Custom titanium prostheses, made using 3D printing technology, are a suitable alternative to allografts in ankle joint fusion surgeries. In the following animation, a 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. The prosthesis was designed considering the healthy side of the limb, and after determining the treatment plan and obtaining approval from the doctor, The prosthesis was made using 3D printing with titanium material.
Some features of the ankle fusion cage are as follows:
- Prevention of allograft resorption and associated infection
- Prevention of limb shortening
- A porous structure to allow filling the prosthesis with autograft for enhanced bone in-growth and stabilization of the implant
- The ability to design the prosthesis according to the patient’s bone defect
- Compatibility with various ankle joint fusion systems
The personalized ankle fusion cage prostheses made from titanium are fully biocompatible, and the possibility of osseointegration with this alloy has been proven.
