Case ReportsImaging findings in spinal subarachnoid hemorrhage in patient with hemophilia A: an unusual cause for back pain.
Back pain and presentation with spinal canal hemorrhage in hemophilia is not common; however, these are significant clinical issues and may lead to significant neurological issues and morbidity. We present an interesting case of severe back pain in a young patient with moderate hemophilia A. Imaging confirmed subarachnoid hemorrhage in the spinal canal without intracranial hemorrhage. ⋯ We also describe the anatomy and imaging features of hemorrhage in the different spinal canal compartments, including the subarachnoid space. Spinal canal hemorrhage in hemophilia is an emergency and serious condition and must be diagnosed and treated promptly. It is important to be aware of the diagnostic features of the spinal canal hemorrhage and carefully assess the spinal canal in hemophiliacs on cross-sectional studies.

Case ReportsDynamic ultrasonographic sign for posterior shoulder dislocation.
Acute posterior shoulder dislocation is rare, and its early diagnosis remains a challenge to the emergency physician. This report describes two cases of acute posterior shoulder dislocation confirmed by bedside ultrasound scan performed by the emergency physician. Bedside ultrasound for diagnosis of posterior shoulder dislocation is accurate, noninvasive, repeatable, convenient, and without ionizing radiation. Dynamic ultrasound sign of posterior shoulder dislocation and using bedside ultrasound for verification of successful reduction of posterior shoulder dislocation are described.

ReviewApplication of imaging guidelines in patients with suspected cervical spine trauma: retrospective analysis and literature review.
Safe and efficient clearance of cervical spine injury in blunt trauma patients has been a controversial topic among health professionals. The increased availability of CT scanners in major trauma centers seems to be a factor that has led to increased number of unnecessary cervical spine imaging using this imaging modality. The objective of this study was to investigate the applicability and efficacy of a pre-test clinical criterion in order to stratify post-blunt trauma victims based on their risk of sustaining cervical spine injury and in turn recommend an appropriate imaging modality accordingly. ⋯ No patients with low-risk injuries were demonstrated to have a significant cervical spine injury. There was a statistically significant greater proportion of acute cervical spine injuries detected in the high-risk group (p value = 0.0024). Hence, using Goergen's diagnostic algorithm could reduce the number of unnecessary cervical spine CT scans ordered, while not compromising the quality of care in post-blunt trauma victims.
