Comparative Study
Vertebral augmentation with a novel Vessel-X bone void filling container system and bioactive bone cement.
Evaluation of a novel, leakage-free vertebroplastic instrumentation by fresh cadaveric studies. ⋯ Vessel-X was comparable to kyphoplasty in restoring the mechanical properties and height of the fractured vertebrae. Interestingly, Vessel-X instrumentation showed considerably less cement leakage and better cement placement in the vertebral body. Therefore, it could be a leakage controllable technique in percutaneous vertebral augmentation.

Case report. ⋯ Although this case is extremely rare, clinicians should be keep in mind that cervical dystonia may carry a risk of atlantoaxial subluxation, potentially progressing to myelopathy. Neurosurgery combined with globus pallidus internus-deep-brain stimulation and atlantoaxial fixation is one treatment option for cervical dystonia with atlantoaxial rotatory subluxation.

Case report. ⋯ Hyperparathyroidism may cause tumoral calcinosis-like lesions in the spine. An early spinal decompression followed with parathyroidectomy leads to remission of symptoms.

Prospective cohort study with 10-year follow-up. ⋯ Radiologic results, patient satisfaction, and mean scores for quality of life and back function were excellent after CD instrumentation for AIS, but a considerable number of patients had treatment for back problems.

Comparative Study
Prevalence of lumbar facet arthrosis and its relationship to age, sex, and race: an anatomic study of cadaveric specimens.
An anatomic, epidemiologic study of facet arthrosis in cadaveric lumbar spines. ⋯ Facet arthrosis is a universal finding in the human lumbar spine. Evidence of arthrosis begins early, with more than one half of adults younger than 30 years demonstrating arthritic changes in the facets. The most common arthritic level appears to be L4-L5. Men have a higher prevalence and degree of facet arthrosis than women.
