Equine PL Ligaments, Bursas, Etc. Flashcards
What is the malleolar bone?
The lateral malleolus in the ox; it is a completely separate bone
What is the fibularis (peroneus) tertius?
A connective tissue cord that is located deep to the long digital extensor m. and is firmly attached to the cranial tibial m. in the horse; it bifurcates at the hock into lateral and dorsal tendons; originates from the extensor fossa of the femur along with the long digital extensor m.
What is the cunean tendon?
The medial tendon of the cranial tibial m.; susceptible to irritation with subsequent inflammation due to bone spavin
What is the parapatellar fibrocartilage?
Medial fibrocartilage extension from the patella that curves over the proximal aspect of the trochlear tubercle (expanded proximal end of the medial trochlear ridge) when the patella is on the resting surface
What structures form the loop around the trochlear tubercle of the medial ridge of the trochlea of the femur?
The patella, parapatellar fibrocartilage, medial patellar ligament, and the intermediate patellar ligament
What are the femoropatellar ligaments?
Medial and lateral fascial bands that connect the patella to the caudal aspect of the femoral condyles
What is the medial patellar ligament?
Extends from the parapatellar fibrocartilage to the tibial tuberosity; this ligament is implicated in the “stifled” horse and is often cut in treatment of this condition
What is the intermediate patellar ligament?
Attaches the patella to the tibial tuberosity
What is the lateral patellar ligament?
Attaches the lateral aspect of the patella to the tibial tuberosity
What is the long plantar ligament?
Follows the plantar aspect of the calcaneus, passes over the 4th tarsal bone, and then continues distally onto the proximal part of the metatarsus; largely covered by the tendon of the SDF; commonly strained about the middle of its length –> curb
What is the proximal extensor retinaculum?
Binds tendons of the long digital extensor, fibularis tertius, and cranial tibial in place on the cranial and distal aspect of the crus
What is the middle extensor retinaculum?
Binds tendons of the long and lateral digital extensors, fibularis tertius, and cranial tibial in place on the dorsal aspect of the tarsus
What is the distal extensor retinaculum?
Binds tendons of the long and lateral digital extensors in place on the dorsal aspect of the proximal metatarsus
What is the plantar annular ligament?
Binds the tendons of the SDF and DDF in place on the plantar aspect of the fetlock
What is the proximal digital annular ligament?
A butterfly-shaped retaining fascial band that holds down the SDF and DDF tendons
