Cavernous sinus hemangiomas (CSHs) are uncommon lesions and comprise fewer than 1% of all parasellar masses. Because of their location, propensity for profuse bleeding during surgery, and relationship to complex neurovascular structures, they are notoriously difficult to excise. ⋯ To our knowledge, we describe one of the largest series of pure extradural transcavernous approaches to CSHs. CSHs are uncommon but challenging cranial base lesions. The extradural transcavernous approach allows complete excision with minimal mortality or long-term morbidity.

Lumbar spinal stenosis and spondylosis are major causes of morbidity among the elderly. Surgical decompression is an effective treatment, but many elderly patients are not considered as candidates for surgery based on age or comorbidities. Minimally invasive surgical techniques have recently been developed and used successfully for the treatment of lumbar spinal disease. Our objective was to examine the safety and efficacy of minimally invasive lumbar spinal surgery for elderly patients. ⋯ Minimally invasive lumbar spine decompression is a safe and efficacious treatment for elderly patients with spinal stenosis and spondylosis. Elderly patients should be considered good candidates for lumbar surgical decompression using minimally invasive techniques.

Comparative Study
In vivo study of head impacts in football: a comparison of National Collegiate Athletic Association Division I versus high school impacts.
To compare the frequency and magnitude of head impacts between National Collegiate Athletic Association Division I and American high school football players. The long-term goal is to correlate impact forces with injury patterns, leading to improvements in protective headgear. ⋯ Differences in the frequency and magnitude of head acceleration after impact exist between a Division I college team and a high school team. Compared with linemen, skill position players typically sustain the highest-level impacts. Additional data collection and analysis are required to correlate concussion diagnosis with acceleration magnitude and impact location.
