Syndesmosis Injuries
11-18 of all ankle sprains Longer recovery v.s.
Lateral sprains Men v.s. Women?
3
Bone Anatomy
  • Tibia
  • Articular Surface
  • Fibula
  • Articular Surface
  • Talus
  • Dome

Provides Stability Proper Ankle Function
Articular Surface
4
Snydesmosis Ligaments
  • AIFL- Chaputs Tubercle
  • Most Vulnerable
  • PIFL- Wagstaffes Tubercle
  • Strongest
  • ITFL- Thickening of PIFL
  • IM- Fibrous tissue
  • Transmit force
  • IL- Thickening of IM

5
Biomechanics
  • Mechanism of Injury
  • Eversion
  • Dorsiflexion
  • Pronation
  • Closed Pack Position
  • Forces the talus against the fibula
  • Widening of mortise
  • 1mm lateral shift increases joint
    surface pressure by 42

Associated injuries?
6
Clinical Examination
  • History
  • ER with DF
  • Contact
  • None Contact
  • Acute v.s. Chronic
  • Observation
  • Edema
  • Eccymosis
  • Antalgic gait
  • Possible Deformity?

7
Clinical Examination
  • Palpation
  • Tenderness Length

Nussbaum et al.
  • Special Test

Squeeze Test Dorsiflexion Test Kleigers
Test Cross-leg Test

Imaging Techniques
X-RAY
  • Radiographs
  • AP, Lateral, Mortise Views
  • AP View
  • Fractures
  • Tibiofibular clear space
    widening of 6 mm
  • Tibiofibular overlap gt 42
    Fibula Width
  • Medial clear space widening gt 4mm
  • Lateral View
  • Non weight bearing ER
  • Fractures

  • AP View

Heterotopic Ossification
13
Imaging Techniques
MRI CT
  • MRI (Magnetic Resonance Imaging)
  • Frontal, Axial, Saggital Views
  • High sensitivity and specificity
  • More reliable detecting disruptions
  • CT (Computed Tomography)
  • More effective detecting minor disruptions
  • Less Cost v.s. MRI

Imaging Techniques
MRI
  • Axial Views

West Point Instability Scale
Grade I
Grade II
Grade III
Edema Ecchymosis Localized Mild Localized Moderate Diffuse Severe
Weight Bearing Ability Full or Partial Without Significant Pain Difficult Without Crutches Impossible Significant Pain
Ligament Damage Ligament Stretch Partial Tear Complete Tear
Ligament Involvement AIFL AIFL IL Possible AD AIFL/PIFL IL AD
16
Treatment Criteria
Based on Patients Goals Length of
Symptoms Severity of Injury
  • Conservative
  • Non Conservative

Grade I Non-Fractures Stable Grade II
Grade III Unstable Grade II Fractures Chronic
Injury
17
Conservative Protocols
  • Results vary patient to patient
  • Grade I Injuries 2-4 Weeks RTP
  • Grade II Injuries 6-8 Weeks RTP
  • Without Instability or Fractures

18
Conservative Protocols
  • Phase I (0-5 Days) or (5-14Days)
  • Immobilize
  • Reduce Pain
  • Reduce Inflammation
  • Cryotherapy
  • E-Stim
  • Increase ROM
  • Manual 30 PF Stretch
  • Ankle Pumps
  • Toe Curls
  • Towel Stretch

19
Conservative Protocols
  • Phase II (6-10 Days) or (2-4 weeks)
  • Immobilize Grade II
  • Reduce Pain
  • Reduce Inflammation
  • Proprioception
  • Increase Flexibility
  • Increase ROM
  • Increase Strength
  • CV Endurance

20
Conservative Protocols
  • Phase III (18-25 Days) or (4-8 Weeks)
  • Protect Injury
  • Reduce Pain
  • Increase Pain free Activity
  • Sports Specific
  • Proprioception
  • Increase Strength
  • Increase Flexibility
  • CV Endurance

21
Conservative Protocols
  • Phase III (18-25 Days) or (4-8 Weeks)
  • Sports Specific

Conservative Protocols
Return To Play Criteria
  • Full Strength
  • Full ROM
  • Functional Test
  • Physician Clearance
  • Protect Injury

23
Operative Treatment
Arthroscopy
  • Goal is to restore structures, and mobility
  • Open Reduction Internal Fixations
  • Autographs
  • Modified Brostrum Technique
  • 4.5 mm Cortical Screws
  • Complications
  • Screw Breakage
  • Screw Type
  • Infection
  • Calcification Joint Stiffness

25
Post-Operative Protocols
Arthroscopy
  • Results vary patient to patient
  • Grade III Injuries 4-8 Months RTP
  • Non Weight Bearing 6-8 Weeks
  • Screw Removal _at_ 3 Months
  • Follow-up Imaging every 2 weeks

26
Post-Operative Protocols
  • Phase I (1-3 Weeks)
  • Phase I- Conservative Rehabilitation
  • Immobilize Non Weight Bearing
  • Protect Wound
