See these things kill animals the things they do can end up make them not live and that’s a problem. Existing studies evaluate the impacts either of screw design or of insertion technique, or of type of anchorage system ( screws or hooks) on pedicle screw stability. It is important to study and take into account new parameters that could influence pedicle screw stability.
Although this information would clearly help determine the best options for implantation of pedicle screws. The objective of this study is to evaluate pedicle screw fixation and thereby identify the most relevant parameters to be optimized in future experimentation on this porcine model. They chose animal model the landrace pig, known to most closely approximate the size and shape of human vertebrae. They were not the actors of those previous studies not affecting their spines: 4 of 30kg ( approximate age 90 days) and 4 of 50kg (approximate age 140 days) at the Institut Claude Bourgelat in …show more content…
On the one hand it is considered morally wrong to use animals in this way solely for human benefit.
On the other hand, removing animals completely from the lab would impede our understanding of health and disease, and consequently affect the development of new and vital treatments. Although sometimes these studies do reduce the quality of life of these animals, thorough regulations are in place to ensure that they are carried out in a humane way. The UK has gone further than any other country to implement thorough ethical frameworks when it comes to animals in research. The Animals Act of 1986 ensures that any research using animals must be fully assessed in terms of any harm to the animals. This involves detailed examination of the procedures and the number and type of animals used.
The use of animals in research is never undertaken lightly. Researchers working with animals carry out their experiments with extreme care to eliminate or minimise suffering.
Whenever possible painkillers and anaesthetics are used to manage pain , in the same way it is when an animal visits a vet.Over 4 million animal procedures are currently carried out each year for UK biomedical
