When performing a Cranial Drawer Test on a canine patient to assess the integrity of the Cranial Cruciate Ligament (CCL), what is the correct hand placement and expected finding for a positive result?
-
A
One hand stabilizes the tibia while the other moves the femur cranially; excessive caudal movement of the femur indicates a rupture.
-
B
One hand stabilizes the femur by placing the thumb on the lateral fabella and the index finger on the patella, while the other hand moves the tibia cranially; excessive cranial tibial translation indicates a rupture.
-
C
Both hands are placed around the stifle to apply a rotational force; a palpable 'clunk' as the tibia subluxates indicates a rupture.
-
D
One hand flexes the hock while the other palpates the tibial tuberosity; cranial movement of the tuberosity during hock flexion indicates a rupture.
