A 35-year-old male patient suffered a talus bone fracture due to a fall from height, and after approximately 10 years, developed avascular necrosis of the bone. The patient has visited the doctor due to pain and inability to walk and has been referred to the Fanavaran Jarah Yar Sharif Company.

Pre-operative simulation and planning

By analyzing the contralateral limb of the patient, the position of the calcaneus was determined to prevent limb shortening, and the prosthesis height was calculated.

Ankle Fusion Cage was designed for the insertion of retrograde intramedullary nail. To facilitate filling the cage with autograft and to enhance the strength of the component, the prosthesis was designed with a truss structure.

The prosthesis was manufactured using 3D printing technology and, following post-processing and sterilization with gamma radiation, it was delivered to the physician.
