As previous studies have shown surgery frequently correlates with an increase in complications without improvement in outcome [19], the role of surgery should be limited to the rare patient with overt
mechanical instability.
Complications of prevertebral space infections include spinal cord compression and
mechanical instability of the spine.
The explanation is straightforward: The reason Threadripper has four dies under the hood with only two in use is because leaving them off would create
mechanical instability when the heatsink is mounted.
However the osseointegration which is defined as structural and functional bonding between living bone and the surface of implants is still not sufficient to which may ultimately lead to
mechanical instability and implant failure osseointegration.
Athletes with a complete rupture of the lateral ankle ligaments implying severe
mechanical instability on ultrasound examination were also excluded from this study.
In addition, mud weight (MW)/equivalent circulation density (ECD), mud cake (mud filtrate), hole inclination and direction, and drilling/tripping practice are considered the main parameters that affect wellbore
mechanical instability [9, 10].
The physician must always rule out pain caused by ongoing
mechanical instability (bony, ligamentous or both).
Our observations are supported by an animal study which also stated poor osseointegration when using magnesium-based screws resulting in
mechanical instability [15].
The compound exhibits poor bonding to dentin,
mechanical instability and continued resorption after placement.
In the fracture in most .of thermoplastic polymer materials, voids are formed by slipping between molecular chains comprising the oriented fibril formed by the plastic deformation, and the fracture occurs because the extension of voids satisfies the conditions of
mechanical instability. The conditions for this
mechanical instability depend on the strength to break the fibril and the intensity of the elastic strain energy that is the potential energy accumulated in the structure until the fibril is broken.
