Lecture 19 the shank, test 3

Question 1

three medical concerns with the tibial tuberosity

Answer 1

osgood schlatters, avulsion fracture, chronic dislocation of (petellar lig)

Question 2

what kind of joing is the proximal tib-fib joit

Answer 2

synovial plane joint with some gliding movement

Question 3

what movement occurs at the tib fib joint with knee flexion

Answer 3

bicepc and lcl tendon are slack and fibular shifts forward, opposite in extension

Question 4

what tendon provides support to the proximal tib-fib joint

Answer 4

po;liteal muscle, tendon

also semimembranosus fascia

Question 5

what are the palpable borders of the tibia?

Answer 5

ant, medial, medial surface

Question 6

where is the nutrient foramen on the tibia?

Answer 6

posterior, inf to soleal line

Question 7

what is the articulation with the fibula on the tibia called, distally?

Answer 7

fibular notch

Question 8

which distal tib-fib lig is essential for weight bearing? where is it?

Answer 8

transverse tibio fibular ligament, (posterior

Question 9

What usually happens with pathology of the posterior tib fib lig, why?

Answer 9

very strong, get avulution of maleouls (trimallelar fracture)

Question 10

what nerve and artery run in the anterior compartment?

Answer 10

deep peroneal n, ant tibial aa

Question 11

what artery run in the lateral compartment

Answer 11

peroneal aa and nerve

Question 12

what nerve and a runs in the posterior compartment?

Answer 12

tibial n, posterior tibial a–

Question 13

what divides the deep and superficial muscles of the posterior compartment?

Answer 13

deep muscles do not attache to the achiles

Question 14

what muscles would be effected by anterior compartment syndrom?

Answer 14

ta, extensor hl, edl (ie dorsiflexion)= drop foot during swing

Question 15

what are the 5 p’s indicating fasciatiomy for anterior compartment syndrom?

Answer 15

pain, palor, pulselessness, parasthesia, paralysis

Question 16

two extensor retinaculums:

Answer 16

superior, and inferior y

Question 17

what is unique (clinically useful) about the innervation to ehl?

Answer 17

only anterior peroneal nerve that is “deep” branch of the peroneal nerve, “can you wiggle toes”

Question 18

what is unique about peroneus tertius?

Answer 18

unlike the other two peroneals, does dorsiflexion with edl

Question 19

as deep peroneal nerve continues to foot, where does it provide sensory innervation to?

Answer 19

between toes one and two

Question 20

does peroneous longus touch the calcaneous?

Answer 20

no, it lies on top of the tendon to peroneous brevis

Question 21

what prevents bowstringing of the peroneal tendons?

Answer 21

superior and inferor peroneal reticulm (has a common synovial sheath)

Question 22

what is the blood supply for the lateral compartment?

Answer 22

does not have a dedicated blood supply; prox= perforating branches form atnerior tibial, dist= perforating branches from fibualr

Question 23

which is the deepest of the “ near the knee” muscles?

Answer 23

popliteus

Question 24

what structure is bakers cyst assc with?

Answer 24

inflammation of smimembranous bursa (and meniscal tear)

Question 25

tarsal tunnel syndrome would cause what symptoms?

Answer 25

inner surface of foot, pain under metatarsals (post tibial artery and nerve)

Question 26

which is more superficial, FDL or FHL?

Answer 26

FDL

Question 27

on what bone is the groove for the FHL?

Answer 27

calcaneous

Question 28

where does the fibular artery terminate?

Answer 28

in a network at the calcaneous

Question 29

which bv does anterior posterior and lateral compartments?

Answer 29

fibular artery
