Ankle arthrodesis, or ankle fusion, effectively relieves pain and disability from arthritis when nonoperative treatments fail. Careful patient selection and surgical technique are crucial for successful outcomes, despite potential risks like nonunion.

Area of Science:

  • Orthopedic Surgery
  • Podiatric Medicine
  • Musculoskeletal Conditions

Background:

  • Ankle arthritis and deformity cause significant pain and functional disability.
  • Nonoperative treatments are often insufficient for severe cases.
  • Ankle arthrodesis is a surgical option for eligible patients without subtalar pathology.

Purpose of the Study:

  • To review the indications, techniques, and outcomes of ankle arthrodesis.
  • To highlight factors influencing successful ankle fusion.
  • To discuss complications and risk factors for nonunion.

Main Methods:

  • Review of surgical techniques for ankle arthrodesis, emphasizing open approaches with compression and internal fixation.
  • Discussion of patient selection criteria, including ruling out subtalar joint involvement.

  • Analysis of factors affecting foot positioning for optimal limb alignment and function.

    • Main Results:

    • Successful ankle arthrodesis can provide relief from disabling ankle arthritis, deformity, and pain.
    • Reported nonunion rates can be as high as 40%.
    • Osteonecrosis of the talus and smoking are identified risk factors for nonunion.

    Conclusions:

    • Ankle arthrodesis is a reliable procedure for carefully selected patients with severe ankle arthritis.
    • Meticulous surgical technique and appropriate patient selection are paramount.
    • Awareness and mitigation of risk factors like osteonecrosis and smoking can improve union rates.
