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.

Case ReportsVertebral artery dissection as an extremely rare cause of spinal epidural hematoma: case report and review of the literature.
To present a patient with a cervico-thoracic ventrally located epidural hematoma caused by dissection and subsequent bleeding of the cervical portion of the vertebral artery. ⋯ Dissection of the cervical portion of the vertebral artery with subsequent perivascular bleeding is not well recognized as a possible cause of a spinal epidural hematoma. Even though this entity and the underlying cause may be rare, we suggest a vigilant search for vertebral artery injury in cases of ventrally located cervical and upper thoracic epidural hematoma.

Case ReportsImaging-documented repeated intratumoral hemorrhage in vestibular schwannoma: a case report.
Intratumoral hemorrhage in vestibular schwannomas is rare. Symptoms often have an acute onset and include headache, nausea, vomiting, vertigo, and depressed consciousness. ⋯ The present report details the case of acute neurological deterioration in a patient with repeated intratumoral hemorrhage inside a vestibular schwannoma with computed tomography and magnetic resonance imaging confirmation. To our knowledge, repeated hemorrhage in vestibular schwannoma with radiological confirmation has not been reported before.

Case ReportsRemoval of a chopstick out of the cavernous sinus, pons, and cerebellar vermis through the superior orbital fissure.
Penetrating non-missile orbito cranial injuries are rare in a civilian pediatric setting. We describe a case of a trans-orbital penetration by a wooden chopstick deep down into the cerebellar vermis detected at neuroradiological examination in a child presenting for head injury. The foreign body was successfully pulled out in one piece surgically.
