31
Where does the common fibular nerve bifurcate?
Small space through fibularis longus (near head and neck of fibula)
32
What muscles are found in the posterior compartment of the leg? 7

33
What nerve innervates the muscles found in the posterior compartment of the leg?
Tibial nerve
34
What actions do the muscles found in the posterior compartment of the leg do?
Plantarflexion | Eversion
35
What separates the superficial muscles in the posterior compartment to the deep muscles? Bonus points for number of muscles and names
Separated by a band of fasica 3 - Superficial Gastrocnemius Soleus Plantaris 4- Deep Popliteus (Tom dick and Harry) TP, FDL, FHL
36
What 2 ways (movement/force) can cause the ACL to tear?
Hyperextension of the knee joint, | Large force to the back of the knee with the joint partly flexed
37
What event can cause the PCL to tear?
Dashboard injury When the knee is flexed, and a large force is applied to the shins, pushing the tibia posteriorly e.g. hitting the dashboard in a car accident
38
What bursa becomes inflammed in Housemaids knee?
Suprapatella bursa
39
What bursa becomes inflammed in Clergyman's knee?
Infrapatella bursa
40
What bursa becomes inflammed in a Baker's cyst?
Its the synovial fluid from the joint that expands out into the popliteal fossa
41
What are the two functions of menisci?
To deepen the articular surface (increasing stability) | To act as shock absorbers.
42
Which of the menisci is larger/more C shaped?
Medial meniscus
43
What is the name of the gooses foot? | What side of the leg is it found?
``` Pes anserinus Medial side (goose, MEALdial side) ```
44
What muscles are involved in the gooses foot?
Pes anserinus aka the SGS (Special Goose Service) (anterior to posterior) Sartorius Gracilis Semitendinosus
45
What nerve is affected if you see a Trendelenburg sign/gait?
Superior gluteal nerve
46
What is a Trendelenburg test? | If there is a left positive what does it mean?
Get the patient to stand on each leg seperately. The hips should stay horizontally aligned. If there is a hip drop (e.g. on the left) then there is a problem with medius and minimis (on the right)
47
Borders of the popliteal fossa?
Superomedial border: Semimembranosus. Superolateral border: Biceps femoris. Inferomedial border: Medial head of the gastrocnemius. Inferolateral border: Lateral head of the gastrocnemius and plantaris

56
What is the saphenous nerve a branch of?
Femoral nerve
57
Lateral cutaneous nerve of the thigh innervate?
Skin on lateral thigh
58
Whats the floor of the femoral triangle?
IPA make you hit the floor Iliosoas Pectineus Adductor longus
59
Whats the roof of the femoral triangle?
Fascia lata
60
Borders of the femoral triangle?
Inguinal ligament Adductor longus Sartorius
61
Deep gluteal muscles have what action?
Lateral rotation
62
Patella fractures can be...?
Displaced or undisplaced
63
Which ankle ligaments are weaker?
Lateral (think what ankle sprain is easier) Anterior talofibular ligament is the lateral ligament most at risk of irreversible damage.
64
Name the bones in the transverse arch?
Cuboid and cuneiform bones
65
Whats a bunion?
Hallux Valgus medial deviation of the first metatarsal bone and lateral deviation of the hallux
66
In terms of gait - what is the difference between walking and running?
Walking has a phase where there is double support. Both legs touch the ground, whereas in running there is a phase where both legs are off the ground
67
