Ankle: Pathologies 3 Flashcards
Peroneal tendinopathy is most often associated with what injury?
Lateral ankle sprains
Peroneal tendinopathy: (%) of peroneal dysfunction occurs with ankle sprains
95%
Peroneal tendinopathy SHOULD be suspected after
Lateral ankle sprain
Peroneus brevis injuries occur where?
- Lateral and posterior
- 2-3 cm distal to lateral malleolus
Peroneus longus injuries occur where?
- in the cuboid tunnel OR
- base of 1st MTP
Peroneal tendinopathy: Swelling?
Not typical
Peroneal tendinopathy: Location of pain
- Posterior or distal to lateral malleolus
- around cuboid
Peroneal tendinopathy: typical foot characteristics
- varus hindfoot
- forefoot varus
- limited ankle DF
Peroneal tendinopathy: In addition to lateral ankle sprain, may also have a history of
chronic lateral ankle pain and instability
Peroneal tendinopathy: Pain in what phase of gait
Terminal stance
Peroneal tendinopathy: pain with what movements?
- Unilateral heel raise
- passive DF and inversion
- resisted PF/eversion
Peroneal tendinopathy: Risk factors
- age related degeneration
- inflammatory arthritis
- HTN
- DM
- obesity
- less frequently - acute traumatic rupture
Peroneal tendinopathy: Differential dx
- Achilles tendinopathy
- high ankle sprain
- sinus tarsi syndrome
- posterior ankle impingement
- cuboid fx
- fibular fx
With peroneal tendinopathy, need to strengthen what group?
Evertors
Peroneal tendinopathy: what type of insert may be helpful?
Lateral heel wedge
Posterior tibial tendinopathy
May need foot orthosis to decrease
Pronation
Posterior tibial tendinopathy:
Consider immobilization in short leg cast for (duration)
2-3 weeks
Salter Harris fractures occur in which group
Children
Salter Harris fx: involves what structures
Growth plate in long bones
Salter Harris fx: How many types?
5
Salter Harris fx: Type 1
- Fx through the physis
- no involvement of the bone of the epiphysis or metaphysis
Salter Harris fx: Type 2
- Fx involving part of the metaphysis
- extends to the physis
Salter Harris fx: Type 3
- fx involves the epiphysis
- extends into the physis
Salter Harris fx: Type 4
Fracture involves the epiphysis, metaphysis, and extends into the physis
Salter Harris fx: type 5 involves only the
Physis
Salter Harris fx: Type 5
Compressive deformity of the growth plate
only involves the physis
