Comparative Study
Comparative study of spinopelvic sagittal alignment between patients with and without degenerative spondylolisthesis.
To date, few studies have focused on spinopelvic sagittal alignment as a predisposing factor for the development of degenerative spondylolisthesis (DS). The objectives of this study were to compare differences in spinopelvic sagittal alignment between patients with or without DS and to elucidate factors related to spinopelvic sagittal alignment. ⋯ Greater PI may lead to the development and the progression of vertebral slip. Different compensatory mechanisms may contribute to the maintenance of spinopelvic sagittal alignment in DS and non-DS patients.

Clinical Trial
Minimally invasive transforaminal lumber interbody fusion and degenerative lumbar spine disease.
The purpose of this study was to assess the clinical and radiological outcomes of minimally invasive transforaminal lumbar interbody fusion (MI-TLIF) surgery for degenerative lumbar spine disease. ⋯ MI-TLIF offers patients a safe and effective surgical treatment option to treat degenerative lumbar spine disease.

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. 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. ⋯ 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.

From a clinical point of view, knowledge of customary standing positions among healthy young adolescents is of primary importance. The purpose of this study was to document the correlations between sagittal standing posture parameters in a pre-peak height velocity (pre-PHV) cohort. ⋯ Although the correlation schemes do not imply a causal relationship, the proposed postural model allows conjecture about standing posture to be organized slightly differently in pre-PHV boys and girls. Whereas the standing posture in pre-PHV boys might be organized predominantly according to an ascending mode, bottom-up and top-down organizations appear to coexist in pre-PHV girls.

'Low back pain' (LBP) is a prevalent condition with a majority showing no specific organic pathology. Distinguishing 'secondary gain motives (SGM)' from organic causes is imperative in clinical practice. We describe here, three new tests-resistive straight leg raise test (rSLRT), resistive forward bend test (rFBT) and heel compression test (HCT) to help differentiate patients with 'SGM' from those without. We conducted a prospective study to validate the above tests in predicting non-organic causes as a reason for LBP. ⋯ rSLRT, rFBT and HCT (NK triad) are highly practical tests which strongly predict SGM status in patients.
