Surgical Interventions and Postop Management Flashcards
4 types of TSA prosthetic desgins
- unconstrained
- semiconstrained
- reverse ball and socket
- constrained
Which TSA designs allows for the greatest freedom of motion?
unconstrained
Does the RC have to be intact for an unconstrained design?
yes it must be
Does the RC have to be intact for a semiconstrained design?
It may be mildly impaired prior to repair
Describe a reversed ball and socket
The glenoid is ball shaped and the humerus is the socket component
What is the purpose of a reverse TSA?
It provides stability for RC deficient shoulders that cannot be repaired
Describe the constrained TSA design
it provides the greatest amount of stability due to its fixed fulcrum ball and socket design
Which TSA design is rarely used and why?
constrained because of its high rate of loosening and failure of components
What is the major difference between a TSA and rTSA?
In a rTSA the deltoid becomes the primary mover of the GH joint because the RC is torn.
In a TSA, functioning RC muscles move the GH joint.
What are 3 physiological complications after TSA?
Pulmonary embolism
DVT
Infection
What are 4 anatomic complications after TSA?
- axillary or suprascapular nerve damage
- dislocation
- fracture
- re-tearing of the RC
How is the extremity positioned after a TSA?
Elbow flexed to 90
Shoulder flexed 10-20 with slight abduction and IR
What 7 things should you avoid after a TSA
- end-range stretching (especially to subscapularis)
- AROM in antigravity position
- dynamic shoulder exercises
- resistance exercises
- weight bearing on operative UE
- lifting
- reaching behind the back
If the rotator cuff was repaired during TSA, how long until AROM and light isometrics?
6 weeks
Which aspect of the capsule should you avoid stress to after a TSA?
anterior
Avoid hyperextension and abduction
Which 2 muscles should you concentrate on the most after TSA?
Serratus anterior and trapezius
What are the 4 criteria to advance to the moderate phase after a TSA?
- 90 degrees of passive elevation
- 45 degrees of ER
- 70 degrees of IR in the plane of the scapula with minimum pain; or full, PROM with little to no pain
- NO subscapularis tendon pain with resisted, isometric IR
What are the 5 criteria to advance to the minimum phase after a TSA?
- at least 130-140 degrees of PROM shoulder flexion
- at least 120 degrees of PROM abduction
- 60 degrees pain free PROM ER
- 70 degrees PROM IR
- Strength of rotator cuff and deltoid muscles 4/5
What is the keystone to the rehab process after a TSA?
POSTURAL CORRECTION
What motions should be avoided for 12 weeks following a rTSA?
shoulder extension past neutral and the combination of shoulder adduction and internal rotation
*This motion causes dislocation
Which RC muscle is the most commonly torn?
Supraspinatus
If a RC tear is greater than _ cm a surgical repair is pursued
