“…In our previous study, T1 sagittal angle, together with age and PT, was found to be one of the three primary contributors to maintaining sagittal balance. As pelvic parameters play a role in compensatory mechanisms [ 25 ], finding out the possible factors for T1 sagittal angle might be as equally important as finding out the predictors for the whole sagittal balance. In addition, our previous study [ 12 , 13 ] also found that LL and TK were important contributors to sagittal balance.…”

T1 sagittal angle has been reported to be used as a parameter for assessing sagittal balance and cervical lordosis. However, no study has been performed to explore the relationship between T1 sagittal angle and sagittal balance, and whether T1 sagittal angle could be used for osteotomy guidelines remains unknown. The aim of our study is to explore the relationship between T1 sagittal angle and sagittal balance, determine the predictors for T1 sagittal angle, and determine whether T1 sagittal angle could be used for osteotomy guidelines to restore sagittal balance. Medical records of healthy volunteers in our outpatient clinic from January 2014 to August 2015 were reviewed, and their standing full-spine lateral radiographs were evaluated. Demographic and radiological parameters were collected and analyzed, including age, gender, T1 sagittal angle, maxTK, maxLL, SS, PT, and PI. Correlation coefficients between T1 sagittal angle and other spinopelvic parameters were determined. In addition, multiple regression analysis was performed to establish predictive radiographic parameters for T1 sagittal angle as the primary contributors. A total of 119 healthy volunteers were recruited in our study with a mean age of 34.7 years. It was found that T1 sagittal angle was correlated with maxTK with very good significance (r = 0.697, P<0.001), maxLL with weak significance (r = 0.206, P = 0.024), SS with weak significance (r = 0.237, P = 0.009), PI with very weak significance (r = 0.189, P = 0.039), SVA with moderate significance (r = 0.445, P<0.001), TPA with weak significance (r = 0.207, P = 0.023), and T1SPI with weak significance (r = 0.309, P = 0.001). The result of multiple regression analysis showed that T1 sagittal angle could be predicted by using the following regression equation: T1 sagittal angle = 0.6 * maxTK—0.2 * maxLL + 8. In the healthy population, T1 sagittal angle could be considered as a useful parameter for sagittal balance; however, it could not be thoroughly replaced for SVA. maxTK was the primary contributor to T1 sagittal angle. According to this equation, we could restore sagittal balance by surgically changing thoracic kyphosis and lumbar lordosis, which could serve as a guideline for osteotomy.

“…However, limited studies have investigated the effect of exercises as an intervention for hyperkyphosis on physical function, balance and the quality of life among the elderly, especially elderly men. In most studies, only the effect of corrective training on the severity of hyperkyphosis has been evaluated [9][10][11][12][13]. Thus, the impact of training programs on the complications of hyperkyphosis has received little attention.…”

Objectives The present study investigated the effect of kyphosis correction exercise program on physical function, balance, and the quality of life in older men with hyperkyphosis. Methods & Materials Twenty-four men with kyphosis of ≥50° were randomly assigned into an intervention group (n=12, with Mean±SD age=68.75±2.67 years, Mean±SD height=173.66±3.75 cm, Mean±SD weight=73.5±4.75 kg), and a control group (n=12, with Mean±SD age=69.5±2.64 years, Mean±SD height=174.4±7.78 cm, Mean±SD weight= 75.41±5.21 kg). The intervention group attended the corrective exercises program, consisting of 6 exercises that were conducted in 3 sessions per week for 12 weeks. Thoracic kyphosis was assessed using flexible ruler and measuring distance between T 2-T 12 vertebras. Quality of life, static balance on both the eyes open and eyes closed and physical performance were assessed using 36-item Short Form Health Survey, sharpened Romberg test, and 6-minute walk test, respectively. Analysis of Covariance (ANCOVA) was used to analyze the obtained data, at the significance level of P<0.05. Results The obtained results suggest that kyphosis corrective exercises program have significant positive effects on physical function, balance, and movement confidence in the elderly people (P<0.05). In addition, after implementing 12 weeks of kyphosis corrective exercises, physical pain, physical function/ limitations, public and mental health were significantly improved (P<0.05). While other dimensions of the quality of life, showed no significant changes (P>0.05). Conclusion Based on the study results, kyphosis corrective protocol can improve physical function, balance and the quality of life. It could also reduce the economic burden of the disease, and complications related to aging in older men with kyphosis ≤50°. Therefore, we can recommended this corrective exercise program to improve the quality of life and their satisfaction in the elderly.

“…In osteoporotic patients, the abnormal bone mass can affect the mechanical properties of the bone (23) and may lead to low back pain, disc degeneration or wedge fracture of the vertebral body (45678). Moreover, the decreased bone mass of the cervical vertebrae is closely related to loosening of the spinal surgical implant screws and the artificial inter-vertebral disc substitutes (910).…”

ObjectiveTo investigate the bone mineral density (BMD) of cervical vertebrae in a population-stratified manner and correlate with that of the lumbar vertebrae.Materials and MethodsFive hundred and ninety-eight healthy volunteers (254 males, 344 females), ranging from 20 to 64 years of age, were recruited for volumetric BMD (vBMD) measurements by quantitative computed tomography. Basic information (age, height, weight, waistline, and hipline), and vBMD of the cervical and lumbar vertebrae (C2–7 and L2–4) were recorded. Comparisons among sex, age groups and different levels of vertebrae were analyzed using analysis of variance. Linear regression was performed for relevance of different vertebral levels.ResultsThe vBMD of cervical and lumbar vertebrae was higher in females than males in each age group. The vBMD of the cervical and lumbar vertebrae in males and the vBMD of lumbar vertebrae in females decreased with aging. In each age group, the vBMD of the cervical vertebrae was higher than that of the lumbar vertebrae with gradual decreases from C2 to C7 except for C3; moreover, the vBMD of C6 and C7 was significantly different from that of C2–5. Correlations of vBMD among different cervical vertebrae (females: r = 0.62–0.94; males: r = 0.63–0.94) and lumbar vertebrae (males: r = 0.93–0.98; females: r = 0.82–0.97) were statistically significant at each age group.ConclusionThe present study provided normative data of cervical vertebrae in an age- and sex-stratified manner. Sex differences in vBMD prominently vary with age, which can be helpful to design a more comprehensive pre-operative surgical plan.

Sagittal balance of the spine in patients with osteoporotic vertebral fractures

Abstract: Global spinal balance is abnormal in subjects consulting for osteoporosis, even in subjects without VFs. VFs and age are determinants of abnormal sagittal global balance; however, pelvic parameters play a role in compensatory mechanisms.
