Penetrating injury to the superior sagittal sinus by a nail in a 4-year-old child: a case report.

Penetrating head injuries are rare in children, with most injuries being accidental as a result of unsupervised use of sharp objects by young children. We present the case of a 4-year-old boy brought to our emergency department with a nail embedded through a wooden board and into his skull. The nail was determined to be entering the superior sagittal sinus through radiographic imaging. Thus, surgical removal of the nail was determined to be necessary. Inspection revealed a likely through-and-through injury to the sinus, and therefore, because sinus reconstruction was not deemed possible, the sinus was occluded with suture ties both in front and behind the nail before nail removal. Postoperatively, the patient did well and remained neurologically intact. Investigation for possible nonaccidental trauma was conducted. Although most commonly accidental in nature, nonaccidental penetrating traumas have been reported in both pediatric and adult populations. This patient did well after occlusion of his superior sagittal sinus at the coronal suture after penetrating injury by a nail. Penetrating injury in the pediatric population is predominantly thought to be accidental, but a high index of suspicion should be maintained for possible nonaccidental etiology.

When to consider retiring an athlete after sports-related concussion.

The pathophysiology of concussion may lead to a variety of both short- and long-term effects, which may lead to a decision to retire from contact sports. These effects follow a recognizable progression and may cause an athlete to opt out of play at any point along this progression. To elucidate the effect of concussion or mild traumatic brain injury and weigh in on a decision to retire, the treating physician needs to take into account the history, neurologic examination, brain imaging, and neuropsychological testing. In addition, myriad social factors surrounding play must be taken into consideration.

The use of MR-myelography combining flexion and extension imaging in the diagnosis of cervical myelopathy: a case report.

This report describes the use of a non-invasive MR-Myelogram combining flexion and extension views to demonstrate causative factors in cervical myelopathy. Utilizing a new approach to MRI, mimicking an older technique of flexion/extension cervical myelography, we were able to identify the pathology of a patient suffering from progressive cervical myelopathy. We report a patient suffering from progressive multilevel cervical myelopathy due to posterior compression of the spinal cord by an inbuckling ligamentum flavum. Neutral position radiologic assessment failed to reveal any significant spinal cord compression. In this patient, the dynamic MRI and MR-Myelography was critical for demonstrating the posterior compression of the spinal cord by the ligamentum flavum. Flexion and extension MRI images of the cervical spine complemented by non-invasive MR-myelography were obtained. Surgical decompression was indicated based on these additional studies. The use of invasive myelography and in particular, flexion/extension myelography is in decline. MR-myelography combining flexion and extension views can be a useful noninvasive means of studying patients with possible ligamentous hypertrophy and dynamic cord compression.
