RESUMEN
¼: Traumatic knee dislocations are complex injuries that can be associated with compromise of the neurovascular structures about the knee. ¼: Various classification systems for knee dislocations exist in the literature but should be used with caution as a prognostic tool because many knee dislocations fit into more than 1 category. ¼: Special populations of knee dislocations, such as obese patients and high-velocity mechanism injuries, require additional caution during the initial evaluation for possible vascular injuries.

We hypothesize that a transient exertion-related carotid (TERC) murmur flow murmur similar in nature to a "bruit" heard best at the carotid artery during exercise in healthy individuals can be used as a means for assessing post-concussion injury exertion tolerance. Typically there are no arterial sounds heard at the carotid artery in healthy individuals. Bruit, heard at rest, is an indicator of cardiovascular disease. Listening for a flow murmur or bruit-like sounds during exercise may indicate brain blood flow autoregulation and that this audible change in brain blood flow autoregulation could be used to assess exercise tolerance. We present very preliminary evidence supporting our hypothesis in that a transient exertion-related carotid (TERC) murmur is heard at a HR (HR) of approximately 150 beats per minute (bpm) in healthy individuals and 120bpm in concussion patients. Future prospective clinical studies to validate this hypothesis and these methods may aid clinicians who manage concussion patients by using this method to help guide exertion protocols.

In brief When an active patient sustains a hand or finger injury, a digital nerve block is often the appropriate anesthetic technique. A thorough knowledge of the area's anatomy, the materials needed, the proper technique, and the potential complications can help the primary care physician perform the procedure smoothly.
RESUMEN
In brief Two soccer goalies, a 20-year-old woman and a 28-year-old man, sustained head injuries as they fielded shots on goal. One was kicked, the other kneed by another player. The female goalie suffered a mild concussion. The male goalie lost consciousness and was transported to a hospital where he scored a 7 of 15 on the Glasgow Coma Scale. Three months after the injury, he still suffered from decreased concentration and hearing loss and had not returned to work.
