Q

describe in 5 steps the pathogenesis of hallux valgus

A

lateral angulation of great toe
tendon pull realigned to lateral of toe
vicious cycle of increase pull and deformity
sesamoid bone sublux - less weight through big toe
deformities of lesser toes occur

25
Diagnosis of mortons neuroma - name of clinical sign
mulders click | USS/MRI
26
Management of mortons neuroma
injection for small lesions | excise lesion and some of normal nerve
27
If no known cause of metatarsalgia what should you consider?
tight gastrocnemius
28
non op management of RA forefoot
shoewear, orthotics and activity
29
op - RA forefoot
1st MTPJ arthrodesis is gold standard | 2-5th toe excision arthroplasty
30
3 midfoot problems
ganglia | OA and plantar fibromatosis
31
Where do dorsal foot ganglia arise from?
tendon sheath or joint
32
aetiology of dorsal foot ganglia
idiopathic underlying arthritis underlying tendon pathology
33
symptoms of ganglia
pain from shoe wear pressure or underlying problem
34
Treatment of ganglia
aspirate or family bible | excise
35
% return rate of ganglia excision
50
36
3 types of midfoot arthritis
post traumatic, OA, RA
37
3 treatments of arthritis in midfoot
non op = activity/shoes/orthotics x-ray guided injections fusion
38
When is plantar fibromatosis symptomatic?
very large or weightbearing area
39
non op - plantar fibromatosis
avoid pressure - shoes/orthotics
40
other treatments of pantar fibromatosis
excise radiotherapy radiotherapy and surgery
41
5 hindfoot problems
``` ankle osteoarthritis cavovarus foot achilles tendinosis plantar fasciitis tibialis posterior dysfunction ```
42
Describe achilles tendinosis
degenerative/overuse condition with little inflammation
43
Who does paratendonopathy affect?
athletes, 30-40, males
44
Who does tendonopathy affect?
non athlete, obese, over 40, steroids, DM
45
Symptoms of achilles tendinopathy
pain on exercise or after exercise | recurrent and difficulty fitting shoes
46
Diagnosis of achilles tendinopathy and the name of tests
clinical = Simmonds squeeze test and matles angle of dangle | USS/MRI
47
non op - achilles tendinopathy
activity/weight loss/shoes - slight heel/physio/ECST/immobilise
48
op - achilles tendinopathy
gastrocnemius recession | release and debridement of tendon
49
Describe fasciosis
chronic degenerative change with disorganised blood vessels, no inflammatory cells and fibroblast hypertrophy cannot make ECM needed for remodelling
50
Aetiology of plantar fasciitis
unknown/obese/athletes/standing/poorly padded shoes/foot and lower limb deformities/tight gastrosoleus
51
4 symptoms of plantar fasciitis
pain in morning or after rest pain at origin of plantar fascia 2 years + duration
52
differential diagnosis of plantar fasciitis
arthritis calcaneal pathology nerve entrapment syndrome
53
Diagnosis of plantar fasciitis
mainly clinical | x-rays, USS, MRI
54
9 treatments of plantar fasciitis
``` NSAIDS ice physiotherapy CCS injections orthoses - heel pads stretching rest night splinting weight loss ```
55
5 newer treatments for plantar fasciitis
``` extracorpeal shockwave therapy Nitric oxide endoscopic/open surgery platelet rich plasma topaz plasma coblation ```
56
aetiology of ankle arthritis
46 years, post trauma, idiopathic
57
Symptoms of ankle arthritis
pain and stiffness
58
diagnosis of ankle arthritis
clinical, radiographs and CT
59
non op - ankle arthritis
weight loss/activity/analgesia/physio/steroid injections
60
op - ankle arthritis
anterior symptoms - arthroscopic anterior debridement arthrodesis is the gold standard joint replacement
61
Clinical diagnosis of posterior tibial tendon dysfunction
double and single heel raise
62
What Is posterior tibial tendon dysfunction a common cause of?
acquired flat feet
63
3 managements of posterior tibial tendon dysfunction
orthotics - medial arch support reconstruct tendon triple fusion
64
Diagnosing posterior tibial tendon dysfunction
clinical or MRI
65
Why does diabetic foot ulcers occur?
peripheral neuropathy lack of patient education poor blood supply ANS dysfunction - less sweating - dry cracked skin
66
Treatment of diabetic foot ulcer
prevention | modify --> smoking, DM control, vascular supply, shoes, deformity, infection, nutrition
67
Surgery for diabetic foot ulcer
improve vascular supply amputate debride ulcers correct deformity
68
prognosis for diabetic foot ulcer statistics
15% diabetics develop 50% 5ys 85% diabetic amputations due to this 25% --> amputation
69
aetiology of charcot neuropathy
neuropathy causes diabetes syphilis
70
2 types of charcot foot
neurotraumatic - lack of proprioception and protective pain sensation neurovascular - abnormal ANS leads to increased blood supply and bone resorption
