Remote cerebellar haemorrhage (RCH) is a well-described complication of supratentorial surgical procedures with an incidence ranging between 0.2 and 4.9 %, but is a rare complication of spinal surgery. We report a case of RCH in a 65-year-old woman who showed sudden mental deterioration 48 h after lumbar spinal surgery, which was complicated by incidental(More)
Microneedles, 0.2 mm o.d., were connected to a microsyringe and mounted on a micromanipulator. Under microscopic control, 0.01 ml of a 25% solution of FITC-labeled dextran-40 or dextran-150 were injected into the subepidermis at the big toe near the nailfold or in the medial ankle region. Fluorescence intravital microscopy revealed a network of lymphatic(More)
White atrophy (atrophie blanche) in the medial ankle region due to chronic venous insufficiency (stasis syndrome) was studied in 12 patients by fluorescence video microscopy [1,8]. After intravenous bolus injection of 1 ml of 20% Na-fluorescein the dynamic phenomena of transcapillary and interstitial diffusion of the dye were analyzed by a videodensitometer(More)
The Swiss Federal Office of Public Health demanded a nationwide HTA registry for lumbar total disc arthroplasty (TDA), to decide about its reimbursement. The goal of the SWISS spine registry is to generate evidence about the safety and efficiency of lumbar TDA. Two hundred forty-eight cases treated between 3-2005 and 6-2006, who were eligible for the 5-year(More)
The Swiss Federal Office of Public Health demanded a nationwide HTA-registry for cervical total disc arthroplasty (TDA), to decide about its reimbursement. The goal of the SWISSspine registry is to generate evidence about the safety and efficiency of cervical TDA. Three hundred thirty-two cases treated between 3.2005 and 6.2006 who were eligible for 5 years(More)
The objective of this study was to correlate various radiological parameters with clinical outcome in patients who had undergone lumbar total disc replacement (TDR). Lumbar TDR is one possible treatment option in patients with low back pain (LBP), offering an alternative to lumbar fusion. Favourable clinical outcome hinges on a number of radiological(More)
Small calvarial defects may be recontoured by Gore-Tex membranes or by micro burr hole covering plates in combination with bone dust. In extended defects the best primary and secondary results are obtained with splitted calvarium grafts due to their stabilizing and esthetic features. Micromeshes prevent contour disturbances in the contact zone of the(More)
