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.

Radiosurgery is increasingly used to manage malignant melanoma brain metastases. We reviewed our series of patients who underwent radiosurgery for melanoma brain metastases to assess clinical outcomes and identify prognostic factors for survival and cerebral disease control. ⋯ Gamma knife radiosurgery for malignant melanoma brain metastases is safe and effective and provides a high rate of durable local control. Improved survival can be achieved in patients with single metastasis, controlled systemic disease, and a high Karnofsky performance score.

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.
