Ankle: Exam 2 Flashcards
(156 cards)
Lateral Ankle Sprains
MOST COMMON LIGAMENT INJURED
ATFL
Lateral Ankle Sprain
MOST common ligament injured THEN….
ATFL FIRST
followed by:
CFL, PTFL
Lateral Ankle Sprain
MOI
Ankle PF and INversion
Lateral Ankle Sprain
Risk Factors
- Hx of PREV ankle sprain
- Do NOT use an EXT. Support
- Do NOT properly warm-up
- timing—-warm up peroneals!!!
- Do NOT have normal ankle DF ROM
- Do NOT participate in balance/proprioceptive prevention program when there is a hx of prev. injury
- this is often LAST PART OF REHAB***
Lateral Ankle Sprain
Clinical Presentation
- Localized pain @ Anterolateral ankle
- ATFL>CFL>PTFL
- Effusion (edema)
- POSSIBLE diff. bearing weight
- POSSIBLE ecchymosis (bruising)
-
why?
- sm. blood vessels ruptured during FIRST injury——following injuries have LESS ecchymosis****
-
why?
-
(+) Ant. Drawer Test and/or Talar Tilt Test
- remember Stabilize Medially if TESTING LATERAL SIDE
Anterior Drawer Test of the Ankle
- If assessing Medial (Deltoid) Ankle
- Stabilize laterally
- If assessing Lateral Ankle
- Stabilize medially
- Tests for injury of ATFL
- can also use for Deltoid Lig.
- Pt. seated over edge of table w/ ankle in SLIGHT PF (~20degs)
- Apply ANT. GLIDE of talus on stabilized tibia
- (+) Test= excess. translation of one side in comparison to opp. extremity
- Discuss/Understand Diff:
- Lateral aspect of talus translates too far anteriorly ==== Lat. Ankle sprain
- ENTIRE TALUS translates too far anteriorly==Lat & Med. side injury****
- Sn=.58
- 42% FN’s
- Sp= 1.00
- 100% Negs are Negative
- +LR=INF (want >10)
- VERY SURE YOU HAVE IT IF (+)
- -LR= .42 (want
- NOT SMALL ENOUGH TO BE SIG.
- cannot put a ton of stock in a negative test
Talar Tilt Test
*For Lateral Ankle sprain
- Tests for injury to the CFL
- pt lies SUPINE w/ ankle in neutral
- examiner brings ankle into INVERSION
- (+) Test= excess. motion compared to uninvolved side
- Sn= .50
- 50% FN’s
- Sp= .88
- 12% FP’s
- +LR= 4.00
- want >10
- -LR= .57
- want
- cannot put a ton of stock into a negative test
Lateral Ankle Sprain
Interventions: depends on severity
- RICE (24-48hrs or longer)
- Bracing
- aircast, Swedo, etc..
- taping as indicated
- Crutches
- IF unable to WB w/out pain
- Gradual active ankle ROM w/in limits of pain
-
Gradual PREs w/in limits of pain
- DF, EV****
- Gradual WB w/in limits of pain
- Balance/Proprioception ex’s
- Gradual progression of walking, running
- Manual Therapy as indicated
- **to correct Anterior Talar positional fault, OR Ant/Inf. Fibular positional fault
High Ankle Sprain
- Injury to Distal tibiofibular syndesmosis:
- AITFL–ant. inf. tibiofibular lig.
- PITFL– post. inf. tibiofibular lig.
- Interosseus lig.
- Interosseus memb.
- MOI:
- 3 proposed MOIs:
- ER of foot
* OR tibia rotating INT. on Planted Foot
- ER of foot
- Eversion of Talus
- Excessive DF
- 3 proposed MOIs:
- Mortise widens too much; Talus becomes unstable w/in mortise
- Risk factors
- skiing, football, soccer and other turf sports that involve planting of the foot and cutting
High Ankle Sprain
Clinical Presentation
- Pain localized to AITFL
- TTP of the AITFL
- Pain w/ active or passive ER of foot
- DF+EVERSION TEST
- Pain w/ active or passive forced DF
- DF+EVERSION TEST
- May have heel-rise gait pattern to AVOID excess. ankle DF/pain
- Antalgic gait w/ shortened stance phase on injured LE
- SEVERE swelling is RARE
- MAY be accompanied by deltoid (med.) lig sprain + Fibular Fx
-
(+) Squeeze Test
- compressing tib/fib together
Squeeze Test for High Ankle Sprain
- pt lies SUPINE or seated w/ leg off edge of table
- examiner grasps lower leg at midcalf and squeezes tib/fib together
-
(+) if proximal force** causes **distal pain near syndesmosis
- bc Distraction force caused @ distal end when you squeeze PROXIMALLY
- Sn= .30 (70% FN’s) Sp= .93 (7% FP’s)
- +LR= 4.60 (want >10) -LR= .75 (want
High Ankle Sprain
Interventions
-
Conservative Tx in the absence of fx (Sx for severe cases)
- RICE
- IMMED. NWB to prevent further injury;
- progress to WB as pain allows
- splint/brace/tape for mech. stability as needed
- GRADUAL progress. of AROM as pain allows
- GRADUAL progress of strengthening as pain allows
- GRADUAL progression of balance/proprio training as pain allows
- Gait training—–include AD if necessary
- Restore FXN, and return to sport/rec.
Medial (Deltoid Lig.) Ankle Sprain
RARE****
MOI:
- Injury to Deltoid Lig.
-
MOI:
- Eversion of ankle
Medial Ankle Sprain
Eversion Sprain
Clinical Presentation:
- sig. swelling
- tenderness over medial ankle
- ecchymosis over medial ankle
- Pain localized to medial ankle w/ valgus stress
-
INTERVENTION:
-
similar to Lat. Ankle Sprain
- BUT direction of motion to protect is Eversion
-
similar to Lat. Ankle Sprain
Chronic Ankle Instability
Recurrent ankle sprains AND repetitive episodes of giving way
Chronic Ankle Instability
Risk Factors
- INCd talar curvature
- NOT using ext. support
- NOT performing balance or proprio. ex’s following acute lateral ankle sprain
- Previous ankle sprain
Chronic Ankle Instability
Clinical Presentation:
- Hx of repeated ankle sprains/giving way
- Persistent pain
- DECd postural control
- INCd instability
Chronic Ankle Instability
Intervention
Non-OP vs
Surgical
- NON-OP—-similar to Lat. Ankle Sprain w/ emphasis on balance training
-
Surgical:
-
Lat. Ankle Repair
- __remember “REPAIR” is much less stable and you MUST BE MORE CAREFUL
-
Lat. Ankle Repair
Lateral Ankle Repair
Indications:
- Chronic ankle sprains or instability
- elective sx
- usually those under 40 and athletic
Lateral Ankle Repair
Gen. Sx Procedure
- Lat. incision made to access ATFL/CFL
- Ligs overlapped and sutured (BE CAREFUL W/ THESE!!!)
-
**First 6 wks MOST important AND vulnerable time for healing repair
-
AVOID:
-
Inversion & PF
-
why????
- bc THIS IS THE MOI!!!!!
-
why????
-
Inversion & PF
-
AVOID:
Recommended Interventions during Acute/Protected Motion Phase
- EXT. support and progressive WB (AD as needed)
- Manual therapy
-
soft tissue mobs+jt. mobs
- INCLUDING post. talar glide (for DF)
-
soft tissue mobs+jt. mobs
- Cryotherapy
- TherEX
Recommended Interventions during Subacute/Chronic Progressive Loading/Sensorimotor Traning Phase
- Manual Therapy
- Jt mobs, MWM to improve DF ROM, proprio and WB tolerance
- TherEX, functional+balance activities
- Sports related act. training
Ottawa Ankle Rules
*developed to det. need for radiographs after acute ankle injury 2* to risk of Fx
- Sn= 96.4-99% (+ Fx)
- IF they test NEGATIVE—-most likely NEGATIVE!!!

Ottawa Ankle Rules
Ankle X-Ray Series Req’d
Criteria:
- Any pain in Malleolar Zone AND:
- Bone tenderness @ Post. edge OR tip of Lat. Malleolus
- Bone tenderness @ Post edge OR tip of Med. Malleolus
- Inability to bear wt BOTH immed AND in ED
