Ligaments

Question 1

TRANSVERSE LIGAMENT

Answer 1

• 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

Question 2

LIGAMENTUM TERES

Answer 2

• encapsulates FOVEOLAR ARTERY to protect as femur moves
• extends out from border of acetabulum
• intrinsic ligament

Question 3

ILIOFEMORAL LIGAMENT

Answer 3

• “Y” Ligament
• runs AIIS —> acetabular rim (intertrochanteric line)
• limits HYPEREXT & ADD
• anterior to AOR
• capsular ligament

Question 4

PUBOFEMORAL LIGAMENT

Answer 4

• runs SUP PUBIC RAMUS —> INF NECK
• limits HYPEREXT & ABD
• anterior to AOR
• capsular ligament

Question 5

ISCHIOFEMORAL LIGAMENT

Answer 5

• runs ISCHIAL ACETABULAR RIM —> Intertrochanteric line

- limits HYPEREXT & IR

Question 6

CORONARY LIGAMENT

Answer 6

• meniscal ligament
• “crown”
• bind convex (outer) surface of MENISCI to TIBIA

Question 7

TRANSVERSE LIGAMENT

Answer 7

• meniscal ligament

- MM anterior horn —> LM ant horn

Question 8

INTERCONDYLAR LIGAMENT

Answer 8

• meniscal ligament

- meniscal horns —> intercondylar eminence

Question 9

POSTERIOR MENISCOFEMORAL LIGAMENT

Answer 9

• meniscal ligament
• aka “ligament of Wrisberg”
• LM posterior horn —> Medial femoral condyle
• ONLY ONE TO ATTACH TO FEMUR

Question 10

MCL

Answer 10

• thickening of joint capsule
• capsular ligament
• med epicondyle femur —> medial proximal tibia
• resists VALGUS stress

Question 11

LCL

Answer 11

• extrinsic ligament
• lateral femoral condyle —> head of fibula (runs underneath biceps femoris attachment)
• resists VARUS stress
• 2˚ restraint (tibia ER & post tib displacement)

Question 12

IT Band

Answer 12

• 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

Question 13

OBLIQUE POPLITEAL LIGAMENT

Answer 13

• lat femoral condyle —> med tibial condyle
• reinforce posterior capsule
• limits HYPEREXTENSION

Question 14

ACL

Answer 14

• 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

Question 15

ARCUATE LIGAMENT

Answer 15

• lat condyles of femur & tibia —> head of fibula
• reinforce POST CAPSULE
• limits HYPEREXT
• 2˚ function: limits varus loading

Question 16

SPRING LIGAMENT

Answer 16

• PLANTAR CALCANEONAVICULAR LIGAMENT
• runs calcaneus —> navicular
• supports: talonavicular jt, longitudinal arch, transverse tarsal joint

Question 17

TALOCALCANEAN LIGAMENT

Answer 17

• runs SUP CALCANEUS —> INFERIOR TALUS
• in intertarsal canal
• intrinsic ligament
• restricts TRI-PLANAR movements

Question 18

SHORT PLANTAR LIGAMENT

Answer 18

• PLANTAR CALCANEOCUBOID LIGAMENT
• runs CALCANEUS —> PROXIMAL CUBOID
• just deep to long plantar ligament

Question 19

DEEP TRANSVERSE METATARSAL LIGAMENT

Answer 19

• runs medial 5th MTP —> lateral 1st MTP
• serves as attachment fo ADD HALLUCIS (transverse head)
• also attaches MTs together

Question 20

LONG PLANTAR LIGAMENT

Answer 20

• 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

Question 21

PLANTAR APONEUROSIS

Answer 21

• runs PROXIMAL CALCANEUS —> PROX PHALANGES

- supports longitudinal arch

Question 22

MEDIAL ANKLE LIGAMENTS

Answer 22

• “DELTOID LIGAMENT” - restricts EVERSION
  1. Anterior tibiotalar
  2. Tibionavicular
  3. Tibiocalcanean
  4. Posterior tibiotalar

Question 23

LATERAL ANKLE LIGAMENTS

Answer 23

• restrict INVERSION
  1. Anterior talofibular (ATFL)
  2. Calcaneofibular (CFL)
  3. Posterior talofibular (PTFL)

Question 24

PCL

Answer 24

• 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
