Background: Center of pressure (CoP) trajectory is one of the gait parameters that is widely used for clinical assessments. Moreover, the CoP trajectory could be adversely affected by anatomic and mechanical factors that involve foot function, which was shown to be correlated with musculoskeletal diseases. The aim of this study is to compare angle-associated parameters of gait in patients with different lumbar spinal disorders. Methods: The subjects suffered from the same levels of spine impairment, including patients with lumbar spinal stenosis (LSS) and lumbar intervertebral disc degeneration (LIDD) were recruited in this study. The spatio-temporal angular parameters associated with the CoP of the subjects during their gait were collected and examined. The measurements were used to calculate the CoP angle and symmetry angle (SA). Then the butterfly diagram (BD) intersection angle was introduced as a new potential parameter in gait assessment. Results: The results of the current study showed that CoPs and SAs did not vary between the two groups (P > 0.05). The BD intersection angle, however, indicated some variations between patients with LSS and LIDD (P < 0.05). Conclusion: While the results showed that CoP angles and SAs did not differ between the LSS and LIDD groups, it is hypothesized that such disorders that affect the gait could be reflected in the BD intersection angle. Therefore, the BD intersection angle is suggested as a clinical indicator in clarifying patients with lumbar spinal disorders.

Purpose The aim of this study was to evaluate the association between vertebral endplate morphology and the degree of lumbar intervertebral disc degeneration via magnetic resonance imaging (MRI). Methods In total, 150 patients who met the inclusion criteria and were 20–60 years of age were retrospectively evaluated. Patients were evaluated for the presence of intervertebral disc degeneration or herniation, and the degree of degeneration was assessed at all lumbar levels. Vertebral endplate morphology was evaluated based on the endplate sagittal diameter, endplate sagittal concave angle (ECA), and endplate sagittal concave depth (ECD) on sagittal MRI. The association between intervertebral disc degeneration or herniation and endplate morphological measurements was analysed. Results In MRI, superior endplates ( ie, inferior endplates of the superior vertebra) were concave and inferior endplates ( ie, superior endplates of the inferior vertebra) were flat at all disc levels. A decrease in ECD and an increase in ECA were detected at all lumbar levels as disc degeneration increased ( P < .05). At the L4-L5 and L5-S1 levels, a decrease in ECD and an increase in ECA were detected in the group with herniated lumbar discs ( P < .05). There was no association between lumbar disc degeneration or herniation and endplate sagittal diameter at lumbar intervertebral levels ( P > .05). At all levels, ECD of women was significantly lesser than that of men and ECA of women was significantly greater than that of men ( P < .05). Conclusions There is an association between vertebral endplate morphology and lumbar intervertebral disc degeneration. Vertebral endplates at the degenerated disc level become flat; the severity of this flattening is correlated with the degree of disc degeneration.

Background: The symptom severity of back pain/leg pain is not correlated with the severity of degenerative changes and canal stenosis in lumbar stenosis. Considering the individual pain sensitivity might play an important role in pain perception, this discordance between the radiologic findings and clinical symptoms in degenerative lumbar stenosis might originate from the individual difference of pain sensitivity for back pain and/or leg pain. Objective: To determine the relationship among the clinical symptoms, radiologic findings, and the individual pain sensitivity in the patients with degenerative lumbar spinal stenosis. Study Design: Retrospective analysis of prospectively collected data. Setting: A spine center in the department of orthopedic surgery. Methods: In 94 patients who had chronic back pain and/or leg pain caused by degenerative lumbar spinal stenosis, a medical history, a physical examination, and completion of a series of questionnaires, including pain sensitivity questionnaire (PSQ) [total PSQ and PSQ-minor], Oswestry Disability Index (ODI), Visual Analog Pain Scale (VAS) for back pain, and Short Form36 (SF-36) were recorded on the first visit. Radiologic analysis was performed using the MRI findings. The grading of canal stenosis was based on the method by Schizas, and the degree of disc degeneration was graded from T2-weighted images with the Pfirrmann classification. The correlations among variables were statistically analyzed. Results: Total PSQ and PSQ-minor were not dependent on the grade of canal stenosis after gender adjustment. VAS for leg pain and back pain was highly associated with the total PSQ and the PSQ-minor. Total PSQ and PSQ-minor were also significantly associated with ODI. Among SF36 scales, the PSQ minor had significant correlations with SF-36 such as bodily pain (BP), Roleemotional (RE), and Mental Component Summary (MCS) after control of confounding variables such as body mass index (BMI), age, and the grade of canal stenosis/disc degeneration. Total PSQ was significantly associated with the SF-36 RP, BP, and RE. Furthermore, after adjustment for gender and pain sensitivity, there was no significant association between the grade of canal stenosis and VAS for back pain/leg pain and ODI, and no correlation was found between the grade of disc degeneration and VAS for back pain/leg pain and ODI, either. Limitations: The multiple lesions of canal stenosis and/or disc degeneration and the grade of facet degeneration were not considered as a variable. Conclusion: The current study suggests that the pain sensitivity could be a determining factor for symptom severity in the degenerative spinal disease. Key words: Pain sensitivity, pain sensitivity questionnaire, lumbar spinal stenosis, visual analog pain scale, Oswestry disability index, Short Form-36

Objective. Angiopoietin-like protein 4 (ANGPTL4), encoding a glycosylated secreted protein, has been reported to be closely related to many kinds of diseases, including diabetes, tumor, and some musculoskeletal pathologies, such as rheumatoid arthritis, osteoarthritis, and osteoporosis. The aim of the current study is to investigate the role of ANGPTL4 in intervertebral disc degeneration and analyze the association of ANGPTL4 expression with Pfirrmann grades. Methods. A total of 162 nucleus pulposus tissues were collected from lumbar intervertebral disc herniation patients undergoing interforaminal endoscopic surgery. Real-time quantitative PCR and western blot were performed to determine the mRNA and protein expression of ANGPTL4 in nucleus pulposus samples. Statistical analysis was performed to analyze the association of ANGPTL4 expression with Pfirrmann grades. Results. Based on the clinical data of 162 patients, results showed that Pfirrmann grades were significantly associated with patients’ age ( r = 0.162 , P = 0.047 ) and were not significantly associated with patients’ gender ( P > 0.05 ). RT-qPCR and western blot results showed that the mRNA ( r = 0.287 , P < 0.05 ) and protein ( r = 0.356 , P < 0.05 ) expressions of ANGPTL4 were both closely associated with Pfirrmann grades. The expression of ANGPTL4 was remarkably increased in the groups of high IVDD Pfirrmann grades. Conclusion. The results demonstrated that ANGPTL4 expression was positively associated with the Pfirrmann grades and the severity of intervertebral disc degeneration. ANGPTL4 may be served as a candidate biomarker for intervertebral disc degeneration.
