Canine Flash Notes - Hip Dysplasia Flashcards
what is the signalment of dog usually affected by hip dysplasia?
juvenile dogs usually between 3-10 months old
what is the classic case presentation of a juvenile dog with hip dysplasia?
exercise intolerance, bunny hopping gait, positive ortolani sign, pelvic limb lameness, difficulty rising, & audible clicking when walking or rising
what is the classic case presentation of a mature dog with hip dysplasia?
weight-bearing lameness, pelvic musculature disuse atrophy, pain, & crepitus on hip manipulation
what are the radiographic methods of choice for diagnosing hip dysplasia?
pelvic rads
OFA - more subjective, must be atleast 2 years old
PennHIP protocol with the compression/distraction method - more objective, can be done as young as 16 weeks old, & the distraction index correlates highly with the likelihood of clinical disease
what is the surgical treatment of choice for a juvenile dog with hip dysplasia?
young, without degenerative joint disease - juvenile pubic symphosiodesis or triple pelvic osteotomy
what is the surgical treatment of choice for an adult dog with hip dysplasia?
with degenerative joint disease - total hip replacement or femoral head & neck ostectomy
what is the medical treatment of choice for hip dysplasia?
pain control - acutely with NSAIDS, chronic with tramadol, amantadine, & gabapentin
nutrition - prevent obesity, energy restricted diet, & high in omega-3 fatty acids
low impact exercise only
joint fluid modifiers
what is the prognosis of hip dysplasia?
fair to good - most will have improvement with medical & surgical intervention
how is hip dysplasia prevented?
breed animals based on OFA/PennHIP results
low impact exercise
avoid high-energy diets
what is responsible for early clinical signs associated with hip dysplasia?
joint laxity is responsible for early clinical signs & joint changes
what are the 2 radiographic protocols used for diagnosing hip dysplasia?
OFA & PennHIP
