Tibiofemoral instability is a common complication after total knee arthroplasty (TKA), accounting for up to 22% of all revision procedures. Instability is the second most common cause of revision in the first 5 years after primary TKA. In this study, 13 knees with tibiofemoral instability after TKA were identified among 693 consecutive primary TKA procedures. Patient demographics, body mass ind...

introduction prediction of thunderstorm is one of the most difficult issues in weather forecasting. deep convective clouds develop at small spatial and temporal dimensions about 1-10 km and 1-12 h. various thermodynamic parameters have been discovered over the past 40 years, according to data obtained by radiosounds. the capability of these indices in forecasting instability varies over time an...

STUDY DESIGN Retrospective study. PURPOSE To propose a new radiographic index for occipito-cervical instability. OVERVIEW OF LITERATURE Symptomatic atlanto-occipital instability requires the fusion of the atlanto-occipital joint. However, measurements of occipito-cervical translation using the Wiesel-Rothman technique, Power's ratio, and basion-axial interval are unreliable because the radi...

In the aftermath of the global financial crisis (2007-2009), policymakers in the developing countries and emerging economies have generally relied on macroprudential policies to achieve financial stability. Since the banking systemchr('39')s vulnerability plays an essential role in financial instability, and the banking systemchr('39')s stability is exposed to vulnerability, we examine macropru...
