If you have one, seek immediate medical attention. <br /> <br /> == Causes ==<br /> Joint dislocations occur when a sudden, great force is applied to the joint, such as a hard fall during parachuting or heavy blow during a vehicular crash. <br /> <br /> &lt;youtube&gt;<br /> title=&#039;&#039;&#039;{{PAGENAME}}&#039;&#039;&#039; <br /> movie_url=http://www.youtube.com/v/1JKcTsxHlQM<br /> &amp;rel=1<br /> embed_source_url=http://www.youtube.com/v/1JKcTsxHlQM<br /> &amp;rel=1<br /> wrap = yes<br /> width=750<br /> height=600<br /> &lt;/youtube&gt;<br /> <br /> == Risk factors ==<br /> Some people with genetic predispositions such as Ehlers-Danlos Syndrome or hypermobility syndrome are at increased risk. <br /> Those in high risk sport or occupations are also at risk.<br /> <br /> == Common joint dislocations ==<br /> The highest incidence of dislocations occurs in the shoulder, elbow, knee, and finger joints. <br /> <br /> == Shoulder dislocation ==<br /> * The shoulder is the most mobile joint in the human body and is therefore also the joint most prone to instability. <br /> * Anterior dislocations are by far the most common, representing 95­98% of shoulder dislocations. <br /> * This injury occurs when the shoulder is forcefully abducted, ­extended and externally rotated. <br /> * When such an injury occurs the patient is usually in considerable distress and tends to hold the arm close to the body. <br /> * On physical examination one may note that the convex contour of the shoulder is lost. <br /> * Care must be taken to evaluate for injuries to adjacent neurovascular structures<br /> [[File:X-ray of ventral dislocation of the radial head with calcification of annular ligament.jpg|thumb|[[Projectional radiography|X-ray]] of ventral dislocation of the radial head. There is calcification of annular ligament, which can be seen as early as 2 weeks after injury.]]<br /> == Symptoms ==<br /> Symptoms depend on the joint involved and usually involve some or all of the following symptoms:<br /> * Severe pain<br /> * Joint instability<br /> * Deformity of the joint area<br /> * Reduced muscle strength<br /> * Bruising or redness of joint area<br /> * Difficulty moving joint<br /> * Stiffness<br /> <br /> == Treatment ==<br /> * Joint dislocation needs immediate medical attention as it is a medical emergency. <br /> * Treatment depends on which joint you dislocate and the severity of the injury. <br /> * It might include manipulations to reposition your bones, medicine, a splint or sling, and rehabilitation. <br /> * When properly repositioned, a joint will usually function and move normally again in a few weeks. <br /> <br /> == Prevention ==<br /> * Prevention is better than cure. Wearing protective gear, reducing the risk of injury, and other preventive measures are recommended. <br /> * Once you dislocate a shoulder or kneecap, you are more likely to dislocate it again. <br /> * Wearing protective gear during sports may help prevent dislocations.<br /> <br /> ==Gallery==<br /> &lt;gallery mode=&quot;packed&quot; heights=&quot;220&quot;&gt;<br /> File:Dislocated finger.jpg| Dislocation of the left index finger<br /> File:Pinkie.jpg|[[Radiograph]] of right fifth [[phalanx bone]] dislocation<br /> File:Dislocated finger x-ray.JPG|[[Radiograph]] of left index finger dislocation<br /> File:Reduce dislocated spine, c. 1300.jpg|Depiction of reduction of a dislocated spine, ca. 1300<br /> File:MCCdislocation.PNG|Dislocation of the carpo-metacarpal joint.<br /> File:Dislocated Finger XRay.png|Radiograph of right fifth phalanx dislocation resulting from bicycle accident<br /> File:Dislocated Finger.JPG|Right fifth phalanx dislocation resulting from bicycle accident<br /> File:Lightbulb sign - posterior shoulder dislocation - Roe vor und nach Reposition 001.jpg|Shoulder dislocation before (left) and after (right) being reduced<br /> &lt;/gallery&gt;<br /> <br /> ==See also==<br /> * [[Buddy wrapping]]<br /> * [[Major trauma]]<br /> * [[Physical therapy]]<br /> * [[Projectional radiography]]<br /> * [[Spondylolisthesis|Listhesis, olisthesis, or olisthy]]<br /> <br /> {{Dislocations, sprains and strains}}<br /> <br /> {{Trauma |state=autocollapse}} <br /> {{Authority control}}<br /> {{stub}}<br /> {{DEFAULTSORT:Joint Dislocation}}<br /> [[Category:Contortion]]<br /> [[Category:Joints]]<br /> [[Category:Dislocations, sprains and strains]]<br /> [[Category:Emergency medical procedures]]<br /> <br /> &lt;/translate&gt;</div>
