Dislocations and Sprains

I got diagnosed with insomnia, i'm tired of it.

Dislocation and Sprains

A dislocation is an injury caused when the regular position of a joint or other part of the body is disturbed. A closed dislocation is when there is no external wound. This injury would be considered as an acute injury; it is instant. The signs are that visually you can see a deformed or out of place joint, an example, the shoulder. More signs would be the swelling and bruising of the disjointed area. The symptoms of the dislocation would be; intense pain and the inability of movement around the joint. A sporting example of this could be a rugby player being tackled as his arm's in a vulnerable position.


A muscle strain is damaged caused by overstretching of muscle tissue. This occurs frequently when movement such as sprinting, stretching and kicking are carried out in an uncoordinated manner. The pressure put on the muscle tissue means it becomes overloaded and reaches it's breaking point. At this breaking point is when the muscle will tear or partial tear. There are three degrees dependent upon the severity of the muscle strain. These are categorised as 1st, 2nd or 3rd degree. Grade 1 strain is when individual muscle fibres are damaged. This is considered a mild strain which then requires 2-3 weeks of rest. Only 5% fibres or less are damaged. A Grade 2 strain would lead to more extensive damage done to muscle fibres; however this is not a complete rupture of the muscle but would require 3-6 weeks of recovery. A grade 3 strain is a complete rupture of the muscle. Surgery tends to be required in order to repair the muscle. The rehabilitation it can take up to 3 month.


A muscle strain is predominantly an acute injury; the individual can feel something is wrong straight away. However if the injury isn't allowed to heal fully then it could become a chronic injury. If the individual ignores the injury then a grade 1 strain has the potential to become grade 2 or even rupture completely. Signs and symptoms can be diagnosed instantly if it classes as an acute injury. The signs of this would be, swelling bruising or redness. The symptoms would be soreness, sudden onset of pain and stiffness. A sporting example of this would be a footballer over extending to reach a ball and straining their hamstring in the process.
