Ankle arthrodesis using a tibio-calcaneal external fixator.

Area of Science:

• Orthopedic Surgery
• Podiatric Medicine
• Musculoskeletal Research

Background:

• Ankle-talar arthritis significantly impacts patient mobility and quality of life.
• Current treatment options for severe ankle arthritis include arthrodesis (fusion).
• Open ankle arthrodesis is a surgical procedure to fuse the ankle joint.

Purpose of the Study:

• To evaluate the efficacy and patient satisfaction of open ankle arthrodesis for ankle-talar arthritis.
• To assess the union rate and functional outcomes following this surgical intervention.

Main Methods:

• A cohort of 23 patients with primary or secondary ankle-talar arthritis underwent open ankle arthrodesis.
• The Citieffe/CH-N external fixator system was utilized, with pins placed in the tibia and calcaneus.
• Follow-up assessments included union rates, time to union, and patient-reported satisfaction.

Main Results:

• A high union rate of 91% (21 out of 23 patients) was achieved.
• The average time to achieve bone union was 13 weeks (range: 12-16 weeks).
• The mean follow-up period was 6 years, with 91% of patients reporting satisfaction with the surgical results.

Conclusions:

• Open ankle arthrodesis using the Citieffe/CH-N external fixator is an effective treatment for ankle-talar arthritis.
• The procedure demonstrates a high rate of bony union and significant patient satisfaction.
• This surgical approach offers a reliable solution for patients suffering from debilitating ankle arthritis.
