MOD 7: Lecture 2
Dislocations and Subluxations
| Question | Answer |
|---|---|
| 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 |
| How would you treat a dislocation? | reduction and immobilize for about 3 wks |
