Reverse Shoulder Replacement Flashcards
when is a RTSR used
RC is completely torn
severe arthritis
failed conventional TSR
what are switched in rTSR
glenoid and humeral head components
where is the “ball” attached
where the glenoid was
where is the glenoid attached
attached to the top of the humerus
how does the deltoid move
raises the arm overhead instead of the RC
what is there a higher risk of
dislocation
after rTSR than conventional TSR
what should we avoid
shoulder extension beyond neutral
combination of shoulder ADD and IR for 12 weeks post-op
how can the shoulder dislocation
with IR and ADD w/ extension
expectation
normal/full AROM of shoulder is not expected post rTSR
what should we expect after rTSR
105 active flexion
what is the stability and mobility of the shoulder dependent on
deltoid and peroscapula muscles
what is the main shoulder muscle for rTSA
deltoid
what does the prosthesis change
the center of rotation
by moving it medially and inferiorly
changing the center or rotation causes
increase deltoid moment arm
deltoid tension to give a better line of pull
what does the deltoid replace
RC
becomes the primary elevator of the shoulder
general guidelines of rTSR
AROM, AAROM to neck, forearm, wrist and hand
delto-pectoral approach
AROM can begin @ 6 weeks
isometrics to deltoid can begin at 4 weeks
isotonic deltoid at about 12 weeks
shoulder flexion to 105-120 in scapular plane as tolerated
delo-pectoral approach –> guidelines
defer AROM for 6 weeks to allow for adequate deltoid healing
isometrics to deltoid can begin at 4 weeks –> guidelines
beginning deltoid and periscapular isometrics will assist in restoring initial deltoud fxn
provide stability to the GH joint
phase 1
0-4 weeks
goal of phase 1
maintain the integrity of the replaced joint
while restoring passive ROM
when is the pt in ABD splint –> phase 1
all the time besides therapy, bathing, HEP
there is no –> phase 1 guidelines
shoulder AROM, AAROM or PROM into IR
no reaching behind back, esp into IR
lifting objects
supporting of BW w/ hands
what should we place under the elbow –> phase 1 guidelines
small pillow/towel
while laying on back to avoid shoulder hyperextension
interventions –> phase 1
swelling management
ROM/mobility
