3
Q
Pes cavus
A
Possible cause: xs supination
4
Q

A
Possible cause: xs pronation
1. “Too many toes sign”
5
Q
Sprain
A
Abnormal stretch/tear of ligament
6
Q
Strain
A
Abnormal stretch/tear muscle or tendon
7
Q
Inversion ankle sprains
A
- 90% ankle sprains
- Likely because:
A. Ankle usually in plantarflexion when wt comes down on inverted ankle
8
Q
Eversion ankle sprains
A
- <10% ankle sprains
- Unlikely because:
A. Medial ligaments stronger than lateral
B. Ankles usually dorsiflexed when wt comes down on exerted ankle
9
Q
Grade 1 ankle sprain
A
1. Stretching/partial tear of ligament A. Ant talofibular B. Calcaneofibular 2. Mech of injury A. Forces inversion and plantarflexion 3. Clinical presentation A. Mild tenderness and swelling B. Little/no fxn loss 1. Can bare wt and ambulate w/ min pain C. No mech instability of ankle 1. negative/equivocal clinical stress exam
10
Q
Grade 2 ankle sprain
A
- Partial/complete tear anterior talofibular ligament
- Stretching calcaneofibular ligament
- Mech of injury
A. Forced inversion and plantarflexion - Clinical presentation
A. Moderate tenderness and swelling
B. Mild to moderate ecchymosis
C. Tenderness to palpation
D. Some motion and fxn loss- Pain w/ wt bearing and ambulation
E. Mild to moderate instability of ankle - Mildly positive clinical stress exam
- Pain w/ wt bearing and ambulation
11
Q
Grade 3 ankle sprain
A
- Tear ant talofibular lig
- Tear calcaneofibular lig
- Partial tear post talofibular lig
- Partial tear tibiofibular lig
- Mech of injury
A. Forces inversion and plantar flexion - Clinical presentation
A. Severe tenderness and swelling
B. Severe ecchymosis
C. Tenderness to palpation
D. Motion and fxn loss- Incapable wt bearing or ambulation
E. Mech instability of ankle - Moderate to severe (+) clinical stress exam
- Incapable wt bearing or ambulation
12
Q
Clinical stress exams for ankle sprains
A
- Ant drawer test for ankle
2. Talar tilt
13
Q
Ankle sprain tx
A
1. Days 1-3 A. RICE B. Activity as tolerated C. Pain management D. OMT 2. Days 4+ A. Ice B. Heat after 48-72 hrs C. Pain management D. ROM exercises E. OMT F. PT as tolerate 3. Air cast/Velcro brace support w/ ambulation 4. Crutches if ambulation difficult 5. X-ray if can’t walk 6. Surgery rare lateral injury, more likely medial 7. Prolotherapy for chronic laxity
14
Q
High ankle sprain/syndesmotic injury
A
1. Stretching/tearing high ligs A. Ant inf tibiofibular lig B. Post inf tibiofibular lig C. Interosseous membrane 2. Clinical presentation A. No fracture: pain w/ dorsiflexion B. W/ fracture: can’t bear wt or ambulate 3. Clinical stress exam A. Compression test (w/ dorsiflexion) B. External rotation of foot and ankle
15
Q
High ankle sprain tx
A
- Surgical stabilization
A. Unstable ankle
B. Frank diastasis
C. In >4mm widening of medial clear space on x-rays - Conservative tx
A. NSAIDs
B. RICE
C. 1st phase- Non-wt bearing boot 5-7 days (passive ROM exercises w/o boot several times/day)
D. 2nd phase - Transition full wt bearing in brace (gait and light proprioceptive exercises)
E. 3rd phase - Start when painless hop on foot and ankle
- Protected full wt bearing
- Resistive exercises, multi-axial movement, proprioceptive training
- Non-wt bearing boot 5-7 days (passive ROM exercises w/o boot several times/day)
16
Q
Peroneal muscle strain
A
1. Risk factors A. Ankle injury B. Repeat inversion injuries C. Pes planus D. Gait w/ excessive eversion E. Poor fitting athletic equipment 2. Clinical presentation A. Pain and swelling along lateral ankle B. Feeling weakness/instability C. If retinaculum is torn: snapping sensation along lateral malleolus
17
Q
Peroneal muscle testing
A
- Resisted eversion
A. Assesses peroneus brevis - Resisted eversion and dorsiflexion w/ palpation post lateral malleolus
A. Assesses subluxation peroneus brevis due to disruption retinaculum
18
Q
Peroneal muscle strain tx
A
1. Mild to moderate cases A. RICE B. Pain management C. PT (ankle ROM, proprioceptive training, muscle strengthening) 2. Severe cases A. Walking boot B. Surgery if subluxing (prevent tendon rupture) 3. Prevention A. Adequate time for rehab B. Slow return to activity C. Prep for sports D. Properly fitting equipment
