RESUMO
The role of arthroscopy in the management of ankle and hindfoot pathology management has increased greatly in recent years with the potential for lower complication rates, faster recovery, improved access, and improved outcomes when compared to open techniques. Procedural variations exist as techniques aim to optimize lesion access, decrease operative time, and improve patient safety. Our goal is to summarize the described approaches and patient positionings common in minimally invasive arthroscopic surgery for anterior, lateral, and posterior ankle pathologies. A survey of pathology organized by arthroscopic approach and a review of recent advances in concomitant lesion management may be useful when planning arthroscopic foot and ankle surgery. LEVEL OF EVIDENCE: Level V, expert opinion.
RESUMO
A fibre optic evanescent wave sensor is used for the rapid detection of thrombin. Coagulation of solution phase fluorescently labelled fibrinogen to unlabelled fibrinogen bound to the surface of the fibre optic is observed in real time by the evanescent wave sensor. Thrombin concentrations down to 0.01 NIHml(-1) are detectable within 5 min. The potential application of this technique for rapid amplified immunosensing is discussed.
