Vertebral Hounsfield unit values on computed tomography scan (CT values) have been found to be correlated with bone density measured using dual-energy X-ray absorptiometry. We hypothesized that low preoperative CT values are risk factors for early loss of correction after percutaneous posterior spinal fixation (PPSF). This study aimed to evaluate the usefulness of measuring preoperative CT values. ⋯ CT values can predict progressive loss of correction after PPSF.

Degenerative cervical myelopathy (DCM) is the most common cause of spinal cord (SC) dysfunction. In routine clinical practice, SC changes are well depicted using conventional MRI, especially T2-weighted imaging. However, this modality usually fails to provide satisfactory clinico-radiological correlations. In this context we assessed the potential value of quantitative changes measured with a T1 MP2RAGE sequence. ⋯ T1-MP2RAGE mapping in patients with DCM demonstrated both focal and diffuse cervical SC alteration. It could thus be a biomarker for patients with DCM managed surgically.

To compare long-term care escalation encounters among three care patterns for new episodes of neck pain among Medicare beneficiaries. ⋯ Initial spinal manipulative therapy was associated with a significant reduction in downstream care escalation encounters among Medicare beneficiaries with new episodes of neck pain. Our study contributes to a growing body of evidence supporting the integration of non-pharmacological care strategies for neck pain management.

Residual back pain (RBP) is one of the complications following percutaneous vertebroplasty (PVP) in older people with osteoporotic vertebral compression fractures (OVCFs). The vertebral bone quality (VBQ) score obtained from magnetic resonance imaging (MRI) can be used to evaluate bone quality. The objective of this study aimed to explore the potential relationship between the VBQ score and RBP after PVP. ⋯ The preoperative high VBQ score was an independent risk factor associated with RBP after PVP. Moreover, other risk factors included low BMD, lumbodorsal fascia contusion, and cement distribution. The MRI-VBQ score may serve as a useful tool for assisting in evaluating patients at risk of RBP following PVP.

Hereditary Multiple Osteochondromas (HMO), previously known as Multiple Hereditary Exostoses (MHE), is a genetic disorder characterized by the formation of multiple, benign, exostoses (osteochondromas) growing from the metaphyseal region of long bones as well as from the axial skeleton. Lesions originating from the lumbar spine region are rare, and are most common growing from the posterior element of the vertebrae. HMO associated osteochondromas are difficult to treat due to continuous and incontrollable growth of these lesions and a lifetime risk for malignant transformation. ⋯ We describe a 360-degree surgical resection with application of a 3D printed model, navigation, and mini-invasive techniques. Our report may be useful and inspire spine surgeons to apply similar techniques to treat complex spine lesions.
