Ligaments Flashcards
1
Q
TRANSVERSE LIGAMENT
A
- spans entire length of acetabular notch
- allows foveolar artery to pass underneath w/o getting pinched by head of femur
- extends out from borders of acetabulum
- intrinsic ligament
2
Q
LIGAMENTUM TERES
A
- encapsulates FOVEOLAR ARTERY to protect as femur moves
- extends out from border of acetabulum
- intrinsic ligament
3
Q
ILIOFEMORAL LIGAMENT
A
- “Y” Ligament
- runs AIIS —> acetabular rim (intertrochanteric line)
- limits HYPEREXT & ADD
- anterior to AOR
- capsular ligament
4
Q
PUBOFEMORAL LIGAMENT
A
- runs SUP PUBIC RAMUS —> INF NECK
- limits HYPEREXT & ABD
- anterior to AOR
- capsular ligament
5
Q
ISCHIOFEMORAL LIGAMENT
A
- runs ISCHIAL ACETABULAR RIM —> Intertrochanteric line
- limits HYPEREXT & IR
6
Q
CORONARY LIGAMENT
A
- meniscal ligament
- “crown”
- bind convex (outer) surface of MENISCI to TIBIA
7
Q
TRANSVERSE LIGAMENT
A
- meniscal ligament
- MM anterior horn —> LM ant horn
8
Q
INTERCONDYLAR LIGAMENT
A
- meniscal ligament
- meniscal horns —> intercondylar eminence
9
Q
POSTERIOR MENISCOFEMORAL LIGAMENT
A
- meniscal ligament
- aka “ligament of Wrisberg”
- LM posterior horn —> Medial femoral condyle
- ONLY ONE TO ATTACH TO FEMUR
10
Q
MCL
A
- thickening of joint capsule
- capsular ligament
- med epicondyle femur —> medial proximal tibia
- resists VALGUS stress
11
Q
LCL
A
- extrinsic ligament
- lateral femoral condyle —> head of fibula (runs underneath biceps femoris attachment)
- resists VARUS stress
- 2˚ restraint (tibia ER & post tib displacement)
12
Q
IT Band
A
- dynamic ligament
- fascia from glut max & TFL —> lateral tibial condyle (Gerdy’s tubercle)
- resists VARUS loading
- assists ACL in resisting tibia IR & post FEMUR displacement when tibia is fixed
13
Q
OBLIQUE POPLITEAL LIGAMENT
A
- lat femoral condyle —> med tibial condyle
- reinforce posterior capsule
- limits HYPEREXTENSION
14
Q
ACL
A
- med aspect of lateral femoral condyle —> ant intercondylar fossa
- resists anterior tibial translation and/or post femur translation
- 2˚ resists varus/valgus stresses & tibia IR
15
Q
ARCUATE LIGAMENT
A
- lat condyles of femur & tibia —> head of fibula
- reinforce POST CAPSULE
- limits HYPEREXT
- 2˚ function: limits varus loading
16
Q
SPRING LIGAMENT
A
- PLANTAR CALCANEONAVICULAR LIGAMENT
- runs calcaneus —> navicular
- supports: talonavicular jt, longitudinal arch, transverse tarsal joint
17
Q
TALOCALCANEAN LIGAMENT
A
- runs SUP CALCANEUS —> INFERIOR TALUS
- in intertarsal canal
- intrinsic ligament
- restricts TRI-PLANAR movements
18
Q
SHORT PLANTAR LIGAMENT
A
- PLANTAR CALCANEOCUBOID LIGAMENT
- runs CALCANEUS —> PROXIMAL CUBOID
- just deep to long plantar ligament
19
Q
DEEP TRANSVERSE METATARSAL LIGAMENT
A
- runs medial 5th MTP —> lateral 1st MTP
- serves as attachment fo ADD HALLUCIS (transverse head)
- also attaches MTs together
20
Q
LONG PLANTAR LIGAMENT
A
- runs INF CALCANEUS —> DISTAL CUBOID & BASE OF LAT MTs
- supports calcaneocuboid joint
- short plantar ligament runs just deep to it
- creates tunnel for PER. LONGUS TENDON to run underneath it
21
Q
PLANTAR APONEUROSIS
A
- runs PROXIMAL CALCANEUS —> PROX PHALANGES
- supports longitudinal arch
22
Q
MEDIAL ANKLE LIGAMENTS
A
- “DELTOID LIGAMENT” - restricts EVERSION
1. Anterior tibiotalar
2. Tibionavicular
3. Tibiocalcanean
4. Posterior tibiotalar
23
Q
LATERAL ANKLE LIGAMENTS
A
- restrict INVERSION
1. Anterior talofibular (ATFL)
2. Calcaneofibular (CFL)
3. Posterior talofibular (PTFL)
24
Q
PCL
A
- intercondylar surface of med. femoral condyle —>post intercondylar fossa
- resists post tibial translation and/or ant femur translation
- 2˚ resist VARUS/VALGUS stress & limits LM motion
