MOD 7: Lecture 2

Dislocations and Subluxations

What are 3 types of joint instabilities? occult, subluxation, and dislocation
In which type of joint instability, when stress is placed on a joint do the joint surfaces lose their normal relationship, but remain partially in contact? subluxation
In which type of joint instability do the jt surfaces completely lose contact c eachother when stress is placed on the joint? Dislocation
Why should you also look for soft tissue injuries and fractures when you suspect dislocation? because the force required for the dislocation was so strong, pt may also have soft tissue injuries or a fx
What 2 structures is a traumatic subluxation of the ankle joint associated with? fx of the medial malleous and the distal end of the fibula ??that doesnt make any sense
Provide an example of a congenital dislocation / subluxation. congenital hip dysplasia (DHD)
Provide an example of a traumatic dislocation / subluxation. sports injury or car accident
Provide an example of a pathological dislocation / subluxation conditions related to RA, stroke, paralysis
What are the symptoms of a dislocation / subluxation. pain, swelling, deformity, decr. or abnormal movement, local tenderness, decr. Function, temporary paralysis b/c nerve could be compressed
How come once you dislocate a joint, you are more likely to do it again? because you can't get the joint back to its previous strenth and the underlying instability never recovers
