Canine Pelvic Limb Fibrous Structures Flashcards
Sarcotuberous Ligament
runs from transverse processes of last sacral and first caudal vertebrae to the lateral angle of the ischiatic tuberosity
- absent in the cat
Crural Extensor Retinaculum
- proximal to flexor surface of tarsus, on distal cranial tibia
- holds down tendons of long digital extensor and cranial tibial
Tarsal Extensor Retinaculum
- attaches to the calcaneus
- holds down tendon of long digital extensor
Flexor Retinaculum
binds tendon of lateral digital flexor in groove over the sustentaculum tali
Femoropatellar Ligaments
- medial and lateral ligaments
- thin fascial bands extending between the patella and gastrocnemial sesamoid bones
Lateral and Medial Menisci
- between femoral and tibial condyles
- semilunar in appearance
- secured by meniscotibial ligaments
- lateral meniscus attached to intercondylar fossa of femur via meniscofemoral ligament
Medial and Lateral Collateral Ligaments
medial: extends from medial epicondyle of femur to medial side of tibia
lateral: extends from lateral epicondyle of femur, over tendon of origin of popliteus, to head of fibula and lateral condyle of tibia
Cranial and Caudal Cruciate Ligaments
both attach within intercondylar fossa of femur
- Cranial: to caudomedial part of lateral condyle, and extends distocranially to cranial intercondylar area of tibia
- Caudal: to medial condyle, and extends to medial edge of popliteal notch of tibia
Tarsal Tunnel
- Dorsal: sustentaculum tali
- Lateral: calcanean tuber
- Plantar: flexor retinaculum
- contains tendon of lateral digital flexor
Plantar Annular Ligament
runs over the flexor manica on the distal end of the metatarsus
Proximal and Distal Digital Annular Ligaments
hold SDF and DDF in place at proximal and middle phalanges
Dorsal (Elastic) Ligament
attaches to inguinal crest of distal phalanx and base of middle phalanx
- allows cat to retract claws
Deep Inguinal Ring
borders
Cranial: caudal border of internal abdominal oblique
Medial: lateral border of rectus abdominis
Caudolateral: inguinal ligament
