Adolescent idiopathic scoliosis (AIS) is a complex three-dimensional (3D) deformity of the spine involving deviations in the frontal plane, modifications of the sagittal profile, and rotations in the transverse plane. Although Lenke classification system is based on 2D radiographs and includes sagittal thoracic and coronal lumbar modifiers, Lenke et al. suggested inclusion of axial thoracic and lumbar modifiers in the analysis. ⋯ Addition of axial plane analysis to conventional coronal and sagittal evaluations in patients with Lenke 1A curves may reveal inherent structural differences that are not apparent in single planar radiographic assessments and may necessitate a different surgical strategy.

Percutaneous kyphoplasty is effective for pain reduction and vertebral height restoration in patients with osteoporotic vertebral fractures. However, in cases of severely collapsed fractures involving the loss of more than 70% of the vertebral height, kyphoplasty is technically difficult to perform and the outcomes remain unknown. ⋯ In patients with an anterior vertebral compression ratio more than 70% because of osteoporotic vertebral fracture, although the anterior height and kyphotic angle were significantly lower than those of patients with an anterior vertebral compression ratio of 30% to 50%, kyphoplasty significantly improved the degree of pain, restored the anterior vertebral height, and maintained the kyphotic angle. Therefore, kyphoplasty can be a useful approach in patients with an anterior vertebral compression ratio more than 70%.

The incidence and relevant risk of ischemic stroke after cervical spine trauma remain unknown. ⋯ This analysis revealed that ischemic stroke after cervical spine injury was not uncommon and was associated with increased mortality and morbidity. Occurrence of ischemic stroke was significantly associated with age, comorbidities such as diabetes, and consciousness level at admission, but not with the type of spine injury.

Sagittal standing posture is associated with musculoskeletal symptoms and quality of life. However, the frequency and determinants of suboptimal sagittal alignment outside the clinical context remain to be clarified. ⋯ Higher BMI and central obesity were important potential determinants of nonneutral posture among adults from the general population. Future research should investigate the potential effectiveness of overweight prevention and management in avoiding sagittal misalignment conditions.

Epidural steroid injections (ESIs) have been used for a number of years in the treatment of radicular pain caused by nerve root impingement or stenosis after failed conservative treatments with oral medications, physical therapy, and lifestyle modifications. ⋯ Predictive tools for ESI outcomes, such as nerve root compression grading and inflammatory markers, particularly, elevated IFN-γ from epidural lavage fluid, seem promising in the future. At this time, future research is needed with a larger sample size, broader spectrum of patients, and a more defined system of outcome measurements at standardized follow-up periods before practice recommendations can be made.
