Review Case ReportsRecovery from paraplegia after the treatment of spinal dural arteriovenous fistula: case report and review of the literature.
Spinal dural arteriovenous fistula (SDAVF) is a rare and enigmatic disease. Functional outcome is particularly uncertain for the small group of patients that are unable to stand at the time of diagnosis (grade 5 gait disturbance on the Aminoff-Logue scale, ALS). The objective of this study is to examine the final functional outcome of patients with SDAVF in grade 5 gait ALS before treatment. ⋯ Interruption of SDAVF in paraplegic patients may improve the final functional gait outcome in some cases. No complete recovery (grade 0 gait ALS) was achieved after treatment. Micturition disturbances had a worse prognosis than motor deficits.

Clinical TrialFocal cerebral oxygenation and neurological outcome with or without brain tissue oxygen-guided therapy in patients with traumatic brain injury.
In patients with severe traumatic brain injury (TBI), the depth and duration of cerebral hypoxia are independent predictors of outcome. This study aimed to evaluate the efficacy of brain oxygen-guided therapy in improving cerebral oxygenation and neurological outcome in severe TBI patients. ⋯ In TBI patients, brain tissue oxygen-guided therapy is associated with decreased duration of episodes of cerebral hypoxia. Larger studies are indicated to determine the effects of this therapy on neurological outcome.

Cervical spondylodiscitis is a quite rare finding regarding the number and the common location of spinal abscesses in the lumbar region. While in thoracic and lumbar discitis, single-step surgery with neural decompression, disc space evacuation, and subsequent fusion is well known, there is no such report in cervical discitis. Here the authors present their experience with ventral polyetherketone (PEEK) cage fusion in cervical spondylodiscitis in a single-step procedure. ⋯ In all, abscess drainage and ventral fusion with PEEK-cage disc replacement in one single setting was proven to be a successful treatment option in cervical discitis and spinal epidural abscess.

Treatment of cervical OPLL by cervical anterior fusion using autologous vertebral bone grafts.
In anterior fusion, we use autologous bone grafts from cervical vertebral bodies and bioabsorptive screws to prevent graft extrusion (Williams-Isu method). We report the application of and indication for the Williams-Isu method for OPLL and present our clinical and radiological results. ⋯ The Williams-Isu method is useful for treating not only cervical spondylosis but also cervical segmental OPLL at one or two levels.

Simple identification of the third segment of the extracranial vertebral artery by extreme lateral inferior transcondylar-transtubercular exposure (ELITE).
The exposure of the third segment of the extracranial vertebral artery (V3) is an important step in the extreme lateral inferior transcondylar-transtubercular exposure (ELITE) approach. The muscular suboccipital triangle provides one of the landmarks to identify the V3 segment; however, identification of this triangle and dissection of the V3 segment is not always straightforward in the actual surgery. Blind dissection below the level of the foramen magnum can lead to vertebral artery injury. While the surgeon may be able to readily define the V3 segment of the vertebral artery by feeling its pulse, it is important to have a safe systematic approach to finding the V3 segment when the vessel is illusive. We propose a simple method to identify the V3 segment avoiding accidental injury of the vertebral artery. ⋯ Identification of the V3 segment of the vertebral artery by systematically detecting the four anatomical points defined above is simple and much safer than a direct dissection below the foramen magnum.
