Background: Surgical correction of adult degenerative scoliosis is a technically demanding procedure with a considerable complication rate. Extensive blood loss has been identified as a significant factor linked to unfavorable outcome.
Objective: To report on the complication profile and clinical outcomes obtained with less invasive image-guided surgical correction of degenerative (de novo) scoliosis in a high-risk population.
At present, subthalamic nucleus (STN) stimulation is the preferred procedure for the amelioration of motor symptoms in medication refractory Parkinson's disease. Results are however impaired by negative impacts on mood, cognition, incentive, and social judgment. Alternative targets are therefore explored.

Objective: To assess technical feasibility and radiographic results of image-guided less invasive correction of adult degenerative scoliosis.
Objective: To analyze the role of radiosurgery alone in patients with brain metastases. There were three specific study goals: 1) to determine whether survival of patients selected for this treatment approach can be predicted successfully by use of the recursive partitioning analysis classification defined by the Radiation Therapy Oncology Group; 2) to evaluate local control; and 3) to identify risk factors of cerebral failure.
Methods: A total of 101 patients with Karnofsky Performance Scale scores of at least 50 and up to three brain metastases, each 3 cm or less in maximum diameter, were treated with radiosurgery alone.
