TightRope fixation of complex acromioclavicular separation: A high-wire act
Numerous techniques have evolved for acromioclavicular joint fixation over the past decade to help decrease the risk of hardware complications and improve patient satisfaction. One of these techniques involves the TightRope system, which employs two titanium endobuttons to help reduce and secure the coracoclavicular joint. Clinical outcomes have been favorable, as orthopedic surgeons have gaine...
متن کاملLecture 8: Edge Tracking – Walking the Tightrope
In the subcritical transition scenario, there is typically a regime where the linearly stable basic state coexists with the turbulent state. The simplest model of this is a 1D system ẏ = y(12 − y)(y − 1) where the basic state is y = 0, the ‘turbulent’ state is y = 1 and there is an intermediate state y = 12 which separates initial conditions which become turbulent (if y(0) > 12 then y(t) → 1 as...
متن کاملWalking the Information Overload Tightrope
This chapter asks: What is information overload? At what levels of existence does it occur? Are there any features common to information overload at all these levels? What are information overload’s types? What are information overload’s current and future trends? What problems do they pose? How can they be addressed in both effective and morally justified ways?

متن کاملA legal and ethical tightrope
Among the many research fields that have found their way into the focus of public interest, seldom has one become such a hotly debated topic as research on embryonic stem cells. It has set churches and abortion opponents against scientists and patient advocates. Walking a tightrope, Western governments find it hard to draft regulations for this research field that address the concerns of both s...
متن کاملBalancing Selection: Walking a Tightrope
Combining modern transgenic techniques with fitness measurements and enzyme activity assays, a new study demonstrates a habitat-dependent tradeoff between two alleles of a key detoxification enzyme in fruit flies. The elegant findings provide concrete, elusive evidence supporting a foundational and controversial theory about the maintenance of genetic variation.
