Case Reports
Common peroneal nerve palsy as a complication of anterior cervical operation: a case report.
Common peroneal nerve palsy is a well-recognized complication following orthopedic procedure in and around the knee region. In neurosurgical practice, however, this kind of injury with regard to the patients' position is seldom reported. ⋯ We propose that such palsy may result from immobilization in a certain position instead of direct compression or traction of the corresponding nerve, although this is not proven. In this report, we suggest the possible risk factors, preventive measures, therapeutic options, and relevant outcome of this unwanted result.

Multicenter Study Clinical Trial
Evaluation of the Miethke dual- switch valve in patients with normal pressure hydrocephalus.
Especially in patients with normal pressure hydrocephalus (NPH), conventional differential-pressure valves are known to create nonphysiological negative intraventricular pressure values (IVP) when the patient moves into the upright position, with the consequence of numerous, sometimes severe, complications. The recently presented gravitational devices promise improvement, primarily in respect to this disadvantage. ⋯ The clinical course of patients suffering from NPH is mainly influenced by the stage of the disease, the time of beginning of the therapy, and the gravitational function of the implanted device. Based on our clinical experiences with the Miethke dual-switch valve (MD-SV), we underscore the advantages of this valve for the treatment of hydrocephalus, especially for patients with NPH.
