Peripheral causes of foot drop are well recognized. However, causes stemming from the central nervous system represent rare, important, and underappreciated differential etiologies. ⋯ Central causes, although rare, need to be considered in the differential diagnosis of foot drop. Central causative lesions usually occur at locations where pyramidal tract connections are condensed and specific and the function is somatotopically organized. These cases confirm that good results can be achieved when correctable central causes of foot drop are recognized.

To perform an evidence-based review of the literature on neuroimaging techniques utilized in spinal cord injury clinical practice and research. ⋯ MRI should be used as the imaging modality of choice for evaluation of the spinal cord after injury. CT and plain radiography should be used to assess the bony anatomy of the spine in patients with SCI. MRI may be used to identify the location of spinal cord injury. MRI may be used to demonstrate the degree of spinal cord compression after SCI. MRI findings of parenchymal hemorrhage/ contusion, edema, and spinal cord disruption in acute and subacute SCI may contribute to the understanding of severity of injury and prognosis for neurological improvement. MRI-Diffusion Weighted Imaging may be useful in quantifying the extent of axonal loss after spinal cord injury. Functional MRI may be useful in measuring the anatomic functional/metabolic correlates of sensory-motor activities in persons with SCI. MR Spectroscopy may be used to measure the biochemical characteristics of the brain and spinal cord following SCI. Intraoperative Spinal Sonography may be used to identify spinal and spinal cord anatomy and gross pathology during surgical procedures. Further research in these areas is warranted to improve the strength of evidence supporting the use of neuroimaging modalities. Positron Emission Tomography may be used to assess metabolic activity of CNS tissue (brain and spinal cord) in patients with SCI.

Review Case Reports
Extensive postoperative epidural hematoma after full anticoagulation: case report and review of the literature.
A 67-year-old man with degenerative lumbar spinal stenosis and a medical history significant for coronary artery disease underwent routine lumbar surgical decompression. The objective of this study was to report a case of postoperative epidural hematoma associated with the use of emergent anticoagulation, including the dangers associated with spinal decompression and early postoperative anticoagulation. ⋯ Full anticoagulation should be avoided in the early postoperative period. In cases requiring early vigorous anticoagulation, patients should be closely monitored for changes in neurologic status. Combined cervical, thoracic, and lumbar laminectomy, without instrumentation or fusion, is an acceptable treatment option.

Pressure ulcers are a serious complication for people with spinal cord injury (SCI). The Consortium for Spinal Cord Medicine (CSCM) published clinical practice guidelines (CPGs) that provided guidance for pressure ulcer prevention and treatment after SCI. The aim of this study was to assess providers' perceptions for each of the 32 CPG recommendations regarding their agreement with CPGs, degree of CPG implementation, and CPG implementation barriers and facilitators. ⋯ Although generally SCI physicians and nurses agreed with the CPG recommendations as written, they did not feel these recommendations were fully implemented in their respective clinical settings. The focus groups identified multiple barriers to the implementation of the CPGs and suggested several facilitators/solutions to improve implementation of these guidelines in SCI. Participants identified organizational factors and the lack of knowledge as the most substantial systems/issues that created barriers to CPG implementation.

Spinal epidural lipomatosis is the excessive deposition of unencapsulated fat in the epidural space. This is a rare disorder often associated with high levels of endogenous steroids or the administration of exogenous steroids. ⋯ Spinal epidural lipomatosis is a rare side effect of chronic steroid therapy that may occur with relatively short-term, low-dose regimens. In patients with congenital vertebral anomalies, spinal fat deposition may worsen the neurological status in an already compromised cord. Discontinuation of steroid therapy is beneficial; some patients may require surgical intervention for decompression.
