Ankle fracture (peds)
Revision as of 15:59, 22 March 2016 by Ostermayer (talk | contribs) (Text replacement - "Category:Peds" to "Category:Pediatrics")
Background
- More fractures and fewer sprains since physis is weaker than surrounding ligaments
- Usually Salter-Harris I or II
Diagnosis
- TTP of growth plate, soft tissue swelling
- Distinguish from lateral ligamentous sprain by presence of point tenderness over physis
- Imaging
- May only show soft tissue swelling at lateral fibula
Types
- Salter-Harris I or II
- Manage w/ closed reduction if any displacement present, followed by immobilization
- Salter-Harris III (25%)
- Require open reduction of any displacement
- Tillaux Fracture
- Salter-Harris type III of the anterolateral portion of the distal tibia
- ATFL avulses off the distal tibia
- May need oblique view to distinguish from triplane fx
- Usually requires surgical reduction
- Salter-Harris type III of the anterolateral portion of the distal tibia
- Triplane Fracture
- Medial portion of distal tibia growth plate closes before lateral aspect
- While normal, this causes 18-month period of vulnerability until lateral aspect closes
- Planes
- Plane 1: Lateral side of tibia through growth plate to fused medial aspect of physis
- Plane 2: Sagittal through epiphysis
- Plane 3: Coronal through distial tibial metaphysis
- Imaging
- Appears as Salter III on AP, Salter II on lateral
- Management
- CT to delineate injury
- Ortho consult; closed reduction sufficient in most cases
Management
- If nondisplaced immobilize, ortho f/u optional
- Short-Leg Posterior Splint
