Ankle and foot mishaps Flashcards
1
Q
what does talor shift mean?
A
- ligament injury may cause shift in talus.
2
Q
how does treatment for ankle fractures vary on if it’s stable or unstable?
A
- stable fractures : weight bearing, need cast or boot for comfort and low rate of complications.
- unstable fractures require surgical stabilisation and high risk of complications in diabetes and poor blood supply.
3
Q
why is achiles tendon rupture so significnt?
A
- Achilles is the largest and most powerful tendon in the body.
- often at vascular watershed 6cm proximal to insertion of Achilles into calcaneal tuberosity which has decreased thickness so more susceptible for tear.
4
Q
what would the symptoms be is a ruptured Achilles tendon?
A
- sudden severe pain at back of ankle.
- palpable depression in tendon.
- inability to push off when walking.
5
Q
what investigations would be carried out at ruptured Achilles tendon? what would the treatment be?
A
- thompson’s test also called simmond’s test when calf squeezed no plantar flexion.
- MRI and USS to diagnose.
- treatment with air-cast boot holding foot in correct position or surgery if young.
6
Q
what is the halux valgus complication?
A
- Hallux (big toe) valgus (distal part deviated laterally).
- varus deviation of first metastarsal.
- valgus deviation or lateral rotation of hallux.
- prominence of first metatarsal head with or without callus.
- caused by genetics or shoe-wear.
7
Q
what is the treatment for hallux valgus?
A
- change shoes and attitudes.
- operation.
8
Q
what is hallux rigidus?
what would the treatment be?
A
- osteoarthritis of 1st metastarsophalengeal joint.
- Xray may show loss of joint space, extra bone structures, cysts.
- painkillers, steroids.
- surgery realign, remove extra bony structures, fuse, replace in arthroplasty.
- fusion or joint replacement where fracture created and stabilised and allowed normal fusion.
9
Q
how would you treat ankle arthritis?
A
- arthrodesis (fusion).
- arthroplasty (ankle replacement) .
10
Q
what is planovagus and how is it treated?
A
- change in shape due to tibialis posterior disfunction leading to pain behind medial malleolus.
- treatment include insoles for medial arch support, physiotherapy, reconstruction if flexible foot, arthrodesis if stiff foot.
11
Q
why is diabetes a risk factor for foot complications?
A
- because diabetes causes loss of protective sensation in foot so injuries may lead to severe infections as undetected.
- debridement required.
12
Q
what is charcot arthropathy?
A
- a complication of diabetes leading to massive deformity and bone loss, loss of soft bone due to inflammation and lack of pain.
- patients obese, immunocompromised with poor diabetic control to complicate matters.
- cast to protect foot.
