Lumbosacral transitional vertebrae (LSTV) often have nearthrosis between the L5 transverse processes and the sacral ala; this causes the formation of new bone and synovial-like tissue, which can entrap L5 nerve root. The present study aimed to examine the role of nearthrosis in L5 nerve root compression in patients with LSTV. ⋯ L5 nerve root was compressed by nearthrosis in 64% of symptomatic patients with LSTV; this region should be carefully assessed in all symptomatic patients with LSTV.

Review
The prevalence and clinical characteristics of thoracic spinal stenosis: a systematic review.
Thoracic spinal stenosis (TSS) is a rare disease secondary to multiple pathological changes that differ in prevalence and clinical characteristics. The epidemiological characteristics of these pathologies are largely unknown due to the limited case samples and regional differences. Therefore, a systematic review was conducted to elucidate the prevalence and clinical characteristics of TSS. ⋯ There are significant differences in the age, sex and segment distribution characteristics of different pathologies leading to TSS. Tandem spinal stenosis is not uncommon and should be considered when diagnosing TSS. Our findings provide new insights into the prevalence and clinical characteristics of TSS and can help reduce misdiagnosis.

Meta Analysis
Meta-analysis of the validity and reliability of rasterstereographic measurements of spinal posture.
We provide a meta-analysis for clinicians and researchers regarding reliability and validity of rasterstereographic measurement of the spinal posture. ⋯ The first meta-analysis on reliability and validity of rasterstereography shows satisfactory results. Rasterstereography thus presents a reliable and valid alternative to classic radiological imaging technique to assess and evaluate spinal posture in patients with spinal pathologies. Further studies are needed, focusing on the measurement properties of both static and dynamic rasterstereographic measurements.

In this prospective study, we aim to determine surgical outcomes in patients with lumbar spinal stenosis (LSS) 10 years after surgery. ⋯ This study reports the clinical course of pain, disability, and walking distance after LSS surgery with the 10-year follow-up. Based on our study results, patients with LSS could expect to have positive effects of their back surgery up to 10 years. However, minor worsening in pain and disability may occur and one-fourth of the patients may need a reoperation during the 10-year follow-up period.

Coronal malalignment (CM) causes pain, impairment of function and cosmetic problems for adult spinal deformity (ASD) patients in addition to sagittal malalignment. Certain types of CM are at risk of insufficient re-alignment after correction. However, CM has received minimal attention in the literature compared to sagittal malalignment. The purpose was to establish reliability for our recently published classification system of CM in ASD among spine surgeons. ⋯ Adequate intra- and inter-rater reliability was shown in the Obeid-CM classification with reference to full spine anteroposterior and lateral radiographs. While side bending radiographs did not improve the classification reliability, they contributed to a better understanding in certain cases. Surgeons should consider both the sagittal and coronal planes, and this system may allow better surgical decision making for CM.
