THA -exam 2 Flashcards
THA incision is relative to _________
Greater Trochanter
THA anterolateral approach:
no trauma to anti-gravity mm. but smaller view
a mini smaller incision with the same components takes more MD skill
more prominent vascular structures
THA posterolateral approach:
larger view but trauma to anti-gravity mm.
more common
Pre-op PT: purposes
sessions?
cost?
–assistive devices
–planning for recovery i.e. initial HEP
–expectation management
1-2 sessions
Cost reduction vs. no pre-op PT
THA Sx considerations: (5)
–cut capusle/extra capulsular ligs
–forcep and cut adjacent structures
–dislocate and replace hip (new acetabulum and head)
–close the capsule
–full range under anesthesia
THA Prosthetics:
–the _________is ___________out and the head of the ______ is cut off
–prosthesis fixation -
acetabulum; rasped out ; femur
—metals, ceramics, plastics
cemented
THA has a high injury/fx risk? T or F
false; low risk
Complications of THA:
heterotopic ossifications (1-5%) (fried chicken)
–formation of bone in abnormal location due to disease and/or direct trauma
Complications of THA:
-the bone grows into mm is called is known as
-ROM?
myositis ossification
P!ful and abrupt end feel are contradicted
replacing the head w/o replacing the acetabulum is called:
typically for the ______ pt. with _______ disease
hemiarthroplasty
non-arthritic pts.; Legg-Calve-Perthes
PT Rx: THA
follow protocols
What is one purpose you will NOT focus on with the THA that you did with OA?
cartilage integrity (not there)
THA Precautions (traditional) :
avoid hip flexion past 90º
avoid hip adduction past neutral
avoid rotation
–IR (post glide) past neural w/postlateral incision
–ER(ant, glide) past neural w/.anterolateral incision
THA Precautions (recent research)
no precaution NO increased incidence of dislocations
Prognosis THA:
@6 to 8mths. postoperatively physical; functioning has generally recovered to about 80% of that of controls
