Normal hemostasis provides for balanced interactions between the blood vessel wall, coagulation proteins, and platelets. After vascular injury, primary hemostasis and secondary hemostasis function in a coordinated fashion to stop bleeding. ⋯ Emerging coagulation tests are useful point-of-care assays that guide transfusion therapy and diagnose patients with hyperfibrinolysis. This article provides an overview of hemostasis, a summary of standard coagulation testing and point-of-care tests, and a brief review of coagulation test usefulness in neurosurgery, focusing on studies in patients with traumatic brain injury.

ReviewPathophysiology and Management of Intracranial Hypertension and Tissular Brain Hypoxia After Severe Traumatic Brain Injury: An Integrative Approach.
Monitoring intracranial pressure in comatose patients with severe traumatic brain injury (TBI) is considered necessary by most experts. Acute intracranial hypertension (IHT), when severe and sustained, is a life-threatening complication that demands emergency treatment. ⋯ In such cases, adding other monitoring modalities can alert clinicians when the patient is in a state of energy failure. This article reviews the mechanisms, diagnosis, and treatment of IHT and brain hypoxia after TBI, emphasizing the need to develop a physiologically integrative approach to the management of these complex situations.

Despite being the leading cause of spinal cord dysfunction among adults worldwide, little is known about the natural history of degenerative cervical myelopathy (DCM). There is mounting evidence of the effectiveness of surgery for DCM in halting progression of symptoms, and in fact, in improving neurologic outcomes, functional status, and quality of life. However, surgical decision making relies on a weighing of the risks and benefits of alternative strategies. We reviewed the available literature pertaining to the natural course of DCM and the predictors of outcome of nonoperative approaches.

ReviewEpidemiology and Overview of the Clinical Spectrum of Degenerative Cervical Myelopathy.
Degenerative cervical spondylosis (DCM) is an umbrella term used to describe myelopathy caused by various degenerative changes in the cervical spine. This article outlines the spectrum of DCM and reviews the epidemiology of each factor composing DCM. The uniform term of DCM is expected to elucidate the epidemiology of myelopathy caused by degenerative changes of the cervical spine."

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.
