Q

what does the anterior drawer test for the ankle involve?

A

Q

what effect do NSAID’s have on ankle sprains?

A
  • short term reduction in pain
  • longer use may delay natural healing as inflammation is a necessary component of healing

Q

what is the differnece between mechanical and functional instability?

Study These Flashcards
A
  • mechanical - joint motion** beyond the physiological limits** ie ligament laxity
  • functional - joint motion beyond voluntary contorl but within normal physiological limits
21
Q

what us chronic ankle instability - CAI?

Study These Flashcards
A
  • condition characterised by a recurring giving way of the lateral side of the ankle
22
Q

what are the key muscle groups for strengthening after the ankle injury?

Study These Flashcards
A
  • plantar flexors
  • dorsiflexors
  • inverters and evertors
23
Q

why us proprioception training so important for ankle sprains?

Study These Flashcards
A
  • it can improve how quickly the foot and ankle can respond to unsteadiness
  • balance training also heightens muscle strength, coordination and joint motion
24
Q

by what mechanism do medial ankle ligament injuries happen?

Study These Flashcards
A

eversion injury

25
why are medial ankle ligament injuries less common than the lateral ligament injuries?
* as the medial ligament is much stronger
26
what can a medial ankle ligament injury occur in association with?
* may occur with lateral ligament sprain (if the force is extrememely strong and goes from lateral to medial side ) * fracture of the medial ankle
27
what is tarsal tunnel syndrome?
entrapment of the posterior tibial nerve as it passes behind the medial malleolus
28
what are examples of causes of tarsal tunnel syndrome?
* tenosynovitis of the tib posterior tendon * excessive pronation (toes outwards) * overuse with excessive ankle movement * overly tight shoes or laces * RA
29
what are examples of clinical features of tarsal tunnel syndrome?
* severe sharp pain into the sole of the foot * aggravated by WB - walking, running and standing * can be worse in bed at night due to venous stasis * may have pins and needles - due to nerve compression * may have weakness of toe flexors
30
what does the conservative management of tarsak tunnel syndrome involve?
* pain reflief meds * local corticosteroid injetion * correct foot deformity - eg with orthotics * restore strength if possible * neural mobilisation
31
what does the **surgical management** of tarsal tunnel syndrome involve?
surgical decompression of nerve
32
what is mortons neuroma?
* benign (non cancerous) tumour of a nerve - the bifurication of the common plantar figital nerve
33
how can morton's neuroma occur?
* not clearly established * chronic trauma theory * entrapment theory * ischaemic theory
34
what are the signs and symptoms of morton's neuroma?
*** shooting, stabbing or burning **pain * worse with **WB** * feeling like a pebble or lump is stuck under foot * **pins and needles **and **numbness** * made **worse by tight shoes**, high heels etc * common at 3rd and 4th metatarsals
35
what kind of treatment can be very effective for morton's neuroma?
* corticosteroid injection
36
what is metatarsalgia?
* plantar pain in metatarsal region
37
what are examples of **causes** of metatarsalgia?
* hallux valgus (bunion @ big toe) * morton's neuroma * stress fracture * arthritis
38
what are the** signs and symptoms **of metatarsalgia?
* sharp aching or burning pain in the ball of the foot * worse with WB * may or may not have tingling or numbness
39
describe the epidemiology of an achilles tear
* more common in males * age 25-40 (high energy) and also 60+ (low energy) - more associated with a degenerate process * may be missed in 25% of patients * often dont have pain prior to rupture
40
what are key findings in the subjective exam of an achilles tear?
* acute injury * sudden onset - with sharp pain * audible snap or tear * may report swelling or brusing
41
what does the physical exam for an achilles tear involve?
* positive thompson test * decreased plantar flexion (contraction) * presence of a palable defect (palpation) * increased pasive ankle dorsiflexion (stretch) * will find it hard to push off during gait and also do a double or single leg heel raise
42
what does the **surgical managment** of an achilles tendon tear involve?
* 0-2 weeks - walking in boot with wedges and use of 2 crutches * 6-8 weeks boot * rehab - SL stance, leg press, stationary bike * by 6 weeks - working on ankle ROM * no stretching achilles for 6 months * more than 8 weeks and beyond - shoes with heel lift, seated/standing heel raise 50% weight hearing, PF with theraband
43
describe the epidemiology of **achilles tendinopathy**
* males can get it just as much as females * peak age - 40-59 years * distance runners and multi-directional sport is most common * sedentary people * common with systemic conditions * morning stiffness * 1 in 3 report bilateral symptoms
44
what is noticed with the physical examination of achilles tendinopathy? | contract, palpate and stretch
* pain with double/ single leg heel raise and pain with hop or jump * pain with ankle dorsiflexion * pain and thickness at site of tendinopathy * ROM may be altered
45
what are the common injuries that can occur in the peroneal tendon (fibularis tendon)?
* tenosynovitis - ie tendon sheath swelling * tendinopathy - overuse * tear * subluxing or dislocating tendons
46
what is plantar fasciopathy?
* degeneration and over use of the plantar fascia of the sole of the foot * plantar fascia - strong band of connective tissue that runs from the heel to the metatarsals
47
what are the potential clinical signs and symptoms of plantar fasciopathy?
* patients report localised heel pain on the medial side * worse standing after rest especially 1st thing in the morning * improves during the day * exacerbated with prolonged walking and exercise
