ReviewOssification of the Ligaments in the Cervical Spine, Including Ossification of the Anterior Longitudinal Ligament, Ossification of the Posterior Longitudinal Ligament, and Ossification of the Ligamentum Flavum.
Ossification of the posterior longitudinal ligament (OPLL), ossification of the anterior longitudinal ligament (OALL), and ossification of the ligamentum flavum (OLF) sometimes are seen in the same patients, but the exact coexisting frequencies are not clear especially in the cervical region. The most frequent combination is OPLL and OALL. ⋯ All of these ossifying diseases of the cervical spinal ligaments are influenced by dynamic factors of the spinal column. The most frequent levels in the cervical spine affected by OPLL, OALL, and OLF are different because of anatomic differences inherent to each ligament.

Detailed brain imaging studies discover gliomas incidentally before clinical symptoms or signs show. These tumors represent an early stage in the natural history of gliomas. ⋯ Because incidental gliomas are typically smaller and less likely to be in eloquent brain locations, there is a strong case for early surgical intervention to maximize resection and improve outcomes. This article discusses developments in the surgical management of low-grade gliomas.

Trigeminal neuralgia is characterized by severe, episodic pain in the trigeminal nerve distribution. Medical therapy is the first line treatment. ⋯ We review the literature and suggest that microvascular decompression remains the gold standard operative therapy. For patients with recurrent pain or who are poor operative candidates, percutaneous radiofrequency rhizotomy offers the best pain response rates and has the advantage of being able to selectively target affected trigeminal divisions.

Odontoid fractures are the most common cervical fracture type among the elderly population. Several treatment options exist for these patients, ranging from immobilization with a semirigid orthosis to surgical arthrodesis. This report reviews the key points in the management of odontoid fractures in the aged patient, including diagnosis, the various forms of conservative therapies, and the options for surgical intervention.

For over 50 years, clinicians have used hypothermia to manage traumatic brain injury (TBI). In the last two decades numerous trials have assessed whether hypothermia is of benefit in patients. ⋯ Randomized control trials for short-term hypothermia indicate no benefit in outcome after severe TBI, whereas longer-term hypothermia could be of benefit by reducing ICP. This article summarises current evidence and gives recommendations based upon the conclusions.
