Osteoarthritis and Total Hip Arthroplasty Flashcards
give some examples of disease that result in an end point of secondary OA
DDH, SUFE, AVN, FAI, septic arthritis
describe what osteoarthritis(OA) is
degenerative disease of synovial joints that causes progressive loss of articular cartilage
what groups of people is OA usually seen in
females > males, older age, genetic element, pre-existing hip problem
what clinical features are seen in the presentation of hip OA
groin pain, worse on activity, pain at night, start up pain, stiff on testing ROM
what changes are seen on radiograph of OA
joint narrowing space, subchondral sclerosis, osteophytes, cyst formation
what can be used in the management of hip OA
analgesia, weight loss, walking aids, physio, steroid injections, total hip replacement(THR)
what is considered in the surgical planning of a total hip arthroplasty(THA)
offset, leg length discrepancy, canal width, centre of rotation(high or low)
what is the indication of a THA in hip OA
PAIN
what are the benefits of a THA in OA patients
pain relief and secondary improvement of function
what are some of the risks involved in THA
scarring, bleeding, neurovascular damage, fracture, clotting, infection, leg length discrepancy, ongoing symptoms
what are the different prosthesis choices in THA
cemented, uncemented, hybrid
what are the different bearing choices in THR surgery
metal-on-poly, ceramic-on-poly, ceramic-on-ceramic
in what patients would a hybrid or cemented THA be used
hybrid = younger patients cemented = older patients
