Fluorine-18 fluorodeoxyglucose positron emission tomography findings in spondylodiscitis: preliminary results.
Nuclear medicine procedures can be helpful in diagnosing spine infections. The purpose of the study was to evaluate the findings of positron emission tomography with fluorine-18 fluorodeoxyglucose (FGD-PET) in the detection of spondylodiscitis. We performed FDG-PET in 16 patients with suspected spondylodiscitis. ⋯ The PET scans depicted the paravertebral soft tissue involvement in cases of spondylodiscitis. Our first results showed that FDG-PET is a very sensitive imaging procedure in the detection of spondylodiscitis. Compared to other nuclear medicine procedures, PET enables a rapid imaging with acceptable radiation dose and high spatial resolution.

Randomized Controlled Trial Clinical Trial
The effect of transpedicular intracorporeal grafting in the treatment of thoracolumbar burst fractures on canal remodeling.
Short-segment posterior instrumentation for the treatment of thoracolumbar burst fractures has been reported with a high rate of failure. Transpedicular intracorporeal grafting in combination with short-segment instrumentation has been offered as an alternative to prevent failure. However, concern still remains about the potential complication of further canal narrowing or failure of remodeling with this technique. ⋯ Spinal canal narrowing was 38.5+/-18.2% at presentation, 22.1+/-19.8% postoperatively, and it further improved to -2.5+/-16.7% at follow-up, similar for both groups. Our results demonstrate that transpedicular intracorporeal grafting in the treatment of burst fractures does not have a detectable effect on the rate of reconstruction of the canal area or on remodeling. Spinal canal remodeling was observed to occur in all patients regardless of grafting.

Atlantooccipital dislocation (AOD) is a rare and usually fatal injury. In the current study, the authors reported an extremely rare case of posterior AOD with Jefferson fracture and fracture-dislocation of C6-C7. ⋯ To our knowledge, this is the first report of posterior AOD with two other non-contiguous cervical spine injuries. A high index of suspicion and careful examination of the upper cervical spine should be considered as the key to the diagnosis of AOD in cases that involve multiple or lower cervical spine injuries.

This paper examines the following speculative hypothesis: "that in some patients with scoliosis there is disproportionate neuro-osseous growth--the longitudinal growth of the spinal cord fails to keep pace with the growth of the vertebral column and, as a consequence, the spine buckles into a scoliosis deformity". A literature review of the morphology and neurology of scoliosis does not deny the hypothesis. Several mechanisms are suggested as to why the spinal cord growth could become uncoupled from osseous growth.

Capillary haemangioma is a benign tumour frequently encountered in the skin and other soft tissues. Histologically, these vascular lesions are characterised by nodules of capillary-sized vessels lined by flattened endothelium, each of which is subserved by a feeding vessel. Capillary haemangioma of the central and peripheral nervous system is extremely rare. ⋯ Complete resection is the treatment of choice, and during surgery the vascular tumour is usually found encapsulated and sharply bordered from the surrounding parenchyma of the spinal cord and affected nerve roots. In the present account we give an overview of the clinical features, neuroradiological findings, therapeutic options and histopathological differential diagnostic aspects of spinal intradural capillary haemangioma. In general, vascular lesions of this entity are preoperatively misdiagnosed as neoplasms, and a higher level of clinical and radiological suspicion may avoid surgical overtreatment of these benign tumours.
