Ankle Arthrodesis Indications

Ankle Arthrodesis Contraindications

  • Talar AVN (consider Blair technique)
  • Peripheral neuropathy (relative; high nonunion rate; consider AFO/bracing)
  • Severe osteoporosis
  • Infection (consider fusion with external fixation)

Alternatives

  • Conservative care  (NSAIDs, soft-laced ankle gauntlet, AFO)
  • Arthroscopic ankle arthrodesis
  • Ankle arthrodesis in situ

Ankle Arthrodesis Pre-op Planning

  • see (Gougoulias NE, Foot Ankle Int 2007;28:695) for arthroscopic technique
  • -Patient Guides: eOrthopod,
  • For fusion after TAA failure see: (Cuplan P, JBJS 2007;89Br:1178)
  • Can use proximal humeral locking plate (Ahmad J, Foot Ankle Int 2007;28:977)
  • Ankle arthrodesis plates are available from Tournier and .....
  • Screw techniques: Acumed
  • Consider having external fixator available as an alternative if screw fixation is not rigi

Ankle Arthrodesis Technique

  • Sign operative site.
  • Pre-operative antibiotics, +/- regional block.
  • General endotracheal anesthesia
  • position. All bony prominences well padded.
  • Examination under anesthesia.
  • Prep and drape in standard sterile fashion.
  • Irrigate.
  • Close in layers.

Ankle Arthrodesis Complications

Ankle Arthrodesis Follow-up care

  • Post-op:bulky Jones dressing with posterior splint and side stirrup.  NWB
  • 7-14 Days:  Wound check, xrays, place in below knee cast.  NWB
  • 6 Weeks: Xray,  evaluate for callus and evaluate patient symptoms.  Place in short leg cast or walking boot.  Generally may gradually begin weight bearing at 7-10 weeks.
  • 3 Months: Begin full weight bearing.  Conitnue walking boot.
  • 4-5 Months: Xray, evaluate for solid fusion.  Discontinue walking boot and return to manual activities when solid union achieved.
  • 1Yr: Xray, outcome evaluation

Ankle Arthrodesis Outcomes

  • >90% fusion rate with arthroscopic ankle arthrodesis (Gougoulias NE, Foot Ankle Int 2007;28:695)
