Week 2 Masterclass Flashcards
What are the 3 joints of the midfoot
tibiofibular, talocrural, subtalar
What movements can the talocrural joint perform
DF and PF
What is the nerve supply for toe ext
Deep peroneal nerve
How much dorsiflexion ROM do you typically need to descend stairs?
20 degrees
How can muscle tightness or contractures be identified during an assessment of range of motion in the calf?
If gastroc is tight, the ankle ROM is limited with the knee extended.
If soleus is tight, ankle ROM is limited with knee flexed
What movement injures ATFL
flexed, inverted and adducted position
What movement injures deltoid ligament
flexed, everted and abducted
What bony landmark does the flexor hallicus run underneath
Sustentaculum Tali
Describe what happens to the talus during DF
Talus slides posteriorly on the tibia causing the anterior surface to become compressed
Describe what happens to the talus during PF
Talus glides anteriorly on the tibia, causing the anterior surface to become stretched
What movements make up pronation
Dorsiflexion, Eversion and abduction
What movements make up supination
Plantarflexion, Inversion and adduction
What are the joints of the foot
Subtalar (rearfoot)
Transverse Intertarsal (mid foot)
Tarsometatarsal
Metatarsophalangeal (MTP)
Interphalangeal
What are causes of pain in the achilles which is often missed
Achilles rupture
Referred pain from peripheral nerves or lumbar spine
Sever’s disease
Soondyloarthropathy
What is the Ottawa ankle rule
X-ray if:
There is pain/tenderness over malleoli 6cm proximally
There is pain/tenderness over navicular
Tenderness over base of 5th metatarsal
Inability to weightbear for at least 4 steps after the time of injury and at time of evaluation
How to rule out ligament rupture of the ankle
No haematoma
No pain on palpation
Negative anterior drawer test approximately 5 days after the trauma
What is the Ottawa ankle rule used for
To rule out fracture, subtler dislocation or lisfranic injury (high sensitivity. Rule out. SnOUT)
What is your diagnosis if the pt hears a popping sound in their ankle?
Does not mean fracture, acute ankle sprain is still a possibility
What movement would cause pain in a lateral ankle sprain
Supination
Special tests for ATFL
Anterior Draw Test
Special tests for Calcaneofibular ligament injury
Talar tilt test
When is pain most common in plantar fasciopathy pt
Start and end of day
Do heel spurs contribute to plantar fasciopathy
No. Heel spurs are normal
What can be observed in plantar fasciopathy pt
Flat feet or high arches. Overpronation during gait
