22
Q

what supplies the articular capsule and ligaments of knee joint?

A

genicular anastamosis

23
Q

superficial and deep popliteal lymph nodes

A
  • superficial: cutaneous fluid (small saphenous vein)
  • deep: leg and foot (popliteal vein)
  • *proximal drainage accompanies femoral v to deep inguinal nodes
24
Q

most common distal femoral fracture

A

metaphyseal fx (transverse fx across shaft)

25
transverse fx involving epiphyseal plate
physeal fractures (Salter-Harris classificaton)
26
Salter-Harris Classification
1. through growth plate 2. through growth plate and metaphysis 3. through growth plate and epiphysis 4. through all 5. crush injury
27
* enlargement of gastrocnemius-semimembranosus bursa * assoc w/ DJD or joint injury * complications: * enlargement \> similar to DVT * rupture \> thrombosis or muscle rupture
Popliteal/Baker's Cysts
28
* enlargement of artery due to weakening of arterial wall * most common *true* version of this diagnosis * symptoms due to: thromboembolism, mass effect, rupture * present w/: claudication or ischemic pain at rest, sens/motor, pain behind knee
peripheral aneurysm
29
* atherosclerosis leading to occlusion * lack of blood flow \> pain * present w/: claudication, ischemic pain at rest, diffuse pain, non-healing ulcer, gangrene
30
2 types of weighted MRI
* T1: longitudinal relaxation time - time to realign with MF (fluid = dark) * T2: transverse relaxation time - time to lose phase coherence (fluid = light)
31
2 types of transducers for US
* high-frequency: 7-15, superficial structures * low-frequency: 1-3.5, deep structures
32
tibial nerve and posterior tibial vessels are deep to what structure?
transverse crural intermuscular septum
33
fabella is typically on which head of the gastrocnemius?
lateral head (to provide leverage)
34
proprioceptive organ for foot position (high density of prioprioceptive receptor end organs)
plantaris m.
35
used in reconstructive surgery of hand tendons
plantaris tendon
36
largest deep posterior muscle
flexor hallucis longus m.
37
palpate the dorsalis pedis pulse
lateral to the EHL tendon (or medial to the EDL tendon)
38
deep fascia of the leg continuous with the fascia lata
crural fascia
39
ridge on the lateral surface of the calcaneus
fibular trochlea
40
functions of musces with "fibularis" in the name
* fibularis tertius: dorsiflexion and eversion * fibularis longus and brevis: plantarflexion and eversion
41
from where do the dorsalis pedis a. and deep fibular n. emerge?
emerge beneath the inferior border of the extensor retinaculum
42
proximal attachment of the plantar aponeurosis
medial tubercle of the calcaneus
43
calcar femorale
dense, vertically oriented bone in posteromedial aspect of proximal femur
44
Stinchfield test
supine and resist hip flex with straight leg at 45 deg (+) if pain test: intraarticular pathology (OA)
45
failure of superolateral portion of the patella to fuse
bipartite patella
46
Screw Home
* tibia externally rotates 5 degrees in last 15 degrees extension * cruciates tighten and decreasee quad work while standing * popliteus unlocks tibia via IR to initiate flexion
47
Thessaly test
stands on affected leg at 20 deg knee flexion the nrotates on leg (+) pain
48
