Combined Total Talus Replacement and Total Ankle Arthroplasty

Area of Science:

• Orthopaedic Surgery
• Bone Biology
• Reconstructive Surgery

Background:

• Avascular necrosis (AVN) of the talus is a complex condition with poor treatment outcomes.
• Extensive talar AVN leads to complications like non-union and premature arthritis, challenging surgical management.
• Total ankle arthroplasty is an option for end-stage ankle arthritis, but bone stock deficiency due to AVN poses issues.

Purpose of the Study:

• To present a surgical technique for managing end-stage ankle arthritis with extensive talar osteonecrosis.
• To address cases of failed total ankle replacement with talar component collapse secondary to AVN.
• To offer an anatomic treatment for patients with severely deficient bone stock from talar necrosis.

Main Methods:

• Description of a surgical technique for extensive talar osteonecrosis and associated ankle arthritis.
• Application of the technique in patients with prior total ankle replacement and talar component collapse.
• Focus on providing an anatomic reconstruction for deficient bone stock.

Main Results:

• The presented technique aims to provide a more anatomic treatment option.
• It addresses severe bone stock deficiency resulting from talar necrosis.
• The technique is applicable to patients with ankle arthritis or failed ankle replacements due to AVN.

Conclusions:

• The described technique offers a potential solution for complex cases of talar AVN with ankle arthritis or failed arthroplasty.
• This approach may provide a more anatomic reconstruction in patients with significant bone loss.
• Long-term outcome evaluation is necessary to fully assess the efficacy of this technique.
