Distal junctional failure after corrective surgery without pelvic fixation for thoracolumbar junctional kyphosis due to osteoporotic vertebral fracture. J Orthop Sci 2024; 29:781-787. [PMID: 36931977 DOI: 10.1016/j.jos.2023.03.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/13/2022] [Revised: 02/23/2023] [Accepted: 03/01/2023] [Indexed: 03/19/2023]
Abstract
BACKGROUND Thoracolumbar junctional kyphosis (TLJK) due to osteoporotic vertebral fracture (OVF) negatively impacts patients' quality of life. The necessity of pelvic fixation in corrective surgery for TLJK due to OVF remains controversial. This study aimed to: 1) evaluate the surgical outcomes of major corrective surgery for thoracolumbar junctional kyphosis due to osteoporotic vertebral fracture, and 2) identify the risk factors for distal junctional failure to identify potential candidates for pelvic fixation. METHODS Patients who underwent surgical correction (fixed TLJK>40°, OVF located at T11-L2, the lowermost instrumented vertebra at or above L5) were included. Sagittal vertical axis, pelvic tilt, pelvic incidence, thoracic kyphosis, lumbar lordosis (L1-S1), local kyphosis, and lower lumbar lordosis (L4-S1) were assessed. Proximal and distal junctional kyphosis (P/DJK) and failures (P/DJF) were evaluated. Pre/postoperative spinopelvic parameters were compared between DJF and non-DJF patients. RESULTS Thirty-one patients (mean age: 72.3 ± 7.9 years) were included. PJK was observed in five patients (16.1%), while DJK in 11 (35.5%). Twelve cases (38.7%) were categorized as failure. Among the patients with PJK, there was only one patient (20%) categorized as PJF and required an additional surgery. Contrary, all of eleven patients with DJK were categorized as DJF, among whom six (54.5%) required additional surgery for pelvic fixation. In comparisons between DJF and non-DJF patients, there was no significant difference in pre/postoperative LK (pre/post, p = 0.725, p = 0.950). However, statistically significant differences were observed in the following preoperative alignment parameters: SVA (p = 0.014), LL (p = 0.001), LLL (p = 0.006), PT (p = 0.003), and PI-LL (p < 0.001). CONCLUSIONS Spinopelvic parameters, which represent the compensatory function of lumbar hyperlordosis and pelvic retroversion, have notable impacts on surgical outcomes in correction surgery for TLJK due to OVF. Surgeons should consider each patient's compensatory function when choosing a surgical approach.

Stiffness and Strain Properties Derived From Digital Tomosynthesis-Based Digital Volume Correlation Predict Vertebral Strength Independently From Bone Mineral Density. J Biomech Eng 2023; 145:041009.

Abstract
Vertebral fractures are the most common osteoporotic fractures, but their prediction using standard bone mineral density (BMD) measurements from dual energy X-ray absorptiometry (DXA) is limited in accuracy. Stiffness, displacement, and strain distribution properties derived from digital tomosynthesis-based digital volume correlation (DTS-DVC) have been suggested as clinically measurable metrics of vertebral bone quality. However, the extent to which these properties correlate to vertebral strength is unknown. To establish this relationship, two independent experiments, one examining isolated T11 and the other examining L3 vertebrae within the L2-L4 segments from cadaveric donors were utilized. Following DXA and DTS imaging, the specimens were uniaxially compressed to fracture. BMD, bone mineral content (BMC), and bone area were recorded for the anteroposterior and lateromedial views from DXA, stiffness, endplate to endplate displacement and distribution statistics of intravertebral strains were calculated from DTS-DVC and vertebral strength was measured from mechanical tests. Regression models were used to examine the relationships of strength with the other variables. Correlations of BMD with vertebral strength varied between experimental groups (R2adj = 0.19-0.78). DTS-DVC derived properties contributed to vertebral strength independently from BMD measures (increasing R2adj to 0.64-0.95). DTS-DVC derived stiffness was the best single predictor (R2adj = 0.66, p < 0.0001) and added the most to BMD in models of vertebral strength for pooled T11 and L3 specimens (R2adj = 0.95, p < 0.0001). These findings provide biomechanical relevance to DTS-DVC calculated properties of vertebral bone and encourage further efforts in the development of the DTS-DVC approach as a clinical tool.

Abstract
Hundred and twenty four females with spondylolisthesis were divided into three groups (A group: anterolisthesis; P group: retrolisthesis; and AP group: antero-retrolisthesis), We reviewed their whole-spine radiographs and measured their standard sagittal parameters, including thoracic kyphosis (TK), pelvic incidence (PI), lumbar lordosis (LL), pelvic tilt (PT), and sacral slope (SS). The muscle strengths of the trunk flexor, trunk extensor, iliopsoas, and quadriceps were measured. Health-related quality of life was assessed using the Short Form 36-item Health Survey-physical component summary (SF-36 PCS). PI, SS, and LL-TK of participants in the P group were significantly lower than those in the A and AP groups (PI: P group vs. A group, p < 0.001, P group vs. AP group, p = 0.01), (SS: P group vs. A group, p = 0.001, P group vs. AP group, p = 0.003), (LL-TK: P group vs. A group, p < 0.001, P group vs. AP group, p = 0.049). TK of participants in the P and AP groups was greater than that of those in the A group. (P group vs. A group, p = 0.04, AP group vs. A group, p = 0.0025). The SF-36 PCS score in the P group was lower than that in the A and AP groups. (P group vs. A group, p = 0.004, P group vs. AP group, p = 0.012). The muscle strengths of the trunk flexor and trunk extensor and quadriceps in the P group were lower than those in the A groups. (Trunk flexor: P group vs. A group, p = 0.012), (Trunk extensor: P group vs. A group, p = 0.018), (Quadriceps: P group vs. A group, p = 0.011). In conclusion, female participants with degenerative retrolisthesis had a smaller PI and SS and a larger TK, along with decreased physical function and QoL scores than those with anterolisthesis.

Abstract
Background:
Osteoporotic vertebral fractures (OVF) commonly occur at the thoracolumbar junction, but are less frequently encountered in the mid-thoracic region. Here, a 69-year-old female presented with back pain and the new onset of symptoms characterized by the inability to belch.
Case Description:
A 69-year-old female presented with back pain. 2 months later, she developed anorexia and difficulty belching. The thoracic magnetic resonance (MR) demonstrated a T7 OVF. As she ultimately underwent a balloon kyphoplasty (BKP), as conservative treatment was unsuccessful.
Conclusion:
OVF should be suspected in elderly females with the inability to belch accompanied by chest and back pain. The diagnosis is best established with a spinal MR imaging and should be followed by BKP.

Abstract
BACKGROUND Adjuvant tegafur-uracil therapy has prolonged postoperative survival in patients with non-small cell lung cancer. Some patients experience treatment discontinuation due to gastrointestinal disorders such as anorexia, and the associated factors and the impact of lobectomy remain unclear. This study aimed to assess the postoperative esophageal displacement after lobectomy and to clarify its impact on the continuity of tegafur-uracil treatment. METHODS Patients who received adjuvant tegafur-uracil therapy after lobectomy between April 2009 and March 2019 were retrospectively analyzed. Patient background, perioperative characteristics, treatment findings, and the degree of esophageal displacement measured by computed tomography were compared between the treatment completion group and the discontinuation group. A subgroup comparative analysis was further performed in the groups divided according to the degree of esophageal displacement. RESULTS A total of 68 patients were reviewed, including 41 males and 27 females with a mean age of 66.2 years old. A total of 41 patients completed the 2-year adjuvant treatment and 27 patients discontinued it. The overall survival and relapse-free survival between the two groups were statistically significant (p = 0.027, p = 0.010). The degree of esophageal displacement at the Th7 level was a significant predictor of treatment discontinuation (p = 0.046, odds ratio [OR]: 1.138, 95% confidence interval [CI]: 1.002-1.291). Among the patients with a high degree of esophageal displacement above the baseline determined from the receiver operating characteristic curve, the cause of discontinuation was anorexia, which was significant in multivariate analysis (p = 0.013, OR: 14.72, 95% CI: 1.745-124.2). CONCLUSIONS Our study suggested that anatomical displacement of the esophagus after lobectomy may affect the discontinuation of oral adjuvant chemotherapy in patients with lung cancer.

Abstract
Vertebral fractures are the most common osteoporotic fractures, but clinical means for assessment of vertebral bone integrity are limited in accuracy, as they typically use surrogate measures that are indirectly related to mechanics. The objective of this study was to examine the extent to which intravertebral strain distributions and changes in cancellous bone texture generated by a load of physiological magnitude can be characterized using a clinically available imaging modality. We hypothesized that digital tomosynthesis-based digital volume correlation (DTS-DVC) and image texture-based metrics of cancellous bone microstructure can detect development of mechanical strains under load. Isolated cadaveric T11 vertebrae and L2-L4 vertebral segments were DTS imaged in a nonloaded state and under physiological load levels. Axial strain, maximum principal strain, maximum compressive and tensile principal strains, and von Mises equivalent strain were calculated using the DVC technique. The change in textural parameters (line fraction deviation, anisotropy, and fractal parameters) under load was calculated within the cancellous centrum. The effect of load on measured strains and texture variables was tested using mixed model analysis of variance, and relationships of strain and texture variables with donor age, bone density parameters, and bone size were examined using regression models. Magnitudes and heterogeneity of intravertebral strain measures correlated with applied loading and were significantly different from background noise. Image texture parameters were found to change with applied loading, but these changes were not observed in the second experiment testing L2-L4 segments. DTS-DVC-derived strains correlated with age more strongly than did bone mineral density (BMD) for T11.

Abstract
Osteoporosis (OP) and osteoporotic fractures (OFs) are common multifactorial and heterogenic disorders of increasing incidence. Helicobacter pylori (H.p.) colonizes the stomach approximately in half of the world's population, causes gastroduodenal diseases and is prevalent in numerous extra-digestive diseases known to be associated with OP/OF. The studies regarding relationship between H.p. infection (HPI) and OP/OFs are inconsistent. The current review summarizes the relevant literature on the potential role of HPI in OP, falls and OFs and highlights the reasons for controversies in the publications. In the first section, after a brief overview of HPI biological features, we analyze the studies evaluating the association of HPI and bone status. The second part includes data on the prevalence of OP/OFs in HPI-induced gastroduodenal diseases (peptic ulcer, chronic/atrophic gastritis and cancer) and the effects of acid-suppressive drugs. In the next section, we discuss the possible contribution of HPI-associated extra-digestive diseases and medications to OP/OF, focusing on conditions affecting both bone homeostasis and predisposing to falls. In the last section, we describe clinical implications of accumulated data on HPI as a co-factor of OP/OF and present a feasible five-step algorithm for OP/OF risk assessment and management in regard to HPI, emphasizing the importance of an integrative (but differentiated) holistic approach. Increased awareness about the consequences of HPI linked to OP/OF can aid early detection and management. Further research on the HPI-OP/OF relationship is needed to close current knowledge gaps and improve clinical management of both OP/OF and HPI-related disorders.

Abstract
Several previous studies have suggested a relationship between GERD and RA. However, no study has investigated the bidirectional relationship between GERD and RA. This study aimed to evaluate the causal relationships between rheumatoid arthritis (RA) and gastroesophageal reflux disease (GERD). Participants aged ≥ 20 years old in the Korean Health Insurance Review and Assessment Service-National Sample Cohort from 2002 to 2013 were enrolled. In study I, 132,140 GERD participants were 1:2 matched with 264,280 control I participants. In study II, 6615 RA participants were 1:4 matched with 26,460 control II participants. Both control I and control II groups were matched with their study groups for age, sex, income, and region of residence. The occurrence of RA (study I) and GERD (study II) were followed up in both the study and control groups. The hazard ratios (HRs) of GERD for RA (study I) and of RA for GERD (study II) were analysed using stratified Cox-proportional hazards models. In study I, 0.8% (1,034/132,140) of the GERD group and 0.5% (1,290/264,280) of the control I group had RA (P < 0.001). The GERD group demonstrated a 1.49-fold higher adjusted HR than did the control I group (95% confidence interval (95% CI) = 1.37-1.62, P < 0.001). In study II, 22.5% (1,490/6,615) of the RA group and 15.2% (4,034/26,460) of the control II group had GERD (P < 0.001). The RA group showed a 1.46-fold higher adjusted HR than did the control II group (95% CI = 1.38-1.55, P < 0.001). GERD and RA have bidirectional associations in Korean adult population. Key Points • Several previous studies have suggested a relationship between gastroesophageal reflux disease (GERD) and rheumatoid arthritis (RA). • However, no study has investigated the bidirectional relationship between GERD and RA. • This is the first study to present a bidirectional relationship between GERD and RA. • GERD and RA have bidirectional relations with each other.

Abstract
The introduction of acid inhibition in clinical practice has revolutionized the management of acid-related diseases, leading to the virtual abolition of elective surgery for ulcer disease and relegating antireflux surgery to patients with gastroesophageal reflux disease (GERD) not adequately managed by medical therapy. Proton pump inhibitors (PPIs) are the antisecretory drugs of choice for the treatment of reflux disease. However, these drugs still leave some unmet clinical needs in GERD. PPI-refractoriness is common, and persistent symptoms are observed in up to 40-55% of daily PPI users. Potassium-competitive acid blockers (P-CABs) clearly overcome many of the drawbacks and limitations of PPIs, achieving rapid, potent, and prolonged acid suppression, offering the opportunity to address many of the unmet needs. In recent years, it has been increasingly recognized that impaired mucosal integrity is involved in the pathogenesis of GERD. As a consequence, esophageal mucosal protection has emerged as a new, promising therapeutic avenue. When P-CABS are used as add-on medications to standard treatment, a growing body of evidence suggests a significant additional benefit, especially in the relief of symptoms not responding to PPI therapy. On the contrary, reflux inhibitors are considered a promise unfulfilled, and prokinetic agents should only be used on a case-by-case basis.

Vertebral stiffness measured via tomosynthesis-based digital volume correlation is strongly correlated with reference values from micro-CT-based DVC. Med Eng Phys 2020; 84:169-173. [PMID: 32977915 DOI: 10.1016/j.medengphy.2020.08.008] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2020] [Revised: 07/03/2020] [Accepted: 08/24/2020] [Indexed: 11/21/2022]
Abstract
Digital tomosynthesis (DTS) is a clinically available modality that allows imaging of a patient's spine in supine and standing positions. The purpose of this study was to establish the extent to which vertebral displacement and stiffness derived from DTS-based digital volume correlation (DTS-DVC) are correlated with those from a reference method, i.e., microcomputed tomography-based DVC (μCT-DVC). T11 vertebral bodies from 11 cadaveric donors were DTS imaged twice in a nonloaded state and once under a fixed load level approximating upper body weight. The same vertebrae were µCT imaged in nonloaded and loaded states (40 μm voxel size). Vertebral displacements were calculated at each voxel using DVC with pairs of nonloaded and loaded images, from which endplate-to-endplate axial displacement (DDVC) and vertebral stiffness (SDVC) were calculated. Both DDVC and SDVC demonstrated strong positive correlations between DTS-DVC and μCT-DVC, with correlations being stronger when vertebral displacement was calculated using the median (R2=0.80; p<0.0002 and R2=0.93; p<0.0001, respectively) rather than average displacement (R2=0.63; p<0.004 and R2=0.69; p<0.002, respectively). In conclusion, the demonstrated relationship of DTS-DVC with the μCT standard supports further development of a biomechanics-based clinical assessment of vertebral bone quality using the DTS-DVC technique.

Abstract
STUDY DESIGN Retrospective observational study. OBJECTIVE The study objectives were to: (1) determine radiographically which spinal malalignment parameters predominantly influence the risk of gastroesophageal reflux disease (GERD); (2) evaluate the outcome of GERD 2 years after surgery for adult spinal deformity (ASD); and (3) clarify key factors that influence the improvement of postoperative GERD in ASD. SUMMARY OF BACKGROUND DATA Spinal deformity is reported to be involved in the pathology of GERD. Our previous study found that approximately 50% of patients treated surgically for ASD had GERD symptoms. However, the postoperative progress of GERD and the key factors that influence the improvement of postoperative GERD are largely unknown. METHODS Ninety-two patients with ASD treated with thoracolumbar corrective surgery and followed up for a minimum of 2 years were enrolled. All patients were asked to complete the Frequency Scale for Symptoms of GERD (FSSG) questionnaire preoperatively and at 1 and 2 years after surgery. GERD was diagnosed by FSSG score more than 8 points. Before, and at 1 and 2 years after surgery, full-length lateral radiographs were taken and radiographic parameters were obtained. RESULTS Patients were classified into two groups based on GERD symptoms, with 47 (51.1%) in the GERD+ group. Among parameters assessed, only thoracolumbar kyphosis (TLK) was significantly greater in the GERD+ group than in the GERD- group. The FSSG score improved significantly 1 year after surgery, but no significant difference was found between groups at 2 years. A significant correction loss of TLK was observed 2 years after surgery. There was a significant highly positive correlation between the FSSG score and TLK at 2 years after surgery. CONCLUSION GERD improved with correction of the spinal deformity but significant correction loss of the TLK even within the fusion presumably due to subsidence or proximal junctional kyphosis resulted in a cessation of that improvement over time. LEVEL OF EVIDENCE 3.

Abstract
Lateral approach corpectomy is a useful surgical technique for adult spinal deformity with vertebral deformity. However, in cases with anterior ankylosing over adjacent vertebrae, it is hard to achieve ideal correction without posterior column resection. To minimize surgical invasiveness, we have developed a method for lateral approach corpectomy and reconstruction after anterior longitudinal ligament release (LCRA) in such cases. The aim of the current study is to describe LCRA, and investigate surgical invasiveness, sagittal correction and perioperative complications in this surgery. The subjects were three patients (all female, average age 69.0 years old) with adult spinal deformity with severe fixed kyphosis who underwent LCRA and posterior fixation with pedicle screws. The primary disease was osteoporotic vertebral fracture in all patients. The operative levels were T12 in 2 cases and L2 in 1 case. The operative time and estimated blood loss were 442.3 ± 51.9 min and 875.7 ± 397.5 mL, respectively. Local kyphotic deformity was well corrected from 54.2 ± 4.3° preoperatively to 10.1 ± 3.7° in these surgeries (p < 0.001). There were surgical complications of dural tear and postoperative hemothorax in one case each. These outcomes suggest that LCRA gives good sagittal correction in cases with fixed kyphosis after osteoporotic vertebral fracture, and that this method is a viable surgical option for correction of fixed kyphosis.

Spine J 2020; 20:380-390. [PMID: 31539625 DOI: 10.1016/j.spinee.2019.09.012] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/22/2019] [Revised: 07/13/2019] [Accepted: 09/11/2019] [Indexed: 02/03/2023]
Abstract
BACKGROUND CONTEXT Few studies have described reciprocal changes of pathologic compensatory mechanisms in the setting of spinopelvic fixation using full-body radiograph. PURPOSE To elucidate how sagittal alignment of unfused spinal segments and lower extremities change reciprocally following complex thoracolumbar realignment surgery including fusion to the sacrum in adult spinal deformity. STUDY DESIGN Retrospective cohort. PATIENT SAMPLE Thirty-four patients who underwent fusion from lower thoracic to the sacrum/pelvis and 49 patients with fusion from upper thoracic to the sacrum/pelvis. OUTCOME MEASURES The postoperative sagittal alignment change, and the correlation between the instrumented spinopelvic alignment change and reciprocal changes in unfused spinal segments/lower extremities. MATERIALS/METHODS This study included 34 patients who underwent fusion from lower thoracic to the sacrum/pelvis (LT-P group) and 49 patients with fusion from upper thoracic to the sacrum/pelvis (UT-P group). The postoperative sagittal alignment changes were evaluated after subdividing the two groups according to T1 pelvic angle (TPA) (aligned group: TPA<20 and malaligned group: TPA>20). The correlation between the instrumented spinopelvic alignment change (ΔTPA and ΔLL), reciprocal changes in unfused spinal segments and lower extremities, and the cranial sagittal vertical axis-hip/ankle change (ΔCrSVA-Hip/Ankle) were also analyzed. RESULTS At the baseline in both LT-P and UT-P groups, the patients in the malaligned subgroups showed greater C2-7 lordosis (C2-7L), sacrofemoral angle (SFA), and knee flexion angle (KA) than those in the aligned subgroups. At average 7.1 months postoperatively, these compensatory mechanisms were restored in accordance with instrumented TPA/LL change, especially in the UT-P group. The mid-thoracic alignment changed significantly kyphotic in the LT-P group. ΔTPA and ΔLL linearly correlated with ΔC2-7L, ΔKA, and ΔAA in the malaligned patients. The multivariate regression analysis revealed that change in lower extremity parameters (ΔSFA, ΔKA, and ΔAA) independently impacted ΔCrSVA-Hip/Ankle. CONCLUSION Adequate thoracolumbar realignment surgery results in restoration of the pathologic compensatory mechanisms in the unfused spinal segments and lower extremities, especially in patients fused from upper thoracic spine. A preoperative clinical evaluation of the lower limb joints, as well as a full-body radiographic evaluation, is paramount to achieve optimal global sagittal balance in thoracolumbar realignment surgery.

Abstract
PURPOSE The objective was to identify risk factors for new development of gastroesophageal reflux disease (GERD) 5 years later in a prospective longitudinal cohort study. METHODS A total of 178 subjects (male 72, female 106, mean age 68 years) without GERD in 2013 were examined for GERD in 2018. A Frequency Scale for Symptoms of GERD score ≥ 8 was used for diagnosis of GERD. Body mass index, spinal alignment, muscle strength, physical ability, number of oral drugs per day, sarcopenia, and frailty determined in 2013 and 2018 were compared between the GERD(+) and GERD(-) groups in 2018. Aggravation of lumbar kyphosis and spinal inclination from 2013 to 2018 was defined as a change of ≥ 5° or ≥ 10°, and weakening of back muscle strength as a change of ≥ 10 kg. QOL (SF-36) was also examined. RESULTS Of the 178 subjects, 38 (21%) were diagnosed as GERD(+) in 2018. Sarcopenia in 2018 was significantly related to a GERD(+) status (p < 0.05). The GERD(+) group had significantly higher rates of changes of lumbar kyphosis ≥ 5° (p < 0.005) and ≥ 10° (p < 0.0001), of spinal inclination ≥ 5° (p < 0.0001), and of decreased back muscle strength ≥ 10 kg (p < 0.05). SF-36 were also significantly worse in the GERD(+) group (p < 0.05). CONCLUSIONS This prospective longitudinal study firstly demonstrated that lumbar kyphotic change, aggravation of spinal inclination, decreased back muscle strength, and sarcopenia are significant risk factors for new development of GERD. Management and prevention of these factors may contribute to reduction of GERD symptoms and increased QOL in middle-aged and elderly people.

Abstract
This study aims to evaluate endplate/cortex fracture (ECF)-based method for detecting osteoporotic vertebral fracture (VF) in elderly Chinese population (age ≥ 65 years). The radiographs of 1954 elderly Chinese men (mean: 72.3 years) and 1953 elderly Chinese women (mean: 72.5 years) were evaluated according to Genant's morphometrical vertebral deformity (VD) severity criteria, as well as identified VF according to ECF without necessary requirement of VD. According to ECF, grade-1, -2, and -3 VF prevalence was 1.89%, 1.74%, and 2.25% in men, and 3.33%, 3.07%, and 5.89% in women, respectively. In men and women, 15.7% (35 of 223) and 34.5% (48 of 139) of vertebrae with VD grade-1 deformity were ECF(+, with fracture), respectively. In men and women, 89.7% (35 of 39) and 66.7% (48 of 72) of vertebrae with ECF grade-1 fracture had VD grade-1 deformity. For grade-1 change, ECF(+) subjects tended to have a lower BMD than the VD(+) subjects. In subjects with VD grade-2 deformity, those who were also EC (+) tended to have a lower BMD than those were ECF(-). In all grades, VD(-) and ECF(-) subjects tended to have highest BMD, whereas VD(+) and ECF(+) subjects tended to have lowest BMD. ECF may be more specific for assessing mild VF than the criteria based on vertebral deformity.

Kyphoplasty of Osteoporotic Fractured Vertebrae: A Finite Element Analysis about Two Types of Cement. BIOMED RESEARCH INTERNATIONAL 2019; 2019:9232813. [PMID: 31143778 PMCID: PMC6501275 DOI: 10.1155/2019/9232813] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/13/2019] [Accepted: 04/09/2019] [Indexed: 12/11/2022]
Abstract
If conservative treatment of osteoporotic vertebral compression fractures fails, vertebro- or kyphoplasty is indicated. Usually, polymethylmethacrylate cement (PMMA) is applied coming along with many disadvantageous features. Aluminum-free glass-polyalkenoate cement (GPC) appears to be a benefit alternative material. This study aimed at comparing the mean stress values in human vertebrae after kyphoplasty with PMMA and GPC (IlluminOss™) at hand of a finite element analysis. Three models were created performing kyphoplasty using PMMA or IlluminOss™, respectively, at two native, human lumbar vertebrae (L4) while one remains intact. Finite element analysis was performed using CT-scans of every vertebra. Moreover the PMMA-treated vertebra was used as a model as analyses were executed using material data of PMMA and of GPC. The unimpaired, spongious bone showed potentials of 0.25 MPa maximally. After augmentation stress levels showed fivefold increase, rising from externally to internally, revealing stress peaks at the ventral border of the spinal canal. At central areas of cement 1 MPa is measured in both types of cement. Around these central areas the von Mises stress decreased about 25-50% (0.5-0.75 MPa). If workload of 500 N was applied, the stress appeared to be more centralized at the IlluminOss™-model, similar to the unimpaired. Considering the endplates the GPC model also closely resembles the unimpaired. Comparing the PMMA-treated vertebral body and the GPC-simulation, there is an obvious difference. While the PMMA-treated model showed a central stress peak of 5 MPa, the GPC-simulation of the same vertebral body presents lower stress of 1.2-2.5 MPa. Finite element analysis showed that IlluminOss™ (GPC), used in kyphoplasty of vertebral bodies, creates lower level stress and strain compared to standardly used PMMA, leading to lower stress concentrations on the cranial and caudal vertebral surface especially. GPC appears to own advantageous biological and clinical relevant features.

Abstract
RATIONALE Few comparative studies have evaluated the differences between intravenous alendronate (ALN) and ibandronate (IBN) in patients with osteoporosis. This study was to compare the effects of these 2 drugs on bone mineral density (BMD), bone metabolic markers, and adverse events in patients with osteoporosis. PATIENT CONCERNS Seventy-eight subjects were assigned to the ALN group and 66 to the IBN group. DIAGNOSES The diagnosis of osteoporosis was based on BMD values of the femoral neck or lumbar spine less than -2.5 SD below the reference values. INTERVENTIONS This study was designed as a 52-weeks, prospective, non-randomized study involving a parallel-group comparison between intravenous ALN and intravenous IBN in elderly women with osteoporosis. OUTCOMES The non-switched-IBN subgroup showed significant decrease in serum collagen type I cross-linked telopeptide (NTX) at 6 and 12 months compared with baseline, and the decrease in NTX were significantly greater in the non-switched-IBN subgroup than in the non-swithed-ALN subgroup. BMD in the lumbar spine in the non-switched-IBN subgroup showed a significant increase at 12 months and the increase in BMD were significantly larger than in the non-switched-ALN subgroup. LESSONS Intravenou IBN might result in a significantly greater increase of BMD and decrease in NTX, but it had a higher incidence of adverse drug reactions than ALN.

Abstract
BACKGROUND Helicobacter pylori (H. pylori) infection can induce individual inflammatory and immune reactions which associated with extra-digestive disorders. Our aim is to investigate the association between H. pylori infection and bone mineral density. METHODS This retrospective cross-sectional study was performed by using the data from the health examination database in a medical center of southern Taiwan in 2013. We investigated the relationship between sex, age, body mass index (BMI), waist circumstance, lipid profile, H. pylori infection, the findings of upper gastrointestinal endoscopy and bone mineral density (BMD). Because of nonrandomized assignment and strong confounding effect of age on BMD, the 1:1 propensity score match was applied for age adjustment. The simple and multiple stepwise logistic regression analysis were performed to assess the risk factors of decreased BMD in these well-balanced pairs of participants. RESULTS Of the 867 subjects in final analysis with the mean age of 55.9 ± 11.3 years, 381 (43.9%) subjects had H. pylori infection, and 556 (64.1%) subjects had decreased BMD. In decreased BMD group, the portion of woman was higher than a normal BMD group (37.2% versus 29.6%, P = 0.023), the age was significantly older (59.4 ± 9.8 versus 49.8 ± 11.3, p < 0.001) and BMI was significantly lower (24.7 ± 3.5 versus 25.4 ± 3.7, p = 0.006) than the normal BMD group. The prevalence of H. pylori infection was 39.9% and 46.2% in the normal BMD group and the decreased BMD group respectively (P = 0.071). The multivariate analysis which was used for these possible risk factors showed that only advanced age (OR 1.09, 95% CI 1.08-1.11, P < 0.001), and low BMI (OR 0.91, 95% CI 0.87-0.95, P < 0.001) were independently significantly associated with decreased BMD in this nonrandomized study. In the propensity score-matched participants, the multiple stepwise logistic regression analysis revealed H. pylori infection (OR 1.62, 95% CI 1.12-2.35, P = 0.011) and low BMI (OR 0.92, 95% CI 0.87-0.97, P = 0.001) were independently significantly associated with decreased BMD. CONCLUSIONS H. pylori infection and low BMI were independently significantly associated with decreased BMD in selected propensity score-matched populations after age adjustment.

Abstract
Vertebral fractures commonly occur at the thoracolumbar junction. These fractures can be treated with mild residual deformity in many cases, but are reportedly associated with increased risk of secondary vertebral fractures. In the present study, a three-dimensional (3D) whole spine model was constructed using the finite element method to explore the mechanism of development of compression fractures. The 3D model of the whole spine, from the cervical spine to the pelvis, was constructed from computed tomography (CT) images of an adult male. Using a normal spine model and spine models with compression fractures at the T11, T12 or L1 vertebrae, the distribution of strain was analyzed in the vertebrae after load application. The normal spine model demonstrated greater strain around the thoracolumbar junction and the middle thoracic spine, while the compression fracture models indicated focused strain at the fracture site and adjacent vertebrae. Increased load time resulted in the extension of the strain region up to the middle thoracic spine. The present findings, that secondary vertebral fractures commonly occur around the fracture site, and may also affect the thoracic vertebrae, are consistent with previous clinical and experimental results. These results suggest that follow-up examinations of compression fractures at the thoracolumbar junction should include the thoracic spine and adjacent vertebrae. The current data also demonstrate that models created from CT images can be used for various analyses.

Ohba T, Ebata S, Koyama K, Haro H. Prevalence and key radiographic spinal malalignment parameters that influence the risk for gastroesophageal reflux disease in patients treated surgically for adult spinal deformity. BMC Gastroenterol 2018; 18:8. [PMID: 29320988 PMCID: PMC5763649 DOI: 10.1186/s12876-018-0738-6] [Citation(s) in RCA: 17] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/24/2017] [Accepted: 01/04/2018] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Gastroesophageal reflux disease (GERD) is a factor that has a significant negative impact on the quality of life (QoL). Vertebral fractures and/or spinal malalignment may influence the frequency of GERD. However, the epidemiology and pathology of GERD in patients with adult spinal deformity (ASD) are still largely unknown. To establish the optimal surgical strategy for GERD in patients treated surgically for ASD, we sought to clarify the GERD prevalence, determine radiographically which spinal malalignment parameters influence GERD risk, and evaluate GERD improvement postoperatively. METHODS Seventy-one consecutive patients with ASD who were treated with thoracolumbar corrective surgery and followed up for at least 1 year were enrolled. GERD was diagnosed by a gastroenterologist based on proton pump inhibitor medication response and/or an FSSG score > 8 points. Full-length lateral radiographs in a standing posture and in a supine, fulcrum backward-bending (FBB) position were taken preoperatively and 1 year postoperatively, and radiographic parameters were obtained. Correlations between radiographic parameters and FSSG scores were determined by Pearson's correlation coefficient. Multivariate logistic regression analyses were performed to evaluate the odds ratio (OR) with a 95% confidence interval (95% CI) for potential risk factors for GERD. RESULTS Patients were classified into two groups based on GERD symptoms, with 37 (52%) in the GERD+ group. Thoracolumbar kyphosis (TLK) in the FBB position was significantly more common in the GERD+ versus the GERD- group. Multivariate logistic regression analysis showed that lumbar lordosis (LL) and TLK curve in the FBB position significantly influenced the presence of GERD. Other factors showed no association with GERD. Significant improvements in FSSG scores were noted 1 year postoperatively. However, 20 (28.2%) patients still had GERD symptoms. The postoperative TLK curve was highly significantly correlated with FSSG scores 1 year postsurgery. CONCLUSIONS Of the 71 patients treated surgically for ASD, 37 (52%) had a high frequency of GERD symptoms. An inflexible thoracolumbar curve with increased TLK in the FBB position was significantly associated with GERD symptoms. Despite significant improvements in FSSG scores postoperatively, insufficient correction of TLK might be a risk factor for persistent GERD symptoms.

Abstract
UNLABELLED This study compared spinal alignment, muscular strength, and quality of life (QOL) between women with postmenopausal osteoporosis and healthy volunteers. The results indicated that lower QOL in osteoporosis patients may be associated with increased thoracic kyphosis, reduced lean muscle mass, and generalized muscle weakness. INTRODUCTION Increased spinal kyphosis is common in patients with osteoporosis and negatively impacts quality of life (QOL). Muscular strength is also important for QOL in patients with osteoporosis. However, spinal kyphosis and muscle weakness also occur in healthy individuals with advancing age. The purposes of this study were thus to compare spinal alignment, muscular strength, and QOL between women with postmenopausal osteoporosis and healthy volunteers. METHODS Participants comprised 236 female patients with postmenopausal osteoporosis (mean age, 68.7 years) and 93 healthy volunteer women (mean age, 71.0 years). Body mass index (BMI), angles of spinal kyphosis, back extensor strength, grip strength, and QOL were compared between groups. RESULTS BMI, back extensor strength, and grip strength were significantly higher in the volunteer group than in the osteoporosis group (p < 0.01). Both thoracic kyphosis and lumbar lordosis were significantly greater in the osteoporosis group than in the volunteer group (p < 0.01). With regard to QOL, the 36-Item Short-Form Health Survey (SF-36) subscale scores of role physical, bodily pain, general health, and role emotional were all significantly lower in the osteoporosis group than in the volunteer group (p < 0.05 each). SF-36 physical component summary (PCS) score was significantly lower in the osteoporosis group than in the volunteer group (p < 0.001). SF-36 PCS score correlated positively with thoracic kyphosis and negatively with BMI only in the osteoporosis group (p < 0.05 each). CONCLUSIONS These results indicated that lower QOL in osteoporosis patients may be associated with increased thoracic kyphosis, reduced lean muscle mass, and generalized muscle weakness.

Abstract
Osteoporotic vertebral fracture (OVF) is a worldwide health concern and lacks sufficient basic studies. Suitable animal models should be the foundation for basic study and treatment of OVF. There have been few studies on the development of animal models of osteoporotic vertebral bone defects. OVF models using various animal species should be developed to evaluate the therapeutic strategy in preclinical testing. We developed an OVF model in rats. Rat osteoporosis was induced by ovariectomy (OVX), and 3 months after OVX, a 3 mm diameter hemispheric vertebral bone defect was developed in lumbar vertebra 6 (L6). Sagittal plain X-rays of the rats, their bone quantity, bone microarchitecture, and histomorphology were analyzed: 3 months after OVX, rats showed significantly lower bone quantity, relative bone volume, and total volume bone mineral density. After the vertebral bone defect had developed for 16 weeks, no significant indication of self-healing could be observed from the sagittal plain X-rays, three-dimensional images, and histomorphology. These results indicate that the rat model of osteoporotic vertebral bone defect, induced by OVX and a 3 mm diameter hemispheric vertebral bone defect, can sufficiently mimic OVF patients in clinic and provide a sound basis for subsequent studies.

Abstract
STUDY DESIGN A prospective observational study. OBJECTIVE To evaluate whether scoliosis is a risk factor for gastroesophageal reflux disease (GERD) in elderly patients. SUMMARY OF BACKGROUND DATA Sagittal spinal deformities are reported to cause GERD, but its association with spinal deformity in the coronal plane is not well studied. METHODS We examined 190 patients with spinal disorders (mean age 70.6±8.6 y) who underwent standing whole-spine x-rays in the coronal and sagittal planes. GERD symptoms were assessed by Quest score, with a cutoff of 6 points. The relationship between GERD symptoms and radiographic parameters was evaluated. Right convex coronal curves were given negative values, and left convex curves positive values. Degenerative scoliosis was defined when the thoracolumbar/lumbar Cobb angle had an absolute value >10 degrees. Risk factors for GERD were evaluated with univariate and multivariate logistic regression analyses. RESULTS Of the patients, 126 had degenerative scoliosis at the thoracolumbar/lumbar spine (42 with right and 84 with left convex curve), and 59 had GERD. Multivariate logistic regression analysis revealed that the lumbar Cobb angle was significantly associated with GERD (P<0.05, odds ratio=1.021). When patients were categorized by Cobb angle of the lumbar curve (<-30 degrees, large right convex curve; -30 to +30 degrees, small curve; or >+30 degrees, large left convex curve), a large left convex curve was strongly associated with GERD (P<0.05, odds ratio=10.925). CONCLUSIONS Left thoracolumbar/lumbar curve was a significant risk factor for GERD, and risk increased with a curve >30 degrees. Organ disorders such as GERD should be considered when treating elderly patients with degenerative scoliosis.

Novel Measurement Technique for the Sagittal Vertical Axis and Its Clinical Application in Adult Spinal Deformity. Asian Spine J 2017; 11:190-197.

Abstract
STUDY DESIGN Prospective physical measurement of the sagittal vertical axis (SVA). PURPOSE To evaluate a simple method for measuring SVA by analyzing its relationship with radiographic measurements and clinical appearance. OVERVIEW OF LITERATURE No studies have examined physical measurements using the cranial center of gravity (CCG) in a relaxed standing position. METHODS The physical measurement of the horizontal distance between CCG and spina iliaca posterior superior (CCG-SIPS) was measured using a straight ruler in 252 healthy volunteers and 56 patients with adult spinal deformity. Health-related quality of life (HRQOL) was evaluated using the Oswestry disability index (ODI), and clinical symptoms were assessed according to standing status and the presence of gastroesophageal reflux disease (GERD). RESULTS CCG-SIPS increased with age in the volunteer group and strongly correlated with radiographic SVA in the patient group (r=0.984). Differences increased between CCG-SIPS in patients in the relaxed position and radiographic SVA with an increase in sagittal malalignment (r=0.692, p<0.001). ODI with high sagittal malalignment (CCG-SIPS>120 mm) was significantly larger in the patient group than in the group with low sagittal malalignment (59.9±18.8 vs. 45.1±17.0; p=0.004); these patients (CCG-SIPS>120 mm) needed crutches or walkers for standing. The patient group with GERD had significantly larger sagittal malalignment than the group without GERD (160.3 mm vs. 81.0 mm). CONCLUSIONS The CCG-SIPS correlated with age and strongly reflected radiographic SVA and HRQOL in the patients. Moreover, it reflects a relaxed posture without a backward shift in the radiographic position even in patients with severe sagittal malalignment. The critical limit of CCG-SIPS can be relevant to clinical appearance, including standing assistance (>120 mm) and the existence of GERD (>150 mm). Thus, it will be a useful predictor of true SVA in clinical practice before radiographic evaluation.

Abstract
It has been indicated that proton pump inhibitor (PPI) use is associated with a loss of the anti-fracture efficacy of alendronate (AD). However, there are few prospective studies that have investigated the efficacy of AD on lumbar bone mineral density (BMD) in osteoporotic patients who are using PPIs. Thus, the aim of the present study was to investigate the efficacy of alfacalcidol (AC) and AD on lumbar BMD in osteoporotic patients using PPIs. A prospective, randomized, active control study enrolled such osteoporotic patients (age, ≥50 years). The patients were randomly assigned to receive AC (1 µg/day) or AD (35 mg/week) and were followed up for one year. Patient profiles were maintained, and lumbar BMD, bone-specific alkaline-phosphatase (BAP) and collagen type-I cross-linked N-telopeptide (NTX), upper gastrointestinal endoscopy results, and the frequency scale for the symptoms of gastroesophageal reflux disease (FSSG) were evaluated. Percentage changes in lumbar BMD, NTX, BAP, and change in FSSG score from baseline to the end of one year of treatment were investigated. Sixteen patients were eligible for analysis (eight assigned to receive AC, eight assigned to receive AD). The percentage change in lumbar BMD from baseline to the end of treatment was −0.4±4.0% for the AC group vs. 6.8±6.3% for the AD group (P=0.015). No significant percentage change of BAP and NTX between the two groups was observed. Subsequent to one year of treatment, the FSSG score did not change from the baseline values for either study group, and no new bone fractures or esophagitis were observed in either group of patients. The findings demonstrated that in osteoporotic patients using concomitant PPIs, there was a greater increase in lumbar BMD after one year of treatment with AD compared with AC. However, the number of study subjects was small; thus, further, large prospective studies are required to determine the effect of AD in osteoporotic patients using concomitant PPIs.

Abstract
OBJECTIVE To evaluate the relationship between laryngopharyngeal reflux disease and presence of lumbar kyphosis. STUDY DESIGN A cross-sectional study. METHODS We included 20 patients with lumbar kyphosis and 31 control subjects. A diagnosis of laryngopharyngeal reflux disease and gastroesophageal reflux disease was made if the Reflux Symptom Index score was ≥13 and if the Frequency Scale for the Symptoms of Gastroesophageal Reflux Disease was ≥8, respectively. We compared the prevalence of the two reflux diseases, frequent reflux symptoms, and demographic factors between the two groups. RESULTS There was no significant difference in demographic factors between the two groups. Five (25%) of 20 patients with lumbar kyphosis had a Reflux Symptom Index ≥13 compared with one (3.2%) of 31 controls. Seven (35.0%) of 20 patients had a Frequency Scale for the Symptoms of Gastroesophageal Reflux Disease ≥8 compared with three (9.7%) of 31 controls. A comparison of the prevalence of laryngopharyngeal reflux disease and gastroesophageal reflux disease showed a significant difference between patients with kyphosis and controls (P value = 0.029 and 0.036, respectively). In Reflux Symptom Index, heartburn, hoarseness, and a swallowing problem were significantly frequent symptoms in the kyphosis group compared with the control group. CONCLUSIONS The prevalence of laryngopharyngeal reflux disease and gastroesophageal reflux disease was significantly higher in patients with lumbar kyphosis than in controls. Therefore, otolaryngologists and orthopedic surgeons should be aware that patients with lumbar kyphosis are likely to have gastroesophageal reflux disease and also laryngopharyngeal reflux disease.

Improvement of gastroesophageal reflux disease in Japanese patients with spinal kyphotic deformity who underwent surgical spinal correction. Dig Endosc 2016; 28:50-8. [PMID: 26331612 DOI: 10.1111/den.12543] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/30/2015] [Revised: 08/25/2015] [Accepted: 08/27/2015] [Indexed: 12/11/2022]
Abstract
BACKGROUND AND AIM Spinal kyphotic deformity occasionally results in gastroesophageal reflux disease (GERD). The effects of acid reflux on the esophagus in kyphotic patients are unclear, however, and it is unknown whether acid reflux, endoscopic GERD, and reflux-related symptoms improve following surgical spinal correction in these patients. Herein, we investigated the characteristics of GERD in kyphotic patients and the improvement in GERD following surgical correction. METHODS In 48 patients with severe kyphotic deformity scheduled for surgical spinal correction, we conducted esophagogastroduodenoscopy, 24-h pH monitoring and three questionnaire surveys, including the frequency scale for the symptoms of GERD (FSSG). We repeated these measurements after surgical correction and compared pre- and post-surgery values. RESULTS Of 48 patients, 70.8% [95% CI: 55.9-83.0%, 34/48] had endoscopically evaluated esophageal mucosal injury. Regarding pH before surgery, 64.9% (CI: 47.5-79.8%, 24/37) had abnormal acid reflux (intraesophageal pH < 4 more than 5% of the time). FSSG score was significantly associated with the severity of GERD, and the positive rate was 52.6% (CI: 35.8-69.0%, 20/38). Following surgical correction, esophageal mucosal injury improved endoscopically in 90% of patients, and median total FSSG score significantly decreased from 8 (0-30) to 5 (0-19) (P = 0.005). Regarding pH after surgery, prevalence of abnormal acid reflux decreased from 66.7% (95% CI: 41.0-86.7%) to 33.3% (95% CI: 13.3-59.0%) (P = 0.045). CONCLUSION Surgical spinal correction in kyphosis patients improves not only kyphotic deformity-related disorders but also esophageal mucosal injury, abnormal acid reflux, and reflux-related symptoms.

Abstract
Vertebral fractures are one of the most common fractures associated with skeletal fragility and can cause as much morbidity as hip fractures. However, the epidemiology of vertebral fractures differs from that of osteoporotic fractures at other skeletal sites in important ways, largely because only one quarter to one-third of vertebral fractures are recognized clinically at the time of their occurrence and otherwise require lateral spine imaging to be recognized. This article first reviews the prevalence and incidence of clinical and radiographic vertebral fractures in populations across the globe and secular trends in the incidence of vertebral fracture over time. Next, associations of vertebral fractures with measures of bone mineral density and bone microarchitecture are reviewed followed by associations of vertebral fracture with various textural measures of trabecular bone, including trabecular bone score. Finally, the article reviews clinical risk factors for vertebral fracture and the association of vertebral fractures with morbidity, mortality, and other subsequent adverse health outcomes.

Abstract
It has recently been reported that bisphosphonates are the most common treatment for osteoporotic patients. However, they are many problems, including poor bioavailability and adherence, as well as adverse drug reactions. Therefore, intravenous administration of bisphosphonates has been developed to resolve these problems. In Japan today, alendronate and ibandronate have been approved for intravenous administration, and they have advantages, such as good adherence and better gastrointestinal tolerability, compared to oral administration. We attempted to confirm the effects of administration of intravenous alendronate, which is not inferior to oral administration, for osteoporotic patients in earlier research. 200 consecutive Japanese over 70 years-old postmenopausal women who visited the first author’s orthopedic clinic and had femoral neck or lumbar spine bone mineral density (BMD) values more than 2.5 SD lower than the reference values were randomly enrolled in this study. 100 subjects were recruited for administration of intravenous alendronates because of their poor adherence, no respond of treatment status, and gastrointestinal adverse effects. Furthermore, 10 of these subjects were excluded due to discontinuation, and a total of 90 subjects were eligible for the intravenous group. The remaining 50 patients received oral alendronate. The present study also showed no significant difference between intravenous and oral administration with respect to BMD, biochemical bone turnover markers, and the incidence of fractures. These results show that intravenous administration of alendronate is not inferior to oral alendronate for the treatment of osteoporosis. Therefore, intravenous administration of alendronate can be recommended if patients do not tolerate or adhere to oral bisphosphonates.

Abstract
Background A number of diseases and drugs may influence bone mineral density; however, there are few reports concerning the relationship between lifestyle-related diseases and osteoporosis in Japan as determined by multivariate analysis. The aim of this study was to investigate the risk factors for osteoporosis and whether infection by or eradication of Helicobacter pylori is associated with osteoporosis. Methods Between February 2008 and November 2014, using a cross-sectional study design, we investigated patient profile (age, sex, BMI, alcohol, smoking), H. pylori infection status, comorbidities, internal medicine therapeutic agents (calcium channel blocker, HMG-CoA reductase inhibitors, proton pump inhibitor), serum parameters (Hb, calcium, γGTP), bone turn over markers (bone-specific alkaline phosphatase (BAP) and collagen type I cross-linked N telopeptide (NTX), findings on dual-energy x-ray absorptiometry (DEXA) and upper gastrointestinal endoscopy, and Frequency Scale for the Symptoms of GERD score in consecutive outpatients aged ≥50 years at our hospital. We divided the subjects into an osteoporosis group and a non-osteoporosis group and investigated risk factors for osteoporosis between the two groups by bivariate and multivariate analyses. Results Of the 255 eligible study subjects, 43 (16.9%) had osteoporosis. Bivariate analysis showed that advanced age, female sex, lower body mass index, lower cumulative alcohol intake, lower Brinkman index, H. pylori positivity, lower hemoglobin, bone-specific alkaline phosphatase, lower prevalence of hiatal hernia, and endoscopic gastric mucosal atrophy were related to osteoporosis. Multivariate analysis showed that advanced age (odds ratio [OR] 1.13, 95% confidence interval [CI] 1.07–1.19, P<0.001), female sex (OR 6.27, 95% CI 2.26–17.39, P<0.001), low BMI (OR 0.82, 95% CI 0.72–0.94, P=0.005), H. pylori positivity (OR 3.00, 95% CI 1.31–6.88, P=0.009), and BAP (OR 1.07, 95% CI 1.01–1.14, P=0.035) were related to osteoporosis. Conclusion Advanced age, low BMI, BAP, and H. pylori positivity were risk factors for osteoporosis; however, the success of H. pylori eradication was not a risk factor for osteoporosis in Japan.

Abstract
Vertebral fracture (VFx) is associated with various co-morbidities and increased mortality. In this paper, we have studied the detective value of height loss for VFx using two indices; historical height loss (HHL) which is the difference between the maximal height, and the current height (CH), and CH/knee height (KH) ratio. One-hundred and fifty-one postmenopausal women visiting the outpatient clinic of orthopaedics were studied for their CH, self-reported maximal height, KH, and radiographically diagnosed VFx number(s). VFx was present in 41.1 % of the subjects. Multiple regression analyses revealed that the number of prevalent fractures was a significant predictor of HHL and CH/KH ratio. Receiver operator characteristic curve analysis has shown that for HHL, the area under the curve (AUC) with their 95 %CI in the parentheses was 0.84 (0.77, 0.90), 0.88 (0.83, 0.94), and 0.91 (0.86, 0.96) for ≥ 1, ≥ 2, and ≥ 3 fractures, respectively. For the presence of ≥ 1 VFx, the cut-off value was 4.0 cm (specificity 79 %; sensitivity 79 %). Regarding the CH/KH ratio, AUC was 0.73 (0.65, 0.82), 0.85 (0.78, 0.93), and 0.91 (0.86, 0.96) for ≥ 1, ≥ 2, and ≥ 3 fractures, respectively. For the presence of ≥ 1 VFx, the cut-off value was 3.3 (specificity 47 %; sensitivity 91 %). Both cut-off values for HHL and CH/KH ratio had high negative predictivity across the wide range of theoretical VFx prevalence. Thus, HHL and CH/KH were both good detectors of VFx. Our data would be the basis to determine the cut-off value for the screening or case finding of subjects with VFx.

Abstract
UNLABELLED This paper presents a multi-method research project to develop a conceptual framework for measuring outcomes in studies of osteoporotic kyphosis. The research involved literature research and qualitative interviews among clinicians who treat patients with kyphosis and among patients with the condition. INTRODUCTION Kyphosis due to at least one vertebral compression fracture is prevalent among osteoporotic patients, resulting in well-documented symptoms and impact on functioning and well-being. A three-part study led to development of a conceptual measurement framework for comprehensive assessment of symptoms, impact, and treatment benefit for kyphosis. METHODS A literature-based disease model (DM) was developed and tested with physicians (n = 10) and patients (n = 10), and FDA guidelines were used to develop a final disease model and a conceptual framework. RESULTS The DM included signs, symptoms, causes/triggers, exacerbations, and functional status associated with kyphosis. The DM was largely confirmed, but physicians and patients added several concepts related to impact on functioning, and some concepts were not confirmed and removed from the DM. CONCLUSIONS This study confirms the need for more comprehensive assessment of health outcomes in kyphosis, as most current studies omit key concepts.

Abstract
The aim of this study is to investigate the frequency and clinical features of gastroesophageal reflex disease (GERD) in Parkinson's disease (PD). Consecutively recruited PD patients and controls were questioned about heartburn and GERD with a questionnaire. In PD patients, disease duration and severity, quality of life, and nonmotor symptoms were also examined and then the clinical features of GERD were analyzed. A total of 102 patients and 49 controls were enrolled and 21 patients and 4 controls had heartburn, significantly frequent in PD. The prevalence rate of GERD was 26.5% in PD and the odds ratio was 4.05. Heartburn, bent forward flexion, and wearing-off phenomenon were frequent, and scores of UPDRS, total and part II, PD questionnaire-39, and nonmotor symptom scale were significantly higher in PD patients with GERD than without GERD. Multiple logistic regression analysis revealed statistical significance in UPDRS part II and nonmotor symptom scale. This study suggests that GERD is prevalent in PD. Deterioration of daily living activities and other nonmotor symptoms can imply the presence of GERD. Because clinical symptoms of GERD are usually treatable, the management can improve the patient's quality of life. Increased attention should be given to detect GERD in PD.

Abstract
Gastroesophageal reflux disease (GERD) is common in patients with many chronic diseases, but has not been well recognized in rheumatoid arthritis (RA). We investigated the prevalence of GERD symptoms in 278 outpatients with RA and their association with such clinical factors as age, sex, height, weight, body mass index, medications drugs, and functional status evaluated by the Modified Health Assessment Questionnaire (MHAQ). GERD symptoms were evaluated by Frequency Scale for the Symptoms of GERD (FSSG). The mean FSSG score for all patients was 5.6, and 82 patients were considered to have GERD symptoms (FSSG score ≥8), thus the overall prevalence of GERD symptoms was 29.5%. MHAQ score and height were significantly higher and lower, respectively, and prednisolone usage was significantly more in the patients with GERD symptoms than those without. These three clinical factors were also significantly associated with GERD symptoms by univariate logistic regression. Multivariate logistic regression analysis demonstrated that MHAQ was the only clinical factor related to GERD symptoms. In conclusion, the prevalence of GERD symptoms in RA patients was high and strongly associated with decreased functional status, suggesting that physicians should pay attention to GERD symptoms in RA management, especially for patients with low functional status.

UNLABELLED The purpose of the study was to estimate the cost-effectiveness of balloon kyphoplasty compared to nonsurgical management and vertebroplasty for the treatment of hospitalised osteoporotic vertebral compression fractures in the UK. A cost-effectiveness model was constructed and used for analysis. Balloon kyphoplasty may be cost-effective compared to relevant alternatives. INTRODUCTION The objective of this study was to estimate the cost-effectiveness of balloon kyphoplasty (BKP) for the treatment of patients hospitalised with acute osteoporotic vertebral compression fracture (OVCF) compared to percutaneous vertebroplasty (PVP) and nonsurgical management (NSM) in the UK. METHODS A Markov simulation model was developed to evaluate treatment with BKP, NSM and PVP in patients with symptomatic OVCF. Data on health-related quality of life (HRQoL) with acute OVCF were derived from the FREE and VERTOS II randomised clinical trials (RCTs) and normalised to the NSM arm in the FREE trial. Estimated differences in mortality among the treatments and costs for NSM were obtained from the literature whereas procedure costs for BKP and PVP were obtained from three National Health Service hospitals. It was assumed that BKP and PVP reduced hospital length of stay by 6 days compared to NSM. RESULTS The incremental cost-effectiveness ratio was estimated at Great Britain Pound Sterling (GBP) 2,706 per quality-adjusted life year (QALY) and GBP 15,982 per QALY compared to NSM and PVP, respectively. Sensitivity analysis showed that the cost-effectiveness of BKP vs. NSM was robust when mortality and HRQoL benefits with BKP were varied. The cost-effectiveness of BKP compared to PVP was particularly sensitive to changes in the mortality benefit. CONCLUSION BKP may be a cost-effective strategy for the treatment of patients hospitalised with acute OVCF in the UK compared to NSM and PVP. Additional RCT data on the benefits of BKP and PVP compared to simulated sham surgery and further data on the mortality benefits with BKP compared to NSM and PVP would reduce uncertainty.

Abstract
BACKGROUND AND AIM The Frequency Scale for the Symptoms of Gastroesophageal Reflux Disease (FSSG) is the standard questionnaire used in Japan for the diagnosis of gastroesophageal reflux disease (GERD) and assessment of the response to treatment. We modified the FSSG in order to assess dyspepsia symptoms, and evaluated the modified questionnaire. METHODS We modified the FSSG by adding two questions on interdigestive and postprandial epigastric pain. We then assessed the modified FSSG with 100 new untreated symptomatic patients presenting to hospital and in 200 subjects undergoing health checks. Endoscopic assessment of the esophagogastric junction was performed according to the modified Los Angeles classification with addition of Grade N (normal appearance) and Grade M (minimal change). Endoscopic images were assessed by five experienced endoscopists blinded to the questionnaire results. RESULTS The 100 new patients included 16 with erosive GERD (>Grade A), 12 with peptic ulcer, and two with gastric cancer. Among the 70 patients with no evidence of organic disease, the modified FSSG diagnosed functional dyspepsia (FD) in 41 and non-erosive gastric disease (NERD) in 29. A significant difference was seen in the dyspepsia score between patients with FD and NERD. Subjects with endoscopic GERD undergoing health checks had significantly higher scores for all symptoms, reflux symptoms, and dyspeptic symptoms on the modified FSSG. CONCLUSION The modified FSSG can clearly distinguish FD from NERD, and is useful for the assessment of dyspeptic symptoms.

Abstract
Our understanding of esophageal disease and the foregut has evolved over the past 100 years, especially in recent times. Modern diagnostic technologies and new management paradigms have provided progressive insights into the anatomy, physiology, and normal and abnormal function of the esophagus, as well as improving patient care. Yet, the relationship between the esophagus and its close neighbor, the spine, is rarely discussed and likely underappreciated. Anatomic proximity and intertwined pathophysiology led early investigators to postulate relationships between esophageal disease and spinal abnormalities. More recent studies have illustrated a link between spinal disease and hiatal hernias. Objective radiographic measurements of kyphoscoliosis have correlated with increased hiatal hernia formation. Spinal abnormalities and disease of the esophageal hiatus are becoming more common in our aging population, with each carrying significant risk of morbidity and decreased quality of life. Operative planning and subsequent hiatal hernia repair must be undertaken in the context of these spinal abnormalities. A historical review of past publications related to the subject forms the basis for this publication, thus revealing insight and improving our understanding of the association between spinal abnormalities and hiatal hernias.

Abstract
Purpose The aim of the present conventional observational study was to compare the clinical outcomes of initial non-weight-bearing therapy and conventional relative rest therapy among elderly patients with clinical vertebral fractures. Methods In total, 196 consecutive patients with clinical vertebral fractures (mean age: 78 years) who were hospitalized for treatment between January 1999 and March 2007 were analyzed. Initial non-weight-bearing therapy consisted of complete bed rest allowing rolling on the bed without any weight-bearing to the spine for 2 weeks, followed by rehabilitation wearing a soft brace. The indications for initial non-weight-bearing therapy were vertebral fracture involving the posterior portion of the vertebral body at the thoraco-lumbar spine, mild neurological deficit, instability of the fracture site, severe pain, multiple vertebral fractures arising from trauma, malalignment at the fracture site, and mild spinal canal stenosis caused by the fracture. Patients who met the indication criteria were treated with initial non-weight-bearing therapy (n = 103), while the other patients were treated with conventional relative rest (n = 93). All the patients were uniformly treated with intramuscular elcatonin to relieve pain. The primary endpoint was progression of the vertebral fracture. The secondary endpoints included bony union and subjective back pain. The follow-up period was 12 weeks. Results Compared with the conventional relative rest group, the collapse rate of the anterior and posterior portions of the vertebral body was significantly smaller in the initial non-weight-bearing group. The bony union rate was 100% in the initial non-weight-bearing group and 97% in the conventional relative rest group. The number of patients who experienced back pain was significantly lower in the initial non-weight-bearing group than in the conventional relative rest group. Conclusion These results suggest that initial non-weight-bearing therapy is important for preventing vertebral body collapse and for relieving pain among elderly patients with clinical vertebral fractures.

Influence of lumbar kyphosis and back muscle strength on the symptoms of gastroesophageal reflux disease in middle-aged and elderly people. EUROPEAN SPINE JOURNAL : OFFICIAL PUBLICATION OF THE EUROPEAN SPINE SOCIETY, THE EUROPEAN SPINAL DEFORMITY SOCIETY, AND THE EUROPEAN SECTION OF THE CERVICAL SPINE RESEARCH SOCIETY 2012; 21:2149-57. [PMID: 22370926 PMCID: PMC3481106 DOI: 10.1007/s00586-012-2207-1] [Citation(s) in RCA: 56] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/29/2011] [Revised: 01/06/2012] [Accepted: 02/14/2012] [Indexed: 11/23/2022]
Abstract
Objective The objectives of this study was to clarify the relationship between kyphosis and Gastroesophageal reflux disease (GERD) by evaluation of spinal alignment, obesity, osteoporosis, back muscle strength, intake of oral drugs, and smoking and alcohol history in screening of a community population to determine the factors related to GERD symptoms. Summary of background data GERD increases with age and is estimated to occur in about 30% of people. Risk factors for GERD include aging, male gender, obesity, oral medicines, smoking, and alcohol intake. It has also been suggested that kyphosis may influence the frequency of GERD, but the relationship between kyphosis and GERD is unclear. Subjects and methods We examined 245 subjects (100 males and 145 females; average age 66.7 years old) in a health checkup that included evaluation of sagittal balance and spinal mobility with SpinalMouse®, GERD symptoms using the Frequency Scale for Symptoms of GERD (FSSG) questionnaire, body mass index, osteoporosis, back muscle strength, number of oral drugs taken per day, intake of nonsteroidal anti-inflammatory drugs (NSAIDs), intake of bisphosphonates, and smoking and alcohol intake. Results Multivariate logistic regression analysis including all the variables showed that lumbar lordosis angle, sagittal balance, number of oral drugs taken per day, and back muscle strength had significant effects on the presence of GERD (OR, 1.10, 1.11, 1.09 and 1.03; 95%CI, 1.03–1.17, 1.02–1.20, 1.01–1.18 and 1.01–1.04; p = 0.003, 0.015, 0.031 and 0.038, respectively). The other factors showed no association with GERD. Conclusion This study is the first to show that lumbar kyphosis, poor sagittal balance; increased number of oral drugs taken per day, and decreased back muscle strength are important risk factors for the development of GERD symptoms. Thus, orthopedic surgeons and physicians should pay attention to GERD in elderly patients with spinal deformity.

Abstract
Relationship between lumbar kyphotic deformity and gastroesophageal reflux disease has been indicated in recent years. But it remains unclear whether kyphotic deformity of the lumbar vertebrae affects gastric motility. Healthy young adults (n = 20) were analyzed by recording the electrogastrography (EGG) and heart rate variability (HRV) before and after meal with flexion and neutral postures. Dominant power (DP) and dominant frequency (DF) of EGG and low frequency (LF) and high frequency (HF) of HRV were analyzed in blocks of 10 minutes' duration. In neutral posture, DPs of all postprandial durations were significantly higher than those during fasting in two channels (P < 0.05, P < 0.01). However, in flexion posture, only DP at postprandial 20 (10-20 minutes after eating) in a channel was significantly higher than that during fasting (P < 0.05). DF in neutral posture was significantly higher than that in flexion posture at postprandial 20 in a channel (P < 0.05). The standard deviation of DF at postprandial 10 in flexion posture was significantly higher than that during fasting in a channel (P < 0.05). LF/HF in neural posture was significantly higher than that in flexion posture at postprandial 10 (P < 0.05). These findings suggest that inhibition of stomach myoelectrical activity was induced in the flexion posture in this lumbar kyphotic model, and autonomic activity as assessed by HRV did not accord with that expected from EGG.

Abstract
BACKGROUND Kyphosis is a risk factor for the presence of hiatal hernia, which is a strong predictor of Barrett's esophagus. However, the association between kyphosis and Barrett's esophagus has not yet been clarified. To investigate this relationship, the Cobb angle, a marker of kyphosis, was measured in patients with and without Barrett's esophagus. METHODS From January 2006 to December 2010, 26 patients with long-segment Barrett's esophagus (LSBE) were retrospectively enrolled. As the comparative groups, 100 consecutive patients with short-segment Barrett's esophagus (SSBE) and 100 consecutive control patients without Barrett's esophagus were also enrolled in this study. Cobb angles were measured on lateral chest radiographs, and kyphosis was defined as a Cobb angle of greater than 50°. Kyphosis, along with other patient characteristics, were evaluated as possible predictors for SSBE and LSBE. RESULTS The mean Cobb angles in the non-BE, SSBE, and LSBE groups were 31.6° (95% CIs, 29.3°-33.9°), 34.8° (32.1°-37.4°) and 49.4° (44.9°-53.9°), respectively. Statistically significant differences were found between the LSBE and the other 2 groups (p<0.001). The mean Cobb angles were 33.3°±12.4° and 37.0°±14.1°, respectively in patients without and with hiatal hernia (p=0.039). Predictors for Barrett's esophagus of any length were erosive esophagitis and hiatal hernia. Kyphosis had the highest odds ratio for the presence of LSBE (OR, 1.50; 95% CI, 1.05-1.94; p=0.033). Other predictors were hiatal hernia and the absence of Helicobacter pylori infection. CONCLUSION Kyphosis is a risk factor for the presence of LSBE in Japanese patients.
