Equine Forelimb - Applied Anatomy Flashcards
Where would we preform arthrocentesis in the equine cubital joint?
lateral aspect
cranially and caudally to the lateral collateral ligament
Where would we perform arthrocentisis in the equine scapulo-humeral joint?
between the cranial and caudal eminence of the greater tubercle of the humerus
Which joint of the distal forelimb in the horse is the most stressed/worked/damaged?
metacarpophalengeal joint (aka fetlock joint)
What is articular windgalls/windpuffs in horses?
fluid filled swelling around the fetlock joint, associated with the tendon sheath
What is the clinical sign observed when there is a lesion in a section of the interosseous muscle?
fetlock sinks
What is the clinical sign observed when there is a lesion in a section of the superficial digital flexor tendon?
fletlock sinks slightly
What is the clinical sign observed when there is a lesion in both the interosseous muscle and superficial digital flexor tendon?
complete grounding of the fetlock
Describe capped elbow in the horse
inflammation of an inconsistent subcutaneous bursa over the olecranon process
Describe the condition known as “Sweeney” that is seen in the horse
damage to the suprascapular nerve
rapid atrophy of the supraspinatus and infraspinatus muscles - producing a prominent scapular spine
unstable shoulder - slips laterally
How are nerve blocks of the forelimb used in equine medicine?
diagnostic aid used to localize areas of lameness
start ditsally, move up proximally
Where would we perform a palmar/plantar digital nerve block?
along the medial and lateral edges of the flexor tendon at the level of the pastern joint
What nerves are targeted with the distal plamar/plantar digital nerve block?
medial and lateral palmar/plantar digital nerve
Where would we perform a proximal plamar/plantar digital nerve block?
on the abaxial side, just below the proximal sesamoid bone
Proximal plamar/plantar digital nerve block aka
abaxial sesamoidean nerve block
Where would we perform a low palmar nerve block?
adjacent to the dorsal surface DDFT but distal to the communicating branch
at the level of the buttons
