13 MINIMAL INVASIVE HIP SURGERY: FICTION OR REALITY?

The organism – reality or fiction?

Dark Energy : fiction or reality ?

Is Dark Energy justified as an alternative to the cosmological constant Λ in order to explain the acceleration of the cosmic expansion ? It turns out that a straightforward dimensional analysis of Einstein’s equation provides us with clear evidences that the geometrical nature of Λ is the only viable source to this phenomenon, in addition of the application of Ockham’s razor principle. This con...

Rossi’s reactors--reality or fiction?

A tabletop prototype of a new kind of nuclear reactor was demonstrated recently at the University of Bologna. This note addresses conceptual difficulties associated with the reported features of the device.

Molecular reduction: reality or fiction?

Neurophysiological research suggests our mental life is related to the cellular processes of particular nerves. In the spirit of Occam’s razor, some authors take these connections as reductions of psychological terms and kinds to molecularbiological mechanisms and patterns. Bickle’s ‘intervene cellularly/molecularly and track behaviourally’ reduction is one example of this. Here the mental is b...

Minimally invasive hip surgery.

Describe the most common techniques used for minimally invasive hip surgery. Certainly the most commonly described approaches in the literature are the posterior and direct anterior. The posterior approach is essentially the same as what surgeons have done traditionally but with a shorter incision and less dissection of the deep musculature. The 2-incision approach, which I prefer, has fallen o...
