Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering

Background:

  • Idiopathic necrosis of the talus requires effective treatment options.
  • Total talar replacement is a potential solution for debilitating talar pathologies.

Observation:

  • A 73-year-old female patient presented with idiopathic necrosis of the talus.
  • A custom total talar prosthesis was designed using CT imaging of the contralateral limb.

Findings:

  • Surgical resection of the necrotic talus and implantation of the custom prosthesis were performed.
  • Postoperatively, the patient showed a dramatic improvement in the Foot Function Index (FFI) from 95.9% to 4.7%.
  • American Orthopedic Foot and Ankle Society (AOFAS) scores improved from 0 pre-operatively to 94 post-operatively at 12 months.

Implications:

  • Custom total talar replacement demonstrates highly favorable outcomes for talar necrosis.
  • This approach offers a viable limb-sparing option for complex talar conditions.
  • Further research with longer follow-up is warranted to confirm long-term efficacy.
