| Is hip dysplasia the same thing as hip arthritis? DJD? |
|
Definition
| No, dysplasia just means looseness. Arthritis and DJD involve osteophyte formation, thickening of the femoral neck, etc |
|
|
Term
| Are dogs with hip dysplasia born that way? |
|
Definition
| No, born with solid hips, but joint loosens over time |

|
Definition
-rear leg limping or short strides
-slow to get rear-end off floor and lie down
-lameness worse after getting up, then animal "warms" out of it
-difficulty climbing stairs or jumping
-day after exercise = bad
-cold damp days worst
-hocks knock together, may touch hocks to ground
-rear legs tucked under center of body, not wide stance
-(rear) may walk one foot in front of the other (tightrope-style)
-most pain when rear leg extended and abducted
-crepitation when DJD/arthritis set in
-subluxation on palpation, Ortolani's sign |
|

Term

Definition
-thumb on greater trochanter of femur
-extend and abduct leg
-healthy hip: trochanter pushes thumb out

Definition
grating/crackling/popping feeling felt while palpating and moving a joint; signifies inflammation
-may feel like shammy over a Brillo pad |
|
|
Term
| Before extending and abducting the rear legs to check for CHD, what should you do? Where should your hand be when you do the rear legs? |
|
Definition
-manipulate front legs first, to gauge animal's reaction
-then place hand over hip to feel for crepitation |
|
|
Term
| Describe a normal coxofemoral joint, an early CHD joint, and an older CHD/arthritis joint: |
|
Definition
-Normal: more than 50% femoral head in acetabulum
-Young CHD: less than 50% femoral head in acetabulum
-Old CHD/arthritis: less than 50%, osteophyte formation, thickened femoral neck, misshapen femoral head, uneven gap between head and acetabulum, etc |
|
|
Term
| Anatomical changes of CHD seen on rad: |
|
Definition
-acetabulum shallower ( < 50% femoral head in socket)
-flatter femoral head
-osteophytes on femur and acetabulum
-thicker femoral neck
-boxy femoral head |

Definition
-femoral head ostectomy
-"salvage procedure" = can be done at any age, typically when other conservation mngmt options have failed
-head of femur removed
-eliminates bone-on-bone pain
-can recover and walk near normal even when overweight |
|
|
Term
|
Definition
-total hip replacement
-artificial prosthetic implanted to replace socket and/or ball
-most expensive
-most like what humans get
-patients must meet certain criteria: not overweight, no cancer, no other illness, no neurologic problem |
