What nerve block is ideally given for a TSA?
interscalene nerve block
Skin incision for TSA extends distally from the posterior of the ______ to the anterior _______ area.
posterior of the AC joint to the anterior deltoid/pectoral area
______ fibers are split and reflected with temporary sutures to reveal the GHJ when performing a superior approach of a traditional TSA.
anterior deltoid
(true/false) The Long head of the biceps removed from the bicipital groove and dislocated posteriorly during a traditional TSA procedure
true
(minimal/maximal) resection of the humeral head is needed for a TSA.
minimal
What is the order of muscle closure when the TSA is complete?
- pectoral
- deltoid
- cutaneous tissue
What is different about a humeral hemiarthroplasty compared to a TSA?
Similar procedure but only the humeral head is replaced
What are the indications for a humeral hemiarthroplasty?
- avascular necrosis of HH
- OA/RA or degeneration of the glenoid
- 2+ proximal humeral fractures
What are the indications for a TSA?
- chronic pain relief
- improve function of the GHJ
- OA/RA
- proximal humeral fracture
- necrosis
What must a person have to get a TSA performed?
intact glenoid component and sufficient RTC muscles
What are contraindications of TSA?
- infection
- dysfunction/paralysis of RTC muscles
- septic arthritis of GHJ
- severe bone loss >40%
Neuropraxia of the ____ related to traction is a common nerve injury assoc. with shoulder arthroplasty
brachial plexus
What should a patient’s positioning be like when in early post-operative care?
HOB 30-60 degrees
towel/pillow under involved arm w/ relaxed shoulders
avoiding hunched position
A sling for post-operative care of TSA should prevent _____.
extension because it places stress on the subscapularis tendon
What devices decrease the likelihood of a deep vein thrombosis?
antiembolic devices
