The Popliteal Fossa & Leg (AP) Flashcards
1
Q
Distal articulations of the leg
A
- Tibia + fibula with talus of ankle joint
- Talus with calcaneum at subtalar joint
2
Q
Compartments of the leg
A
- Anterior
- Lateral
- Posterior
3
Q
What are the broad actions of each compartment of the leg?
A
- A = dorsiflexion, toe extension
- L = foot eversion
- P = plantarflexion, toe flexion
4
Q
Nerves supplying each compartment of the leg
A
- A = deep fibular
- L = superficial fibular
- P = posterior tibial
5
Q
Main arteries of lower limb
A
- Common femoral
- Profunda femoris
- Superficial femoral
- Popliteal
- Tibio-peroneal trunk
- Posterior tibial artery
- Peroneal artery
- Anterior tibial artery
6
Q
Main veins of the lower limb
A
- Dorsal venous arch
- Anterior tibial
- Plantar
- Posterior tibial
- Posterior fibular
- Popliteal
- Femoral vein
- Deep vein of the thigh
- Great saphenous
- Small saphenous
7
Q
Boundaries of popliteal fossa
A
- Semimembranosus (superomedial)
- Biceps femoris (superolateral)
- Medial head of gastrocnemius (inferomedial)
- Lateral head of gastrocnemius + plantaris (inferolateral)
8
Q
Contents of popliteal fossa (medial to lateral)
A
- Popliteal artery
- Popliteal vein
- Tibial nerve
- Common fibular nerve
9
Q
Clinical relevance of popliteal fossa
A
- Measure popliteal pulse
- Can get aneurysm in the artery
10
Q
Why is the popliteal pulse used instead of the posterior tibial pulse by clinicians?
A
Patients with peripheral arterial disease or diabetes may have poor circulation and have trouble asserting a posterior tibial pulse
11
Q
What type of joint are the proximal and distal tibiofibular joints?
A
- P = plane type synovial
- D = fibrous (syndesmosis)
