Stress fx of the mets
Calcaneus
Foot fx common MOI
overuse or trauma
Stress fx symptoms
swelling
tenderness
gait change
reproduction of cc by performing activity
Special tests stress fx
Metatarsal compression test
Tuning fork
Ottawa Ankle Rule Ankle X-Ray required if
- Pain in anterior aspect of medial or lateral malleoli and anterior talar dome area
- Bone tenderness at posterior medial malleolus
- Bone tenderness at lateral malleolus
- Inability to bear weight on the limb immediately after the injury and in the ER
Ottawa Ankle Rule Foot X-Ray required if
- Pain in dorsal medial and lateral aspect of the midfoot
- Bone tenderness at the base of the 5th metatarsal
- Bone tenderness at navicular
- Inability to bear weight on limb immediately after the injury and in the ER
Metatarsal Compression Test
Morten’s Test
Positive pain with metatarsal fx or neuroma
False positive in pt with metatarsalgia
Unclear evidence to support this
Tuning Fork
For fibular fx
Pt supine, stethoscope is placed on fibular head, hit a tuning fork on lateral malleolus
Positive if there is a different sound in bilateral comparison
Minimal evidence to support it
Achilles Tendon Rupture
MOI: trauma jumping or landing, prolonged steroid use?
Symptoms: “Hit” in the back of the anke, “pop”, weak
Special tests:
-Bilateral Toe Raise
-Thompsons test
Thompson Test
Squeeze gastroc w/ patient in supine, foot should PF
Positive test if nonresponsive ankle PF during test
Unclear evidence to support this
Deep Vein Thrombosis
MOI: Insidious, after recent surgery or immobilization Signs/symptoms -calf pain, ankle swelling -Antalgic gait Special Tests: -Homan's sign -Calf Swelling -Well's CPR for DVT
Homan’s Sign
Positive test is popliteal and/or calf pain
Many presentations may lead to false positive
Minimal evidence to support this
Calf Swelling
Positive test if bilateral comparison is difference of 15 mm for men or 12 mm for women
Minimal evidence to support this
Well’s Clinical Prediction Rule for DVT
Asking questions regarding recent events
Positive test related to score on the test
Strongly supported by evidence
Great for screening and ruling out an ER trip
Ligamentous Injuries
Inversion/Supination: Lateral ligaments
Eversion/Pronation: Deltoid ligaments
Syndesmosis Injuries
Acute Lateral Ankle Sprain
MOI: Trauma Inv/PF Symptoms: -Difficulty in activity -Lateral ankle pain -Medial ankle pain: Kissing lesion -Swelling -Ecchymosis -Painful WB and ROM
Kissing Lesion
Medial aspect compromised because of medial malleolus and talus contact during inversion
Grade I Acute Ankle Sprain
Mild (2 weeks rehab)
-Mild effusion, no hemmorrhage
-Negative anterior drawar, negative varus laxity
-Pain with inversion and PF
Little to no limp, but trouble with hopping
Grade II Acute Ankle Sprain
More swelling, hemmorrhage likely present
Positive anterior drawer, no varus laxity at neutral
Limping with walking, unable to raise on toes/hop/run
Grade III Acute Ankle Sprain
Immobilization 1-10 days, 8-10 weeks of rehab Diffuse swelling, hemmorrhage Significant instability Complete tears of ATFL and CFL Unable to FWB Decreased ROM
Chronic Ankle Sprains
Patient reports giving way with no pain in between inversion episodes
Leads to chronic instability
If ll. are lengthened beyond patients control then surgery is necessary
Anterior Drawer Ankle
Positive test if pain reproduced laterally or excessive gapping betwen the distal lateral malleolus and calcaneous
Longitudinal fibularis tendonitis/subluxation
-Swollen, tender, painful posterior to lateral malleolus
-Pain with AROM eversion
-Minimal response to PT intervention
May seem like lateral ankle sprain
OCD/Loose bodies within joint
Effusion
Crepitus felt when palpating medial/lateral talus
“catch” “lock” “give way”
Can look like lateral ankle sprain
Anteriorlateral synovitis or impingement
No swelling Point tenderness at anteriolateral junction of tib/fib Pain with DF, Increased activity, stairs May look like lateral ankle sprain Use Forced DF test to rule in or out
Talar Tilt
- Positive if pain is reproduced or excessive gapping between the distal lateral malleolus and calcaneous
- DF to bias PTFL, Neutral for CFL, PF for ATFL
