Review
Neurological impairment in a patient with concurrent cervical disc herniation and POEMS syndrome.
POEMS syndrome is a rare clonal plasma cell disease characterized by polyneuropathy, organomegaly, endocrinopathy, M protein, and skin changes. We report a rare case of neurological impairment in patients with concurrent cervical disc herniation and POEMS syndrome. ⋯ Patients presenting with cervical spondylopathy and non-typical neurological signs and symptoms or other systemic problems should be evaluated for the presence of concurrent disease and ruled out differential diagnoses.

Degenerative spondylolisthesis (DS) is a degenerative condition of the spine which, unlike others, is more common in a female population. Previous studies have highlighted possible causative factors such as facet tropism and pregnancy as reasons for this. This study sets out to assess the possible link between abdominal musculature and DS. ⋯ This study highlights the important role that the abdominal musculature plays in stabilization of the spine and highlights its potential role as a factor in the development of DS.

Observational Study
Prediction of brace effect in scoliotic patients: blinded evaluation of a novel brace simulator-an observational cross-sectional study.
Bracing is the most commonly used treatment for scoliosis. But braces remain predominantly "handcrafted." Our objective was to create a novel brace simulator using a high-fidelity 3D "avatar" of the patient's trunk. ⋯ Incorporating high-fidelity copy of the entire 3D shape of the patient's trunk and multiple 3D-reconstructed bony images into an anatomical reference avatar resulted in moderate-to-good prediction of brace effect in three quarters of patients.

For spine curvatures with Cobb angles > 100°, curve classification and characterization become more difficult with conventional radiographs. 3-D computerized axial tomography scans add relevant information to categorize and describe a new classification to aid preoperative assessment in communication and patient evaluation. The purpose of this study is to describe a radiographic classification system of curves exceeding 100°. ⋯ Our study describes a novel method of classifying severe spinal curvatures exceeding 100° using erect AP/lateral radiographs and 3-D CT reconstructive images. We hope that the descriptive analysis and classification will expand our understanding of these complex deformities. These slides can be retrieved under Electronic Supplementary Material.

Vertebral involvement is found in a high percentage of multiple myeloma (MM) patients, often requiring multilevel surgical treatment to reduce pain and disability and to receive prompt access to oncological care. We describe the clinical use of washout technique for multilevel vertebroplasty in MM patients with diffuse spinal involvement. The aim of this technique is to reduce the risk of pulmonary fat embolism after cement injection and possibly to increment the amount of cement and treated levels in one surgical stage. ⋯ Multilevel vertebroplasty in MM patients with diffuse spinal involvement carries the advantages of reducing pain, avoid repeated surgeries and faster return to oncological regimen. Cardiovascular complications, including pulmonary embolism, are rare but can have fatal consequences. It is mainly due to bone marrow mobilization during cement injection and the risk increases with the amount of cement injected and the number of treated levels. Despite multilevel treatment at the same stage, we did not observe any significant complication in our series. Further studies are needed to confirm the preliminary results of this technique.
