Comparative Study
Are lumbar spine reoperation rates falling with greater use of fusion surgery and new surgical technology?
A retrospective analysis of population-based hospital discharge registry from all nonfederal acute care hospitals in Washington State. ⋯ A higher proportion of fusion procedures and the introduction of new spinal implants between 1993 and 1997 did not reduce reoperation rates. Patients who had lumbar surgery for degenerative disease in the late 1990s were more likely to undergo a repeat operation within 4 years than patients who had surgery in the early 1990s.

Case Reports Comparative Study
How does the ossification area of the posterior longitudinal ligament thicken following cervical laminoplasty?
Retrospective case series. ⋯ Young patients with continuous or mixed-type OPLL and C3 involvement of ossification had a risk for progression in OPLL thickness following surgery. As the increased thickness of ossified lesions directly causes the narrowing of the spinal canal, it is important to pay attention to these risk factors and the increase in ossification before and after cervical laminoplasty in the surgical treatment of patients with OPLL.

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.
