Injections 1 Flashcards
What is Fenestration mean
multiple needle passes are placed under direct US guidance
What is a tenotomy mean
removal of calcium deposits
What is US-guided lavage and aspiration or barbotage?
calcific tendinosis with 1 to 2 needles placed under direct us guidance into the calcific deposit f/u by lavage
What is tendon scraping
needle or blade positioned outside the tendon adjacent and superficial to the paratenon for chronic tendinpathy
Why is image guidance needed
These 5 areas are a good response to insurance companies
What is the definition of in-plane and what is the goal for looking at the needle
goal is to see the entire full length reflection of the needle
image of maintaining proper in-plane orientation
needle best seen when more perpendicular to sound beam
In-plane approach with deeper targets
stay .5 inch offset from probe
Are probe covers required for US-guided injection?
No but they help
Contraindications to guided injections
Known allergy to the inectate
What are some relative contraindications
Coagulopathy or anticoagulant Hdmatoma formation
Contraindications and skin discoloration and cortisone
cortisone flare and treated with cold packs discoloration can be permanent but not harmful
Out of plane approach is best done with what kind of targets
Best done with shallow targets
