8b. MSK HAL - Worksheet Flashcards
what 3 bones make up the knee joint
femur
tibia
patella
what bone in the knee joint region is located in the region but is not contributing to the knee joint
fibula
what lines the surface of the bony condyles of knee
hyaline cartilage
how do you know if the knee is lat or medial side
fibula presence = lateral
what is special about the suprapatellar bursa
continuous with the knee joint cavity
all others are separate
what is contained within the joint capsule but which is not in the joint space itself
fat pad - infrapatellar
in what conditions can you expect to see an enlarged bursa of the knee
bursitis
intracapsular #
ruptured tendon
the quadriceps tendon and patella ligament insert where
tibial tuberosity
what are the 2 fibrocartilaginous discs that deepen the articular surface of the tibial condyles
menisci
in cross section what shape does the menisci have in the knee
wedge shaped
how can you tell the medial from lateral menisci
medial is more of a lunate C shape
lateral is ring shape
which menisci is more mobile and why
Lateral is more mobile as the attachments are closer together so more of a pivot point
how do the menisci appear in images
dark
where is the anterior cruciate ligament attached
attaches anteriorly on tibia and posterior of femur
where is the posterior cruciate ligament attached
attaches posteriorly on tibia and anteriorly of femur
what is the path of the anterior cruciate ligament
flows laterally to inside of lateral femoral condyles
what is the path of the posterior cruciate ligament
flows medially to inside of medial femoral condyles
where does the lateral collateral ligament attach
head of fibula
aside from bone what does the medial collateral ligament attach to
medial meniscus
which 3 bones make up the ankle joint
tibia, fibula and (trochlea of) talus
what are 5 bony landmarks of medial foot
big toe/MT1 tibia - medial malleolus head of talus sustentaculum tali of calcaneus navicular
what are 2 bony landmarks of lateral foot
fibula - lateral malleolus
cuboid
is the fibular relatively more ant or post at the ankle joint
posterior
what is the sinus tarsi and where is it located
in the subtalar joint between the talus and calcaneus
osseous tunnel
what 3 tendons pass behind the medial malleolus
tibialis posterior
Flexor digitorum longus
flexor hallicus longus
what 2 tendons pass behind the lateral malleolus
peroneal/fibularis longus and brevis
what other structure pass behind the medial malleolus into the tarsal tunnel along with tendons
posterior tibial artery and vein and tibial nerve
the tarsal tunnel is on the med/lat aspect
medial aspect
where does the calcaneal/achilles tendon insert
calcaneal tuberosity
what lies deep to the achilles tendon
kaegers fat pad
what are 4 ligaments of the ankle that is of interest
tibiocalcaneal
posterior talofibular
fibulocalcaneal
anterior tibiotalar
the shoulder joint is made primarily of the union of the humerus and scapula what other bone is involved in the shoulder complex
clavicle
what part of the scapula does the clavicle articulate with
acromion process
in what plane would you expect to pass through the scapula the quickest
coronal
approaching from posterior in the coronal plane what part of the scapula do you expect to encounter first
scapular spine
approaching from posterior in the coronal plane what part of the scapula do you expect to encounter last
coracoid process
approaching from lateral in the sagittal plane what part of the scapula do you expect to encounter first
acromion
what 2 muscles sit either side of the scapular spine on the posterior aspect of the scapula
supraspinatus
infraspinatus
the humerus head is larger/smaller than the glenoid fossa and what does this allow - what is a con of this
larger
allows greater range of motion but decreases stability
what group of muscles insert on the tubercles of the humerus
rotator cuff
which rotator cuff muscle passes inferior to the acromion before inserting on the humeral head
supraspinatus
what tendon runs between the 2 humeral tubercles
long head of biceps
what is special about the tendon of the long head of biceps compared to other muscles at the shoulder joint
it is intracapsular but extraarticular - ie it runs within the joint capsule
