ortho Flashcards
(29 cards)
OCD locations in the dog
caudomedial humeral head, medial aspect of the distal humeral condyle, lateral or medial femoral condyle, medial or lateral trochlear ridge of the talus
OCD presentation
young large breed dogs that are lame and have pain and joint effusion lesions are often bilateral
OCD dx
Rads, look for defect in the subchondral bone with flattening or concavity of normal bone contour, sclerotic bone margins
non surgical management of OCD
NSAIDS, exercise restriction, omega 3, weight control
surgical management of ocd
via arthrotomy or arthroscopy, flap excision and joint mouse retrieval
what are palliative surgical techniques for OCD
curettage, abrasion, forage microfracture (bring in blood from deeper bone)
OCD prognosis best to worst
shoulder, stifle/ medial humeral condyle, talus
what is avascular necrosis, tx?
noninflammatory aseptic necrosis of the femoral head and neck in small breed dogs. causes mild intermittent lameness. tx with FHNE, or total hip arthroplasty
what is slipped capital femoral epiphysis
common in cats (young male neutered overweight cats), and is a non traumatic. causes lameness and pain, often bilateral. FHNE, or total hip
what is hypertrophic osteodystrophy
common in young rapidly growing male large breed dogs, causes swelling of the metaphyses of the radius, ulna, tibia, with a fever, anorexia, pain and can’t walk, shows as a double physis line. have to wait it out
what is hypertrophic osteopathy
periosteal reaction of the distal limbs, associated with primary or metastatic neoplasia in the chest.
what is panosteitis
self limiting non inflammatory disease of bone marrow of long bones, shifting leg lameness, pain on palp, usually thoracic limbs. shows as a patchy opacity on rads. treat with rest and pain meds
a negative cranial drawer test with a positive tibial thrust suggests
partial CCL tear, with the medial bandage tore, and the lateral bandage intact
clinical signs of cranial cruciate disease
lameness, pain, effusion, medial buttress, crepitation, instability on CD and TT, meniscal click on flexion
compare clinical signs of a partial versus a complete CCLR
complete is worse WITH exercise, partial is worst rising from REST with NO LAMENESS DURING EXERCISE, partial tear may resolve with rest
medical management of CCLR
WEIGHT CONTROL, pain meds, exercise modification
surgical management of CCLR
extracapsular techniques- lateral fabellotibial suture, tightrope, orthostay, fibular head transposition- depend on periarticular fibrosis and not ideal for large dogs
osteotomies- TPLO, TTA, CCW, CBLO, best for large breed dogs (any size dog) eliminate shearing forces/thrust
a + cranial tibial drawer in flexion but not extension suggests
a partial tear with the medial bandage tore
signs to observe in patellar luxation patient
instability in both directions, crepitus, degree of tibial tuberosity rotation, limb angle, location of patella (alta or baja) inability to extend limb
surgical tx of patella luxation
soft tissue release- rarely done alone, groove reconstruction procedures (trochlear chondroplasty, wedge recession, block recession), limb alignment procedures
radiographic signs of dysplastic hips could be seen at
7 weeks
breeds that get HD? ones that do not?
any breed, but typically large brees like german shepard, rotti, golden, st bernard)
sight hounds do not get hip dysplasia
prophylactic surgical management for HD
skeletally IMMATURE dogs with NO OA. can do juvenile pubic symphysiodesis (12-16w) or pelvic oesteotomy (younger than 10mo)
salvage surgical procedures for HD
patients greater than 1 yr with OA, FHNE, total hip arthroplasty
