Canine Sacro-Pelvic Pathology Flashcards
Degenerative Myelopathy
progressive
no cure
onset between 8-14 yeras
large breed dogs - but have seen in small breeds - most likely german sheperds
NOT painful - there can be other diseases that are the cause of pain
clinical signs degenerative myelopathy
progressive ataxia
weakness
incontinence - fecal, urninary
leads to paraplegia
Causes of degenerative myelopathy
demyelination
axonal loss
genetic component
Diagnosis degnerative myelopathy
diagnosis of exclusion - MRI and myelogram
muscle testing
genetic testing - SOD1, univeristy of missouri
Degenerative myelopathy looks like
IVDD
Tumors
Cysts
LS disease
degenerateive myelopathy MRI to rule out
multiple other causes
Treatment of degenerative myelopathy
no proven treatments - antioxidant support and nutritional support
nursing care - keep them moving (underwater treadmills), disease progresses they weaken with exercise
Chiropractic care for degenerative myelopathy
careful - loss of muscle tone leads to increase in ROM of the joints
frequent care - weekly in advanced disease - early disease every 2-4 weeks
the only thing that I have found to help these patients (even better than acupuncture)
even needed after paraplegia due to increased work of the front end and weight balance
Lumbosacral disease/stenosis (cauda equina syndrome)
high motion joint
lumbosacral disease/stenosis (cauda equina syndrome) signalment
males more than females
large breed dogs more than small breeds
6-7 years onset - usually chronic use injury - degenerative process
overweight increases morbidity
L5 stenosis clinical signs
painful
trouble defacating
trouble posturing to defecate
incontinence
hind end weakness - MR for spinal cord compression - VLL to ligamentous change
L5 stenosis causes
chronic Hansen’s type II degenerative intervertebral disc disease of the L7-S1 intervertebral disc
hypertrophy and ventral folding of the interarcuate ligament
osteoarthritis and subsequent joint capsule proliferation of the articular facets of L7-S1 articulation
subluxation of the sacrum in relation to the L7 vertebra
L5 stenosis diagnosis
physical exam - rectal palpation
radiographs
myelogram
MRI
L5 stenosis treatment
pain management
weight management
stool softeners
L5 stenosis surgery
decompression
stabilization
