delineation of pathoanatomical structures. Motion and aliasing artefacts were classified from grade 1 (severe) to grade 5 (absent). There was no significant difference between GRAPPA and non-accelerated MRI in the evaluation of degenerative lumbar spine disease (P > 0.05), and there was no difference in the delineation of pathoanatomical structures. For inhomogeneity there was a trend in favour of the conventional sequences. No significant artefacts were observed with either technique. The GRAPPA technique can be used effectively to reduce scanning time in patients with degenerative lumbar spine disease while preserving image quality. (orig.)

    Physiotherapy plays an important role in the management of patients with degenerative cerebellar ataxias. However, our insight in the quantity and quality of physiotherapy prescription in this group of patients is incomplete. The purposes of this study were to investigate the utilization of physiotherapy and patient satisfaction in patients with degenerative ataxias in The Netherlands and to examine the level of expertise and needs of physiotherapists treating ataxia patients. Questionnaires were sent to members of the Dutch association for patients with degenerative cerebellar ataxias (n = 532). In addition, 181 questionnaires were sent to the physiotherapists who had recently treated the patients who responded. Eventually, 317 questionnaires from patients (60 %) and 114 questionnaires from physiotherapists (63 %) could be used for further analysis. Sixty-four percent of the patients were currently treated by a physiotherapist. Their median treatment duration was 5 years. Nineteen percent of the patients had never been referred, often despite the presence of limitations in daily activities. On the other hand, some participants without reported limitations had received physiotherapy. In general, participants were satisfied with their physiotherapist. The most reported treatment goals were improvement or maintenance of balance, general physical condition, and mobility. Physiotherapists reported lack of ataxia-specific expertise and expressed the need for education and evidence-based guidelines. Referral to and use of physiotherapy in patients with degenerative cerebellar ataxia in The Netherlands are currently inconsistent and not in agreement with the little scientific evidence available. Referral rates are high, but referrals and actual necessity are discrepant; treatment duration is long; and ataxia-specific expertise among physiotherapists is insufficient. Evidence-based recommendations and specific training of physiotherapists are needed.

    Aging of the spine is characterized by facet joints arthritis, degenerative disc disease and atrophy of extensor muscles resulting in a progressive kyphosis. Recent studies confirmed that patients with lumbar degenerative disease were characterized by an anterior sagittal imbalance, a loss of lumbar lordosis and an increase of pelvis tilt. The aim of this paper was thus to describe the different compensatory mechanisms which are observed in the spine, pelvis and/or lower limbs areas for patients with severe degenerative spine. We reviewed all the compensatory mechanisms of sagittal unbalance described in the literature. According to the severity of the imbalance, we could identify three different stages: balanced, balanced with compensatory mechanisms and imbalanced. For the two last stages, the compensatory mechanisms permitted to limit consequences of lumbar kyphosis on the global sagittal alignment. Reduction of thoracic kyphosis, intervertebral hyperextension, retrolisthesis, pelvis backtilt, knee flessum and ankle extension were the main mechanisms described in the literature. The basic concept of these compensatory mechanisms was to extend adjacent segments of the kyphotic spine allowing for compensation of anterior translation of the axis of gravity. To avoid underestimate the severity of the degenerative spine disorder, it thus seems important to recognize the different compensatory mechanisms from the upper part of the trunk to the lower limbs. We propose a three steps algorithm to analyse the balance status and determine the presence or not of these compensatory mechanisms: measurement of pelvis incidence, assessment of global sagittal alignment and analysis of compensatory mechanisms successively in the spine, pelvis and lower limbs areas.

    Full Text Available Traumatic high-grade spondylolisthesis in subaxial cervical spine is frequently associated with acute spinal cord injury and quadriparesis. There have been rare cases where such pathology demonstrates minimal to no neurological deficits. Assessment of the underlying biomechanics may provide insight into the mechanism of injury and associated neurological preservation. Patient 1 is a 63-year-old female presenting after a motor vehicle collision with significant right arm pain without neurological deficits. Imaging demonstrated C7/T1 spondyloptosis, associated with a locked facet on the left at C6/7 and a locked facet on the right at C7/T1, with a fracture of the left C7 pedicle and right C7 lamina. Patient 2 is a 60-year-old male presenting after a bicycle collision with transient bilateral upper extremity paresthesias without neurological deficits. Imaging demonstrated C7/T1 spondyloptosis, with fractures of bilateral C7 pedicles, C7/T1 facets, and C7 lamina. Patient 3 is a 36-year-old male presenting after a motor vehicle collision with diffuse tingling sensation throughout all extremities. His neurological examination was nonfocal. Imaging demonstrated a grade 4 spondylolithesis at C7/T1, associated with bilateral C7/T1 locked facets. From literature, most cases were noted to be dislocations resulting from fractures of the posterior elements. A minority of cases has been found to involve facet dislocations without fractures. Further biomechanical studies are needed to understand the underlying mechanisms.

  4. X-ray diagnosis of post-traumatic degenerative-dystrophic lesions of the vertebrae

    Immediate and long-term consequences of the spinal injury have been studied in 221 patients aged 13 to 70 years, applying clinical and radiological methods. Various degenerative-dystrophic alterations have been frequently found at the level of the damaged spinal segment and included cartilaginous knots and discal hernia and fibrosis, local spondylosis and spondylarthrosis, osteochondrosis, calcification of the disk and ligamentous apparatus. These pathologic changes infrequently cause patients' complaints and neurological disturbances. The degenerative-dystrophic processes in the spine, following an acute injury manifest no specific features, except for some peculiarities of the traumatic cartilaginous knot (greater size and depth, partial hanging of the obturating plate over the knot bed). The type and gravity of the fracture, the degree of static-dynamic disorders of the vertebral column and, to some extent, the patient's age most significantly determine the development of the degenerative-dystrophic processes in the damaged spinal segment. Post-traumatic clinicofunctional examination of the spine has been proved important.

  5. Is there a role for wine in cancer and the degenerative diseases of aging?

    Full Text Available Creina S StockleyThe Australian Wine Research Institute, Adelaide, South Australia, AustraliaAbstract: Population aging is associated with the increased incidence cancer and of degenerative diseases. Population aging is occurring on a global scale, with faster aging projected for the coming decades than has occurred in the past. Globally, the population aged 60 years and over is projected to nearly triple by 2050, while the population aged 80 years and over is projected to experience a more than fivefold increase. Increased numbers of older individuals may have implications for associated expenditure on income support, housing and health services, although a healthy, independent older population can also form a valued social resource, for example in providing care for others, sharing skills and knowledge, and engaging in volunteer activities. Simple dietary measures such as moderate wine consumption to supplement a healthy exercise and nutrition routine, or as an adjunct to prescription medicines when appropriate, are thus needed to maintain an aging population. The role of wine in cancer and the degenerative diseases of aging is thus discussed.Keywords: population aging, wine, degenerative disease, cancer
