Apart from this, comparing the results of Figure 7 and 8, addition of bolts can lead to reduction of loosening
in individual bolts of the fastening system.
Given these findings, it was interpreted as aseptic loosening
of the acetabular component and the patient was proposed for revision surgery.
Because repetitive loads, shock, and loosening
must be decisively handled for implant use, traditional fasteners susceptible to self-loosening
rotational movement, stripping, and shearing are not always appropriate.
Recent advances in the better understanding of how organisms behave and of microbiological techniques such as sonification of the biofilm around the implant and prolonged culture have produced numerous reports showing that in cases labelled aseptic loosening
, organisms of low virulence such as Propionibacterium acnes (a skin commensal) can be identified in up to 72% of cases.
2) Other complications involve screw loosening
, screw fractures, cement failure, etc.
To decrease power consumption and increase the productivity of the loosening
process at the closing stage of the first phase, an impulse of compressed air at high pressure is supposed to the destruction zone.
The -200 and -200T have exhibited the same tendency regarding the loosening
of the forward pivot casting attach hardware.
With this came a loosening
of the intellectual and experiential bonds of connection and the fragmentation of the world into isolated objects and lonely individuals, and the desensitisation that accepted the ravaging of the natural and manmade worlds.
The screw is provided with an anti-loosening
thread locking patch to reduce the chance of loosening
For example, in some instances loosening
a frozen metal part requires that the molecular bond of oxidation be broken at the first molecular level.
in San Rafael, CA, is described as the only active mechanical fastener locking system that stops joint failure and production downtime because it prevents thread loosening
In addition, there is no need to worry about screws loosening
and intermittent signals as a result of vibration or temperature changes.
