Arthrology (LE) Flashcards
Sacrotuberous (attachments)
from posterior iliac spine and lateral margin of the sacrum to the ichial tuberosity
Sacrospinous (attachments)
from the ischial spine to lateral margin of the sacrum to the ischial tuberosity
Fibrous Joint Capsule (attachments)
from margin of the acetabulum to the neck, intertrochanteric line and intertrochanteric crest of femur
Iliofemoral (attachments)
from anterior inferior iliac spine to the intertrochanteric line of the femur
Iliofemoral (function)
limits extension of the femur on the acetabulum, limits external rotation of the femur
Pubofemoral (attachments)
from the iliopubic eminence and superior pubic ramus to the fibrous capsule
Pubofemoral (function)
limits abduction of the femur
Ischiofemoral (attachments)
From the ischium posterior to the acetabulum to the greater trochanter and iliofemoral ligament
Ischiofemoral (function)
Assists the iliofemoral ligmament in limiting extension of the femur
Ligamentum of the Head of the Femur (ligamentum teres)
from the fovea of the femoral head to the acetabular notch
Transverse acetabular lig. (attachments)
interconnects the margins of the acetabular notch
Fibrous capsule of knee (attachments)
from the margins of the femoral condyles to margins of the tibial condyle
Tibial (Medial) Collateral (attachments)
from the medial epicondyle of the femur to the medial condyle & shaft of the tibia deep to the sartorius and deep to the pes anserinus
Tibial (Medial) Collateral (function)
Stabilizes the medial aspect of the joint - resists valgus force at the tibiofemoral joint
Fibular (lateral) Collateral (attachments)
From the lateral epicondyle of the femur to the head of the fibula
Fibular (lateral) Collateral (function)
Stabilizes the lateral aspect of the joint, resist varus force at the tibiofemoral
Anterior Cruciate (attachments)
from medial part of the anterior intercondylar area of the tibia to the posterior part of the medial surface of the lateral condyle of the femur
Anterior Cruciate (function)
prevents posterior displacement of the femur on the tibia/prevents anterior displacement of the tibia on the femur, prevents hyperextension of the knee and limits rotation of the tibia on the femur
Posterior Cruciate (attachments)
from the posterior intercondylar area of the tibia to the lateral surface of the medial condyle of the femur
Posterior Cruciate (function)
Prevents the anterior displacement of the femur on the tibia/prevents the posterior displacement of the tibia on the femur
Medial Meniscus (attachments)
anterior and posterior regions of the intercondylar area of the tibia and fibrous capsule at the tibial (medial) collateral ligament
Lateral Meniscus (attachments)
anterior and posterior regions of the intercondylar area of the tibia
Patellar ligament (attachments)
from the apex of the patella to the tibial tuberosity
Patellar ligament (function)
resists knee flexion, serves as component of extensor mechanism for quadriceps mm. to extend tibia on femur
Medial Patellofemoral lig. (attachments)
proximal 50% of medial patella to the medial epicondyle of the femur
Medial Patellofemoral lig. (function)
limits patellar lateral displacement
Crural interosseous membrane (attachments)
From interosseous border of the tibia to interosseous border of fibula
Talocrural fibrous capsule (attachments)
from the borders of the articular surface s of tibia and malleoli to the margins of the trochlear surface of the talus
Medial Collateral (Deltoid) - (attachments)
from the medial malleolus to the talus, navicular, and sustemtaculum tali of the calcaneus
Medial Collateral (Deltoid) - (function)
Stabilizes joint and resists force EVERSION
Posterior Talofibular (attachments)
malleolar fossa of the fibula to the lateral tubercle of the talus
Posterior Talofibular (function)
restrict talocrural inversion
Calcaneofibular (attachments)
from tip of the lateral malleolus to the lateral tubercle of the talus
Calcaneofibular (function)
Resists calcaneal/subtalar inversion
Anterior talofibular lig. (attachments)
from anterior lateral malleolus of the fibula to the neck of the talus
Anterior talofibular lig. (function)
resists talocrural inversion and resists anterior translation of the talus
Long Plantar (attachments)
from the plantar surface of the calcaneus and cuboid to the plantar surface of the bases of the metatarsals
Plantar Calcaneocuboid (aka short plantar) - (attachments)
from calcaneus to the plantar surface of the cuboid
Plantar Calcaneonavicular (aka Sping ligament) - Attachments
from the anterior margin of the sustentaculum tali to the plantar surface of the navicular
Plantar Calcaneonavicular (aka Spring ligament) - Function
supports the medial longitudinal arch of the foot
