Pelvic Limb Disorders Flashcards
What are the defining features of iliopsoas strain?
Decreased flexibility of iliopsoas (hip extension with IR)
Pain with palpation
Usually has defined MOI
Common in sporting dogs
What are the common defining features of fibrotic myopathy?
- Usually gracilis and/or semiten
- GSD or Belgian Shepherds, ~ 5 years of age, Probably male
- Insidious onset
- Shortened stride; rapid IR of paw
How does the dog present if there is a partial Achilles rupture and SDF is intact?
Stifle extension, hock flexion, digits FLEXED
How does the dog present with a complete Achilles injury?
Hock will drop to the floor
What is the common presentation for gait changes with hip dysplasia?
Waddle
Bunny hopping
Possible U or B lameness
Circumduction
Stiff legs
What are the differences between the PennHIP and the OFA?
- PennHIP can be done at 16 weeks, and OFA 2 years
- PennHIP requires sedation
- PennHIP is quantitative and OFA is qualitative
Describe the grades of patellar luxation.
- Starts in the groove and stays in the groove
- Starts in the groove, but you can push it out. It will go back in.
- It is out. You can push it back in, but it wants to go out
- It is out and will not go back in at all.
What are the passive stabilizers of the stifle?
CCL, meniscus, collateral ligaments
What are the active stabilizers of the stifle?
Quads, Hams, Gastroc
Describe the direction of the Cranial Cruciate Ligament? What motion does it restrict?
Goes caudolateral to craniomedial
Limits tibial thrust, prevents hyperextension and excessive IR
Describe the direction of the Caudal Cruciate Ligament? What motion does it restrict?
Goes craniomedial to caudolateral
Why is the medial mensicus more likely to be injured?
The lateral mensicus has stability from the meniscofemoral ligament
If we have + drawer in extension, this means…
there is a complete tear since BOTH bands of CCL should be taut in extension
What are the two bands of the CCL and when are they under tension (stifle position)?
Craniomedial - taut in flexion and extension
Caudolateral - taut in extension only
What is a normal tibial plateau angle?
25 degrees; excessive is 35
